Abstract
Chronic recurrent TMJ dislocation one of the worth TMJ disorder that harass the patient life with inability to close the mouth, mentalis protrusion, tension and spasms of mastication muscles, excessive salivation, difficulty in phonation and pain in the TMJ region44,128
The aim of this study was clinically compared between eminectomy and eminoplasty in treatment of chronic recurrent dislocation of TMJ by assessment of recurrence of dislocation, mouth opening and severity of pain.
In the present study 13 patients with an age range of (22-55) year with a mean of (32 ± 8.3) year diagnosed with bilateral chronic recurrent TMJ dislocation where randomly assigned in two groups, first group included six patients treated by eminoplasty with removing of anterior lateral slope of eminence and the control group including seven patients treated by complete removing of eminence. All patients did multislice CT scan pre-operatively to exclude any pneumatization of the eminence.
The follow up period post-operatively ranged from (11- 36 months) for all patients with a mean of (20.2± 7.9) months.
Immediately post-operatively there was a decrease in the maximum mouth opening in both group with a mean of (33.1 ± 0.6) mm in the eminoplasty group (A) and a mean of (32.8 ± 0.26) mm in eminectomy group (B) that were improved gradually after three and six months follow up to reach (40.8 ±0.4) mm in eminoplasty group (A) and (40.4 ± 0.48) mm in eminectomy group (B).
In the first six months of the study we found that there was no recurrence in both groups post-operatively but after that all female patients in eminoplasty group (A) showed recurrence.
