[The processes of osteotomy in ocular surgery. Introduction of a new type of oscillating osteotome (author's transl)].

The authors recall the different technics of bone approach in the dacryocystorhinostomy, the orbital osteosynthesis, the resilient buckling of the lids, the restoration of the medial palpebral ligament and the orbitotomies by temporal way. The processes that utilize a circular oscillating trephine or a saw with oscillatory motion seem to be suitable to most of these operations. A new type of oscillating osteotome is offered.
