CLINICAL-EVALUATION OF MAXILLARY DIFFUSE POLYPOID SINUSITIS AFTER FUNCTIONAL ENDOSCOPIC SINUS SURGERY

Functional endoscopic sinus surgery (FESS) for chronic sinusitis has b ecome popular as a substitution for radical operations. We selected 24 patients with diffuse polypoid rhinosinopathy who had been admitted f or FESS and followed up for at least 6 months. The recovery of 39 maxi llary sinuses was inspected with endoscopy through the enlarged middle meatal antrostomies. We found that of 8 sinuses recovered, 19 still h ad diffuse polypoid change, and another 12 had focal polypoid sinuses. We conclude that for diffuse polypoid rhinosinopathy, management of m axillary polypoid mucosa is complicated, and recovery of polypoid muco sa is dependent not only on the patency of the sinus ostia, but also o n other factors such as alterations of mucosal, glandular, and epithel ial changes by chronic stimuli.
