Carotid Body Tumor: Our Experience with 42 Patients and a Literature Review.

To review characteristics, signs, diagnostic methods, and surgical complications in patients with carotid body tumor, in addition to a literature review. This was a cross-sectional study carried out on 42 patients with carotid body tumors referred to Al-Zahra hospital of Isfahan from January 1, 2016, to December 31, 2019. The studied characteristics included age at the onset of symptoms, gender, symptoms, duration of symptomatic status before diagnosis, diagnostic methods, pathological outcome, tumor stage, and surgical complications. The collected data were analyzed using SPSS 21. In this study, 34 patients (80.96%) were female. The mean age at the onset of symptoms was 54.41 years. The mean duration of symptoms before diagnosis was 12.55 months. There was no significant difference between genders for the age and duration of symptoms before diagnosis (p > 0.05). Symptoms were mainly painless mass, hoarseness, coughing, earache, tinnitus, and headache. After surgery, two cases of permanent cranial nerve injuries were found. Thirty-nine patients (93%) were diagnosed by ultrasound imaging and CT scan. We had one case of arterial repair. There was one malignant and one functional tumor. According to the results, carotid body tumor is more common in females especially on the right side. Bilateral tumors are prevalent in females. This mass should be removed by surgery at the time of diagnosis in cases where the patient is not at high risk for surgery due to comorbidities, and the risk of complications following surgery is low.
