title: Endoscopic removal of supernumerary tooth from the nasal cavity of a child: a case report.
abstract: BACKGROUND
  A case report showing the removal of a supernumerary tooth from the nasal cavity by means of an endoscopic approach is presented.
  
  
  METHODS
  A 9-year-old healthy child presented to our department because of the right central incisor which appeared clinically rotated. The observation of orthopantomography revealed the presence of a supernumerary tooth in the anterior maxilla with the crown positioned towards the nasal floor. The maxillary CT demonstrated a quite close relationship of the tooth with the nasal cavity, so a nasal approach was planned.
  
  
  RESULTS
  Under general anesthesia the supernumerary tooth was removed by means of an endoscopic approach from a nostril. During the extraction the adjacent structures were unharmed. The postoperative course was uneventful.
  
  
  CONCLUSIONS
  This case report suggests that in case of supernumerary teeth positioned close to the nasal cavity, trans-nasal endoscopy may represent a valid alternative to more demolishing traditional surgery.
