Abstract

Background: The edematous mucosa of the maxillary sinus can give rise to benign lesions called antrochoanal polyps (ACPs), which can then expand into the choana.

Aim and objectives: In order to evaluate whether there is a correlation between the anatomical alterations seen in paranasal sinus computed tomography scans of normal subjects and those of patients with antrochoanal polyps.

Patients and methods: This prospective case-control study was performed on 90 patients from an outpatient clinic of Al-Azhar University Hospitals and Nasser Institute Hospital. Someone visited our facility for a PNS CT scan during the years 2022 and 2023. patients were divided into two groups.

Results: There was statistically significant variance among cases control regarding the incidence of Septal deviation P<0.001, Retention cyst in the contralateral maxillary sinus and Hypertrophied turbinate (p-value < 0.05). Non-statistically significant variation was observed among cases and control concerning unilateral and bilateral concha bullosa p= (0.18, 0.36, 0.023), respectively. There was statistically significant variance among cases and control (p-value < 0.05) regarding unilateral nasal obstruction and snoring, as about 53% of cases had unilateral nasal obstruction compared to 11% in controls. Also, 26% of cases involved snoring, compared to 8% in the control group.

Conclusion: The most frequent anatomical variation that occurs in patients with antrochoanal polyps is septal deviation. The second most common anatomical variation in patients with antrochoanal polyps was unilateral concha bullosa.
