مستخلص: Tympanic membrane perforations are due to common otologic problems. The current treatments to heal tympanic membrane perforation, such as myringoplasty, have some disadvantages, including the need for autologous grafting, which is rapidly absorbed by the organism before perforation recovery is complete. To improve the structural and functional tympanic membrane healing after surgery, we propose a new branch of artificial grafts. In this study, we report the development of artificial grafts using electrospun bioabsorbable polymers. Polymers such as poly (l-lactic acid) and poly (lactic-co-glycolic acid) acted as the scaffold for cell growth in a co-culture of fibroblasts and keratinocytes. This co-culture promoted the growth of an epithelial-equivalent tissue over the electrospun scaffold, which was used as an alternative graft in myringoplasty. The in vivo study was performed in Sprague Dawley rats. Ear endoscopy was performed 30days after surgery and showed that tympanic membrane perforations treated with artificial grafts healed naturally, completely and with the possibility of maintaining their actual functionality. In conclusion, our study described a new artificial graft created specifically to fulfill the requirements of perforated tympanic membrane healing processes, which are compatibility, proper durability and less intense side effects following myringoplasty.
