What happens when the recurrent laryngeal nerve is damaged?
Damage to the laryngeal nerve can result in loss of voice or obstruction to breathing. Laryngeal nerve damage can be caused by injury, tumors, surgery, or infection. Damage to the nerves of the larynx can cause hoarseness, difficulty in swallowing or breathing, or the loss of voice.
Why is the left recurrent laryngeal nerve more vulnerable to damage?
Relationship of the recurrent nerve to the inferior thyroid artery. The nerve often passes anterior, posterior, or through the branches of the inferior thyroid artery. Medial traction of the thyroid lobe often lifts the nerve anteriorly, thereby making it more vulnerable.
What is the function of the inferior laryngeal nerve?
Inferior laryngeal branch of the recurrent laryngeal nerve: excluding the cricothyroid muscle [innervated by the superior laryngeal nerve], the inferior laryngeal branch of the recurrent laryngeal nerve innervates all intrinsic muscles of the larynx.
What does the recurrent laryngeal nerve do?
The recurrent laryngeal nerve (RLN) branches off the vagus nerve (cranial nerve X) and has an indirect course through the neck. It supplies innervation to all of the intrinsic muscles of the larynx, except for the cricothyroid muscles, as well as sensation to the larynx below the level of the vocal cords.
How do you treat recurrent laryngeal nerve damage?
The late treatment methods of RLN injury include thyroplasty, injection into and near vocal cords and arytenoid adduction, in order to move the vocal cords inward and to improve the voice; and laser arytenoidectomy, cordectomy, vocal cord abduction and fixation in order to expand glottis and improve the dyspnea.
How long does it take for recurrent laryngeal nerve to heal?
On comparing with the existing literature, the majority of the nerves recover function within the first 6 months after surgery.15, 16 However in our cohort, patients undergoing redo surgery had a longer recovery interval with some recovering function as late as 26 months.
How do you fix a recurrent laryngeal nerve?
Methods of immediate intraoperative repair of the RLN include direct end-to-end anastomosis, free nerve graft anastomosis, ansa cervicalis to RLN anastomosis, vagus to RLN anastomosis, and primary interposition graft. Techniques of nerve repair include micro-suturing, use of fibrin glue, and nerve grafting.
What causes laryngeal sensory neuropathy?
An uncommon cause of chronic cough is laryngeal sensory neuropathy. This occurs when the larynx suffers an injury and becomes hypersensitive to the slightest irritant resulting in a chronic dry cough.
What are the 3 important laryngeal muscles?
The muscles in this group include the stylohyoid muscle, the digastric muscle and the mylohyoid muscle. The stylopharyngeus muscle is not attached directly to the hyoid bone, however it acts indirectly to elevate both the hyoid bone and the larynx.
Can the recurrent laryngeal nerve heal?
Conclusions: RLN paralysis does not always have to be considered permanent. Some surgical techniques, like nerve liberations, along with phonorehabilitation, can be successfully used for recovery of RLN function after paralysis. It is even possible to achieve complete vocal cord mobility many years after RLN paralysis.
Can neck nerve damage be repaired?
Can it be cured? Although there are several very good nonsurgical and surgical treatment options available to relieve the symptoms of cervical myelopathy and radiculopathy, there is no cure, per se, for the degenerative changes in the cervical spine that caused the symptoms.
How do you treat a recurrent laryngeal nerve injury?
What is the inferior nasal turbinate?
The inferior nasal turbinate is an important structure located in the nasal cavity. Often described as a “finger-like projection”, the inferior nasal turbinate extends from deep inside the nose towards the anterior (front) nasal cavity. It is one of three pairs of nasal turbinates that are orientated in “shelf-like” fashion within the nose.
What is inferior turbinate reduction?
Inferior Turbinate Reduction. The aim of inferior turbinate reduction procedure (an allergy and sinus treatment) is to shrink swollen nasal turbinates that obstruct your nasal passages (which can cause frequent sneezing, congestion, headaches, sinus infections, and sleep apnea). Sinus Solutions of South Florida can perform several types…
What does it mean when your turbinates are too big?
Sometimes the turbinates are large enough to cause difficulty with nasal breathing. This condition is called, “inferior turbinate hypertrophy”. Enlarged nasal turbinates can be caused by a variety of issues, including seasonal allergies, chronic sinusitis, or anatomical factors such as a deviated nasal septum.
What is the anatomy of the turbinates?
What is the anatomy of this part of the nose, what is its function, and what disorders may occur? Turbinates, which are also called nasal concha or conchae (plural), are shell-shaped networks of bones, vessels, and tissue within the nasal passageways.
