摘要：

BackgroundBecause the incidence of schwannoma arising from the parapharyngeal space (PPS) is very low, no studies have analyzed extirpation methods and postoperative neurological complications exclusively in PPS schwannomas. MethodsThe preoperative diagnosis and clinical outcomes of surgical treatment in 21 patients with PPS schwannoma who underwent surgery were investigated. ResultsNeurological deficit of the involved nerve developed in all patients regardless of the extirpation method used. However, the incidence of first bite syndrome in sympathetic chain schwannoma was significantly lower after intracapsular enucleation (40%) than after total resection (100%; P=.045). Furthermore, the incidence of postoperative complications unrelated to the involved nerve was lower after intracapsular enucleation (0%) than after total resection (42.9%; P=.055). ConclusionAlthough postoperative neurological deficit of the involved nerve was unavoidable in PPS schwannoma, intracapsular enucleation could be beneficial by reducing its severity and the incidence of complications unrelated to the involved nerve.
