Background The incidence of nasolabial cysts is very low. Simple excision through a sublabial approach is the treatment of choice. The aim of this study was to evaluate the microdebrider as a tool in transnasal endoscopic marsupialization for nasolabial cysts and compare it with conventional instruments and a sublabial approach for cyst removal. Methods Retrospective chart review of 30 patients (31 cysts) with a mean age of 46.9 years received surgical treatments for nasolabial cysts. We performed three types of surgical procedures including the sublabial approach (10 cysts), conventional transnasal marsupialization (13 cysts), and microdebrider-assisted marsupialization (8 cysts). Results Patients that received surgery with the sublabial approach experienced significant increases in operation time, blood loss, and hospitalized time compared with those treated with transnasal marsupialization. However, the number of postoperative stoma stenoses was higher for conventional transnasal marsupialization (two cases). No recurrences or other postoperative complications were found during the follow-up. Conclusion The transnasal marsupialization of nasolabial cysts has remarkable benefits compared with sublabial cyst excision during operation. Microdebriders can be used safely and effectively in endoscopic marsupialization without stoma stenosis.

Drug inventory management is an important part of hospital management. The large amounts of drug data in hospitals bring challenges to optimizing the setting values for the safety stock and the maximum inventory of each drug. This study combined a two-stage clustering method with an inventory policy (s, S) and established a simulation optimization model for the case hospital’s outpatient pharmacy. This research used the simulation optimization software Arena OptQuest, developed by Rockwell Automation Inc. (Rockwell Automation, Coraopolis, PA, USA), in order to determine the minimum and maximum values (s, S) of the best stock amounts for each drug under the considerations of cost and related inventory constraints. The research results showed that the minimum and maximum inventory settings for each drug in the simulation model were better than those set by the case outpatient pharmacy system. The average inventory cost was reduced by 55%, while the average inventory volume was reduced by 68%. The proposed method can improve management efficiency and inventory costs of hospital pharmacies without affecting patient services and increasing the inventory turnover rate of the drugs.
