ABSTRACT
Variations of nerve are not only of anatomic and embryological interest but also of clinical importance. Theiradequate knowledge certainly help in increasing surgical precision and decreasing morbidity. In present studyvariations in mode of origin and level of formation of nerve to medial and lateral head of gastrocnemius wasstudied. The material for the present study comprised of 60 lower extremities belonging to 30 adult humancadavers obtained from Department of Anatomy, PIMS, Jalandhar. Neurectomy of nerve to medial gastrocnemiusmuscle is used to reduce volume of the muscle. For facial reconstruction after total parotidectomy, the facialnerve is being reconstructed by using vascularized sural nerve with free lateral gastrocnemius muscle flap
