Abstract
Orbital pathologies can be broadly classified as ocular lesions, extraocular soft-tissue pathologies (non-neoplastic and neoplastic), and bony and traumatic lesions. In this paper, we discuss the key imaging features and differential diagnoses of bony and traumatic lesions of the pediatric orbit and globe, emphasizing the role of CT and MRI as the primary imaging modalities. In addition, we highlight the adjunctive role of ocular sonography in the diagnosis of intraocular foreign bodies and discuss the primary role of sonography in the diagnosis of traumatic retinal detachment.

Abstract
A rare benign bone condition called monostotic fibrous dysplasia (MFD) is characterized by the growth of fibrous tissue in place of a normal bone. It may lead to deformity in the affected bone, pain, and a pathologic fracture due to bone weakness. Hereunder, a case report of MFD in a 17-year-old male adolescent presenting to the hospital with localized bone pain and swelling in his right tibia is presented. After clinical examination and radiographic imaging, a provisional diagnosis of benign osteolytic lesion was considered. A magnetic resonance imaging (MRI) scan of the leg suggested the possibility of fibrous dysplasia or adamantinoma. The patient was managed with an intralesional curettage of the dysplastic bone and packing the cavity with blocks of a synthetic bone. The excised material was sent for histopathology, which established the diagnosis of fibrous dysplasia.

Abstract
There is a wide spectrum of craniofacial bone disorders and dysplasias because embryological development of the craniofacial region is complex. Classification of craniofacial bone disorders and dysplasias is also complex because they exhibit complex clinical, pathological, and molecular heterogeneity. Most craniofacial disorders and dysplasias are rare but they present an array of phenotypes that functionally impact the orofacial complex. Management of craniofacial disorders is a multidisciplinary approach that involves the collaborative efforts of multiple professionals. This review provides an overview of the complexity of craniofacial disorders and dysplasias from molecular, clinical, and management perspectives.

Abstract
CONTEXT Pain is a poorly managed aspect in fibrous dysplasia/McCune-Albright syndrome (FD/MAS) because of uncertainties regarding the clinical, behavioral, and neurobiological underpinnings that contribute to pain in these patients. OBJECTIVE Identify neuropsychological and neurobiological factors associated with pain severity in FD/MAS. DESIGN Prospective, single-site study. PATIENTS Twenty patients with FD/MAS and 16 age-sex matched healthy controls. INTERVENTION Assessments of pain severity, neuropathic pain, pain catastrophizing (pain rumination, magnification, and helplessness), emotional health, and pain sensitivity with thermal quantitative sensory testing. Central nervous system (CNS) properties were measured with diffusion tensor imaging, structural magnetic resonance imaging, and functional magnetic resonance imaging. MAIN OUTCOME MEASURES Questionnaire responses, detection thresholds and tolerances to thermal stimuli, and structural and functional CNS properties. RESULTS Pain severity in patients with FD/MAS was associated with more neuropathic pain quality, higher levels of pain catastrophizing, and depression. Quantitative sensory testing revealed normal detection of nonnoxious stimuli in patients. Individuals with FD/MAS had higher pain tolerances relative to healthy controls. From neuroimaging studies, greater pain severity, neuropathic pain quality, and psychological status of the patient were associated with reduced structural integrity of white matter pathways (superior thalamic radiation and uncinate fasciculus), reduced gray matter thickness (pre-/paracentral gyri), and heightened responses to pain (precentral, temporal, and frontal gyri). Thus, properties of CNS circuits involved in processing sensorimotor and emotional aspects of pain were altered in FD/MAS. CONCLUSION These results offer insights into pain mechanisms in FD/MAS, while providing a basis for implementation of comprehensive pain management treatment approaches that addresses neuropsychological aspects of pain.

Abstract
PURPOSE OF REVIEW The purpose of this review is to provide a comprehensive overview into the diagnosis and management of fibrous dysplasia (FD) in children. RECENT FINDINGS FD is a mosaic disorder arising from somatic Gα s variants, leading to impaired osteogenic cell differentiation. Fibro-osseous lesions expand during childhood and reach final disease burden in early adulthood. The mainstay of treatment focuses on surgical correction of skeletal deformities, physiatric care, and medical management of associated hyperfunctioning endocrinopathies. Bisphosphonates may be helpful to treat bone pain, but do not alter lesion quality or progression. Emerging evidence suggests that the RANKL inhibitor denosumab may be effective in improving lesion activity and mineralization, however further studies are needed to determine the potential utility of this and other novel therapies, particularly in children with FD. SUMMARY Management of children with FD has unique challenges related to skeletal growth and age-related lesion progression. Inclusion of children in clinical research is critical to develop effective treatment strategies to treat FD lesions and prevent their development.

Abstract
BACKGROUND The co-existence of meningioma and craniofacial fibrous dysplasia (CFD) is rare. Due to the similar radiological characteristics, it is challenging to differentiate such co-existence from solitary hyperostotic meningioma resulting in a dilemma of prompt diagnosis and appropriate intervention. METHOD We conducted a retrospective review of the data from 21 patients with concomitant meningioma and CFD who were treated at Beijing Tiantan Hospital from 2003 to 2021. We summarized their clinicopathological features and performed a comprehensive literature review. Additionally, we tested the characteristic pathogenic variants in exon 8 and 9 of GNAS gene and the expression of corresponding α-subunit of the stimulatory G protein (Gαs) related to CFD to explore the potential interactions between these two diseases. RESULTS The cohort comprised 4 men and 17 women (mean age, 45.14 years). CFD most commonly involved the sphenoid bone (n = 10) and meningiomas were predominantly located at the skull base (n = 12). Surgical treatment was performed in 4 CFD lesions and 14 meningiomas. Simpson grade I-II resection was achieved in 12 out of the 14 resected meningiomas and almost all of them were classified as WHO I grade (n = 13). The mean follow-up duration was 56.89 months and recurrence was noticed in 2 cases. Genetic study was conducted in 7 tumor specimens and immunohistochemistry was accomplished in 8 samples showing that though GNAS variant was not detected, Gαs protein were positively expressed in different degrees. CONCLUSIONS We presented an uncommon case series of co-diagnosed meningioma and CFD and provided a detailed description of its clinicopathological features, treatment strategy and prognosis. Although a definite causative relationship had not been established, possible genetic or environmental interplay between these two diseases could not be excluded. It was challenging to initiate prompt diagnosis and appropriate treatment for concomitant meningioma and CFD because of its similar radiological manifestations to meningioma with reactive hyperostosis. Personalized and multi-disciplinary management strategies should be adopted for the co-existence of meningioma and CFD.

Abstract
BACKGROUND McCune-Albright syndrome is a rare disorder characterized by polyostotic fibrous dysplasia (FD), café-au-lait skin pigmentation, and endocrine dysfunction. Extensive FD in the craniofacial region can present significant challenges in terms of disease control and carries a high risk of permanent visual impairment. METHODS We present a case of medically and surgically resistant FD that required nine optic nerve decompressions. RESULTS The condition was ultimately controlled with the use of the denosumab agent. CONCLUSION The case highlights the importance and potential efficacy of denosumab in resistant FD management, particularly in cases involving sensitive organs.

Abstract
BACKGROUND Fibrous dysplasia is a congenital disorder in which normal bone is replaced by fibro-osseous tissue or irregular trabeculae of woven bone intermixed with mature collagenous tissue. A single or multiple bones are affected. This rare bone disorder has three clinical patterns including monostotic, polyostotic, and that associated with McCune–Albright syndrome. Most studies report primary fibrous dysplasia. However, a few cases of recurrent monostotic fibular fibrous dysplasia have been reported. Here, we report a therapeutic strategy for recurrent fibular fibrous dysplasia.
CASE SUMMARY A 4-year-old boy was admitted for persistent pain in the left lower limb and abnormal gait over the previous 9 mo. He had no history of present or past illness. Preoperative imaging data showed erosion-like changes with bone expansion of the left middle and lower fibular segment. Tumor tissue in the fibular bone marrow cavity was removed by curettage, and rapid intraoperative pathological examination suggested fibular fibrous dysplasia. An allograft was implanted into the fibular medullary cavity. However, he was readmitted with clinical symptoms including persistent pain, abnormal gait, and local swelling at the age of 6 years. He was diagnosed with recurrent fibular fibrous dysplasia based on the second medical examination. He underwent fibular bone tumor radical resection and longus fibular allograft transplantation combined with fibular bone locking plate and screws. Good host bone to allogenic bone graft fusion was observed by the physician on postoperative regular follow-up.
CONCLUSION Radical resection of fibrous dysplasia and longus fibula allograft combined with internal fixation for reconstruction are suitable for the treatment of recurrent monostotic fibular fibrous dysplasia.

Abstract
Fibrous dysplasia is a rare benign bone disorder characterized by the replacement of normal bone with fibroblastic and osteoblastic tissue. We present a case of monostotic fibrous dysplasia in a 25-year-old male patient. The case highlights the clinical presentation, radiographic features, and management approach for this condition. This report aims to contribute to the understanding of fibrous dysplasia and its management options. A 25-year-old male presented with a chief complaint of persistent left hip pain. The pain was described as a dull ache, associated with difficulty in weight-bearing activities. There was no history of trauma or constitutional symptoms. Physical examination revealed externally rotated left lower limb. Range of motion of the left hip could not be assessed due to pain, with no neurological deficits noted. Initial imaging included plain radiographs of the right femur, which demonstrated a radiolucent lesion with a ground-glass appearance and cortical thinning. Magnetic resonance imaging of both hip joints reveals an irregular T2 hyperintense and T1 hypointense lesion involving the left femoral neck; moreover, few tiny cystic spaces are seen within the lesion. Part of the lesion is extending into the superior-lateral aspect of the femoral head and surrounding bone marrow edema with minimal left hip joint effusion, features suggestive of a primary bony tumour. Plain computed tomography (CT) of the hip joint and pelvis was suggestive of an expansile lytic lesion with thin bony septation within and thick sclerotic margin in the left femoral head and greater trochanter associated with sub-capital femoral neck fracture suggestive of bone neoplasm (? giant cell tumour > simple bone cyst). A bone biopsy was performed, and histopathological examination confirmed the diagnosis of fibrous dysplasia, with characteristic woven bone and fibrous stroma. In this case, after confirming the diagnosis, the patient was managed with total hip arthroplasty on the left side. Monostotic fibrous dysplasia is a rare benign bone disorder that can present with various clinical manifestations. Timely diagnosis through a combination of clinical, radiographic, and histopathological assessments is crucial. Management should be tailored to the patient's symptoms.

Abstract
Fibrous dysplasia (FD) is a rare, non-hereditary skeletal disorder characterized by its chronic course of non-neoplastic fibrous tissue buildup in place of healthy bone. A myriad of factors have been associated with its onset and progression. Perturbation of cell-cell signaling networks and response outputs leading to disrupted building blocks, incoherent multi-level organization, and loss of rigid structural motifs in mineralized tissues are factors that have been identified to participate in FD induction. In more recent years, novel insights into the unique biology of FD are transforming our understandings of its pathology, natural discourse of the disease, and treatment prospects. Herein, we built upon existing knowledge with recent findings to review clinical, etiologic, and histological features of FD and discussed known and potential mechanisms underlying FD manifestations. Subsequently, we ended on a note of optimism by highlighting emerging therapeutic approaches aimed at either halting or ameliorating disease progression.

Abstract
BACKGROUND Patients with dysplastic bone diseases, including fibrous dysplasia (FD), represent a particular challenge for placement of dental implants. This is due to structural bony changes that may compromise the bone blood supply and plasticity, thus potentially affecting the process of osseointegration. This case report describes a novel approach for dental-implant-based rehabilitation of the posterior maxilla affected by craniofacial fibrous dysplasia (CFD), with 7 years of treatment follow-up. CASE PRESENTATION A 35-year-old female patient was referred due to a suspected unidentified bone lesion affecting the left side of the maxilla. A clinical and radiographic diagnosis of fibrous dysplasia was confirmed through a wedge bone biopsy. Particulate bone substitute was packed into a box-shaped ostectomy area of the lesion in the affected maxillary alveolar ridge. This was followed by the placement of four implants 6 months post operation. The implants were successfully integrated, as confirmed by clinical examination over 7 years of follow up. CONCLUSION this treatment approach may be considered as a predictable and efficient treatment modality for dental implant rehabilitation in patients with a variety of fibro-osseous lesions, including fibrous dysplasia, which affect the alveolar bone.

Abstract
Fibrous dysplasia (FD) is a rare skeletal disorder characterized by abnormal fibro-osseous connective tissue replacing normal bone. Despite its benign behavior, craniofacial FD can cause morphological disfigurement, headache, and even blindness as a result of the produced mass effect. Surgical resection is recommended when the patient shows apparent clinical symptoms or aggravating facial asymmetry. Postoperative complications have been reported, such as hematoma, surgical site infection, abscess formation, resorption of the bone graft used for reconstruction, and recurrence. An aneurysmal bone cyst (ABC) is a rare benign bony lesion that can occur secondary to preexisting bone tumor. Secondary ABCs in craniofacial FD are extremely rare in the literature, accounting for less than 30, all of which are either case reports or series. We report an extremely rare case of symptomatic secondary ABC arising from craniofacial FD that had been misdiagnosed with abscess formation or recurrence and was surgically removed. Notably, 17 years elapsed between the primary surgery and the complication of secondary ABC. The patient underwent total removal of secondary ABC. After surgery, symptoms were relieved, with no recurrence observed during a 6-month follow-up.

Abstract
A total of 7% of all benign bone lesions are diagnosed as fibrous dysplasia (FD). The symptoms of FD of the jaw range from asymptomatic to dental anomalies, pain and facial asymmetry. Due to its resemblance to other fibro-osseous bone lesions, misdiagnosis often occurs and can lead to inadequate treatment. Particularly in the jaw, this lesion does not become quiescent during puberty, making fundamental knowledge about the diagnosis and treatment of FD crucial. Mutational analysis and nonsurgical approaches offer new diagnostic and therapeutic options. In this review, we examine the advances and the difficulties of the diagnosis and the various treatment modalities of FD of the jaw in order to capture the current scientific knowledge on this bone disease.

Abstract
McCune-Albright Syndrome (MAS) is a rare mosaic (post-zygotic) genetic disorder presenting with a broad continuum clinical spectrum. MAS arises from somatic, activating mutations in the GNAS gene, which induces a dysregulated Gsα-protein signaling in several tissues and an increased production of intracellular cyclic adenosine monophosphate (cAMP). Overall, MAS is a rare disorder affecting less than 1/100,000 children and, for this reason, data establishing genotype-phenotype correlations remain limited. Affected individuals clinically present with a variable combination of fibrous dysplasia of bone (FD), extra-skeletal manifestations (including cafeí-au-lait spots) and precocious puberty which might also be associated to broad hyperfunctioning endocrinopathies, and also gastrointestinal and cardiological involvement. Central nervous system (CNS) and eye involvement in MAS are among the less frequently described complications and remain largely uncharacterized. These rare complications mainly include neurodevelopmental abnormalities (e.g., delayed motor development, cognitive and language impairment), CNS anomalies (e.g., Chiari malformation type I) and a wide array of ophthalmological abnormalities often associated with vision loss. The pathophysiological mechanisms underlying abnormal neurological development have not been yet fully elucidated. The proposed mechanisms include a deleterious impact of chronically dysregulated Gsα-protein signaling on neurological function, or a secondary (damaging) effect of (antenatal and/or early postnatal) hypercortisolism on early pre- and post-natal CNS development. In this Review, we summarize the main neurological and ophthalmological features eventually associated with the MAS spectrum, also providing a detailed overview of the potential pathophysiological mechanisms underlying these clinical complications.

Abstract
OBJECTIVE To investigate the feasibility of endoscopic transnasal optic canal decompression (ETOCD) guided by a navigation surgical system (NSS) for vision recovery in patients with compressive optic neuropathy (CON) caused by craniofacial fibrous dysplasia (CFD), and to explore the underlying cause of visual impairment. METHODS All patients underwent unilateral NSS-guided ETOCD and were followed up periodically for at least six months. Paired sample t-test and Pearson correlation analyses were used to compare continuous variables of the visual outcomes at the final review. A histopathological test of abnormal bone specimens was performed postoperatively. RESULTS Thirty-four patients were finally included, and all surgeries were uneventful. The best corrected visual acuity (BCVA) (logMAR units) decreased from 1.29 ± 0.80 preoperatively to 0.97 ± 0.78 at the last follow-up (p = 0.0012), improving in 28 patients (82.35%). The absolute value of mean defect (MD) significantly decreased (p < 0.001). Color vision was impaired in 17 patients preoperatively and improved in 6 patients. BCVA at the last follow-up was significantly correlated with preoperative BCVA, onset time, preoperative retinal nerve fibril layer thickness, and MD (all p < 0.05). Among 34 patients, 26 had a blunt bony process near the anterior foot of the optic chiasm. Of the total patients, 73.53% patients experienced bony fiber recurrence 6 months or earlier after surgery without visual loss. CONCLUSION NSS-guided ETOCD appeared to be safe and effective for visual recovery in patients with CON due to CFD, and early surgical intervention was critical for long-term recovery. Unbalanced compression of the optic canal by the blunt bony process may be a major cause of visual impairment. LEVEL OF EVIDENCE 4 Laryngoscope, 2023.

Abstract
McCune-Albright syndrome (MAS) is a rare sporadic condition defined by the classic triad of fibrous dysplasia of bone, café au lait skin macules, and hyperfunctioning endocrinopathies. The molecular basis of MAS has been ascribed to the post-zygotic somatic gain-of-function mutations in the GNAS gene, which encodes the alpha subunit of G proteins, leading to constitutive activation of several G Protein-Coupled Receptors (GPCRs). The co-occurrence of two of the above-mentioned cardinal clinical manifestations sets the diagnosis at the clinical level. In this case report, we describe a 27-month-old girl who presented with gonadotropin-independent precocious puberty secondary to an estrogen-secreting ovarian cyst, a café au lait skin macule and growth hormone, and prolactin excess, and we provide an updated review of the scientific literature on the clinical features, diagnostic work-up, and therapeutic management of MAS.

Abstract
PURPOSE OF REVIEW This study aims to review diagnosis, potential complications, and clinical management in craniofacial fibrous dysplasia. RECENT FINDINGS Fibrous dysplasia (FD) is a rare mosaic disorder in which normal bone and marrow are replaced with expansile fibro-osseous lesions. Disease presents along a broad spectrum and may be associated with extraskeletal features as part of McCune-Albright syndrome (MAS). The craniofacial skeleton is one of the most commonly impacted areas in FD, and its functional and anatomical complexities create unique challenges for diagnosis and management. This review summarizes current approaches to diagnosis and management in FD/MAS, with emphasis on the clinical and therapeutic implications for the craniofacial skeleton.

Abstract
BACKGROUND Fibrous dysplasia (FD) is a localized bone disorder in which fibro-osseous tissue replaces the normal bone structure. Patients with craniofacial FD often present with gradual swelling, deformity, and compromised vision or hearing. We previously introduced "the core extirpation method," a novel surgical technique that is minimally invasive like traditional bone shaving but has longer-lasting effects. This study presents the long-term outcomes of our core extirpation method. METHODS We conducted a retrospective analysis of patients who underwent core extirpation for FD of the zygomaticomaxillary region from 2012 through 2021. Computed tomography (CT) scans were performed 6 to 12 months before the operation, immediately before and after the operation, and during follow-up visits. We performed all operations using the upper gingivobuccal approach, and we extirpated the core of the lesion while preserving the cortical structures of the zygoma and the maxilla to maintain symmetrical facial contour. RESULTS In 12 patients with lesions in the growth phase, anteroposterior/mediolateral (AP/ML) length discrepancies and the volume increased between preoperative and immediate postoperative CT scans. All patients' immediate postoperative AP/ML discrepancies were stable up to 12-17 months postoperatively. Postoperative volume showed continuous lesion growth; the median volume growth rate was 0.61 cc per month. CONCLUSION In this article, we present our experiences managing FD using the minimally invasive core extirpation technique, which entails small expected blood loss and can be performed as day surgery. It provides similar cosmetic outcomes as traditional bone shaving but with longer-lasting results. Although there are some limitations with the study's retrospective nature and small sample size, our 4-year follow-up results show promising results of the core extirpation method in well-indicated patients.

Abstract
Abstract
Background Craniofacial fibrous dysplasia (CFD) is an uncommon benign condition in which a bone is replaced by fibrous tissue. An adequate clinical characterization considering the number of affected bones and functional impairment is important to determine the most effective surgical intervention for its management. This study aims to present our institution's experience in the evaluation and management of CFD.
Methods This was a retrospective study that included patients with CFD managed at our institution. Data included demographic characteristics, afflicted bones, surgical procedures performed, and recurrence. Results are presented as mean and percentages. Recurrence-free years and association between the type of surgery and recurrence was evaluated.
Results Eighteen patients were included (11 females, 61%). The zygomatic, maxillary, and frontal bones were the most commonly affected with eight (18%) cases each. The most common procedure was bone burring, with 36 procedures. Recurrence was more prevalent after burring (58.3%) and occurred earlier than in the bone resection group (13 vs. 15 years, p > 0.05).
Conclusion Surgery continues to be the cornerstone of CFD treatment. Bone burring is effective for debulking and contouring but increases the risk for recurrence. An individualized approach should be tailored according to the anatomical location of the disease, type of CFD, behavior of the lesion, and accompanying clinical complaints.

Abstract
Bilateral optic disc swelling is a common finding but rarely associated with multiple cranial neuropathies. In this case, an 18-year-old man presented with subacute sequential hearing loss followed by subacute sequential visual loss. Clinical examination revealed bilateral optic disc swelling. Lumbar puncture revealed a normal opening pressure of 15 cmH2o. This case discusses a rare but important cause of bilateral optic disc swelling in the context of hearing loss, disequilibrium, and a normal CSF opening pressure. An overview of the literature is provided, and treatment options are discussed to guide further management of similar cases.

Abstract
Abdominal wall and spinal soft tissue findings are frequently encountered on CT or MR imaging of the abdomen and pelvis. Many of these entities have specific imaging findings, for which a definitive diagnosis can be made without the need for further work up. These abdominal wall and spinal findings may be diagnostically challenging for sub-specialized abdominal radiologists who are unfamiliar with their appearance and appropriate management. This review article describes and illustrates pathognomonic or characteristic abdominal wall and spinal pathologies, which reside outside the abdominopelvic cavity. The cases selected all have findings that allow a confident diagnosis without further imaging or intervention. The cases presented include myonecrosis, intramuscular abscess, myositis, iliopsoas bursitis, Morel-Lavallée lesion, hydrocele of canal of Nuck, Klippel Trenaunay Weber syndrome, neurofibroma with target sign, perineural cysts, filum terminale lipoma, calvarial bone flap, transverse rectus abdominis muscle (TRAM) flap, liposuction, and hidradenitis suppurativa, among others. Although not all-encompassing, this paper will help abdominal radiologists to accurately diagnose a variety of abdominal and pelvic extra-cavitary soft tissue pathologies by identifying key radiologic findings.

Abstract
Fibrous dysplasia in the bony walls of a paranasal sinus is a developmental tumour that is associated with a marked facial deformity. Delay in hospital presentation contributes to the destructive resection techniques employed and the management outcome. Our study looks at the factors for delay in hospital presentation and the management outcome by a retrospective review between January 1997 and December 2018. Of 43 children (M: F 1:1.2) with a mean age of 12 ± 1.75 years, the maxillary bones were mostly affected. All underwent surgical resection with good management outcomes except for maxillectomy. Tumour recurrence was noted in five and there was no mitotic cell at histology. The clinical symptoms of fibrous dysplasia vary in severity and age of onset, often with late hospital presentation already with complications. Health education is needed to reverse this trend.

A Novel Bone Contouring Technique Using Multiple Tangential Shaving for Conservative Management of Craniofacial Fibrous Dysplasia. J Craniofac Surg 2023; 34:45-52.

Abstract
This study aimed to propose a novel surgical technique, named multiple tangential shaving of bone contour, for the conservative management of craniofacial fibrous dysplasia. We retrospectively reviewed 17 patients who underwent conservative management of craniofacial fibrous dysplasia using multiple tangential shaving technique between July 2005 and December 2020. Demographics, tumor characteristics, and surgery-related factors were investigated. All patients underwent preoperative (T0) and postoperative computed tomography scans taken at least twice within 1 month for immediate assessment (T1) and at least 12 months postoperatively for long-term assessment (T2). Clinical outcomes, including tumor recurrence, perioperative complications, and physician measure of esthetic outcomes (Whitaker score), were investigated. This technique was applied for contouring of the zygomatic-maxillary and calvarial bone for patients aged between 16 and 60 years (mean age: 26 y). The mean±SD tumor volume reduction was 15.5±8.95 cm 3 , and the postoperative mean±SD tumor growth rate was 5.52±6.26% per year. Satisfactory outcome was obtained in terms of esthetics with a mean±SD Whitaker score of 1.41±0.62. Patients required a mean operation time of 1.67±0.43 hours and a mean number of shaving operations of 1.35±0.61 during the follow-up period. Five of 17 patients required reoperation because of the tumor recurrence (N=4) and to correct new-onset diplopia after surgery (N=1). In conclusion, the multiple tangential shaving technique allows an easy approach for conservative management of craniofacial fibrous dysplasia. An acceptable rate of tumor recurrence and esthetic outcomes can be obtained by selecting the appropriate candidate for a conservative approach.

Abstract
All endocrine glands are susceptible to neoplastic growth, yet the health consequences of these neoplasms differ between endocrine tissues. Pituitary neoplasms are highly prevalent and overwhelmingly benign, exhibiting a spectrum of diverse behaviors and impact on health. To understand the clinical biology of these common yet often innocuous neoplasms, we review pituitary physiology and adenoma epidemiology, pathophysiology, behavior, and clinical consequences. The anterior pituitary develops in response to a range of complex brain signals integrating with intrinsic ectodermal cell transcriptional events that together determine gland growth, cell type differentiation, and hormonal production, in turn maintaining optimal endocrine health. Pituitary adenomas occur in 10% of the population; however, the overwhelming majority remain harmless during life. Triggered by somatic or germline mutations, disease-causing adenomas manifest pathogenic mechanisms that disrupt intrapituitary signaling to promote benign cell proliferation associated with chromosomal instability. Cellular senescence acts as a mechanistic buffer protecting against malignant transformation, an extremely rare event. It is estimated that fewer than one-thousandth of all pituitary adenomas cause clinically significant disease. Adenomas variably and adversely affect morbidity and mortality depending on cell type, hormone secretory activity, and growth behavior. For most clinically apparent adenomas, multimodal therapy controlling hormone secretion and adenoma growth lead to improved quality of life and normalized mortality. The clinical biology of pituitary adenomas, and particularly their benign nature, stands in marked contrast to other tumors of the endocrine system, such as thyroid and neuroendocrine tumors.

Abstract
Fibrous dysplasia is a rare anomaly of bone tissue development, in which it is replaced by fibrocystic tissue. A clinical case of a patient with a craniofacial polyossal form of fibrous dysplasia is presented. At the age of 13, a child had a constant intense headache, which was accompanied by dizziness, tinnitus, cognitive impairment, deformity of the frontal region and lower jaw on the right, local pigmentation in the neck and face (coffee-and-milk-like stains). Brain tomography and osteoscintigraphy visualized a volumetric formation in the right half of the skull bones, in which fibrotic dysplasia was revealed during histological examination.Conclusion. To establish this diagnosis, a combination of pain syndrome with deformation of the facial part of the skull and histological examination is important.

Abstract
Fibrous dysplasia (FD) is a rare benign disease that replaces a normal bone with abnormal fibrous and weak osseous tissue. It is usually detected in childhood and rarely occurs in old age. Although the disease is known to be caused by a genetic mutation, only a single case of FD secondary to surgery is reported in the literature. We report a case of monostotic FD of the maxillary sinus in a 70-year-old Asian woman who presented with incidental calcific lesion in the maxillary sinus on a brain computed tomography scan. At 32 months prior to presentation, the patient had undergone an endoscopic sinus surgery for a fungal ball of the same sinus. The lesion was removed by endoscopic surgery, and the histopathological evidence was consistent with FD. To the best of our knowledge, this is the second case of a postsurgical craniofacial FD, and a rare case that occurred in old age.

Abstract
PURPOSE Fibrous dysplasia (FD) is a benign condition, which is characterized by the replacement of normal bone with fibrous tissue and the deposition of woven bone in an irregular manner. Surgical resection, careful corrective osteotomies as debulking, and recontouring procedures are frequently performed, but can be complicated by postoperative regrowth of the lesion. The main aim of this study was to introduce a computer-guided technique for a predetermined technique of bone contouring of craniofacial FD involving the facial bones. METHODS This case report was conducted on an 18-year-old girl complaining of unilateral craniofacial dysplasia. Upon clinical examination and radiographic examination, a customized computer-generated bone contouring guide was designed using virtual surgical software for accurate contouring of excess bone in the cranial vault and frontal bone. This guide was virtually designed after importing the multislice computerized tomography scans into the virtual surgical planning software. It was generated based on the mirroring option of the unaffected normal side along the median sagittal plane. In the surgery, the guide was seated in place and 5 mm implant drills were inserted through the guide depth holes. Bone removal was made using surgical burs connecting the guiding depth holes. RESULTS At the end of the follow-up, the patient showed acceptance of her external appearance with no signs of infection or dehiscence. CONCLUSION This patient-specific cutting guide shows a promising solution for preplanned bone removal in cases with unilateral craniofacial FD.

Abstract
Fibrous dysplasia, specially of anterior and central skull base region, is a rare disorder. This article discusses about our experience in this pathology. A tertiary care institute based retrospective type study was conducted over a period of 12 years. Demographics, radiology, intraoperative details, pathology and follow up were taken into consideration and the data was analysed. Sixteen patients with complaints of proptosis, diplopia, nasal obstruction and/or facial deformity, underwent endoscopic sinus surgery. Subtotal resection was done in 5 patients. Ethmoid bone involvement was seen in 12 patients. Post operatively, diplopia persisted in one patient and one patient had epistaxis. All patients were followed up for 2-10 years with no other complications reported. Anterior and central skull base involvement is rare in fibrous dysplasia. However, it can be removed effectively by endoscopic approach. Overall safety of patient has more concern rather than complete removal of disease.

Abstract
INTRODUCTION Fibrous dysplasia (FD) is a benign, idiopathic skeletal disorder, in which the normal bone and marrow are replaced by fibrous tissue and immature woven bone. The authors aim to analyze the long-term results of patients diagnosed with FD of the paranasal sinuses via imaging or surgical biopsy. METHODS The authors retrospectively enrolled 21 patients with FD of the paranasal sinuses from 2006 to 2021. RESULTS The mean age at the time of diagnosis of FD of the paranasal sinuses was very high at 45.9 years. The most common site ofoccurrence was the sphenoid sinus (71.4%). During the mean follow-up period of 52.8 months, there was no significant change in the size of FD of the paranasal sinuses, and there was no worsening of symptoms or complications. Endoscopic sinus surgery was performed in 16 patients (76.2%), of which 13 underwent only biopsy and 3 underwent partial resection. CONCLUSIONS The most common site of FD of the paranasal sinuses was the sphenoid sinus, and the age at diagnosis was higher thanthat of patients with FD at other sites. Observation with serial radiologic examinations is recommended for asymptomatic FD of the para-nasal sinuses.

Abstract
Fibrous dysplasia (FD) is a fibrous lesion of immature bone, with an incidence of 10–20% in the head and neck region. Most cases are monostotic, but when a lesion occurs on the maxillofacial region and spreads to the surrounding bone, it is classified as polyostotic, despite its localized occurrence. In some cases, surgical intervention is required to improve the cosmetic or functional disturbance of a FD in the maxillofacial region, but it is necessary to confirm symmetry of the maxillofacial region in real time, and a surgical support system is required to compensate. Furthermore, prosthetic intervention is considered when postoperative acquired defects occur or further cosmetic or occlusal function improvement is needed. A comprehensive approach by an oral surgeon and a maxillofacial prosthodontist is necessary for the successful treatment and rehabilitation of such patients. In this article, we describe the case of a craniomaxillofacial FD patient with facial asymmetry and denture incompatibility with improved quality of life measures by integrating surgical treatment using a navigation system and postoperative prosthetic rehabilitation. We also discuss recent diagnostic methods and treatment strategies for craniomaxillofacial FD in the literature.

Abstract
BACKGROUND Fibrous dysplasia (FD) is an uncommon bone disease characterized by the replacement of normal bone architecture with abnormal fibro-osseous connective tissue. Here, we discuss 2 cases of craniofacial FD, with malignant sarcomatous degeneration - a rare and morbid complication of the disease. CASE HISTORY Two cases of craniofacial FD with malignant degeneration are presented. In the first, a 68-year-old male with a history of FD presented with acutely worsening left-sided facial pain and V2 and V3 hypoesthesia. Imaging findings suggested a large infratemporal fossa mass with biopsy demonstrating sarcomatous degeneration. Radical craniofacial resection achieved a gross total resection with likely microscopic disease. The patient was unable to tolerate adjuvant chemotherapy or radiation and succumbed to his disease 13 months following surgery.In the second case, a 36-year-old male with McCune-Albright Syndrome and craniofacial FD presented with acutely worsening left-sided headaches and midface hypoesthesia. Imaging revealed a heterogenous and expansile lesion with erosive changes in the left nasal cavity and infratemporal fossa. Pathology was suggestive of low grade sarcomatous degeneration. Given the extensive involvement of the skull base, the tumor was deemed unresectable, and the patient soon died following initiation of chemotherapy. CLINICAL RELEVANCE Malignant sarcomatous transformation is a rare and challenging complication of craniofacial FD. Indolent onset, advanced spread at time of presentation, and close relationship with vital neurovascular structures are all hurdles for the treating clinician. The entity poses a diagnostic dilemma, as pathological analysis can be equivocal and may mimic nonmalignant processes, such as locally aggressive FD.

Abstract
A 48-year-old man visited the emergency department of our hospital with swelling of the left upper and lower eyelids from the day before. On the first examination, he had severe swelling of the left upper and lower eyelids, proptosis, and chemosis. Left intraocular pressure was 33 mmHg. Computed tomographic images showed an orbital abscess in the anterosuperolateral orbital space, maxillary and ethmoidal sinusitis, and dacryocystitis. The orbital abscess was not contiguous to maxillary and ethmoidal sinusitis and dacryocystitis. Ground-glass appearance was seen in the frontal, maxillary, and ethmoid bones, and most of the space of the frontal sinus was obliterated due to the expansion of the frontal bone. Emergent drainage of orbital abscess, dacryocystorhinostomy, and endoscopic sinus surgery were performed under general anesthesia. Intravenous tazobactam/piperacillin was administered. A culture test of the sinus pus and orbital abscess showed growth of Streptococcus intermedius (2+). At one month postoperatively, there was no recurrence of orbital abscess, paranasal sinusitis, and dacryocystitis.

Abstract
Fibrous dysplasia (FD) is a rare, benign, chronic, slowly progressive bone disorder characterized by the replacement of normal bone and bone marrow by fibrous tissue, leading to deformity, pain and functional impairment. It was considered a disease of unknown etiology, uncertain pathogenesis and diverse histopathology. It was later discovered that was caused by a non-heritable activating mutation in the á-subunit gene of the stimulatory G-protein coding gene. Temporal bone involvement is the least frequently reported type, especially in children. The purpose of the current manuscript was to report a rare case of fibrous dysplasia of the left temporal bone of a 17-year-old child who came to the emergency room of our hospital with otalgia and progressive hearing loss on the left ear.

Abstract
BACKGROUND Craniofacial fibrous dysplasia (CFD) typically occurs in the facial bones and anterior cranial vault and can produce both disfigurement and functional limitations for patients disfigurement. Treatment consists of reducing the abnormal bone. Bone contouring can become challenging when the exposure does not extend to the corresponding normal contralateral structures for comparison or when normal landmarks are not available, which may compromise the overall aesthetic outcome. We describe a technique using dynamic mirroring to accurately contour the involved part of the cranium in a case of giant CFD. OBSERVATIONS A 49-year-old male presented with a giant deforming fibrous dysplasia of the right mastoid and parieto-temporo-occiput that was causing functional limitations due to the size of the bony mass. This was managed with multidisciplinary bony reduction. Several neurovascular structures were in proximity to the areas of planned drilling of the expansile lesion, and dynamic mirroring of the uninvolved left skull was utilized to maximize safety and symmetry of reduction. High-speed drilling of the right occipital bone was performed until the navigation system alerted the surgeon that symmetric depth had been achieved. There were no complications from the procedure and this technique maximized the limits of symmetric reduction without significantly increasing surgical complexity or duration. LESSONS Dynamic mirroring of bony structures in the posterior cranium is not commonly employed in neurosurgical practice. This technique may help improve the aesthetic outcomes of bony reduction in craniofacial dysplasia and a variety of similarly managed bony lesions, contour cranioplasties, and in unilateral craniosynostosis surgery.

Abstract
OBJECTIVE Current management of fibrous dysplasia (FD) involving the paranasal sinuses and the adjacent skull base is currently controversial. This study aims to present our experience in the management strategy of FD that involves the paranasal sinuses and the adjacent skull base. METHODS Twenty three patients from 2006 to 2019 with monostotic fibrous dysplasia (MFD), polyostotic fibrous dysplasia (PFD), or McCune-Albright syndrome (MAS) involving the paranasal sinuses and the adjacent skull base were retrospectively reviewed. This study series was divided into 3 groups based on management strategies: the observation group, the surgery group, and the optic nerve decompression group. RESULTS The observation group included 9 patients with asymptomatic MFD with stable condition during the follow-up period of 15 to 164 months. The surgery group included 10 symptomatic patients with MFD who had personalized endoscopic endonasal surgery. The symptoms of the patients were relieved after surgery. The optic nerve decompression group included 4 patients with visual loss, who underwent endonasal endoscopic optic nerve decompression (EOND) with the aid of image-guided navigation. Their vision improved after surgery. CONCLUSIONS Clinical observation and periodic computed tomography (CT) scan are adopted for asymptomatic patients. Surgery is indicated in symptomatic patients. Optic nerve decompression is recommended as soon as possible if the patient has visual loss, whereas prophylactic decompression is not recommended if the optic nerve is encroached by FD without visual loss. Navigation plays an important role in endoscopic surgery involving the paranasal sinuses and the adjacent skull base, especially in FD resection and optic nerve decompression.

Abstract
Background Craniopharyngioma (CP) and cranial fibrous dysplasia (CFD) are rare embryonic benign cranial diseases that most commonly present during childhood or adolescence. The coexistence of CP and CFD is extremely rare and has not yet been reported. Methods We retrospectively reviewed the data of five patients with concomitant CP and CFD treated at Beijing Tiantan Hospital from January 2003 to January 2021 and summarized their clinicopathological features, treatment modalities, and outcomes. We also performed a comprehensive literature review, tested the patients for characteristic GNAS gene mutations related to CFD, and tested the CP specimens for corresponding Gsα protein to explore the potential connection leading to the coexistence of CP and CFD. Results The cohort comprised four men and one woman (median age, 39 years). The symptoms mainly included headache, dizziness, fatigue, polyuria/polydipsia, hypogonadism, and blurred vision. CFD most commonly involved the sphenoid bone (n = 4). Four patients underwent surgery to remove the CP (one trans-sphenoidal and three transcranial resections); complete and subtotal resection were achieved in two patients, respectively. The tumor subtype was adamantinomatous in three patients and unknown in one. The common postoperative complications were panhypopituitarism, diabetes insipidus, and hypothyroidism. The mean follow-up duration was 57.2 months. Two patients required postoperative hormone replacement therapy. Three patients underwent genetic study of the tumor specimens; GNAS mutations were not detected, but these patients were positive for Gsα protein. Conclusions Although a definite causative relationship has not been proved, the coexistence of CP and CFD means that potential interplay or an atypical fibrous dysplasia course as uncommon manifestations of CP cannot be excluded. It is more challenging to initiate prompt diagnosis and appropriate treatment for concomitant CP and CFD than for solitary CP because of skull base deformations. Current management strategies are aimed at surgical treating the CP and regularly monitoring the CFD.

Abstract
Patients with fibrous dysplasia (FD) often present with craniofacial lesions that affect the trigeminal nerve system. Debilitating pain, headache, and migraine are frequently experienced by FD patients with poor prognosis, while some individuals with similar bone lesions are asymptomatic. The clinical and biological factors that contribute to the etiopathogenesis of pain in craniofacial FD are largely unknown. We present two adult females with comparable craniofacial FD lesion size and location, as measured by 18F-sodium fluoride positron emission tomography/computed tomography (PET/CT), yet their respective pain phenotypes differed significantly. Over 4 weeks, the average pain reported by Patient A was 0.4/0–10 scale. Patient B reported average pain of 7.8/0–10 scale distributed across the entire skull and left facial region. Patient B did not experience pain relief from analgesics or more aggressive treatments (denosumab). In both patients, evaluation of trigeminal nerve divisions (V1, V2, and V3) with CT and magnetic resonance imaging (MRI) revealed nerve compression and displacement with more involvement of the left trigeminal branches relative to the right. First-time employment of diffusion MRI and tractography suggested reduced apparent fiber density within the cisternal segment of the trigeminal nerve, particularly for Patient B and in the left hemisphere. These cases highlight heterogeneous clinical presentation and neurobiological properties in craniofacial FD and also, the disconnect between peripheral pathology and pain severity. We hypothesize that a detailed phenotypic characterization of patients that incorporates an advanced imaging approach probing the trigeminal system may provide enhanced insights into the variable experiences with pain in craniofacial FD.

Abstract
ABSTRACT Both congenital cystic adenomatoid malformation (CCAM) and lambdoid craniosynostosis are exceedingly rare, with estimated incidences of around 1 in 30,000 live births for each. Herein, we present a case of a patient with prenatally diagnosed CCAM requiring 4 doses of prenatal steroids and ultimately thoracotomy with right lower lobectomy. The operation was uncomplicated, and genome-wide analysis of SNPs revealed no pathologic abnormalities. Development was normal until head shape changes were noted at 5 months of age at which point evaluation by a craniofacial surgeon and 3D CT imaging revealed left-sided lambdoid craniosynostosis. The patient underwent uncomplicated posterior and middle vault expansion and remodeling of his lambdoid synostosis at 11 months of age. This paper explores the etiopathogenesis of CCAM and lambdoid craniosynostosis in an attempt to identify common pathways involved in the development of these exceedingly rare diseases which, to date, have not been described in the peer-reviewed literature.

Abstract
Background: Cranial or craniofacial fibrous dysplasia (CFD) is a rare entity which most often presents with either incidental finding or with pain/cosmetic disfigurement or visual/hearing problems. Multidisciplinary treatment with close follow-up or medical management/surgery is options. Management of these lesions can often give satisfying results. There is a dearth of neurosurgical literature on this subject matter. Our objective was to review the clinical symptomatology and outcome of CFD patients managed in our institution. Methods: This is a retrospective observational study of CFD patients managed in our institution over a period of 5 years. Clinical and radiological data were collected from departmental database. Outcomes were evaluated immediately and on 1–4 years follow-up. Results: A total of 21 patients were managed over a period of 5 years with age ranging from 12 to 55 years and symptoms of cosmetic issues or visual disturbance. Preoperative computed tomography scan with 3D reconstruction with bone window was done in all patients. In most of the patients (16/20), immediate reconstruction was done following excision. Five patients were managed conservatively. Follow-up was obtained over a period ranging from 1 to 4 years and all (except one) patients are doing well. Only one patient had permanent visual impairment in spite of early intervention. Conclusion: Craniofacial dysplasia has various modalities of management. Careful selection of patients for surgical or conservative management is feasible with good results both in short and long term.

Abstract
Fibrous dysplasia (FD) is a developmental pathology of the bones in which normal bone is replaced by fibrous tissue and immature bone. It can affect single bone (monostotic) or multiple bones (polyostotic), sporadically or in association with McCune-Albright syndrome, Jaffe-Lichtenstein syndrome, or Mazabraud syndrome. When multiple bones in the craniofacial region are affected, the term "craniofacial FD" is used. Nonspecific cystic degeneration occurring in FD of the jaws has rarely been reported in the literature. Here, we present a 52-year-old male patient who reported with a longstanding gradual expansion of the mandible unilaterally. Investigations revealed the presence of mixed radiolucent radioopaque appearance in the mandible and dense sclerotic multiple craniofacial bones. In addition, a lytic lesion in the mandible was appreciated. Histopathological examination of the mandible confirmed the diagnosis of FD with nonspecific cystic degeneration.

Abstract
Fibrous dysplasia (FD) is a progressive and benign osteodystrophic disease where cranial bones are most commonly affected. In this case report, we present a 27-year-old patient with previous diagnosis of FD who was referred to our clinic with sudden loss of visual acuity and color discrimination. Examination of the right eye was normal, whereas visual acuity on the left eye was 6/9 and color vision (CV) with Ishihara test plates was 9/12. The visual field (VF) demonstrated a peripheral concentric defect on the left eye. As visual acuity in the left eye decreased to 6/30 and computed tomography imaging of the brain and orbit showed optic nerve compression by immature bony structures, optic nerve decompression was recommended with the diagnosis of compressive optic neuropathy. Endoscopic transnasal orbital and optic canal decompression was performed. At the postoperative course, visual acuity on the left eye turned to 6/6, CV was 12/12, and VF improved markedly. In subjects with craniofacial FD, a multidisciplinary approach is important. If there is evidence of compressive optic neuropathy, surgery should be performed.

Abstract
McCune-Albright-Braitsev Syndrome (MAB syndrome) is a very rare multisystem disease manifested by fibrous bone dysplasia, coffee-and-milk colored spots, hyperfunction of various endocrine glands and a number of pathologies of other body systems. We present a description of a clinical case of a severe progressive course of MAB Syndrome in a nine-year-old girl. With this diagnosis, the girl is observation of the girl began when she was 2.5 years old, when spots of coffee-and-milk, polyosseous fibrous dysplasia, peripheral premature sexual development against a backdrop of estrogen--secreting ovarian cysts, multinodular goiter were detected. In the process of dynamic observation, it was noted that the child's active growth stopped against a backdrop of deformities of the skeletal system with multiple repeated fractures of the extremities; progression of skull deformity with stenosis of the optic nerve canals and deterioration of visual acuity; development of STH hypersecretion, hypophosphatemic rickets, tachycardia. Appropriate suppressive / replacement therapy was prescribed for each of the endocrine dysfunctions. The article presents algorithms for examining a girl in dynamics, criteria for choosing a component-wise management tactics and a discussion of the features of the course of all manifestations of the Syndrome.

Abstract
OBJECTIVE In order to reduce the possibility of accidental injury to neurovascular and important tissues, this research conduct preoperative design and intraoperative guidance for fibrous dysplasia through augmented reality technology. METHODS Five patients with fibrous dysplasia were selected for three-dimensional (3D) computed tomography (CT) scan and 3D model was reconstructed. Considering the navigation plan was comprehensively, the guide plate (composed of card groove, connector, and fixator) was designed and 3D printed. Three-dimensional software was used to unify the coordinates of the surgical plan and the guide plate, and the relative position was fixed. Then, the virtual and real overlapping registration is completed on the physical model. Pattern recognition technology is used to identify pre-defined markers in the video images before operation. Finally, the registration results are superimposed into the surgical field of vision to guide and remind surgeons. RESULTS In this study, the navigation based on augmented reality technology was used in the surgical treatment of 5 cases patients with fibrous dysplasia. The 3D navigation information was displayed in real time in the operative field. The operation was accurate and the postoperative effect was good. CONCLUSIONS This paper introduces an effective visual navigation surgical method in treatment with fibrous dysplasia. The augmented-reality based navigation system achieves individualized precise treatment by displaying 3D navigation directly in the surgical field. It is an effective auxiliary method for future research on craniofacial surgery.

Abstract
BACKGROUND Fibrous dysplasia (FD) is a developmental hamartomatous bone disease characterized by a blend of fibrous and osseous entities. Though rarely malignant, the tumor can vary from being small and asymptomatic, to a fairly large sized lesion, progressing gradually, compromising occlusion and facial esthetics. Treatment approach depends on the stage of skeletal maturity. It primarily involves surgical management for stabilizing the disease process. Post-surgical comprehensive dental treatment is necessary for restoring form and function of the jaws and teeth. This article describes comprehensive orthodontic management of severe malocclusion in a surgically operated case of FD maxilla.
CASE SUMMARY A 19-year female presented with a chief complaint of excessive gingival display when smiling. Dental history included swelling of gums around the upper right front teeth, diagnosed at the age of 15 as FD of the right anterior maxillary segment and treated with surgical recontouring of the dysplastic bone. The clinical and radiological examinations showed adequate post-surgical healing. The surgically treated dysplastic area presented with right canting of the maxillary anterior occlusal plane. The maxillary teeth were torqued palatally, with the root of the right maxillary canine exposed clinically. We discuss sequential management of the associated malocclusion with comprehensive fixed orthodontics, along with special precautions taken to prevent reactivation of the quiescent and healed lesion.
CONCLUSION The adequate healing of fibro-dysplastic bone post-surgery must be allowed before initiating orthodontic tooth movement in the dysplastic bone. Periodic follow-ups are needed to monitor stability of occlusion and any relapse of the lesion.

Abstract
Monostotic fibrous dysplasia is a benign asymptomatic lesion that affects only one bone, which is replaced by amorphous connective tissue. Clinically there is an increase in the volume of the affected area, which is observed by imaging as a radiopaque area with diffuse non-corticalized limits capable of expanding to neighboring structures, and it is histologically evidenced as "resembling Chinese characters". The lesion is seen as a radiopaque image with diffuse borders in conventional or digital radiography, while cone beam computed tomography identifies the exact location and extension of an isodense, mixed or hyperdense image of non-corticalized edges. Magnetic resonance imaging is also used when the lesion involves soft tissues or nerves, and bone scintigraphy is performed in order to systemically observe bone quality. The objective of this article was to describe the new technologies in oral radiology for the diagnosis of monostotic fibrous dysplasia and the importance of the current imaging methods in achieving an adequate diagnosis. These techniques range from conventional radiography to bone scans, which provide images of higher quality, clarity and better precision with less invasive techniques to the patient. This review of the literature helps to expand the knowledge of dental professionals in relation to the clinical and imaging characteristics of monostotic fibrous dysplasia.

Abstract
BACKGROUND Although pathology in the maxillary and mandibular bones is rare in young patients, the differential diagnosis is broad. The World Health Organization (WHO) updated its classification of maxillofacial bone pathology in 2017. Using these updated guidelines, a systematic review of common maxillofacial bone lesions in the pediatric population was performed. METHODS A PubMed search was conducted capturing English language articles from inception to July 2020. Thirty-one articles were identified that described the frequency of maxillofacial bone pathology. Data were extracted and organized using the WHO 2017 classification of odontogenic and maxillofacial bone tumors. Prevalence data were analyzed among diagnostic categories and geographical regions. The SAS version 9.4 was used to complete statistical analyses. RESULTS The articles included patients from birth to a maximum age of 14 to 19 years. The most common odontogenic cysts included radicular cyst (42.7%) and dentigerous cyst (39.0%) followed by odontogenic keratocyst (15.0%). Among odontogenic bone tumors, odontoma (49.3%) was most common followed by ameloblastoma (29.1%). The most common nonodontogenic bone tumor was fibrous dysplasia (42.4%), and the most common malignant bone tumor was osteosarcoma (75.0%). Significant variations were found by geographic region, with dentigerous cyst more common than radicular cyst, and ameloblastoma more common than odontoma in African and Asian countries (P < 0.0001). CONCLUSIONS This systematic review uses the WHO 2017 guidelines to classify common odontogenic and nonodontogenic maxillofacial bone lesions around the world. Pathogenesis, presentation, and available treatment options for the most common maxillofacial bone lesions are reviewed.
