title: [Plastic reconstruction of the anchyotic region from a cephalothoracopagus rabbit with prosophthalmy and cebocephaly (author's transl)].
abstract: 1. By means of radiographies, of microscopic serial sections and of a cardboard geometric reconstruction (magnification 80), an investigation has been made of the more complete "anterior" face of cephalothoracopagus rabbit with anchyoty, synoty, otocephaly, prosophthalmy and cebocephaly. 2. All details are organized according to a well precise plan: a. all structures touching the principle plane of symmetry are fused; b. everything which would exist beyond that plane did not develop. 3. The heads of mallei are fused. The nearly normal auditory ossicles build a transversal chain. The bases of stapes are thickened. The centres of ossification of the heads are fused but normal. Each Corpus incudis shows a normal centre of ossification. 4. The outer epithelial rudiments of the tympanic membranes remain separated by a cleft. 5. The derivatives from the first branchial arch are defective, the anterior processes of malleus being fused. The lack of Meckel's cartilages induces cebocephaly, which provokes itself prosophthalmy and otocephaly. 6. There is a clear tendency-even in the deeply altered regions-towards a harmonious symmetry.
