RESUMEN
OBJECTIVE: This study aimed to analyse the outcomes of surgery for pleomorphic adenoma of the parapharyngeal space in relation to the surgical approach. METHOD: This was a single-centre retrospective data analysis conducted from January 2008 to December 2020 on all patients who underwent operation for pleomorphic adenoma originating from the parapharyngeal space. RESULTS: Twenty-one patients with a mean age of 52.6 years were included. The transparotid-transcervical approach was the most common (52.4 per cent, n = 11) surgical approach, followed by transoral robotic surgery (28.6 per cent, n = 6) and conventional transoral surgery (19 per cent, n = 4). Post-operative complications included nine cases of transient partial facial nerve palsy and two cases of Frey's syndrome after the transparotid-transcervical approach and 2 cases of transient trismus and 1 pharyngeal wound dehiscence in the conventional transoral approach group. Complete macroscopic excision was always achieved, and no recurrence occurred during follow up. CONCLUSION: These three approaches can provide adequate tumour visualisation, a high rate of clear excisional margins and an acceptable morbidity.
