Sumario: | AIM: This study aims to evaluate the outcome of patients with complete facial paralysis following surgery to cerebellopontine angle tumours or following traumatic petrous bone fractures after reanimation by hypoglossal-facial anastomosis as regards clinical improvement of facial asymmetry and facial muscle contractility as well as complications associated with hypoglossal-facial reanimation procedure. METHODS: This thesis included a prospective study to be carried out on 15 patients with unilateral complete lower motor neuron facial paralysis (11 patients after cerebellopontine angle tumour resection and 4 patients after traumatic transverse petrous bone fracture) operated upon by end to end hypoglossal-facial nerve anastomosis in Cairo university hospitals in the period between June 2015 and January 2017. RESULTS: At one year follow up the improvement of facial nerve functions were as follows: Three cases (20%) had improved to House Hrackmann grade II, eleven cases (73.33%) had improved to grade III, and one patient (6.66%) had improved to House Brackmann grade IV. CONCLUSION: Despite the various techniques in facial reanimation following facial nerve paralysis, the end to end hypoglossal-facial nerve anastomosis remains the gold standard procedure with satisfying results in cases of the viable distal facial stump and non-atrophic muscles. Early hypoglossal-facial anastomotic repair after acute facial nerve injury is associated with better long-term facial function outcomes and should be considered in the management algorithm. |
