Laryngeal stenosis is a medical condition characterized by the narrowing or constriction of the larynx, which is also known as the voice box. The larynx is located in the throat and plays a crucial role in phonation, respiration, and protecting the airway during swallowing.
The narrowing of the larynx can be caused by various factors, including congenital abnormalities, scar tissue formation, inflammation, trauma, or the presence of abnormal growths. This narrowing restricts the normal flow of air and can lead to significant breathing difficulties, hoarseness, and in severe cases, potential respiratory distress.
Symptoms of laryngeal stenosis may include breathlessness, noisy breathing, a weak or raspy voice, and the sensation of something obstructing the throat. In babies, laryngeal stenosis can also cause feeding difficulties and poor weight gain.
Diagnosis of laryngeal stenosis often involves a thorough examination of the throat and larynx using a laryngoscope, which allows for visualization of the airway. Additional tests such as imaging studies or pulmonary function tests may be required to determine the extent and cause of the stenosis accurately.
Management of laryngeal stenosis depends on the severity and underlying cause. Treatment options may include medication to reduce inflammation or infection, surgical intervention to remove scar tissue or abnormal growths, or reconstructive procedures to widen the narrowed laryngeal area. In some cases, specialized breathing techniques or the use of a tracheostomy tube may be necessary to ensure adequate airflow and prevent respiratory distress.
Overall, laryngeal stenosis is a medical condition characterized by the narrowing of the larynx, leading to potential breathing difficulties and altered vocal function
