Facial nerve paresis is a known complication to surgery in the facial region. Spontaneous regeneration of such injuries has been described, but little is known about the prognosis and optimal management. This is a case report of two patients with partial facial nerve paresis following surgery. The patients were treated conservatively. Both experienced a regeneration over ten months post-operatively. This suggests a favourable prognosis with conservative treatment in selected cases, which is reassuring for both doctors and patients.
