Introduction: Maxillary odontogenic myxoma is a locally invasive benign mesenchymal tumor. The objective of this case observation was to discuss the difficulties related to the management of a case of giant maxillary odontogenic myxoma. Observation: This was a 32-year-old patient who consulted in the stomatology and maxillofacial surgery department of the CHU-CNOS Pr HT of Bamako for a swelling of the left hemiface evolving for 3 years with deterioration of the general condition. She has no particular medical or surgical history. On physical examination, there was a large swelling of the left hemiface measuring 35/21cm, hard and painless to palpation. There was also exophthalmos of the left eye, filling of the left nasal fossa, left suborbital hypoesthesia, and ipsilateral submandibular adenopathy. A maxillofacial CT scan and operability assessment were performed. After intense renutrition, surgical excision was performed under general anesthesia with a primary tracheotomy. Histological examination of the surgical specimen concluded that it was an odontogenic myxoma. The outcome was favorable, there was no recurrence after 12 months. Conclusion: Odontogenic myxoma is a benign tumor with slow progression and can be locally invasive, making surgical management difficult.
