RESUMO
Nasal reconstruction presents the facial plastic surgeon with a complex problem given its functional and aesthetic importance. The dorsal nasal flap is a composite rotation flap of the glabella and nasal dorsum that can be used for nasal dorsum and tip defects of medium-to-large sizes. Given its composite nature, this flap can be split into its constituent parts-the epidermis and dermis and the subcutaneous tissue and superficial musculoaponeurotic system-without flap loss. This case series describes this technique and various potential applications within nasal reconstruction.
RESUMO
PURPOSE: To describe the presentation, diagnosis, and management of chronic otitis media recidivism after subtotal petrosectomy and ear canal closure (STP). MATERIALS AND METHODS: Patients with temporal bone pathology detected during follow-up after STP were identified in the electronic medical record. Pertinent clinical details regarding surveillance plan, presentation, imaging findings, and revision surgery were collected and analyzed. RESULTS: A total of 10 patients were identified with recurrent or persistent pathology after STP. The median time to detection was 46 months (IQR 24-84). Five patients (50 %) had non-specific symptomatology, 4 patients (40 %) were completely asymptomatic, and 1 patient (10 %) was asymptomatic outside of two instances of mastoiditis with cochlear implant device infection treated with incision and drainage. One patient (10 %) was noted to have proptosis on examination, but no other patients had objective signs of disease at detection of disease recidivism. Nine (90 %) patients had pathology identified on preoperative imaging. All patients underwent revision surgery, with identification of cholesteatoma in 8 cases (80 %) and cholesterol granuloma in 2 cases (20 %). Extensive disease was noted in 6 patients (60 %), all of whom followed-up greater than 3 years from surgery. All patients tolerated revision surgery without complication. CONCLUSIONS: Recidivistic disease often remains clinically silent for extended periods of time after STP. Planned follow-up - with imaging or second look surgery - to facilitate early detection should be considered. Undetected disease recurrence or development may result in morbidity in a proportion of patients if surveillance is not performed.

OBJECTIVE: Spontaneous otogenic pneumatocele is a rare entity resulting from a pressure gradient between a dehiscent temporal bone and the intracranial space. Secondary infection can ensue in patients with concurrent otomastoiditis. The current study discusses the clinical presentation and imaging characteristics of two cases of secondarily infected otogenic pneumatoceles. STUDY DESIGN: Case series. RESULTS: Two patients were diagnosed with a temporal lobe abscess in the setting of otogenic pneumatocele. Diagnosis was aided by both CT and MRI demonstrating a diffusion restricting lesion within brain parenchyma in association with free air in close proximity to an underlying tegmen defect. CONCLUSION: Prompt diagnosis of a secondarily infected otogenic pneumatocele with CT and MRI allows for surgical drainage with closure of the tegmen defect to prevent further complications and recurrence.

OBJECTIVE: To test the hypothesis that severe to profound preoperative hearing loss predicts less acute postoperative vestibulopathy following microsurgical removal of vestibular schwannoma (VS) allowing for earlier postoperative mobilization and hospital discharge. METHODS: Patients with VS who underwent microsurgery and were found to have preoperative severe to profound hearing loss (pure tone average [PTA]â¯>â¯70â¯dB HL) were matched 1:1 by age and tumor size to a group of randomly selected controls with preoperative serviceable hearing. RESULTS: A total of 57 patients met inclusion criteria and were matched to controls. Median age at the time of microsurgery was 56â¯years. The median PTA and WRS for cases were 91â¯dB HL (interquartile range [IQR] 78-120) and 0% (IQR 0-0), respectively. Median tumor size was 14.2â¯mm (IQR 10.9-20.9). A total of 35 (61%) patients exhibited nystagmus after surgery associated with acute vestibular deafferentation. Median time to ambulation in the hallway was 2â¯days. Controls exhibited similar tumor size (12.7â¯mm, pâ¯=â¯0.11) and age (57â¯years, pâ¯=â¯0.52). Preoperative hearing loss did not predict severity or duration of postoperative nystagmus or days to discharge; however, those with Class D hearing exhibited a shorter time to ambulation (pâ¯=â¯0.04). CONCLUSION: Following microsurgical removal of VS, preoperative profound hearing loss was associated with a shorter time to postoperative mobilization; however, there were no observed associations with duration or severity of nystagmus and time to hospital discharge. Although not a predictor of nystagmus, preoperative profound hearing loss may portend quicker recovery from clinically significant postoperative vestibulopathy.

PURPOSE: The Acoustic Neuroma Association (ANA) represents the largest existing patient support organization for those diagnosed with vestibular schwannoma (VS) in the United States. Yet, the degree to which the ANA is actually utilized across the country is unknown. Moreover, evidence suggests that there may exist significant regional variation in management practices of VS across the United States. MATERIALS AND METHODS: Patient participation in the ANA by state and geographical region, as well as their management approach, was reviewed through a cross-sectional survey performed from February 2017 through January 2019, patients diagnosed with sporadic VS. RESULTS: Among 878 patients studied, the District of Columbia had the largest proportion of ANA patients relative to state population (0.85 per 100,000 persons), followed by New Hampshire (0.74), Maine (0.60), and New Jersey (0.42). Comparatively, Mississippi (0.03), Hawaii (0.07), and Rhode Island (0.09) harbored significantly lower participation rates (p = 0.001). Significant treatment variations were observed across the United States: in Maine, Iowa, Missouri, Kansas, and New Hampshire, an average of 73% (range, 70-75) of patients underwent microsurgery, whereas only 24% (range, 0-35) of patients in Colorado, New York, Massachusetts, Connecticut, and West Virginia underwent microsurgery (p < 0.001). After controlling for patient age and tumor size, patients were significantly more likely to undergo a retrosigmoid approach than the translabyrinthine approach for medium- to large-sized tumors in the Northeast (OR = 4.18; p = 0.001) and Western United States (OR = 2.94; p = 0.009). CONCLUSIONS: Large regional variation exists surrounding patient participation in the ANA as well as management practices across the United States.

INTRODUCTION: Cochlear implantation has become an increasingly common strategy for aural rehabilitation in patients with severe to profound hearing loss who no longer benefit from conventional amplification. In conjunction, immunosuppressive therapies (e.g. disease-modifying anti rheumatic drugs (DMARDs) have become the keystone of management in numerous autoimmune conditions. Given the increasing prevalence of both, a greater proportion of patients will undergo cochlear implantation while on immune-modulating medications. While these medications are usually well tolerated, immunosuppression may put patients a higher risk for device infections. At present, this is not extensively studied within the cochlear implant literature. METHODS: We conducted a retrospective chart review and review of the literature.Results:We present the case of an 81-year-old male who experienced wound dehiscence and infection secondary to leflunomide use for treatment of rheumatoid arthritis. Resolution of these issues was noted with a therapeutic drug holiday, and the patient has subsequently undergone re-implantation without issue.Conclusions:The case highlights a potential CI-associated wound complication in the setting of DMARD therapy. Given the increasing prevalence of both CIs and immunosuppressive therapy, future study on the potential for interaction is warranted to identify the best management strategy in the perioperative setting.
RESUMO
OBJECTIVE: To describe the experience and results from coordinated and closely scheduled radiosurgery and cochlear implantation (CI) in a vestibular schwannoma (VS) cohort. PATIENTS: Patients with VS who underwent radiosurgery followed by CI on the same or next day. INTERVENTIONS: Interventions included sequential radiosurgery and CI. MAIN OUTCOME MEASURES: Tumor control defined by tumor growth on posttreatment surveillance and audiometric outcomes including consonant-nucleus-consonant words and AzBio sentences in quiet. RESULTS: In total, six patients were identified that met the inclusion criteria, with an age range of 38 to 69 years and tumor sizes ranging from 2.0 to 16.3 mm. All patients successfully underwent radiosurgery and CI on the same or immediately successive day. Postoperatively, all patients obtained open-set speech recognition. Consonant-nucleus-consonant word scores ranged from 40 to 88% correct, and AzBio scores ranged from 44 to 94% correct. During posttreatment magnetic resonance imaging surveillance, which ranged from 12 to 68 months, all tumors were noted to be adequately visualized, and no tumor progression was noted. CONCLUSION: Coordinated radiosurgery and CI can be safely performed in patients with VS on the same or next day, serving to decrease burden on patients and increase access to this vital rehabilitative strategy.

OBJECTIVE: The objective of this study was to develop a nomogram to predict long-term facial nerve (FN) function after vestibular schwannoma (VS) resection. METHODS: A retrospective cohort study of two tertiary academic skull base referral centers was performed. Consecutive adults > 18 years of age with sporadic unilateral VS who underwent resection between September 2016 and May 2021 were included. FN function in the immediate postoperative period and at the most recent evaluation was measured. RESULTS: A total of 306 patients (mean age 49 years, 63% female) were included, with a mean follow-up of 18 months. The mean maximum tumor diameter was 19 mm (range 1-50 mm), and 80 (26.1%) tumors were > 25 mm. Overall, 85% of patients showed good immediate postoperative FN function (House-Brackmann [HB] grade I or II) and 89% maintained good FN function at > 12 months of follow-up. An intraoperative FN electromyographic (EMG) response ≥ 100 µV to 0.05 mA of stimulation (OR 18.6, p < 0.001) was the strongest predictor of good HB grade in the immediate postoperative period. EMG response ≥ 100 µV (OR 5.70, p < 0.001), tumor size ≤ 25 mm (OR 3.09, p < 0.05), and better immediate postoperative HB grade (OR 1.48, p = 0.005) predicted good long-term FN function on multivariable analysis. A point-of-care nomogram based on these data predicted long-term FN function with a sensitivity of 89% and specificity of 69%. CONCLUSIONS: Better immediate postoperative HB grade, intraoperative FN EMG response ≥ 100 µV, and tumor size ≤ 25 mm strongly predicted good long-term FN function after VS resection. A point-of-care nomogram based on these variables could serve as a useful tool for postoperative counseling and prognosis of long-term FN recovery.
RESUMO
Alpha-gal syndrome (AGS) is an immunoglobulin E-mediated hypersensitivity to galatcose-alpha-1,3-galactose (alpha-gal), a carbohydrate compound present in nonprimate mammalian products. Initial exposure to alpha-gal most often occurs through a tick bite, most commonly the lone star tick in the United States. Repeated exposure to alpha-gal may elicit severe allergic reactions, including anaphylaxis. The allergy restricts dietary intake and may significantly impact perioperative risk, as many medications, anesthetics, and intraoperative surgical products utilize bovine or porcine-derived agents, including those containing magnesium stearate, glycerol, and gelatin. Here, we review the perineurosurgical care of two individuals with AGS and highlight pertinent clinical practices and perioperative management of these patients.
RESUMO
OBJECTIVE: To describe the development, implementation, and validation of a radiology-administered protocol to obtain magnetic resonance imaging (MRI) in patients with cochlear implants and auditory brainstem implants without magnet removal. STUDY DESIGN: Retrospective review and description of novel care pathway. METHODS: A radiology-administered protocol was designed based on careful input from the radiology safety committee and neurotology. Radiology technologist training modules, consent instructions, patient educational material, clinical audits, and other safeguards were implemented, with samples provided in this report. The primary outcomes measured included instances of magnet displacement during MRI and premature termination of MRI studies secondary to pain. RESULTS: Between June 19, 2018, and October 12, 2021, 301 implanted ears underwent MRI without magnet removal, including 153 devices housing diametric MRI-conditional magnets, and 148 implants with conventional axial (i.e., nondiametric) magnets. Among cases with diametric MRI-conditional magnets, all studies were completed without magnet dislodgement or need to terminate imaging early due to pain. Among cases with conventional axial (nondiametric) magnets, 29 (19.6%) MRI studies were stopped prematurely secondary to pain or discomfort; the overall rate of this event was 9.6% (29 of 301) among the entire study cohort. In addition, 6.1% (9 of 148) experienced confirmed magnet displacement despite headwrap placement; the overall rate among all cases was 3.0% (9 of 301). Eight of these patients received successful external magnet reseating through manual pressure on the external scalp without surgery, and one required surgical replacement of the magnet in the operating room. There were no documented instances of hematoma, infection, device or magnet extrusion, internal device movement (i.e., gross receiver-stimulator migration), or device malfunction in this cohort related to MRI. CONCLUSIONS: We present the successful implementation of a radiology-administered protocol designed to streamline care for cochlear implant and auditory brainstem implant recipients who require MRI and ease clinical demands for otolaryngology providers. Examples of resources developed, including a process map, radiology training modules, consent instructions, patient educational materials, clinical audit, and other procedural safety measures are provided so interested groups may consider adapting and implementing related measures according to need.

This study described the outcomes of patients receiving topical, nebulized, endobronchial, or systemic tranexamic acid (TXA) for bleeding events while on extracorporeal membrane oxygenation (ECMO). We performed a single-center case series including adult patients >18 years old supported on either venovenous (VV) or venoarterial (VA) ECMO from January 1, 2014, to April 21, 2021. The primary outcome was hemostatic control defined as a composite of initial cessation of therapeutic interventions to mitigate bleeding or resumption of anticoagulation if previously held. Secondary outcomes included changes in transfusion requirements and lysis at 30-minute (LY30) values, venous thromboembolism (VTE) events, and seizures. In total, 47 patients were included for full analysis. There were 19 patients with surgical bleeds, 18 patients with medical bleeds, and 10 patients with multiple bleeds. Overall, initial hemostatic control was achieved in 79%, 67%, and 90% of patients, respectively. Pre- and post-TXA transfusion requirements were not significantly different ( p = 0.2), although the intraindividual change in median LY30 was -5.1% compared with baseline (95% confidence interval [CI], -12.4% to -1.5%, p = 0.005). The occurrence of VTE and seizures was relatively low and similar among patient bleeding groups. Tranexamic acid provided initial hemostatic control in roughly three quarters of patients with bleeding events on ECMO and side effects were infrequent.

OBJECTIVE: To evaluate the safety and outcomes of cochlear implantation (CI) in patients with ventriculoperitoneal (VP) shunts to inform clinical practice. STUDY DESIGN: Historical cohort study. SETTING: Tertiary referral centers. METHODS: A multi-institutional historical cohort of patients with VP shunts and CI was identified and analyzed. RESULTS: A total of 46 patients (median age 8 years [interquratile range, IQR: 2-46]) with VP shunts and CI were identified. Of these, 41 (89%) patients had a VP shunt prior to CI. Based on institutional preference and individual patient factors, CI was performed contralateral to a pre-existing VP shunt in 24 of these 41 cases (59%) and ipsilateral in 17 (41%). Furthermore, pre-CI relocation of the VP shunt was performed in 3 cases (7%), and 2 patients (5%) underwent planned revision of their VP shunt concurrent with CI. In total, 2 of 27 pediatric patients (7%) required unanticipated revision shunt surgery, both contralateral to CI device placement, given VP shunt malfunction. One of 19 adult patients (5%) required shunt revision during CI due to shunt damage noted intraoperatively. Among 43 patients with available follow-up, 38 (88%) are regular CI users, with a median consonant-nucleus vowel-consonant word: score of 58% (IQR: 28-72). CONCLUSION: CI can be performed at low risk, either contralateral or ipsilateral, to a VP shunt, and does not mandate shunt revision in most cases. Additional considerations regarding CI receiver-stimulator placement are necessary with programmable shunts to mitigate device interaction. Preoperative planning, including coordination of care with neurosurgery, is important to achieving optimal outcomes.

OBJECTIVE: The objective of this study is to assess the influence of age on facial nerve recovery after microsurgical resection of sporadic vestibular schwannoma. STUDY DESIGN: A historical cohort study was performed. SETTING: The study was performed at a tertiary referral center. PATIENTS: The studied cohort included patients with a House-Brackmann (HB) Grade III or worse in the immediate postoperative period. INTERVENTIONS: The studied intervention was microsurgical resection. MAIN OUTCOME MEASURES: The main outcome measure was complete recovery of facial nerve function to HB Grade I at least 12 months postoperatively. RESULTS: There were six patients with intracanalicular tumors and 100 with cerebellopontine angle (CPA) tumors eligible for study. Given the few patients with intracanalicular tumors, no further analysis was pursued in this subset. For patients with CPA tumors, a multivariable analysis of several patient and tumor characteristics demonstrated age at surgery (odds ratio for 10-year increase of 0.68; 95% confidence interval [CI], 0.47-0.98; p = 0.04) and immediate postoperative HB grade (odds ratio for one-grade increase of 0.27; 95% CI, 0.15-0.50; p < 0.001) to be jointly significantly associated with complete recovery to HB Grade I, indicating that the likelihood of complete facial nerve recovery was higher for younger patients and for those with better immediate postoperative HB grades. For example, the predicted probability of complete facial nerve recovery for a 30-year-old with immediate postoperative HB Grade III was 0.76 (or 76% when expressed as a percentage), whereas the predicted probability for a 50-year-old with immediate postoperative HB Grade V was only 0.10. CONCLUSIONS: After considering immediate postoperative HB grade, younger age at surgery was independently significantly associated with complete facial nerve recovery, which can assist in intraoperative decision-making regarding extent of resection and postoperative counseling.

Animal-induced trauma can lead to severe injury and death, especially in medically isolated settings. Few reports of hyena attacks on humans have been reported in the literature. The goal of this report is to describe such an attack and the heroic efforts required to preserve life and function in a resource-limited environment. A 55-year-old female was attacked by a hyena in a rural region of Ethiopia. Despite delays in medical care, she was able to survive this attack and was successfully discharged after prolonged treatment efforts. Animal-induced trauma is a potential source of substantial and disfiguring injury, especially in resource-limited environments. Early transfer to tertiary care centers and creative solutions are needed to optimize outcomes in such environments.
RESUMO
OBJECTIVE: The differential of an external auditory canal mass is broad. One rare potential cause is a pneumatocele of the tympanic membrane, which has only been described 1 other time in the literature. This report serves to describe the second case of this pathology, including its unique presentation, and benign clinical course. METHODS: Case report. RESULTS: A case is discussed in which a pneumatocele of the tympanic membrane was incidentally identified during evaluation of contralateral otologic pathology. The etiology was suspected to be habitual auto-insufflation. After cessation of this practice, the pneumatocele was noted to resolve without further intervention. CONCLUSION: A tympanic membrane pneumatocele represents a rare cause of an external auditory canal mass. The diagnosis can be made clinically via history, palpation, and otoscopy during auto-insufflation, potentially avoiding further diagnostic testing. Depending on the etiology, resolution can occur after lifestyle modification; however, further interventions may definitively treat the condition if so required.

OBJECTIVE: To assess quality-of-life (QoL) outcomes after modified subtotal petrosectomy with ear canal closure (mSTP) for chronic otitis media. STUDY DESIGN: Survey study. SETTING: Tertiary referral center. PATIENTS: Patients with chronic otitis media. INTERVENTIONS: mSTP. MAIN OUTCOME MEASURES: Survey results from enrolled patients on the validated disease-specific Chronic Ear Survey (CES) and Chronic Otitis Media Outcome Test-15 (COMOT-15) regarding their current state of health and, if surgery was performed within 3 years of enrollment, their state of health before mSTP. RESULTS: A total of 23 patients were studied, including 19 who underwent surgery within 3 years of enrollment. Postoperatively, mean total CES scores were 80 and COMOT-15 scores were 41, with a higher CES and a lower COMOT-15 indicating better QoL. There were statistically significant improvements after mSTP in the CES activity restriction (25% difference; p = 0.008), symptom (17% difference; p = 0.007), and medical resource (13% difference; p = 0.03) domain and total (18% difference; p = 0.006) scores. In addition, there were statistically significant improvements in the COMOT-15 ear symptom (-22% difference; p < 0.001) domain and total (-16% difference; p = 0.01) scores; however, improvements in the hearing function and mental health domains did not achieve statistical significance. Postoperative COMOT-15 total scores were significantly better for patients who underwent aural rehabilitation compared to those who did not (-17% difference; p < 0.001). CONCLUSION: Modified subtotal petrosectomy with ear canal closure is a useful intervention for patients with recalcitrant chronic otitis media, offering improved QoL in appropriately selected patients. Aural rehabilitation, when feasible, provides the potential for further QoL improvement.

Background: There are few reports of dexterity tests being done in a distance telecommunication setting for residency applicant evaluation. Objective: To report the feasibility and suitability of a virtual suturing skills assessment during residency interviews when added to the standard assessment process. Methods: A suturing simulation was developed and implemented during otolaryngology-head and neck surgery (OHNS) residency interviews for the 2020-2021 cycle at one program. On the day of the interview, the activity was completed in real time using 2-camera video conferencing with the 2 resident assessors providing a numerical assessment based on an adapted scoring rubric from prior suturing activities at the institution. The exercise involved suturing a 3/4-inch Penrose drain circumferentially with half-vertical mattress stitches to simulate the maturation of a tracheostoma. The residency selection committee then completed a 7-item Likert-type survey, developed by the authors, to evaluate the simulation exercise. Results: Fifty-one applicants representing all interviewees in the cycle successfully completed this assessment without technologic disruptions. The total cost associated with obtaining and providing the necessary supplies to applicants was $34.78 per interviewee. Time required to complete the suturing task was estimated to range from 10 to 20 minutes. The residency selection committee viewed this exercise as a success (14 of 16, 87.5%) and viewed the results as a valuable adjunct in the overall assessment of candidates (15 of 16, 93.8%). Conclusions: A simple motor exercise completed over real-time telecommunication was feasible and perceived as helpful to the residency selection committee when assessing OHNS residency candidates.

OBJECTIVE: Describe the presentation and management strategy for patients with symptomatic foramen of Huschke (FH). PATIENTS: Adults with persistent FH confirmed on imaging. INTERVENTIONS: Diagnosis and management of symptomatic persistent FH. MAIN OUTCOME MEASURE: Resolution of otologic symptoms. RESULTS: A total of four patients with symptomatic, radiographically-confirmed persistent FH were included. The majority of patients endorsed otalgia (n = 4) and otorrhea (n = 3), and only one patient was noted to have a conductive hearing loss. All patients were noted to have dynamic movement of an external auditory canal mass with mandible manipulation on examination, and all patients had an identifiable fistula on imaging. Patients underwent surgical intervention, including both preauricular (n = 2) and transcanal (n = 2) approaches, and all endorsed symptomatic resolution after convalescence. CONCLUSIONS: Persistent FH remains an uncommon and potentially underrecognized cause of otologic symptoms. Diagnosis requires a high index of suspicion, and one must rely on both key examination findings and imaging to confirm this diagnosis. In appropriately selected patients, surgical intervention can provide durable symptomatic resolution. LEVEL OF EVIDENCE: IV.
RESUMO
OBJECTIVES/HYPOTHESIS: To review hearing preservation after microsurgical resection of sporadic vestibular schwannomas according to tumor size. STUDY DESIGN: Retrospective cohort. METHODS: Baseline, intraoperative, and postoperative patient and tumor characteristics were retrospectively collected for a cohort who underwent hearing preservation microsurgery. Serviceable hearing was defined by a pure tone average ≤50 dB and word recognition score ≥50%. RESULTS: A total of 243 patients had serviceable hearing preoperatively. Fifty (21%) tumors were confined to the internal auditory canal, and the median tumor size was 16.2 mm (interquartile range [IQR] 11.3-23.2) for tumors with cerebellopontine angle extension. Serviceable hearing was maintained in 64% of patients with tumors confined to the internal auditory canal, 28% with cerebellopontine angle extension <15 mm, and 9% with cerebellopontine angle extension ≥15 mm. On multivariable analysis, the odds ratios of acquiring nonserviceable hearing postoperatively for tumors extending <15 mm and ≥15 mm into the cerebellopontine angle were 5.75 (95% confidence interval [CI] 2.13-15.53; P < .001) and 22.11 (95% CI 7.04-69.42; P < .001), respectively, compared with intracanalicular tumors. CONCLUSIONS: The strongest predictor of hearing preservation with microsurgery after multivariable adjustment is tumor size. Approximately 10% of patients with tumors ≥15 mm of cerebellopontine angle extension will retain serviceable hearing after microsurgery. Furthermore, hearing preservation techniques offer cochlear nerve preservation and cochlear patency allowing for possible future cochlear implantation. An attempt at hearing preservation, including avoiding surgical approaches that necessarily sacrifice hearing, is worthwhile even in larger tumors if serviceable hearing is present preoperatively. LEVEL OF EVIDENCE: 4 Laryngoscope, 132:1657-1664, 2022.

OBJECTIVE: To evaluate the optimal dose and timing of administration of sodium fluorescein (SF) for selective fluorescence of sporadic vestibular schwannoma (VS) during microsurgery with the YELLOW 560-nm microscope filter (YE560) and to characterize the potential benefit of this fluorescence as determined by intraoperative surgeon assessment. STUDY DESIGN: Prospective cohort study. SETTING: Tertiary referral center. PATIENTS: Adult patients undergoing VS microsurgery. INTERVENTIONS: Intraoperative intravenous administration of SF and visualization with the YE560. MAIN OUTCOME MEASURES: Time to differential fluorescence, duration of fluorescence, correlation of fluorescence of VS with electrostimulation and white light microscopy visual assessment, and likelihood of surgeons to use SF with the YE560 in future cases. RESULTS: Novel use of SF and YE560 during microsurgery achieved selective fluorescence of VS with capabilities to differentiate nerve fascicles and tumor approximately 30 minutes after administration. Nuances of SF administration and timing are discussed. Seventy-five percent of surgeons observed an excellent correlation of selective fluorescence with white light microscopy. Representative images and cases are presented. CONCLUSIONS: SF and YE560 may be used in VS microsurgery to visually differentiate VS from surrounding nerves. Potential benefits include enhanced visualization of the tumor-nerve interface for tumor dissection and detection of any residual disease, such as in the fundus after hearing preservation microsurgery.
