[Cutaneous microvascularization after tissue expansion: experimental study in rats. Proposal of a method for monitoring the expansion by measuring the transcutaneous pressure of oxygen].

Major complications can occur during cutaneous expansion. They appear to be related to microcirculatory disorders. An experimentation in the rat demonstrated a significant difference in the results depending on the protocol adopted (slow or rapid expansion). Complications occurred in the case of rapid expansion. The results for TcPO2, histology and capillaroscopy corroborate the clinical data. The authors show that measurement of the TcPO2 has a predictive value in relation to complications. They propose the use of this technique in human clinical practice. The TcPO2 and the cutaneous oxygenation index allows control of tissue expansion in order to prevent the development of complications.

[Augmentation rhinoplasty using bone graft. Technical aspects and therapeutic deductions].

Reviewing 45 cases of augmentation rhinoplasties with bone grafting the authors discuss some technical points and the choices of their indications: donor site, incision, patterns of graft implantation depending on clinical examination which selected the cases where exogenous material from the nose is needed for reconstruction. A columellar support seem to them necessary to correct collapsed noses and in these cases a mortise and tenon joint has been employed. When a pure saddle nose deformity exists, a biomaterial can be used reducing morbidity of an iliac bone graft.

[Therapeutic measure in the repair of traumatic loss of substance of the scalp].

Repair of scalp tissue losses must reach two ends: Cover cranium and its contain while restoring hair. Only scalp flaps can attain these aims, but their disadvantage is most of the time to shift alopecia. For the major tissue losses, since skin expansion, treatment proceedings have changed: an immediate and temporary cover by a skin graft can be proposed, instead of multiple scalp flaps or free flaps. Few cases illustrate this alternative allowing discussion about their respective indications.

[Expansion prostheses in restorative and esthetic surgery of the head].

The authors discuss the results of 29 cases of tissue expansion, using 40 expanders, at the head and neck level, in an attempt to achieve a constructive self-criticism. The results have been classified into excellent (18 over 28 cases), good (4/29), fair (3/29) and poor (4/29). Complications were those usually reported: pain, infection, wound dehiscence, reservoir failure. In summary, 23 of 29 patients have definitely gained from tissue expansion. The remaining 6 cases considered as failures are carefully discussed leading to some practical conclusions.

[The YAG laser in children's conservative dentistry. Preliminary report].

The authors give a preliminary report of the use of a high-power (60 W) pulsed Yag laser in conservative odontology. A purely experimental phase involving laser shots to 164 freshly extracted teeth preceded the clinical evaluation. Sterilization was obtained in all cases. Histopathological sections showed that there was destruction of caries with carbonization, and melting of the superficial layer despite complete preservation of the pulp. The clinical study which followed involved 28 milk teeth. In 9 cases local anesthesia was of no value. In all cases there was vaporization of the pathological dentition and vitrification of the superficial dentin layer. Pulp vitality tested before and sometime after the procedure was preserved in all cases. These are the results reported here with a review of the probable future possibilities of the Yag laser.

[Ameloblastoma in an 11-year-old child].

The authors report a case of ameloblastoma occurring at the unusual age of 11 years. The surgical management is conservative. Complete and careful tumorectomy was performed without reconstruction. Complete spontaneous restitution was seen one year after the operation. No recurrence was seen and the patient may new be considered as cured, with a 6 year follow-up.

[Treatment of malignant melanomas. Trial of D.T.I.C. by intra-arterial infusion].

D.T.I.C. appears more and more to possess the characteristics of an effective chemical agent in the treatment of naevocarcinoma. Having been able to include it in a mixed chemotherapy programme used in a group of 44 patients, we report here our findings. This is a preliminary study, the results of which will have to be confirmed in time on a larger group of patients over a longer period of observation.

[Functional anatomy of the superfical temporal blood vessels].

Functional study on superficial temporal vessels. These vessels appear to have a board territory on--the horizontal part of the scalp--the superior lateral face--the anterior and superior half of the external ear The terminal part of these vessels and the rich anastomotic system is particularly studied. This system passes the middle line; the anastomoses are in the fascia superficilialis. Secondly there is a sub-dermal plexual formation which is in a parallel direction to the vessels. Practical consequences can be found--in neuro-surgery--in plastic-surgery--and in the new surgery of cutaneous transfer with micro-anastomoses of the vessels.
