Bilateral hypertrophy of the temporal muscle can give the impression of a harsh facial appearance that manifests itself as a morphopsychological conflict for the subject involved (Minotaur syndrome). This article describes a new facial aesthetic surgical procedure in the area of the temporal muscle. The author describes the surgical technique and the surgical instrument that he developed specifically for performing aesthetic contouring of the temporal area by reducing the muscle volume discrepancy ("myosuction"). The follow-up results of 11 cases demonstrated that this procedure renders valid results in the overall aesthetic reharmonization of the face and an improvement of individual psychological well-being.
