OBJECTIVES To evaluate functional swallowing outcomes in patients undergoing transoral robotic surgery vs primary chemoradiotherapy for the management of advanced-stage oropharynx and supraglottis cancers. DESIGN Prospective nonrandomized clinical trial. SETTING Academic research. PATIENTS We studied 40 patients with stage III or stage IVA oropharynx(More)
The preoperative assessment of mandibular invasion by oral or oropharyngeal squamous cell carcinoma poses a challenge for the head and neck surgeon. A study of 64 composite resection patients was performed to determine which variables in the patient's history, physical exam, and diagnostic workup had a predictive association with carcinomatous mandibular(More)
Hair cell regeneration following acoustic trauma to the avian cochlea has been documented using DNA labeling with tritiated thymidine. The goal of this study was to identify potential precursor cell populations for regenerating hair cells. Chicks were exposed in pairs to a 1500 Hz pure tone at 120 dBSPL for 18 h. The animals received repeated injections of(More)
Tucci and Rubel have demonstrated functional recovery of the chick cochlea following aminoglycoside ototoxicity. The cochleae of these same animals were examined by scanning electron microscopy (SEM) in order to further understand this recovery process. Hatchling chicks were given daily doses of gentamicin for 10 days. Auditory-evoked potential measurements(More)
Damage to inner ear sensory hair cells after systemic administration of ototoxic drugs has been documented in humans and animals. Birds have the ability to regenerate new hair cells to replace those damaged by drugs or noise. Unfortunately, the systemic administration of gentamicin damages both ears in a variable fashion with potentially confounding(More)
The effectiveness of local anesthetics is improved by the addition of a vasoconstrictor which increases duration of action and decreases both systemic toxic reactions and local bleeding. Epinephrine, the standard drug for vasoconstriction, has some limitations due to potential dose-related cardiac and local toxic effects. The authors examined the minimal(More)
BACKGROUND AND PURPOSE Percutaneous ethanol sclerotherapy has been reported to be efficacious for head and neck venous malformations. We sought to evaluate the safety and efficacy of percutaneous sclerotherapy by using ethanol for treatment of symptomatic venous malformations of the tongue. METHODS Eleven sclerotherapy procedures were performed in seven(More)
This case report describes false-positive positron-emission tomography/computed tomography (PET/CT) findings related to oral prostheses and its implications in cancer surveillance. In head and neck cancer management, F18-flurodeoxyglucose (FDG) PET/CT is widely accepted for evaluating treatment response and detecting recurrence. Interpretation of FDG PET/CT(More)
OBJECTIVE Our goal was to evaluate our experience with radiation-induced malignancy (RIM), compare that experience to the literature, and review treatment modalities. STUDY DESIGN AND SETTING The setting is the University of Kansas Medical Center. A retrospective review was performed to identify patients with RIM. Patients were included if they met the(More)
BACKGROUND Pulmonary complications are a primary source of increased cost and morbidity in surgically treated head and neck cancer patients. This study investigates potential risk factors related to postoperative pulmonary complications (pneumonia, adult respiratory distress syndrome (ARDS), and prolonged mechanical ventilation) in head and neck cancer(More)
