**6. Physical examination**

UARS patients differ anthropometrically from patients with SAHS. They are generally thin, young, and predominantly female. The recommended physical examination is similar to that for OSAS patients. As in OSAS, craniofacial abnormalities such as elongated face and reduced mouth opening are frequent. Guilleminault described an increase in nasal resistance, excessive pharyngeal tissue, mild retrognathia, narrowing of the oropharynx and ogival hard palate (Guillemianult 1995), with high scores on the Mallampati scale.
