Uvulopalatopharyngoplasty for snoring is mainly used for snorers whose upper airway obstruction is caused by oropharyngeal stenosis. However, snorers whose airway obstruction is not in the oropharyngeal plane are not suitable for uvulopalatopharyngoplasty. In addition, people with scars should not undergo uvulopalatopharyngoplasty because the scar contracture of the surgical wound will cause more narrowing of the pharyngeal cavity. In recent years, some scholars have proposed modified uvulopalatopharyngoplasty, which is based on uvulopalatopharyngoplasty, without damaging the physiological function of the soft palate muscles, but only removing the fat pad between the soft palate muscles. It has the ability to reduce the incidence of post-surgical complications such as nasal reflux, open nasal voice, and nasopharyngeal stenosis due to scar contraction. The procedure is less invasive and has a shorter hospital stay. In most provinces and cities, palatopharyngoplasty with preservation of the uvula has been included in the medical insurance, please consult your local medical insurance department for details. 1.Precautions before uvulopalatopharyngoplasty: 1.Patients with snoring should pay attention to the treatment of systemic complications before surgery; 2.Patients with snoring combined with hypertension should be given antihypertensive treatment first, and then operate after the blood pressure is controlled to a certain level, which can reduce the amount of surgical bleeding and prevent cardiovascular and cerebrovascular accidents; 3.Patients with snoring combined with diabetes should have their blood sugar controlled in the normal range first, which can help the postoperative wound healing and prevent the wound infection. 4. For patients with severe obstructive sleep apnea syndrome and severe hypoxemia, non-invasive ventilator should be worn for 5-7 days before surgery to correct the hypoxemia and increase the patient’s stress response ability, which can help the patient’s postoperative recovery and reduce the occurrence of postoperative complications; 5.
