Reconstruction after temporal bone resection.

Reconstruction of soft tissue defects after temporal bone resection can vary from simple closure of the external auditory canal to complex flap coverage of extensive defects. Between 1987 and 1996, 34 patients underwent lateral skull base resections and reconstruction for invasive carcinoma of the temporal bone. Seven underwent sleeve resection and/or radical mastoidectomy. Sleeve resection was managed with tympanoplasty, canalplasty, or obliteration of the external auditory canal (10). There were 24 lateral temporal bone resections and four subtotal temporal bone resections. Larger defects created by lateral and subtotal temporal bone resections required closure with a combination of temporalis flaps and local rotational cutaneous flaps (13). Lower island trapezius flaps (five), free flaps (four), and pectoralis major flaps (two) were also used. Indications and efficacy of each method are discussed, and treatment outcomes are presented.

The effect of topical vasodilating agents on microvascular vessel diameter in the rat model.

Topical vasodilating agents maximize blood flow and prevent vasospasm in microvascular tissue-transfer procedures. Two commonly used agents are papaverine and lidocaine. Although these drugs have vasodilating properties, no studies have directly compared their vasodilating abilities in a controlled, in vivo model. We used videomicroscopy and direct microscopic measurements to compare the vasodilating capacity of papaverine, 1% lidocaine, and saline solution in the femoral artery of Sprague-Dawley rats. Degree of maximum dilation, ability to sustain dilation, average dilation over a 10-minute period, and time to achieve maximum dilation were considered. Both papaverine and lidocaine were found to be superior to saline solution as vasodilating agents. Papaverine was found to sustain vasodilation longer than lidocaine, suggesting that it is a superior vasodilating agent in microvascular anastomoses.

Laryngeal cryptococcus. Treatment with oral fluconazole.

We treated a case of laryngeal Cryptococcus neoformans infection in a glucocorticosteroid-dependent patient with chronic obstructive pulmonary disease. To our knowledge, this is the first report of successful treatment of laryngeal cryptococcus using oral fluconazole as a single agent.
