Abstract
PURPOSE Our center adopted posterior vault distraction osteogenesis (PVDO) as a first-line intervention for cranial expansion in syndromic craniosynostosis in 2008, and we have a growing cohort of patients undergoing transcranial midface advancement who have not had prior fronto-orbital advancement (FOA). The purpose of this study was to evaluate whether a history of FOA influences the risk profile of transcranial midface advancement in patients with syndromic craniosynostosis. METHODS Patients undergoing transcranial fronto-facial advancement from 2000 to 2022 were retrospectively divided into cohorts based on preceding history of fronto-orbital advancement (FOA- and FOA+). Perioperative outcomes including operative time, length of stay, intraoperative dural injury, and complications (Clavien-Dindo score) were compared between groups with appropriate statistics. RESULTS Thirty-eight patients were included (15 in FOA- group and 23 in FOA+ group). The overall complication rate was 47% (10% minor, 37% major). Compared to the FOA- group, the FOA+ group had a higher incidence of dural tears (65% v 20%, p = 0.006) and major complications (48% v 13%, p = 0.028). These findings were recapitulated in multivariate logistic regression controlling for other predictors. CONCLUSIONS Prior FOA is associated with increased rates of major complications and dural tears in patients with syndromic craniosynostosis undergoing fronto-facial surgery. Options for cranial vault expansion that avoid the frontal region, such as PVDO, may favorably alter the risk profile of fronto-facial advancement.

Abstract
ABSTRACT Isolated metopic synostosis presents with a range of severity, from a palpable ridge as the sole presenting feature to a constellation of features resulting in trigonocephaly. At our unit, patients on the moderate to severe end of the phenotypic spectrum of trigonocephaly are offered fronto-orbital advancement and remodeling. The authors present our series of trigonocephaly patients who have undergone surgical correction. From January 2000 to January 2020, the authors operated on 231 patients with trigonocephaly. The average age at surgery was 18 months, with an average follow-up of 77.4 months. Seventy-nine percent of patients had no comorbidity. Ten percent of patients sustained a dural tear with no long-term consequences. The total early complication rate was 12.1%. The most common early complications were wound infection and wound dehiscence at 7.4% and 3.9% respectively. The total reoperation rate was 6.5%. The introduction of infection prevention and control measures over the 2 decades at our unit reduced the reoperation rate to 1.1%. The most common late complication was temporal recession in 20.8% of patients, none of whom required aesthetic correction. The recurrence rate of a metopic ridge was 2.3% with no patients requiring further surgery. None of our patients required calvarial remodeling for raised intracranial pressure after the primary fronto-orbital advancement and remodeling. There were no life-threatening complications or mortalities in our cohort. The authors present recommendations which include an infection control care bundle, cessation of surgical drains, and practice adjustments to reduce risks of infection and risk of requiring further calvarial remodelling for raised intracranial pressure.

Abstract
Paediatric craniomaxillofacial (CMF) surgery requires a multidisciplinary team approach to ensure the optimal and holistic management of children with craniofacial deformities. The aim of this retrospective study was to analyse the complications following functional interventions among 34 CMF deformity patients in a single multidisciplinary craniofacial centre. Electronic data including patient demographic characteristics and clinical entry were analysed. Inclusion criteria were all paediatric patients with CMF deformities who underwent various functional interventions. A total of 64 interventions (48 intermediate and 16 definitive) were conducted. Based on the Sharma classification of complications, 20.3% were type I, 4.7% were type II, 1.6% were type III, and 4.7% were type IV . Most complications were type I, which included local infection (3.1%) and premature opening of tarsorrhaphy (3.1%). More serious complications (types III and IV) included temporary visual loss (1.6%) and intraoperative haemorrhage (1.6%). Although a low complication rate was observed in intermediate interventions, a higher complication rate was observed in more complex definitive interventions such as monobloc distraction osteogenesis. Although most complications were manageable, effective prevention remains mandatory, as serious complications may lead to permanent damage and mortality. This analysis highlights the importance of a multidisciplinary team approach to optimize the outcomes in CMF patient management.

Topical Vancomycin for Surgical Prophylaxis in Pediatric Craniofacial Surgeries. J Craniofac Surg 2019; 30:2163-2167.

Abstract
Topical vancomycin has been demonstrated to be safe and effective for reducing surgical site infections (SSIs) following spine surgery in both adults and children, however, there are no studies of its efficacy in reducing SSIs in craniofacial surgery. The SSIs are one of the most common complications following craniofacial surgery. The complexity of craniofacial procedures, use of grafts and implants, long operative durations and larger surgical wounds all contribute to the heightened risk of SSIs in pediatric craniofacial cases. A retrospective review of all open and endoscopic pediatric craniofacial procedures performed between May 2014 and December 2017 at a single children's hospital was conducted to examine SSI rates between patients receiving topical vancomycin and a historical control group. The treatment group received topical vancomycin irrigation before wound closure. An ad-hoc cost analysis was performed to determine the cost-savings associated with topical vancomycin use. A total of 132 craniofacial procedures were performed during the study period, with 50 cases in the control group and 82 cases in the vancomycin group. Overall, SSI rate was 3.03%. Use of topical vancomycin irrigation led to a significant reduction in SSIs (4/50 SSI or 8.0% in control group vs 0/82 or 0% in vancomycin group, P = 0.04). No adverse events were observed with topical vancomycin use. The potential cost-savings associated with the use of topical vancomycin as SSI prophylaxis in this study was $102,152. Addition of topical vancomycin irrigation as routine surgical infection prophylaxis can be an effective and low-cost method for reducing SSI in pediatric craniofacial surgery.

Abstract
Removal of the fronto-orbital bandeau is one of the most critical components for procedures designed to correct anomalies of the craniofacial skeleton and remodel the anterior calvarial vault. It is also used to improve exposure of the anterior cranial fossa. It is arguably one of the more difficult portions of some craniofacial procedures. While the technique for fronto-orbito-sphenoid osteotomy has been frequently described, it has only been minimally detailed. Separation of bone in this region remains challenging due to the bone thickness, adjacent vital structures, and limited direct visibility. The present paper describes the anatomy of this particular region, which the authors have termed the "triple point", to facilitate successful osteotomy and avoid potential injury.

Abstract
Within the diagnosis "craniosynostosis," there is a subset of patients who present with isolated, nonsyndromic, single-suture involvement. This study evaluates perioperative complications in this specific subset of patients over 4 decades at a single institution. To do so, we performed a retrospective review on consecutive patients undergoing correction of single-suture synostosis from May 1977 to January 2013 at a tertiary pediatric craniofacial center. Demographic information, operative details, and perioperative course were collected. Complications were categorized as either major or minor. A χ(2) test and Fisher exact test were used to compare all categorical variables. Continuous variables were analyzed using Wilcoxon rank-sum and Kruskal-Wallis tests.Seven hundred forty-six patients underwent surgical correction of nonsyndromic craniosynostosis. Of these, there were 307 (41.2%) sagittal, 201 (26.9%) metopic, and 238 (31.9%) unicoronal. Thirty-four patients had complications (4.6%). Eight were considered major (1.1%), including one postoperative mortality in a patient with hypoplastic left-sided heart syndrome. Minor complications occurred in 26 patients (3.5%) and included subgaleal hematoma (n = 3), seroma (n = 4), and superficial wound infection (n = 5). Metopic and sagittal suture involvement was significantly associated with a higher complication rate (P = 0.04). A child with isolated single suture synostosis and any comorbidity had a significantly greater risk of any complication (P < 0.001; odds ratio, 3.8) and specifically an increased risk of major complication (P = 0.031; odds ratio, 6.0). Subclassification of patients by time period yielded no statistically significant changes in perioperative morbidity. To conclude, these data allow us to counsel families more accurately with regard to morbidity and mortality and may potentially serve as a benchmark for future quality improvement work.

Abstract
LEARNING OBJECTIVES After studying this article, the participant should be able to: (1) Make the appropriate diagnosis for each of the single-sutural synostoses, based on the physical examination. (2) Explain the functional concerns associated with these synostoses and why surgical correction is indicated. (3) Distinguish between the different types of surgical corrections available, the timing for these various interventions, and in what ways these treatments achieve overall management objectives. (4) Identify the basic goals involved in caring for the syndromic synostoses. SUMMARY This article provides an overview of the diagnosis and management of infants with craniosynostosis. This review also incorporates some of the treatment philosophies followed at The Craniofacial Center in Dallas, but is not intended to be an exhaustive treatise on the subject. It is designed to serve as a reference point for further in-depth study by review of the reference articles presented. This information base is then used for self-assessment and benchmarking in parts of the Maintenance of Certification process of the American Board of Plastic Surgery.

Abstract
Craniofacial surgery is one of the newer subspecialties of plastic surgery and owes its birth to the pioneering work of Paul Tessier in the late sixties. Since then this challenging specialty work has been taken up by many centres around the word including India. Initial reports in late eighties and early nineties showed morbidity and mortality ranging from 1.6% to 4.3%. However over past few decades, with improved instrumentations, safer anaesthesia and cumulative experience of surgeons the morbidity and mortality has been brought down to as low as 0.1% in many centres in USA. In our centre at Post-graduate Institute, Chandigarh, the mortality rate is about 0.8% (4 out of 480 cases). The learning curve in this surgery is rather steep but with experience and a well-coordinated team work, results in this complex subspecialty can be improved. The infection is a major cause for worry but can be easily prevented by sound surgical principles and placing a vascularised tissue barrier between the extradural space and the nasopharynx/sinus mucosa.

Abstract
In syndromic craniosynostosis, the relation between the supraorbital area and the frontal bone is not good, and it is not possible to reform this area with 1-block advancement. To avoid this problem, the frontal bone is separated from the fronto-orbital bandeau, each is reshaped and remodeled separately, and then both are reattached. The retrusion of the midface, especially in syndromic craniosynostosis, is usually greater than that of cranial bones, so the technique usually separating the midface from the cranium is Le Fort III osteotomy, which allows differential distraction of each part. In this procedure, the cranial and midfacial bones are advanced simultaneously and differentially, both to the planned extent, in a single-stage operation, using rigid external distractor II, correcting exorbitism, respiratory embarrassment, and cranial structures and avoiding eye complications in the future. This procedure was used, with a follow-up, in 10 patients with syndromic craniosynostosis from 2 to 5 years.

Abstract
BACKGROUND The adaptation of distraction osteogenesis (DO) to the midface and cranium in the 1990s and the advancements that followed at the turn of the century resulted in a shift of paradigm in craniofacial surgery. Because skeletal advancement was not sudden anymore, but incremental, the monobloc advancement became safer to perform. Because bone was generated in the distraction gap, bone grafts were no longer needed, and younger patients could benefit from craniofacial advancement. Today, DO is the most powerful tool to simultaneously correct both exorbitism and the respiratory impairment of the faciocraniosynostosis, but practices vary greatly between teams. METHODS Current practices, controversies, and near-term future applications will be outlined and discussed. RESULTS Our current treatment strategy for faciocraniosynostosis is based on early intervention (<18 months of age) to prevent irreversible brain damage. In the first 6 months of life, infants with faciocraniosynostosis receive posterior vault decompression. We currently use posterior vault distraction, using 2 internal distractors. Around 18 months of age, a frontofacial monobloc advancement with DO is performed. It further decompresses the brain, improves respiratory function, and corrects exorbitism. Because we operate at such an early age, we favor internal over external distractors. In severe faciocraniosynostosis, when midface hypoplasia causes major exorbitism endangering the eye or causes respiratory distress requiring a tracheotomy, we do not hesitate to perform a frontofacial monobloc advancement with DO before the age of 18 months, reinforcing the frontozygomatic junction with a plate and placing a transzygomatic pin. The pin is then connected to a traction rope. We frequently use the external distractors, which allow precise control over the rotation of the maxilla and are well tolerated after 5 years of age. When midface hypoplasia is very severe, we combine external and internal distractors. CONCLUSIONS The ongoing debate between proponents of internal versus external distractors or 1-stage versus 2-stage approach is based mostly on anecdotal data. Multicenter prospective studies are necessary to bring objective data to answer these questions.

Complex wound-healing problems in neurosurgical patients: risk factors, grading and treatment strategy. Acta Neurochir (Wien) 2012; 154:541-54.

Abstract
BACKGROUND Wound-healing problems in the neurosurgical patient can be particularly bothersome, owing to various specific risk factors involved. These may vary from simple wound dehiscence to complex multi-layer defects with cerebrospinal fluid (CSF) leakage and contamination. The latter is quite rare in practice and requires an individually titrated reconstruction strategy. The objective is to retrospectively analyze neurosurgical patients with complex, recalcitrant wound-healing problems we had treated in our department, attempt to develop a grading system based on the risk factors specific to our specialty and adapt a surgical reconstruction algorithm. METHODS During an 11-year period, 49 patients were identified to have had complex, recalcitrant wound-healing problems involving the cranial vault (n = 43) and the skull base (n = 6) that required an adapted surgical wound-management strategy. The etiologies of wound healing problems were aftermaths of surgical treatment of: (1) brain tumors (nine cases), (2) aneurysm clipping (ten cases), (3) trauma (27 patients), and (4) congenital malformations (three patients). Local rotational advancement flaps were performed in 18 patients and free microvascular tissue transfer was performed in 37 cases. RESULTS Major risk factors leading to recalcitrant wound healing problems in the presented group were: prolonged angiographic interventions (20%), ongoing chemotherapy or radiotherapy (47%), prolonged cortisone application (51%), CSF leak (76%) and, above all, multiple failed attempts at wound closure (94%). Stable long-term wound healing was achieved in all patients using vascularized tissue coverage. A ternary grading system was developed based on various risk factors in the presented cohort. Accordingly, the algorithm for reconstruction in neurosurgical patients was adapted. CONCLUSIONS Primary disease, treatment history, and distorted anatomical structures are major concerns in the management of complex wound-healing problems in neurosurgical patients. The higher the risk factors involved, the more complex is the surgical strategy. Free microvascular tissue transfer offers stable long-term results in recalcitrant cases. However, this may be indicated only in patients with a good prognosis of the underlying disease.

Abstract
Osteomyelitis of the craniofacial skeleton closely resembles osteomyelitis elsewhere in the body in its pathophysiology and medical management; subsequent reconstruction after debridement remains distinctly challenging. The goals of reconstruction must include the restoration of the complex and readily visible morphology of the cranium and face, as well as the adequate return of vital sensory, expressive, and digestive functions. In this article, the various reconstructive modalities will be discussed including pedicled and nonpedicled flaps with or without an osseous component, nonvascularized bone grafts, alloplastic implants, and bone regeneration using protein therapy. Although reconstruction of craniofacial defects after osteomyelitis commonly proves formidable, the satisfactory return of form and function remains a plausible reconstructive goal.

Abstract
BACKGROUND Cranial bone defects secondary to decompression craniectomy associated with the Global War on Terror pose a unique reconstructive challenge. The objective of this study was to evaluate the outcome of alloplastic reconstruction using custom-designed implants for large craniectomy defects from warfare-related cranial trauma. METHODS A review of injured personnel who underwent decompression craniectomy reconstruction and subsequent alloplastic cranial reconstruction in the National Capital Region was performed from 2003 to 2008 (n = 99). Collected data included mechanism of injury, evacuation time, Glasgow Coma Scale score, decompression craniectomy type, and implant type. Outcomes included complications and retention of implants. RESULTS Average patient age was 25 years (range, 18 to 53 years). All patients were men. Follow-up was 2.4 years. Improvised explosive device blasts were responsible for 46 percent of injuries. The initial Glasgow Coma Scale score was 7. On arrival to the continental United States, it was 9. Time for evacuation to the continental United States was 6 days. Eighty-eight percent had hemicraniectomies and 12 percent had bifrontal craniectomies. Successful reconstruction with retention of the implant occurred in 95 percent. Five (three hemicraniectomy and two bifrontal) patients underwent implant removal because of infection. Seventy-three patients were complication-free. The reoperation rate with recontouring, drainage, or removal was 18 percent. After reconstruction, seven patients developed hematomas/hygromas, three patients developed seizures, and 10 percent had contour abnormalities (temporal hollowing) requiring revisions. CONCLUSIONS Despite war wound contamination, massive cranial defects can be successfully reconstructed using custom alloplastic implants. However, reconstruction of frontal cranial defects in proximity to the airways and orbits was associated with infection and implant removal.

Abstract
The prevalence of penicillin-resistant Streptococcus pneumoniae (PRSP) meningitis has increased worldwide, particularly in East Asia and the United States. We recently experienced a case of PRSP meningitis that developed during frontofacial distraction. The patient was a 7-year-old girl with Crouzon disease who was treated by frontofacial monobloc/Le Fort IV minus glabellar osteotomy with quadruple internal distraction devices. Penicillin-resistant Streptococcus pneumoniae meningitis was diagnosed after surgery and treated successfully with meropenem (a carbapenem) at 120 mg kg d every 8 hours, ceftriaxone (a third-generation cephalosporin) at 100 mg kg d every 12 hours, and vancomycin (a glycopeptide) at 45 mg kg d every 6 hours. This case indicates that severe and fatal bacterial meningitis may occur as a postoperative complication due to multidrug-resistant bacteria indigenous to the nasal cavity after simultaneous osteotomy of the cranium and facial bone in intracraniofacial surgery, such as that for syndromic craniosynostosis and hypertelorbitism. In such cases, preventive strategies should include preoperative administration of pneumococcal vaccine, preoperative screening of nasal bacterial flora by nasal culture test, and prior administration of a carbapenem with good cerebrospinal fluid transfer or a third- or fourth-generation cephem covering PRSP. Postoperatively, suspected meningitis may be treated with a combination of the 3 drugs used in our case, in parallel with emergency cephalic contrast computed tomography and culture tests of blood and cerebrospinal fluid. Our experience suggests that these measures will facilitate a successful outcome in frontofacial distraction osteogenesis.

Abstract
BACKGROUND Previously, we have reported the pattern of temperature increase after transcranial surgery for nonsyndromic craniosynostosis. It was found that pyrexia had a bimodal distribution during the first 48 hours after surgery. AIM The aims of this study were to evaluate pyrexia after transcranial surgery for syndromic craniosynostosis (Pfeiffer syndrome), to investigate whether the same pattern occurred, and to evaluate the correlation between pyrexia and possible factors, that is, sex, age, procedure, length of surgery, and incidence of postoperative cerebrospinal fluid (CSF) leakage. METHOD Twenty-one sequential case notes of Pfeiffer syndrome were retrospectively reviewed to collect 38 postoperative temperature courses. The mean change of temperature was plotted on a graph with a trend line to find the feature of the course. RESULTS Pyrexia after transcranial surgery for Pfeiffer syndrome had a bimodal distribution during the first 48 hours, similar to the pyrexia after transcranial surgery for nonsyndromic craniosynostosis. This pyrexia was higher and more prolonged in those undergoing a longer surgical procedure and frontofacial advancement and procedures accompanied with postoperative CSF leakage. Moreover, the temperature course was more complex in procedures accompanied with postoperative CSF leakage. CONCLUSIONS It was concluded that in Pfeiffer syndrome, which has more complicated pathologic status than nonsyndromic craniosynostosis, also had bimodal postoperative temperature course. Although the etiology of the bimodal pyrexia remains unclear, it seems that it is part of the normal postoperative course in these cases. However, prolonged raised temperature within the first 48 postoperative hours may suggest a complication.

Abstract
LEARNING OBJECTIVES After studying this article, the participant should: 1. Be able to define indications and timing for secondary cranioplasty. 2. Understand the surgical options for reconstructing the cranium and overlying soft-tissue defect including their advantages and disadvantages. 3. Be able to apply this knowledge to the clinical setting of an infectious bone flap loss. BACKGROUND Infection after craniotomy occurs in approximately 1.1 to 8.1 percent of cases and often necessitates bone flap removal. For a secondary cranioplasty, there is an increased risk of recurrent infection, which influences the reconstructive plan. The soft tissue/scalp is frequently compromised by infection, sequelae of prior surgery, and/or adjuvant radiation therapy. METHODS A literature review was conducted to compile and summarize the indications for secondary cranioplasty after infectious bone flap loss, the timing of the procedure, and the surgical options for bone and soft-tissue reconstruction. In coordination with soft-tissue coverage, cranioplasty options include alloplastic reconstruction, allogeneic or autogenous bone grafts, and free tissue transfer. RESULTS The literature review identified the following factors that must be considered in the treatment plan for secondary cranioplasty after postneurosurgical bone flap loss: indications, timing of reconstruction, soft-tissue status and the need for soft-tissue reconstruction, and method of cranioplasty. CONCLUSIONS Treatment recommendations for cranioplasty in the clinical setting of infectious postneurosurgical bone flap loss are presented. These guidelines consider the risk factors for a recurrent infection, the condition of the soft-tissue coverage, and the concavity of the preoperative cranial deformity.

Abstract
OBJECTIVE To review the complications in the surgical treatment of craniosynostosis in 306 consecutive transcranial procedures between June 1999 and June 2007. PATIENTS AND METHODS Surgical series consist of 306 procedures done in 268 patients: 155 scaphocephalies, 50 trigonocephalies, 28 anterior plagiocephalies, one occipital plagiocephaly, 20 non-syndromic multisutural synostosis and 32 craniofacial syndromes (11 Crouzon, 12 Apert, seven Pfeiffer and two Saethre-Chotzen) Complications and time of hospitalisation were reckoned. Surgical procedures were classified in 12 different types according to the technique: Type I: frontal-orbital distraction (26 cases); Type II: endoscopic assisted osteotomies in sagittal synostosis (39 cases); Type III: sagittal suturectomy and expansive osteotomies (44 cases); Type IV: same as type III, but including frontal dismantling or frontal osteotomies in scaphocephalies (59 cases); Type V: complete cranial vault remodelling (holocranial dismantling) in scaphocephalies (13 cases); Type VI: frontal-orbital remodelling without frontal-orbital bandeau in trigonocephaly (50 cases); Type VII: frontal-orbital remodelling without frontal-orbital bandeau in plagiocephaly (14 cases); Type VIII: frontal-orbital remodelling with frontal-orbital bandeau in plagiocephaly (14 cases); Type IX: Occipital advancement in posterior plagiocephaly (one case); Type X: Standard bilateral front-orbital advancement with expansive osteotomies (28 cases); Type XI: holocranial dismantling (complete cranial vault remodelling) in multisutural craniosynostosis (12 cases); Type XII: occipital and suboccipital craniectomies in multiple suture craniosynostosis (six cases). RESULTS There was no mortality and all complications resolved without permanent deficit. Mean age at surgery was 6.75 months. Most frequent complication was non-filiated postoperative hyperthermia (13.17% of the cases) followed by infection (8.10%), subcutaneous haematoma (6.08%), dural tears (5.06%) and cerebrospinal fluid (CSF) leakage (2.7%). Number and type of complications was higher among the group of reoperated patients (12.8% of all): 62.5% of all the series infections, 93% of all dural tears and 75% of all CSF leaks. In relation to surgical procedures, endoscopic assisted osteotomies reported the lowest rate of complications, followed by standard frontal-orbital advancement in multiple synostosis, trigonocephalies and plagiocephalies. Highest number of complications was related to complete cranial vault remodelling (holocranial dismantling) in scaphocephalies and multiple synostoses and after the use of internal osteogenic distractors. Special consideration deserves two cases of iatrogenic basal encephaloceles after combined frontal-facial distraction. Finally, we establish considerations based on the complications related to every specific technique. CONCLUSIONS Percentage and severity of complications relates to the surgical procedure and is higher among patients going for re-operation. Mean time of hospitalization is also modified by these issues.

Abstract
BACKGROUND Surgical treatment of faciocraniosynostosis is a complex problem that includes both function and aesthetics. Treatment goals are to prevent further neurologic disorders and to correct the morphologic impairment. METHODS Thirty-six patients with faciocraniosynostosis (mean age, 5.2 years) were evaluated prospectively after frontofacial monobloc advancement and quadruple internal distraction. Four distractors were used in combination with a frontofacial monobloc advancement osteotomy. Complications and advancement were evaluated clinically and radiographically. Respiratory status was evaluated by polysomnography. Relapse was evaluated by comparing results at the time of distractor removal to 6-month values. The mean follow-up was 30 months. RESULTS Distraction was completed in 35 patients. Twenty-eight patients (80 percent) completed their distraction uneventfully in the initial period. In seven patients, a problem related to the distraction devices required revision surgery, and subsequently six of them completed the distraction. One patient died the day after surgery from acute brain tonsillar herniation before distraction was begun. The exorbitism was corrected clinically in all patients in whom distraction was completed (n = 34). A class I occlusal relationship was obtained in 28 of 35 patients (80 percent). When respiratory impairment was present, it was corrected in all but two cases (14 of 16). A septic frontal osteonecrosis occurred in one patient 2 months after distraction was completed (frontal bone loss in one of 35 patients). Reossification at time of distractor removal was limited. Relapse has been observed predominantly at the occlusal level (six of 35) and more frequently in Pfeiffer syndrome. CONCLUSIONS Internal distraction allows for early correction of respiratory impairment and exorbitism of faciocraniosynostosis, and limits the major risks of frontofacial monobloc advancement. Previous operations performed before the frontofacial monobloc advancement increased its morbidity.

Abstract
While calcified cephalohematoma is eminently correctable, a clear description of indications for surgery and surgical techniques are currently lacking in the literature. In this paper we propose a simple classification and an algorithm for the management of cephalohematomas. Three patients were treated for large calcified parietal cephalohematomas. Craniectomy and cranioplasty were performed with excellent outcome. Cranioplasty was performed with the cap radial craniectomy technique in two patients and the flip-over bull's-eye technique in one patient. The literature was reviewed on this entity and an algorithm based on the timing of presentation, extent of calcification and type of calcified cephalohematoma is proposed. Aspiration and compressive dressings can be used for early, incompletely calcified cephalohematomas. Calcified cephalohematoma causing significant distortion of the calvarium requires surgical correction and is classified as Types 1 or 2 depending on the contour of the inner lamella. Type 1, with a normal contoured inner lamella, can be corrected by ostectomy of the outer lamella. Type 2 calcified cephalohematoma has a depressed inner lamella. Elevation of the inner lamella is necessary and the cap radial craniectomy technique can be used. We describe a novel technique, the flip-over bull's-eye techniques as an alternative technique for Type 2 lesions in selected patients. In conclusion, calcified cephalohematomas can safely be treated surgically with excellent outcome. It is hoped that this algorithm will serve as a useful and logical guide in decision making for the management of this condition.

Abstract
Eleven patients with syndromic craniosynostosis were treated with gradual distraction fronto-orbital advancement using "floating forehead." The frontal and supraorbital area was cut and remolded. Bony orbits were widened in three patients. Frontal bone was let floating on the dura and fixed loosely with absorbable threads to remolded supraorbital bone. A pair of distracters with hinge plates (A.V.D. system, Bear Medic Corp, Tokyo, Japan) was fixed between the temporal area and supraorbital bone. Distraction was begun 5 to 7 days after the surgery, and 1.8 to 3.2 cm advancement was obtained. Distracters were taken off after 3 to 7 weeks of consolidation periods. Although no major complication was encountered, some minor complications related to the devices were experienced.

Abstract
BACKGROUND Traditional Le Fort III osteotomies have been described by several authors; however, few have reported the distances advanced and stability over time. METHODS The authors assessed their last 30 Le Fort III osteotomies with respect to the immediate incisor advancement achieved at surgery and long-term advancement as measured at the A-point from preoperative and postoperative cephalometric tracings. The authors then compared their results with those in the literature for Le Fort III distraction techniques. Comparisons were made with respect to distraction distance maintained, the need for bone grafting, airway results, morbidity, and cost. RESULTS The mean incisor advancement at the time of surgery as recorded in 14 patients was 21.6 mm (range, 12 to 28 mm). The long-term cephalometric A-point measurements in 14 patients demonstrated a mean of 14.14 mm (range, 8 to 25 mm). CONCLUSION The authors conclude that, at the present time, no significant improvement in the results using Le Fort III distraction osteogenesis when compared with traditional methods has been shown.

Abstract
BACKGROUND Craniofacial surgery for facial advancement or correction of severe craniofacial malformations such as orbital hypertelorism, Crouzon's disease, and Apert's syndrome may carry great risk. Postoperative infection after craniofacial surgery is a life-threatening complication. Ascending infection via nasofrontal communication in frontofacial monobloc advancement, intracranial Le Fort III osteotomy, correction of hypertelorism (intracranial approach), and acute trauma of cribriform plate can lead to life-threatening meningitis and meningoencephalitis. METHODS A four-layer sealing technique for the closure of nasofrontal communication using Gelfoam, galeopericranial flap, rib bone graft, and Tissel is a very effective method. Until the rib bone graft is taken up, Gelfoam is used to temporarily block bony defects and prevents displacement of the rib bone graft. The authors used galeoperiosteal flap for the sufficient blood supply to the rib bone graft. Tissel is used as a biologic adhesive and for blockage of the surrounding gaps. RESULTS There were no cases of cerebrospinal fluid rhinorrhea, epidural abscesses due to nasofrontal ascending infection, or meningitis, and no cases underwent débridement due to necrosis of the frontal bone flap. This indicated that the blockage of nasofrontal communication was successful in this series. Moreover, postoperative cosmetic outcomes were satisfactory. CONCLUSION This study indicated that the blockage using the Gelfoam, galeopericranial flap, rib bone graft, and Tissel application was effective for the thorough management of nasofrontal fistula and the prevention of recurrent episodes.

Abstract
Pyrexia after transcranial surgery has been observed regularly in clinical practice but does not usually herald any subsequent pathologic process. However, the significance and incidence of this phenomenon remain uncertain. The aim of this study was to evaluate the incidence and timing of any pyrexia after transcranial surgery for craniosynostosis correction and correlate this with the clinical outcome to assess its significance. Retrospective review of sequential case notes collected over a 10 year period identified 136 transcranial operations undertaken for 122 cases of nonsyndromic craniosynostosis. The incidence of postoperative pyrexia of 38 degrees or more in the first 5 days was 76%, whereas that greater than 39 degrees was 11%. Pyrexia was noticed during the first 48 hours and had a bimodal distribution. Only a single case in this series subsequently developed a clinically significant complication, that is, a minor wound infection of the skin, which was treated by antibiotics and dressings. The occurrence of pyrexia did not appear to be related either to sex or to any affected suture but occurred less frequently in those who were under 6 months old. We conclude that this pyrexia should be considered to be a part of the normal physiological response to craniofacial surgery.

Abstract
In the conventional fronto-orbital advancement method, there is a limit to advancement because of scalp skin tension and an absence of a supraorbital bar fixating point. In a case of insufficient advancement after the primary operation, a secondary re-advancement must be performed. In such a condition, additional fronto-orbital advancement by distraction osteogenesis has proved to be very useful. The authors used additional distraction osteogenesis in three infant cases: two of nonsyndromic craniosynostosis and one of Apert's syndrome. They were able to perform these operations safely using their original internal devices. Distraction was started 3 days after the operation. The rate of advancement was 0.5 to 1.0 mm per day. The distraction distances ranged from 16 to 22 mm. They were able to gain enough advancement in all three cases. A reoperation of a fronto-orbital advancement is more difficult than the primary operation because of possible infection, much loss of blood, low blood supply to advanced bones, a tendency of advanced bones to relapse, increased scalp skin tension, and the existence of bone defects. In these poor conditions, distraction osteogenesis has many advantages: good vascularization, no relapsing, a low infection rate, and no need for bony fixating points in the bone defects. Although it is necessary to have a secondary operation to remove the devices and prolonged hospitalization is required, the disadvantages are far outweighed by the many advantages when performing additional fronto-orbital advancement.

Abstract
Abstract
OBJECTIVE:
Surgical site infections (SSIs) after pediatric intracranial surgery for craniofacial malformations are relatively common and potentially serious nosocomial infections. Despite this, few studies have been published on this topic. We performed a retrospective study to determine the incidence of and factors associated with SSIs after intracranial surgery for craniofacial malformations at a single multidisciplinary craniofacial center during a 6-year period.
METHODS:
Retrospective chart review was performed on 254 patients who underwent 281 intracranial procedures during a 6-year period. Patients with SSIs (cases) were compared with those without SSIs (controls). National Nosocomial Infection Surveillance System criteria were used to identify cases of SSI.
RESULTS:
SSIs occurred in 9 (3.2%) of 281 intracranial procedures that took place during the study period. Factors associated with an SSI included a complicated diagnosis comprising a diagnosis of syndromic craniosynostosis, frontonasal dysplasia, or oblique facial cleft (odds ratio [OR], 13.0; 95% confidence interval [CI], 2.6–64.4); duration of surgery longer than 426 minutes (OR, 12.1; 95% CI, 2.4–59.9); closure of skin under tension (OR, 12.5; 95% CI, 3.0–52.6); use of bovine pericardium (OR and 95% CI undefined); more than four surgeons present during surgery (OR, 6.3; 95% CI, 1.2–32); pediatric intensive care unit stay longer than 2 days (OR, 10.8; 95% CI, 2.2–53.3); and use of a ventilator after surgery (OR, 4.8; 95% CI, 1.2–18.6).
CONCLUSION:
In this study, the presence of a complicated diagnosis and a number of other factors were associated with an SSI after pediatric intracranial surgery for craniofacial malformations. We speculate that a complicated diagnosis may be a marker for other factors that contribute to the risk of an SSI. Future studies investigating SSIs after intracranial surgery should consider these factors.

Abstract
The management of the hypoplastic midface in syndromic craniosynostosis remains a great challenge. Frequently, patients have to be operated on numerous times to achieve a satisfactory end result, partially because of the limited skeletal advancement possible when using traditional surgical techniques. During the last decade, however, methods for gradual midfacial distraction have been presented, whereby greater advancements can be obtained. We present four children aged 17 months to 15 years with severe syndromal craniosynostosis in need of midface advancements because of severe respiratory obstruction or severe exophthalmos. These patients were complex cases with several previous craniofacial surgeries (mean of three times, range of two to six times) that yielded insufficient skeletal advancements. They were operated on with gradual monobloc advancements using the Modular Internal Distraction System. The mean length of operations was 370 minutes (range: 240-455 minutes), and the mean amount of perioperative blood transfusion needed was 1,300 ml (range: 280-2,700 ml) or 66.9 ml/kg (range: 31.1-94.9 ml/kg). The patient with the greatest number of previous operations also had the longest operation time as well as the most blood loss. The average midface advancement obtained was 25 mm (range: 20-30 mm), resulting in cessation or a significant decrease of preoperative respiratory problems, reduced exophthalmos, and improved facial profile. Apart from a local infection in one patient with a connective tissue disorder and several previous wound infections, no major postoperative complications were recorded. Distraction osteogenesis has become a versatile and safe technique that allows for large advancements of the midface.

Abstract
Craniofacial surgery almost always requires the use of bone grafting. Although autografts are the standard procedure for bone grafting, it is sometimes not possible to harvest bone, and autografts have particular risks. The use of allograft bone provides a reasonable alternative to meet the need for graft material. Solvent dehydration is a multistage procedure in which human cadaveric bone is processed by osmotic exchange baths and gamma sterilization. This processing avoids the risk of infection transmission, decreases antigenicity, and does not weaken the mechanical properties of the bone. Solvent-dehydrated, gamma-irradiated human calvarial bone allografts were used for reconstruction of craniofacial deformities in 24 patients between 1988 and 2002. Resorption of the allografts and results of the surgical intervention were evaluated with plain radiographs and three-dimensional computed tomography 12 months after surgery, in 21 patients. Serologic tests for human immunodeficiency virus-1 antibody, hepatitis B surface antigen, and hepatitis C antigen were also performed. Biopsy specimens were taken from the allografts. Average follow-up in this group was 30 months (range, 8 to 60 months), and results of serologic tests were negative in all patients. Seventy-one percent of the patients (15 of 21) showed no resorption, with partial and complete allograft fusion. One patient had nearly total graft loss and the remaining five patients had 10 to 25 percent graft resorption. Rigid fixation of the allograft, contact with the dura and periosteum, and prevention of dead spaces around the allograft are the most important factors in achieving a satisfactory result. In solvent-dehydrated bone allografts, sterilization and antigenic tissue cleaning are achieved after several steps with a minimal dose of radiation. The result is a nonantigenic, sterile mechanical scaffold that can tolerate external forces. Although autografts are the standard in craniofacial surgery, solvent-dehydrated calvarial bone allografts produced successful results in selected cases.

Abstract
From January 2000 to December 2001, six patients with craniosynostosis were treated. Involved sutures were coronal sutures in three patients, coronal and metopic sutures in one patient, multiple sutures (brachycephaly and oxycephaly) in one patient, and multiple sutures with a cloverleaf skull deformity in one patient. The age distribution of the patients was 4 months to 3 years. Four were male, and two were female. A frontal craniotomy was performed in four patients with brachycephaly. In one patient with brachycephaly, the osteotomies were made across the nasofrontal junction, across the roof of the orbit, and along the lateral orbital wall. In one patient with a cloverleaf skull deformity, a frontal bone osteotomy was first performed 1 cm above the roof of the orbit. A supraorbital frontal bar was then made across the nasofrontal junction, across the roof of the orbit, and down to the lateral orbital wall. The frontal bone flap was repositioned to the supraorbital bar using absorbable miniplates and screws. Distraction was started 3 to 7 days after the operation at a distraction rate of 1 mm/d. The real duration of the first operation was 90 to 120 minutes, and the second operation to remove the device took 40 to 50 minutes to perform. The distracted length was 15 to 25 mm. The consolidation period was 3 to 5 weeks. The follow-up period was 6 months to 1 year. Postoperative three-dimensional computed tomography demonstrated reossification at the bone flap and advancement of the fronto-orbital area. After surgery, the cranial volume increased 22.7% on average compared with before surgery. The mean ratio of the anteroposterior length to the transverse length of the cranial vault was changed from 0.96 before surgery to 1.04 after surgery. In conclusion, the advantages of distraction osteogenesis of the cranial vault are that it offers a less invasive technique, a shorter operation time, easy care, and postoperative safety as a result of minimal dissection of the dura. Disadvantages are the limited possibility of initial reshaping and the necessity of one more operation for device removal.

Abstract
LEARNING OBJECTIVES After studying this article, the participant should be able to: 1. Review the etiopathogenesis of craniosynostosis and craniofacial anomalies. 2. Develop a basic understanding of the clinical manifestations and diagnosis of craniofacial anomalies. 3. Describe the surgical principles of managing craniosynostosis and craniofacial anomalies.Craniosynostosis, or the premature closure of calvarial sutures, results in deformed calvaria at birth. Although the etiology of craniosynostosis is currently unknown, animal experiments and a recent interest in molecular biology point toward interplay between the dura and the underlying brain. This interaction occurs by means of a local alteration in the expression of transforming growth factor, MSX2, fibroblast growth factor receptor, and TWIST. The fused suture restricts growth of the calvaria, thus leading to a characteristic deformation, each associated with a different type of craniosynostosis. Uncorrected craniosynostosis leads to a continuing progression of the deformity, and in some cases, an elevation of intracranial pressure. Clinical examination should include not only an examination of the skull but also a general examination to rule out the craniofacial syndromes that accompany craniosynostosis. Because deformational plagiocephaly, or plagiocephaly without synostosis, occurs secondary to sleeping in the supine position during the early perinatal period, the physician should be aware of this abnormality. Treatment for deformational plagiocephaly is conservative when compared with treatment for craniosynostosis, which requires surgery. Appropriate investigations should include genetic screening, radiologic examination with a computerized tomographic scan, and neurodevelopmental analysis. Surgical intervention should be performed during infancy, preferably in the first 6 months of postnatal life, to prevent the further progression of the deformity and possible complications associated with increased intracranial pressure. The principles of surgical intervention are not only to excise the fused suture but also to attempt to normalize the calvarial shape. Long-term follow-up is critical to determine the effect of the surgical outcome.

Abstract
Craniofacial units have a responsibility to collect data, to promote research and training and to carry out audit. We present a review of 114 consecutive transcranial procedures performed in 110 children in our unit over an 8 year period, with particular reference to complications. There were no deaths in this series. Complications included two cases of excessive intraoperative blood loss necessitating a delay in the procedure, and two postoperative infections that required aggressive antibiotic management. Minor complications, delaying hospital discharge, occurred in 13 patients. Within the range of paediatric transcranial procedures performed, the potential for complications is greater for complex osteotomies in syndromic conditions than for single sutural synostosis correction. The transcranial case mix included a relatively small number of craniofacial dysostoses, which contributes to the very low complication rate reported. This report demonstrates that multidisciplinary assessment and planning, adherence to craniofacial surgical principles, shorter operating times and avoidance of high-risk procedures contribute to a low complication rate, and confirms that paediatric transcranial procedures can be safely performed in dedicated centres where there is a multidisciplinary team with appropriate commitment and experience.

Abstract
Application of gradual external forces to correct craniofacial deformities challenges many procedures in conventional craniomaxillofacial surgery. Distraction osteogenesis is replacing traditional osteotomies for correction of patients with craniomaxillofacial deficiencies. However, the reverse concept, contraction osteogenesis, has yet to be established for patients with craniomaxillofacial excesses. The purpose of this investigation is to demonstrate the contraction osteogenesis phenomenon applied in a controlled animal model during the craniofacial growth period. Twenty-six 26-day-old rabbits were assigned to one of four groups: 0, control; 1, pin control (pin insertion); 2, no contraction (pins and contraction device application, without active contraction); and 3, contraction (pin insertion, contraction device application, and active contraction). An external fixator was placed across the incisive-maxillary suture, and the effects after 4.5 weeks of contraction at a rate of 0.5 mm twice a week were compared with control groups. The results were assessed by craniometric and cephalometric measurements and by histologic examination. Gross alterations were evident in the contraction group, characterized by midface anteroposterior shortening, maxillary regression, snout deviation, and anterior crossbite. Histologic examination of the contraction group demonstrated a significant increase in osteoblastic activity. Contraction osteogenesis is a new treatment concept in craniofacial development and may offer therapeutic opportunities for shortening skeletal structures without the need of osteotomies, thus taking advantage of the potential of craniofacial growth and remodeling.

Abstract
Tumors of the clival and parapharyngeal areas are a challenge because of their location. They used to be considered inaccessible because the aggressive approaches employed caused elevated levels of morbidity. This fact led to more conservative approaches that attempted to preserve the exposure of the lesion. These approaches were a combination of cranial and facial procedures, thus utilizing a combined effort between neurosurgeons and maxillofacial surgeons. We described our experience with a partial segmented Le Fort I osteotomy added to a transmandibular approach to expose a chordoma of the clivus and left parapharyngeal space. A three-dimensional imaging was used as a diagnostic tool and to plan the optimal surgical approach. The operative technique was described in this case study. Some important technical details of the approach are described. The global outcome was favorable.

Abstract
Severe basilar impression leads to an upward translocation of the upper cervical spine and clivus into the foramen magnum and is a diagnosis best made with computed tomography or magnetic resonance imaging scans. Basilar impression may be a primary condition or secondary to bone softening disorders. Symptoms relating to direct neuraxial compression, obstruction to cerebral spinal fluid outflow, and vascular compromise all have been described. Management depends on the exact nature of the abnormality seen, but it is now firmly accepted that those with anterior neuraxial compression should have an anterior decompression. The severe basilar impression and craniofacial abnormalities seen in osteogenesis imperfecta together with the progressive nature of the condition have led to the development of a specific surgical response, the open door maxillotomy combined with a contoured loop fixation of the cervical spine. Little is known of the long term outcome of severe basilar impression, and long term studies undertaken by centers familiar with the condition and its management are required if definitive care is to be delivered to these patients.

Abstract
Fourteen patients underwent Le Fort III midface advancement using distraction techniques. Six have cephalometric documentation extending beyond 1 year postoperatively, and the positions of cephalometric points A and orbitale over time are reported here. Excellent stability of advancement at the occlusal level and some relapse at the level of orbitale are documented. Elimination or diminution of obstructive sleep apnea occurred in all patients so affected, and one of two patients with tracheostomy has been decannulated. Speech effects have been mild or transient. No untoward effects on extraocular muscle function have occurred.

Abstract
The Le Fort I, split-palate approach provides intraoral surgical access to a region of the midline skull base ranging from the upper clivus to the second cervical vertebra. Although this approach provides perhaps the largest exposure of all the intraoral techniques, there is little concerning it in the literature. Furthermore, there are no detailed descriptions of case histories, complications, and outcome. The purpose of this study was to evaluate this procedure's effectiveness and identify associated complications as well as outcome. Seven cases of patients who underwent eight skull base surgeries using the Le Fort I, split-palate approach were evaluated retrospectively. Particular attention was paid to postoperative occlusion, speech, mouth opening, infection, tumor recurrence, postoperative recovery period, and viability of maxillary bone and teeth. Follow-up ranged from 4 months to 7 years with a mean of 3.9 years. Pathologic diagnoses included three chordomas (two recurrent), one recurrent meningioma, one liposarcoma, one chondrosarcoma, and one inflammatory mass. One patient with chordoma underwent a second operation using the same approach. No deaths or major neurologic problems related to the procedure occurred. One patient who had known local metastases at the time of operation died several months after surgery. All other patients are still living. Duration of hospital stay ranged from 5 to 53 days with a mean of 25.4 days. Postoperative complications included one case of meningitis with an associated cerebrospinal fluid leak, three cases of malocclusion, one case of velopharyngeal insufficiency, and one extracranial soft-tissue infection. The case of meningitis was successfully treated by antibiotics. The malocclusions were corrected by conservative treatment. No problems with mouth opening or bone or tooth viability occurred. Tumor recurred in both cases in which malignancy was involved, whereas only one recurrence was noted among the benign cases. It is concluded that the Le Fort I-palatal split technique is a relatively safe and effective means for approaching midline skull base tumors. Several modifications to the surgical protocol and surgical technique are detailed herein.

Abstract
The most commonly used techniques for frontal sinus obliteration involve the implantation of an autogenous tissue graft: either fat, muscle or bone. Lyophilized allogenic cartilage due to its unique properties, such as the tendency to ossification and resistance to volume reduction, can be used as the material of choice for sinus obliteration. A clinical and radiological study of 66 patients operated on for frontal sinus fractures, between January 1 1988 through December 31 1995 was undertaken. Variables recorded included the aetiological factors, the clinical and radiological fracture features with the corresponding treatment modality, the association of frontal sinus fractures with intracranial involvement, the early and late postsurgical complications and the correlation between pre- and postoperative radiological findings. Obliteration of the frontal sinus with lyophilized cartilage chips was performed in 51 (77.3%) patients. The postsurgical evaluation showed no major complications. Revision of the frontal sinus was only required in one patient. The radiological findings verified the progressive calcification of the obliterated sinus. Allogenic lyophilized cartilage implantation offers distinct advantages in cases of severe frontal sinus trauma: 1. There is nearly unlimited availability of the material. 2. There is no need for a second operation field with the associated potential donor site morbidity. 3. The operation time is reduced due to the avoidance of a second operation on the donor site.

Abstract
A retrospective review was undertaken of 126 consecutive craniofacial procedures involving a transcranial component, performed at the Children's Medical Center at Dallas, between 1990 and 1994. Standard postoperative axillary temperature measurements were recorded until discharge. Age at surgery of less than 24 months correlated very strongly with a postoperative temperature of greater than 38 degrees C (r = -0.92). The incidence of postoperative fever was high in all age groups, yet there was still a significant difference between the group younger than 2 years and the group in which surgery was performed after the age of 2 years across all postoperative temperature ranges, from >38 degrees C to >39.5 degrees C (p < 0.001, chi-square test). The white blood cell count was elevated above the age-related normal in 67 percent of febrile patients. There was no correlation between type or duration of surgical procedure, length of intensive care or hospital stay, or the need for blood transfusion and the development of a significant postoperative fever. There were minor infectious complications in four patients (3 percent), only one of which was a wound problem related to the surgery. All infectious complications were easily identifiable clinically. There was no mortality or serious infections. The development of postoperative fever, and an elevated white blood cell count, is to be expected in pediatric patients undergoing craniofacial procedures. The routine laboratory investigation of postoperative fever in pediatric craniofacial patients under 2 years of age without procedures involving transgression of the paranasal sinuses is not warranted unless there are associated clinical indicators.

Abstract
Distraction osteogenesis is increasingly recognised as a potentially useful technique to achieve the co-ordinated augmentation of craniofacial skeletal and soft tissue. A case is presented where bilateral maxillary distraction was successfully used to advance the midface in the treatment of recurrent ocular dislocation, in a 10-month-old boy with Pfeiffer's syndrome.
