Which of the following statements is a reason for a patient needing a fenestration surgery to restore their hearing?  

• A. To bypass the cochlea and vestibular apparatus to access the inner ear. 
• B. To bypass the stapes bones in the creation of a new opening into the inner ear.  
• C. To create a new opening in the auditory canal to gain access to the inner ear. 
• D. To act as an emulsifier to cerumen. 

Answer: (B)

Verified step by step guidance

1. Step 1: Understand what fenestration surgery is — it is a surgical procedure designed to improve hearing by creating a new opening (fenestra) in the inner ear structures.
2. Step 2: Identify the anatomical structures involved in hearing, focusing on the middle ear bones (ossicles), especially the stapes, which transmits sound vibrations to the inner ear.
3. Step 3: Recognize that fenestration surgery aims to bypass a damaged or immobilized stapes bone, which can cause conductive hearing loss by preventing sound transmission.
4. Step 4: Evaluate each statement by comparing it to the purpose of fenestration surgery: the correct reason involves bypassing the stapes bone to create a new opening into the inner ear.
5. Step 5: Conclude that the correct statement is the one describing the bypass of the stapes bone through the creation of a new opening, as this directly relates to restoring hearing by allowing sound waves to reach the inner ear.
