Abstract

Backgroud and Objectives: There are few reports about long-term outcomes of transnasal endoscopic marsupialization of isolated maxillary sinus mucocele. The approach routes of endoscopic marsupialization in those papers were mainly through middle meatal antrostomy. However, it is difficult or impossible to treat maxillary sinus mucocele by transnasal endoscopic middle meatal antrostomy in some cases. The aim of this study was to investigate long-term outcomes of transnasal endoscopic marsupialization according to three different approach routes.
Materials and Methods
We reviewed 20 consecutive patients underwent transnasal endoscopic marsupialization and followed up for at least 66 months, retrospectively. Ten patients were treated by transnasal endoscopic middle meatal antrostomy with marsupialization, four by inferior meatal antrostomy and six by extended middle meatal antrostomy.
RESULTS
No evidence of recurrence and major complications were observed during follow-up periods ranging from 66 to 102 months (mean, 80 months) according to three different approach routes.
CONCLUSION
Transnasal endoscopic marsupialization with the appropriate antrostomy route according to the location and bulging direction of maxillary sinus mucoceles is considered to be an effective therapeutic method with favorable long-term outcomes
