Abstract
maxillary cysts of dental origin are not common diagnosis. There is still debate about their perfect treatment method. There are many approaches to manage the odontogenic maxillary cysts; either intraoral, sublabial, or transnasal endoscopic approach. In this study, we present our technique of trans-antral endoscopic assisted excision of maxillary cysts of dental origin with assessing feasibility, results, and complications. Thirty-two patients were reported; 14 dentigerous cysts (43.75%) and 18 dental (radicular) cysts (56.25%). Complete cyst removal could be achieved in all cases without jeopardizing the maxillary sinus drainage through its natural ostium to the nasal cavity. Postoperative pain and facial swelling were mild in all cases and resolved within few days. No tooth loss, Sino nasal symptoms, infection or recurrence was reported throughout follow-up period ranging from 2 to 6years. Trans-antral endoscopic assisted approach for excision of odontogenic maxillary cyst is a reliable, safe, and effective procedure without recurrence, or permanent negative sequels over the long-term follow-up.
