“…First described in 1991, the technique requires the pharmacologic induction of sleep and the placement of a flexible fiberoptic telescope (passed through the nose) to visualize the upper airway 8, 9. This provides an opportunity to observe directly and characterize the upper airway collapse that occurs during drug-induced sleep.…”

Objective To determine the test-retest reliability of drug-induced sleep endoscopy (DISE). Methods Prospective cohort study. Patients with OSA underwent two separate DISE examinations. The following outcomes were measured: a global assessment of obstruction at the palate and/or hypopharynx; the degree of obstruction at the palate and hypopharynx; and contribution of individual structures (palate, tonsils, tongue, epiglottis, and lateral pharyngeal walls) to obstruction. Results 32 patients underwent two separate DISE examinations. The apnea-hypopnea index was 40.7±21.1, and the lowest oxygen saturation was 79.8±17.4%. Point estimates for the intraclass correlation coefficient analogs related to palatal obstruction ranged from 0.41-0.89; related to the hypopharyngeal airway, the point estimates ranged from 0.57-0.84. Conclusion The test-retest reliability of DISE appears good, especially in the evaluation of the hypopharyngeal airway. Larger studies can generate more-precise confidence interval estimates and test the generalizability of these findings.

“…Sleep endoscopy was first described in 1991 by Croft and Pringle [12]. Since then, many studies have shown sleep endoscopy to be a safe and useful tool in the evaluation of the upper airway obstruction [14–16].…”

“…Sleep endoscopy has been previously described in the adult and pediatric populations for the purpose of evaluating the dynamic airway in the supine position during a sleep-like state [6, 12, 13]. It is an increasingly useful tool in the evaluation of children with persistent OSA after initial therapy, children with OSA without tonsil or adenoid hypertrophy, or children with significant craniofacial anomalies.…”

Sleep Endoscopy in the Evaluation of Pediatric Obstructive Sleep Apnea

Pediatric obstructive sleep apnea (OSA) is not always resolved or improved with adenotonsillectomy. Persistent or complex cases of pediatric OSA may be due to sites of obstruction in the airway other than the tonsils and adenoids. Identifying these areas in the past has been problematic, and therefore, therapy for OSA in children who have failed adenotonsillectomy has often been unsatisfactory. Sleep endoscopy is a technique that can enable the surgeon to determine the level of obstruction in a sleeping child with OSA. With this knowledge, site-specific surgical therapy for persistent and complex pediatric OSA may be possible.

“…Accurately identifying the main source of snoring sound is important for surgical success [9]. DISN was first described by Croft and Pringle [10] in 1991, and this procedure allows a direct visualization of the sites of vibration or obstruction in a sleeping patient. Compared with the routine clinical examinations while the patient is awake, DISN is considered to be of special value in upper airway evaluation and treatment selection for patients with either SS or OSAS.…”

Objective: To investigate the source of snoring sound in patients with simple snoring (SS) and different degrees of obstructive sleep apnea syndrome (OSAS) in order to provide a basis for the surgical treatment of snoring. Methods: Fifty-two patients with either SS or OSAS (with an apnea-hypopnea index ≤40) underwent drug-induced sleep nasendoscopy (DISN). Vibration sites in the pharyngeal cavity were observed. Results: Vibration of the soft palate, pharyngeal lateral wall, epiglottis, and tongue base appeared in 100, 53.8, 42.3, and 26.9% of the patients, respectively. The source of snoring sound was divided into two types: palatal fluttering only (type I) and multisite vibration (type II). The latter was divided into 3 subtypes: palatal fluttering with epiglottis vibration (type II_a), palatal fluttering with lateral wall vibration (type II_b), and palatal fluttering with vibration of the lateral wall, epiglottis, and tongue base together (type II_c). The distribution of type I snoring was the highest in SS patients. Type II_b was more common in patients with medium and severe OSAS. Type II_c was most common in patients with severe OSAS. Conclusion: The source of snoring sound is diverse, with SS and OSAS patients showing different features. DISN is a very effective method of identifying the snoring source.
