Left RLN: The left nerve has a longer and more complex course than the right. It travels down into the chest and loops under the arch of the aorta before ascending back up to the larynx. A Pancoast tumor in the left lung apex can compress the nerve as it loops under the aorta. Right RLN: The right nerve branches off the vagus nerve and loops under the right subclavian artery. Although its course is shorter, a right-sided Pancoast tumor can also invade or compress it. Symptoms of RLN involvement When a Pancoast tumor affects the recurrent laryngeal nerve, the vocal cord on the same side as the tumor can become paralyzed. This results in the following symptoms: Hoarseness: A persistent, breathy, or weak voice is the most common symptom of RLN injury. Bovine cough: This is a non-explosive, "honking" cough that occurs because the vocal cords cannot close properly to build up pressure. Dysphagia: Some patients may experience difficulty swallowing, particularly with thin liquids. Dyspnea: In rare, severe cases of bilateral vocal cord paralysis, a patient may experience difficulty breathing. Diagnosis and treatment Because symptoms like hoarseness and shoulder pain can be mistaken for other conditions, Pancoast tumors are often diagnosed late. Diagnosis: If RLN involvement is suspected, a thorough physical exam and medical history are performed. Flexible laryngoscopy, which allows for direct visualization of the vocal cords, is often the first step to confirm paralysis. Imaging studies, such as a CT or MRI scan of the chest and neck, are then used to locate the tumor and assess the extent of nerve compression. Treatment: Addressing the RLN injury is part of the overall treatment for the Pancoast tumor. This typically involves a multimodal approach that may include surgery, radiation, and chemotherapy to shrink or remove the tumor. Voice therapy: For less severe cases, speech therapy can help patients learn to use their voice more effectively. Vocal cord medialization: If hoarseness persists, surgical procedures can be performed to reposition the paralyzed vocal cord toward the midline to improve vocal function. Options include injection laryngoplasty or medialization thyroplasty. --------------------------------------------------------------------------------------------------------------------------- Join this channel to get access to the perks: Sign up now on our website at https://members.drnajeeblectures.com/ Follow us on Facebook:- / drnajeeb Follow us on Instagram:- / drnajeeblectures
