Currently, the most common surgery for sleep apnea is uvulopalatopharyngoplasty, and academician Dr. Han Demin of Peking Tongren Hospital has improved on the traditional “uvulopalatopharyngoplasty”. In the earliest surgery, part of the soft tissue of the soft palate, tonsils and uvula were cut off, but without the obstruction of the “little tongue”, the patient would choke on food after the surgery, especially when drinking water, eating fluid food, and choking out of the nose easily, and speaking with a nasal sound. Palatopharyngoplasty with retention of uvula retains the uvula on the basis of the original surgery, so that the function of the uvula is still there, and by cutting off the surrounding soft tissues, so that the uvula is suspended, a little higher than the original, and if the uvula is still too long, then the bottom is cut off a little more. Laser-assisted uvulopalatopharyngoplasty is rarely done and is only used to cauterize certain areas when they are very vascularized or cannot be easily removed. We use it only when needed, and do not cut it with laser alone, because laser may cause more obvious scars and worse postoperative recovery in some patients. Indications: Patients with loose soft tissue in the soft palate and particularly enlarged tonsils. The surgery will remove the tonsils and remove the excess tissue from the soft palate. In other words, patients whose soft tissues of the pharyngeal cavity cause obstruction are suitable for this surgery. Treatment outcomes: Patients who are assessed as suitable for the surgery prior to surgery have excellent treatment outcomes. Surgical Risks: An important risk common to pharyngeal cavity surgery is bleeding. If the bleeding is not stopped well during the operation, the pharyngeal cavity area may bleed when you first get off the operating table, and when the anesthesia is not yet fully recovered, the blood will not be able to be swallowed by the patient, and suffocation will occur if it chokes in the airway. But the chance of this happening is very, very low. In terms of long-term effects, some patients feel a change in their voice after surgery because the pharyngeal cavity is enlarged. Some patients may choke on food after surgery because they are not used to swallowing after the pharyngeal cavity is widened, which usually improves gradually after half a year. Pain and recovery: The pain is more obvious in the first three days after surgery. The eye of the throat is such a big place, twenty to thirty stitches, it must be painful, and eating, drinking, talking will use this place, or a little painful. After a week the pain is basically reduced, you can eat soft food, do not eat too hard or fried food, after two weeks you can resume a normal diet. There will be edema in the pharyngeal cavity when the surgery is just done, and the snoring may be worse than before the surgery. After 3-5 days, it will gradually improve with the reduction of edema at the wound after the surgery.
