RESUMEN
In severe cases of microphthalmos or anophthalmos, the bony orbital cavity is often too small to allow one to create a satisfactory socket for a prosthesis. An omnidirectional expansion of the orbit, by osteotomies done in a step-like fashion, allows the creation of a larger bony cavity and improves the symmetry of the face. The risks of the craniotomy and of the mobilization of the free bone pieces are discussed.

What is new in the field of mammary prostheses? In answer to this question, the authors reply "Nothing". They stress the need for a new approach to the problem of capsular contraction based on: 1) experimental research aiming at identification of the collagen and the capsular fibroblasts, by cell culture, in particular; 2) the abandoning of horizontal in favour of longitudinal statistics based on prolonged multifactoral observation of the largest possible number of patients; 3) greater scientific rigour in the analysis of prosthetic insertion in augmentation mammoplasties and mammary reconstructions. In this connection, they describe their own technique for augmentation mammoplasties by insertion of an inflatable prosthesis placed retropectorally by an areolo-mamillary approach.

Micro-orbitism which follows the very early arrested development of the optic vesicles hinders the fitting of a prosthesis. A total enlargement of the orbit is proposed which restores the normal dimensions and enables facial symmetry to be re-established. The risks and advantages of this procedure are discussed.
