Which of the following statement regarding Eustachian dysfunction is wrong?
- A.
Undistorted light image on the anterior quadrant of tympanic membrane
- B.
No movement of the tympanic membrane on Sengul's method
- C.
Malleus is easily visible
- D.
Lusterless tympaic membrane
Correct Answer
A. Undistorted light image on the anterior quadrant of tympanic membraneExplanation
The statement "Undistorted light image on the anterior quadrant of tympanic membrane" is incorrect. In cases of Eustachian dysfunction, there may be a distorted or blurred light image on the anterior quadrant of the tympanic membrane due to fluid accumulation or pressure changes in the middle ear. This can affect the ability of the Eustachian tube to equalize pressure and can lead to symptoms such as hearing loss or ear pain.Rate this question:

In Acoustic neuroma, the following is not seen
- A.
Auditory defect
- B.
Sensory aphasia
- C.
Motor aphasia
- D.
Changes in Audimetry
Correct Answer
C. Motor aphasiaExplanation
Motor aphasia is not seen in acoustic neuroma. Acoustic neuroma is a benign tumor that develops on the vestibulocochlear nerve, which is responsible for transmitting sound and balance information from the inner ear to the brain. It typically causes symptoms such as hearing loss, tinnitus, dizziness, and balance problems. Sensory aphasia refers to difficulty in understanding and expressing language, while motor aphasia refers to difficulty in speaking or articulating words. Although acoustic neuroma can affect the auditory system and cause auditory defects and changes in audimetry, it does not typically cause motor aphasia.Rate this question:

Commonest indication for myringotomy is
- A.
Myringitis bullosa
- B.
Serous otitis media
- C.
Middle ear defect
- D.
Mastoiditis
Correct Answer
B. Serous otitis mediaExplanation
Serous otitis media is the most common indication for myringotomy. Serous otitis media refers to the accumulation of fluid in the middle ear without signs of infection. This condition often occurs after an upper respiratory tract infection and can cause hearing loss and discomfort. Myringotomy involves making a small incision in the eardrum to drain the fluid and relieve pressure. It is a common surgical intervention for serous otitis media to improve hearing and prevent complications.Rate this question:

Correct Answer
C. Autosomal dominant in femalesExplanation
Otosclerosis is a condition characterized by abnormal bone growth in the middle ear, leading to hearing loss. The correct statement is "Autosomal dominant in females." This means that the gene mutation responsible for otosclerosis is located on an autosome (non-sex chromosome) and only one copy of the mutated gene is needed for the condition to be expressed. Additionally, the condition is more commonly seen in females than in males.Rate this question:
