Vestibular Schwannoma Presenting with Cough-Induced Vertigo.

Vestibular schwannomas often present with unilateral hearing loss, tinnitus, or dizziness. Imaging is commonly pursued in individuals with unexplained unilateral sensorineural hearing loss, deterioration in word recognition scores, or persistent tinnitus. We present the case of a 76-year-old male with cough-induced vertigo as his primary presenting symptom. Vestibular testing suggested a right vestibular hypofunction, and a small right-sided vestibular schwannoma was discovered using magnetic resonance imaging. Cough-induced vertigo and associated nystagmus may be a presenting feature of vestibular schwannoma.

Impact of Giving Patients Your Personal Phone Number in Otolaryngology-Head & Neck Surgery.

OBJECTIVE: Patient-provider communication is a major barrier to care, with some providers giving their personal phone number (PPN) to patients for increased accessibility. We investigated participant utilization of provider's PPN, its effect on participant satisfaction, provider's ability to predict abuse of this practice, and evolving provider perceptions. STUDY DESIGN: Prospective, randomized study. SETTING: Single institution, tertiary referral center. METHODS: During a 2-week period, otolaryngology patients were randomized to either receive their provider's PPN or not. Providers predicted the likelihood of abuse. All calls/texts were documented for 4 weeks. At the study's conclusion, participants were surveyed using Press Ganey metrics. Providers were surveyed before and after to assess their likelihood of providing patients with their PPN and its impact on work demands. RESULTS: Of the 507 participants enrolled, 266 were randomized to the phone number group (+PN). Of 44 calls/texts from 24 participants, 8 were considered inappropriate. Ten participants were predicted to abuse the PPN, but only one was accurately identified. Participants in the +PN group had a greater mean composite satisfaction score than the control group (4.8 vs 4.3; Welch's t-test, P < .0011). At the conclusion of the study, providers were more likely to share their PPN (Wilcoxon signed-rank test, P < .0313), and their perceived impact of this practice on workload was lower (Wilcoxon signed-rank test, P < .0469). CONCLUSION: This study demonstrates low patient utilization of provider PPNs, and poor provider predictive ability of patient abuse. Receipt of provider's PPN was associated with improved patient satisfaction.

Successful Cochlear Implantation in the Face of Persistent Stapedial Artery: Surgical Technique and Imaging Features.

The stapedial artery is an embryologic structure that very rarely persists into adulthood. Termed the persistent stapedial artery (PSA), it is most often asymptomatic, identified retrospectively, and can complicate middle ear surgery. A 70-year-old woman presented with profound bilateral sensorineural hearing loss and elected to undergo cochlear implantation. During surgery, a pulsatile, cord-like structure was found obscuring the round window niche. A high-resolution computed tomography (HRCT) imaging review confirmed PSA diagnosis. A cochleostomy was made using a cochleostomy burr and gentle vessel compression. Complete insertion of the cochlear implant was achieved and its placement confirmed. The patient went on to develop open-set discrimination. We report the first successful case of cochlear implantation in the face of a PSA. Inverted HRCT imaging was found to enhance PSA visualization and may aid preoperative diagnosis. A cochleostomy technique is recommended for electrode insertion to minimize the risk of bleeding.

Membranous or Hypermobile Stapes Footplate: A New Anatomic Site Resulting in Third Window Syndrome.

Objectives: To describe a potentially underappreciated pathology for post-traumatic persistent intractable dizziness and third window syndrome as well as the methods to diagnose and surgically manage this disorder. Study Design: Observational analytic case studies review at a tertiary care medical center. Methods: Patients suffering persistent dizziness following head trauma and demonstrating Tullio phenomena or Hennebert signs are included. All had reportedly normal otic capsules on high resolution temporal bone CT scans (CT). The gray-scale invert function was used to visualize the stapes footplate, which helped determine the diagnosis. Gray-scale inversion can be used to improve visualization of temporal bone anatomy and pathologic changes when diagnoses are in doubt. A search to check for the presence of perilymph leakage was performed in all cases. This was accomplished using intraoperative Valsalva maneuvers. Fat grafting of round and oval windows was performed. Results: Over an 11-year period between January 2009 and December 2019, 28 patients (33 ears) were treated. Follow-up with balance testing and audiograms were performed 6-8 weeks following surgery. Follow-up ranged from 6 months to 7 years. Prior to surgery all patients reported dizziness in response to loud sounds and/or barometric pressure changes. Seven out of 33 ears had demonstrable perilymph leakage into the middle ear; the rest (26 ears) appeared to have membranous or hypermobile stapes footplates. Membranous stapes footplates were better visualized using the invert function on CT. Thirteen patients had a fistula sign positive bilaterally while 15 had unilateral pathology. Twenty-four of the 28 patients (85.7%) showed both subjective and objective improvement following surgery. No patients suffered from a deterioration in hearing. Conclusions: A previously underappreciated membranous or hypermobile stapes footplate can occur following head trauma and can cause intractable dizziness typical of third window syndrome (TWS). Durable long term success can be achieved by utilizing fat graft patching of the round and oval windows. High resolution temporal bone CT scans using the gray-scale inversion (invert) function can assist in preoperative diagnosis.

The changing face of petrous apicitis-a 40-year experience.

OBJECTIVES/HYPOTHESIS: Petrous apicitis (PA) is a rare complication of otitis media. Gradenigo syndrome, with the classic triad of otitis, deep pain, and abducens paralysis, is rarer still. The objective of this study was to determine if clinical presentation and management has changed over time. STUDY DESIGN: Retrospective chart review. METHODS: Forty-four patients with PA over a 40-year period were studied. Symptoms, signs, and management outcomes were studied. Historical review, surgical anatomy and approaches, pathology, and microbiology, and an illustrative case are included as appendices. RESULTS: The classical Gradenigo triad of retro-orbital pain, otitis, and abducens palsy occurred in only six of 44 patients (13.6%). Over the 40-year observation period, those needing surgery has decreased. CONCLUSIONS: Antibiotics remain the primary treatment modality. Surgery is reserved for cases failing to respond to antibiotics. One of the 44 patients in this series died of his disease. Diagnosis and management algorithms based on these observations are suggested. LEVEL OF EVIDENCE: 4. Laryngoscope, 128:195-201, 2018.

Multiple pilomatrixomas: case report and literature review.

Pilomatrixoma is a rare, benign, circumscribed, calcifying epithelial neoplasm that is derived from hair matrix cells. Multiple pilomatrixomas are uncommon. We describe a case of multiple pilomatrixomas in a 23-year-old black woman who presented with lesions on her face and back. Based on the results of the clinical examination, she was provisionally diagnosed with either calcified sebaceous cysts or calcified lymph nodes. She underwent surgical excision of the masses. On histopathology, the lesions were identified as pilomatrixomas. We attribute our original failure to diagnose this condition to our lack of familiarity with it. We discuss the presentation, differential diagnosis, and other characteristics of pilomatrixomas.

Intraoperative monitoring and facial nerve outcomes after vestibular schwannoma resection.

OBJECTIVE: To determine the predictive value of proximal facial nerve electrical threshold and proximal-to-distal facial muscle compound action potential amplitude ratio on facial nerve outcomes after resection of vestibular schwannomas. STUDY DESIGN: Retrospective case review. SETTING: Tertiary care hospital. PATIENTS: Two hundred twenty-nine patients undergoing resection of vestibular schwannomas with intraoperative facial nerve monitoring at a single institution. INTERVENTION: All patients underwent resection of vestibular schwannomas with the use of intraoperative monitoring. MAIN OUTCOME MEASURE: Facial nerve function was classified according to the House-Brackmann scale at the patient's last office follow-up. Last follow-up was at least 6 months after surgery. RESULTS: Good facial nerve function (House-Brackmann Grade I or II) was observed in 87% of the patients at their last office follow-up. Proximal-to-distal amplitude ratio and proximal electric threshold were statistically significant in predicting facial nerve outcome. A mathematical model predicting the probability of good outcome on the basis of the intraoperative parameters is presented. CONCLUSION: Intraoperative monitoring has significantly decreased facial nerve morbidity in vestibular schwannoma surgery. Despite the advances in surgery and monitoring, a group of patients still have poor facial nerve outcomes. The use of intraoperative nerve monitoring may be able to predict poor long-term facial nerve outcomes and thus modify the timing of rehabilitation.
