Abstract:

A case of vagal schwannoma involving the parapharynx was reported to be surgically removed via the neck approach. The patient came to the clinic because of a huge mass on the left side of the neck with obvious choking. Doppler ultrasound, CT, and MRI suggested a schwannoma, and it may be originated from the vagus nerve. During the operation, the tumor was seen to grow eccentrically along the longitudinal axis of the vagus nerve, and the outer perineum was peeled off, layer by layer, along the non-recurrent larynx side of the tumor with blunt dissection. The tumor was completely separated and the outer perineum was peeled off gently. The perineum was closed after the tumor was completely separated. Pathologically, the diagnosis was schwannoma. The patient developed hoarseness and coughing after the operation. After symptomatic medication, the symptoms disappeared after six months of follow-up. No tumor recurrence was found. Indirect laryngoscopy indicated that vocal cord fixation was significantly improved.
