Abstract
The study presents six hundred ear operations of varied middle ear pathology using tragal cartilage and perichondrium as a choice graft. The technical advantages of tragal perichondrium graft in myringoplasty, ossiculoplasty, ossiousplasty, and mastoid cavity obliteration are discussed.
KEM Hospital
The study was conducted at K.E.M. Hospital, ENT department during 1980 to 2000. we have recorded our observations and results and concluded that tragal perichondrium and cartilage is an ideal graft material for reconstructive tympanoplasty. The objective of study was to assess the efficacy of tragal perichondrium and cartilage, the functional capacity in restoring hearing acuity, it’s mechanical survival, it’s extrusion rate and it’s functional integrity in tympanomastoid reconstruction.
Keywords: Cartilage, Perichondrium, Sialastic.
Introduction
Internal Ear
The technique of ‘Reconstructive Tympanoplasty’ has been improved and refined ever since the introduction of operative microscope. The methods of radical and modified radical mastoid operations have not changed for decades except for minor variations. The innumerable graft materials being used to restore the dry and functioning ear. The autologous, homologous and allograft, synthetic materials lik plastics, ceramics, hydroxyapatite and golds were used but none of these have established their universal acceptability as a proved graft except the autologous grafts (cartilage, ossicles, fascia). The functioning and survival of each graft material varies as each one has certain advantages ad disadvantages and technical problems during and after surgery.
