A 62-year-old female presented with complaints of persistent phantosmia (foul smell) for the last 4 months. She has a past history of right-sided dacryocystorhinostomy (DCR) 18 months back and left-sided DCR 12 months back. In the initial follow-up period, the patient had frequent visits to her otolaryngologist and ophthalmologist. She experienced phantosmia often but was reassured. The patient presented to us and was examined in an operation theater. It was discovered that the foul-smelling foreign body was present in her right nasal cavity above the middle turbinate. It was removed. A retained gauze piece was revealed to be a cause of phantosmia. The purpose of reporting is to create awareness among ophthalmologists and otolaryngologists. Retained gauze piece following DCR surgery presenting as phantosmia is a new symptom after DCR surgery previously not reported in the literature. Repeated complaints of a postoperative patient, should be dealt with vigilantly and timely.
