Surgery for snoring mainly refers to uvulopalatopharyngoplasty, which is performed by firstly bilateral tonsillectomy, then removing part of the palatine arches on both sides of the uvula, and pulling out some of the fat in the palatine sail space on both sides of the uvula to make the soft palate thinner. By suturing the pharyngeal and palatal arches, the lingual and palatal arches and the soft palate, the pharyngeal cavity is widened and raised significantly, and the uvula will become very long after the operation, which is also partially excised to make it shorter. The key points of uvula palatopharyngoplasty are the hollowing out of the fat in the palatofacial space and the tight suturing of the lingual and pharyngeal palatine arches, which are open in many patients after the operation, affecting the results. The suture of the surgical incision is critical, and the postoperative suture of the uvula and soft palate is the most critical, which directly affects the postoperative effect and aesthetics.
