Objective:The aim of this study is to explore the clinical value of V-shaped concealed incision in parotid benign tumors surgery.Method:Thirty-two patients with benign parotid tumors who were hospitalized from January 2016 to December 2017 were selected. All patients were treated with a V-shaped incision approach, starting from the anterior dermatoglyph of the tragus,extending downward to the earlobe and backward to the posterior earlobe, which formed an intersection point of the earlobe for parotid benign tumors,superficial lobectomy and facial nerve dissection.The greater auricular nerve and parotid masseter fascia were preserved,and the occult incision and prognosis were followed up for 1 year.Result:①All patients achieved primary healing without salivary fistula and infection.The visual analogue scale (VAS) score of 32 patients with postoperative aesthetic satisfaction was 0.②Of the 32 patients,only 2 had temporary facial paralysis after operation, which returned to normal after 1 and 2 months,while the rest had no facial paralysis symptoms.③The posterior and inferior auricular branches of the greater auricular nerve were preserved in all the 32 patients, and the sensation of the lobe was numb to varying degrees after the operation. After 3 months,the sensation recovered completely.④Two patients had skin flushing and sweating on the affected cheek during masticatory exercise, while the others had no Frey syndrome. ⑤Five patients who were repaired with sternocleidomastoid muscle flaps during operation were reexamined one year after operation.There was no significant asymmetric depression on the operative side compared with the healthy side.⑥All the 32 patients were followed up for 1 year without recurrence.Conclusion:The V-shaped concealed incision is performed for benign tumor resection of the parotid gland. The incision approach is concealed and the scar is not obvious.The surgical field is clear and easy to operate.It is not easy to damage the facial nerve and the ear nerve. After the operation,the patient has a satisfactory facial shape.The parotid gland secretion function is basically normal,which is superior to the traditional S-shaped incision and has good clinical application value.
