Abstract

Background and objectives: Chronic Suppurative Otitis Media (CSOM) is one of the
most common ear diseases in South East Asia having a prevalence of approximately
5.2% in the general population.Cartilage material is criticized in terms of hearing
results due to its thickness. The objective of this study was to evaluate the effectiveness
of cartilage as grafting material in terms of graft uptake and post-operative hearing
following Type-I tympanoplasty.
Materials and methods: All patients undergoing Tympanoplasty in Govt. ENT Hospital,
Osmania Medical College, Hyderabad, who comply with inclusion and exclusion
criteria, and who were diagnosed as Tubotympanic type of chronic suppurative otitis
media and were taken up for Type-I Tympanoplasty were included in the present study
for a period of one and half years from November 2015 to June 2017. 50 subjects were
enrolled and Subjects were reviewed on 8thpost-operative day, 6thand 12thpost-operative
weeks. The graft uptake and post-operative hearing were evaluated.
Results: The graft uptake on 6thand 12thpost-operative weeks was 87.7% & 86.6%
respectively. The difference of means of air bone gaps for pre-operative, 6th postoperative
week and 12thpost-operative week were 30.11 ± 1.66 dB, 18 ± 1.50 dB, 15.86 ±
1.50 dB respectively.The results were statistically significant, showing improvement in
hearing after surgery. On 12thpost-operative week 5 subjects had no hearing gain.
Closure of air-bone gap within 30 dB was achieved in 81.10% subjects.
Conclusion: The cartilage was found to be excellent grafting material in terms of both
the graft uptake rates and hearing results after type 1 tympanoplasty.
