Abstract
To analyse the anatomical characteristics of the marginal mandibular nerve with its impact on esthetic surgeries. Sources and methods: After the approval of the ethical committee 108 extratemporal facial nerves were dissected in the department of pathology. Intradissective observations, digital documentation, macroscopic and stereomicroscopic results of the removed specimens were analysed. Results: The characteristics of the examined nerves present an important difference of their course, diameter, branching patterns, collateral structures and vascularisation. Their rapport with other anatomical structures is not constant. Differences may occur regardless of the examined side, sex or age. Even when constant dissective conditions, unpredictible difficulties may occur. Conclusion: The anatomy of the marginal mandibular branch is inconstant. To avoid its damage, profound knowledge of the anatomy and meticulous surgery are musts.
