Introduction:
Osteoma is the most common benign tumor of the nose and paranasal sinuses. It is a slow-growing bony tumor, often asymptomatic, occurring mainly in frontal and ethmoid sinuses. Theories regarding the origin of osteomas are still discussed. The aims of the study were to describe diagnosis circumstances in our series and to set out our respective indications for open and endoscopic approaches in the treatment of nasosinusal osteomas.
Patients And Methods:
A retrospective study was conducted on the files of all the patients treated for a paranasal sinus osteoma in our department between 1990 and 2013. Diagnosis circumstances and kind of treatment were collected and analyzed.
Results:
The files of 45 patients (mean age: 49.2; sex-ratio: 1.19) could be collected. The most common symptom was headache found in all patients. The most common location was the frontal sinus (30 cases). Thirty-nine open procedures were performed. Four osteomas were removed under endoscopic assistance. In one case, a combined approach has been used. Overall complication rate was 11.1%. Symptoms improved in all patients. Two recurrences were observed.
Discussion:
Surgical indications in paranasal sinus osteomas are theorically well codified. However, approaches remain controversial. In our experience, the preferred approach was the open one. Endoscopic techniques, when indicated, are more challenging and need sophisticated instrumentation and a long learning curve.
