ABSTRACT
Objective@#To investigate the treatment methods of chronic prolonged mandibular dislocation.@*Methods@#Surgical reduction was performed in a case of temporomandibular joint dislocation over 6 months after manual reduction failure. The flap was removed under general anesthesia, and the bone of the condyle were removed. The articular disc was aligned and incision was sutured, and the procedure was combined with intermaxillary fixation for a correct occlusion and traction. After the operation, the surgical efficacy was observed, and the related literature was reviewed. @*Results@#The patient recovered well after the operation; the mouth opening was 3 cm, and the occlusion was normal. No recurrence was observed after 10 months of follow-up. The literature shows that surgery is a common treatment for temporomandibular joint dislocation after the failure of manual reduction, and postoperative patient education can reduce recurrence and complications. @*Conclusion @#Surgery combined with intermaxillary traction can effectively treat chronic prolonged mandibular dislocation.
ABSTRACT
Temporomandibular joint (TMJ) recurrent dislocation is usually associated with jaw hypermobility or articular eminence anatomy. Patients who have stroke experience (CVA) can present joint and muscle tone changes, as laxity ligamentous and appearance of spastic muscle patterns in different parts of the body such as shoulder, elbow, wrist, hip, knee and face. This study reported two cases of patients with stroke sequelae who developed chronic dislocation of the jaw. It was concluded that these two clinical conditions appear to have some correlation, further studies with more patients needed to confirm this correlation.
A luxação recorrente da articulação temporo-mandibular ocorre quando o côndilo mandibular move-se para fora da cavidade glenóide e permanece travado anteriormente à eminência articular de forma repetitiva. Pacientes com histórico de acidente vascular cerebral podem apresentar alterações articulares e de tonicidade muscular. O presente estudo relatou dois casos clínicos de pacientes com seqüela de AVC, que desenvolveram luxação crônica da mandíbula. Concluiu-se que essas duas condições clinicas parecem apresentar alguma correlação clínica, sendo ainda necessário estudos com mais pacientes para confirmar tal correlação.
ABSTRACT
5 patients with chronic prolonged mandibular dislocations(CPMD)were examined by CT scan.The patients were treated by manual reduction under general anaesthesia and muscle relaxants.Traction was performed with ligaturing steel wires on fixation titanium screws intermaxillaryly and wrapping up the skull-jaw bone with elastic bandages for 3 weeks.After 1 month,a maximal mouth opening of o-ver 30 mm was noted and no episode of redislocation occurred in 3 -34 month follow-up.
