Type ‘C’ tympanogram is seen in
**Question:** Type 'C' tympanogram is seen in
A. Normal
B. Mixed type
C. Flat
D. Bronchogenic carcinoma
**Core Concept:**
Tympanogram is a test that measures the compliance and impedance of the middle ear using a special device called a tympanometer. The results can be classified into three types: Type A, Type B, and Type C.
**Why the Correct Answer is Right:**
Type C tympanogram is seen in cases where the middle ear is filled with fluid, such as in otitis media with effusion (OME), also known as glue ear. In such cases, the compliance of the middle ear is significantly reduced, leading to a Type C tympanogram.
**Why Each Wrong Option is Incorrect:**
A. Type A tympanogram is normal and does not represent a condition.
B. Type B tympanogram is seen in cases of air-filled middle ear, not fluid.
C. Type D tympanogram is associated with bronchogenic carcinoma, which is a lung cancer and not related to middle ear conditions.
**Clinical Pearl:**
Type C tympanogram is a clinical sign of otitis media with effusion. Early diagnosis and management of this condition are crucial as it can lead to hearing loss and speech development issues in pediatric patients.
**Correct Answer:**
**D.** Type C tympanogram
Type C tympanogram represents a condition where the middle ear is filled with fluid, such as in otitis media with effusion (OME), also known as glue ear. This type of tympanogram demonstrates reduced compliance of the middle ear due to the presence of fluid, which can lead to hearing loss and speech development issues if left untreated, especially in pediatric patients.
