Schwannomas in the middle ear and external auditory canal are exceedingly rare. The facial nerve, chorda tympani nerve, and Jacobson's nerve have rarely been reported as the origins of primary schwannomas in the middle ear cavity. We experienced a case of carotid sympathetic plexus (CSP) schwannoma that arose from the carotid canal and extended into the middle ear and external auditory canal. The tumor presented bone erosion of the carotid canal, and it adhered tightly to the internal carotid artery. This report represents the first documented case of a CSP schwannoma, which involved the middle ear and external auditory canal.
中耳和外耳道的施万细胞瘤极为罕见。面神经、鼓索神经和鼓室神经很少被报道为中耳腔内原发性施万细胞瘤的起源。我们遇到一例起源于颈动脉管并延伸至中耳和外耳道的颈交感神经丛（CSP）施万细胞瘤。肿瘤表现为颈动脉管骨质侵蚀，并紧密附着于颈内动脉。本报告是首例记录在案的累及中耳和外耳道的CSP施万细胞瘤病例。
