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 preoperatively
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.Major post-operative complications did not occur in either group. In
the group A, one patient developed temporary facial nerve palsy which
improved after three months.
All recurrent patients in group A were retreated by doing eminectomy
with follow up period (6- 16) months with a mean of (10.1± 6.3) months
which be group C.
There were limitations in this study that we did not make an
arthroscopic eminoplasty in group A and made eminoplasty by an open
surgery due to logistics reason, the second limitation was the small sample
size of the study especially in the male patients.
Within the limitations on the current study we can conclude that the
eminectomy is a well established treatment modality with a good success
rate and low morbidity in treatment of chronic recurrent TMJ dislocation.
