In teratology, a proboscis is a blind-ended, tube-like structure, commonly located in the middle of the face. It is commonly seen in severe forms of holoprosencephaly that include cyclopia and is usually the result of abnormal development of the nose.

Aug 30, 2024 · Proboscis is a rare congenital anomaly where an anterior appendage-like structure is seen projecting from the midline fetal face/forehead. Depending on the exact location, this has further been classified into various subtypes (e.g. interorbital proboscis).

Proboscis lateralis (PL) is a rare craniofacial anomaly with a reported incidence of less than 1 in 100,000. This condition is caused by the developmental failure or absence of medial and lateral nasal processes, resulting in fusion of the maxillary …

Apr 27, 2011 · Proboscis Lateralis is a very rare congenital anomaly characterized by a rudimentary tubular, nose-like structure most of the cases arising from the medial portion of the orbital roof . Lateral proboscis is a rare anomaly, with …

Cyclopia with a proboscis, a rare congenital anomaly, and a severe form of holoprosencephaly occur as a result of incomplete separation of prosencephalon into two halves of hemispheres during organogenesis. A prenatal anomaly scan can help in the ...

Proboscis Lateralis is a very rare congenital anomaly characterized by a rudimentary tubular, nose-like structure most of the cases arising from the medial portion of the orbital roof [1]. Lateral proboscis is a rare anomaly, with a reported incidence to be less than 0.1:10,000 [2].

Proboscis lateralis is a rare deformity of the nose with an incidence of 1 in 100,000 babies, alive at birth, and is not sex-related. The causative factor of this anomaly is thought to be an injury of the nasal placode. The treatment is by reconstructive surgery in the pre-school years, using the proboscis lateralis, itself, when there is a

Proboscis, abnormal nose formation, is almost always related to hypotelorism and holoprosencephaly. The sonographic findings reveal an appendage with one or two openings which replaces the nose. It is located midline at the level of orbit, upper or lower, and is usually diagnosed in the second trimester but possibly in the first trimester.

A lateral proboscis can be an isolated anomaly but the risk on eye anomalies or clefts in the upper lip, palate or the cheek is high. Brain anomalies are sometimes present but rare.

Proboscis lateralis (nasal aplasia with probos cis) is a rare congenital craniofacial anomaly occurring in less than 1/100,000 births. Proboscis is derived from the Greek word "proboskis" for trunk. This soft tubular process typically mea sures 2-3 em in length and 1 em in diameter and arises from the inner canthus of the eye ( 1 ).
