The first choice of treatment for all patients was surgery. After function neck dissection and tracheotomy, partial laryngectomy and hypopharyngectomy were carried out. The folded island flaps were prepared and used for the repairs of laryngeal and hypopharyngeal defects and the reconstructions laryngeal and hypopharyngeal functions. The patients were followed up. <b>Results:</b> The laryngeal and pharyngeal cavities were reconstructed well in 10 patients, and all the flaps survived, with no case of pharyngeal fistula. All patients were able to eat normally through the mouth at 2 weeks after surgery without obvious choking, and 4 patients completed the swallowing function evaluation without aspiration or only a small amount of aspiration. All the 10 patients underwent postoperative radiotherapy. The postoperative follow-up time was 5.4-41.4 months, and there was no case with tumor recurrence or death. Laryngoscopy showed that 8 patients had a spacious new laryngeal orifice, which met the conditions for extubation, of whom 7 patients had their tracheal tubes removed and 1 patient was still under observation, and that 2 patients had a slightly narrowed new laryngeal orifice due to a thick skin flap, with further follow-up observation.

One hundred and forty-five subjects consisting of 75 males and 70 females included in the final analysis, with an average age of (35.30±12.41) years, an average height of (168.23±8.08) cm, and an average weight of (68.28±13.74) kg. The subjects were divided into four groups based on the apnea-hypopnea index (AHI): <5.0 events/h (non-OSA group, 39 cases), ≥5.0-<15.0 events/h (mild OSA group, 47 cases), ≥15.0-<30.0 events/h (moderate OSA group, 25 cases), and≥30.0 events/h (severe OSA group, 34 cases). Intraclass correlation coefficients (ICC), Pearson correlation coefficients (<i>r</i>), and Bland-Altman analysis were employed to assess the agreement between the two monitoring techniques regarding AHI and other parameters. Sensitivity and specificity of the QSA600 in diagnosing OSA were evaluated at different AHI thresholds.

Additionally, influencing factors of curative effect and prognosis were statistically analyzed. <b>Results:</b> Among the 169 patients, 50.9% (86/169) of patients had at least one incentive, with cold and fatigue being the most common incentives(both 23/169).
