Key Warning Signs Of EEC Syndrome

Distinctive Facial Features

Distinctive facial features may develop in some EEC syndrome patients. Maxillary hypoplasia or upper jaw underdevelopment occurs when the maxillary bones or upper jawbones do not fully form. This lack of development causes the patient's face to have a sunken appearance and makes the lower jaw stick out more than normal. Another common facial feature seen in individuals affected by EEC syndrome is a broad nasal tip. This feature is defined by an excessive increase in width of the nose tip that is abnormally disproportional to the width of the top of the nose. The patient may also exhibit an irregularly long philtrum or groove located between the upper lip and the nose. Choanal atresia often occurs in EEC syndrome patients where the choana or back of the nasal passage is obstructed. This blockage occurs when the nasal channels are not formed correctly during the individual's development in the womb. An uncommon distinctive facial feature seen in those affected by EEC syndrome is abnormally small ears. The auricles or outer parts of the ear may also be malformed.
