Background: A major prognostic indicator in patients with squamous cell carcinoma of the upper aerodigestive tract is the presence or absence of cervical metastasis. Nodal involvement at different levels affects treatment. Thus identification of the degree of nodal involvement is important. Evaluation of the neck by conventional imaging modalities (computed tomography or magnetic resonance imaging) is not completely accurate. Positron emission tomography (PET) scanning as a dynamic functional assessment may allow detection of multiple metastatic nodes at different levels. Purpose: We sought to compare the effectiveness of PET with pathologic examination for: presence, location, and number of cervical metastases in the clinically N-positive neck. Setting: Tertiary care academic facility. Materials and methods From 1994 to 1997, 15 patients with clinically N-positive necks who had preoperative PET scans underwent 23 neck dissections. PET scans were correlated with the pathologic findings of the neck dissections in determining the ability to correctly identify the number and level(s) of nodal disease. Results: When determining identification of the level of disease, PET demonstrated sensitivity of 81%; specificity, 99%; positive predictive value, 97%; negative predictive value, 90%; and accuracy, 92%. When evaluating the ability to correctly predict neck stage, PET demonstrated sensitivity of 86%, positive predictive value of 100%, and accuracy of 80% compared with clinical examination with sensitivity of 53% and accuracy of 53%. Conclusion: PET accurately identified disease in the N-positive neck. Its ability to identify multiple level disease may allow it to help predict the selectivity of neck dissection in the therapeutic protocol. [ABSTRACT FROM AUTHOR]

Objective: Photodynamic therapy (PDT) may be used as an adjuvant intraoperative treatment to improve locoregional control. PDT has been shown both to delay wound healing and to have a deleterious effect on flap survival after a primary ischemic insult. This delay in wound healing may make the flap dependent on its pedicled blood supply for a prolonged period. Long-term flap loss may be experienced. The effect of PDT on flap revascularization, with subsequent dependence on its vascular pedicle, is evaluated. Study Design: Randomized controlled trial using a rodent model. Methods: A rat fasciocutaneous flap was used. Study groups were as follows: group I received no treatment; group II received treatment with 630-nm light; groups IH and IV were given Photofrin (in group III, loupes without a fiberoptic light source were used for flap elevation, and in group IV, light source was employed); and group V was given Photofrin and 630-nm light. Primary ischemic times of 2 or 4 hours were used. Vascular pedicles were ligated on postoperative day (POD) 5, 6, or 7, and percentage of flap survival was evaluated 7 days later. Results: With 2 hours of ischemia, revascularization was decreased in the PDT group on POD 6 (P < .05) and on day 7 (P < .005) when compared with the other groups. With 4 hours of ischemia, revascularization was decreased in the PDT group on PODs 5 (P < .001), 6 (P < .01), and 7 (P < .005). Conclusion: Intraoperative PDT decreases revascularization of a rat fasciocutaneous flap. [ABSTRACT FROM AUTHOR]

Objective: To study the physiologic effect of acute thyroid hormone depletion on hearing and the function of outer hair cells.Design: Audiologic and otoacoustic emission testing of subjects undergoing total thyroidectomy before surgery and up to 6 weeks after surgery. Magnitude of thyroxin depletion monitored by serum thyroid-stimulating hormone levels.Setting: Hearing research laboratory at a state university.Subjects: Ten patients undergoing total thyroidectomy.Main Outcome Measures: Detection of hearing loss on audiogram and decrease or disappearance of otoacoustic emissions as a result of acute thyroxin depletion.Results: No significant changes in the audiogram and otoacoustic emission configurations were detected, although thyroid-stimulating hormone levels became elevated after total thyroidectomy.Conclusion: Although thyroid hormone is thought to play a role in the physiology of hearing in humans, no deleterious effects on hearing can be identified up to 6 weeks after thyroxin depletion.

Background: Radiotherapy is effective treatment for laryngeal carcinoma. Early-stage laryngeal carcinoma has a low incidence of cervical metastasis. Patients initially clinically N0 usually remain N0 when they fail at the primary site. The incidence of subclinical metastasis in these patients is not well described. Watchful waiting or elective neck dissections are advocated.Objective: Examine the incidence of subclinical metastatic disease in patients undergoing elective neck dissections with salvage laryngectomy.Study Design: Prospective study (1991-1996) of patients who failed radiotherapy and underwent salvage laryngectomy with elective neck dissection.Methods: Thirty-four patients underwent salvage laryngectomy with neck dissection (30 bilateral, 4 unilateral). All were clinically N0 at initial presentation and remained N0 at recurrence. Pathologic study of the neck dissection specimens was undertaken. Patients were followed for a minimum of 2 years (mean, 4 y).Results: The male-to-female ratio was 4.5:1, with a mean age of 62 years (range, 38 to 75 y). Metastatic disease was present in 6 patients (17%); 4 of 14 (28%) supraglottic, and 2 of 20 (10%) glottic. Presence of disease in the neck according to stage at recurrence was as follows: T2, 2 of 12; T3, 3 of 14; and T4, 2 of 8. Neck disease was ipsilateral in 4 and contralateral in 2 patients (both supraglottic primaries).Conclusions: Subclinical cervical metastasis may be present in N0 laryngeal carcinoma patients who have recurrence following radiotherapy. Morbidity of a lateral neck dissection is minimal, with excellent control of the neck being possible. Supraglottic and advanced glottic (T3-T4) patients may benefit the most. [ABSTRACT FROM AUTHOR]

Objectives/hypothesis: Vocal rehabilitation of patients who have undergone laryngectomy is best accomplished by a tracheoesophageal puncture. Optimal function of the prosthesis requires an adequate stoma. Patients with tracheostomal stenosis require revision of the stoma if vocal rehabilitation is to take place. Revision and tracheoesophageal placement are usually done as two separate procedures. Creating a tracheoesophageal fistula at the time of stomal revision has not been addressed in the literature.Study Design: Prospective analysis and follow-up of 10 patients undergoing simultaneous tracheoesophageal puncture and stomal revision for tracheostomal stenosis between 1991 and 1996.Methods: Ten patients were reviewed. An inferiorly based V-Y advancement flap was used so as not to interfere with the tracheoesophageal puncture. All patients had received radiation prior to revision and tracheoesophageal puncture. Patients were followed for a minimum of 2 years (range, 2-6 y; median, 3 y).Results: All patients maintained an adequate stoma without stenting. Eight of ten patients (80%) developed and maintained good tracheoesophageal speech. Two patients had their speech fistulas removed. There were no intraoperative or postoperative complications.Conclusions: Creation of a tracheoesophageal fistula at the time of stomal revision allows for vocal rehabilitation with a single visit to the operating room.

Objectives/hypothesis: Normal salivary flow is important for maintaining good oral hygiene. Lack of normal flow predisposes to an increased incidence of dental caries and symptomatic xerostomia. The submandibular glands are responsible for 70% of resting salivary flow. Removal of the submandibular gland is most commonly performed for sialolithiasis, chronic sialoadenitis, or as part of a neck dissection. The effect of unilateral gland resection for benign disease on resting salivary flow has not been well examined in the literature.Study Design: Case controlled study involving patients who had undergone a unilateral submandibular gland resection matched with normal control subjects.Method: Stimulated and unstimulated salivary flow rates in surgical and control subjects were measured in a controlled setting.Results: Unstimulated salivary flow rates were 0.805 mL/min in the control group and 0.405 mL/min in the surgical group (P = .01). Stimulated salivary flow rates were not significantly different between the two groups (P > .05). Fifty-seven percent of patients in the surgical group and 14% in the control group had xerostomia (P < .05).Conclusion: Unilateral submandibular gland excision results in a decreased rate of resting salivary flow and an increase in subjective xerostomia.

The presence of cervical lymph node metastasis in patients with head and neck cancer is associated with an unfavorable prognosis. Reports vary as to whether various conventional radiographic studies, such as computed tomography (CT) and magnetic resonance imaging, confer an advantage over physical examination in the patient without clinical findings of cervical metastasis (N0). Positron emission tomography (PET) is a functional imaging modality that has recently been used for head and neck neoplasms. The use of PET in the evaluation of the N0-staged neck in 14 consecutive patients with squamous cell carcinoma (SCC) of the upper aerodigestive tract is reported. Seven patients (50%) undergoing 13 neck dissections had pathologic evidence of disease. PET scans were positive in five patients with pathologically confirmed cervical metastasis. PET scans were negative in seven patients (11 neck dissections) with no pathologic evidence of disease. PET scans were positive for unilateral cervical metastasis in two of three patients with involvement of a single lymph node. PET scans were positive in two of three patients with more than two lymph nodes involved. PET had an accuracy of 100% in the eight patients with SCC of the oral cavity. In patients with oropharyngeal or hypopharyngeal carcinoma PET localized cervical metastasis in two of four patients with neck metastasis. In the patient with an N0-staged neck on clinical examination, PET was found to have an overall sensitivity of 78%, specificity of 100%, positive predictive value of 100%, negative predictive value of 88%, and accuracy of 92%. CT demonstrated sensitivity of 57%, specificity of 90%, positive predictive value of 80%, negative predictive value of 75%, and accuracy of 76%. PET showed a trend in increased accuracy (P = 0.11) over CT. PET appears to be a promising diagnostic aid that may be applied when evaluating the N0-staged neck, especially for SCC of the oral cavity. [ABSTRACT FROM AUTHOR]

Atelectasis is the most common postoperative complication encountered in head and neck surgery. Risk factors include preexisting pulmonary disease, type of surgery performed, and the length of anesthetic. It is controversial whether reconstruction of defects with regional myogenous flaps predisposes to atelectasis. The latissimus dorsi myocutaneous flap requires the patient to be placed on his side for a period of time. Whether it is the position or the surgery that contributes to the development of atelectasis has not been examined. Eighteen patients underwent latissimus dorsi myocutaneous flap reconstruction following major ablative procedures for head and neck cancer. The cutaneous area transferred ranged from 70 to 225 cm2 (mean, 128 cm2). The flap size ranged from 7 x 10 to 15 x 15 cm. The majority of flaps were 10 x 15 cm or greater. These patients were compared to 18 patients who did not undergo pedicled myocutaneous chest flap reconstruction. Patients were matched for age, sex, length of operation, site of primary, and stage of disease. Postoperative atelectasis was radiographically detected in 89% of flap patients vs. 79% of controls. Major atelectasis was encountered in 16% of patients undergoing flap surgery vs. 11% of patients in the control group. Patients with large cutaneous paddles on the flaps (> 120 cm2) had significantly more atelectasis than patients with smaller cutaneous paddles (P<.05, chi-squared). The incidence of radiographic postoperative atelectasis in patients having a latissimus dorsi myocutaneous flap is high. The size of the skin paddle harvested as well as the position change may contribute to this. [ABSTRACT FROM AUTHOR]

Background: Vessel grafting is an important technique in head and neck free tissue transfer (FTT) reconstruction when a tension-free anastomosis is not otherwise feasible. To our knowledge, there are limited data regarding interposition artery grafts for arterial anastomoses in head and neck reconstruction. Here, we present a multi-institutional cohort of arterial interposition grafts for FTT reconstruction for head and neck defects., Methods: A retrospective review was conducted at four tertiary care institutions for patients who underwent FTT reconstruction for head and neck defects which utilized an interposition artery graft for the arterial anastomosis. Charts were reviewed for type and length of artery grafts harvested, surgical indication, indication for artery graft, types of flaps harvested, and various preoperative characteristics (including history of radiation or previous FTT reconstruction surgery). Postoperative complications within postoperative day 30 were measured and reported., Results: Nine patients met inclusion criteria. The lateral circumflex femoral artery (either transverse or descending branches) (n = 3) and facial artery (n = 3) were the most commonly harvested arteries. The scalp (n = 5) was the most common primary defect site. Seven grafts were harvested initially and in a planned fashion, while two were harvested as salvage techniques (either for flap salvage or vein graft failure). In planned grafts, arteries were the preferred interposition grafting method due to either size match preferences (n = 4) or similarities in wall thickness (n = 3) between graft and recipient artery. There were no reported cases of unplanned readmission, postoperative hematoma, fistula formation, wound infection, or donor site morbidities. Two patients required unplanned return to the operating room for flap compromise, both of which ultimately resulted in flap failure secondary to clot formation at both arterial and venous anastomoses., Conclusions: When arterial pedicle length is insufficient, interposition artery grafting is both a feasible and viable technique to achieve tension-free arterial anastomoses for select cases of highly complex head and neck free tissue reconstruction., (© 2024 Wiley Periodicals LLC.)

Key Points: Virtual reality (VR) and Fitbit devices are well tolerated by patients after skull base surgery. Postoperative recovery protocols may benefit from incorporation of these devices.

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., (© 2024 The Authors.

Objective: Assess the long-term plate complications with patient-specific plates (PSPs) created with computer-aided design (CAD) and computer-aided manufacturing (CAM) for fibula free flap reconstructions for mandibular defects., Methods: Retrospective chart review from January 2010 to July 2022 of patients who underwent mandibular reconstruction with a fibula free flap and PSP. Primary outcome was plating-related complications, defined as plate exposure, fracture, loose screws, and plate removal., Results: A total of 221 patients underwent PSP fibula reconstruction. Average age was 59.8 + 14.3 years old with male to female ratio of 2:1. Squamous cell carcinoma of the mandible was the most common reason for resection, 47.5%, n = 105. Plate removal occurred in 11% of patients (n = 25) about 17.4 months after the initial surgery. Plates were removed due to exposure (76%, n = 19) or screw loosening (24%, n = 6). Malignancy was associated with an increased risk of plate complications when compared to benign tumor (odds ratio [OR] 9.04, confidence interval [CI] 1.36-3.85), osteonecrosis (OR 1.38, CI 0.59-3.48), and trauma (OR 1.26, CI 0.23-12.8). Postoperative radiation therapy (OR 2.27, CI 1.07-4.82, p = 0.026) and surgical site infection (OR 9.22, CI 4.11-21.88, p = 0.001) were associated with more plate complications., Conclusions: CAD creates PSPs that remain stable in the majority of patients over the long term. Plate removal is less compared to non-PSP reconstruction. Consideration of the soft tissue envelope over the plate and management of perioperative infection at the time of surgery should be entertained., Level of Evidence: Level 4 Laryngoscope, 2024., (© 2024 The American Laryngological, Rhinological and Otological Society, Inc.)

Introduction: Cervical spine defects result in spinal instability, putting the spinal cord and vertebral arteries at risk of damage and possibly devastating neurological injuries. The fibula free flap can span the spinal defects for stability. There is a paucity of literature on this technique., Method: Multi-institutional retrospective case series reviewing patients who underwent cervical spine reconstruction with a fibula free flap. Patient demographic information, comorbidities, characteristics of cervical spine defects, and free flap complications were collected., Results: A total of 1187 fibula free flaps across 10 different institutions were reviewed. Thirteen patients (1.09%) underwent cervical spine reconstruction with a fibula free flap. Average age was 52.3 years old with an age range of 12-79 years. There were six males (46.1%) and seven females (53.8%). The most common defect etiology was infection (n = 6, 46.1%). Most commonly involved cervical spine level of the defect was C5 (n = 10) followed by C6 (n = 9) and C4 (n = 8). The majority of reconstructed defects spanned three or more cervical levels, (n = 9, 69.2%). Facial artery was the most common arterial anastomosis (n = 8). Eight patients (61.5%) required a tracheostomy during their postoperative course. None of the patients had symptomatic or radiographic nonunion., Conclusion: This case series demonstrates that a vascularized fibula flap is a potential reconstructive option for cervical spine defects, especially in defects greater than three cervical levels, in the setting of infection, and previously radiated patients., Level of Evidence: Level 4 Laryngoscope, 2024., (© 2024 The American Laryngological, Rhinological and Otological Society, Inc.)

Background: Free flap (FF) reconstruction of traumatic injuries to the head and neck is uncommon., Methods: Multi-institutional retrospective case series of patients undergoing FF reconstruction for a traumatic injury (n = 103)., Results: Majority were gunshot wounds (GSW; 85%, n = 88) and motor vehicle accidents (11%, n = 11). Majority underwent osseous reconstruction (82%, n = 84). FF failures (9%, n = 9/103) occurred in GSW patients (100%, n = 9/9) and when multiple subsites were injured (89%, n = 8/9). Preoperative antibiotics correlated with lower rates of a neck washouts (4% vs. 19%) (p = 0.01) and 30-day readmissions (4% vs. 17%) (p = 0.02)., Conclusions: All FF failures occurred in the setting of a GSW and the majority involved multiple subsites. Preoperative antibiotics correlated with lower rates of postoperative washout procedures and 30-day readmission., (© 2024 The Author(s). Head & Neck published by Wiley Periodicals LLC.)

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., (© 2024 The Author(s).

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, 134:2718-2720, 2024., (© 2023 The American Laryngological, Rhinological and Otological Society, Inc.)

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: 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., (© 2024 Wiley Periodicals LLC.)

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., (© 2023 The American Laryngological, Rhinological and Otological Society, Inc.)

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.

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., Level of Evidence: 2 Laryngoscope, 134:1197-1202, 2024., (© 2023 The American Laryngological, Rhinological and Otological Society, Inc.)

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., Level of Evidence: 4 Laryngoscope, 134:695-700, 2024., (© 2023 The American Laryngological, Rhinological and Otological Society, Inc.)

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., (© 2023 The Authors.

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., (Copyright © 2023 Elsevier Inc. All rights reserved.)

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., (© 2023 American Academy of Otolaryngology-Head and Neck Surgery Foundation.)

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., Level of Evidence: 4 Laryngoscope, 133:2954-2958, 2023., (© 2023 The American Laryngological, Rhinological and Otological Society, Inc.)

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., (© 2023 The Authors.

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., (© 2023 Wiley Periodicals LLC.)
