[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).

[Post-traumatic enophthalmos. Pathogenic, diagnostic and therapeutic approaches].

Post-traumatic enophthalmos has a complex pathogenesis, resulting from injuries to the bony walls of the orbit or to the intraorbital contents. Computed tomography allows specifying this pathogenesis by locating displaced bone, fat leakage or muscle incarceration, as well as calculating the volumes of the orbit and of the soft tissues. This assessment guides surgery (most often bone grafts), but correction remains limited by scar retraction, especially around the orbit. The prognosis of enophthalmos mainly depends on a general initial treatment after the trauma.

[Enophthalmos of the enucleated eye].

Even when it is corrected by an ocular prosthesis, enucleation often causes enophthalmos. After studying the integrality of the walls of the orbits with CT, the presence and position of the intraorbital implant must be controlled and the enophthalmos treated by compensating for the residual volume loss of the orbital content (bone or biomaterials) and, sometimes, filling up the upper palpebral space (dermal graft, galea flaps or biomaterials). The retraction of palpebral scars limits the possibilities of correction.

[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.

[Post-traumatic ptosis].

Traumatic ptosis is most often secondary to a fasciomuscular lesion of the levator system. Less frequently, it results from the paralysis of the levator muscle due to an injury to the third pair of cranial nerves. This ptosis is observed in comminuted orbital fractures or fractures of the base of the skull involving the orbital apex, and it is then associated with oculomotor paralysis. In favorable cases seen early, repairing surgery of the levator system produces excellent results. When associated with ophthalmoplegia or corneal anesthesia, neurogenic ptosis requires a watch and wait policy.

[The aging eyelid].

Eyelid involution affects all the tissues of the lid, including the tarsotendinous band and the levator muscle. Dermatochalasis can be complicated by ptosis, entropion or ectropion, which must be taken into account during assessment and treatment.

[Repair of enlarged orbital exenteration cavities].

An empty orbital cavity is always unesthetic-looking, but several plastic surgery procedures exist to attenuate the cosmetic damage. In case of exenteration affecting periorbital tissues and cavities, spontaneous epithelialization is preferable than a split skin graft. Except for rare cases, where it is indicated to preserve the conjunctivae and eyelids, covering up may be realized with minimal scarring using two flaps, one superficial jugotemporal, and the other deep mid-frontal.

[Use of a posterior temporal muscle flap in surgery of the temporomandibular joint].

The anatomical and physiological relation between temporal muscle and temporomandibular joint are well-knowed. The versatility of the temporo muscle-fascia flap must be stressed. The posterior temporal flap is a simply, reliable procedure, with low morbidity. This technique is probably the procedure of choice in discal replacement and in interposition arthroplasty for ankylosis.

[Entropion: therapeutic indications].

The severity of entropion depends on trichiasis which is perpetuated by orbicularis spasm, creating a vicious cycle. The therapeutic approaches are based on the aetiopathogenesis. Congenital entropion is essentially treated by infraciliary cutaneomuscular resection. The various components of involutional (senile) entropion, horizontal and vertical retraction, orbicularis dyskinesia, are treated respectively by tissue reduction, reinforcement of retractore and myoplasties. In cicatricial entropion, chondro-mucosal or fibromuscular graft is the technique of choice for correcting insufficiency of the tarsoconjunctival plane or its curvature. It is also the best solution for the correction of trichiasis or distichiasis.

[Orbital hydatid cyst. Apropos of 2 cases].

Orbital hydatid cysts are extremely rare in France. The authors report two cases in young adults of North African origin, one being a recurrence. Echography and CT scan were the most useful paraclinical investigations. The cysts were surgically excised with difficulty via an anterior approach adapted to the localisation. After 5 years follow up, both patients survived, however, there was major visual loss (blindness, or requirement for enucleation), due to the delay in diagnosis.

[Repair of mutilations of the lacrimal apparatus].

Repair of mutilated lacrimal passages should be adapted to the anatomy and physiology. Whenever possible, this should be performed as an emergent operation and come in as part of an overall therapeutic strategy. Repair methods used are simple end-to-end approximation of permeable segments, in case of limited lesions, and use of arterial grafts or of adjacent, nasal or saccular mucous flaps, in case of extended lesions. When reconstruction is not feasible owing to the extent of the lesions or to failure of the repair methods, tear derivation is carried out directly via the lacrimal sac or nasal fossa, by means of intermediate flaps (primarily nasal mucosa) or indwelling drains. Objectively, the functional outcome of repair is hard to assess, as tearing can, by no means, be considered a clinical criterion of obstruction, in the same way as lack of tearing is not a criterion of permeability. Only dacryography or, when possible, postoperative scintigraphy of the lacrimal passages allow for an objective evaluation of the results. Thus, although satisfactory results are the rule, long-term objective observation often leads to mitigating feelings.
