RESUMO
Facial nerve palsy can occur due to several causes and accordingly, several treatments have been proposed by plastic surgeons. This study is to determine the efficacy of temporal myoplasty in correcting the facial deformity of patients suffering from hemi-facial palsy whom were referred to "15 Khordad" hospital between 1381- 1385. Participants were 6 patients with hemi-facial palsy who referred continuously and were neither candidated for microscopic surgery, nor can tolerate free muscle transposition surgery. We conducted a clinical case study to compare pre and post-operation stages. In these patients, the new one-stage method of temporal tendon transposition to lip's commissure [without any grafting] was performed. They were followed for an average of 2 years. Assessments were made in terms of their age, sex, facial palsy cause, palsy duration, complications, and lip's commissure range of motion. Pre and post-operation photos were taken and physical examination was documented and analyzed for each case. Two cases [out of six ones] were men and the others were women. Their age range was 38.2 +/- 14 years old. In three cases, facial palsy was a post-traumatic result. One patient had congenital form. In another one it was due to tumor resection complications. The last patient was a tympanoplasty case. Palsy duration range was 28.7 +/- 11 months. No complication was seen after the operation. In early post-operation stage, 50% of patients had good static facial position and in remained 50% the result was excellent. However, in delayed stages, the percentages for excellent, good and moderate outcomes were 66, 17 and 17, respectively. Despite the well dynamic facial position in early post-operation stages among all the cases, in delayed stages the percentages for excellent, good and moderate results were reduced to 50, 33 and 17, respectively. It seems that for those who can not tolerate long operations nor like to do so, temporal myoplasty might be an acceptable method as an alternative for the standard surgical methods applied for hemi-facial palsy [i.e. the microscopy procedure]. It is recommended to conduct an absolute experimental study in this regard
