[Lingual-mandibular remodeling resection in prognathism].
The combination of --hypoplastic upper jaw, with narrow soft palate, --glossoptosis (or low, propulsive tongue), associated with protrusion of lower jaw, is well known. Early, exclusively orthopedic management combines enlargement of the superior arcade; functional/postural re-education of the tongue. Surgical management comes in later; it associates modeling resection of the tongue intended to position the tongue against the palate, with Chevron's mandibular resection, suppression of the first premolar, and salvaging the mental nerve. This type of osteotomy is indicated whenever a 6 to 8 mm mandibular retrusion is required. Fixation is monomaxillar, via extemporaneous splinting, associated with low external cortical osteosynthesis. The latter allows for gain of motor activity as early as the second day post-surgery.
