[Removal through the coronal approach of the upper wisdom teeth. Apropos of a case of bilateral migration into the temporal fossa]. / Avulsion par voie coronale de dents de sagesse supérieures. A propos d'un cas de migration bilatérale dans les fosses temporales.

This report presents a case of double migration of third maxillary molar in temporal fossa and their removal by a coronal approach. A 15 years of old boy, was seen for major trismus. 2 months before, he underwent under general anaesthesy impacted third maxillary molar removal. The radiologic examination showed that superior third molar has been pushed and left into the temporal fossa in both sides. After computed tomography examination, teeth were removed by a coronal approach. This was the only approach in order to preserve facial nerve and to allow with good chances to remove the teeth. Intervention was successful. Postoperative course was uneventful. The buccal apperture was normalized three months after surgery.

[The premaxilla and facial growth 68 years later]. / Prémaxillaire et croissance faciale 68 ans après.

The thesis of Dr Etienne Cadenat on the embryology of cleft-lip dates from 1924. From this epoch onwards it was demonstrated that the human premaxilla had a specific development not corresponding to that of other mammals, in whom the suture between the pre- and post- maxilla is active and participates in the sagittal, transversal and vertical growth of the maxilla. Numerous studies have been undertaken to verify that the human premaxilla does in fact exist, and several have gone as far as to conclude in its non-existence. The author restudied the question from the histologic angle, and showed that the zone of union between premaxilla and maxilla did not contain any histologic elements that could identify a growth suture. Indeed, the spatial orientation of this suture would not allow anteroposterior growth. It can be concluded that the human premaxilla does exist but its specificity has again been demonstrated.
