A 6-year-old girl was admitted to Plastic Reconstructive and Aesthetic Surgery Clinic at Mangusada Hospital Bali with facial asymmetry on her right cheek, noticed since the past one week. She got some medicines from the general physician, but there was no improvement. From the CT scan, we found a solitary mass on the size of 3 x 3.2 x 3.6 cm on the right maxillary area. Enucleation was done and the Caldwell-Luc approach was performed under general anesthesia. The cyst revealed to have an ectopic maxillary canine inside. The cyst and ectopic tooth were extracted from the pathological site and the incisional specimens were sent for histopathological examination. The result revealed a cyst lined by non-keratinized stratified squamous epithelium without any malignancy. She had antibiotics therapy post-surgery, and her symptoms were resolved within a week.
