Transnasal inferior meatal antrostomy with a mucosal flap for post-Caldwell-Luc mucoceles in the maxillary sinus.

OBJECTIVE

Transnasal inferior meatal antrostomy is increasingly used for the treatment of post-Caldwell-Luc mucoceles in maxillary sinus. This study aimed to report the outcomes after inferior meatal antrostomy with a mucosal flap for recurrent mucoceles.

METHOD

The records of patients who had undergone transnasal inferior meatal antrostomy with or without a mucosal flap were reviewed.

RESULTS

Transnasal endoscopic inferior meatal antrostomy with or without a mucosal flap was performed in 21 and 49 patients, respectively. No complications were observed. A closing of the antrostomy was found in 9 (18.4 per cent) of the 49 patients who underwent antrostomy without a mucosal flap. No closings were observed in the 21 patients who underwent antrostomy with a mucosal flap. There was a significant difference in the rate of closing for surgery with and without the mucosal flap.

CONCLUSION

Transnasal endoscopic inferior meatal antrostomy with a mucosal flap is a safe method for the treatment of post-Caldwell-Luc maxillary mucoceles that effectively prevents recurrence.
