Effect Of Head Coverings On Directional Microphone Performance In Modern Hearing Aids: A Kemar-Based Laboratory Evaluation, Zahra Fekri, Mariam Mohamad, Ayasakanta Rout

Faculty Scholarship

Background/Objectives: Directional microphones are an established hearing aid technology for improving speech understanding in background noise. Although researchers have examined the influence of hair, spectacles, and earmold venting on directional performance, no systematic work has addressed head coverings, which people wear worldwide for cultural, religious, occupational, and personal reasons. This study determined whether a cotton head covering alters the directivity index (DI) of highest-level receiver-in-canal (RIC) hearing aids. Methods: A Knowles Electronics Manikin for Acoustic Research (KEMAR) was positioned in a double-walled, sound-treated booth, and DI was measured for omnidirectional and fixed directional microphone settings, with and without a two-layer …

Patient-Specific Computational Fluid Dynamics Modeling Of Airway Collapse In Infants With Robin Sequence., Gautam Jalori, Michael Barbour, Michael Bindschadler, Kelly Evans, John P. Dahl, Alberto Aliseda

Manuscripts, Articles, Book Chapters and Other Papers

Robin Sequence (RS) is a congenital condition in which patients experience dynamic, periodic obstruction or collapse of the upper airway due to an underdeveloped jaw and a posteriorly displaced tongue. Current clinical techniques for evaluating airway obstruction do not provide quantifiable data and fail to account for the dynamic nature of obstruction or collapse. There is no standardized criterion to characterize obstruction or collapse severity. This study presents the first method that extracts airway motion from 4-dimensional computed tomography and performs a patient-specific, moving-mesh computational fluid dynamics (CFD) analysis of RS patients with complete airway collapse or obstruction. To quantify …

Should H2-Blockers Be Used For The Treatment Of Laryngopharyngeal Reflux?, Sophia Linguiti, W. Jack Palmer, Janvi J. Shukla, Kathleen Tibbetts, Colin Huntley, Joseph Spiegel

Department of Otolaryngology - Head and Neck Surgery Faculty Papers

Laryngopharyngeal reflux (LPR) is a highly prevalent condition in otolaryngology practice, characterized by reflux of gastric contents into the pharynx and larynx. Although proton pump inhibitors (PPIs) remain first-line therapy, many patients report persistent symptoms. In refractory cases, histamine-2 receptor antagonists (H2RAs) are often employed as adjunctive or standalone therapy due to their rapid onset and accessibility. However, their utility as daily therapy is limited by tachyphylaxis, with significant loss of acid suppression within days of continuous use. Despite longstanding evidence from gastroenterology literature discouraging daily H2RA therapy, these agents remain frequently prescribed in otolaryngology practice. Contemporary ear, nose, and …

Definitive Radiation Therapy For Schneiderian Inverted Papilloma Of The Soft Palate And Uvula., Rahul Sinha, Arianne J Abreu, Christopher E Fundakowski, Robert T Sataloff

Otolaryngology (ENT) Resident Research

Schneiderian inverted papilloma is a benign, locally aggressive tumor that typically arises in the respiratory mucosa of the nasal cavity and paranasal sinuses. These tumors are often asymptomatic but can cause unilateral nasal obstruction, discharge, hyposmia and epistaxis. They warrant attention particularly due to the potential for malignant transformation. They are treated most often with surgical excision. This case report describes a patient with Schneiderian inverted papilloma arising outside its usual location and managed with definitive radiation therapy instead of surgical excision due to concerns for functional impairment. Remission was obtained with radiation therapy, although the patient experienced treatment-related side …

Elmorsi, Tuyen Phan, Indrajit Chaudhury, Tom Corbiere, Lindsey B. Collins, Elizabeth B. Hirsch, Benjamin A. Weinberg, Jennifer M. Johnson, Emmanuel S. Antonarakis, Emil Lou, R. Stephanie Huang

Department of Otolaryngology - Head and Neck Surgery Faculty Papers

The intratumoral microbiome is increasingly recognized as a regulator of cancer biology, yet sex-specific patterns and their relevance to cancer disparities remain poorly understood. We perform a multi-kingdom analysis of more than 5,000 tumors from seven datasets to identify sex-differential microbial taxa across aerodigestive and gastrointestinal cancers. We identify and validate 22 taxa with consistent sex-biased abundance, including in real-world cohort. These microbes show cancer-type- and microbe-specific associations with tumor transcriptomes, oncogenic pathways, and immune cell infiltration. Female-enriched microbes are linked to increased estrogen signaling and interferon responses, whereas male-enriched taxa show opposing patterns. In gastric cancer, intratumoral Epstein-Barr virus …

Department of Otolaryngology - Head and Neck Surgery Faculty Papers

Multifocal papillary thyroid cancer (PTC) can arise from independent primaries with discordant drivers in parallel clonal evolution rather than a single-clone pattern. We present a 31-year-old female with multifocal PTC harboring 3 distinct oncogenic alterations: a germline RET p.V804M mutation, low-frequency EML4-ALK fusion, and BRAF V600E mutation. The RET and ALK alterations were identified in a midpole nodule, whereas BRAF positivity was seen in a separate lower pole tumor. Ultrasound revealed multiple right-lobe thyroid nodules; the dominant 2.1-cm lesion was hypoechoic with calcifications. Fine needle aspiration revealed Bethesda III cytology, prompting thyroid lobectomy and an ipsilateral central neck dissection was …

Bilateral Vocal Process Avulsion: A Rare Complication Of Laryngeal Trauma., Hye Rhee Chi, Omar Ramadan, Robert T Sataloff

Otolaryngology (ENT) Resident Research

Vocal process avulsion is a rare and often overlooked complication of laryngeal trauma, most commonly associated with endotracheal intubation. It involves detachment of the vocal process from the body of the arytenoid cartilage, leading to dysphonia, dysphagia, voice fatigue, and/or aspiration. While strobovideolaryngoscopy and laryngeal electromyography may suggest underlying structural disruption, diagnosis can be challenging when findings are subtle or imaging is inconclusive. Definitive diagnosis and management typically involves surgical evaluation and repair to restore vocal fold tension and glottic competence. We present the first documented case of bilateral vocal process avulsion following endotracheal intubation.

Exploring Adolescent Hearing Aid Usage And Appearance Of Psychiatric Symptoms In Adolescents Using Hearql-28 Surveys, Courtney J. Austin, Dylan Chan

MEDI 9331 Scholarly Activities Clinical Years

Approximately 2% of DHH people in need of mental health services actually receive these services. Among pediatric hearing loss populations, co-occurring cognitive and physical impairments are risk factors for poor mental health status. Due to language barriers and isolation, more children with hearing loss do not have access to mental health services. Cochlear implants have been shown to improve mental health status among the DHH population. Current literature focuses on the mental health status of children with cochlear implants, with little focus on hearing aid users. Using HEAR28 data and surveys, we can quantify the incidence of psychiatric symptoms among …
