RESUMEN

BACKGROUND: Head and neck osteoradionecrosis (ORN) of the midface requiring free flap (FF) reconstruction is uncommon. This multi-institutional study was designed to review outcomes for this rare patient population. METHODS: Retrospective multi-institutional review of FF reconstruction for midface ORN (2005-2022; n = 54). RESULTS: The FF survival rate was 87% (n = 54). Patients were less likely to be tolerating a regular diet at 3 months postoperative if they had a preoperative history of prior head and surgery (80% vs. 95%; p = 0.02), a pathologic fracture (50% vs. 90%; p = 0.04), exposed bone intraorally (43% vs. 94%; p = 0.002), or a fistula (67% vs. 96%; p = 0.03). Mean albumin was higher in patients whose FF survived (3.6 ± 0.5 vs. 2.7 ± 1.4; p = 0.03). Patients with low prealbumin were more likely to undergo a hematoma evacuation (27% vs. 0%; p = 0.02). CONCLUSION: In this series of midface ORN requiring FF reconstruction preoperative nutritional status impacted postoperative complications. Preoperative occurrence of a fistula, pathologic fracture, and intraoral bone exposure correlated with decreased tolerance of a regular diet following reconstruction.

RESUMEN

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.

RESUMEN

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.

RESUMEN

BACKGROUND: Massive oropharyngeal bleeding post-chemoradiotherapy is a life-threatening condition that requires emergent management. METHODS: This retrospective case series included 11 patients with oropharyngeal squamous cell carcinoma who suffered from massive bleeding during or following treatment with definitive chemoradiotherapy. Details of acute and definitive management of oropharyngeal bleeding are reported. RESULTS: Nine of 11 hemorrhagic events occurred a mean (SD) of 88.6 days (53.6) after radiotherapy. Airway intubation and embolization were performed in 10 of 11 patients, followed by surgery in 7 of 11 patients. The most commonly embolized vessels were the external carotid and lingual arteries. At the time of discharge, 3 of 11 patients had a tracheostomy, and 7 of 11 continued to use a gastrostomy tube. Four patients died. CONCLUSIONS: Hemorrhagic complications in oropharyngeal cancer treatment require emergent responses. Developing a workflow for coordination between multidisciplinary teams can maximize probability of survival and decrease morbidity.

RESUMEN

OBJECTIVE: To identify practices in microvascular techniques in routine and challenging scenarios. STUDY DESIGN: Cross-sectional study. METHODS: A national survey addressing practices related to microvascular free flap reconstruction was distributed to AHNS members between October and November 2021. RESULTS: The respondents encompassed 95 microvascular surgeons. Median years of practice was 6 (interquartile range, 2-13) and median flaps per year was 35 (22-50). Common practices in arterial anastomosis included limited cleaning of artery (84.2%), use of a double approximating clamp (64.2%), and use of interrupted suture (88.4%). Common practices in venous anastomosis included limited cleaning (89.5%), downsizing the coupler (53.7%), and coupling to two independent venous systems (47.4%). In arterial anastomosis, respondents felt that kinking (50.5%) and tension (24.2%) were the riskiest challenges. Kinking was handled by loose sutures or native tissue/dissolvable biomaterial to orient pedicle. Excess tension was handled by additional dissection. With regards to associated practices, most surgeons perform anastomosis after partial inset (52.6%), give aspirin immediately postoperatively (66.3%), reserve transfusion for hemodynamic instability (69.5%), and utilize intraoperative pressors when needed (72.6%). More senior surgeons reported placing more suture to address leaks (p = 0.004) and perform end to side anastomosis on larger vein in case of venous mismatch (p = 0.012). In cases of tension, higher volume surgeons perform more extensive dissection (p = 0.035) and end to side coupling (p = 0.029). CONCLUSIONS: This survey of AHNS members indicates patterns of microvascular techniques in routine and challenging scenarios. There exists a variation in approaches amongst surgeons based on volume and practice length. LEVEL OF EVIDENCE: 5 Laryngoscope, 134:1265-1277, 2024.

RESUMEN

Background: The objective outcomes of masseteric nerve transfer in the setting of parotid malignancy are unclear. Objective: To measure objective facial reanimation outcomes of masseteric nerve transfer in patients with parotid malignancy who underwent parotidectomy with facial nerve resection. Materials and Methods: Retrospective review of patients who underwent masseteric nerve transfer for facial paralysis secondary to parotid malignancy was carried out at a tertiary referral hospital from August 2017 to November 2021. Objective facial reanimation outcomes were analyzed using Emotrics. Minimal follow-up of 6 months was required for inclusion. Results: Eight patients (five males) with a median age of 75.5 years (range 53-91) met inclusion criteria. Fifty percent had metastatic squamous cell carcinoma, and 50% had primary parotid malignancy. Five patients underwent concomitant cancer resection with facial nerve reconstruction. Seven patients received postoperative adjuvant radiotherapy. After reinnervation, patients had improved oral commissure excursion (from 1.51 mm ±1.27 to 3.77 mm ±1.81; p < 0.01) and facial symmetry during smile. Conclusion: In this study, masseteric nerve transfer enhanced oral commissure excursion and facial symmetry during smile in patients with parotid malignancy and facial nerve resection.

RESUMEN

OBJECTIVE: To assess if there is increased risk of free flap failure in renal failure patients undergoing head and neck reconstruction. We seek to primarily assess free flap outcomes based on stages of chronic kidney disease (CKD) and secondarily determine increased risk for postoperative complications. METHODS: Retrospective chart review was performed at five tertiary care centers. Patients were identified that had undergone microvascular free flap reconstruction of the head and neck with diagnosis of renal failure, classified as Stage 3 CKD or higher. Demographic data was collected. Outcomes in the postoperative period were examined. RESULTS: Seventy-three patients met inclusion criteria. The average patient age was 69 years with a male predominance (n = 48). The majority of patients had CKD Stage 3 (n = 52). Overall flap failure rate was 12.33% (n = 9, CKD stage 3 = 7.69%, CKD stage 4 = 30%, CKD stage 5 = 18%). There was an increased risk of flap failure on multivariate analysis for CKD stage 4/5 patients when compared to CKD 3 patients (p = 0.0095). When compared to matched controls, there was an increased risk of flap failure in CKD patients (p = 0.01) as well as an increased risk of overall complications (p < 0.0001). CONCLUSIONS: Patients with CKD undergoing head and neck reconstruction are at a higher risk of flap failure and overall complications. When comparing CKD stages there may be increased risk of flap failure in later stages of CKD compared to CKD 3. Appropriate patient counseling is recommended pre-operatively in this patient population with consideration for regional flaps in the appropriate patient.

RESUMEN

OBJECTIVE: The aim of the study was to determine outcomes after interventional radiology treatment of carotid blowout. METHODS: Patients with head and neck cancer and who received interventional radiology treatment for carotid blowout between 2000 and 2022 were included. Pre-treatment, treatment, and post-treatment variables were evaluated. RESULTS: Fourteen patients met inclusion criteria. Eleven patients (78.6%) had a history of radiation. Twelve (85.7%) blowouts occurred within 6 months of recent intervention. Initial treatment was with stenting (n = 9, 64.3%), coil embolization (n = 4, 28.6%), or both (n = 1, 7.1%). Six patients (42.9%) underwent subsequent carotid bypass. Morbidity following treatment included stroke (n = 1) and rebleeding (n = 4). Six-month survival was 57.1%. Of the patients who survived past six months, 5/8 were treated with carotid bypass and coverage. Four patients died of cancer progression, three of rebleeding, and three of medical complications. CONCLUSION: The majority of carotid blowout occurs within 6 months of surgery or radiation. Many who survive will die of cancer progression or medical illness. Carotid bypass with flap coverage may be a worthwhile treatment for carotid blowout and should be considered as an adjunct to endovascular treatment.

RESUMEN

OBJECTIVE: To evaluate the effect of different virtual reality (VR) experiences on perioperative anxiety and pain among patients undergoing head and neck surgery. METHODS: Prospective, randomized, comparative trial among patients undergoing outpatient head and neck surgery from December 2021 to April 2022 at a single academic institution. Group 1 utilized a preoperative VR gaming experience and a postoperative VR mindfulness experience, while Group 2 utilized the same interventions in the reverse order. Anxiety and pain were measured using visual analog scales (VAS). Primary outcomes were changes in post-intervention anxiety and pain. Secondary outcomes included vital sign changes and subjective patient experiences using a 5-point Likert scale. RESULTS: There were 32 patients randomized for inclusion, with 16 patients per group. The majority of patients were female (65.6%) and mean (standard deviation) age was 47.3 (16.7) years. After outlier exclusion, there were no differences in post-intervention preoperative anxiety reduction (Group 1 vs. Group 2, median [IQR]: -12.0 [15] vs. -10.5 [13], p = 0.62). There were minor differences in vital sign changes (p < 0.05). Among the 10 patients in Group 1 and 12 patients in Group 2 who completed postoperative VR use, there were no differences in post-intervention pain reduction (-8.5 [22.3] vs. -7.5 [19.3], p = 0.95) or vital sign changes (p > 0.05). There were no differences in questionnaire responses, with high satisfaction in both groups (p > 0.05). No adverse events encountered. CONCLUSIONS: Use of different VR experiences among patients undergoing outpatient head and neck surgery appears associated with similar reductions in perioperative anxiety and pain.

RESUMEN

OBJECTIVES: Microvascular free tissue transfer is routinely used for reconstructing midface defects in patients with malignancy, however, studies regarding reconstructive outcomes in invasive fungal sinusitis (IFS) are lacking. We aim to describe outcomes of free flap reconstruction for IFS defects, determine the optimal time to perform reconstruction, and if anti-fungal medications or other risk factors of an immunocompromised patient population affect reconstructive outcomes. METHODS: Retrospective review of reconstruction for IFS (2010-2022). Age, BMI, hemoglobin A1c, number of surgical debridements, and interval from the last debridement to reconstruction were compared between patients with delayed wound healing versus those without. Predictor variables for delayed wound healing and the effect of time on free flap reconstruction were analyzed. RESULTS: Twenty-seven patients underwent free flap reconstruction for IFS. Three patients were immunocompromised from leukemia and 21 had diabetes mellitus (DM). Patients underwent an average of four surgical debridements for treatment of IFS. The interval from the last IFS debridement to flap reconstruction was 5.58 months (±5.5). Seven flaps (25.9%) had delayed wound healing. A shorter interval of less than 2 months between the last debridement for IFS and reconstructive free flap procedure was associated with delayed wound healing (Fisher Exact Test p = 0.0062). Other factors including DM, BMI, HgA1c, and bone reconstruction were not associated with delayed wound healing. CONCLUSION: Patients with maxillectomy defects from IFS can undergo microvascular-free flap reconstruction with good outcomes while on anti-fungal medication. Early reconstruction in the first 2 months after the last IFS debridement is associated with delayed wound healing. LEVEL OF EVIDENCE: 4 Laryngoscope, 134:1642-1647, 2024.

RESUMEN

INTRODUCTION: Coronavirus disease 2019 (COVID-19) affects the vascular system, subjecting patients to a hypercoagulable state. This is of particular concern for the success of microvascular free flap reconstruction. This study aims to report head and neck free flap complications in patients with COVID-19 during the perioperative period. We believe these patients are more likely to experience flap complications given the hypercoagulable state. METHODS: This is a multi-institutional retrospective case series of patients infected with COVID-19 during the perioperative period for head and neck free flap reconstruction from March 2020 to January 2022. RESULTS: Data was collected on 40 patients from 14 institutions. Twenty-one patients (52.5%) had a positive COVID-19 test within 10 days before surgery and 7 days after surgery. The remaining patients had a positive test earlier than 10 days before surgery. A positive test caused a delay in surgery for 16 patients (40.0%) with an average delay of 44.7 days (9-198 days). Two free flap complications (5.0%) occurred with no free flap deaths. Four patients (10.0%) had surgical complications and 10 patients had medical complications (25.0%). Five patients (12.5%) suffered from postoperative COVID-19 pneumonia. Three deaths were COVID-19-related and one from cancer recurrence during the study period. CONCLUSION: Despite the heightened risk of coagulopathy in COVID-19 patients, head and neck free flap reconstructions in patients with COVID-19 are not at higher risk for free flap complications. However, these patients are at increased risk of medical complications. LEVEL OF EVIDENCE: 4 Laryngoscope, 2023.

RESUMEN

The palatal island rotation flap is a rarely used reconstructive technique. The tissue is robust and the morbidity is low. It can be used as a primary reconstructive technique in patients with limited oral cavity/pharynx lesions. Healing is uneventful. In radiated pateints healing is prolonged and should be avoided. We describe 14 patients where the flap was used to reconstruct local defects. Patients with no history of radiation all healed quickly and well. Those with a history of radiatiuon had prolonged pain and delayed healing. Laryngoscope, 2023.

RESUMEN

The implantable arterial doppler (IAD) is frequently used to postoperatively monitor free flaps with high accuracy, but there are no guidelines for its use. Bedside exam is used adjunctively to determine necessary intervention. This systematic review seeks to discover why the doppler is used adjunctively despite its established record of accuracy. Criteria for inclusion and exclusion were established. In total, 280 articles were found on PubMed and Web of Science, then screened accordingly. Data from 22 articles were analyzed using a bivariate hierarchical random effects model. Twenty-two studies yielded 2996 total patients undergoing 3127 free flap procedures. The meta-analysis found a high sensitivity of 0.809 (95% CI = 0.709, 0.880) and specificity of 0.966 (95% CI = 0.947, 0.979). False-positive rate was found to be 0.034 (95% CI = 0.021, 0.053). Positive and negative predictive values were 0.711 (95% CI = 0.581, 0.817) and 0.979 (95% CI = 0.966, 0.988). Positive and negative likelihood ratios were 24.7 (95% CI = 14.5, 39.5) and 0.20 (95% CI = 0.12, 0.30). The established efficacy of the IAD is supported by this study. Clinical exams may remain as the final adjunct due to the risks of inaccurate IAD signals. Further studies are warranted to optimize its use for future practice guidelines.

RESUMEN

OBJECTIVES: Iatrogenic injury of the fibula free flap pedicle is rare. Postoperative flap survival and reconstructive outcomes following intraoperative pedicle severance are unknown. This study assesses free flap outcomes following accidental severance of the peroneal vessels. METHODS: Multi-institutional retrospective chart review from 2000 to 2020. RESULTS: Of 2975 harvested fibula free flaps, 26 had a history of pedicle severance during surgical reconstruction. Reasons for intraoperative pedicle severance included transection during muscular dissection 10/26 (39%), accidental severance with the bone saw 12/26 (46%), and other 4/26 (15.6%). The surgeon responsible for pedicle severance included residents 5/26 (19%), fellows 10/26 (39%), attendings 10/26 (39%), and unknown 1/26 (3.9%). The pedicle artery and vein were severed 10/26 (39%), artery 8/26 (31%), and vein 8/26 (31%). Truncated pedicle vessels were used 3/26 (11.7%), intraoperative anastomoses were performed 23/26 (89%). Postoperative revision in the OR within 7 days of surgery was required 6/26 (23%); 4 flaps were salvaged and 2 flaps failed, both arterial thrombosis. Flap failure was attributed to vascular thrombosis. Long-term flap survival and successful reconstructions were reported 24/26 (92%). CONCLUSION: Accidental severance of fibula free flap pedicle vessels can be corrected with intraoperative repair, without affecting long-term flap survival or reconstructive outcomes. Protecting the flap vessels while using the bone saw and during intramuscular dissection prevents accidental severance.

RESUMEN

OBJECTIVE: To determine whether gender differences exist in the training history, practice patterns, and home lives of surgeons who perform microvascular reconstruction of the head and neck. STUDY DESIGN: Cross-sectional survey. SETTING: Medical facilities that employ surgeons who practice head and neck microvascular reconstruction in the United States. METHODS: A survey was created using the Research Electronic Data Capture Framework and was distributed via email to microvascular reconstructive surgeons. Descriptive statistics were performed using Stata software. RESULTS: No significant differences were found in training or current practice patterns between microvascular surgeons who identify as men versus those who identify as women. Women had fewer children (p = .020) and were more likely to be childless (p = .002). Whereas men were more likely to report a spouse/partner as primary caretaker, women were more likely to hire a professional caretaker or cite themselves as a primary caretaker (p < .001). Women were more likely to have finished residency (p = .015) and fellowship (p = .014) more recently and to practice in the Southeast (p = .006). Of the microvascular surgeons who reported practice setting switches, men more commonly changed positions for career advancement, whereas women were more likely to switch due to burnout (p = .002). CONCLUSION: This study found no gender-based differences in training or practice patterns. However, significant differences were identified in childbearing, family structure, geographic practice location, and motives for switching practice.

RESUMEN

BACKGROUND: There are variations in implantable arterial Doppler usage for microvascular free tissue monitoring among North American surgeons. Identifying utilization trends among the microvascular community may elucidate practice patterns that may be useful in determining protocols. Furthermore, study of this information may yield novel and unique applications in other disciplines such as vascular surgery. METHODS: Electronically disseminated survey study shared with a large database of North American head and neck microsurgeons. RESULTS: Seventy four percent of respondents use the implantable arterial Doppler; 69% report use in all cases. Ninety five percent remove the Doppler by the seventh postoperative day. All respondents felt that the Doppler did not impede care progression. Any implication of flap compromise was followed with a clinical assessment in 100% of respondents. If viable, 89% would continue monitoring after clinical examination, while 11% would take the patient for exploration regardless of clinical examination. CONCLUSIONS: The efficacy of the implantable arterial Doppler has been established in the literature and is supported by the results of this study. Further investigation is required to establish a consensus on use guidelines. The implantable Doppler is more often used in conjunction with rather than substitution for clinical examination.

RESUMEN

BACKGROUND: Complex scalp wounds with cranial/dural involvement are challenging to reconstruct. Successful reconstruction can be achieved with cranial implants/hardware and free flap coverage. Wounds can breakdown and require revision procedures. We addressed reconstructive outcomes of different implants requiring free flaps. OBJECTIVE: To determine the factors associated with implant exposure. DESIGN: Multi-institutional retrospective review of 82 patients, 2000-2020, repaired with cranial implants and free flap coverage. RESULTS: Implant exposure occurred in 13/82 (16%) reconstructions. Flap atrophy or thinning leading to implant exposure occurred in 11/82 (13%) reconstructions, including partial flap atrophy OR 0.05 (95% CI 0.0-0.35) and total flap atrophy OR 0.34 (95% CI 0.02-19.66). Revision surgeries that occurred subsequent to flap reconstruction were also associated with implant exposure (OR 0.02 (95% CI 0.0-0.19)). Implant exposure was not associated with radiation therapy, patient health history, implant type, flap type, or postoperative complications. CONCLUSIONS: Implant exposure is associated with free flap atrophy, leading to inadequate implant coverage and the need for revision surgeries. Completing reconstruction with adequate soft tissue bulk and coverage and avoiding revision surgery may decrease the risk for implant exposure over time.

RESUMEN

OBJECTIVES: The rectus abdominis myocutaneous free flap has been widely used as a reconstructive option in head and neck reconstruction with great success. Challenging the popular assumption, this study sought to examine the effects of smoking on donor site complications in this population. METHODS: Multi-institution retrospective study of 103 patients (50 active smokers, 28 former and 25 never smoked). RESULTS: Overall complication rate was 14.5 %. Hernia rate 4.8 %, evisceration 0 %, dehiscence 2.9 %, infection 6.7 %. Smoking history did not significantlly influence complication rates (chi square test, p = 0.33). Abdominal wall closure technique also did not influence the complication rate (chi square test, p = 0.58). CONCLUSIONS: The rectus abdomonis myocutaneous free flap has an acceptable complication rate that does not appear to be influenced by smoking history. While patients should be counseled regarding smoking cessation, smoking habits should not delay treatment nor obviate consideration of rectus flap utilization.

RESUMEN

BACKGROUND: The utilization of an arteriovenous loop is an underreported technique that affords the creation of reliable vascular options. Understanding the efficacy and impacting variables of microvascular reconstruction with an arteriovenous loop can be critical to its use. METHODS: Multi-institutional study of 36 patients who underwent vein grafting or AV loop with free tissue transfer. RESULTS: 58.3% of patients received prior radiation and 38.9% prior flap reconstruction. Flap success for vein grafting was 76% and AV loop was 100% (p = 0.16). Success for the radiated cohort was 90.5% and non-radiated 80% (p = 0.63). Flap success for the radiated, vein grafted patient was 83.3% and 100% flap success rate for radiated, AV loop patient (p = 0.49). Overall flap survival was 83.3% versus 97% overall success rate in the United States. CONCLUSION: The AV loop is a viable modality for vessel-depleted free tissue reconstruction. Radiation and previous surgery do not significantly impact flap success rates.
