BACKGROUND AND OBJECTIVE: Extratemporal @entity2103 are rare. In the present study, the epidemiology, clinical presentation and in particular surgical treatment of this entity was analysed under special focus on facial nerve preservation. @entity1 /METHODS: 22 @entity1 with an extratemporal @entity2103 of the parotid gland, treated at the University-ENT-Clinic Hamburg-Eppendorf during 1977-1997 were analysed retrospectively. RESULTS: All @entity1 presented with a unilateral parotid mass, on ultrasound examination regularly an encapsulated @entity5 . 16 @entity1 (72.7%) had regular facial nerve functioning. 6 @entity1 (27.3%) with partial or complete peripheral @entity3541 were treated with partial or radical parotidectomy because of @entity5 possibility. In the group of @entity1 with intact facial nerve, latero-facial (superficial) parotidectomy with segmental nerve resection was undertaken in 9 cases (56.3%) because nerve-continuity was not siezable within the @entity5 area. In 7 cases (43.7%), @entity5 -enucleation was feasable with complete nerve preservation. Intraoperative frozen section in a total of 4 (18.2%) @entity1 always showed the correct histopathological diagnosis. No @entity5 -recurrence was observed in the 15 cases (68.6%) which underwent follow-up. CONCLUSIONS: In case of extratemporal @entity808 of the parotid gland, preparation of the facial nerve during surgery is often impossible, leading to segmental nerve resections. This decision, however, is made without proof for @entity5 . In recognition of the biological behaviour of this entity the authors recommend that after @entity5 exploration a biopsy should be taken from the periphery of the @entity5 to exclude @entity5 . After diagnosis of a @entity808 a nerve preserving (wait-and-see) approach appears justified.
