Evaluate the efficacy of a photocrosslinkable gel patch for repairing tympanic membrane (TM) perforations using a minimally invasive procedure

A novel gel patch for minimally invasive repair of tympanic membrane perforations.

Article specifications

This clinical trial was published in 2018 in Journal of Int J Pediatr Otorhinolaryngol. (IF 2015: 1.125) by American specialists. The aim of this study was Evaluate the efficacy of a photocrosslinkable gel patch for repairing tympanic membrane (TM) perforations using a minimally invasive procedure. 38 adult male chinchillas underwent bilateral TM perforation via CO2 laser (n = 76 TMs). Eight weeks post-perforation induction, either a gel patch (n = 26) or EpiDisc (n = 12) was applied to the perforation through the ear canal.

 

Result

The gel is promising regarding thickness and trilaminar regenerated tissue, perhaps due to the biomechanical properties of the gel, and further refinements in the material and technique are anticipated to increase ease and efficacy of treatment while minimizing complications.
