BACKGROUND Pleomorphic adenoma (PA) is the most common benign neoplasm of the major salivary glands. PA of the paranasal sinuses and skull base is an extremely rare pathologic entity. We report 3 cases of sinonasal and skull-base PA (including locoregionally advanced parotid disease) and review other cases in the literature, with special attention to(More)
OBJECTIVE Determine the efficacy of a swallow preservation protocol (SPP) on maintaining swallow function in patients undergoing chemoradiation (CRT) or radiation therapy alone (RT) for head and neck squamous cell carcinoma (HNSCC). STUDY DESIGN Retrospective case series. SETTING Veterans Affairs medical center. SUBJECTS AND METHODS Patients treated(More)
OBJECTIVE To describe the incidence and determinants of survival of patients with sinonasal undifferentiated carcinoma (SNUC) from 1973 to 2011 using the SEER database (Surveillance, Epidemiology, and End Results), with consideration of tumor stage based on the Kadish system. STUDY DESIGN Retrospective database analysis. SETTING Academic medical center.(More)
OBJECTIVE Following our preliminary study on junior medical students' comfort levels in performing the head and neck physical examination (H&NPE) before and after a department-led teaching session, we assessed the longitudinal effect of this session on students during the core clinical clerkship year, in which these skills were performed on real patients.(More)
OBJECTIVES/HYPOTHESIS Electromechanical reshaping (EMR) involves reshaping cartilage by mechanical deformation and delivering electric current to the area around the bend axis, causing local stress relaxation and permanent shape change. The mechanism of EMR is currently unclear, although preliminary studies suggest that voltage and application time are(More)
OBJECTIVES/HYPOTHESIS Obstructive sleep apnea syndrome (OSAS) is a common adult and pediatric sleep disorder, which, if left untreated, is associated with severe medical consequences. Otolaryngologists are often challenged by the impact of OSAS on sinonasal symptoms, as well as by the contribution of primary nasal disorders to exacerbation of OSAS. The(More)
BACKGROUND Retromaxillary air cells (RMC) are posterior ethmoid cells that separate the maxillary and ethmoid sinuses. The clinical significance of these cells in contributing to revision functional endoscopic sinus surgery (FESS) is unknown. OBJECTIVES To investigate the prevalence, anatomic dimensions, and radiographic characteristics of RMC in patients(More)
OBJECTIVES Acromegalics present with a wide range of otolaryngic symptoms, including rhinosinusitis, changes in facial appearance, obstructive sleep apnea (OSA), and voice disturbances. Treatment typically involves transnasal-transsphenoidal (TNTS) resection of the offending pituitary adenoma. In this study, we identify the prevalence of otolaryngic(More)
BACKGROUND Staphylococcus pseudintermedius is a gram-positive bacterium commonly found as part of the normal skin and nasal flora of healthy dogs. It may act as an opportunistic pathogen in dogs, but has also been shown to colonize the nasal mucosa of humans. We report 4 cases of chronic rhinosinusitis (CRS) refractory to aggressive medical management with(More)
A tender neck mass in adults can be a diagnostic challenge due to a wide differential diagnosis, which ranges from reactive lymphadenopathy to malignancy. In this report, we describe a case of a young female with an unusually large and tender reactive lymph node with fat necrosis. The diagnostic imaging findings alone mimicked that of scrofula and(More)
