A facial nerve injury refers to damage to the seventh cranial nerve, commonly known as the facial nerve. This nerve controls most of the muscles in the face and is responsible for expressions like smiling, blinking, and frowning. It also plays a role in speech, chewing, and tear and saliva production. When the facial nerve is injured, it can lead to partial or full paralysis, facial droop, involuntary muscle movements, or loss of taste on part of the tongue. The severity of the injury depends on how and where the nerve is damaged.

The phrenic nerve is a critical nerve in the body that controls the diaphragm, the primary muscle used for breathing. Injury to the phrenic nerve can occur during high-risk surgeries, or if medical professionals fail to take proper precautions. Without proper function of the phrenic nerve, the diaphragm may not work correctly, leading to breathing problems or even respiratory failure in severe cases.

Vocal cord paralysis is a serious condition that can profoundly impact a person’s ability to speak and breathe. While it is often the result of surgical errors, it can also be caused by other forms of medical malpractice, including improper intubation, delayed diagnosis of nerve damage, or adverse effects from certain medications. In some cases, medical providers fail to recognize or address complications that lead to permanent vocal cord impairment.
