[Quality of life after primary parotidectomy for benign tumor].

Introduction: Parotidectomy is commonly performed for various indications, including benign tumors of the parotid region. Esthetic or functional sequels of various importance and lasting effects may occur, as after any surgical procedure. These disorders may impact the patient's quality of life.

[Hemophilic pseudotumors of the jaws].

Hemophilic pseudotumors are observed in 1 to 2 % of severe hemophilia cases. They are very rare in the maxilla and mandible. Traumatic etiology is the most frequent.

[Globulomaxillary cyst].

Globulomaxillary cysts are located in the globular and maxillary process fusion area; they are not of odontogenic origin. Their etiology is similar to oral and facial clefts, which explains why they are classified as ontogenic fissural cysts. However, some clefts are not localized precisely on the premaxillary and maxillary process fusion area and their etiology as globulomaxillary cysts is questioned.

[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.

[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.

[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.
