Clinical Information for Other congenital malformations of tongue, mouth and pharynx (Q38)

Macroglossia - The presence of an excessively large tongue, which may be congenital or may develop as a result of a tumor or edema due to obstruction of lymphatic vessels, or it may occur in association with hyperpituitarism or acromegaly. It also may be associated with malocclusion because of pressure of the tongue on the teeth. (From Jablonski, Dictionary of Dentistry, 1992)

Ankyloglossia - A severe congenital restriction of TONGUE movement, resulting from fusion or adherence of the tongue to the floor of the mouth. In partial ankyloglossia (tongue-tie) the LINGUAL FRENUM is abnormally short, or is attached too close to the tip of the tongue. OMIM: 106280

Ranula - A form of retention cyst of the floor of the mouth, usually due to obstruction of the ducts of the submaxillary or sublingual glands, presenting a slowly enlarging painless deep burrowing mucocele of one side of the mouth. It is also called sublingual cyst and sublingual ptyalocele.

Oral Fistula - An abnormal passage within the mouth communicating between two or more anatomical structures.

Persistent Hyperplastic Primary Vitreous - A developmental ocular anomaly in which the primary VITREOUS BODY and its surrounding hyaloid vasculature failed to regress. It is usually unilateral and characterized by CATARACT; MICROPHTHALMOS (small eyeballs), and retrolenticular fibrovascular tissue. (from Yanoff: Ophthalmology, 2nd ed.)

An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
