Abstract
Background Tympanoplasty is the well-established procedure for closure of perforations of tympanic
membrane.
Study Design This study was a prospective comparative study.
Objective The objective of this study was to compare the hearing improvement and graft uptake
rate between dry and wet tympanoplasty performed on tubotympanic type of chronic suppurative
otitis media.
Materials and Methods One hundred forty patients with tubotympanic type of chronic otitis media were selected
and categorized into dry and wet ears. Tympanoplasty was performed using temporalis
fascia by underlay technique in all cases. Postoperatively, graft uptake rate and
hearing improvement were analyzed.
Results The graft uptake rate was equal in both dry and wet ears, which was statistically
insignificant. There was no statistically significant difference in the hearing improvement
between the dry ears and wet ears (χ – 2.39, p = 0.122).
Conclusion Factors such as age, sex, and status of the contralateral ear and wet ear did not
have any impact on the postoperative graft uptake of tympanoplasty. There was no difference
in the graft uptake between the dry and wet ears and there was no statistically significant
difference between hearing improvement in both and wet ears.
