A retrospective study on deep lobe tumor parotidectomy with preservation of the superficial lobe

Objective: To study our experiences on deep lobe tumor parotidectomy with preservation of the superficial lobe of the parotid gland.

Methods: Eleven cases of benign tumor in the deep lobe of the parotid gland were analyzed restrospectively. Tumour recurrence, Frey's syndrome, paralysis of facial nerve, salivary fistula, dry mouth and feeling around the auricular lobule were evaluated.

Results: Numbness around the auricular lobule appeared in 2 cases and salivary fistula appeared in 1 case, transient facial paralysis in 1 case. There were no patients appeared Frey's syndrome, dry mouth, permanent facial paralysis and recurrence in the 1-3 years followed up time.

Conclusions: Deep lobe tumor parotidectomy with preservation of the superficial lobe improves the cosmetics and the feeling around the auricular lobule, reduces the incidence rate of Frey's syndrome, facial paralysis and dry mouth.
