Thirty two patients; 18 males (56.25%) and 14 females (43.75%) were included with age range 12 to 43 years (mean= 25.6± 8.5). They were 14 developmental dentgerous cysts (43.75%) and 18 radicular cysts (56.25%); 20 on the left side (62.5%) and 12 on the right sides (37.5%) (table 1). The presenting symptom was slowly growing cheek swelling in all patients while only 6 patients (18.75%) complained also of facial pain and heaviness.
Complete cyst removal with its entire wall could be achieved in all cases without jeopardizing the maxillary sinus drainage through its natural ostium to the nasal cavity.
Recovery was event-less in all cases. Postoperative pain and facial swelling were mild in all cases and resolved within 7 days. Facial paresthesia, nasal obstruction, and hemorrhage were not detected. No tooth loss, infection or recurrence was reported throughout the follow up period that ranged between 2 and 6 years (mean= 4.7± 1.2). Throughout follow up period the teeth vitality was found sound, no nasal or paranasl persistence discharge, and normal nasal endoscopic examination.
In one patient (3%) with infected dentigerous cyst an oroantral fistula was reported 1 week postoperatively. It didn’t close spontaneously and it closed primary after curettage of the bone.
