Abstract:

Objective   To investigate the effect of brain cotton technique in endoscopic middle meatus antrostomy for removing maxillary fungus ball. Methods   16 cases of maxillary fungusl balls were randomly divided into two groups: the brain cotton technique group and the nonbrain cotton technique group. The surgical time, post-operative complications and recurrence were compared between the two groups. Results   6 patients were enrolled in the brain cotton group and were performed operations from 40min to 60min with an average of 51min. Followed up by endoscopy in 12 months, no one had postoperative complications or recurrence. 10 patients were enrolled in the nonbrain cotton technique group, 5 of whom had inferior meatus antrostomy and were performed operations from 30min to 100min with an average of 74min. Followed up by endoscopy for 6 months to 20 months, no one had recurrence. 2 patients had nasal adhesion and were cured by endoscopy in outpatient. Conclusion   Maxillary fungus ball can be cured just through endoscopic middle meatus antrostomy assisted by the brain cotton technique. It is simple and convenient with little damage and good result and can be widely applied in clinic.
