We have not encountered either primary or secondary hemorrhage following harmonic tonsillectomy, or ultrasonic tonsillectomy. Average time is 15 to 20 minutes, as opposed to five or 10 minutes with electrosurgery. It's just the surgical procedure part, excluding the induction of anesthesia, or bringing the patient back from anesthesia. These are the recommendations. Basically, there is no contraindication for tonsillectomies, but there are for adenoidectomy.
Adenoids are like tonsils, sitting behind the nose above the soft palate.
The patients who have some submucosal cleft of the soft pallet, are bifid uvula, because that can cause velopharyngeal insufficiencies, where food or drink can regurgitate from the mouth into the nasal cavity. The harmonic scalpel is the only device that uses ultrasonic energy, as opposed to any other device available in the market. All of them use heat energy. Since I'm not a pediatric surgeon, I haven't done huge numbers of tonsillectomies, but in the institution, we have done a large number of tonsillectomies using the harmonic scalpel. If the surgeon is familiar with the device, they can use this.
