A Case Report on Lateral Proboscis: A Rare Congenital Anomaly.

Lateral proboscis is a rare congenital condition characterized by a cylindrical protuberance on the nasofrontal region accompanied by abnormal nasal development on the affected side. We aimed to describe the management of the lateral proboscis in staged repair. A 7-year-old girl came with a tube-like projection on the left medial canthal region and nasal agenesis on the ipsilateral side. She was diagnosed with lateral proboscis, left microphthalmia, lower eye lid coloboma, and asymmetry in the orbital region. The patient has undergone 3 major surgeries at our institution. The first surgery involved the deconstruction of the tube to form the left nasal body and nostril. The second operation involved trimming of the new nose form and the excision of the bony protrusion directly beneath the base of the pedicle through bifrontal craniotomy. The remaining bone defect was closed using a pericranial flap. The orbital floor was reconstructed using titanium mesh. The third operation involved nasal reconstruction using a costal cartilage graft to create a dorsal nasal and alar framework. The patient healed with no complications, had become less reserved and her grades improved significantly after the operation. Further appointments are being scheduled to evaluate growth distortion and the resulting facial asymmetry. Surgical correction will be planned thereafter to further reconstruct the facial features. Evaluation of patient is necessary to explore possible clinical outcomes and corresponding treatment options. Multidisciplinary management is highly recommended, involving plastic surgeons, neurosurgeons, ophthalmologists, pediatricians, and pediatric psychiatrists in order to improve patient's quality of life.
