Abstract
Objective: Management of maxillary odontogenic cysts consists of transoral resection or curettage. Large lesions require extensive dissection, leading to perioperative morbidity and need for extensive reconstruction. 1) Describe the use of transnasal endoscopic marsupialization for the management of maxillary odontogenic cysts. 2) Understanding this approach can minimize morbidity with effective treatment.
Method: Case series. Endoscopic sinus surgical techniques were used to treat large benign maxillary odontogenic cysts in five patients between June 2008 and October 2011.
Results: Patients underwent endoscopic marsupialization after creation of a wide maxillary antrostomy. Molars associated with the cystic lesions were displaced into portions of the maxillary sinus in 2 cases. The molars were dissected and removed through the transnasal dissection in each of these cases. Histological and radiological findings were consistent with 1 odontogenic keratocyst, 3 dentigerous cysts, and 1 radicular cyst. The lesions were able to be marsupialized endoscopically with relief of the patient’s initial symptoms and no recurrence. Follow-up has shown an excellent functional outcome in all cases.
Conclusion: Benign maxillary odontogenic cysts can be effectively treated using transnasal endoscopic approaches. The techniques are less invasive and can reduce morbidity compared to transoral techniques.
