The intervention consisted of performing conventional marsupialization of the odontogenic cyst followed by the novel placement of a ventilation Grommet tube to maintain long-term patency of the surgical window. After administration of local anesthesia, a small bony window was created over the thinnest cortical area of the cyst to expose the cystic cavity. The cyst lining was incised then the tube was placed

Cyst volume will be measured using CBCT and 3D Slicer segmentation at baseline and 6 months after marsupialization. Percentage reduction in cyst size will be calculated.

Patient satisfaction will be assessed using a validated questionnaire (e.g., 3-point Likert scale) at 6 months.

The presence of postoperative complications (infection, device displacement, or soft tissue overgrowth) will be recorded clinically at follow-up visits.
