    Introduction: Fronto-ethmoidal osteomas are the most frequent paranasal sinus benign tumor and they may envolve with either infectious complications and destruction of adjacent structures. Though they are relatively frequent, few of them are cases requiring surgery. Aim: To report on a group of nine patients with frontal or ethmoidal osteoma, as well as to discuss the clinical presentation and the most suitable treatment of this disease. Study design: Clinical prospective. Material and Method: A prospective clinical study of nine patients who were submitted to surgery at the HSPE-FMO (State Public Servants Hospital) of São Paulo, and at the São Luiz Hospital of the city of São Paulo, in the period from 1995 to 1999. The surgical treatment was the therapeutic option selected in this group. The clinical evolution was assessed during the postoperative period. Results: Of the nine patients, five were females and four a male, ages ranging from 12 to 55 years, with an average age of 39,55 years. All the patients had a resolution of the symptoms and only one of them presented sequels (hyposmia). Conclusion: Based on both the literature review and on the cases followed, the authors concluded that the lesions compromising the drainage of the frontal sinus osteos, those with destruction of the sinus limits as well as any ethmoidal tumors should be surgically treated.

    Variações anatômicas e sinusopatias: estudo por tomografia computadorizada

    Introduction: Computed tomography has been increasingly used both to identify and to evaluate anatomy variations of nasal cavities that can lead to the development of sinusitis. Purpose: The purpose of the present study is to determine the incidence of mucosal abnormalities in paranasal sinuses found in CT scans of patients with symptons of sinusitis and analyze the correlation between sinusitis and presence of Haller's cell, concha bullosa and nasal septal deviation located in middle meatus. Study Design: Clinical retrospective. Material and Method: Paranasal sinus CT scans were obtained in 150 patients aged 13 years or more, from July 1999 to October 2001. The CT scans were performed in the Department of Radiology of Universidade Federal de São Paulo (UNIFESP) - Escola Paulista de Medicina. Patients with history of skull base or sinus surgery and tumor in these regions were excluded. Results: 70% of patients present mucosal abnormalities at least in one paranasal sinus. Maxillary sinusitis were observed in 52,7% of sinus, ethmoidal sinusitis in 28,0%, sphenoidal sinusitis in 13,0% and frontal sinusitis in 8,3%. Concha bullosa was observed in 33,3% of nasal cavities, nasal septal deviation (located in middle meatus) in 23,3% and Haller's cell in 9,3%. Conclusions: The most affected paranasal sinuses were: maxillary, ethmoid, sphenoid and frontal. Correlation between sinusitis and presence of Haller's cell, concha bullosa and nasal septal deviation (located in middle meatus) was not observed.
