NASOPHARYNGEAL stenosis is a relatively rare condition. It consists in scarring and contracture of the mucous membrane and submucosal tissues of the nasopharynx following destructive damage to them. This process may involve the posterior pharyngeal wall anywhere from the adenoids down. It then may include the lateral walls and extend forward to the pillars of the fauces. Some cases include the free margins of the palate as well. There are all degrees of involvement, from moderate distortion of the normal anatomy, not giving rise to symptoms, to inclusion of all the structures, resulting in a contracture ring that distorts the entire nasopharynx and occludes it with a thick diaphragm of scar tissue, which gives rise to nasal obstruction and a change in voice.
The etiologic factors behind this picture of destruction and scarring of the tissues are trauma and infections. Traumatic injury may follow burns, but burns due to lye
