[Mandibular laterognathism and its treatment]

It is proposed to alter the classification of laterognathy due to excessive unilateral development of the mandible into hypercondyly and mandibular hemihypertrophy. Two forms are distinguished: those with occlusal modifications and those with conserved occlusal ratios and compensatory skeletal deformities usually involving the two stages. Treatment of laterognathy with occlusal deformity is usually by condylectomy--a simple operation with rapid results and excellent articular tolerance. Treatment of those forms with marked skeletal deformity is usually by condylectomy combined with a Lefort I of occlusal adaptation, surgery for the basilar border being difficult and aleatory except in the region of the chin.
