A comparison of the Fujita classification of awake and drug-induced sleep endoscopy patients

Only a few studies have compared the outcomes of patients kept awake during endoscopic examination and subjects submitted to drug-induced sleep endoscopy.ObjectiveThis study aimed to compare the endoscopic findings of patients submitted to outpatient endoscopy and endoscopic examination with sedation by propofol based on the Fujita Classification.MethodThis cross-sectional cohort study enrolled 34 patients. The subjects underwent ENT examination, nasal endoscopy with Müller's maneuver, and drug-induced sleep endoscopy with propofol. The Fujita Classification was used to compare the two modes of endoscopic examination. The examinations were correlated to patient clinical data such as BMI, age, and OSAS severity.ResultsThere was no agreement between the two modes of endoscopic examination, whether for the group in general or for the analyzed subgroups.ConclusionThere was no agreement between the endoscopic findings of endoscopic examinations done with the patient awake or in drug-induced sleep.     

Sleep Apnea and Down's Syndrome

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.     

Preliminary Findings from Our Experience in Anterior Palatoplasty for the Treatment of Obstructive Sleep Apnea

Objectives

Obstructive sleep apnea (OSA) is a common disorder affecting at least 2% to 4% of adult population characterized by the collapse of the pharyngeal airway. It is well established that retropalatal region is the most common site of obstruction. Consequently, many surgical techniques have been introduced. The purpose of this study is to present our preliminary results in the anterior palatoplasty (AP) compared with results of uvulopalatal flap (UPF).

Methods

Thirty-eight consecutive patients with mild-moderate OSA were prospectively enrolled into a randomised surgical protocol. Surgical success was measured primarily by satisfactory reduction in snoring, as reported by snoring assessment questionnaire (SQ) of sleep partners. Secondary outcomes measures included improvement in the Epworth Sleepiness Scale (ESS) scores, changes in the magnitude of pharyngeal collapse, and postoperative pain intensity.

Results

The ESS after AP improved from a preoperative value 8.5±3.7 to a postoperative mean of 4.9±3.2 (P<0.001) after UPF improved from a preoperative value of 8.1±3.5 to 5.2±3.2 postoperatively (P<0.001). The results of satisfactory reduction in the volume of snoring and response at polysomnographic data were also similar in both procedures. We reported a statistically significant difference of the collapse noted at Müller manoeuvre that improved from 2.7±1.0 on average, to 1.1±0.9 (P<0.001) after AP and with a lesser extent, (from 2.8±1.1 on average to 1.8±1.1; P<0.05), after UPF. The mean duration of pain was 10.8 days for UPF patients and 7.1 days for AP patients. The mean pain score in the first 3 days, was 6.8 in UPF patients and 5.1 in AP patients.

Conclusion

The subjective and objective improvements evidenced may suggest how AP is far superior to other techniques aimed at creating a palatal fibrotic scar. In the light of these results we can suggest AP procedure as more practical and comfortable when compared to UPF.
