Objectives

To conduct a prospective study investigating the causes of repeated recurrences of antrochoanal polyps (ACPs) in an attempt to minimize recurrence.

Materials and methods

Twenty-two patients, with an established diagnosis of a recurrent ACP, were included in the study. A subjective visual analogue scale, endoscopic examination, and computed tomography, both coronal and axial, were performed preoperatively. Endoscopic sinus surgery was performed in all cases, combined with transcanine antrostomy in some cases, aiming at the complete removal of the polyp. Postoperatively, improvements in clinical symptoms and endoscopic findings were evaluated using visual analogue scale and endoscopic examination.

Results

The study included 22 patients with recurrence of an ACP one to five times (a total of 38 previous surgeries). The endoscopic transnasal approach was used in 14 cases, whereas a combined endoscopic transcanine approach was used in eight cases. The success rate was 85.7% in the endoscopic transnasal approach and 100% in the combined endoscopic transcanine approach. All patients showed a subjective improvement after surgery but endoscopic recurrence was detected only in two cases after 18–24 months of follow-up.

Conclusion

The main cause of recurrence of ACPs is incomplete removal. Every effort should be made to completely remove the polyp (especially antral part) to avoid recurrence. Endoscopically, this can be performed using 30–45 and 70π telescopes, angled forceps, and performing a very wide middle meatal antrostomy and may be assisted with a canine fossa puncture. The operation preserves healthy antral mucosa and promotes epithelization and mucociliary clearance of the antrum.
