Day case endoscopic excision of an antrochoanal polyp in a paediatric patient.

Antrochoanal polyps (ACP; also known as Killian's polyp) are considered to be the most common type of choanal polyps, making up ~4-6% of all nasal polyps in the general population and ~33% of nasal polyps in the paediatric age group. Patient's suffering from ACP range between the ages of 5 and 80 years. Only 4% of the patients are children aged < than 10 years old. Overall there is a male predominance making up ~64% of the total number of patients. We report a case of an antrochoanal polyp in a 9-year-old girl who presented with complaints of unilateral nasal obstruction, snoring and obstructive sleep apnea. The patient underwent a computed tomography scan and was managed endoscopically for excision of the polyp, as a day case procedure.
