Outcomes of surgical treatment for carotid body tumor without preoperative embolization: a single-center retrospective study / 中华普通外科杂志

ABSTRACT

Objective:To investigate the outcomes of surgical treatment for carotid body tumor(CBT) without preoperative embolization at our institution.Methods:101 patients undergoing surgical treatment for CBT without preoperative embolization from 2011 to 2016 were followed-up for 2 years.Results:Complete resection of the CBT was achieved in all 101 cases(100%). Post-operative adverse events(AEs) mostly observed during hospitalization were as tongue bias(Ⅰ 4, 36.4%; Ⅱ 8, 19.5%; Ⅲ 13, 26.5%), hoarseness(Ⅰ 1, 9.1%; Ⅱ 4, 9.8%; Ⅲ 7, 14.3%), dysphagia (Ⅰ 0; Ⅱ 2, 4.9%; Ⅲ 7, 14.3%) and local hematoma(Ⅰ 0; Ⅱ 0; Ⅲ 1, 2.0%). No other serious AEs were observed. The total incidence of AEs was 5(45.5%) in type Ⅰ patients, 14(34.1%) in type Ⅱ, and 28(57.1%) in type Ⅲ. At the end of 2 years of follow-up, there was no AEs in type Ⅰ patients. The number of patients with adverse events in type Ⅲ was greater than that in type Ⅱ ( P>0.05). Three most frequently injured cranial nerves were hypoglossal nerve(21.9%), vagus nerve(20.3%), and recurrent laryngeal nerve(18.8%). Conclusion:Surgical management without preoperative embolization for CBT patients does not increase the risk of complications nor is it related to prognosis.
