✦ Synopsis

The mandibular swing, or midline mandibular osteotomy with lateral mandibular displacement, provides excellent exposure equivalent to that obtained by composite resections of the mandible while minimizing cosmetic and functional disability and reducing the complexity of reconstruction. This procedure is most commonly described from an oncologic standpoint. Modifications of this procedure, performed on patients with adequate anterior mandibular height, provide access to lesions of the skull base, as well as benign lesions of the parapharyngeal space. Minor modifications of the midline mandibular osteotomy, as well as preservation of anterior mandibular dentition, provide these patients with immediate restitution of interocclusal anatomy and function. HEAD & NECK 1991;13:102-106 s p i r o described modifications of the mandibular swing with the mandibular osteotomy performed in the symphyseal area in a stepwise fashion so that the bone could be stabilized by direct wiring.' This direct wiring technique of a stepped osteotomy had an advantage over the straight bone cut as it decreased the risk of nonor mal-union at the osteotomy site. A potential restriction of this technique was that a stepped
