ABSTRACT

Introduction: The nasal cavities and paranasal sinuses have a complex anatomy and as a whole constitute a functional unit. Congenital anomalies and anatomical variants of this region are important, either because of their pathological consequences or because they can be a technical difficulty during surgery. Computed tomography has emerged as the method of choice for imaging paranasal sinuses. Objective: To analyze the anatomical variants of the uncinate process by computed tomography in patients with inflammatory, infectious and tumoral diseases, of nose and paranasal sinuses in a sample of Mexican population. Material and methods: A retrospective review of all the simple computerized tomographies of the nose and paranasal sinuses of patients in the Specialties Hospital «Dr. Bernardo Sepúlveda» National Medical Center 21st century from January 2016 to January 2017. Results: 139 patients were obtained from the database, of which 46 computed tomography studies were not found. The most frequent insertion was the middle turbinate with 68 cases (37.7%), with the left side predominating (52.9%). The most frequent pathology was inflammatory presenting in 53 cases (38.12%), predominantly chronic rhinosinusitis with polyps (23.02%) Conclusions: The most frequent insertion was the middle turbinate, unlike the lamina papyracea described in the international literature. The variation may be due to characteristics such as gender, race and other limitations of the study.
