[Interposition of a full-thickness skin graft in the surgery of temporomandibular joint ankylosis. A study of 31 cases of which 20 had long-term follow-up].

Recurrence is the main problem in temporo-mandibular joint ankylosis treatment. Two therapy are used against this, physiotherapy and surgical joint interposition. Following ankylosis removal, many materials can be interposed but, for us, fullthickness skin graft using Popescu and Vasiliu technique seems to be the best and simplest one. This retrospective study of 31 cases, 20 with long-term follow-up, shows that good results are obtained using this skin graft, with 90% successful rate.

[Surgical anatomy of the parotid region. Current concepts].

Three zones of the parotid region situated in the cervicofacial area were studied. The bilobular architecture of the parotid gland, the relations between the facial nerve and the parotid gland and the cover plans are described. On the posterior border of the parotid there is a cleavage interlobular point where the facial nerve penetrates and can be dissected. Thus the facial nerve has four parts designated as retro, inter, intra and preglandular. The parotid gland and is surrounding capsula is covered by a superficial musculoaponeurosis and the skin. The musculoaponeurosis is used in cervicofacial lifting procedures and palliative treatment of facial palsy. It can also be used in certain situations (primary tumours of moderate size without capsula involvement) to fill retromandibular depressions after total parotidectomy.

[Mandibular reconstruction using a metallo-acrylic implant prosthesis in oncology. Apropos of 40 cases].

The authors report on 40 cases using acrylic-metal prosthesis after ablative cancer surgery and compare them with the literature. The long-term complications (prosthesis extrusion or infection) are important, but the short-term follow-up (3 months) is more than 80% of success, any material used. The prosthesis keep a physiological position to the mandible, against scar sequelae. The use of soft tissue closure without post-operative radiotherapy increase the success of a simple-used and low-priced device of mandibular reconstruction.

[Current surgical approach to masticatory system pain-dysfunction syndrome (except arthroscopy)].

The surgical treatment of SADAM concerns patients with irreversible lesions who continue to complain (disk displacement with pain and limited opening, painful arthrosis) after all the other therapeutic options have been unsuccessful and when no long-lasting improvement can be reasonable expected. Indications for surgery have declined with progress in aetiological treatment, particularly of occlusion, and arthroscopic treatment, but arthrotomy is the only remaining technique feasible in certain cases. SADAM should be a conservative surgery, protecting the disk (repositioning displaced disks, repairing perforated disks) and the articular surfaces (correcting bone irregularities). Anatomic and functional reconstruction of the joint cannot be successful unless the cause of the dysfunction is treated at the same time.

[An osteo-cartilaginous graft for ankylosis].

Ankylosis of the temporomandibular joint was treated by resection of the ankylosed block and arthroplasty with an osteo-cartilage graft from the rib. The main feature was attaching the cartilage to the bony surface and the appearance of enchondral ossification. The value of this method is discussed.

[Indications for imagery in dysfunctional temporomandibular pathology].

Cranio-mandibular disorders include muscular and articular signs. Articular pathology is the only one that need to be structurally studied. Paraclinic indications are based upon physical examination. Bone structure can be explored with tomography or CT scan and intra-articular structures can be explored with M.R.I. or arthrography. Two pathologies have then been found with an excessive frequency, disc displacements and juvenile osteoarthrosis.

[Aneurysmal cyst of the maxilla. Apropos of a case].

A case of extensive aneurysmal bone cyst of the maxilla is described, with a recurrence 2 years after surgical curettage, treated by new curettage and radiotherapy. The pathogenesis of this pseudo-cyst is yet obscure. While CT (and MR) demonstrate characteristic fluid-fluid levels, the diagnosis remains histological. A long survey, based on radiography, is necessary to detect recurrence.

[Otologic manifestations of the pain dysfunction syndrome of the stomatognathic system].

Phylogenesis, ontogenesis and anatomy explain the close relationship between temporo-mandibular joint and the middle ear and can therefore help understanding otologic symptoms such as: otalgia which often correspond to articular and muscular pain irradiation (coming from sterno-cleido-mastoid, lateral and medial pterygoid, deep layer of the masseter and temporal muscles); acouphens and ear block sensation that could be caused by a spasm extension of the manducatory (i.e. medial pterygoid) to levator and tympani tensors. These three muscles, which originate from the first branchial arch, have a proprioceptive sensitivity and share the same innervation. What is more tensor and levator veli exchange certain muscular fibers. Tensor tympani spasm can be held responsible both for a decrease or abolition of the Klockhoff's reflex, together with a decrease of the stapedian reflex, the latter due to tympani rigidity induced by a spasm of the tensor tympani.

[The discal system of the temporo-mandibular junction].

The discal apparatus represent the intra-articular part of the lateral pterygoid muscle tendon, which is differentiated in front of articular surfaces. It is involved in craniomandibular shock absorbing, joint proprioception, and also plays an important part in both condylar growth and morphogenesis. This is to emphasize the different roles of this apparatus, which should be religiously preserved, its lesions being, most of the time, irreversible and cause of TMJ disorders.

[Complications of temporo-mandibular arthroscopy. Report of 100 arthroscopies].

TMJ arthroscopy is a little invasive and of poor morbidity procedure of both investigation and treatment of temporomandibular pathology. A highly equipped operating room (double instrumentation) together with fine skill and proper knowledge of arthroscopic joint anatomy can easily prevent the rare complications described (articular, vascular, neurologic and otologic).

[Temporomandibular joint pain-dysfunction syndrome after whiplash injury. Medico-legal problems in common law].

In four cases, the authors analyse the medical and legal factors which lead the expert to his conclusions in french law, concerning temporo-mandibular joint dysfunction after whiplash injury indemnification. An uncertain direct link between the injury and the damage together with the patient's dental prior state to the accident, lead to retain an incomplete legal imputability. The compensation awarded to the victim will consist of an overvalued extra-patrimonial damage which will eventually be able to balance a low physiological deficit price.

[Traumatic false aneurysm associated with closed fractures of the mandible. Apropos of 3 cases].

The authors report 3 cases of trauma induced false aneurysm (internal maxillary, external carotid and internal subpetrous carotid arteries) associated to closed mandibular fractures. These rare vascular complications of ill-defined pathogeny are often due to high speed facial impact. Clinical presentation is polymorphous (pseudo-parotidis, neurological deficit) and arteriography is the main step of the paraclinic investigation. The treatment essentially depend upon both the location and the evolutivity of the false aneurysm.

[Fractures of the condylar region].

Condylar fracture are responsible for: homolateral TMJ disorders following discal apparatus lesions such as: disc displacement, discal lesion, osteoarthrosis of articular surfaces (condylar and temporal), contralateral TMJ disorders, more frequent, with destabilisation of the masticatory apparatus and decrease of ramus height or compensatory hypermobility. Functional treatment can prevent articular and muscular ankylosis. It is often indicated: non-displaced low undercondylar fractures or after surgery. Surgical reduction is indicated in two cases: displaced-low undercondylar fracture. The discal apparatus is intact and function usually excellent, displaced-high undercondylar fractures with 90 degrees head luxation. The bone reduction and contention must be associated to discal apparatus control. If dislocated or displaced, the apparatus should be replaced and sutured. Four factors are implicated in articular function: the fracture position, bone displacement (condylar head in or out of the glenoid fossa), discal apparatus integrity (the lower layer of the retrodiscal tissue is involved in bone regeneration especially in infants), and the quality of occlusion.

[Temporomandibular joint arthroscopy. Therapeutic aspects].

Arthroscopy is an interesting and enlarging technique that visualise the temporomandibular joint and allows surgical technics such as lysis and lavage, prediscal section, retrodiscal cauterisation, oblic protuberance cauterisation, disc suturing or shavering of the articular surfaces.
