A type 1 tympanoplasty is synonymous to myringoplasty. Type 2 involves repair of the tympanic membrane and middle ear in spite of slight defects in the middle ear ossicles . Type 3 involves removal of ossicles and epitympanum when there are large defects of the malleus and incus.

The eardrum comprises two parts: the pars tensa, which is the main part of the eardrum, and the pars flaccida, which is a smaller part of the eardrum located above the pars tensa.
Otoplasty (surgery of the ear) was developed in ancient India and is described in the medical compendium, the Sushruta Samhita (Sushruta's Compendium, c. 500 AD).The book discussed otoplastic and other plastic surgery techniques and procedures for correcting, repairing and reconstructing ears, noses, lips, and genitalia that were amputated as criminal, religious, and military punishments.
