Abstract
Objective:To explore the clinical effects, surgical procedure and indications of surgical treatment for benign lesions in maxillary sinus through modified prelacrimal duct recess approach. Method:All 21 patients in this study who diagnosed with benign lesions in maxillary sinus, received routine preoperational exam and underwent endoscopic maxillary sinus surgery through modified prelacrimal duct recess approach. Postoperatively patients received routine medical treatment, and regular follow-up for average 11.3 months(from 3 months to 16 months). Result:Among 21 patients, there were 9 cases diagnosed with maxillary sinus cyst, 6 cases diagnosed with maxillary sinus choanal polyps, and 5 cases diagnosed with maxillary sinus hemorrhagic and necrotic polyps, 1 case of maxillary sinus root cyst. During the operation, the roots of maxillary sinus cyst or polyps were found in anterior or inferior wall of maxillary sinus. All patients recovered very well without recurrence. Conclusion:Modified prelacrimal duct recess approach appears to be a safe and effective method to resect benign lesions in the maxillary sinus, especially when lesions involved in anterior and inferior wall of the maxillary sinus.
