Clinical Evaluation of Maxillary Diffuse Polypoid Sinusitis after Functional Endoscopic Sinus Surgery

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