Análise da anatomia do recesso frontal em tomografia computorizada: Estudo de 50 doentes

Objective: Study the prevalence of frontal recess accessory cells in patients with indication for endonasal surgery. Study Design: Anatomical study of sinus CT scans. Material and Methods: Analysis of sinus CT scans from patients with indications for endonasal surgery. Exclusion criteria included previous surgery, complicated sinusitis and disease that unable structures identification. Results: 50 patients were included in the study with CT scans performed at diferent radiology centers. The prevalence of each cell was: Agger Nasi (92%), Frontoethmoidal cells type I (28%), type II (15%), type III (10%), Frontal Bulla (5,3%), Suprabullar cell (44,7%), Supraorbital cell(20%), Interfrontal septal cell (38%). Conclusions: The study describes the frontal recess pneumatization pattern in patients with nasosinusal symptoms. The results were similar with those found in other studies.
