We provide expansion hyoidthyroidpexy as a novel surgical procedure for obstructive sleep apnea (OSA) that could combine different techniques of hyoid bone surgery in 1 procedure. This case series included patients with OSA who had an apnea-hypopnea index (AHI) >15 and showed predominant lateral wall hypopharyngeal collapse. In 21 patients, the procedure was performed smoothly without technical difficulties or operative adverse events, resulting in lateral expansion of each horn of the hyoid bone by ≥1 cm without early or late complications. At 6 months postoperatively, both AHI and the mean lowest oxygen saturation level were significantly improved ( P < .0001). The new expansion hyoidthyroidpexy technique is a reliable, easy, and effective procedure with good surgical outcomes in patients with OSA. It is feasible to be employed in the protocol of multilevel surgery for OSA.

Objective A surgical response to upper airway (UA) surgery for obstructive sleep apnea (OSA) depends on adequate correction of collapsible sites in the UA. This pilot study aimed to examine the surgical response to UA surgery directed by drug-induced sleep computed tomography (DI-SCT) for OSA. Study Design Prospective case series. Setting Tertiary referral center. Subjects and Methods This study recruited 29 OSA patients (median age, 41 years; median body mass index, 26.9 kg/m2) who underwent single-stage DI-SCT-directed UA surgery between October 2012 and September 2014. DI-SCT was performed with propofol for light sedation with a bispectral monitor before and after UA surgery. Nonresponders were defined as those with a reduction in apnea-hypopnea index <50% after 6 months following UA surgery. Results DI-SCT showed that 28 (97%) patients had collapses at multiple sites, all of whom underwent multilevel UA surgery accordingly. The apnea-hypopnea index decreased from 53.6 to 26.8 ( P < .001). There were 18 (62%) nonresponders and 11 (38%) responders. Multiple-site collapses could not predict surgical response ( P > .99). The nonresponders had significant improvements in velopharyngeal, oropharyngeal lateral wall, and tongue collapses (all P < .05), whereas the responders had significant improvements in velopharyngeal and oropharyngeal lateral wall collapses (both P ≤ .05). Conclusion Despite multilevel OSA surgery, residual UA obstruction in nonresponders likely occurs due to multiple mechanisms. DI-SCT may help to elucidate the reasons for a nonresponse.

AbstractThe aim of this study was to assess associations between fat pad areas at various anatomic levels and the sites of lateral wall collapse and disease severity in adult patients with obstructive sleep apnea (OSA). Forty-one patients with OSA who prospectively underwent drug-induced sleep computed tomography were included. Areas of parapharyngeal fat pads and degrees of lateral wall collapse at three representative anatomic levels (nasopharynx, oropharynx, and subglosso-supraglottis), and apnea-hypopnea index (AHI) were measured. In the subglosso-supraglottic region, the parapharyngeal fat pad area in 17 (41%) patients with complete lateral wall collapse was significantly larger than that in 24 (59%) patients without complete collapse (median, 236.0 mm2 vs 153.0 mm2; P = 0.02). In multivariate regression analysis, the parapharyngeal fat pad area at the subglosso-supraglottic level (β = 0.02; P = 0.01) and body mass index (β = 3.24; P = 0.01) were independently associated with AHI. Our preliminary results supported that parapharyngeal fat pads at the subglosso-supraglottic level may be involved in the development of lateral wall collapse and then determine the severity of OSA. Further studies are warranted to investigate the effect of reducing parapharyngeal fat pads in the treatment of OSA.

Objective To examine the effects of multilevel sleep surgery, including palate procedures, on obstructive sleep apnea parameters in the pediatric population. Study Design A case series with chart review was conducted to identify nonsyndromic, neurologically intact pediatric patients who underwent either uvulectomy or uvulopalatopharyngoplasty as part of multilevel sleep surgery from 2011 through 2017. Setting A tertiary care, university children’s hospital. Subjects and Methods Unpaired Student t test was used to compare average pre- and postsurgical apnea-hypopnea index (AHI) and oxygen saturation nadir (OSN). Paired Student t test was used to compare the mean pre- and postsurgical AHI and OSN within the same patient for the effects of adenotonsillectomy (T&A) vs multilevel sleep surgery. Results In patients who underwent T&A previously, multilevel sleep surgery, including palate procedures, resulted in improved OSA severity in 6 (86%) patients and worsened OSA in 1 (14%) patient. Multilevel sleep surgery, including palate procedures, significantly decreased mean AHI from 37.98 events/h preoperatively to 8.91 events/h postoperatively ( P = .005). However, it did not significantly decrease OSN. Conclusion This study includes one of the largest populations of children in whom palate procedures as a part of multilevel sleep surgery have been performed safely with no major complications and a low rate of velopharyngeal insufficiency. Therefore, palatal surgery as a part of multilevel sleep surgery is not necessarily the pariah that we have traditional thought it is in pediatric otolaryngology.

ObjectiveLaryngomalacia has been reported to contribute to the severity of obstructive sleep apnea (OSA) in children. It is unclear if surgical treatment of laryngomalacia improves polysomnography (PSG) outcomes in these patients. The objective of this study is to report the impact of supraglottoplasty on PSG parameters in children with laryngomalacia-related OSA.Study DesignRetrospective case series.SettingTertiary care medical center.Subjects and MethodsHistorical cohort study of consecutive children with laryngomalacia who underwent supraglottoplasty and who had undergone overnight PSG before and after surgery.ResultsForty-one patients were included in the final analysis: 22 (53.6%) were male, and 19 (46.3%) were female. The mean ± SEM age of patients at preoperative PSG was 1.3 ± 0.89 years (range, 0.003-2.9). In entire cohort, the mean obstructive apnea-hypopnea index score was reduced from 26.6 events/h before supraglottoplasty to 7.3 events/h after surgery ( P = .003). Respiratory disturbance index was reduced from 27.3 events/h before supraglottoplasty to 7.8 events/h after surgery ( P = .003). The percentage of REM sleep decreased from 30.1% ± 2.4 to 24.8% ± 1.3 ( P = .04). Sleep efficiency was improved ( P = .05).ConclusionOverall, supraglottoplasty significantly improved several PSG outcomes in children with laryngomalacia. However, mild to moderate OSA was still present postoperatively in most children. This suggested a multifactorial cause for OSA in this population.

Objective Positional obstructive sleep apnea (POSA)—defined as obstructive sleep apnea twice as severe supine than nonsupine—may offer clues to the underlying pattern of upper airway collapse in children. We compared drug-induced sleep endoscopy (DISE) findings in children with and without POSA. We hypothesized that children with POSA would have significantly higher obstruction at the gravity-dependent palate and tongue base but not at the adenoid, lateral wall, or supraglottis. Study Design Retrospective case series. Setting Tertiary pediatric hospital. Subjects and Methods We included children aged 1 to 12 years with obstructive sleep apnea diagnosed by polysomnography who underwent DISE from July 2014 to February 2019. Scores were dichotomized as ≥50% obstruction (Chan-Parikh 2 or 3) vs <50% obstruction (Chan-Parikh 0 or 1). Results Of 99 children included, 32 (32%) had POSA and 67 (68%) did not. Children with POSA did not differ from children without POSA in age, overall apnea-hypopnea index, sex, race, syndromic diagnoses, obesity, or history of adenotonsillectomy. In logistic regression models, odds of ≥50% obstruction were significantly higher at the tongue base (odds ratio, 2.77; 95% CI, 1.04-7.39) after adjustment for age, sex, obesity, previous adenotonsillectomy, and syndrome. No difference was noted at the adenoid, velum, lateral wall, or supraglottis. Conclusion POSA was associated with higher odds of obstruction on DISE at the tongue base but not at other levels.

Objectives To evaluate demographic, clinical, and polysomnographic features of children with Down syndrome suspected of having obstructive sleep apnea. To identify factors that predict severe obstructive sleep apnea among children with Down syndrome. Study Design Case series with chart review. Setting Children’s Medical Center Dallas / University of Texas Southwestern Medical Center. Subject and Methods Demographic, clinical, and polysomnographic data were collected for children with Down syndrome aged 2 to 18 years. Simple and multivariable regression models were used to study predictors of severe obstructive sleep apnea (apnea-hypopnea index ≥10). P≤ .05 was considered significant. Results A total of 106 children with Down syndrome were included, with 89 (84%) <12 years old, 56 (53%) male, 72 (68%) Hispanic, 15 (14%) African American, and 14 (13%) Caucasian. Ninety percent of children had ≥1 medical comorbidities; 95 (90%) patients had obstructive sleep apnea; and 46 (44%) had severe obstructive sleep apnea. The mean SaO2 nadir was lower among obese than nonobese children (80% vs 85%, P = .02). Obese versus nonobese patients had a higher prevalence of severe obstructive sleep apnea (56% vs 35%, P = .03). Severe OSA was associated with heavier weight (odds ratio = 1.0, 95% CI: 1.0-1.1, P = .002) and age ≥12 years (odds ratio = 1.2, 95% CI: 0.2-2.5, P = .02). The multivariable model showed that severe obstructive sleep apnea was associated only with weight (odds ratio = 1.1, 95% CI: 1.0-1.1, P = .02). Conclusion Obese children with DS are at a high risk for severe OSA, with weight as the sole risk factor. The results of this study show the importance of monitoring the weight of children with DS and counseling parents of children with DS about weight loss.

Objective: To explore the feasibility, outcomes, and factors affecting the outcome of Z-palatopharyngoplasty (ZP3) in the treatment of severe obstructive sleep apnea/hypopnea syndrome (OSAHS). Study Design: Case series with chart review. Methods: ZP3 was performed on 34 Friedman stage II/III OSAHS patients with a posterior airway space (PAS) ≥ 11 mm. Postoperative follow-up was at least 6 months, and the differences between responders and nonresponders were analyzed. Results: On the basis of success criteria, defined as an apnea-hypopnea index < 20 and a decrease > 50 percent, the success rate was 64.7 percent. The lowest oxygen saturation (LSaO2), percentage of time with an oxyhemoglobin saturation below 90 percent (CT90), mandibular plane angle (MPA), mandibular body length, position of the tongue, and Friedman clinical stage differed significantly between responders and nonresponders. The logistic regression analysis showed that MPA and Friedman stage were the key predictors of ZP3 surgical success. The best cutoff points for LSaO2, CT90, and MPA were 72 percent, 22.80 percent, and 29.40°, respectively. Conclusions: Factors affecting the outcome of ZP3 included LSaO2, CT90, MPA, mandibular body length, position of the tongue, and Friedman clinical stage. Of these, the MPA and Friedman clinical stage were most influential.

Objective: To compare the retrolingual obstruction during drug-induced sleep endoscopy (DISE) with the retrolingual obstruction during polysomnography with nasopharyngeal tube (NPT-PSG). Methods: A cross-sectional study of 77 consecutive patients with moderate and severe obstructive sleep apnea (OSA) was conducted. After 15 patients were excluded from the study for not completing DISE or NPT-PSG successfully, 62 patients were included in this study. Retrolingual sites of obstruction grade 2 determined by DISE according to the VOTE (velum, oropharynx lateral wall, tongue base, and epiglottis) classification were considered as retrolingual obstruction, while apnea-hypopnea index (AHI) ≥ 15 events/hour determined by NPT-PSG was considered as retrolingual obstruction. The extent of agreement between DISE and NPT-PSG findings was evaluated using unweighted Cohen’s kappa test. Results: The 62 study participants (11 moderate OSA, 51 severe OSA) had a mean (SD) age of 39.8 (9.9) years, and 58 (94%) were men. No statistically significant differences between included and excluded patients were observed in patient characteristics. The extent of agreement in retrolingual obstruction between DISE and NPT-PSG was 80.6% (Cohen k = 0.612; 95% CI, 0.415-0.807). Conclusion: Retrolingual obstruction requiring treatment showed good agreement between DISE and NPT-PSG, suggesting that NPT-PSG may also be a reliable method to assess the retrolingual obstruction.

Objective The primary objective was to determine if obstructive sleep apnea (OSA) can improve after adenoidectomy. Study Design Case series with chart review. Setting Tertiary children’s hospital between 2016 and 2018. Methods The study included children under 3.5 years with small (1+ or 2+) palatine tonsils, large (3+ or 4+) adenoids, and documented OSA on polysomnogram (PSG). Results Seventy-one children were included. Age at adenoidectomy was 2.0 years (95% CI, 1.8-2.2) and 71.8% were male. Mean follow-up was 2.5 years (95% CI, 2.3-2.7). Twenty-six children (36.6%) obtained a repeat PSG at a mean of 9.7 months (95% CI, 6.3-13.2) after adenoidectomy. Among those with a postoperative PSG, apnea-hypopnea index decreased in 77.0% (mean, –3.2 events/h; 95% CI, –14.1 to 7.6), and the proportion with moderate to severe OSA decreased from 65.4% to 30.8% ( P = .03). Six children (23.1%) had a normal PSG after adenoidectomy. Tonsillectomy was performed in 14.1% of children at 12.1 months (95% CI, 7.5-16.7) after adenoidectomy. Despite similar preoperative PSG variables, younger children (1.5 vs 2.1 years, P = .02) were more likely to require tonsillectomy. Substantial adenoid regrowth was identified in 1 child at the time of tonsillectomy. Conclusion Adenoidectomy may improve OSA in young children with large adenoids and small tonsils. However, younger age predicted the need for subsequent tonsillectomy. Prospective studies with additional PSG data are necessary to corroborate these findings.
