Maxillary trigeminal schwannoma. Presentation of a case and review of literature

Schwannomas are benign tumours that are relatively common in the head, however the involvement of the sinunasal region is rare and there are only 5 cases reported in the maxilla in current literature, representing less than 1% of bone tumours. We report the case of a woman with a right maxillary sch...

Description
Summary:Schwannomas are benign tumours that are relatively common in the head, however the involvement of the sinunasal region is rare and there are only 5 cases reported in the maxilla in current literature, representing less than 1% of bone tumours. We report the case of a woman with a right maxillary schwannoma who underwent a complete resection of the lesion. Emphasis is placed on the rarity of the lesion in terms of its location and includes a review of clinical behaviour, diagnosis and current treatment options. Maxillary trigeminal schwannoma must be suspected if vague sinunasal symptoms, paranasal mass or, as in this case, trigeminal neuralgia present. Surgical treatment is indicated, and approaches vary according to location and tumour size.
