Speech characteristics of 20 patients who underwent orthognathic surgery for correction of various skeletal defects were studied before surgical treatment and at periodic intervals postoperatively. Patients completed questionnaires that focused on their perceptions of appearance and oral function after orthognathic surgery. Approximately 60% of the patients demonstrated preoperative articulation errors. These were classified as mild because they did not interfere with the ability to be understood. Periodic testing indicated positive changes in articulation for a majority of those who had exhibited preoperative errors. None of the subjects experienced postoperative deterioration in their articulation. The subjects' perceptions of their individual operations were positive on all variables assessed.

Synchronized electromyography (EMG) and videofluorography were used to relate the EMG activity from the suprahyoid and masseter muscles and the movement of the hyoid bone to different phases of the jaw open-close-clench cycle. The subjects investigated comprised 19 adult males with normal dentofacial appearances. Five subjects were excluded from the analyses because of a uniform suprahyoid EMG pattern during cyclic jaw movements. The results from the remaining fourteen subjects revealed that mandibular opening was preceded by suprahyoid EMG activity and movement of the hyoid bone in an upward-forward direction. During jaw opening and the first half of the jaw-open phase, EMG activity was registered exclusively from the suprahyoid muscles. The hyoid bone was moved downward-backward during jaw opening. Mandibular closing was preceded by masseter EMG activity and movement of the hyoid bone in a further downward-backward direction. During jaw closing the hyoid bone moved upward and forward. Discrete EMG bursts from the suprahyoid muscles were occasionally registered simultaneously with the masseter EMG activity during jaw closing. No absolute reciprocity existed between suprahyoid and masseter muscle activity during cyclic jaw movements. A period of no EMG activity from either the suprahyoid muscle group or the masseter muscle was noted during the jaw-open phase and the occlusal phase.
