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.
施万细胞瘤是一种良性肿瘤，在头部较为常见，但鼻窦区域受累罕见，目前文献中仅报道了5例上颌骨施万细胞瘤，占骨肿瘤的比例不到1%。
我们报告了一例患有右上颌骨施万细胞瘤的女性患者，该患者接受了病变的完整切除。重点强调了该病变在位置方面的罕见性，并对其临床行为、诊断和当前治疗选择进行了综述。
如果出现模糊的鼻窦症状、鼻旁肿块或如本病例中的三叉神经痛，必须怀疑上颌三叉神经施万细胞瘤。建议进行手术治疗，手术方法根据位置和肿瘤大小而异。
