Association of Antrochoanal Polyps with Contralateral Site Sinus Obliteration

Objective: The present study was performed to investigate the association of antrochoanal polyps (ACP) with contralateral sinus obliteration and their effect on recurrence.

Material and Methods: This retrospective study was performed by searching the records of 106 patients who underwent surgery with a diagnosis of ACP between January 2010 and January 2018. Determination of the presence of sinus obliteration in patients and scoring were performed by analyzing the preoperative paranasal sinus tomography. The Lund–MacKay (LMK) system was used for scoring. Patients were followed up for an average of 25 months (range, 12 to 47 months).

Results: Sinus obliteration was determined by examination of tomography results and the mean preoperative LMK score of 106 patients was 7.49±3.76. The mean LMK score for the side with the polyp(s) (5.49±2.56) was significantly higher than that of the contralateral side (2. 00±2.31) (p = 0.0001). Recurrence was detected in eleven patients (10.4%). The mean preoperative LMK score for the side with the polyp(s) of recurrence (+) patients was significantly higher than that of recurrence (–) patients (p = 0.039). There was no significant difference between mean LMK scores of the sides without ACP in recurrence (–) and recurrence (+) patients (p= 0.367). The total mean preoperative LMK score of recurrence (+) patients was significantly higher than that of recurrence (–) patients (p = 0.049)

Conclusion: In our study, it was observed that recurrencies increased in patients with ACP where sinus opacity was more intense, but contralateral sinus opacity had no effect on recurrence.
