Clinical observation notes migration of bone in nasofrontal duct post-neurosurgical operation, suggesting complications like sinusitis.
The article describes a clinical observation of a patient with bone replacement material migrated from the frontal sinus to the nasofrontal duct after supraorbital Keyhole craniotomy. Long-lasting presence of the bone replacement material in the nasofrontal duct and partially in the cavity of the left frontal sinus has led to the development of secondary polypous ethmoiditis, exudative left-sided frontal sinusitis and maxillary sinusitis.
