Palato-Antral Involvement of a Primary Extracranial Sinonasal Meningioma.

Primary extracranial sinonasal meningiomas are one of the rarest tumours involving the head and neck region. Very few reports exist with additional involvement of the palato-antral region. A 45-year-old male presented with frequent episodes of epistaxis, complaints of nasal blockage and nasal regurgitation for 8 months in 2021 at our tertiary care government hospital in East Godavari district, India. The patient was diagnosed with a primary extracranial sinonasal meningioma with palatal involvement and surgical excision via intra-oral and endoscopic approaches were performed. Postoperative healing was uneventful with no recurrence noted over 2 years. A palatal obturator was used for rehabilitation. The diagnosis of this pathology requires additional immunohistochemistry testing for confirmation and treatment entails complete surgical excision which assures no recurrence or delayed presentation of residual disease in follow-up.
