RESUMO
OBJECTIVE: To present our experience in the management of paranasal sinus osteomas. MATERIAL AND METHODS: We review 14 patients with frontoethmoidal osteomas removed in our hospital between 1988-2001. The initial symptoms, site and size of the lesions, surgical approaches and short and long term complications were assesed. RESULTS: The most common symptom in our series was headache (57%); most of the tumors were located in frontal (35%) and frontoethmoidal (35%) regions with a mean size of 4.2 cm (maximum diameter) at the time of surgery. All symptomatic osteomas were resected by classic external surgical approaches but two cases were removed by endonasal surgery. DISCUSSION: Although osteomas are benign tumors, they may enlarge progressively and produce complications. Their resection is not free of risks, so there is some controversy about the management of asymptomatic patients. Endonasal surgery reduces the morbidity of the treatment but the location and size of the lesions do not allow to employ this technique in all cases.

Thyroplasty type I has provided significant improvement to the treatment of patients with glottal incompetence. It is essential that patients be preoperatively evaluated using objective criteria. Laryngeal manual compression test are manipulations of the thyroid and cricoid cartilages that result in modifications of the position of the vocal folds. The most valuable laryngeal manual compression test for patients with glottal insufficiency is the lateral compression test. When this test results in a preoperative improvement in voice suggest that surgery will be successful. In this paper we present the objective evaluation of the effects of lateral compression test upon glottic incompetence by means of narrow band power spectrum analysis.
