Non-conservative surgery in the parotid region results in a devastating complete facial paralysis (as with other causes of persistent facial palsy). Lengthening temporalis myoplasty is one of the available rehabilitating techniques. This is a series of 15 patients who had this procedure after a radical parotidectomy. Ninety-three percent had a good result at rest and 66.6% good result for smile. The authors recommend this type of surgery immediately after extirpation as it does not compromise the oncological field and improves the patient’s quality of life. It can be associated with additional measures to rehabilitate the upper face as well such as lengthening of the levator palpebris superioris or the implantation of a gold weight.
