technetium-tc-99m-sulfur-colloid and Ciliary-Motility-Disorders

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.

After reviewing the main methods existing to calculate the rate of the mucociliary transport, the authors describe their personal technique. A 99mTechnetium Sulphur Colloid drop is deposited in the nasal fossa, which is carried away by the cilia down to the rhinopharynx and followed by a gamma camera. To calculate the transport rate, a new method of quantification has been introduced, based on the formation of a parametric image. A study was carried out in 14 males without any pathology of the upper airways, obtaining a mean velocity of 5.3 mm per min (range 3.3.-8.2).
