Modified Parotidectomy for Benign Tumors of Parotid Gland

Objective: To review the advantages of a modified technique in the surgical treatment of superficial parotid gland benign tumors.Methods: 40 patients were randomly divided into two groups and retrospectively reviewed.In group A(n = 18),patients were treated by the modified operation including aesthetic incision,preserving great auricular nerve,partial resection of parotid and reconstructed by parotidomasseteric fascial flap.In group B(n=22),patients were treated by a conventional technique.All patients were assessed with their functions and complications postoperatively.Results: All patients were followed up from 12 to 24 months.In group A,none was found of temporary facial paralysis,visible scar and retromandibular depression,2 cases showed temporary ear lobe numbness,and 2 cases suffered from Frey's syndrome.In group B,7 cases showed ear lobe numbness,12 cases suffered from facial paralysis,and 14 cases suffered from Frey's syndrome.Conclusion: The procedure of the modified parotidectomy is simple and useful in avoiding injury of facial nerve and great auricular nerve,avoiding facial deformity and preventing Frey's syndrome postoperatively.The incision scar is concealed with satisfied aesthetic effect.
