<prompt> The nerve that supplies skin over the angle of mandible, if involved in parotid injuries forms a part of anatomical basis for gustatory sweating:Auriculotemporal nerveGreater auricular nerveZygomaticotemporal nerveBuccal nerve  <response>: b Greater auricular nerveRef. Cummings, 6th ed., 1254The nerve that supplies skin over the angle of mandible is Greater auricular Nerve. Sometimes during parotid surgeries, Greater auricular Nerve also gets injured along with the Auriculotemporal Nerve. In this situation with the aberrant regeneration of the Auriculotemporal Nerve, the parasympathetic fibres of the auriculotemporal nerve to salivary glands become aberrantly connected with the sympathetic cholinergic fibres to sweat glands of the skin overlying the parotid as well as overlying the angle of mandible the territory of Greater auricular nerve.
