The Relationship Between Insertion Angles, Default Frequency Allocations, And Spiral Ganglion Place Pitch In Cochlear Implants, D. M. Landsberger, M. Svrakic, J. T., Jr. Roland, M. Svirsky

Journal Articles

OBJECTIVES: Commercially available cochlear implant systems attempt to deliver frequency information going down to a few hundred Hertz, but the electrode arrays are not designed to reach the most apical regions of the cochlea, which correspond to these low frequencies. This may cause a mismatch between the frequencies presented by a cochlear implant electrode array and the frequencies represented at the corresponding location in a normal-hearing cochlea. In the following study, the mismatch between the frequency presented at a given cochlear angle and the frequency expected by an acoustic hearing ear at the corresponding angle is examined for the cochlear …

Kimura’S Disease Of Head And Neck: A Rare Case Presentation, Talha Ahmed Qureshi, Moghira Siddiqui, Muhammad Tariq

Department of Surgery Docs

Kimura's disease (KD) is a rare, unusual occurrence, predominantly seen in Asian men, and poses a diagnostic challenge, often manifesting with allergic, eosinophilic hyperplasia, and nonspecific lymphadenitis. A 39-year-old man presented with mobile, well circumscribed, facial and neck swelling. His earlier biopsy showed a reactive lymph node hyperplasia on ultrasound neck and was suggestive of lipomatosis. As definitive diagnosis could not be made, the patient was planned for excision and biopsy. Subsequent histopathology demonstrated eosinophilic infiltration of lymphoid follicles and expansion of interfollicular area with interfollicular eosinophilic abscess formation and capillary venule proliferation. This was quite interesting as the previously …

Epithelial Cells Are Active Participants In Vocal Fold Wound Healing: An In Vivo Animal Model Of Injury, Ciara Leydon, Mitsuyoshi Imaizumi, Rebecca S. Bartlett, Sarah F. Wang, Susan L. Thibeault

Communication Disorders Faculty Publications

Vocal fold epithelial cells likely play an important, yet currently poorly defined, role in healing following injury, irritation and inflammation. In the present study, we sought to identify a possible role for growth factors, epidermal growth factor (EGF) and transforming growth factor-beta 1 (TGFβ1), in epithelial regeneration during wound healing as a necessary first step for uncovering potential signaling mechanisms of vocal fold wound repair and remodeling. Using a rat model, we created unilateral vocal fold injuries and examined the timeline for epithelial healing and regeneration during early and late stages of wound healing using immunohistochemistry (IHC). We observed time-dependent …

Ent Educational Patient Bedside Tool, Alina M. Toma

Master's Projects and Capstones

Early educational and discharge preparations are an advantage to patients, the interdisciplinary team, and hospital. It was determined that lack in communication and coordination among staff members led to inadequate patient teaching, therefore an educational tool that is kept at the bedside may facilitate accountability and smoother transition to home.

The aim of the project is to improve the education of patients with tracheostomies and laryngectomies, and enhance staff communication and coordination by December 2014.

Analysis methods used included Failure Mode Effects Analysis (FMEA), fishbone diagram, process map, and SWOT analysis. The social learning theory is the framework chosen for …

Department of Otolaryngology - Head and Neck Surgery Presentations and Grand Rounds

NUT midline carcinoma is a rare, highly aggressive tumor that involves midline structures, particularly in the head, neck and mediastinum. It is characterized by NUT gene translocations on chromosome 15. It typically impacts teenagers or young adults, and has a fulminant course leading to death in less than a year in most cases despite aggressive chemoradiotherapy. Due to its location, this tumor is frequently considered inoperable. We present a case of a sinonasal NUT midline carcinoma with orbital invasion discovered during the workup of sinusitis in a young, pregnant woman. The tumor was managed with definitive excision to negative margins …

Department of Otolaryngology - Head and Neck Surgery Presentations and Grand Rounds

Dysphagia is a common sequela of the treatment of head and neck cancer and is frequently managed with esophageal dilation in patients with dysphagia secondary to hypopharyngeal stenosis. Reported complications of esophageal dilation include bleeding, esophageal perforation, and mediastinitis. We examine four cases of cervical spine osteomyelitis presenting as a delayed complication of esophageal dilation for hypopharyngeal stenosis in patients with a history of laryngectomy or pharyngectomy and radiation with or without chemotherapy. The history of head and neck surgery and radiation in these patients further complicates the management of the cervical spine osteomyelitis.

Postoperative Non-Steroidal Anti-Inflammatory Drugs And Risk Of Bleeding In Pediatric Intracapsular Tonsillectomy, Jill N. D'Souza, Md, Julie P. Adelman, Bs, Richard J. Schmidt, Md, Heather C. Nardone, Md

Department of Otolaryngology - Head and Neck Surgery Presentations and Grand Rounds

Tonsillectomy with or without adenoidectomy is one of the most frequently performed surgeries in the United States, with over 500,000 performed annually. Post-tonsillectomy hemorrhage is one of the most feared complications; thus, medications that could increase the risk of postoperative bleeding traditionally have been avoided. With recent FDA guidelines encouraging a departure from codeine-based medications in pediatric patients undergoing tonsillectomy, we examined the use of ibuprofen for post-tonsillectomy pain control. The records of 449 children who underwent tonsillectomy and received ibuprofen for postoperative pain control were reviewed and compared to a cohort of 1731 children who received codeine for pain …

Nasal T Cell Lymphoma: A Rare Entity, Maliha Kazi, Mubasher Ikram, Montasir Junaid

Section of Otolaryngology, Head & Neck Surgery

Nasal type of Natural Killer (NK)/T cell lymphoma manifests in the nasal cavity. Approximately 95% of them are associated with EBV(Ebstein Barr Virus) with a strong predilection for the Asian population. It has certain systemic and localized symptoms which aid in diagnosis of the condition. However, the histological criteria is pivotal in confirming the diagnosis as well as aiding in confirming the association of EBV. Nasal type of NK/T cell lymphoma has a guarded prognosis. Treatment plan include radiotherapy with concurrent chemotherapy. Despite all this, the 5-year survival rate ranges from 15-75%. A 35 years old male presented with an …

METHODS: A parotid gland surgical resection model for xenografting was developed. Salivary cells loaded in HA hydrogels formed spheroids and in vitro were implanted in the three-fourths resected parotid bed of athymic …

Laryngeal Myxoma: A Case Report And Review Of The Literature, A. Ritchie, J. Youngerman, J. E. Fantasia, L. B. Kahn, R. S. Cocker

Journal Articles

Myxomas are a rare benign neoplasm of uncertain mesenchymal cell origin, typically involving the heart. Laryngeal myxomas are uncommon, and are usually misdiagnosed as laryngeal polyp. To the best of our knowledge, there are only nine reported cases in the English literature. We report a case of a laryngeal myxoma presenting clinically as a left vocal cord polyp in a 77 year old male, and review the literature related to this rare entity.

Decreased Langerhans Cell Responses To Il-36 Gamma: Altered Innate Immunity In Patients With Recurrent Respiratory Papillomatosis, J. Devoti, L. Hatam, A. Lucs, A. Afzal, A. Abramson, B. M. Steinberg, V. Bonagura

Journal Articles

Recurrent respiratory papillomatosis (RRP) is a rare, chronic disease caused by human papillomaviruses (HPVs) types 6 and 11 that is characterized by the polarization of adaptive immune responses that support persistent HPV infection. Respiratory papillomas express elevated mRNA levels of IL-36 gamma, a proinflammatory cytokine in comparison to autologous clinically normal laryngeal tissues; however there is no evidence of inflammation in these lesions. Consistent with this, respiratory papillomas do not contain T(H)1-like CD4(+) T-cells or cytotoxic CD8(+) T-cells, but instead contain a predominance of T(H)2-like and T regulatory cells (Tregs). In addition, papillomas also are infiltrated with immature Langerhans cells …

Journal Articles

BACKGROUND:Internal maxillary artery (IMax)-middle cerebral artery (MCA) bypass has been recently described as an alternative to cervical extracranial-intracranial bypass. This technique uses a keyhole craniectomy in the temporal fossa that requires a technically challenging end-to-side anastomosis.OBJECTIVE:To describe a lateral subtemporal craniectomy of the middle cranial fossa floor to facilitate wide exposure of the IMax to facilitate bypass.METHODS:Orbitozygomatic osteotomy is used followed by frontotemporal craniotomy and subsequently laterotemporal fossa craniectomy, reaching its medial border at a virtual line connecting the foramen rotundum and foramen ovale. The IMax was identified by using established anatomic landmarks, neuronavigation, and micro Doppler probe (Mizuho Inc. …

Early Efficacy Trial Of Anakinra In Corticosteroid-Resistant Autoimmune Inner Ear Disease, A. Vambutas, M. Lesser, V. Mullooly, S. Pathak, G. Zahtz, L. M. Rosen, E. Goldofsky

Journal Articles

BACKGROUND. Autoimmune inner ear disease (AIED) is a rare disease that results in progressive sensorineural hearing loss. Patients with AIED initially respond to corticosteroids; however, many patients become unresponsive to this treatment over time, and there is no effective alternative therapy for these individuals. METHODS. We performed a phase I/II open-label, single-arm clinical trial of the IL-1 receptor antagonist anakinra in corticosteroid-resistant AIED patients. Given that the etiology of corticosteroid resistance is likely heterogeneous, we used a Simon 2-stage design to distinguish between an unacceptable (= 30%) response rate to anakinra therapy. Subjects received 100 mg anakinra by subcutaneous injection …
