Abstract
Introduction Myringoplasty is a commonly performed otologic surgery.
Objectives The objective of this study is to evaluate the effect of prognostic factors like
- size, site of perforation, status of operating ear, approach, status of contralateral
ear, experience of surgeon, primary or revision myringoplasty, and smoking in graft
uptake, as well as to evaluate the hearing results after myringoplasty.
Methods This is a prospective study. We included in our sample patients aged over 13 years
with a Tubotympanic Chronic Otitis Media diagnosis. The patients underwent preoperative
evaluation and Pure Tone Audiogram within one week prior to surgery. We performed
myringoplasty using temporalis fascia graft with conventional underlay technique.
We evaluated postoperative graft uptake and various factors related to the study and
did a Pure Tone Audiogram at one year after surgery.
Results The graft uptake rate after myringoplasty was 83.1% at one year in 219 patients.
Graft uptake with normal opposite ear was 88.2%, and with Tubotympanic Chronic Otitis
Media was 75% (statistically significant). We found no statistically significant difference
in graft uptake results with other factors. We calculated hearing results of 132 patients
with normal ossicular status who underwent myringoplasty. The average Air Conduction
Threshold improvement was 11.44dB (p < 0.001) and the average Air-Bone Gap closure was 8.89dB, highly statistically significant
(p < 0.001).
Conclusion Diseased contralateral ear was a statistically significant poor prognostic factor
for graft uptake after myringoplasty. Other factors studied were not statistically
significant determining factor for graft uptake. Hearing improves significantly after
myringoplasty if the ossicles are normal.
