Tympanic membrane perforations.

The recent literature on the healing of tympanic membrane perforations is reviewed. Research on the migratory phenomena, epithelial migration and keratin dispersion on top of the tympanic membrane, is discussed. The etiology and pathogenesis of tympanic membrane perforations is then briefly described. The literature on the healing process of tympanic membrane on animal experiments as well as observations in humans is amply discussed. Finally different non invasive and or office procedures for tympanic membrane repair are reported.
