Myxoma is relatively rare in the stomatognathic region. The patient was a 16-year-old boy with an odontogenic myxoma occupying almost the entire right maxillary sinus. A panoramic radiograph showed clinically significant alveolar bone resorption in the right maxilla and a divergence between the right upper lateral incisor and canine. A computed tomographic scan revealed a neoplastic lesion extending throughout the right maxillary sinus. The lesion had caused thinning of the anterior, posterior, and inner walls of the maxillary sinus. The tumorlike mass was diagnosed as an odontogenic myxoma on biopsy and was surgically excised with the patient under general anesthesia. Follow-up 14 months after tumor resection indicated a good prognosis with no signs of recurrence to date.
