[Tissue expansion. Presentation of a model of external filling valve].

Based on their experience of facial tissue expansion, the authors present a model of an external filling valve and illustrate its advantages in 9 cases in which 13 external valve were used: painful injection, absence of leakage, fast and confortable filling. The indications are sequelae of facial burns, face scars, treatment of orbito-temporal neurofibromatosis. The major advantage is rapid tissue expansion which reduces the problems of infection and skin loss.

[Cutaneous extension of parotid carcinoma].

INTRODUCTION: Telangiectatic cutaneous metastases are mostly associated with breast carcinomas. We report a case which was developed from a parotid tumour. CASE REPORT: A 63-year-old patient presented an erythematous, telangiectatic, rounded, cutaneous lesion of the cheek developed over a parotid tumour. Metastatic lymph nodes were observed in the drainage area of the tumour. Cutaneous histology revealed the presence of neoplastic cells in dermal vessels. After its surgical excision, histology of the parotid tumour showed an undifferentiated adenocarcinoma. Cutaneous lesions disappeared with chemotherapy. CONCLUSION: Two similar cases of inflammatory and telangiectatic cutaneous metastases associated with parotid carcinomas were reported previously. This metastatic localization to the skin could be due to special anatomic conditions and perhaps to the similarity of some surface antigens between skin vessels and parotid carcinoma cells.

[A variant of island flaps for the covering of pressure sores: the hatchet flap. Apropos of 31 cases].

The authors propose a modification of the classical design of island flaps for cover of pressure sores, applied to gluteus maximus and tensor fascia lata muscles: the hatchet flap. 31 flaps have been used including 13 gluteus maximus superior flaps for sacral pressure sores, 9 gluteal inferior flaps for ischial pressure sores and 9 tensor fascia lata flaps for trochanteric pressure sores. A small partial necrosis and two cases of sepsis were observed in this series, but did not require surgical revision. The authors emphasize the value of this modification of the classical flap design, which preserves an even better musculocutaneous capital in these patients, who are often already multi-operated. The very rapid recovery of patients supports the authors' application of hatchet flaps to the surgery of pressure sores, and suggests the extension to other musculocutaneous flaps in the future.

[Patents and innovations. Definitions--modes of action].

The author presents the various methods available for the doctor to protect and exploit his inventions or technological discoveries. In the medical field, as in other fields, there are three titles of industrial property: patent, registered model and trademark. The modalities of each of these titles are explained. Based on the his own experience, the author presents advice concerning the use of patents, contracts and the choice of industrial partners.

[Reconstruction of the medial canthus in oncology. Apropos of 105 cases over 9 years].

Without forgetting that resection of a malignant tumour must always take priority over the problems of reconstruction, based on a series of 105 cases of medial canthus lesions, the authors believe that: for tumours with a reserved prognosis, particularly sclerodermiform basal cell carcinomas of the orbit, full thickness skin graft is the most appropriate technique; for cases with a good prognosis, the cosmetic result takes priority. An intersuperciliary island flap is currently the method of choice; for advanced cancers of the medial canthus, the combination of frontal flaps and nasolabial flaps is the procedure which gives the best aesthetic and functional results. This series includes three cases of radical orbital exenteration, including two because of sclerodermiform basal cell carcinomas, and the authors stress the very serious prognosis of these tumours in the orbit, especially in the presence of a recurrence in an irradiated territory.

Attempt at systematization in the treatment of isolated fractures of the zygomatic bone: techniques and results.

Two series of cases with isolated zygomatic bone fractures have been compared with regard to the treatment applied and its results, i.e. 258 cases treated by conventional methods, and 437 cases treated by osteosynthesis with miniaturized screwed plates (MSP). In the second series, reduction failure is eight times less frequent than in the first series, and fixation by plates is solid in the three spatial planes. The incidence of postoperative infra-orbital nerve sequelae was diminished by 50% in the second series. This easy, comfortable and efficient method is now used by the authors for the treatment of all unstable zygomatic fractures and in all cases presenting the following functional signs: limited buccal opening, diplopia by trapping, or involvement of the infra-orbital nerve.

[Facial osteotomies without fixation].

The authors first review the problems associated with inter-maxillary blockage and of classical methods of immobilisation used in all types of facial osteotomy. Their experience of osteosynthesis in traumatology has led them to use whenever possible osteosynthesis alone with screw fixed microplates. The other methods are used only as secondary assistance in the case of necessity. Osteosynthesis without blockage prevents recurrence and does not compromise the result as far as satisfactory dental articulation is concerned.

[Study of stresses in the fractured mandible in man. Theoretical measurement and verification by extensometric gauges in situ].

The authors study the various possibilities for measuring the stresses which develop within the mandible under the effect of masticatory forces. Several methods are proposed:--calculation with the aid of mathematical models,---the use of extensometric gauges in vitro with the aid of traction machines,--the use of extensometric gauges in vivo. The results obtained with all three methods are in agreement and, in the opinion of the authors, provide experimental evidence of the well-founded nature of Michelet's technique of osteosynthesis.

[Mandibular synthesis. Placement of the synthesis as a function of mandibular stress].

After recalling Michelet's principles of mandibular osteosynthesis, the authors relate their experiences after 18 months of biomechanical analysis. They define the best locations for osteosyntheses according to calculations of when flexion and torsion occur, taking anatomical conditions into account. Details are given of the position of the plate or plates according to the location of the fracture or osteotomy (horizontal branch, symphysal and para-symphysal region and angle). Analysis of stresses within the osteosynthesized mandible has resulted in the development of what seems to be a reliable medium. One hundred anf forty facial osteosyntheses they have carried out confirm their faith in the safety of the method.

[Fronto-malar osteosynthesis by means of screwed plates].

The external orbital apophysis provides a zone of solid anchorage for the treatment of fractures as well as for the immobilization of osseous fragments after facial osteotomy. While proposing new miniaturized material the authors present 45 cases of fronto-malar osteosynthesis carried out in one year. They recall that solid immobilization by plating avoids inter-maxillary blockage, and is the only means of restraint among those presently used which is capable of opposing late post-operative recession. Consequently after facial osteotomy, the plates are left in place for 12 months. They are removed under local anethesia.
