[Dynamic bimaxillary osteotomy: the new occlusal base].

The authors present an ortho-surgical method which unites occlusion and aesthetic without compromise and without stopping orthodontic work during the immediate post-operative period. The occlusal preparation permits us a global and simultaneous mobilisation of the two maxillars which are ostesynthezed in posterior skeletal disclosing. This disposition allows a lingual replacement and gives more facility to an eventual immediate post-operative occlusal replacement. The stiff osteosynthesis with immovable plates realize a therapeutic dissociation between the skeletal stage and the basal alveolo-dental stage. The "proprioceptive amnesia" and the "muscular sideration" permit a proprioceptive reorganisation and a new neuro-muscular fonctionnement elaborated from a new occlusal base. The free movements of the T.M.J. facilitate these acquisitions and allow a perspective supervision of the occlusion in a dynamic perspective.

[Choice of a central analgesic for anesthesia with spontaneous respiration].

The ventilatory effects of tramadol (T) and nefopam (N) are evaluated in anesthetized patients with enflurane in a closed circuit breathing system and compared with the effects of pentazocine (P). The following parameters tidal volume (VT), minute ventilation (V), CO2 (capnometry) occlusion pressure (OP), ventilatory response to hypercarbia are recorded after 30 minutes of anaesthesia, before and after repeated injections of the analgesics, P: 15 mg, N: 40 mg, T: 100 mg are injected I.V., and analgesics administration is repeated at 30 minutes interval, so that the patients receive a total P dose of 30 mg, a total N dose of 60 mg and a total T dose of 200 mg. The administration of 15 mg of P induces a change in VT (-24%), ventilatory frequency (-40%), OP (-18) OP only returns to basal values after a second dose. The ventilatory response to hypercarbie is indeed satisfying (increase of 61% in V). After N and T, ventilatory frequency is not disturbed. V increases of 16% and 11% respectively after the first injection, and of 31% and 2% after the second injection. OP increases by 39% and 56% respectively after the first injection and gets better over time with nefopam (+ 58%), 30 mg of P. 20 mg of N and 100 mg of T are equivalent for analgesia.(ABSTRACT TRUNCATED AT 250 WORDS)

[Technical aspects of reconstruction of the mandibular region using composite flaps of the latissimus dorsi].

Anatomical data from 20 laboratory dissections are employed to describe a composite flap associating skin, the latissimus dorsi muscle, and ribs, important anastomoses existing between the intercostal and inferior scapula vascular systems. Two cases were treated by single-stage extensive reconstruction of the mandibular region employing this osteomusculocutaneous flap of the latissimus dorsi.

[Pulsed Brain-Spoerel system a new closed-circle system (author's transl)].

A pump is used to reinsert the expiratory gas of a Bain Spoerel system into the circuit. It delivers a 14 l.min-1 flow. The expiratory gas is drawn across a CO2 absorber and fresh gas flow is reduced to the patient's VO2. The technic cumulates the advantages of the closed system to the Bain Spoerel system: practical design for head surgery, no valve, then less energetic loss by the patient in spontaneous ventilation, convenient gas flow, adapted to the small child, because of small dead space, economy of drugs, ecology: no more pollution ! humidification and warming of inspired gas. A hundred patients have been so anaesthetized in head surgery without any problem.
