Clinical Study of Surgical Treatment for Carotid Body Tumor

Objective: To analyze retrospectively experience and lessons about diagnosis,surgical treatment and complications prevention of 27 cases of carotid body tumor(CBT).Methods: Analyzed and studied retrospectively 27 cases were treated by oral and maxillofacial head and neck surgery of Anhui Provincial Hospital from February 1990 to January 2010,and all patients were preoperatively confirmed by imaging(B ultrasonic,DSA and CTA).Using a carotid body tumor blunt dissection type resection for 11 cases,carotid body tumor and external carotid artery merger resection for 5 cases,carotid body tumor dissection type resection and internal carotid artery partial resection for 6 cases,and carotid body tumor dissection type resection and common carotid artery ligation for 5 cases.Results: All the cases were pathologically proved for carotid body tumor,and had no malignant transformation.No perioperative death happened,hemiplegia occured in 3 patients within 16-24h after surgery,3-4d improves gradually,and recovered to normal after respectively 16,22 and 47d.Muscle tension achieved above level.Except 1 cases died of stroke after two years,others are tumor-free survival by the average follow-up more than 5 years.Conclusion: We should confirm the diagnosis by preoperative selective imaging,and select the appropriate surgical program as soon as possible according to the relationship between the tumor and carotid artery.
