Bronchophony[edit]
Bronchophony is a clinical sign used in the assessment of the respiratory system. It refers to the increased clarity and resonance of the voice sounds heard through a stethoscope over the lung fields. This phenomenon is typically assessed during a physical examination when a patient is asked to repeat a phrase, such as "ninety-nine," while the examiner listens with a stethoscope.
Mechanism[edit]
Bronchophony occurs when there is increased transmission of sound through the lung tissue. Normally, the lung tissue acts as a filter, dampening the sound of the voice as it travels from the larynx through the airways and lung parenchyma. However, when the lung tissue becomes consolidated, as in the case of pneumonia, the sound waves are transmitted more efficiently, resulting in clearer and louder voice sounds.
Clinical Significance[edit]
The presence of bronchophony is an important clinical finding that can indicate underlying lung pathology. It is often associated with conditions that cause lung consolidation, such as:
In these conditions, the alveoli are filled with fluid, pus, or other material, which enhances the transmission of sound.
Examination Technique[edit]
To assess for bronchophony, the examiner should: 1. Ask the patient to sit upright and breathe normally. 2. Place the diaphragm of the stethoscope on the patient's chest, starting at the upper lung fields. 3. Instruct the patient to repeat a phrase, such as "ninety-nine," while listening to the transmitted voice sounds. 4. Compare the sounds heard over different areas of the lung fields. Increased clarity and loudness of the voice sounds over a particular area may indicate the presence of bronchophony.
Differential Diagnosis[edit]
While bronchophony is a useful sign, it should be interpreted in the context of other clinical findings and diagnostic tests. Other conditions that may cause similar findings include:
