Kostares E, Kostares M, Kostare G, Tsakris A, Kantzanou M. Prevalence of free flap failure in mandibular osteoradionecrosis reconstruction: a systematic review and meta-analysis. Sci Rep 2024; 14:11087. [PMID: 38750124 PMCID: PMC11096303 DOI: 10.1038/s41598-024-61862-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Accepted: 05/10/2024] [Indexed: 05/18/2024] Open
Abstract
Our study aimed to estimate the prevalence of total free flap failure following free flap reconstruction for mandibular osteoradionecrosis (mORN) and assess the impact of potential moderators on this outcome. A comprehensive systematic literature search was independently conducted by two reviewers using the Medline, Scopus, Web of Science and Cochrane Library databases. Quality assessment of the selected studies was performed, and prevalence estimates with 95% confidence intervals (CI) were calculated. Outlier and influential analyses were conducted, and meta-regression analyses was employed to investigate the effects of continuous variables on the estimated prevalence. Ultimately, forty-six eligible studies (involving 1292 participants and 1344 free flaps) were included in our meta-analysis. The findings of our study revealed a prevalence of 3.1% (95% CI 1.3-5.4%) for total free flap failure after reconstruction for mORN. No study was identified as critically influential, and meta-regression analysis did not pinpoint any potential sources of heterogeneity. These findings provide valuable insights for researchers and serve as a foundation for future investigations into the management of mandibular osteoradionecrosis and the prevention of free flap failure in this context.

Abstract
BACKGROUND Osteoradionecrosis (ORN) of the skull base is a rare complication after head and neck radiation with a broad variety of subsequent complications. METHODS A 68-year-old woman with a complex oncological history (right-sided sphenoid meningioma; left-sided neck metastasis of a Cancer of Unknown Primary-CUP) was admitted with a right-sided epi-/ oropharyngeal mass and severe pain exacerbations for further evaluation. CT scan revealed an advanced ORN of the skull base with subsequent abruption of the ventral part of the clivus. This dislocated part of the clivus wedged in the oropharynx for 48 h and then moved towards the larynx, resulting in dyspnea and almost complete airway obstruction. RESULTS Due to the dangerous airway situation, an urgent exploration and removal of the dislocated clivus was necessary. After a potential cervical spine instability was ruled out, the patient's airway was initially secured with an awake tracheotomy and the clivus was removed transorally. The tracheostomy tube was removed during the ongoing inpatient stay, and the patient was discharged with significant pain relief. CONCLUSIONS The present case illustrates an orphan complication of skull base ORN resulting in a major airway emergency situation.

Abstract
BACKGROUND Medication related osteonecrosis of the jaw (MRONJ) requiring free flap (FF) reconstruction is uncommon with limited reported findings. METHODS Multicenter, retrospective case series of 49 consecutive adult patients presenting with advanced MRONJ requiring FF reconstruction from 2010 to 2022. Perioperative complications and outcomes were analyzed. RESULTS Eighty-two percent (n = 40) of cases were of the mandible and 18% (n = 9) were of the maxilla. The mean follow-up was 15 months (±19.6). The majority of FF survived (96%, n = 47). FF reconstructions of the maxilla were more likely to require postoperative debridement (56%, 95% CI [27, 81%] vs. 15%, 95% CI [7, 25%], p = 0.008) or develop intraoral bone exposure (56%, 95% CI [27, 81%] vs. 18%, 95% CI [9, 27%], p = 0.02). Most patients (71%, n = 35) received preoperative antibiotics which was associated with a higher rate of FF survival (100% vs. 86%, 95% CI [60, 96%], p = 0.02) and fewer complications. CONCLUSIONS Patients undergoing FF reconstruction for MRONJ do well with high rates of FF success. MRONJ of the maxilla have a higher rate of some complications. Preoperative antibiotics correlated with higher FF survival and fewer postoperative complications.

JAMA Otolaryngol Head Neck Surg 2023; 149:621-627. [PMID: 37261824 PMCID: PMC10236321 DOI: 10.1001/jamaoto.2023.1089] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2023] [Accepted: 04/06/2023] [Indexed: 06/02/2023]
Abstract
Importance Mandibular osteoradionecrosis (ORN) is a progressive disease that can be difficult to treat. Conservative measures often fail, while conventional definitive management requires a morbid segmental resection with osteocutaneous reconstruction. Evidence of the anterolateral thigh fascia lata (ALTFL) rescue flap technique's safety, effectiveness, and long-term outcomes is needed. Objective To determine the long-term outcomes of the ALTFL rescue flap procedure for treating patients with mandibular ORN. Design, Settings, and Participants This was a retrospective medical record review performed at a single tertiary-level academic health care institution with patients who were appropriate candidates for the ALTFL procedure to treat mandibular ORN from March 3, 2011, to December 31, 2022. Data analyses were performed from January 1 to March 26, 2023. Main Outcomes and Measures Patient characteristics, preoperative radiographic Notani staging, intraoperative defect size, length of stay, complication rates, and clinical and radiographic findings of progression-free intervals. Results The study population of 43 patients (mean [SD] age, 66.1 [47-80] years; 24 [55.8%] male individuals) included 52 cases of mandibular ORN. The preoperative Notani staging of the study population was known for 46 of the 52 total cases: 11 cases (23.9%) were stage I; 21 (45.7%), stage II; and 14 (30.4%), stage III. The mean defect area was 20.9 cm2. Successful arrest of ORN disease progression was noted in the clinical and radiographic findings of 50 of the 52 (96.2%) cases, with only 2 (3.8%) cases subsequently requiring fibular free flap reconstruction. The major complication rate was 1.9% (1 case). Clinical and radiographic progression-free intervals were assessed, and no statistically significant differences were noted between Notani staging groups (log-rank P = .43 and P = .43, respectively); ie, patients with stage III disease had no significant difference in risk of clinical (HR, 0.866; 95% CI, 0.054-13.853) or radiographic (HR, 0.959; 95% CI, 0.059-15.474) progression vs those with stage I disease. Weibull profiling revealed 96.9%, 94.6%, and 93.1% successful mandibular ORN arrest at 1, 3, and 5 years, respectively. The major complication rate was 1.9%. Mean (SD) length of stay was 2.7 (0.0-7.0) days. Mean (SD) radiographic follow-up was 29.3 (30.7) months. Conclusions and Relevance The findings of this large retrospective patient case series support the continued success of the ALTFL rescue flap technique, a safe and highly effective long-term treatment for mandibular ORN in carefully selected patients.

Plate-related complication and health-related quality of life after mandibular reconstruction by fibula flap with reconstruction plate or miniplate versus anterolateral thigh flap with reconstruction plate. Microsurgery 2023; 43:131-141. [PMID: 35553089 DOI: 10.1002/micr.30893] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2021] [Revised: 02/07/2022] [Accepted: 04/22/2022] [Indexed: 11/09/2022]
Abstract
BACKGROUND Plate-related complications are major long-term complications in mandible reconstruction. There are controversies regarding the use of a reconstruction plate versus miniplates and a bone flap versus a soft tissue flap with a bridging plate. Direct comparisons of a fibula flap and an anterolateral thigh flap, the applicability between a reconstruction plate and miniplate, and the correlation between plate-related complications and quality of life remain unclarified. Therefore, this study aimed to the explore complications of different flaps and plates and how they impact the patients' quality of life. METHODS We retrospectively reviewed the medical records of a total of 205 patients aged >18 years who underwent segmental mandibulectomy and reconstruction using fibula flap with reconstruction plate (FR; n = 86), fibula flap with miniplate (FM; n = 61), and anterolateral thigh flap with reconstruction plate (AR; n = 58) due to cancer ablation, osteoradionecrosis, or benign tumor excision between August 2010 and December 2019. Data on characteristics, complications, and health-related quality of life were collected and analyzed. RESULTS The plate-related complication rate was the highest in the AR group (37.9%), then in the FR group (25.6%), and was the lowest in the FM group (13.1%; p = 0.0079). The plate exposure rate was the highest in the AR group (24.1%), then in the FR group (15.7%), and was the lowest in the FM group (4.9%; p = 0.0128). The plate fracture and dislodge rates for the AR group were both higher than those for the FR and FM groups (24.1% versus 9.3% versus 9.8%, respectively; p = 0.023). The AR group had worse complication-free survival (hazard ratio [HR]: 3.61, 95% CI: 1.99-6.56, and p < 0.0001) than the FR and FM groups. Osteoradionecrosis (HR: 6.19, 95% CI: 2.11-18.21, and p = 0.0009) and postoperative radiotherapy (HR: 2.87, 95% CI: 1.34-6.12, and p = 0.0402) were both independent adverse factors for complication-free survival, whereas patient treated primarily (HR: 0.35, 95% CI: 0.17-0.73, and p = 0.0048) was an independent protective factor. Plate-related complication negatively impacted the quality of life based on pain scores (β: -0.56, SE: 0.26, and p = 0.034). CONCLUSIONS Using a fibular flap fixed with miniplates and avoiding the use of a reconstruction plate may yield a reduced plate exposure rate and better health-related quality of life, particularly for patients with osteoradionecrosis or those who need postoperative radiotherapy.

Reconstruction of mandibular defects in osteoradionecrosis and medication-related osteonecrosis of the jaw using fibula free flap and management of postoperative wound infections. Maxillofac Plast Reconstr Surg 2022; 44:37. [PMID: 36484930 PMCID: PMC9733773 DOI: 10.1186/s40902-022-00366-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Accepted: 11/30/2022] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Complications from osteoradionecrosis (ORN) and medication-related osteonecrosis of the jaw (MRONJ) include oro-cutaneous fistulas, necrotic bone exposure, soft-tissue defects, and pathologic fractures. The fibula free flap (FFF) is a common free flap method used to reconstruct the mandible in severe cases. Recently, we have used the FFF successfully for the reconstruction of ORN and MRONJ mandibular defects. We report this method as a recommended technique for the treatment of ORN and MRONJ and the management method of postoperative infections. METHODS Four patients who were diagnosed with ORN of the mandible and 3 patients who were diagnosed with MRONJ of the mandible were included in the study. Among the 7 patients, 3 patients also had pathologic fractures. Partial mandibulectomy and FFF reconstruction were performed at the Department of Oral and Maxillofacial Surgery, Samsung Medical Center from April 2019 to March 2021. RESULTS All 7 patients recovered following the reconstruction of the defect by FFF. Four patients experienced infections after surgery and pus cultures were performed. All were well healed without flap damage after changing the antibiotics by consultation with infectious medicine experts. CONCLUSION FFF is a widely used method and can provide an extensive flap to reconstruct the mandible, especially those affected by ORN or MRONJ. If an infection occurs after surgery, appropriate antibiotic changes should be made through cooperation with the infectious medicine department. Therefore, FFF is a well-established and recommended method even in cases of challenging reconstruction.

Abstract
OBJECTIVE Review QOL outcomes among patients undergoing segmental mandibulectomy and bony free flap reconstruction for ONJ. DATA SOURCES PubMed was searched for MeSH terms "Quality of life," "Osteonecrosis," "Osteoradionecrosis," "Bisphosphonate-associated osteonecrosis of the jaw," "Free tissue flaps," and "Mandibular reconstruction." REVIEW METHODS English language studies with QOL outcomes data for patients undergoing free flap reconstruction for advanced ONJ were included. 197 records were initially screened; 18 full texts assessed; 10 full texts included. PRISMA guidelines were followed. RESULTS Ten studies were included in this systematic review: six retrospective, three retrospective with comparison groups, and one prospective. In studies with comparison groups, ONJ patients have worse self-reported QOL than the general population as well as head and neck cancer patients without ONJ. Nearly all patients with QOL measurements (220/235 patients) had ONJ from prior radiation. Segmental mandibulectomy and bony free flap improved overall QOL in over half of patients, as well as pain associated with ONJ in 70-75 % of patients. Surgery did not improve long-term effects of radiation such as chewing, swallowing, and salivary production. Donor site morbidity rarely affects QOL. CONCLUSIONS Osteonecrosis of the jaw (ONJ) worsens quality-of-life, and advanced disease often requires segmental mandibulectomy and bony free flap reconstruction. Patients and surgeons may expect improvement in some, but not all, domains of patient-reported QOL by the use of segmental mandibulectomy and reconstruction for advanced ONJ.

Abstract
Osteoradionecrosis (ORN) of the jaw is one of the most dreaded complications of head and neck radiation therapy. Despite the evolution of radiation treatment modalities, ORN continues to remain a therapeutic challenge and its etiopathogenesis still remains unclear. It is clinically characterized by exposed necrotic bone within the head and neck radiation field. Over the past years, several studies have reported on the definition, staging, incidence, etiology, and management of this oral complication. In this review, we summarize the literature on ORN and discuss our institutional experience and management strategies that aim to predict and mitigate risk for ORN.

Abstract
A standard treatment for osteoradionecrosis (ORN) has not yet been established because of the diversity. Therefore, identifying the risk factors for a poor prognosis is essential. This study retrospectively investigated the factors associated with the prognosis of ORN in 68 patients. Relevant clinical data of all patients were obtained. Of the patients, 16 who underwent extensive surgery underwent histopathological analysis. The necrotic changes of the anterior and posterior margins in the cortical and cancellous bones were investigated. Multivariate analyses showed statistically significant associations between poor prognosis in patients with ORN and high radiation dose (hazard ratio [HR] 1.15), orocutaneous fistula (HR 2.93), and absence of sequestration (HR 2.49). Histopathological analysis showed a viable anterior margin of the middle portion of the cortical bone for all recovered cases; in contrast, most cases (75%) with a poor prognosis showed necrotic changes. The anterior margin of the cancellous bone was viable and resilient to high irradiation, regardless of the prognosis. These results suggest that patients with orocutaneous fistula should receive early surgical intervention, even if the affected area is limited or asymptomatic. In extensive surgery, a sufficient safety margin of necrotic bone, particularly in the anterior region, is required to improve the prognosis.

Abstract
As one of the most serious complications of radiotherapy, osteoradionecrosis (ORN) seriously affects the quality of life of patients and even leads to death. Vascular injury and immune disorders are the main causes of bone lesions. The traditional conservative treatment of ORN has a low cure rate and high recurrent. Exosomes are a type of extracellular bilayer lipid vesicles secreted by almost all cell types. It contains cytokines, proteins, mRNA, miRNA, and other bioactive cargos, which contribute to several distinct processes. The favorable biological functions of mesenchymal stem cells-derived exosomes (MSC exosomes) include angiogenesis, immunomodulation, bone regeneration, and ferroptosis regulation. Exploring the characteristic of ORN and MSC exosomes can promote bone regeneration therapies. In this review, we summarized the current knowledge of ORN and MSC exosomes and highlighted the potential application of MSC exosomes in ORN treatment.

Abstract
OBJECTIVE The objective of this study was to assess characteristics of patients with mandibular osteoradionecrosis (ORN) of severity necessitating segmental mandibulectomy and osteocutaneous free flap reconstruction. STUDY DESIGN This study is a retrospective review of patients who underwent free flap reconstruction of the mandible at the UCLA Medical Center between January 2016 and February 2020 secondary to ORN. RESULTS Twenty-nine charts with detailed dental and medical records were identified. Hypertension was reported in 14 of 29 patients, diabetes in 2 of 29, osteoporosis in 2 of 29, antiresorptive use in 3 of 29, tobacco use in 15 of 29, and alcohol use in 19 of 29. Twenty-three patients initially had stage III-IV cancer. The median radiation dose was 68 Gy and median time to ORN was 5.2 years. Chemotherapy was given in 21 patients and 4 had previous mandibular surgery. Twelve of 29 patients had surgical procedures identified as the causative factor and 17 of 29 occurred spontaneously. Median decayed, missing, and filled teeth score was 17 and 17 of 29 patients had grade II-IV periodontitis. Periodontitis was present in 8 of 17 of spontaneous and 1 of 12 of surgery cases. Twenty-five of 29 cases occurred in the same oral sextant as the tumor. CONCLUSION Severe ORN occurred at doses >60 Gy in most cases. Location of the primary tumor was predictive of site of ORN and only molars were involved when precipitated by tooth extraction. Risk of ORN persists indefinitely.

Abstract
BACKGROUND Skull base osteoradionecrosis (ORN) is a challenging treatment-related complication sometimes seen in patients with cancer. Although ORN management strategies for other anatomic sites have been reported, there is a paucity of data guiding the management of skull base ORN. OBJECTIVE To report a single-center tertiary care series of skull base ORN and to better understand the factors affecting ORN recurrence after surgical management. METHODS We conducted a retrospective cohort study of patients with skull base ORN treated at our center between 2003 and 2017. Univariate and multivariate binary logistic regressions were performed to identify predictors of recurrence. RESULTS A total of 31 patients were included in this study. The median age at ORN diagnosis was 61.1 yr (range, 32.8-84.9 yr). Of these 31 patients, 15 (48.4%) patients were initially treated medically. All 31 patients underwent surgery. Three (14.3%) of 21 patients treated with a free flap and 4 (50.0%) of 8 patients who underwent primary closure experienced recurrence. Cox regression analysis revealed that reconstruction with local tissue closure (P = .044) and ongoing treatment for active primary cancer (P = .022) were significant predictors of recurrence. The median overall survival from index surgery for ORN treatment was 83.9 mo. At 12-mo follow-up, 78.5% of patients were alive. CONCLUSION In this study, we assess the outcomes of our treatment approach, surgical debridement with vascularized reconstruction, on recurrence-free survival in patients with skull base ORN. Further studies with larger cohorts are needed to assess current treatment paradigms.

Abstract
OBJECTIVE Review long-term clinical and quality-of-life outcomes following free flap reconstruction for osteonecrosis. STUDY DESIGN Retrospective multi-institutional review. SETTING Tertiary care centers. METHODS Patients included those undergoing free flap reconstructions for osteonecrosis of the head and neck (N = 232). Data included demographics, defect, donor site, radiation history, perioperative management, diet status, recurrence rates, and long-term quality-of-life outcomes. Quality-of-life outcomes were measured using the University of Washington Quality of Life (UW-QOL) survey. RESULTS Overall flap success rate was 91% (n = 212). Relative to preoperative diet, 15% reported improved diet function at 3 months following reconstruction and 26% at 5 years. Osteonecrosis recurred in 14% of patients (32/232); median time to onset was 11 months. Cancer recurrence occurred in 13% of patients (29/232); median time to onset was 34 months. Results from the UW-QOL questionnaire were as follows: no pain (45%), minor or no change in appearance (69%), return to baseline endurance level (37%), no limitations in recreation (40%), no changes in swallowing following reconstruction (28%), minor or no limitations in mastication (29%), minor or no speech difficulties (93%), no changes in shoulder function (84%), normal taste function (19%), normal saliva production (27%), generally excellent mood (44%), and no or minimal anxiety about cancer (94%). CONCLUSION The majority of patients maintained or had advancement in diet following reconstruction, with low rates of osteonecrosis or cancer recurrence and above-average scores on UW-QOL survey suggesting good return of function and quality of life.

Abstract
BACKGROUND Osteoradionecrosis (ORN) of the maxilla is a rare disease. In contrast with a mandibular predominance, maxillary ORN has not been widely reported. OBJECTIVE To review clinical features, surgical treatments, and results of maxillary ORN and offer recommendations for surgical decision-making. MATERIAL AND METHODS We retrospectively reviewed medical records of maxillary ORN at our hospital between 2002 and 2017. Clinical data were collected, including age, sex, primary tumor characteristics, radiotherapy dose, clinical findings of maxillary ORN, and treatment outcomes. Descriptive statistics and multiple factors were analyzed. RESULTS Twenty-four patients were included for analysis. The primary symptoms of maxillary ORN were pain, trismus, pus, bone exposure, and skin fistula. Twenty (83.3%) patients were completely cured after single-operation. Thirteen patients underwent sequestrectomy, and the cure rate was 76.9% (10/13). Eleven patients received segmental osteotomy and flap reconstruction, with the cure rate of 90.9% (10/11). There was no significant statistical difference in the cure rate between these two groups (p = .596). CONCLUSIONS AND SIGNIFICANCE Compared with mandibular ORN, the surgical effect of maxillary lesions is better and the choice of operation methods can be relatively conservative. Both sequestrectomy and segmental osteotomy with flap reconstruction can achieve good results in appropriate conditions.

Novel Technique with Double Free Flap Design for Advanced Mandibular Osteoradionecrosis: A Case Series. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2020; 8:e3149.

Abstract
Advanced mandibular osteoradionecrosis is arguably among the most challenging cases for reconstructive head and neck surgeons. Several reconstructive methods for complex mandibular defects have been reported; however, for advanced mandibular osteoradionecrosis, a safe option that minimizes the risk of renewed fistulation and infections is needed. For this purpose, we present a new technique using a fascia-sparing vertical rectus abdominis musculocutaneous flap as protection for a vascularized free fibula graft (FFG). This technique also optimizes recipient site healing and functionality while minimizing donor site morbidity. Our initial experiences from a 4 patient case series are included. Mean operative time was 551 minutes (SD: 81 minutes). All donor sites were closed primarily. Mean time to discharge was 13 days (SD: 7 days), and mean time to full mobilization was 2 days (SD: 1 days). This double free flap technique completely envelops the FFG and plate with nonirradiated muscle. It allows for the transfer of an FFG without a skin island, thus avoiding the need for split skin graft closure. This results in faster healing and minimizes the risk of fibula donor site morbidity. The skin island of the vertical rectus abdominis musculocutaneous flap has the added benefit of providing intraoral lining, which minimizes contractures and trismus. Although prospective long-term studies comparing this approach to other double flap procedures are needed, we argue that this technique is an optimal approach to safeguard the mandibular FFG reconstruction against the inherent risks of renewed complications in irradiated unhealthy tissue.

Abstract
The implementation of radiotherapy in the multimodal treatment of advanced head and neck cancer has greatly improved survival rates. In some patients, however, this benefit comes at the potential expense of the tissue surrounding the primary site of malignancy. Osteoradionecrosis (ORN) of the facial bones, in particular the maxilla, is a debilitating complication of radiation therapy. Exposure to ionizing radiation results in devitalization of underlying bone with necrosis of adjacent soft tissue. Controversy surrounding appropriate early intervention in ORN persists and no consensus for clinical treatment has been established. In the present article, we review the pathophysiology of maxillary ORN and discuss the role of both conservative medical therapy and reconstruction.

Abstract
The authors reported a case of extensive maxillary osteoradionecrosis. The maxilla was resected and reconstructed with fibula musculocutaneous flap. It was the first reported that the osteoradionecrotic maxilla was reconstructed with free vascularized bone. The musculocutaneous flap might be a better choice of maxillary osteoradionecrosis reconstruction instead of the simple soft-tissue flap.

Abstract
Importance The clinical and financial implications of the timing of dental rehabilitation after a fibula free tissue transfer (FFTT) for osteoradionecrosis (ORN) and osteonecrosis (ON) of the mandible have yet to be established. Objective To compare the outcomes of primary implantation vs secondary implantation after FFTT for ORN and ON of the mandible. Design, Setting, and Participants A retrospective review was conducted of 23 patients at a single tertiary academic referral center undergoing primary implantation or secondary implantation after FFTT for ORN and ON from January 1, 2006, to November 10, 2015. Interventions All patients underwent FFTT with primary implantation (n = 12) or secondary implantation (n = 11). Main Outcomes and Measures Outcomes of FFTT, dental implantation, implant use, diet, speech, and disease-free survival were reviewed. Fixed unit costs were estimated based on the mean cost analysis. Results Twenty-three patients (7 women and 16 men; mean [SD] age, 62.4 [8.2] years [range, 24-81 years]) met the inclusion criteria. Of these, 18 had ORN and 5 had ON. Dental implantation was performed at the time of FFTT for 12 patients and was performed secondarily for 11 patients. There were a mean of 5.2 implants per patient performed, for a total of 121 implants. There was 1 complete flap failure in the primary implantation group. Neither flap nor implant complications were affected by the timing of the implantation. Overall, the implant survival rate was 95% (55 of 58) in the primary implantation group and 98% (62 of 63) in the secondary implantation group. Time from FFTT to abutment placement (primary implantation, 19.6 weeks; secondary implantation, 61.0 weeks) was significantly shorter after primary implantation (P < .001). There was no clinical difference in postoperative complications and implant outcomes for ORN vs ON. Improvement in speech and oral competence in the primary implantation group vs the secondary implantation group was not statistically significant, given an experiment-adjusted P = .001 set as significant (normal speech, 9 vs 3; P = .02; and normal oral competence, 9 vs 3; P = .02). Disease-free survival was 91% (20 of 22 patients) overall. Fixed unit (U) costs were 1.0 U for primary implantation and 1.24 U for secondary implantation. Conclusions and Relevance Patients undergoing primary implantation after FFTT for ORN and ON had a similar rate of complications compared with those undergoing secondary implantation. However, primary implantation allowed a faster return than secondary implantation to oral nutrition and prosthesis use. The fixed unit cost was reduced for those undergoing primary implantation. Although dental implantation was safe and effective in both groups, the decreased time to use and the decreased overall cost should prompt surgeons to consider primary implantation after FFTT for ORN and ON. Level of Evidence 3.

Abstract
INTRODUCTION Chronic osteomyelitis is characterized by compromised blood supply and eventual osteonecrosis. Definitive treatment requires aggressive resection of affected bone. The resultant defect poses a unique challenge to reconstructive surgeons. Much of the literature on craniofacial osteomyelitis focuses on infection eradication, rather than subsequent reconstruction. This article reports representative cases from our experience with free flap reconstruction for defects secondary to chronic osteomyelitis of the craniofacial skeleton. METHODS/RESULTS The authors selected 5 of the most difficult reconstructive cases of craniofacial osteomyelitis from our experience in a single tertiary referral institution with a follow-up of at least 6 months. Three of the 5 cases arose in the setting of previous head and neck cancer treated with resection and radiation therapy. One case had a previous surgical craniotomy complicated by osteomyelitis and multiple failed alloplastic reconstructions. The final case was due to multiple gunshots to the head, with subsequent cerebral and cranial abscess (>1000cc). In each case, the defect was successfully treated with free tissue transfer. Two cases required creation of recipient vessels with an arteriovenous loop. CONCLUSIONS Free tissue transfer provides a versatile and effective tool in the reconstruction of extensive craniofacial osteomyelitis defects. Furthermore, the addition of vascularized tissue can protect against further episodes of osteomyelitis. Finally, arteriovenous loops can be employed successfully when prior radiation and infection of the wound bed precludes the use of local recipient target vessels.

Abstract
Osteoradionecrosis (ORN) of the jaws is a pernicious complication of radiation therapy for head and neck tumours. This article aims to provide an update on data related to the definition, epidemiology, staging, and clinical and radiological findings of ORN of the jaws. Using certain keywords, an electronic search was conducted spanning the period from January 1922 to April 2014 to identify the available related investigations. Pooled data were then analysed. ORN is described as exposed irradiated bone that fails to heal over a period of 3 months without evidence of persisting or recurrent tumour. The prevalence of ORN varies in the literature. Several staging or scoring systems of ORN have been proposed. Clinical findings include ulceration or necrosis of the mucosa with exposure of necrotic bone. Radiological findings are not evident in the early stages of ORN. Furthermore ORN may not be apparent in imaging even when the disease is advanced. Taking into account the severity of ORN and the difficulties in diagnosing it early and accurately, the clinician should be aware of this complex entity in order to prevent its appearance or the development of more severe complications.

Abstract
BACKGROUND Osteoradionecrosis is the most dreadful complication after head and neck irradiation. Orocutaneous fistula makes patients difficult to eat food. Fibular free flap is the choice of the flap for mandibular reconstruction. Osteocutaneous flap can reconstruct both hard and soft tissues simultaneously. This study was to investigate the success rate and results of the free fibular flap for osteoradionecrosis of the mandible and which side of the flap should be harvested for better reconstruction. METHODS A total of eight consecutive patients who underwent fibula reconstruction due to jaw necrosis from March 2008 to December 2015 were included in this study. Patients were classified according to stages, primary sites, radiation dose, survival, and quality of life. RESULTS Five male and three female patients underwent operation. The mean age of the patients was 60.1 years old. Two male patients died of recurred disease of oral squamous cell carcinoma. The mean dose of radiation was 70.5 Gy. All fibular free flaps were survived. Five patients could eat normal diet after operation; however, three patients could eat only soft diet due to loss of teeth. Five patients reported no change of speech after operation, two reported worse speech ability, and one patient reported improved speech after operation. The ipsilateral side of the fibular flap was used when intraoral soft tissue defect with proximal side of the vascular pedicle is required. The contralateral side of the fibular flap was used when extraoral skin defect with proximal side of the vascular pedicle is required. CONCLUSIONS Osteonecrosis of the jaw is hard to treat because of poor healing process and lack of vascularity. Free fibular flap is the choice of the surgery for jaw bone reconstruction and soft tissue fistula repair. The design and selection of the right or left fibular is dependent on the available vascular pedicle and soft tissue defect sites.

Abstract
The use of a myomucosal flap from the buccinator muscle is a valuable reconstruction method for intraoral defects. In this paper, we report the clinical advantages of using a buccinator myomucosal flap for the treatment of partial mandibular defects caused by osteoradionecrosis. We implemented a buccinator myomucosal flap for the reconstruction of a partial mandibular defect in a 55-year-old man with tonsil cancer and partial mandibular defects caused by osteoradionecrosis. The total operating time was 90 minutes. Twelve months after the reconstruction, the patient remains free of disease. A buccinator myomucosal flap can be used for the reconstruction of partial mandibular defects caused by osteoradionecrosis. It is a reliable method for reconstructing small mandibular defects.

Abstract
BACKGROUND Osteoradionecrosis (ORN) of the mandible is not an uncommon complication after radiotherapy for head and neck cancers. Although definitive treatment has been confirmed as radical excision of the necrotic bone with simultaneous vascularized osteocutaneous flap reconstruction, it remains a unique challenge. In this study, we compare our results of reconstruction with free iliac and fibula flaps in flap survival, bony union, and postoperative complications. PATIENTS AND METHODS From 1986 to 2011, there were 153 mandibular ORN cases in our center that were treated with radical resection of the necrotic bone and reconstruction with either vascularized iliac (n=108) or fibula flaps (n=45). Data collected for analysis included patient demographics, flap survival rate, postoperative infection rate, nonunion/malunion rate, mean hospital stay, and antibiotics use. RESULTS All patients healed eventually without recurrence of ORN. However, we observed difference in the complication rate between the iliac flap group and fibula flap group. In the group with iliac flap reconstruction, patients required less days of hospital stay for intravenous antibiotics treatment postoperatively. The average days required for intravenous antibiotics in the iliac flap group were 10.46 (2.28) versus 16.09 (3.88) days in the fibula group (P<0.01). In the group with fibula flap reconstruction, 9 (20.0%) patients had subsequent neck infection due to healing problem, compared to 8 (7.4%) patients in the iliac flap group (P=0.04). In the iliac flap group, the nonunion and malunion rates were 4.6% and 2.8% respectively; whereas in the fibula group, the rates were 15.5% and 6.6%, respectively (P=0.04 and 0.36, respectively). CONCLUSIONS For ORN patients, vascularized iliac bone flap provides more reliable results compared to fibula flap. The merits of vascularized iliac flap include the following: (1) its natural curve mimics the shape of mandible and does not need osteotomy; (2) it offers more volume of bone that matches better to the native mandible to allow later osteointegration as well as faster bony union, due to the nature of being a membranous bone; and (3) it carries more abundant soft tissue to obliterate possible dead space. The only disadvantages are short pedicle and requiring special management of skin paddle, which can be overcome by training in microsurgery.

Abstract
INTRODUCTION Osteoradionecrosis (ORN) of the chest wall is a rare complication after whole-breast radiotherapy (RT). Herein, we report a case of ORN involving the underlying ribs following adjuvant whole-breast RT using standard fractionation and conduct a review of the literature. CASE REPORT A previously well 43-year-old female with right-sided, early-stage, node-negative breast cancer was treated with breast-conserving surgery. She subsequently underwent adjuvant whole-breast RT receiving 50 Gy in 25 fractions over 5 weeks using standard tangential photon fields with 6 MV photons followed by an electron boost of 10 Gy in 5 fractions according to International Commission on Radiation Units (ICRU) requirements. Eleven months after RT, the patient developed right lateral chest wall pain, with magnetic resonance imaging (MRI) demonstrating two fractures involving the underlying right fifth and sixth ribs associated with fatty marrow changes in the second to sixth ribs, thus raising the possibility of ORN. Treatments including hyperbaric oxygen, pentoxifylline and vitamin E were used with symptomatic improvements. There was demonstrable resolution on follow-up MRI at 2.5 years. CONCLUSION The incidence of ORN utilising modern RT techniques and standard fractionation is rare. Numerous treatments are available, with variable response rates. Emerging evidence of predictive gene profiling to estimate the risk of radiation sensitivity may assist in individualising preventative strategies to mitigate the risk of ORN.

Abstract
BACKGROUND The reconstruction of bilateral osteoradionecrosis (ORN) of mandibular defects using a single free bone flap is rarely performed because extensively radiated neck tissue with severe fibrosis is usually unsuitable for vascularized reconstruction. METHODS Thirty-one patients with nasopharyngeal carcinoma (NPC) underwent bilateral reconstruction of advanced ORN in the mandible using a single fibular osteocutaneous flap. Clinical factors associated with the operation were assessed, including classification of mandible defects, types of recipient vessels, perioperative complications, and postoperative outcomes. RESULTS All of the fibular osteocutaneous flaps survived completely, with the exception of 1 inner skin paddle that presented partial necrosis in a reconstruction of through-and-through defects. All patients experienced an improvement in cosmetic results 6 months after the reconstruction, whereas 23 patients experienced improved mouth opening compared to the preoperative condition. CONCLUSION Advanced bilateral ORN in patients with NPC could be synchronously reconstructed with a single fibular osteocutaneous flap. © 2015 Wiley Periodicals, Inc. Head Neck 38: E-E, 2016.

Abstract
Pathological mandibular fractures are rare, accounting for fewer than 2% of all fractures of the mandible. They could be defined as fractures that occur in regions where bone has been weakened by an underlying pathological process. Pathological fractures usually may follow surgical interventions such as third molar removal or implant placement, result from regions of osteomyelitis, osteoradionecrosis, and bisphosphonate-related osteonecrosis of the jaw, occur because of idiopathic reasons or be facilitated by cystic lesions, benign, malignant, or metastatic tumors. Pathological mandibular fractures may be challenging to treat because of their different etiology and peculiar local and general conditions, often requiring a more rigid fixation. In patients with poor medical conditions, simpler and more limited options may be preferred.

Abstract
Jaw osteoradionecrosis (ORN) is a common and serious complication of radiation therapy for head and neck cancers. Bone marrow mesenchymal stromal cells (BMMSCs) are multipotent postnatal stem cells and have been widely used in clinical therapies. In the present study, we generated the mandibular ORN model in swine using a combination of single-dose 25-Gy irradiation and tooth extraction. A typical ORN phenotype, including loss of bone regeneration capacity and collagen collapse with the obliteration of vessels, gradually appeared after irradiation. After autologous BMMSC transplantation, new bone and vessels were regenerated, and the advanced mandibular ORN was treated successfully. In summary, we developed a swine model of jaw ORN, and our results indicate that autologous BMMSC transplantation may be a promising therapeutic approach for ORN.

Abstract
PURPOSE The present study was undertaken to evaluate our recent experience with mandibular osteoradionecrosis (ORN) and to identify factors that contribute to its progress. PATIENTS AND METHODS The medical records of 114 patients who had been treated for ORN during a 16-year period (1989 to 2004) were reviewed. The patients were then divided into 2 groups according to their response to conservative treatment. Group 1 consisted of patients whose ORN resolved with conservative treatment (n = 47). Group 2 consisted of patients whose ORN was unresolved with conservative treatment or who had required radical resection of the involved tissue (n = 67). The information was obtained from the medical records of the patients and analyzed. RESULTS The patients whose ORN was associated with an early-stage tumor or preirradiation extraction had a favorable response to conservative treatment. However, those who had an advanced primary tumor, had continued smoking and drinking after radiotherapy, had received palliative radiotherapy or a radiation dose of more than 6,000 rads, and who had an orocutaneous fistula, a pathologic fracture, swelling, or trismus had a poor response to conservative treatment. In these latter cases, radical resection of the involved tissue proved useful. CONCLUSIONS The results of the present study have indicated that several factors (ie, the stage of the primary tumor, signs of ORN) can influence the progress of ORN. Our results suggest that radical resection is a useful method for treating mandibular ORN that does not respond to conservative treatment.

Abstract
PURPOSE Osteoradionecrosis (ORN) is a severe and devastating late complication of radiotherapy in patients with head and neck cancer. Management of ORN remains controversial and the current approach has been focused on debridement, systemic antibiotics, and eventually hyperbaric oxygen therapy for small and limited ORN. However, this conservative approach is ineffective in controlling extensive bone and soft-tissue necrosis. Microvascular composite flaps have been used in a variety of head and neck ablative surgeries but its use for the management of ORN has not been fully explored. MATERIALS AND METHODS From 1999 to 2002, 5 patients with refractory ORN of the mandible underwent radical resection and reconstruction with immediate microvascular-free fibular composite flap. All patients had been treated initially with conservative procedures and hyperbaric oxygen therapy. RESULTS All patients had initially successful vascularized reconstruction by clinical examination with minimal postoperative morbidity. One patient had complete flap loss at 20 days due to orocutaneous fistula and infection. CONCLUSIONS Radical resection followed by microvascular composite flap reconstruction is a reliable procedure in the management of patients with extensive ORN of the mandible.

Abstract
CONCLUSION All bones of the facial skeleton and spine are susceptible to osteomyelitis due to various predisposing conditions. Current radiological tools are sufficient to provide adequate diagnosis. Treatment can be conservative resection of the diseased bone with adequate clearance in all cases except in cases of osteomyelitis due to osteoradionecrosis (ORN) where resection has to be more radical. OBJECTIVE In today's antibiotic era, osteomyelitis in the head and neck is a rare occurrence. Dealing with osteomyelitis in head and neck bones is not the same as in other bones of the body due to the nature of the bones, complex anatomy of the region, and esthetics. Our purpose was to analyze the behavior of osteomyelitis in the head and neck bones and its management. MATERIALS AND METHODS A total of 84 cases of osteomyelitis in head and neck were reviewed in a 10-year period. Pus for culture, antibiotic sensitivity, and radiology were the main investigations. A medical line of treatment was effective in acute cases. Surgery was opted for in chronic cases. RESULTS Mandible, frontal bone, cervical spine, maxilla, temporal bones, and nasal bones were involved, in descending order of frequency, i.e. the mandible was the most common bone affected. Nine patients were diagnosed as having acute osteomyelitis (11%); 75 were diagnosed as having chronic osteomyelitis (89%). Radiation-induced ORN leading to osteomyelitis was the most common cause of osteomyelitis of the mandible (13 of the 32 cases; 41%). Odontogenic infections and chronic sinusitis each gave rise to osteomyelitis in 3 of 10 cases (30%) of the patients with osteomyelitis of the maxilla. Chronic sinusitis was the main cause of frontal bone osteomyelitis in all 20 cases (100%). Tuberculosis (10 of 15 cases; 67%) and malignancy (5 of 15 cases; 33%) were the main predisposing factors in cervical spine osteomyelitis. Malignant external otitis (MEO) with diabetes mellitus was an underlying factor in all four cases of osteomyelitis of the temporal bone. Of the 18 patients with a diagnosis of ORN, the mandible was found to be the most susceptible bone (13 cases; 72%), followed by the maxilla (four cases; 22%) and cervical spine (1 case). Acute osteomyelitis responded to antibiotics. Sequestrectomy was carried out in all chronic cases but in cases of ORN more radical surgery was performed.

Abstract
INTRODUCTION Osteoradionecrosis of the mandible is a serious complication following radiotherapy for head and neck cancer. Reconstructive procedures in the head and neck region use a wide range of flaps for defect closure. The methods range from local, mostly myocutaneous flaps and skin grafts to free microsurgical flaps to ensure a satisfactory functional and aesthetic result. Moreover, the donor site defect needs to be closed, with as little as possible functional or aesthetic impairment. PATIENT AND METHOD A 60-year-old male is presented with a history of squamous cell carcinoma of the left lower lip and chin area in whom the tumour was resected and treated by adjuvant radiotherapy. The follow-up was complicated by chronic inflammation of the left mandibular body as a sequel of radiotherapy; it resulted with partial bone destruction, and soft tissue dehiscence. He was admitted for repair and treatment of the infected mandibular osteoradionecrosis. A supraclavicular artery island flap was used to close the mandibular soft tissue defect. CONCLUSION The shoulder provides a relatively good skin texture and match to provide cover and lining for defects in the lower part of the face, in combination with minor donor site morbidity.

Abstract
OBJECTIVE Treatment of mandibular osteoradionecrosis is always a therapeutic challenge. The aim of this article is to evaluate the interest of fibula free flap for mandible reconstruction after radical excision of osteoradionecrotic lesions. MATERIAL AND METHODS Six consecutives cases of extensive osteoradionecrosis of the mandible were treated with fibula free flap reconstruction. We report a meticulous analysis of the cosmetic and functional results. RESULTS All vascularized fibula osteocutaneous flaps transplanted were successful. Median hospital stay was 32 days. At 6 months, functional results (swallowing, mouth opening and speech) were good. All patients had sufficient oral intake and a comprehensible speech with just two patients requiring a soft diet and 1 patient retaining a moderate trismus. DISCUSSION Extensive mandibular osteoradionecrosis requires a radical surgical treatment. Fibula free flap is the best solution for mandible reconstruction in this situation. This technique allows good functional results. CONCLUSION Fibula free flap is the method of choice for mandible reconstruction after radical treatment of osteoradionecrosis.

Abstract
OBJECTIVE To evaluate the role of the osteocutaneous radial forearm free flap (OCRFFF) in the treatment of mandibular osteoradionecrosis (ORN). STUDY DESIGN AND SETTING Retrospective case review of patients who underwent OCRFFF oromandibular reconstruction after resection of nonviable tissue at an academic tertiary care center because of ORN. Patients with reconstructions other than OCRFFF were excluded from this study. RESULTS Nine patients underwent a composite oromandibular resection for ORN with a reconstruction using an OCRFFF between April 1998 and February 2003. All patients had failed previous less aggressive surgical and medical management of the ORN. Mean follow-up was 36 months (range, 14-67 months). There were no flap failures or significant immediate postoperative or long-term complications observed. All patients had successful restoration of mandibular integrity and continuity, with 100% success rate of stabilization of ORN. All patients were able to tolerate PO diet, with only one third having to supplement their diet with gastrostomy feedings, compared with 89% gastrostomy dependence preoperatively. CONCLUSIONS Primary or adjuvant radiotherapy for head and neck malignancies can result in ORN of the mandible. This difficult problem often requires surgical intervention. In our experience, the OCRFFF can be successfully used for oromandibular reconstruction, even in the setting of the heavily radiated tissue with excellent postoperative outcomes. SIGNIFICANCE This is the first study that demonstrates the efficacy of the OCRFFF as a treatment of mandibular ORN.
