OBJECTIVE: The current study aimed to analyze the clinical characteristics, diagnosis, and surgical outcomes of intraparotid facial nerve schwannoma (IPFNS) and propose a more definitive therapeutic algorithm for IPFNS. METHODS: Between January 2018 and December 2023, all the cases of IPFNS at our single institution were retrospectively reviewed. RESULTS: In total, 70 patients were included in this study. Among them, 23 (32.3%) were men and 47 (67.7%) were women. The patients commonly presented with a painless parotid mass, and three patients complained of facial paralysis. Magnetic resonance imaging (MRI) had the highest diagnostic efficacy (37.1%) among all the evaluation techniques used. Marchioni's classification and surgical method were significantly associated with postoperative facial function. In terms of surgical interventions, stripping surgery was suitable for type A tumors, while for types B, C, and D tumors, intracapsular enucleation with a microscope was recommended to decrease the influence of the procedure on facial nerve function. CONCLUSIONS: IPFNS is a rare disease, whose diagnosis and management remain challenging. MRI is the preferred preoperative diagnostic method. Preoperative facial nerve function, tumor location, and patients' preferences are key factors in the decision-making process of IPFNS treatment.
