Mesiodens is the most common type of supernumerary tooth, located between the maxillary central incisors in close relation to the nasopalatine canal. A 20-year-old man presented with right-sided nasal blockage, nasal discharge and collapsed nose without history of trauma. Imaging revealed a calcified mass in the inferior meatus extending into dilated nasopalatine canal. Endoscopic removal of the mass revealed tuberculate appearance of an incompletely developed tooth, consistent with mesiodens. Based on the history of septal cartilage collapse with right-sided mucopurulent discharge, endoscopic findings of the right inferior turbinate being adherent to the septal cartilage and the underlying mesiodens, we believe that the patient developed a septal abscess secondary to infection in nasal mucosa surrounding the mesiodens causing collapse of septal cartilage. While a tooth or tooth-like mass causing nasal passage air-flow obstruction is uncommon, we believe that this is the first reported case of mesiodens presenting with septal cartilage collapse.
