In the stable perforation of tympanic membrane , if there isn’t infection in the tympanic cavity , the paper patch or myringoplasty may be used. These procedures need remedy charge and time and may be with morbidity and other complications. Recently materials like hyaluronic acid and epidermal growth factors has been used to speed healing of tympanic membrane perforation, and their effect has been proved. Pentoxifylline an anti-thrombotic drug has positive effect on increasing perfusion and wound healing in pathological conditions. Alike we have used pentoxifylline to show it’s effect on the healing of guinea pig perforated tympanic membrane.

Materials and Methods: This study has been done prospectively, on 32 guinea pig ears.
