[Approaches to antrochoanal polyps in adults: long-term comparative results]

This study aims to evaluate the long-term results of endoscopic sinus surgery and combined approach with Caldwell Luc procedure for the treatment of antrochoanal polyps.

Between January 2002 and December 2009, 41 patients (24 males, 17 females; mean age 34.7 years; range 14 to 78 years) were retrospectively analyzed. Patients were divided into two groups according to treatment modality: group 1 included 26 patients who underwent endoscopic sinus surgery alone and group 2 included 15 patients who underwent endoscopic sinus surgery in combination with Caldwell Luc procedure. Both groups were compared for recurrence and complication rate.

Seventeen of 41 patients were diagnosed with right-sided lesions, while 24 patients had left-sided lesions. Recurrence was seen in three patients, including two were in the group 1 and one was in the group 2. There was no statistically significantly difference between the groups in terms of recurrence and complication rate (p>0.05). Mean follow-up was 50.5 months (range 15 to 94 months).

Current approach for the treatment of antrochoanal polyps is endoscopic sinus surgery. However, combined approaches should be performed to avoid recurrences, unless removal of antral part of the antrochoanal polyp completely by endoscopic resection is possible. Selection of the combined techniques depends on the surgeon familiarity with the procedure and whether the patient is pediatric case. Combined approach with Caldwell Luc is a safe procedure in adults.
