Management of temporomandibular joint dislocation at mayo hospital Lahore

ABSTRACT

For the management of TMJ dislocation, controversies always surround to the various conservative and surgical modalities. Hence a retrospective study was planned to audit the demographics, etiology and patterns of occurrence and to enumerate the treatment modalities of TMJ dislocation at the De-partment of Oral and Maxillofacial Surgery/Mayo Hospital Lahore, fifty two cases of TMJ dislocation were retrospectively studied from 2013 to 2017. Patient records contained information about age, sex, type of dislocation, immediate event preceding the dislocation, treatment modality used and reported complications regarding dislocation. Thirty two patients [62%] were males and 20 [38%] were females. Their ages ranged from 1-80 years with a mean of 37 years. 23/52 patients were presented with acute dislocation which were managed by manual reduction and analgesics. 19/52 patients were presented with chronic recurrent dislocation in which 7 patients were injected with autologous blood, 9 patients were treated with intermaxillary fixation and three patients were given STD injection. Chronic long standing TMJ dislocation in 10 patients were managed by eminectomy in 7 patients and condylecto-my in 3 patients. This study concluded that male sex, middle age, yawning, and low socio-economic status appeared to be associated with TMJ dislocation; however, this observed relationship was not statistically significant. Different treatment modalities exist. This study highlighted the advantages and effectiveness of conservative methods of treatment
