Question

A 20-year-old patient presents with recurrent ear discharge. On otoscopic examination, the examiner notes complete absence of tympanic membrane. What is the best option for treatment?

• A. Myringoplasty
• B. Radical mastoidectomy
• C. Ossiculoplasty
• D. Tympanoplasty

Hint:

Tympanoplasty repairs tympanic membrane and may also reconstruct ossicles if needed.

Answer 1

The Correct Option is D

Step 1: Understanding the Question:
The case involves a patient with chronic ear disease and a total loss of the tympanic membrane. We must select the most comprehensive surgical reconstruction method.
Step 2: Definitions of Surgical Terms:

Myringoplasty: Closure of a tympanic membrane perforation without middle ear exploration.

Tympanoplasty: Reconstruction of the tympanic membrane with exploration of the middle ear and potential repair of the hearing mechanism.

Step 3: Detailed Explanation:

Surgical Rationale: In a case described as "complete absence" of the tympanic membrane, the middle ear has been exposed to the environment and recurrent infections for a significant period. A simple myringoplasty (A) is often inadequate because the surgeon must inspect the middle ear mucosa and the integrity of the ossicular chain, which is best achieved via a formal Tympanoplasty.

Tympanoplasty Types: A Type I Tympanoplasty is used to repair the tympanic membrane when the ossicles are healthy. For a total perforation, a large graft (usually temporalis fascia or perichondrium) is used to create a new drum.

Radical Mastoidectomy (B): This is an aggressive procedure that removes the drum and ossicles to create a common cavity, used for extensive cholesteatoma or malignancy. It is not indicated for a simple absence of the TM.

Ossiculoplasty (C): This addresses only the bones of hearing. While it might be performed alongside a tympanoplasty, it does not solve the primary problem of the missing ear drum.

Therapeutic Goal: The goal of Tympanoplasty in this 20-year-old is to provide a "dry" ear and reconstruct the sound-conducting mechanism to improve hearing.

Step 4: Final Answer:
The best option for reconstructing the ear when the tympanic membrane is completely absent is Tympanoplasty.
