Aim: The aim of the study is to compare the results of myringoplasty performed using
temporalis fascia with that of tragal perichondrium.
Methodology: A Hospital based prospective study was conducted to compare the
success rate of myringoplasty performed with temporalis fascia versus tragal
perichondrial grafting at department of ENT,Govt ENT Hospital,Koti,Hyderabad..
Patients with chronic suppurative otitis media with tubo tympanic type were included
in the study.
Results: A total of 60 patients were studied among which 30 were in group A and 30 in
group B. Patients were diagnosed by clinical examination and otomicroscopy. Pre
operative hearing evaluation was done by pure tone audiometry. Myringoplasty was
performed using temporalis fascia and tragal perichondrium in group A and group B
respectively. Follow up was done at 3 weeks, 6 weeks, 3 months and at 6 months post
operatively. During the follow up, patients were assessed for graft uptake and hearing
improvement and the results were compared between both the groups. The results were
as follows: Age of pts was between 15- 60 yrs with majority between 20 to 40yrs. There
were a total of 33 males and 27 females. Right ear was operated in 33 patients and left
ear in 27 patients. A total of 14 cases were operated with presence of bilateral disease
(6:8). Overall graft uptake rate was 85%. Graft uptake rate was 83.33% with
temporalis fascia and 86.66% with tragal perichondrium. Mean improvement in
hearing for temporalis fascia was 9.81 ± 5.10 dB and for tragal perichondrium was 8.42
± 4.10 dB.
Conclusion: It is concluded that graft material does not influence the either graft uptake
or hearing improvement in safe type of CSOM when conductive hearing loss is less than
40 db and in the absence of central pathology and tympanosclerosis.
