Aim:
To evaluate the hearing changes following stapedotomy surgery,
and to investigate the potential effects of the age and sex of the
patients on air-bone gap closure.
Material and Methods:
80 patients diagnosed with otosclerosis and undergone
stapedotomy surgery, were involved in this study. The hearing changes were evaluated by comparing the means of air and bone conductive measurements at 250-500-1000-2000 and 4000 Hz before and after surgery. In addition, the air-bone gap closure was determined. Data was analysed statistically using t-student and Anova tests (p=0.05).
Results:
There was a statistically significant difference in air conductive
measurements before and after surgery (p<0.001), whilst the bone
conductive values showed no differences. The mean of air-bone
closure in the current study was 28.6dB.
Aim:
To evaluate and compare the rate of cholesteatoma recurrence after Atticotomy surgery to that after Canal Wall Up Mastoidectomy (CWU).
Material and Methods:
The study involved 57 patients admitted to the ENT Department Almoassat Hospital. A
tticotomy was performed in 30 cases, whilst CWU mastoidectomy within 27 cases. Follow up period was extended for two years to compare the symptoms and the necessity for second Ossiculoplasty surgery.
Results:
The recurrence rate was 23.33 % within atticotomy group, whilst it was 22.21 % in CWU group. CWU mastoidectomy showed better outputs in diffused cholesteatoma cases.
Conclusion:
A limited cystic cholesteatoma can be treated effectively by atticotomy, however CWU mastoidectomy remains the favorable technique to manage a diffused cholesteatoma.
