OBJECTIVES: To determine the usefulness of the @entity8021 time (ST) test for evaluating the mucociliary function of the maxillary sinus after endoscopic sinus surgery (ESS) for chronic @entity1244 . STUDY DESIGN:                 <AbstractText Label="METHODS" NlmCategory="METHODS">This study was conducted on 88 maxillary sinuses of 74 @entity1 after ESS. The maxillary sinus fontanel was broadly opened via the middle meatus using an endoscope, and a @entity8021 granule was adhered to the bottom of the maxillary sinus mucosa The time until the @entity1 recognized the sweet taste was recorded. Before the ST test, the bilateral maxillary sinuses were classified into the following four groups on the basis of the post-ESS severity of @entity4 and @entity4 as revealed by endoscopic observation: normal (45 sinuses), mild @entity4 and @entity4 (24), moderate mucosal finding (14), and severe mucosal finding or filling of the sinus with a polyp(s) (5). RESULTS: The mean ST values in the normal group and the groups with mild, moderate, and severe @entity4 and @entity4 were 35.7, 38.1, 63.6, and 88.0 minutes, respectively. Thus the ST increased with the post-ESS severity of the @entity3137 . However, for the group with mild @entity4 and @entity4 , scanning electron microscopic observation of three maxillary sinuses in which the ST exceeded 120 minutes and four sinuses in which the ST was 40 minutes revealed extensive cilia loss in the former sinuses, but not in the latter. A second post-ESS endoscopic observation was performed in 17 @entity1 , revealing improvement in 11 sinuses, no change in 5 sinuses, and aggravation in 1 sinus (compared with the initial test). The ST test was also repeated, revealing that the ST became shorter in most of the endoscopically improved sinus group. However, a few sinuses showed a discrepancy between the change in the endoscopic findings and the ciliary function (ST). CONCLUSION: Measurement of the maxillary sinus ST is a simple, accurate, and useful technique for assessing the post-ESS mucociliary function in conjunction with endoscopy, and the information gained can help in deciding subsequent therapy.
