Abstract
Objective: A parotid gland tumor is an important disease for otolaryngologists to be able to treat through surgical technique in Japan. It is necessary to preserve facial nerves completely and to not make a prominent postoperative incisional scar of the skin, particularly in the case of benign tumors.
Method: We experienced 42 cases of parotid gland tumors in 2011. We tried to diagnose by CT scan, MRI imaging, and fine needle aspiration at preoperation.
Results: Benign tumors made up 37 cases, with the rest malignant tumors. We could identify a benign tumor in almost all cases at preoperation. In case of benign tumor, permanent facial nerve palsy was not found, except the schwwanoma in facial nerve at postoperation. Moreover, when we removed the tumor, the following steps were taken: 1) A skin incision was established with minimum length. 2) Incising the preauricular area, we drew a cutting line on the external auditory canal inside a tragus. 3) The sigmoid curve in the postauricular area was designed as gently as possible. The cervical incision line was drawn along the digastic muscle.
Conclusion: It is clear that during operations for the facial nerves, complete extraction of the tumors and minimum skin incision in the parotid gland tumor yield compatible results.
