Abstract
Background and aimChronic otitis media is defined as a chronic inflammation of the middle ear cleft producing irreversible pathological changes. The myringoplasty aims at the reconstruction of the tympanic membrane using a graft material. Autologous platelet-rich plasma can be used along with the graft to have a successful outcome. The aim of the study was to assess the efficacy of autologous platelet-rich plasma on graft uptake in myringoplasty.MethodsThis was a randomized controlled trial with a sample size of 76 patients. All patients were above 18 and below 55 years of age diagnosed with chronic suppurative otitis media and were planned for myringoplasty. The participants were randomly allotted to two groups by block randomization (block of 4). Intra-operatively, group I (n=38) received platelet-rich plasma–soaked gel foam and group II (n=38) was taken as the control group who received saline-soaked gel foam and examined by a blinded examiner at the end of 1st and 3rd months.ResultsThe mean air-bone gap reduction post-operatively in the platelet-rich plasma group was 8.68 ± 4.8 (P value 0.034) and 6.05 ± 4.05 in the control group. The improvement in pure-tone average in the platelet-rich plasma group (P = 0.009) is more than that in the control group. The graft uptake was higher among the platelet-rich plasma group than the control group both at 1st and 3rd months (P value 0.049) which were statistically significant.ConclusionThe present study concludes that the usage of platelet-rich plasma in the conventional myringoplasty technique has improved the success rate of graft uptake and reduced the graft migration.Trial registrationClinical Trials Registry-India (ICMR-NIMS) CTRI/2020/04/024416.

Background and aimChronic otitis media is defined as a chronic inflammation of the middle ear cleft producing irreversible pathological changes
The present study was conducted with the aim to assess the efficacy of autologous platelet-rich plasma on graft uptake in myringoplasty which yield significant mean reduction in the air-bone gap, improvement in pure-tone average, graft uptake, and percentage of closure after surgery which was higher in the PRP group when compared to the control group
The present study showed that nearly 97.4% (37) had graft uptake at 1st month in the PRP group, which is higher than the control group, which had only 89.5% graft uptake
