Minifenestration type I thyroplasty using an expanded polytetrafluoroethylene implant.

Several methods have been used to treat laryngeal incompetence, but no ideal technique has been identified. This paper describes a clinical experience with minifenestration type I thyroplasty using a new device made of expanded polytetrafluoroethylene (ePTFE). The device, a thin ribbon of ePTFE, is inserted through a 4-mm fenestration to produce vocal fold medialization. At our center, 26 of these devices have been implanted in the past 3 years. Good or satisfactory results were achieved in 96% of cases. Advantages of this technique include easy insertion of the implant, nominal cost and biocompatibility of the ePTFE device, ready availability of all instruments required for the procedure, and elimination of the need to perform arytenoid adduction.

Predictors of weight loss during radiation therapy.

OBJECTIVE: To define risk factors for weight loss or dehydration during radiation therapy (RT). STUDY DESIGN AND SETTING: Retrospective chart review, academic tertiary care center. RESULTS: The incidence of severe weight loss during RT was 32.7%, the incidence of dehydration was 10.9%, and the rate of prophylactic feeding gastrostomy tube placement was 32%. The patients most likely to suffer severe weight loss included patients with tumor sites of nasopharynx and base of tongue, those treated with chemoradiation, and patients with severe pretreatment weight loss. Prophylactic feeding gastrostomy tube placement before RT significantly reduced the incidence of severe weight loss and hospitalization during RT. CONCLUSION: Severe weight loss and dehydration during RT for head and neck cancer is common. Prophylactic feeding gastrostomy tubes significantly reduce the incidence of severe weight loss and hospitalization for dehydration during RT when placed before onset of RT. Patients at risk for severe weight loss include those with severe pretreatment weight loss, tumors of the nasopharynx and base of tongue, or treatment with chemoradiation.

Calcifying fibrous pseudotumor of the neck.

Calcifying fibrous pseudotumor is a rare lesion of uncertain histogenesis that has a unique histologic appearance. We report herein a case of a 24-year-old woman with a mass on the right posterior side of the neck. Magnetic resonance imaging with contrast showed a well-circumscribed mass between the right splenius and semispinalis cervicis muscles; the study suggested high collagen content. Simple excision was performed. The histologic findings were diagnostic of calcifying fibrous pseudotumor. Our review of 19 previously reported cases suggests that a good outcome is expected when a diagnosis of calcifying fibrous pseudotumor is made.

Percutaneous fluoroscopic gastrostomy tube placement in patients with head and neck cancer.

OBJECTIVE: To study the safety and efficacy of percutaneous fluoroscopic gastrostomy tube placement in patients with head and neck cancer. DESIGN: We conducted a retrospective case review of 92 consecutive cases. Comparable access procedures and relevant literature were reviewed. SETTING: Academic tertiary care center. PATIENTS: Patients with head and neck cancer who underwent percutaneous fluoroscopic gastrostomy tube placement between January 1996 and July 1996. MAIN OUTCOME MEASURES: Immediate, delayed, and long-term complications; tube malfunction; and tube placement failure. RESULTS: The major complication rate was 1%; the minor complication rate was 8%; and the tube malfunction rate was 13%. The rate of successful tube placement was 98%. None of the patients required hospitalization as a result of the procedure. CONCLUSIONS: Percutaneous fluoroscopic gastrostomy tube placement is a safe, economical, and comfortable method that has distinct advantages over other gastrostomy tube placement methods. It is recommended for enteral feeding and nutritional supplementation in patients with head and neck cancer.
