%X <B>OBJECTIVE: </B>The primary objective of this study was to explore the potential disparity in postoperative fistula occurrence rates between patients who undergo (partial) lateral parotidectomy and those who undergo the extracapsular dissection technique for the management of benign parotid gland tumours.<BR><B>METHODS: </B>A consecutive series of 363 patients treated with (partial) lateral parotidectomy and extracapsular dissection technique for benign parotid gland tumours at one tertiary centre between 2018 and 2022 were included. To evaluate the impact of the surgical technique and possible other risk factors (tumour location, tumour size, Body Mass Index, age, smoking, diabetes mellitus, arterial hypertension) for the development of fistulas, multivariate logistic regression analyses using backward lection were applied to estimate odds ratios (ORs) and 95%-confidence intervals (CIs).<BR><B>RESULTS: </B>In 363 patients, 21 patients (5.8%) developed a fistula. Patients who underwent (partial) lateral parotidectomy had three times higher chance of developing a fistula compared to patients who were operated using the extracapsular dissection technique (ORadjusted = 2.6, 4.1% vs. 12.5%, p = 0.044). In the multivariate analyses, no other risk factors for the development of fistulas were statistically significant in this cohort. The incidence of facial nerve paralysis was not significantly different between the extracapsular dissection and lateral parotidectomy group (5/73 = 6.8% vs. 11/290 = 3.8%, p = 0.333).<BR><B>CONCLUSIONS: </B>Fistulas occur more often in patients treated by means of a (partial) lateral parotidectomy approach compared to patients treated using the extracapsular dissection technique. Therefore, surgeons should be vigilant about postoperative fistula risks in lateral parotidectomy and consider preventive measures.
