CAPSO or electrical cautery, burns the palate causing fibrosis and consequent stiffening of the soft palate. It is also used a means to remove a longitudinal strip of mucosa along the soft palate or uvula. This procedure is performed during a single out-patient visit under local anaesthetic. Because this procedure is less invasive than UPPP or LAUP there are generally fewer complications, however post-operative pain is similar to the other surgical methods. Data now available shows that the short-term efficacy is also similar to that of UPPP and LAUP. As with LAUP, CAPSO can be repeated until the desired effect on the snoring is gained.
