[Anatomy of marginal mandibular branch of facial nerve in partial parotidectomy].

OBJECTIVE

To study our experiences in anatomy of marginal mandibular branch of facial never in partial parotidectomy.

METHOD

Thirty-eight cases receiving partial parotidectomy were analyzed retrospectively, and marginal mandibular branch of facial nerve were separated in all cases.

RESULT

Temporary facial paralysis appeared in 2 cases and Frey's syndrome appeared in 2 cases. There was no patient appeared the recurrence in the 1-3 years followed up time.

CONCLUSION

Partial parotidectomy with anatomy of marginal mandibular branch of facial nerve is a safe, effective and minimally invasive therapeutic method for benign tumor on parotid gland (<5 cm).
