Background: Carotid paragangliomas, or carotid body tumours (CBT), often present significant surgical challenges. The objective of this study was to examine the impact of a multidisciplinary surgical approach on carotid body tumour resection and clinical outcomes.

Methods: A retrospective review of all patients who underwent carotid body resection within the Calgary Health Region from January 1, 1994, to December 31, 2019 was conducted. Patient demographics, operation parameters, co-morbidity, post-operative complications and the usage of pre-operative embolization were compared using appropriate statistical methods. A p-value of < 0.05 was considered statistically significant.

Results: Of the 49 patients included in this study, 28 underwent resection by a single specialty and 21 underwent resection by a multidisciplinary team. The multidisciplinary team operated on significantly larger (p < 0.001) and more complex CBTs (p = 0.006). When analyzed as a group, operating time (p < 0.001) and length of hospital stay (p = 0.019) were significantly longer for patients operated on by the multidisciplinary team, reflecting the greater complexity of the CBTs in the multidisciplinary cohort. However, a sub-group analysis of high Shamblin grade tumours by surgical team showed no differences. Pre-operative embolization was performed in 41% of cases. There were no post-operative deaths.

Conclusions: Surgical management of CBTs can be challenging. However, we were unable to find any improvement in OR time, blood loss, length of hospital stays or complication rate in the multidisciplinary group. Pre-operative embolization did not significantly diminish intra-operative blood loss.
