- UNLABELLED: CONCLUSIONS, There are gender differences when it comes to the risk factors for sleep apnea. Large tonsils, a high tongue and a wide uvula are risk factors for sleep apnea in men, while large tonsils and a retrognathic mandible are risk factors in women. Upper airway abnormalities including mandibular retrognathia are, however, unable to predict sleep apnea among snorers being investigated for suspected sleep apnea.OBJECTIVES: To identify gender-specific risk factors for obstructive sleep apnea and the diagnostic performance from physical upper airway examinations among snoring men and women investigated because of suspected sleep apnea.PATIENTS AND METHODS: The dimensions of the uvula, tonsils, velopharynx and tongue, and nasal septal deviation, mandibular position, neck circumference, weight, and height were systematically scored in 801 consecutive snoring patients (596 men and 205 women), who had been referred for a primary sleep apnea recording.RESULTS: In men, large tonsils, a high tongue, and a wide uvula were independent factors associated with an apnea-hypopnea index of >15. In women, large tonsils and mandibular retrognathia were independent factors associated with an apnea-hypopnea index of >15. The positive predictive values for upper airway abnormalities ranged between 0.20 and 0.25 in men and between 0.09 and 0.15 in women.

- OBJECTIVE: Obstructive sleep apnea has been reported to occur in 20-50% of children with Down's syndrome in case series of patients referred for evaluation of suspected sleep apnea. In this population-based controlled study, we aimed to investigate whether sleep apnea is related to Down's syndrome.MATERIAL AND METHODS: Every child aged 2-10 years with Down's syndrome residing in the Umeå healthcare district (n = 28) was invited to participate in the study, with their siblings acting as controls. Successful overnight sleep apnea recordings and echocardiography were performed in 17/21 children with Down's syndrome and in 21 controls.RESULTS: Obstructive sleep apnea could not be diagnosed, either in children with Down's syndrome or in the control children. The apnea-hypopnea index in the children with Down's syndrome was 1.2 +/- 1.5 and did not differ from that in controls. Snoring and hypertrophy of the tonsils were more common in children with Down's syndrome than in controls. Children with Down's syndrome slept for a shorter time (p < 0.001) and changed body position more often (p < 0.05) than the control children.CONCLUSIONS: Snoring, restless sleep and hypertrophy of the tonsils were common among children with Down's syndrome. Obstructive sleep apnea was, however, not related to Down's syndrome in the present population-based controlled study.

- OBJECTIVE: To test the hypothesis that preoperative asymptomatic pharyngeal swallowing dysfunction predisposes for the development of symptoms of dysphagia after uvulopalatopharyngoplasty (UPPP) and uvulopalatoplasty (UPP). MATERIAL AND METHODS: A total of 42 patients who snored were scheduled to undergo UPPP (n = 20) or UPP (n = 22). UPP was performed using either a CO2 laser or a conventional steel scalpel. Preoperatively and 1 year postoperatively all patients were examined videoradiographically to assess pharyngeal swallowing function. They also completed a questionnaire pre- and postoperatively concerning their snoring problems and swallowing function as well as the outcome of surgery. RESULTS: Preoperatively, 7 (17%) patients reported dysphagia. Pharyngeal swallowing dysfunction was demonstrated in 6/7 patients with preoperative dysphagia while pharyngeal swallowing dysfunction was evident preoperatively in 18/35 non-dysphagic patients. Of the 35 patients without preoperative dysphagia, 10 (29%/) developed dysphagia after surgery. There was no significant risk of development of postoperative dysphagia for patients with compared to patients without preoperative pharyngeal swallowing dysfunction. Only one of the seven patients with preoperative dysphagia experienced worsening of the problem. A total of 93% of the patients reported a decrease in snoring and 95% reported a decrease in daytime sleepiness. CONCLUSIONS: Preoperative pharyngeal swallowing dysfunction was not proven to predict the development of dysphagia after UPPP or UPP. The surgical method did not influence the frequency of postoperatively acquired dysphagia. The results do not indicate that patients with preoperative dysphagia should be excluded from treatment with UPPP or UPP.
