[Mucociliary clearance of radically operated maxillary sinuses and effect of endoscopic ethmoid bone revision on the mucociliary system]

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.
