Microtia

Microtia is when the external ear and other structures of the outer, middle, and sometimes inner ear are underdeveloped. Microtia refers to the external ear deformity which is congential.
Microtia is when the external ear and other structures of the outer, middle, and sometimes inner ear are underdeveloped. Microtia refers to the external ear deformity which is congential.

There are four grades of microtia:


  • Grade 1: A less than complete development of the external ear with identifiable structures and a small but present external ear canal.

  • Grade 2: A partially developed ear with artresia or a closed stenotic external ear canal producing a conductive hearing loss.

  • Grade 3: The most common form of microtia. Absence of the external ear canal.

  • Grade 4: Absence of the total ear or anotia.

Is it possible to perform a surgery on an external ear and an ear canal simultineosly?

Dr. Ashesh Bhumkar, whose interests are presented by the Impex life project in Russia, owns a unique technology for the simultaneous atresia release of the ear canal and the ear plastic.


The first surgery was performed in America in January 2008 by Dr. Joseph Robertson and Dr. John Reinish.

To perform this type of operation, Professor Ashesh Bhumkar and his colleagues study additional factors in determining the candidate for surgery.

There are two main approaches to the outer ear reconstruction. One of the methods is to use a transplantate patient’s autologous rib. The other approach in surgery is to use porous polyethylene (known as Medpor) instead of the rib. Surgical reconstruction of Medpor can be carried out with the minimum age of 3 years and above. Medpor is installed in one operation, but in some cases, additional minor surgery is required. The use of Medpor is carried out only after the atresia release. One-stage operation is possible when the doctor performs a surgery to eliminate atresia together with a plastic surgeon who installs Medpor.

Why is surgical release of atresia recommended before Medpor?

There will be more complications if Medpor is performed before the surgical release of atresia of the ear canal. Since the work of the plastic surgeon is done superficially, he is not able to determine where the canal should be placed in relation to the patient’s middle ear.
