<div>Abstract Objectives: This study aimed to determine success rate of
tympanoplasty in CSOM patients &amp; its prognosticating factors. Design
and setting; A facility based retrospective cross sectional study design
was employed to assess the characteristics of chronic suppurative otitis
media patients and the success rate of tympanoplasty of patient who
underwent surgery at ORL-HNS of SPHMMC, Addis Ababa, Ethiopia. Methods:
Ninety patients who had undergone tympanoplasty in the year 2019 from a
retrospective database were studied. Data was collected using a
structured checklist and analysed using SPSS 25. Baseline profiles of
participants were computed using descriptive statistics. Paired t-test
was used to compare preoperative and postoperative ABG results. Multiple
regression analyses of potential factors (intra-&amp; pre-operative
characteristics) were used to identify predictors for success of
tympanoplasty while the level of significance was set at
p&lt;0.05. Anatomical success was defined as a complete
integration of the graft and functional success as an ABG closure of
≤20dB after 6 months postoperatvely. Results: The postoperative
anatomical &amp; functional success rates for tympanoplasty were 81.1% and
60%, respectively. According to the statistical results of the study,
neither the anatomic success nor the functional was found to be
prognosticated by the potential factors analyzed. Conclusion:
Tympanoplasty is an effective surgical procedure that can result in
improved auditory function in patients and prevents complications
satisfactorily irrespective of baseline characteristics. With
tympanoplasty, the ear heals and the patient hears. Keywords:
