title: [Drill decompression-spongiosaplasty of the temporomandibular joint. A preliminary study of various temporomandibular dysfunctions].
abstract: Long follow-up in TMJ patients shows often a lack of success with a recurrence of pain. To lower the rate of failures or at least partial failures, the relative positions between mandibular condyle and glenoïd fossa were studied, in case of recurrence after TMJ occlusal and surgical treatment: asymmetry was found between both sides. Sometimes the mandibular head is in a low and anterior position (in absence of major occlusal disorder): we call this "stretching syndrome" (for posterior apparatus). Patients complain of jaw instability. Sometimes the mandibular head is in a very high and posterior situation: we call this "compressive syndrome". In this case, patients complain of a recurrence of pain (generally the clicking disappeared after the first TMJ surgery). We propose in "stretching syndrome" to treat the instability by a cartilaginous graft, and in "compressive syndrome" to decompress the bone by drill tunnel with external effect (secondary bone settles down) and internal effect (venous drainage and oedema decrease). First results are good with a high healing rate, but the follow-up is not long enough to a complete assessment of this technic.
