Abordaje Transoral para la Extracción de un Diente Supernumerario Intranasal. Presentación de un Caso y Revisión de la Literatura

The supernumerary tooth of nasal location is a pathology of low prevalence in the population with different forms and clinical symptoms. It is important to establish a diagnosis regarding its clinical and radiological characteristics in order to carry out adequate surgical treatment planning, with few or no post-intervention complications. Case presentation: This study reports the case of a 10-year-old boy, with no morbid history, who presented a supernumerary tooth, found radiographically in the midline. CBCT showed a mesiodens in the nasal septum, tilted and inverted palatal, partially erupted covered by nasal mucosa, with its crown facing the nasal cavity in relation to the nostrils. The tooth was extracted under general anesthesia using a transoral approach through a vestibulotomy. The nasal supernumerary tooth is a rare pathology. It is important to know its clinical and radiographic characteristics since they will determine the type of approach to be used. The degree of eruption, the distance to the anterior nasal spine and its associated symptoms are essential to determine whether the surgical approach is intraoral or extraoral.
