BACKGROUND: It is well documented that @entity1179 ( @entity1179 ) have a localized attachment site. Still, instead of concentrating on the attachment site, endoscopic surgeons often perform an extended resection similar to the one achieved after external surgery. OBJECTIVE: Our objective was to evaluate an attachment-oriented endoscopic surgical strategy and to determine @entity1179 attachment diameter and location. METHODS: A prospective study was conducted. Thirty-three consecutive @entity1 who underwent endoscopic @entity1179 excision (2001--2007) were enrolled. Thirty @entity1 had adequate follow-up. Attachment diameters were measured in 25/33 @entity1 . Surgery included debulking, identifying the precise mucosal attachment site, subperiosteal dissection and excision of the attachment, frozen section control, and resection/drilling of underlying bone. RESULTS: The mean measured attachment diameter (n = 25) was 8.4 +/- 6 mm (range, 3-23 mm). Attachment locations included maxillary sinus (39%), ethmoid sinus (21%), nasal cavity (21%), frontal sinus (6%), sphenoid sinus (6%), lamina papyracea (3%), and cribriform plate (3%). The mean follow-up (n = 30) was 40 +/- 21 months. Three @entity1 had Krouse stage 1, 10 @entity1 had stage 2, and 17 @entity1 had stage 3. Nine @entity1 had undergone previous surgeries. After attachment-oriented endoscopic surgery, three @entity1 had persistent disease. @entity850 was the only complication (n = 1). CONCLUSION: Even advanced @entity1179 have small attachments. Their Identification facilitates efficacious resection with minimal morbidity.
