Research Objective
The primary objective of this study is to evaluate the audiological outcomes following
type I tympanoplasty in patients diagnosed with chronic otitis media (COM). The study aims
to determine the degree of hearing improvement post-surgery and to analyze the success rate of
tympanic membrane graft uptake based on the type of graft material used. The primary
objective of this study is to conduct a comprehensive evaluation of the audiological outcomes
in patients diagnosed with mucosal-type chronic otitis media (COM) following Type I
tympanoplasty. Specifically, the research aims to assess the degree of improvement in hearing
function by comparing preoperative and postoperative audiometric data, with an emphasis on
the air-bone gap (ABG). In addition, the study seeks to analyze the anatomical success of
tympanic membrane grafting by evaluating the graft uptake rate in relation to the type of graft
material used (temporalis fascia versus tragal perichondrium). Secondary objectives include the
identification of potential factors that may influence surgical outcomes, such as the size and
location of the perforation, the duration of otorrhea-free periods, and intraoperative technical
variations. Through this multidimensional analysis, the research endeavors to enhance
evidence-based surgical planning and improve patient outcomes in the management of chronic
otitis media.
Materials and Methods
This prospective study was conducted on 36 patients (aged 18–60) with mucosal-type
chronic otitis media undergoing type I tympanoplasty at Samarkand State Medical University.
Inclusion Criteria:
- Chronic otitis media with conductive hearing loss
- Dry ear for ≥4 weeks preoperatively
Exclusion Criteria:

- Presence of cholesteatoma or ossicular chain pathology
- Previous ear surgeries
Surgical Technique:
- Underlay tympanoplasty technique under general anesthesia
- Graft materials: temporalis fascia (n=24) and tragal perichondrium (n=12)
Audiological Assessment:
- Pure-tone audiometry (PTA) pre- and postoperatively
- Air-Bone Gap (ABG) measured and compared
Results
Of the 36 patients:
- Temporalis fascia was used in 24, tragal perichondrium in 12
- Graft uptake success rate: 91.6%
- Mean ABG decreased from 32.4 ± 5.1 dB preoperatively to 15.2 ± 4.3 dB
postoperatively (p < 0.001)
- No major complications were recorded
Discussion
Tympanoplasty remains the standard surgical approach for the treatment of tympanic
membrane perforations in chronic otitis media. Both temporalis fascia and tragal perichondrium
demonstrated high graft acceptance and audiological improvement. The temporalis fascia group
exhibited slightly better audiological outcomes, though the difference was not statistically
significant. Success factors include meticulous surgical technique, appropriate patient selection,
and adequate postoperative care.
Conclusion
Tympanoplasty is a reliable and effective method for improving hearing in chronic otitis
media patients. Both temporalis fascia and tragal perichondrium serve as suitable graft
materials. The procedure demonstrates high graft uptake rates and significant hearing
improvement, supporting its continued use in otologic surgery. This study demonstrates that
Type I tympanoplasty is an effective and reliable surgical technique for managing mucosal-
type chronic otitis media, with high rates of graft success and significant audiological
improvement. The postoperative reduction in the air-bone gap validates the functional
restoration of hearing, and the high graft uptake rate underscores the anatomical success of the
procedure.

Both temporalis fascia and tragal perichondrium proved to be viable graft materials,
although a slight audiological advantage was observed with temporalis fascia. Moreover,
patient selection, preoperative ear condition, and meticulous surgical technique are key
determinants in ensuring favorable outcomes. The absence of major complications further
confirms the safety and feasibility of tympanoplasty. These findings contribute to the growing
div of evidence supporting tympanoplasty as a gold-standard intervention and provide
valuable insights that may guide clinical decision-making and surgical optimization in otologic
practice.
