What is a primary symptom of subcutaneous emphysema?

A primary symptom of subcutaneous emphysema is a change in voice. This condition occurs when air enters the subcutaneous tissue, often due to a punctured lung or other injuries that allow air to escape from the respiratory tract. When this happens, the accumulated air can create pressure under the skin, especially around the neck and chest, which may lead to swelling in these areas.

As the swelling progresses, it can put pressure on the vocal cords or other structures of the throat, resulting in a change in voice quality. Individuals may notice a hoarse voice or a strained sound as the air-induced pressure affects normal vocal cord function. Understanding this symptom is crucial for recognizing potential complications from diving-related injuries or other traumas.
