The loss of voice and of normal and efficient verbal communication is a negative consequence associated with this type of surgery and can have significant impacts on the quality of life of these individuals. [20] [21] Voice rehabilitation is an important component of the recovery process following the surgery. Technological and scientific ...
The two main methods of treating vocal fold nodules are voice therapy (a behavioural treatment) and laryngeal microsurgery (a surgical treatment). [17] Because of general risks of surgery (e.g. scar formation, or those posed by general anesthesia [17]), behavioural treatment is usually recommended first. [17]
Further treatment or revision surgery might be needed for some patients with serious unresolved sound hoarseness after extended periods of recovery. [16] If the vocal cords heal with asymmetrical tension, laser treatment is generally required to correct the defect.
The recurrent laryngeal nerves may be injured as a result of trauma, during surgery, as a result of tumour spread, or due to other means. [ 16 ] : 12 Injury to the recurrent laryngeal nerves can result in a weakened voice ( hoarseness ) or loss of voice ( aphonia ) and cause problems in the respiratory tract .
These conditions result from continuous damage to the laryngeal nerves [4] [3] and often lead to vocal disability. [6] Recurrent laryngeal nerve damage is the most common cause of vocal fold paresis. [4] The RLN is responsible for motor input to the vocal folds. [4] Physicians may also use the term recurrent laryngeal nerve paralysis. [19]
Laryngotracheal stenosis is an umbrella term for a wide and heterogeneous group of very rare conditions. The population incidence of adult post-intubation laryngotracheal stenosis which is the commonest benign sub-type of this condition is approximately 1 in 200,000 adults per year. [10]
During surgery, attempts are made to preserve as much vocal fold tissue as possible, [3] given that glottal insufficiency (a gap in the vocal folds) is a possible consequence of surgery. [15] Vocal fold tissue can be preserved during surgery by raising a micro-flap, removing the cyst, then laying the flap back down. [ 15 ]
With sensory testing, one can demonstrate that the throat tissues are numb, signifying some damage to the sensory fibers of the vagus and thereby identify vagus nerve injury as the cause of the patient's pain. This is called vagus nerve neuralgia and treatment for neuralgia can then commence.
