Abstract

OBJECTIVES: To assess the frequency of frontal sinus aplasia using computed tomography (CT) of the paranasal sinus among Saudi Arabian population. METHODS: A retrospective case review of medical records from January 2019 to December 2019 in the Otorhinolaryngology Department, King Abdulaziz University, Riyadh, Saudi Arabia. RESULTS: A total of 449 cases were reviewed. The incidence of bilateral frontal sinus aplasia was 3.3%. The incidence of right sinus agenesis was 5.12% and left was 1.33%. The mean age of reviewed patients was 39.15 years. CONCLUSION: The frequency of frontal sinus aplasia is low; however, this must be considered before surgical operations related to the sinuses.
