Odontogenic myxoma involving the right nasal cavity, orbital floor, and skull base in a 20-year-old woman: Removal and review of the literature

Odontogenic myxoma (OM) is a rare benign tumor in the jaws. It is considered locally aggressive but non-metastatic. Here, we report a case of Odontogenic myxoma observed at a relatively rare site, which occurs in the maxillary posterior interdental region and maxillary sinus, as well as involves the right nasal cavity, orbital floor, and skull base. A 20-year-old young female patient was referred to institution for right-sided nasal congestion and facial swelling. The right inferior nasal tract and common nasal tract of the patient were blocked with a reddish neoplasm. The clinical history and preoperative examination and iconography findings were indicative of an odontogenic cyst. The patient received Right-sided nasal sinus tumor resection via end nasal endoscopic anterior lacrimal saphenous fossa combined with Kollu's approach. The postoperative pathological findings were suggestive of an Odontogenic myxoma. Conservative surgical treatment is less surgically invasive, more acceptable to patients, and results in a better quality of survival.
