A single dose of 8-10 mg of intravenous dexamethasone can be administered prior to surgery. Antibiotics are not necessary.

The surgeon should wear a headlight for illumination during the procedure. A mouth prop (McIvor or Crowe-Davis) is used to gently open the oral cavity and is suspended from a Mayo stand. An appropriately sized tongue blade should retract the tongue without touching the posterior oropharyngeal wall.

The tongue and endotracheal tube should be positioned in the center of the tongue blade. If the tongue is particularly large, the blade may need to be positioned for removal of the first tonsil, followed by repositioning prior to removal of the other tonsil. The hard palate is then palpated for the presence of a submucosal cleft. If a submucosal cleft is present, surgery should be avoided because of the possibility of postoperative velopharyngeal insufficiency.
