RESUMEN
@#<p style="text-align: justify;"><strong>OBJECTIVE:</strong> This report aims to describe unique manifestations of proboscis lateralis and highlight the importance of a multidisciplinary approach to address the problems that arise from this rare congenital anomaly.<br /><strong>METHODS:</strong><br /><strong>Design:</strong> Case Report<br /><strong>Setting:</strong> Tertiary Government Hospital<br /><strong>Patient:</strong> One<br /><strong>RESULTS:</strong> A 13-year-old girl diagnosed with proboscis lateralis presented with a trunk-like appendage projecting from the surface of the right supramedial canthal area. She also had clear nasal discharge, nasal congestion, mouth-breathing and snoring since birth. Paranasal Sinus (PNS) CT scan with 3D reconstruction showed agenesis of the right paranasal sinuses and expansile aeration of the left paranasal sinuses. Due to her condition, the drainage system of the paranasal sinuses was obstructed causing chronic rhinosinusitis (CRS). This hindered plans for reconstructive surgery despite medical management, hence, the patient underwent Endoscopic Sinus Surgery (ESS).<br /><strong>CONCLUSIONS:</strong> Proboscis lateralis is a rare congenital anomaly that results in aesthetic problems as well as airway concerns such as rhinosinusitis and obstructive sleep apnea syndrome (OSAS). Management entails a multidisciplinary approach to address functional and aesthetic problems of the patient.</p>
