| Popis: | Objective: Determine the frequency of the sinonasal mechanical anatomic variants by CT Scan. Patients and method: Six-month retrospective study concerning sinus CT scans in the registers of Teaching Hospitals’ Imaging Services of Lome and Kara (TOGO). It involves patients without distinction of sex, of over 15 years without anomaly that can lead to a modification of the normal anatomical configuration of the paranasal sinuses’ cavities. The analysis has been made by only one radiologist. Results: The frequency of mechanical sinonasal anatomic variants stood at 91.87%. The narrowing of the middle nasal turbinate was the variant mostly observed (55.03%), dominated by the deviation of the nasal septum whose frequency was 25.48%. The narrowing of the infundibulum represented 10.80% of population. They were more represented by the Haller cell which displayed a frequency of 3.60%. The variants venturing to narrow the upper nasal turbinate, represented only by extra turbinates, involved 1.02% of the population. The other variants of mechanical sinonasal anatomic variants represented 25.02%. They were dominated by the maxillary sinus septa (11.2%). Our study showed a feminine predominance which is statistically important for Haller cells (p = 0.037) and the ethmoidbulla hypertrophy (p = 0.0036). Conclusion: The anatomic variants of mechanical sinonasal are very frequent in Togo. |
