Impact of Manual Lymphatic Drainage on Postoperative Edema of the Face and the Neck After Orthognathic Surgery

Overview

Orthognathic surgery aims to standardize position of the maxilla and the mandible and therefore chewing, breathing, phonation and swallowing functions. In postoperative, several physical and functional consequences are observed in patients: transient edema of the face, maxillo-mandibular blocking (causing difficulties to eat and occasional weight loss), pain and sensory disturbances (labial or/and chin paresthesias). Achieving sessions of manual lymphatic drainage by physiotherapist may allow faster decrease of postoperative edema, improved postoperative comfort and mental well-being. The main objective of this study is to evaluate the efficacy of sessions of manual lymphatic drainage to reduce postoperative edema.

The main objective of this study is to evaluate the efficacy of sessions of manual lymphatic drainage to reduce postoperative edema. Secondary objectives of the study are to assess impact of sessions of manual lymphatic drainage on patient comfort (pain, aesthetic discomfort, difficulty in breathing and discomfort in swallowing) and on ental well-being. Patients allocated to the intervention group will have 13 sessions of manual lymphatic drainage and those allocated in control group will not. Edema of patients will be measured at day 1, day 8, day 15 and day 22 after surgery by a different physiotherapist than physiotherapist achieving drainage sessions, blind to the randomization group of the patient. At the same time, comfort criteria will be assessed by a visual analogue scale and mental well-being with the General Health Questionnaire (GHQ28).
