Paranasal sinus (PNS) osteomas are benign growths that are usually asymptomatic and often discovered incidentally upon imaging. Nasal polyps, on the other hand, are relatively commoner than osteomas. With the adoption of endoscopic technology in the otorhinolaryngology (ORL) field, surgeons are shifting toward less invasive surgical methods in managing such cases. We present a case of a 23-year-old male who had chronic rhinosinusitis with nasal polyps. A computed tomography (CT) done as part of his preoperative planning revealed findings suggestive of nasal polyps with left frontal recess osteoma. Both pathologies were removed successfully via an endoscopic endonasal approach.
