Abstract:
Purpose: This study assesses the effectiveness of eminectomy in the management of chronic closed lock, refractory
to conservative medical management in the largest multicentred study of its kind in the UK, with a cohort of 167
patients. Temporomandibular mandibular joint disorder
affects 30% of adults in the UK. Chronic closed lock is a
well-documented sub-type.
Method: A retrospective study of patients with refractory
closed lock was carried out, where conservative management had been implemented for a minimum of 6 months.
Refractory patients were offered eminectomy at three
separate centres over a period from 1995 to 2011. The
primary variable was the inter-incisal distance (IID). Other
variables included pain, clicking and nerve damage preand post-operatively.
Results: There were 167 patients across all three centres,
81% of which were female. The mean IID was 23 mm preoperatively and 37 mm post-operatively. There was a statistically significant association with the primary predictor
variable, yielding a p value of \ 0.05. Clicking resolved
completely post-operatively in 84 patients (58%). Pain
subjectively improved in 56% cases. Conclusion: Eminectomy is a safe and effective surgical
procedure and has a role to play as a second-line surgicaloption in the management of closed lock after more conservative medical options have failed.
