Comparing the effects of local vitamin A and local dexamethasone on preventing myringosclerosis in human tympanic mem‑
branes caused by ventilation tubes was the aim of the study. Three groups were created from 90 kids having myringotomies
and ventilation tube insertions: In group I, thirty children are undergoing myringotomy and the insertion of a ventilation tube
alone; in group II, thirty children are undergoing myringotomy and the insertion of a ventilation tube along with the use of
local vitamin A; and in group III, thirty children are undergoing myringotomy and the insertion of a ventilation tube along
with the use of local dexamethasone. According to otoscopic and microscopic examination, group 2 (6 ears) that received
local vitamin A had a lower incidence of myringosclerosis than group 3 (11 ears) that received local dexamethasone and
group 1 (21 ears) that did not receive any local medication. According to the study's findings, local vitamin A is more effec‑
tive than local dexamethasone at reducing the severity and incidence of myringosclerosis in children having myringotomy
and ventilation tube insertion.
