Transnasal endoscopic marsupialization for treatment of maxillary cysts / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To evaluate the effectiveness and usefulness of transnasal endoscopic surgery for the treatment of maxillary cysts.@*METHOD@#Transnasal endoscopic surgery was performed in 13 patients with maxillary cysts that extended to the maxillary sinus or the nasal bottom. Five patients had a radicular cyst, three patients had a dentigerous cyst, three patients had a nasolabial cyst and two patients had a median cyst. After the resection of anterior edge of the inferior turbinate or the nasal bottom, the lateral wall of the inferior nasal meatus was opened. Then, the cyst wall of the maxillary sinus was partially or completely removed under the endoscope.@*RESULT@#The cyst walls were completely or partial removed in 13 patients with maxillary cysts. There were no complications, and postoperative courses were uneventful. The follow-up period ranged from 6 to 36 months, and no recurrence were noted in any of the cases.@*CONCLUSION@#Endoscopic transnasal surgery for the maxillary cyst is less invasive than conventional dental approach, and most of the affected teeth can be preserved. This technique appears to be a simple and highly effective surgical treatment for the treatment of patients with maxillary cysts that extend to the maxillary sinus or the nasal bottom.
