Abstract
BACKGROUND The purpose of this study was to evaluate the comparative incidence of obstructive sleep apnea following velopharyngeal insufficiency surgery in the United States. METHODS A retrospective analysis of cleft and noncleft pediatric patients who underwent velopharyngeal insufficiency surgery was performed using the IBM MarketScan Commercial Database. Patients were tracked longitudinally from 2007 to 2016 to evaluate the incidence of obstructive sleep apnea. Multivariable regression was used to evaluate predictors of postoperative obstructive sleep apnea and surgical revision. RESULTS A total of 1098 patients underwent a pharyngeal flap (61.0 percent), sphincter pharyngoplasty (22.2 percent), or palatal lengthening with or without island flaps (16.8 percent). Diagnoses were predominantly cleft lip and/or palate (52.8 percent) and congenital oropharyngeal anomalies (42.6 percent). Eighty patients (7.3 percent) developed obstructive sleep apnea at an average of 10.2 months postoperatively. Predictors of obstructive sleep apnea included older age (p = 0.014) and head and neck neoplasm (p = 0.011). The obstructive sleep apnea rate following sphincter pharyngoplasty was 11.1 percent, compared to 7.2 percent after pharyngeal flap surgery. Compared to sphincter pharyngoplasty, pharyngeal flap surgery was associated with a lower risk of further surgery (OR, 0.43; p = 0.010). Of patients with cleft lip and/or palate, 35 developed obstructive sleep apnea (6.0 percent) without a significant association with procedure type. CONCLUSIONS In this national claims database analysis of cleft and noncleft pediatric patients, the rate of obstructive sleep apnea following velopharyngeal insufficiency surgery was not significantly different for pharyngeal flap compared to sphincter pharyngoplasty. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, III.

Abstract
PURPOSE OF REVIEW Submucous cleft palate (SMCP) represents an uncommon congenital palatal anomaly with a variable rate of velopharyngeal dysfunction or resulting speech abnormality. Classic teaching regarding management of this entity involves delayed repair until a perceptual speech assessment by a skilled speech-language pathologist can be performed, typically at age 3-5 years. An assessment of timing of intervention, surgical techniques, and patient comorbidities is critical for optimized outcomes. RECENT FINDINGS Early diagnosis and surgical intervention for SMCP are associated with improved speech outcomes. Expanding indications for surgery are being actively investigated. Timing of intervention and surgical technique may be influenced by a syndromic diagnosis, specifically 22q11.2 deletion syndrome. SUMMARY Diagnosis of classic SMCP and occult SMCP may be difficult based on provider experience. Variable surgical techniques may be used with good outcomes; patient comorbidities including syndromic diagnoses may determine best surgical technique. Expanding indications for surgery and timing of repair continue to evolve and warrant additional study.

Abstract
BACKGROUND Obstructive sleep apnea is a disorder of repetitive complete or partial airway obstruction during sleep. The aim of this study was to assess the impact of alveolar cleft reconstruction on the obstructive sleep apnea (OSA) condition and apnea/hypopnea index (AHI). METHODS In a double-blinded prospective quasi-experimental study, all healthy systemic children (n=30 female cleft patients) with unilateral alveolar cleft defects within the age range of 8-14 years and BMI less than 30 kg/m2 who admitted for alveolar cleft repair were enrolled. OSA monitoring was performed one week before surgery, and 3 months postoperatively by Apnea Link device. Sleep apnea indices such as AHI, respiratory disturbance index (RDI), oxygen desaturation index (ODI) and oxyhemoglobin saturation (SpO2) as well as pulse rate (PR) and respiratory rate (RR) were the variables. RESULTS The patients’ mean age was 11.0±1.4 years, and BMI average was 21.48±4.4 kg/m2. Mean AHI was 21.6±5.0 events/hour, preoperatively; which decreased significantly and reached 4.4±2.5 events/hour after alveolar cleft reconstruction surgery (p=0.005). Moreover, the other OSA variables (SpO2, RDI, and ODI), as well as vital signs (PR, and RR) improved postoperatively (p=0.005). In other words, the preoperative moderate OSA status relieved after alveolar cleft repair and reconstruction. CONCLUSION Our study showed that the OSA and AHI ameliorated after bone graft surgery in alveolar cleft repair. More clinical trials including larger sample sizes may be required for relevancy.

Abstract
Objectives: (1) To assess the evolution of prepalatoplasty sleep oximetry (PRESO) and postpalatoplasty sleep oximetry (POSSO) in cleft patients and (2) to evaluate the impact of the size of the nasopharynx on PRESO and POSSO values. Study Design: Retrospective cohort study. Patients and Methods: In 81 patients with cleft palate and/or cleft lip, the following data were prospectively collected: patient demographics and prepalatoplasty cleft palate measurements. All the patients had at least 1 PRESO and POSSO. A Kaplan-Meier curve was obtained from all the sleep oximetry results. Transverse nasopharyngeal area (TNA) pre- and postvalues were compared for each group with paired t tests, while analysis of variance was used to compare TNA pre- and postscores between the groups with a Bonferroni correction for multiple comparisons. Results: POSSO results were normal or showed mild desaturations in most patients in the few weeks following palatoplasty. For the cohort, no statistically significant changes were found between PRESO and POSSO values. A 2-fold variation in the area of the TNA was found before palatoplasty within identical cleft malformation cases. No statistically significant association was found between the TNA or the a/30 − b 1 parameter values and the sleep study scores. Conclusions: The patients with the smaller nasopharyngeal areas presented identical PRESO and POSSO results when compared to those with larger nasopharyngeal sizes. Future studies should address the possible association between prepalatoplasty and postpalatoplasty TNAs and the occurrence of velopharyngeal deficiency later in life.

Abstract
OBJECTIVE To compare the prevalence of increased risk of obstructive sleep apnea (OSA) in children with and without cleft lip and/or palate using a previously validated questionnaire and to examine the clinical and demographic variables that may lead to increased OSA risk. DESIGN Prospective, cross-sectional study. PARTICIPANTS One hundred fifty-five cleft lip palate and 155 noncleft children between 2 and 18 years old. INTERVENTIONS The Pediatric Sleep Questionnaire (PSQ): Sleep Related Breathing Disorder Scale was used for screening of increased OSA risk. Age, body mass index (BMI), gender, breast-feeding, and bottle-feeding durations were recorded for all patients. Cleft type, lip and palate operation times, nasoalveolar molding, or nutrition plaque usage was documented for the cleft lip palate group. Pearson χ2 or Fisher exact test was used for the evaluation of the qualitative variables and independent samples t test or Mann Whitney U test for quantitative variables. P < .05 was accepted as statistically significant. RESULTS The mean ages were 7.52 ± 3.91 and 7.50 ± 3.89 years for cleft lip palate and control groups, respectively. No significant differences were observed between the groups for age, gender, or BMI. Breast-feeding duration was significantly higher, and bottle-feeding duration was lower in the control group (P < .05). Mean PSQ score was significantly higher in cleft lip palate group (0.18 ± 0.12) than in control group (0.13 ± 0.1, P < .001); and prevalence of increased OSA risk was significantly higher in patients with both cleft lip and palate (P = .020). CONCLUSIONS Positive OSA screening ratio of children with cleft lip and palate (12.2%) was significantly higher than the controls (4.5%).

Abstract
BACKGROUND Sleep disordered breathing (SDB) is defined as a series of disorders including snoring, obstructive sleep apnea, and hypopnea. Few studies investigated the incidence of SDB following primary palatoplasty with objective testing. The aims of this study were to elucidate the prevalence and degree of SDB approximately 1 week following primary palatoplasty with objective testing and to clarify the risk factors. METHOD A retrospective review was performed on children who underwent primary palatoplasty between April 2013 and July 2017 at National Center for Child Health and Development, Tokyo, Japan. As a national center, the authors accept many syndromic patients. The authors keep all patients after palatoplasty intubated and observe them overnight in intensive care unit to reduce the risks of respiratory events. Patients were evaluated with overnight pulse oximetry on 5 to 7 days postoperatively. RESULTS Forty-four patients were included, and 30% of the patients were associated with congenital anomaly. Thirteen patients (30%) were diagnosed with SDB. None of the patients required additional treatment after the evaluation. Laryngomalacia and postoperative oxygen requirement significantly correlated with postoperative SDB. CONCLUSION Approximately one-third of the patients may be at the risk of SDB 1 week after primary palatoplasty. Patients with history of laryngomalacia or those who required oxygen support for prolonged time after primary palatoplasty should be cared for significantly high risk of postoperative SDB.

Abstract
OBJECTIVE To determine if sphincter pharyngoplasty changes sleep study parameters on patients undergoing surgery for velopharyngeal insufficiency (VPI). DESIGN Retrospective chart review on patients undergoing sphincter pharyngoplasty for VPI with pre- and postoperative polysomnography completed. SETTING Institutional study at a tertiary pediatric hospital. PATIENTS All patients who underwent sphincter pharyngoplasty over a 20-year period were reviewed; all patients with both pre- and postoperative sleep studies were collected for evaluation. INTERVENTIONS Sphincter pharyngoplasty for patients with VPI. MAIN OUTCOME MEASURE Sleep study parameters collected include apnea-hypopnea index (AHI), obstructive and central apneas, hypopneas, and mixed events. The preoperative values were compared to postoperative values. RESULTS There were 98 patients collected with sleep studies for review. Of these, 32 patients had both pre- and postoperative sleep studies. The AHI increased from 1.8 preoperatively to a postoperative value of 4.8 ( P = .004). The number of obstructive events per night went from 4.6 to 17.6 postoperatively ( P = .04). The number of hypopneas increased from 4.0 to 13.6 ( P = .003). The other parameters were not statistically different, central events decreased from 4.8 to 2.1 ( P = .086), and mixed events were essentially unchanged from 0.2 to 0.5 ( P = .17) events per night. CONCLUSIONS Patients undergoing sphincter pharyngoplasty for VPI may experience an increase in their postoperative AHI, obstructive events per night, and hypopneas. Sleep studies should be performed both pre- and postoperatively to assess the need for intervention or change in management.

Abstract
OBJECTIVE To prospectively investigate the occurrence of respiratory symptoms related to obstructive sleep apnea (OSA) following primary palatoplasty in children with cleft palate (CP). METHOD Fifty-six nonsyndromic children presenting CP with a previously repaired cleft lip (CL) or without CL were assessed before and after palate repair. Twenty nonsyndromic children with isolated CL were analyzed as controls before and after lip repair. Respiratory symptoms were investigated preoperatively, and at early and late postoperative periods. Based on the parent reports of "difficulty of breathing (D), apnea events (A) and/or snoring (S) during sleep, a validated OSA index (1.42D + 1.41A + 0.71S - 3.83) was used to predict absence of OSA, possible OSA, and presence of OSA, at the 3 periods analyzed. RESULTS Screening for OSA showed that the CP group exhibited an increased mean index at the early postoperative assessment, suggesting "possible OSA," and a higher frequency of snoring at the early and late postoperative assessments, as compared to the CL group (P < .05). Sleep apnea events were not reported. CONCLUSIONS Surgical closure of the palate has an obstructive effect on the upper airway in the short term, causing OSA-related respiratory symptoms, mostly transient. However, the high prevalence of snoring still observed in the long term indicate that children with a palatal cleft who undergo surgical repair are at risk for OSA. The results support the conclusion that OSA is underappreciated in this population.

Abstract
Cleft lip and palate (CLP) is the most common congenital craniofacial abnormality. Obstructive sleep apnea syndrome (OSAS) is a highly prevalent but underdiagnosed disease and is frequently associated with craniofacial anomalies. There are few studies describing the sleep breathing pattern of children with CLP. This study sought to characterize the respiratory profile of 23 children with unilateral cleft lip and palate, aged 7-12 years, who had undergone cleft lip and nasal repair at age 3-4 months and palatoplasty at 12-15 months, with a particular focus on evaluating the presence of OSAS in children with CLP. Polysomnography was performed and findings were analyzed descriptively. We found a mean and median for apnea/hypopnea index (AHI) of 1.11/h (SD = 0.78) and 0.9/h, respectively. The mean obstructive apnea index (OAI) was 0.27/h (SD = 0.38) and the median, 0.1/h. Nearly 30% of patients had an AHI above 1.4 events/h. There was no significant oxyhemoglobin desaturation in the study group. In this group, the prevalence of OSAS was higher than in noncleft populations when compared to the normality values adopted. This sample of patients with unilateral cleft lip and palate exhibited an increased prevalence of OSAS during the mixed dentition stage. Although the results showed that OSAS was mild, we advise closer observation of these patients. Polysomnography is recommended for the assessment of children with airway abnormalities, to individualize the extent of treatment.

Abstract
Cleft lip and palate is the most common congenital craniofacial anomaly. Up to 60% of these patients will benefit from cleft orthognathic surgery, which consists primarily of maxillary advancement and mandibular setback to address midface retrusion and relative mandibular protrusion, respectively. It is believed that maxillary advancement can enlarge the airway whilst mandibular setback can reduce the airway, but this has not previously been quantified for cleft patients undergoing orthognathic surgery. This unique longitudinal prospective study of 18 patients was conducted between April 2013 and July 2016. No significant changes occurred by six months postoperatively in body mass index, apnoea-hypopnoea index or lowest oxygen saturation (LSAT). There was a mean increase of 0.73 cm3 in velopharyngeal volume, a mean decrease of 0.79 cm3 in oropharyngeal volume, an improvement in snoring index, and no statistically significant change in hypopharyngeal volume. In conclusion, cleft orthognathic surgery that produced anterior advancement of the maxilla, setback of the mandible and clockwise rotation of the maxillo-mandibular complex resulted in increased velopharyngeal, decreased oropharyngeal and unchanged hypopharyngeal airways, and improved snoring, but did not significantly alter objective sleep-related breathing function.

Abstract
OBJECTIVE To determine whether the clinical presentation or severity of sleep disordered breathing differs between children with or without a history of cleft lip and/or palate (CL/P) presenting for sleep assessment. DESIGN Retrospective chart review. SETTING Tertiary care pediatric hospital cleft clinic, sleep clinic. PATIENTS Children >6 months of age presenting to the cleft clinic with sleep concerns and children without CL/P presenting to the sleep clinic in the same 2-year period. MAIN OUTCOMES MEASURES Clinical symptoms and overnight polysomnography (PSG) results. RESULTS A total of 168 children (55 from cleft clinic, 113 from sleep clinic) were identified. Age at clinical review (6.6 ± 4.1 years versus 6.8 ± 4.0 years, P = ns), sex distribution (64.6% versus 58.4%, P = ns), and the presence of syndromes or significant medical conditions (12% versus 16%, P = ns) were similar between groups. Snoring was the reason for referral in 59% of children with CL/P and 69% of non-CL/P children (P = ns). The only presenting feature that differentiated between the groups was a lower incidence of tonsillar enlargement in children with CL/P (33% versus 79%, chi-square 30.4, P < 0.001). Sleep study results showed similar apnea-hypopnea indices (6.2 ± 6.9 versus 7.9 ± 7.1 events/hr, P = ns) with more central apnea in children with CL/P (1.5 ± 1.5 versus 1.0 ± 1.0 events/hr, P = 0.017). CONCLUSIONS Snoring and obstructive sleep apnea are common in CL/P with less tonsillar enlargement than non-CL/P children. Children with CL/P have similar OSA severity compared to non-cleft children but more central apnea which may indicate differences in the control of breathing.

Abstract
Obstructive sleep apnoea syndrome (OSAS) is common in children. Craniofacial anomalies such as cleft palate are among the most common congenital conditions. Children with a variety of craniofacial conditions, including cleft palate, micrognathia, craniosynostosis, and midface hypoplasia are at increased risk for OSAS. Available evidence, which is largely limited to surgical case series and retrospective studies, suggests that OSAS can be successfully managed in these children through both surgical and non-surgical techniques. Prospective studies using larger cohorts of patients and including polysomnograms are needed to better understand the risk factors for this patient population and the efficacy of treatment options for OSAS and their underlying conditions.

Abstract
STUDY OBJECTIVES Obstructive sleep symptoms are common in children with craniofacial malformations (CFM). However objective data about obstructive sleep apnea (OSA) is still limited. The aims of this study were to investigate the frequency of OSA in symptomatic children with CFM and to determine improvement in severity of OSA after treatment. METHODS Symptomatic children with CFM referred for a diagnostic polysomnogram (PSG) were identified. Obstructive sleep apnea was defined as an apnea/hypopnea index (AHI) ≥ 1, with moderate/severe OSA as an AHI ≥ 5. RESULTS Overall, 151 symptomatic children were identified; 87% were diagnosed with OSA, of whom 24% had moderate-to-severe OSA. Children with syndromic CFM, compared to non-syndromic CFM, were more likely to have an AHI ≥ 5 (syndromic 33% vs. non-syndromic 15%, p = 0.02). Of the 131 children with OSA, 64 were treated and 32 returned for a posttreatment PSG, with 22 treated with either positive airway pressure (PAP) or adenotonsillectomy (AT). Children treated with PAP demonstrated a decrease in AHI from 6.2 to 3.5 (p = 0.057) and an increase in SpO2 from 89.1% to 91.1% (p = 0.091). There were no significant improvements for those in the AT group for either AHI (2.5 to 1.8, p = 0.19) or SpO2 (90.4% to 91.3%, p = 0.46). Normalization of the AHI (AHI < 1) occurred in only one child in each group (7% and 14% of the PAP and AT groups, respectively). CONCLUSIONS The vast majority of children with CFM referred for OSA evaluation are found to have objective evidence of OSA and a quarter of children have moderate-to-severe OSA. It is likely that many children with underlying OSA are not identified and referred for evaluation. Residual OSA after treatment is common in children with CFM.

Abstract
STUDY OBJECTIVE The purpose of this study was to investigate the frequency of sleep disordered breathing (SDB) symptoms in a clinical sample of children with congenital craniofacial malformations (CFM) followed at a tertiary medical center and non-selected for sleep problems. METHODS Cross-sectional study of 575 children aged 2-18 years followed at the Craniofacial Anomalies Program between March 2007 and May 2011. The Sleep-Related Breathing Disturbance scale of the Pediatric Sleep Questionnaire was used to screen for SDB, snoring, and sleepiness. A cutoff value ≥ 0.33 of the total answered questions identified children with positive screening for SDB symptoms. RESULTS Overall, 25% of children screened positive for SDB, 28% for snoring, and 20% for sleepiness. In children with non-syndromic CFM, those with Robin sequence had the highest frequency of SDB, snoring, and sleepiness (43%, 44%, and 38%, respectively). In children with syndromic CFM, velocardiofacial/ DiGeorge syndrome had the highest frequency of SDB and sleepiness (48% and 43%, respectively). Children with Treacher Collins had the highest frequency of snoring (83%). The presence of cleft palate was not associated with an increased frequency of SDB symptoms. Nevertheless, children with syndromic CFM, compared to those with non-syndromic CFM, had a higher SDB score (0.27 ± 0.21 vs.0.21 ± 0.19, p = 0.003) and were more likely to have sleepiness (26% vs. 18%, p = 0.05). CONCLUSIONS Congenital craniofacial malformations in children are associated with high risk for SDB symptoms. Our findings should encourage a high index of suspicion for SDB in children with CFM, with a low threshold for further testing and close follow-up.

Abstract
OBJECTIVES : To determine whether Sommerlad palate re-repairs and Hynes pharyngoplasties cause obstructive sleep apnea/hypopnea or increased upper airway resistance. DESIGN : Prospective before-and-after study. SETTING : Tertiary cleft unit. PATIENTS : A total of 44 patients undergoing a Sommerlad palate re-repair or a Hynes pharyngoplasty. Interventions : Preoperative and postoperative multichannel cardiorespiratory sleep studies. MAIN OUTCOME MEASURES : The main outcome measures were mean arterial oxygen saturation, desaturation index, percentage of time spent with arterial oxygen saturation <90%, mean pulse rate, number of pulse rate rises (arousals) per hour, inspiratory effort derived from pulse transit time, pulse transit time arousals, and snoring. RESULTS : No patient in either group required intervention for airway obstruction or obstructive sleep apnea/hypopnea. Re-repairs caused no significant change in any parameter. Hynes caused an increase in inspiratory effort (P = .04) and obstructive sleep apnea/hypopnea grading (P = .002). All other parameters showed no significant deterioration. No patient developed more than mild/moderate obstructive sleep apnea/hypopnea. Snoring and arterial oxygen saturation levels were not reliable indicators of increased inspiratory effort. CONCLUSIONS : A palate re-repair had no significant adverse effect on the airway. A Hynes, in patients with optimized velar function, caused a significant increase in inspiratory effort and obstructive sleep apnea/hypopnea grade. However, compared with studies on midline flaps and on sphincter pharyngoplasties, a Hynes appears to be less obstructive. Failure to study changes in inspiratory effort in patients undergoing velopharyngeal incompetence surgery may underestimate the obstructive effect of pharyngoplasties.

Abstract
OBJECTIVE This comprehensive, evidence-based review provides a systematic analysis of the literature regarding the validity, reliability, and clinical utility of polysomnography for characterizing breathing during sleep in children. Findings serve as the foundation of practice parameters regarding respiratory indications for polysomnography in children. METHODS A task force of content experts performed a systematic review of the relevant literature and graded the evidence using a standardized grading system. Two hundred forty-three evidentiary papers were reviewed, summarized, and graded. The analysis addressed the operating characteristics of polysomnography as a diagnostic procedure in children and identified strengths and limitations of polysomnography for evaluation of respiratory function during sleep. RESULTS The analysis documents strong face validity and content validity, moderately strong convergent validity when comparing respiratory findings with a variety of relevant independent measures, moderate-to-strong test-retest validity, and limited data supporting discriminant validity for characterizing breathing during sleep in children. The analysis documents moderate-to-strong test-retest reliability and interscorer reliability based on limited data. The data indicate particularly strong clinical utility in children with suspected sleep related breathing disorders and obesity, evolving metabolic syndrome, neurological, neurodevelopmental, or genetic disorders, and children with craniofacial syndromes. Specific consideration was given to clinical utility of polysomnography prior to adenotonsillectomy (AT) for confirmation of obstructive sleep apnea syndrome. The most relevant findings include: (1) recognition that clinical history and examination are often poor predictors of respiratory polygraphic findings, (2) preoperative polysomnography is helpful in predicting risk for perioperative complications, and (3) preoperative polysomnography is often helpful in predicting persistence of obstructive sleep apnea syndrome in patients after AT. No prospective studies were identified that address whether clinical outcome following AT for treatment of obstructive sleep apnea is improved in association with routine performance of polysomnography before surgery in otherwise healthy children. A small group of papers confirm the clinical utility of polysomnography for initiation and titration of positive airway pressure support. CONCLUSIONS Pediatric polysomnography shows validity, reliability, and clinical utility that is commensurate with most other routinely employed diagnostic clinical tools or procedures. Findings indicate that the "gold standard" for diagnosis of sleep related breathing disorders in children is not polysomnography alone, but rather the skillful integration of clinical and polygraphic findings by a knowledgeable sleep specialist. Future developments will provide more sophisticated methods for data collection and analysis, but integration of polysomnographic findings with the clinical evaluation will represent the fundamental diagnostic challenge for the sleep specialist.

Abstract
OBJECTIVE To investigate the association between craniofacial anomalies and diagnosis with obstructive sleep apnea (OSA) in a large, population-based sample of children. DESIGN Retrospective case-control study. METHODS Cases of OSA (n = 1,203) were identified by International Classification of Diseases-9 codes consistent with OSA in the 1987-2003 Washington State inpatient discharge database among children ≤18 years of age and born in Washington state. For each case, five controls without OSA (n = 6,015) were randomly selected from the remaining Washington State births, frequency matched by birth year. Congenital anomaly diagnoses and covariates were extracted from discharge data for all inpatient hospitalizations during the study period and linked birth certificate data. Multiple logistic regression was used to calculate adjusted odds ratios (OR) and 95% confidence intervals (CI) for the associations between congenital anomalies (including subgroups) and OSA. RESULTS An OSA diagnosis was strongly associated with the presence of any craniofacial anomaly (adjusted OR 38, 95%CI [24, 60]) and, in particular, with orofacial cleft (adjusted OR 40, 95%CI [17, 94]) and Down syndrome (adjusted OR 51, 95%CI [20, 128]). OSA was less associated with any noncraniofacial malformation (adjusted OR 4.1, 95%CI [3.1, 5.3]), which may reflect the relatively small effect of inpatient exposure bias in the associations above. CONCLUSIONS The presence of congenital craniofacial anomalies is strongly associated with inpatient diagnosis of OSA. These findings persist even after control of major potential biases. Parents and clinicians should consider screening for OSA among children with craniofacial anomalies.

Abstract
Objective: The objective of this study was to explore the prevalence, range of reported symptoms, and clinical risk factors of obstructive sleep apnea in preschool children with cleft lip and/or palate. Design: Questionnaires were distributed to parents/guardians of all children from birth to 5 years of age who were followed by the cleft clinic. Results: Questionnaire data and cleft classification were available for 248 children, with a mean age of 33.4 months. Obstructive sleep apnea was identified in 31.4% of the children. Only 29.5% of children with obstructive sleep apnea had undergone an investigation of these symptoms. The three most common symptoms reported in children with a questionnaire diagnosis of obstructive sleep apnea were (1) “heavy or loud breathing,” (2) “easily distracted,” and (3) “on the go” or “driven by a motor.” The only clinical risk factor associated with a questionnaire diagnosis of obstructive sleep apnea was the presence of a syndrome (χ2 = 3.5, p = .05). There were no significant differences in risk of obstructive sleep apnea by age, cleft classification, and surgical status. Conclusion: Preschool children with cleft lip and/or palate have a risk of obstructive sleep apnea that is as much as five times that of children without cleft. Obstructive sleep apnea appears to be underrecognized in this group of children. Further research is needed to investigate important risk factors for obstructive sleep apnea in children with cleft lip and/or palate.

Abstract
OBJECTIVES/HYPOTHESIS Children with cleft deformities have the tendency for multilevel airway obstruction. The incidence of sleep disordered breathing (SDB) in this population has not been well studied. This study attempts to describe the high incidence and the results of intervention. STUDY DESIGN A three-year retrospective chart review by a tertiary cleft and craniofacial team. METHODS The symptoms of sleep disordered breathing and polysomnographic data were reviewed and analyzed using descriptive statistics and multivariate analysis. RESULTS Of the 539 children seen during the period, 120 (22%) had symptoms suggestive of SDB. Twenty-four of them had a tonsillectomy with or without partial adenoidectomy without polysomnogram (PSG). Sixty-nine (57%) had a PSG, and 28 (40%) had a follow-up PSG. Syndromic children had significantly more symptoms of SDB (P < .001) and were more likely to undergo PSG (P < .05). Of those children who underwent a PSG, only six had a normal obstructive apnea-hypopnea index (OAHI) with a mean (+/-standard deviation) respiratory disturbance index (RDI) of 15.5 (+/-17.5) and OAHI of 12.05 (+/-15.57). Post intervention PSG showed significant improvement in RDI (P = .048) and OAHI (P = .012) using a single-tailed Wilcoxan analysis. Unfortunately, most of these children still had significant sleep apnea. There was also a high percentage of children with periodic leg motion syndrome (24.7%), some of whom also had OSA. CONCLUSION There is a high incidence of SDB and definable OSA in the cleft population. Though there is a statistically significant improvement after intervention, some were not cured. Sleep disturbance and OSA is likely under-reported and treated in the cleft population. PSG should be done more frequently, and post intervention PSG should be strongly considered.

Abstract
BACKGROUND Cleft palate is associated with an increased risk of sleep disordered breathing (SDB) but the magnitude of this risk and specific risk factors are unclear. A better understanding of these components of risk will aid the early identification of SDB in this group of children. OBJECTIVE To describe the clinical characteristics and results of sleep studies undertaken in a cohort of children with cleft palate. Clinical features will be examined to determine potential associations with SDB in this group. METHOD A retrospective chart review was undertaken to ascertain sleep study results and clinical data for all children with cleft palate. Clinical features of interest included age, gender, syndrome diagnosis, cleft classification, and surgical status. RESULTS A total of 99 sleep studies were available from 62 children. The sample included a select group of children with cleft palate with features predictive of a high risk of SDB. Baseline sleep study results were consistent with SDB for 87% of children and 28% (15 of 54) of these children demonstrated severe SDB. Uni-variate analysis showed that age, syndrome, and surgical status had significant association with the severity of SDB. On multi-variate analysis only surgical status maintained this association, such that pre-palatoplasty/pharyngoplasty was associated with more severe SDB. Follow-up studies were completed in one-third of the cohort. CONCLUSION Children with cleft palate appear to have a significant risk of SDB. A prospective study of a population of children with cleft palate is needed to further define the characteristics of this risk and important risk factors.

Abstract
Sleep apnea in craniofacial surgery was investigated. Between January 1999 and December 2003, 18 patients were measured at an at least 6-month interval before and after surgery. Eight patients underwent palatoplasty for cleft palate, and the other 10 patients underwent orthognathic surgery, syndromic craniosynostosis, and postpharyngeal flap surgery. All patients included in the study demonstrated clinical signs of obstructive sleep apnea, such as snoring and cessation of breathing during sleep. An apnomonitor was used for presurgical and postsurgical sleep apnea status by measuring: 1) position during sleep; 2) percutaneous oxygen saturation; 3) respiratory analysis, such as the type of apnea-hypopnea, frequency of the events, and duration of apnea-hypopnea; 4) heart rate; and 5) snore analysis, such as trains, time, mean, and minimal and maximal amplifications. The apnea-hypopnea index (AHI) was significantly improved after surgery, especially in cases other than palatoplasty (7.4 +/- 8.73/h and 1.6 +/- 0.43/h, before and after surgery, respectively; P < 0.05 excluding palatoplasty). The percentage of snoring to total sleep was also improved significantly (22.4 +/- 19.74% and 9.0 +/- 8.54%, before and after surgery, respectively; P < 0.01 in all patients). Therefore, changes in sleep apnea parameters were elucidated in craniofacial surgery. Palatoplasty did not necessarily worsen the sleep apnea status, although there were snoring and anatomic abnormalities. Detachment of the pharyngeal flaps improved sleep apnea, and bimaxillary advancement was effective in normalizing sleep apnea.
