RESUMO
INTRODUCTION: Chronic rhinosinusitis (CRS) can be associated with tumors involving the maxillary sinus, but outcomes after undergoing maxillectomy with free flap reconstruction remain unclear. METHODS: A retrospective analysis of medical records was performed to evaluate evidence of CRS in patients who underwent maxillectomy with free flap reconstruction at a single tertiary care academic institution from 2013 through 2020. RESULTS: Eighty-four patients were assessed. Nineteen (22.6%) patients were diagnosed with CRS after surgery, 23 (27.4%) patients were treated for sinus symptoms, and 49 (58.3%) had radiographic evidence of sinus inflammation for more than 6 months. Risk factors for requiring sinus treatment included adjuvant or neoadjuvant chemotherapy (p = 0.002) and pre-operative use of sinus medication (p < 0.001). Radiographic evidence of sinusitis 6 months after surgery is also closely associated with sinusitis treatment (p = 0.051). CONCLUSIONS: CRS may be underdiagnosed in patients undergoing maxillectomy with microvascular reconstruction. Further evaluation into patient sinus disease and symptoms following neoplastic surgery may lead to a higher quality of life in some long-term survivors.
RESUMO
INTRODUCTION: Management of the neck in oral cavity squamous cell carcinoma (OCSCC) is essential to oncologic control and survival. The rates of lymph node metastasis (LNM) vary based on oral cavity tumor site and stage and influence treatment decisions. The aim of this paper was to describe clinical LNM for different tumor subsites and stages of surgically managed OCSCC. METHODS: We conducted a retrospective analysis of 25,846 surgically managed OCSCC patients from the National Cancer Database (NCDB) stratified by tumor subsite and clinical T-stage. For cN + patients, rates of pathologic LNM and absence of pathologic LNM were determined. For cN0 patients, outcomes included the rates of elective neck dissection (END) and occult LNM and predictors of occult LNM determined by a multivariable logistic regression model. RESULTS: A total of 25,846 patients (59.1% male, mean age 61.9 years) met inclusion criteria with primary tumor sites including oral tongue (50.8%), floor of mouth (21.2%), lower alveolus (7.6%), buccal mucosa (6.7%), retromolar area (4.9%), upper alveolus (3.6%), hard palate (2.7%), and mucosal lip (2.5%). Among all sites, clinical N+ rates increased with T-stage (8.9% T1, 28.0% T2, 51.6% T3, 52.5% T4); these trends were preserved across subsites. Among patients with cN + disease, the overall rate of concordant positive pathologic LNM was 80.1% and the rate of discordant negative pathologic LNM was 19.6%, which varied based on tumor site and stage. In the overall cohort of cN0 patients, 59.9% received END, and the percentage of patients receiving END increased with higher tumor stage. Occult LNM among those cN0 was found in 25.1% of END cases, with the highest rates in retromolar (28.8%) and oral tongue (27.5%) tumors. Multivariable regression demonstrated significantly increased rates of occult LNM for higher T stage (T2 OR: 2.1 [1.9-2.4]; T3 OR: 3.0 [2.5-3.7]; T4 OR: 2.7 [2.2-3.2]), positive margins (OR: 1.4 [1.2-1.7]), and positive lymphovascular invasion (OR: 5.1 [4.4-5.8]). CONCLUSIONS: Management of the neck in OCSCC should be tailored based on primary tumor factors and considered for early-stage tumors.

BACKGROUND: Concerns regarding iatrogenic femur fracture may deter adoption of the anterolateral thigh osteomyocutaneous (ALTO) flap as an alternative reconstructive technique for large composite defects of the head and neck. We describe the evolution of our experience with this flap and the lessons learned in femur management. METHODS: Records from a prospective database (July 2009-January 2020) were reviewed to identify patients with composite osseous free tissue reconstructions. Venous thromboembolic events (VTE), femur fracture, estimated blood loss (EBL), procedure time, blood transfusions, and length of stay (days) were compared for ALTO flaps prior to and after the adoption of intramedullary fixation protocol. RESULTS: ALTO represented 10.5% (n = 23) of total osseus (n = 219) flaps. For large composite reconstructions with either ALTO flap, double flap (n = 2), or subscapular mega flaps (n = 14), ALTO flaps were most frequently used (59%, n = 23/59). There were no differences in operative time prior to and after implementation of prophylactic fixation [median (range): 5.4 (1.7-19.2) vs. 5.8 (1.7-15.0), p = .574]. Additionally, there were no differences in VTE, femur fracture, EBL, blood transfusion, or length of stay (p > .05) with adoption of prophylactic intramedullary fixation. CONCLUSIONS: The ALTO flap represents a useful tool to consider in the armamentarium of reconstructive options for large through and through defects of the head and neck. In our experience, the ALTO flap is a reasonable alternative to subscapular or double flap reconstructions and especially in the setting of unusable fibular flaps or when bone need exceeds that available from the scapula.

BACKGROUND: Sentinel lymph node biopsy (SLNB) has not been studied for invasive melanomas treated with Mohs micrographic surgery using frozen-section MART-1 immunohistochemical stains (MMS-IHC). The primary objective of this study was to assess the accuracy and compliance with National Comprehensive Cancer Network (NCCN) guidelines for SLNB in a cohort of patients who had invasive melanoma treated with MMS-IHC. METHODS: This retrospective cohort study included all patients who had primary, invasive, cutaneous melanomas treated with MMS-IHC at a single academic center between March 2006 and April 2018. The primary outcomes were the rates of documenting discussion and performing SLNB in patients who were eligible based on NCCN guidelines. Secondary outcomes were the rate of identifying the sentinel lymph node and the percentage of positive lymph nodes. RESULTS: In total, 667 primary, invasive, cutaneous melanomas (American Joint Committee on Cancer T1a-T4b) were treated with MMS-IHC. The median patient age was 69 years (range, 25-101 years). Ninety-two percent of tumors were located on specialty sites (head and/or neck, hands and/or feet, pretibial leg). Discussion of SLNB was documented for 162 of 176 (92%) SLNB-eligible patients, including 127 of 127 (100%) who had melanomas with a Breslow depth >1 mm. SLNB was performed in 109 of 176 (62%) SLNB-eligible patients, including 102 of 158 melanomas (65%) that met NCCN criteria to discuss and offer SLNB and 7 of 18 melanomas (39%) that met criteria to discuss and consider SLNB. The sentinel lymph node was successfully identified in 98 of 109 patients (90%) and was positive in 6 of those 98 patients (6%). CONCLUSIONS: Combining SLNB and MMS-IHC allows full pathologic staging and confirmation of clear microscopic margins before reconstruction of specialty site invasive melanomas. SLNB can be performed accurately and in compliance with consensus guidelines in patients with melanoma using MMS-IHC.

PURPOSE: To evaluate the role of elective neck dissection (END) and of adjuvant radiation (aRT) in polymorphous adenocarcinoma (PAC), previously known as polymorphous low-grade adenocarcinoma (PLGA). METHODS: Retrospective cohort study of patients in the National Cancer Database with a histology of PAC (coded as PLGA) at a head and neck site diagnosed between 2004 and 2015. Multivariable Cox proportional hazard modeling was used to assess overall survival in the overall population, and in sub-analyses of clinically N0 disease, positive resection margins, and late stage disease. RESULTS: A total of 922 patients [66.8% female; mean (SD) age, 60.9 (13.9) years] met inclusion criteria. 74.7% of patients received surgery alone, and 18.0% received surgery and aRT. Only 7.6% of patients with clinically N0 disease received an END, with 10.6% of these having at least one positive node. END did not have a survival benefit compared to no END [HR 1.28 (0.61-2.68)]. Compared to surgery alone, aRT did not have significantly increased survival in the overall population or in late stage [HR 0.68 (0.39-1.19) and HR 0.46 (0.18-1.22), respectively]. On sub-analysis of patients with positive resection margins, aRT had a significant survival benefit compared to surgery alone [HR 0.37 (0.14-0.99)]. CONCLUSION: PAC is a rare, slow-growing malignant tumor typically treated with surgical excision, with undefined indications for END or aRT. Our findings show END to not have a benefit to overall survival. In patients with positive resection margins, there was a survival benefit for aRT.

Large defects that comprise both the maxilla and mandible prove to be difficult reconstructive endeavors and commonly require two free tissue transfers. Three cases are presented to discuss an option for simultaneous reconstruction of maxillary and mandibular defects using a single osteocutaneous fibula free flap. The first case describes a 16-year-old male with a history of extensive facial trauma sustained in a boat propeller accident resulting in a class IId maxillary and 5 cm mandibular defect status post three failed reconstructive surgeries; the second, a 33-year-old male with recurrent rhabdomyosarcoma of the muscles of mastication with resultant hemi-mandibulectomy and class IId maxillary defects; and lastly, a 48-year-old male presenting after a failed scapular free flap to reconstruct defects resulting from a self-inflicted gunshot wound, which included a 5 cm defect of the right mandibular body and 4.5 cm defect of the inferior maxillary bone. In all cases, a single osteocutaneous fibula free flap was used in two bone segments; one to obturate the maxillary defect and restore alveolar bone and the other to reconstruct the mandibular defect. The most recent patient was able to undergo implantable dental rehabilitation. Postoperatively, the free flaps were viable and masticatory function was restored in all patients during a follow-up range of 2-4 years.

The anterior lateral thigh osteomyocutaneous (ALTO) free flap represents a unique reconstructive option for patients who are otherwise not good candidates for traditional free flaps to repair a through-and-through defect of the head and neck. We report the case of a patient with squamous cell carcinoma of the oral cavity who had undergone composite segmental mandibulectomy with a resultant through-and-through defect. The patient was not a candidate for fibula free flap (FFF) reconstruction owing to the presence of bilaterally dominant peroneal arteries. The patient underwent reconstruction with a single free tissue ALTO flap, with a good viable flap postoperatively. The patient did not experience any major or minor surgical complications and has been living with no evidence of disease. The ALTO free flap could be an effective flap in the reconstruction of through-and-through defects of the mandible for patients who are not candidates for FFF-based reconstruction.

BACKGROUND: Given the rarity of parotid cancer, there is relatively few data published regarding outcomes. Utilizing the large sample population of the National Cancer Database (NCDB), we aim to examine the relationship between two key social determinants of health, demographics and socioeconomic status (SES), and parotid malignancy survival rates. METHODS: Our analytic sample consists of patients with a diagnosis of primary malignancy of the parotid gland between 2004 and 2012 in the NCDB. We used univariable and multivariable Cox proportional hazard models to evaluate the relationship between overall survival rate and two key social determinants of health: demographics and SES. RESULTS: 15,815 cases met inclusion criteria. Average age was 60.1â¯years and 8255 were male (52.2%). Median overall survival was 121â¯months with 5-year overall survival of 67.4%. Male sex and older age at diagnosis were associated with poorer overall survival (pâ¯<â¯0.0001). We found that Asian Americans compared to whites had better overall survival (HR 0.75; 95% CI [0.58-0.95]). Black patients had improved survival compared to whites on univariate (HR 0.71; 95% CI [0.64-0.79]); but not multivariate analysis. Hispanic ethnicity and higher education level were protective (HR 0.76 95% CI [0.63-0.91] and HR 0.84 95% CI [0.74-0.96], respectively). We found no significant survival association based on income level. CONCLUSION: In this national sample of patients with parotid malignancy, a rare form of cancer, we found a significant correlation between important social determinants of health and overall survival rate. Females, Asian-Americans, Hispanics, and patients with higher education level have better overall survival.

PURPOSE: Pectoralis major muscle flaps (PMMF) are a commonly used reconstructive modality to repair head and neck defects. As the use of free flap reconstruction is increasingly practiced in the head and neck, the role of the PMMF may be changing as well. This study sought to analyze indications and outcomes for PMMF following head and neck resections from one surgeon's experience. MATERIALS AND METHODS: Retrospective review from December 1, 2013 through September 30, 2017 at a tertiary care academic medical center. Indications for the PMMF were examined as well as surgical outcomes. Basic demographic data, patient head and neck cancer history, history of radiation and/or chemotherapy, and history of previous reconstructive procedures were obtained and compared across all subjects. RESULTS: Forty patients underwent a PMMF within the designated time frame. The majority of patients were male (83%) and the average age was 65 years (range 55.4-74.6 years). Of the 40 cases, 9 of the PMMFs were performed as primary reconstruction of the defect. In the remaining 31 cases, these flaps were utilized as a secondary reconstructive option following fistula formation (13), dehiscence (6), need for an additional flap for recurrent disease (6) infection (4), or major bleeding (2). In every case that it was utilized, the PMMF was the definitive reconstruction. Within the same time frame, 429 free flaps were performed by the same surgeon, with an average of 125 free flaps performed yearly. The rate of total flap failure overall was 3.9%. The other failed free flap reconstructive options used besides a PMMF were secondary free flaps (11), local wound care (4), or obturator placement (2). The secondary pectoralis flaps occurred following 7.2% of free flaps with total or partial failure that were performed within the same time range. The indications for the PMMF did not change or evolve during the time frame of the study. CONCLUSIONS: Although free flaps were performed with far greater frequency than PMMFs at our institution, the PMMF demonstrated continued utility as a secondary reconstructive option. For a surgeon who performs a high volume of free flaps, preservation of the pectoralis muscle and associated vasculature for possible later secondary reconstruction should be considered due to its strong efficacy.

OBJECTIVE: In the setting of current national healthcare reform, it becomes especially relevant to understand the current state of healthcare disparities with regards to insurance status. To determine the impact of payer status on survival in parotid malignancy, we utilized the National Cancer Database (NCDB). STUDY DESIGN: Retrospective database review. SETTING: National Cancer Database (2004-2012). SUBJECTS AND METHODS: The NCDB was queried for cases of primary malignancy of the parotid gland between 2004 and 2012. The impact of payer status on overall survival was evaluated, as well as the relationship of insurance status with patient and tumor variables. RESULTS: 15,815 cases met inclusion criteria. A majority had private insurance (47.8%), followed by Medicare (40.9%), Medicaid (5.0%), uninsured (3.2%) and other government sources (1.3%). Medicare patients had the lowest 5 and 10-year survival rates (50.7% (95% CI [49.3-52.1]) and 27.8% (95% CI [25.0-30.9]), respectively). On multivariable analysis, uninsured, Medicare, and Medicaid patients had worse overall survival than the privately insured (HR 1.42, 95% CI [1.17-1.74]; HR 1.29, 95% CI [1.17-1.42]; HR 1.36, 95% CI [1.13-1.62], respectively). Uninsured and Medicaid patients were more likely than the privately insured to present with advanced stage disease, nodal metastasis and longer times to treatment following diagnosis. CONCLUSION: In parotid malignancy, uninsured, Medicaid, and Medicare patients have worse survival outcomes compared to those with private insurance. Uninsured and Medicaid patients also present with more advanced stage disease and have increased wait times before definitive treatment is initiated.

BACKGROUND: Transoral surgical techniques for oropharyngeal tumors have been widely accepted, yet often results in a significant functional deficit. Current reports on the safety, feasibility, and swallowing performance after microvascular reconstruction are limited to small volume case series. MATERIALS AND METHODS: Retrospective review of 42 consecutive patients, between December 2013 and May 2016, who underwent transoral robotic surgery oropharyngectomy followed by microvascular reconstruction. RESULTS: Swallowing outcomes postoperatively resulted in 39 (93%) of patients tolerating oral intake postoperatively, with 13 (87%) of 15 patients at 1-year follow-up consuming an entirely oral diet. Thirty-eight (95%) of 40 patients who underwent a tracheostomy at the time of surgery were ultimately decannulated. No patients experienced complete flap failure in the current study. CONCLUSIONS: Minimally invasive transoral surgical techniques have offered the opportunity to minimize surgical morbidity and potentially deintensify adjuvant therapies. Reconstructive options have evolved to match surgical advances seen with robotic surgeries of oropharyngeal cancers. Microvascular reconstruction has been indicated in select patients including those with extensive soft palate resection, primary tumor abutment of the medial pterygoid musculature, exposure of internal carotid artery vasculature, prior radiation therapy, or a significant defect of the oropharyngeal sphincter. Select patients, based on previously identified criteria, were preoperatively identified as suitable candidates for microvascular reconstruction of oropharyngeal defects. This study demonstrates that complex transoral robotic surgical defects are amenable to microvascular reconstructive in carefully selected patients.

PURPOSE: Immunosuppressed solid organ transplant recipients (SOTRs) have an increased risk of developing cutaneous squamous cell carcinomas (cSCCs) with metastatic potential. This study sought to determine the rate of regional lymph node involvement in a large cohort of solid organ transplant patients with cutaneous head and neck squamous cell carcinoma. MATERIALS AND METHODS: A retrospective chart review was performed on solid organ transplant patients with head and neck cutaneous squamous cell carcinoma treated at a tertiary academic medical center from 2005 to 2015. RESULTS: 130 solid organ transplant patients underwent resection of 383 head and neck cutaneous squamous cell carcinomas. The average age of the patient was 63. Seven patients (5%) developed regional lymph node metastases (3 parotid, 4 cervical lymph nodes). The mean time from primary tumor resection to diagnosis of regional lymphatic disease was 6.7months. Six of these patients underwent definitive surgical resection followed by adjuvant radiation; one patient underwent definitive chemoradiation. 6 of the 7 patients died of disease progression with a mean survival of 15months. The average follow up time was 3years (minimum 6months). CONCLUSIONS: Solid organ transplant recipients with cutaneous squamous cell carcinoma of the head and neck develop regional lymph node metastasis at a rate of 5%. Regional lymph node metastasis in this population has a poor prognosis and requires aggressive management and surveillance.

OBJECTIVE: Mandibular plate reconstruction (MPR) is often indicated after tumor ablation, osteoradionecrosis excision, and traumatic bone loss to restore oral functionality and facial cosmetics. There are limited analyses identifying risk factors that lead to plate infection (PIn), exposure, and removal ("plate complications"). STUDY DESIGN: Retrospective cohort study. SETTING: Academic tertiary medical center. METHODS: Patients who underwent MPR from 2013 to 2022 were identified. Risk factors for plate complications were analyzed based on demographic, clinical, intraoperative, and postoperative factors. Multivariable analysis was conducted with logistic regression. Survival analysis was conducted with a Cox model. RESULTS: Of the 188 patients analyzed, 48 (25.5%) had a plate complication [infection: 22 (11.7%); exposure: 23 (12.2%); removal: 35 (18.6%)]. Multivariate analysis revealed predictive associations between at least 1 plate complication and the following variables: smoking status, soft tissue defect size, number of plates, average screw length, and various postoperative complications. Other associations approached the threshold for significance. Prior and adjuvant radiation therapy, type of free flap, stock versus custom plates, and perioperative antibiotic prophylaxis regimens were not associated with plate complications. No plate complication was independently associated with lower overall survival. PIn (hazard ratio, HR: 7.99, confidence interval, CI [4.11, 15.54]) and exposure (HR: 3.56, CI [1.79, 7.08]) were independently associated with higher rates of plate removal. CONCLUSION: Plate complications are relatively common after MPR. Smoking history, specific disease characteristics, hardware used during surgery, and postoperative complications may help identify higher-risk patients, but additional larger-scale studies are needed to validate our findings and resolve discrepancies in the current literature.
RESUMO
BACKGROUND: Transoral robotic surgery (TORS) for oropharyngeal malignancy optimizes oncologic outcomes while preserving functionality. This study identifies patterns of functional recovery after TORS with free flap reconstruction (FFR). METHODS: Retrospective cohort study at a tertiary care center of patients with primary oropharyngeal tumors treated with TORS with FFR between 2010 and 2022. Patients were categorized into: adjuvant chemoradiation or radiation, or no adjuvant therapy (NAT). Functional outcomes were measured by functional oral intake scale (FOIS). RESULTS: 241 patients were included. FOIS declined at first postoperative appointment (median = 7.0 to 2.0, IQR = [7.0, 7.0], [2.0, 4.0]), and progressively improved to 6.0 (5.0, 6.0) after 1 year, with NAT having the highest FOIS (7.0, p < 0.05). Predictors of poor long-term FOIS included RT and hypoglossal nerve (CN XII) involvement (p < 0.05). CONCLUSIONS: TORS with FFR leads to good long-term function with minimal intake restrictions. Radiation therapy and CN XII involvement increase risk of worse functional outcomes.

BACKGROUND: To develop machine learning (ML) models predicting unplanned readmission and reoperation among patients undergoing free flap reconstruction for head and neck (HN) surgery. METHODS: Data were extracted from the 2012-2019 NSQIP database. eXtreme Gradient Boosting (XGBoost) was used to develop ML models predicting 30-day readmission and reoperation based on demographic and perioperative factors. Models were validated using 2019 data and evaluated. RESULTS: Four-hundred and sixty-six (10.7%) of 4333 included patients were readmitted within 30 days of initial surgery. The ML model demonstrated 82% accuracy, 63% sensitivity, 85% specificity, and AUC of 0.78. Nine-hundred and four (18.3%) of 4931 patients underwent reoperation within 30 days of index surgery. The ML model demonstrated 62% accuracy, 51% sensitivity, 64% specificity, and AUC of 0.58. CONCLUSION: XGBoost was used to predict 30-day readmission and reoperation for HN free flap patients. Findings may be used to assist clinicians and patients in shared decision-making and improve data collection in future database iterations.

Importance: The utility of preoperative circulating tumor tissue-modified viral human papillomavirus DNA (TTMV-HPV DNA) levels in predicting human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma (HPV+ OPSCC) disease burden is unknown. Objective: To determine if preoperative circulating tumor HPV DNA (ctHPVDNA) is associated with disease burden in patients with HPV+ OPSCC who have undergone transoral robotic surgery (TORS). Design, Setting, and Participants: This cross-sectional study comprised patients with HPV+ OPSCC who underwent primary TORS between September 2021 and April 2023 at one tertiary academic institution. Patients with treatment-naive HPV+ OPSCC (p16-positive) and preoperative ctHPVDNA levels were included, and those who underwent neck mass excision before ctHPVDNA collection were excluded. Main Outcomes and Measures: The main outcome was the association of increasing preoperative ctHPVDNA levels with tumor size and lymph node involvement in surgical pathology. The secondary outcome was the association between preoperative ctHPVDNA levels and adverse pathology, which included lymphovascular invasion, perineural invasion, or extranodal extension. Results: A total of 70 patients were included in the study (65 men [93%]; mean [SD] age, 61 [8] years). Baseline ctHPVDNA levels ranged from 0 fragments/milliliter of plasma (frag/mL) to 49â¯452 frag/mL (median [IQR], 272 [30-811] frag/mL). Overall, 58 patients (83%) had positive results for ctHPVDNA, 1 (1.4%) had indeterminate results, and 11 (15.6%) had negative results. The sensitivity of detectable ctHPVDNA for identifying patients with pathology-confirmed HPV+ OPSCC was 84%. Twenty-seven patients (39%) had pathologic tumor (pT) staging of pT0 or pT1, 34 (49%) had pT2 staging, and 9 patients (13%) had pT3 or pT4 staging. No clinically meaningful difference between detectable and undetectable preoperative ctHPVDNA cohorts was found for tumor size or adverse pathology. Although the median preoperative ctHPVDNA appeared to be higher in pT2 through pT4 stages and pN1 or pN2 stages, effect sizes were small (pT stage: η2, 0.002 [95% CI, -1.188 to 0.827]; pN stage: η2, 0.043 [95% CI, -0.188 to 2.600]). Median preoperative log(TTMV-HPV DNA) was higher in active smokers (8.79 [95% CI, 3.55-5.76]), compared with never smokers (5.92 [95% CI, -0.97 to 1.81]) and former smokers (4.99 [95% CI, 0.92-6.23]). Regression analysis did not show an association between tumor dimension or metastatic lymph node deposit size and preoperative log(TTMV-HPV DNA). After univariate analysis, no association was found between higher log(TTMV-HPV DNA) levels and adverse pathology. Conclusions and Relevance: In this cross-sectional study, preoperative ctHPVDNA levels were not associated with disease burden in patients with HPV+ OPSCC who underwent TORS.

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.

Importance: Closure technique for optimization of postoperative and functional outcomes following salvage laryngectomy remains an area of debate among head and neck surgeons. Objective: To investigate the association of salvage laryngectomy closure technique with early postoperative and functional outcomes. Design, Setting, and Participants: This retrospective cohort study included patients from 17 academic, tertiary care centers who underwent total laryngectomy with no or limited pharyngectomy after completing a course of definitive radiotherapy or chemoradiotherapy with curative intent between January 2011 and December 2016. Patients with defects not amenable to primary closure were excluded. Data were analyzed from February 14, 2021, to January 29, 2024. Exposures: Total laryngectomy with and without limited pharyngectomy, reconstructed by primary mucosal closure (PC), regional closure (RC), or free tissue transfer (FTT). Main Outcomes and Measures: Patients were stratified on the basis of the pharyngeal closure technique. Perioperative and long-term functional outcomes were evaluated with bivariate analyses. A multivariable regression model adjusted for historical risk factors for pharyngocutaneous fistula (PCF) was used to assess risk associated with closure technique. Relative risks (RRs) with 95% CIs were determined. Results: The study included 309 patients (256 [82.8%] male; mean age, 64.7 [range, 58.0-72.0] years). Defects were reconstructed as follows: FTT (161 patients [52.1%]), RC (64 [20.7%]), and PC (84 [27.2%]). A PCF was noted in 36 of 161 patients in the FTT group (22.4%), 25 of 64 in the RC group (39.1%), and 29 of 84 in the PC group (34.5%). On multivariable analysis, patients undergoing PC or RC had a higher risk of PCF compared with those undergoing FTT (PC: RR, 2.2 [95% CI, 1.1-4.4]; RC: RR, 2.5 [95% CI, 1.3-4.8]). Undergoing FTT was associated with a clinically meaningful reduction in risk of PCF (RR, 0.6; 95% CI, 0.4-0.9; number needed to treat, 7). Subgroup analysis comparing inset techniques for the RC group showed a higher risk of PCF associated with PC (RR, 1.8; 95% CI, 1.1-3.0) and predominately pectoralis myofascial flap with onlay technique (RR, 1.9; 95% CI, 1.2-3.2), but there was no association of pectoralis myocutaneous flap with cutaneous paddle interposition with PCF (RR, 1.2; 95% CI, 0.5-2.8) compared with FTT with cutaneous inset. There were no clinically significant differences in functional outcomes between the groups. Conclusion and Relevance: In this study of patients with limited pharyngeal defects, interpositional fasciocutaneous closure technique was associated with reduced risk of PCF in the salvage setting, which is most commonly achieved by FTT in academic practices. Closure technique was not associated with functional outcomes at 1 and 2 years postoperatively.

BACKGROUND: Few standardized methods exist for evaluating the postoperative outcomes of osteocutaneous free flaps. We propose an anatomic-based scoring system for midface free flap reconstruction. METHODS: One hundred and twelve patients across four institutions underwent osteocutaneous reconstruction of the midface. Postoperative scans were scored based on the number of independent osseous subunits reconstructed (Subunit Score), the number of different bony appositions with bony contact (Contact Score), and the number of osseous segments in anatomic position (Position Score). These were added together to create a Total Score. RESULTS: Osteocutaneous radial forearm flaps had the lowest Subunit Score (p = 0.001). Fibula flaps had the highest Contact Score (p = 0.0008) and Position Score (p = 0.001). Virtual surgical planning was associated with an increased Subunit Score (p = 0.02) and Total Score (p = 0.04). CONCLUSIONS: We propose a novel scoring system for osseous midface reconstruction based on postoperative imaging scans. This can help guide management decisions and create a common language to compare outcomes.
