[The shortening of the ascending ramus of the mandible in a case of Class III malocclusion with open bite]. / Raccourcissement de la branche montante de la mandibule dans un cas de classe III avec béance.

With reference to a case reported here, the authors emphasize the importance of reducing the length of the ramus of the jaw in rather exceptional forms of gaps between the upper and lower jaws with an increase in the posterior height of the face. This procedure provides more stable results and the patient's gums are no longer revealed when smiling.

[Köle's operation]. / L'opération de Köle.

Kole's operation combines segmental alveolar osteotomy of lower incisor-canine region with a reduction mentoplasty. The procedure usually provides a reduction in height of mentum, sometimes with an advancement, and involves ablation of an intermediate bone fragment. Ablation of lower border as described by Kole too frequently results in an esthetically poor chin. Insertions of platysma and digastric muscles are untouched. The inferior segmental osteotomy separates the lower incisor-canine region, which is displaced upwards or upwards and backwards after extraction of premolars, displacement being maintained by interposition of bone detached during mentoplasty. A reduction glossectomy is almost constantly associated. The best indication for Kole's operation is anterior gaps with or without proalveoli. It is often combined with segmental or total surgery to maxilla. Results are generally stable, especially after mentoplasty, but from the dental aspect pulp mortifications are not rare.

[One-stage surgical treatment of temporo-mandibular ankylosis and its facial deformity]. / Traitement chirurgical en un temps d'une ankylose temporo-mandibulaire et de sa déformation faciale.

A patient with temporomandibular ankylosis was treated by resection of the ankylosed block followed by lengthening of the ascending ramus by an endoprosthesis. The place of the latter in the treatment of such lesions and the deformities that result from them is analyzed. Emphasis is laid on the value of displacement of the superior arch by a Le Fort I osteotomy in the correction of facial asymmetry in cases of laterognathia due to a mandibular development defect.

[The dangers of Trauner's operation]. / Les écueils de l'opération de Trauner.

The technique described by Trauner for using retro-condylar cartilaginous implants is outlined, and the complications observed indicated. External or inferior luxation of the implant leads to recurrence of the deformity, whereas no inconvenience is caused by the opening of the joint. These pitfalls led to the use of a modified technique in which the cartilaginous implant is introduced into the supra-meniscal cavity of the temporo-mandibular joint.

[Mandibular laterognathism and its treatment]. / A propos des latérognathies mandibulaires et de leur traitement.

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.
