(Thiel, Clement, & Kubba, 2011). Richter documented the first laryngeal cleft in 1792 when he performed an examination of aspirating newborn. However, the first successful surgical repair procedure was performed over 150 years later in 1955 by Petterson (Chien et al., 2006). It is more common in males than females.

However, both FEES and MBS do not account for all levels of swallowing and may produce normal results when there may be a problem. Therefore, specialists have deemed the gold standard for the diagnosis as microlaryngoscopy under general anesthesia. This procedure allows for professionals to get a closer and in depth look look at the larynx
