Facial paralysis is an unsatisfactory pathology to treat, and the results of neural reconstruction are unsatisfactory. Fortunately spontaneous recovery is common. We will talk about the new trends in the management of Facial nerve Paralysis, which not include its Diagnosis but also its Treatment in this article which we hope to be useful for patients and of course for E.N.T. Doctors or any Doctors concern with this subject. The aim of this study will be focused on new trends in diagnosis and treatment of lower motor facial nerve Paralysis. The primary use of gracilis free tissue transfer in the head and neck region is in the form of a muscular free flap for the dynamic rehabilitation of long-standing permanent facial paralysis. When combined with cross-facial nerve grafting or used as a single-stage reconstruction, free tissue transfer offers the best prospect for restoring spontaneous emotional facial expression. Benefits of this muscle over other free flaps used for dynamic facial reanimation include consistent anatomy with large caliber vessels, ease of harvest, a 2-team approach, reliability, and acceptable donor site morbidity. Drawbacks include excessive bulk, skin tethering, and a donor site scar that may be minimized with minimally invasive techniques. Secondary procedures to refine the results are often necessary to achieve a good final result. Ultimately, the choice of muscle for dynamic facial reanimation depends on the surgeon's experience and comfort level.
