title: [Soft palate transnasal retractor].
abstract: BACKGROUND
  An anterior transoral approach allows the surgeon to access the lower portion of the clivus; to the first, second or third thoracic vertebra. It is indispensible that the teeth, lips, cheeks and tongue be retracted to avoid interposition on the surgical field. This retraction is carried out by means of a Dingman separator. Nevertheless, generally the soft palate is elevated with sutures through the nasal fossa. Because this invasive method could damage soft tissues, we have designed a basket to separate the soft palate from the surgical field, thus allowing the surgeon to maneuver with comfort and without damaging structures.
  
  
  METHODS
  A 30-cm segment of 22 gauge wire is passed through each end of a thin sheet of silicon (4 x 3 x 1.5 cm) forming a basket. With the patient under general anesthesia, both free ends of the wire are introduced into the buccal cavity in the same manner nasal packing is used to control epistaxis. Each end of the wire is slid from the mouth through the nasal fossa to bring them outside the face. Traction is placed on both ends of the wire allowing the intraoral band of silicon to elevate and hold the soft palate.
  
  
  METHODS
  We present the case of a 64-year-old woman with spastic quadriparesis and hyperreflexia predominantly of the upper extremities, in addition to trophic changes due to arthritis of long duration. Imaging studies demonstrated nonreducible subluxation of the atlantoaxial joint with ventral compression of the bulbomedullar union by the odontoid apophysis. Resection of the anterior arch of the atlas and apophyses was made via the transoral route, where retraction of the soft palate by means of the described basket was employed. The patient did not experience significant sequelae as a result of the technique utilized.
