PROBOSIS LATERALIS

Proboscis lateralis is an embryological inconsistency which is identified with the middle facial cleft. This outcomes in fragmented arrangement of one side of nose. This underdeveloped nose structure is situated close to the nose but off the midline. It seems like a cylinder and is appended at the undeveloped combination line anytime between the foremost maxillary interaction and the frontonasal cycle. This issue ought to be tended to at an early age and with stage shrewd methodology as this proboscis itself is a valuable design for remaking. We report an instance of proboscis lateralis in a 1-year-old female patient.

A Novel Surgical Method of Reconstruction for Proboscis Lateralis: A Case Report and Review of the Literature

Proboscis lateralis (PL) is a rare congenital craniofacial anomaly and it is represented by rudimentary, tube-like nasal structure measuring 2–3 centimetre (cm) length and generally attaches to medial canthal region. A 22-month-old male patient was referred to our clinic with a PL hanging from the right medial canthus and a coloboma on the medial third of the right lower eyelid. Physical examination revealed that the PL was 4 cm long and 1.5 cm in diameter. There was a blind cavity with dimple at its distal segment. The right side of the nose and the nasal airway was aplastic. Before surgical correction, neuroradiological evaluation should be performed to obtain the characteristics and relationship of the lesion with adjacent structures and associated anomalies Many reconstructive options have been described in the literature, however, these options are insufficient to obtain natural contour and define alar crease, especially. We described the laterally-based skin flap from the medial wall of the left heminose and adapted to the lateral edge of the de-epithelialized skin of PL for defining supra-alar crease.

Ophthalmic manifestations of proboscis lateralis

Proboscis lateralis (PL) is a rare congenital malformation of the craniofacial structure with varied clinical associations. None of the studies documented a discrete review of ophthalmic presentations in PL. The principal aim of the present study is to explore the ophthalmic manifestations of PL. The ancillary goal is to derive a relationship between congenital deformity in PL and various ophthalmic anomalies. Databases were searched in order to obtain articles related to PL. A qualitative systematic analysis of 100 subjects was performed. In PL, eyelid coloboma (32.6%) is the most common ocular feature, followed by hypertelorism (25.3%), iris coloboma (22.4%), lacrimal system abnormality (20.7%), malpositioned eyebrow (14.4%) and retinochoroidal coloboma (12.9%). Sinonasal deformity is the most common systemic abnormality, detected in 87.9% of cases of PL, as compared with central nervous system involvement (56.2%) and other anomalies. The analysis showed a strong significant association between brain abnormalities and hypertelorism (p=0.000) and between brain abnormalities and micro-ophthalmia/anophthalmia (p=0.000). Statistically significant association was noted between cumulative ocular abnormalities and cumulative systemic abnormalities (p=0.001). The present study on PL reviewed the salient features of this rare congenital disorder. The study outcome provides a new aspect to concomitant ocular abnormalities. This study supports the view that other congenital anomalies in cases of PL had significant influence on certain ophthalmic anomalies.

Proboscis Lateralis: A Case Report of Nasal Aplasia with Complete Agenesis of Maxilary and Ethmoidal Sinuses

We report a child with Proboscis Lateralis with nasal aplasia and complete agenesis of maxillary and ethmoidal sinuses. This is a rare congenital malformation. Embryological basis has not been proven, and it is often associated with facial malformation. However, no such abnormality was noted in our patient. This condition is diagnosed clinically and confirmed radiologically of which CT scan plays a pivotal role. Reconstructive surgery is planned at the age of fifteen years.
