Research Article: Aspiration prevention surgeries: a review

Date Published: 2023-05-03

Abstract:
Severe dysphagia can cause intractable pneumonia and lead to life-threatening conditions. Intractable aspiration can occur despite medical management for aspiration prevention. Surgical intervention is indicated for intractable aspiration to prevent potentially life-threatening complications. Since the 1970s, several surgical treatments to prevent aspiration have been reported, and various aspiration prevention surgeries have been introduced, but little is known about them or their benefits. This is a review of the types of aspiration prevention surgery, with the aim of increasing aspiration prevention surgery awareness and their clinical outcomes among medical professionals, which will guide the choices of aspiration prevention surgeries for patients with intractable aspiration.

The larynx plays important roles in various body functions, which include respiration, speech, and protection of the lower airway. Impaired laryngeal function is associated with dysphagia and intratracheal aspiration (aspiration). Dysphagia is associated with aging and neuromuscular, cerebrovascular, esophageal, and laryngopharyngeal disorders. Aspiration can occur when there is laryngeal penetration of secretions such as saliva, ingested liquids or solids, or refluxed gastric contents below the level of the true…
