[Maximal isometric bite force and sports. Preliminary study].

INTRODUCTION: The evaluation of the bite forces coupled with EMG activity of masseter muscles allows to point out temporo-mandibular joint disorders. The intense practice of sports induces stress which may affect the mandibular statics, due to an hyperfunction of the elevator masticatory muscles, especially the masseter muscles. This concept has led us to compare the maximum isometric bite forces of sedentary and physically trained subjects. MATERIAL AND METHODS: The aim of this experimentation is to study the maximum isometric bite forces of the premolars, with a force transducer, for two groups of physically trained and sedentary volunteers (25 subjects), with distinction between male and female subjects. Subjects with normal denture and no temporo-mandibular joint disorder were retained. EMG and force recording were synchronized and recorded during 10 seconds of maximal contraction. RESULTS: The male subjects developed a maximal bite-force significantly higher (p < 0.05) compared to the female subjects. There is no significant difference between subjects practising a sport (at least 6 hours a week) and sedentary ones. The evolution of force during the contraction is different between sexes. EMG activity allowed to control that subjects developed a maximal force and an increase in muscular fatigability of physically active females compared to sedentary ones was noticed. DISCUSSION: The difference of maximal force between men and women is similar to the one found for the locomotor muscles. The analysis of the evolution of the force according to the contraction duration, might be linked to a different distribution of muscular fibers according to the sex. The practice of a sport might increase the fatigability of the masseter muscles and might be a factor inducing a muscular imbalance of the mandibular posture. But the relatively low number of subjects and the absence of well defined distinctions between different kinds of sport limit our conclusions.

[Cervical ganglioneuroma. Review, apropos of a case].

We describe a case of cervical ganglioneuroma, an uncommon benign tumor which develops slowly, predominantly in females and infants. Ganglioneuromas have a neuroectodermic origin and are localized along the sympathetic trunk. Most are unmasked fortuitously by palpation or by high serum catecholamine levels proportional to tumor size. After radiographic exploration and surgical excision, a pathologic study of the surgical specimen is required to identify this very differentiated tumor stemming from the neural crest.

[Treatment of fractures of the orbital floor: reconstruction using Teflon sheets. Analysis of the results after 5 years].

We report our experience with fractures of the orbital floor over the past five years, reporting 80 cases. Different anatomic and clinical forms were defined, particularly trap-door fractures. After a clinical and computed tomography study, we recommend treatment with Teflon implants. Results obtained were analyzed and compared with other series in the literature.

[Facial epitheliomas: general considerations, surgical techniques and indications].

Carcinoma of the face is the skin disease most frequently encountered by plastic surgeons in everyday practice. Although basal cell carcinomas and squamous cell carcinomas are generally easy to recognize, their treatment remains subject to various schools of thought, or even individual practices, which are often difficult to define. This article defines a general plan of management of these tumours; their histological duality corresponds to a therapeutic duality. Resection of a basal cell carcinoma requires safety margins of 3 to 4 mm, versus at least 5 mm for a squamous cell carcinoma. In a high-risk subject, with a sclerodermiform carcinoma or undifferentiated squamous cell carcinoma, this safety margin may be as much as 10 mm or more. Frozen section examination is preferable in these situations. Six anatomical regions are studied selectively to define the main rules of reconstruction: nasal region, orbitopalpebral region, labial region, malar region, frontal region and auricular region. Each region will be subdivided into several subterritories, each requiring different strategies. The objectives, methods and indications of each reconstruction are selectively defined. The final strategy proposed is based not only on the author's personal experience, but also on the results of the national survey on carcinomas. As a complement to these therapeutic guidelines, the authors raise the problem of incomplete resection, which requires the definition of a peripheral infiltration index predictive of the recurrence rate. Surgery obviously cannot constitute exclusive treatment carcinomas, hence the value of presenting other methods currently available in the therapeutic armamentarium. Surveillance is essential in every case, determined by the patient's risk of recurrence or even metastatic dissemination.

The osteocutaneous upper arm flap for mandibular reconstruction.

The authors present the osteocutaneous upper arm flap as useful in segmental microsurgical mandibular reconstructions. This flap presents several advantages: easy and rapid dissection; a long and reliable pedicle; excellent segmental blood supply to the bone, allowing multiple osteotomies; remarkable mobility of the skin paddle relating to the underlying bone; and minimal donor-site morbidity. Among its few disadvantages are that the bone is predominantly cortical, and the bone shaft cannot exceed 11 x 2 cm. Nevertheless, this flap is an excellent alternative to conventional procedures, when a segmental reconstruction, requiring short bone segments and skin, is required. Eight consecutive clinical cases have been successfully treated and are reported.

The submental island flap: a new donor site. Anatomy and clinical applications as a free or pedicled flap.

This paper describes the use of a new island flap based on the submental artery. Previously described cervical flaps have inherent problems ranging from limited mobility to unacceptable donor-site scars, to unpredictable outcomes. The flap design and technique were studied on 20 fresh cadavers and 8 patients who underwent radical neck dissections. The flap was then used successfully for reconstruction of orofacial defects in 8 patients. The flap has a long (up to 8 cm), reliable pedicle, and cutaneous dimensions can reach up to 7 x 18 cm. It can be used as a cutaneous, musculofascial (cervicofascial and platysma), or osteocutaneous flap. This flap has an excellent skin color match and a wide arc of rotation, and can extend to the whole homolateral face, except for a part of the forehead and the whole oral cavity. The anatomy, the technique, and clinical experiences are presented.

[Role of osteocutaneous external brachial flap in the treatment of composite loss of substance of the mandible].

The authors report on their research begun in 1987 on this flap and its uses in reconstruction of composite defects of the horizontal and symphysical parts of the mandible, regardless of the cause of the loss. For treatment of average sized defects (less than 7 centimeters), it is reliable flap, easy to remove and to model by osteotomies, giving a thin skin mobile with bone and the removal of which results in only moderate development of scar tissue at the donor site.

[The normal mouth in newborn infants].

The mouth is the place where the newborn begins his experience of life. An anatomical study of the mouth and of the airways-digestive tract junction can explain the particular physiological features of suction and deglutition. These functions bear witness to the neonatal brainstem maturation, improve the newborn's waking state and are the sources of novel acquisitions in the field of interrelations between mother and child.

Mucormycosis in an apparently normal host. Case study and literature review.

Mucormycosis refers to an opportunistic fungal infection most often related to predisposing conditions, especially uncontrolled diabetes. It can occur as a rapidly extending rhinocerebral infection presenting a high mortality rate. The same micro-organism has, however, been identified in benign paranasal infections in the absence of a general debilitating condition, suggesting that host factors are of the utmost importance in the outcome of paranasal mucormycosis.

[The submental island skin flap. A surgical protocol. Prospects of use].

The authors report their use of a previously undescribed skin flap situated in the submental region and vascularised by the submental artery derived from the facial artery. It is possible to raise flaps as large as 11 cm X 6 cm with an identical colour to that of the face. The pedicle flap can reach any part of the homolateral oral cavity or the lower 2/3 of the homolateral side of the face (with the exception of the nasal region). The free flap, using a good calibre pedicle (including facial arteries and veins, may be as long as 7 cm and appears to be extremely reliable. It is also possible to use a distal or composite pedicle taking a segment of the internal basilar margin. The donor site scar dissimulated under the mandible is perfectly acceptable.

Sequential combination of 5-fluorouracil, cis-platinum and irradiation. 1. Advanced head and neck cancers.

Based on the synergistic action of 5-fluorouracil (5-FUra), cis-dichlorodiamminoplatinum(II) (cis-DDP) and gamma-rays, which was suggested in experiments on murine tumours, a sequential treatment combining irradiation and chemotherapy for human solid tumours known to be resistant to conventional treatments has been developed. A pilot study was carried out on 30 patients with recurring head and neck cancers previously treated by radiotherapy and surgery. The good tolerance and the initial results justified applying this protocol to previously untreated cases. The second study involved 40 patients with stage III and IV tumours. After 3 cycles of combined radio- and chemotherapy followed by a conventional radiotherapy, 78% were good responders (51% in complete remission). Oropharynx and oral cavity, without base of tongue, have a 51% actuarial survival at 3 years when they achieved an early complete remission.
