technetium-tc-99m-sulfur-colloid and Maxillary-Sinusitis

Twenty-six maxillary sinuses (of 20 patients) were studied following Caldwell-Luc procedures. Surgery had been performed between 1 to 27 years previously. Follow-up studies included nasal endoscopy, coronal computed tomography and camera-sequence scintigraphy. Findings demonstrated that normalization of disturbed mucosal function was possible after surgery. Indications for revision endoscopic sinus surgery are discussed, as are the limitations of surgery.

The mucociliary clearance of the maxillary sinus mucosa was studied before and 6-18 months after functional sinus surgery using 99mTc-SC in 34 sinuses of 22 patients with chronic inflammation of the ethmoid and maxillary sinus. Before operation the mucociliary transport was very slow and sometimes absent. In the postoperative interval between 6 and 18 months we saw a significant return of the mucosal function. In 56% of the sinuses investigated the postoperative clearance rate was within the normal range. We also recorded a similar trend in allergic patients, although there was not such a clear return to normal of the mucociliary clearance, and the rates were not within the normal range. We found no recovery of the mucociliary function in 11 sinuses of 7 patients with impaired healing. Decisions on subsequent treatment were based on postoperative nasal endoscopy and functional mucosal repair.
