A 17-year-old patient with no specific pathological history who consulted for epistaxis with low abundance repetitions by the left nasal fossa associated with a homolateral stuffy nose sensation and episodes of fetid rinorrhea, since 7 months. The clinical examination reveal a patient in good shape . Examination of the nasal cavities found some blood clots in the left nasal cavity , the suction cannula was blocked by a whitish formation of bone consistency implanted in the floor of the left nasal cavity and causing a bleeding contact of the nasal mucosa . The oral examination, in particular that of the upper dental arch, did not show any morphological abnormality or in number. The sinus CT scan made in spiral acquisition in coronal (A) and axial (B) sections in bone window has showed the presence of a spontaneously hyperdense lesional process in the left nasal cavity in front of the inferior nasal concha, in relation to a tooth Included (arrow). The patient benefited from an endoscopic extraction of this tooth after a local anesthesia obtained by a good naphazoline xylocaine squeezing. The operative sequences were simple. The evolution was marked by the disappearance of the epistaxis and the nasal obstruction. Dental eruption in the nasal cavity is one of the topographic forms of dental ectopy. This unusual situation must be evoked before epistaxis and unilateral purulent fetid rhinorrhea.
