[Clinical characteristics and surgical management in patients with third and fourth branchial anomalies]

Objective:To analysize the clinical characteristics as well as the effect and methods of the surgical treatment in patiets with the third and fourth branchial anomalies.Method:The clinical data of 25 patients diagnosed as third and fourth branchial cleft fistula by pathological method were analyzed retrospectively.Two of 25 patients had undergone fistulectomy simply.Based on the embryologicc and anatomic features of branchial anomalies,23 of 25 patients had received different types of selective neck dissection.All of lesions were confirmed as branchial cleft fistula by pathology.All patients were received the examinations of Esophagus myelography,MRI and CT preoperatively.Result:The features of the third and the fourth bianchial fistula were as following:most patients suffered from recurrent neck abscess and had undergone incision and drainage. Esophagus myelography and CT were important auxiliary examination for branchial anomalies.No recurrent and complications were found in all patients by using treatment of selective neck dissection (23/25 cases) and fistulectomy simply(2/25 cases) within 12 to 36 months following-up,postoperatively.Conclusion:Branchial anomalies is characterized by recurrent acute abscess,acute thyroiditis or fistula secretion inferior to neck.Complete removal of branchial lesions and inflammatory granuloma using selective neck dissection is a safty and effective treatment for recurrent branchial anomalies.
