[Reconstruction of the temporomandibular joint and its alternatives].

Reconstruction of the temporomandibular joint is always quite problematic. --Use of a prosthesis. Many prostheses have been propounded to deal with the operational problems. As, in our opinion, these seem not to meet the usual orthopaedic surgery requirements, we developed a totally intermediate prosthesis with non-sealed cupula. The use of this prosthesis, whenever feasible, provides the solution for the problems with which we have to contend during reconstruction surgery in traumatology and degenerative or tumoral disease. Nonetheless, its use remains limited to adults. --Utilization of biological material: following numerous attempts made with the conventional osteocartilagenous grafts (metatarsal, rib), we believe that the proper orientation, walking in Chang's footsteps, is toward the use of the head of the second metatarsal bone as a microanastomotic transfer. It seems to us that this technique must be used in children, particularly those with malformation syndromes or ankylosis.

[Posterior cranial dysmorphy. Classification and an original technic of correction: parieto-occipital transposition].

The posterior part of the skull, frequently overlooked, is altered directly and indirectly in numerous pathological situations. Lesions of the cranial contents, alteration of the lambdoid suture, abnormal constraints related to posture or to muscular activity modify the posterior curvature of the skull, generally in the form of flattening. Examination of the posterior part of the skull is essential in the context of neurosurgery and craniofacial malformations. The dysmorphy can be corrected by an original, personal technique of biparieto-occipital transposition restoring a harmonious curvature allowing immediate weight-bearing.

[Computerized tomography in the diagnosis of craniomandibular disorders: radiological-surgical comparison].

Among 500 C.T. scan of temporomandibular joint (T.M.J.), examined since 1982 by bilateral direct sagittal method (Department of Radiology, Pr. A. TREHEUX, C.H.U. Nancy-Brabois), the authors have retained 14 cases of patients with symptoms related to dysfunction of the T.M.J. cured by surgery (Department of Maxillo Facial Surgery, Pr. STRICKER, C.H.U. Nancy). These cases were chosen among hundred patients annually examined by C.T. scan, for various diseases (dysfunctions of the T.M.J., traumatisms, infections, inflammatory diseases...). These correlations between radiology and surgery about 26 T.M.J. (2 patients underwent surgery only on one side) were: an accuracy with surgical findings for 19 cases (76%); in 6 cases (23%), a meniscus anteriorly displaced, non detected by C.T. scan was found by surgery; 2 cases of meniscus perforations (one in the frontal plane, the other sagittal) were surgical findings; in 1 case, a displacement was under-valued by C.T. scan; in 3 cases, arthrosic changes (1 case of REITER syndroma) were characterized by C.T. scan. The authors emphasize the value and the limits of evaluation of the internal derangements of the T.M.J. with direct sagittal C.T.

[The CT scanner and the temporomandibular joint. Anatomo-radiologic comparisons. Apropos of 14 cases of algodysfunctional of the manducator system].

Among 500 CT scan of temporomandibular joint (TMJ), examined since 1982 by bilateral direct sagittal method (Department of Radiology, Pr. A. TREHEUX, CHU Nancy-Brabois), the authors have retained 14 cases of patients with symptoms related to TMJ's dysfunction cured by surgery (Department of Maxillo Facial Surgery, Pr STRICKER, CHU Nancy). These cases were chosen among hundred patients annually examined by CT scan, for various diseases (TMJ's dysfunctions, traumatisms, infections, inflammatory diseases...). These correlations between radiology and surgery about 26 TMJ (2 patients underwent surgery only on one side) were: an accuracy with surgical findings for 19 cases (76%); in 6 cases (23%), a meniscus anteriorly displaced, non detected by CT scan was found by surgery; 2 cases of meniscus perforations (one in the frontal plane, the other sagittal) were surgical findings; in 1 case, a displacement was under-valued by CT scan; in 3 cases, arthrosic changes (1 case of Reiter syndrome), were characterized by CT scan. The authors emphasize the value and the limits of evaluation of the internal derangements of the TMJ with direct sagittal CT.

[Plagiocephaly. Craniofacial asymmetry with variable curling-up].

The plagiocephaly syndrome is an asymmetrical cranial deformity due to premature synostosis of a coronal hemi-suture. The predominant alteration is at the spheno-frontal suture. The classification is attempted between the isolated plagiocephaly (P) an plagiocephaly with hypertelorism, on one side, that are to be distinguished from complex asymmetrical cranio-facial deformities. The frontal P. are differentiated from occipital P (pachycephaly) and from mixed hemi-cranial P. The deformity affects the fronto-orbital region situated anterior to the synostosis. The coronal suture incurves around a pivot formed by the lateral orbital pillar and the pterion, giving rise to a set of facial and cranial deformities, variable according to the precocity and the topography of the synostosis. Investigating the syndrome is clinical and radiological. The deformity reveals itself in 88% of cases, the affects are mainly orbital and ophthalmologic. The authors insist on the necessity of a bilateral orbito-fronto-nasal osteotomy, as a therapeutic act that gives better harmony on short and long term; on the other hand, they draw the attention to the importance of abolishing the synostocic lock by the resection of the lesser wing of the sphenoid extended till the superior orbital fissure and the resection of the outher periosteal layer of the dura matter which allows a remodeling effect the growing brain. The results and complications are evaluated on 44 operated children.

[The influence of the masticatory muscles on craniofacial growth. A microsurgical study in the rat].

Possible influence of masticatory muscles on facial growth was investigated in the rat by the formation of several experimental groups: excision of right masseter muscle of right temporal muscle, of both masseter muscles, of both temporal muscles and of both masseter and temporal muscles, section of inferior maxillary nerve and masseter transplantation. Results demonstrated that overall masticatory muscles provided equilibrium of masticatory function, any rupture of this equilibrium producing effects on mandibular growth and that of the facial mass.

[The upper buccal vestibule in clefts].

The buccal vestibule is described and its physiologic interest with respect to the position of alveolar processes emphasized, the latter being compromised by the cleft and its repair. The need for its restitution to ensure function of good quality implies the use of a total skin graft before school age for cases of total bilateral clefts.

[Experimental factors influencing the growth of the jaws].

An experimental study evaluated the effect of various surgical procedures on maxillary growth. Raising and excision of palatine muco-periosteum did not modify facial or palatine growth. Resection of the bony palate showed the non-essential nature of the medial palaxine suture during normal growth, even in the transverse direction. Coagulation of the two posterior palaxine arteries disturbed palaxine growth, but ligature of the external carotid artery failed to alter facial growth. Several tests were carried out to determine the importance of functional matrices: excision of facial nerve trunk did not affect bone growth, destruction of the trigeminal provoked obvious disturbance of craniofacial growth while obturation of a nasal fossa produced no observable anomaly. Enucleation demonstrated the need for an intact globe for normal orbital growth, and resection of the mandibular condyle showed the primordial role of cartilaginous centers in mandibular growth.

[Scaphocephaly. Treatment and complications apropos of 115 cases].

The authors report, concerning 115 cas of scaphocephaly, the clinical (spheno., lepto., bathmo., clino., the kinds without dolichocephaly) radiological characteristics (temporal curve without dolichocephaly), orbito-sphenoidal obliquity regressing after treatment). They discuss the accepted ideas of the merely morphological problems of this type of craniostenosis, about their clinical and X-ray findings of encephalic disorder. The therapeutic methods are stated, so are the complications met during the surgical treatment. They suggest the craniectomy, taking away the sagittal suture associated with the linear coagulation of the dura mater. To the median sagittal craniectomy, one can add retrocoronal, pre lambdoid or metopic craniectomies according to the type of scaphocephaly. This treatment is simple, efficient and not very dangerous during the first year.
