RESUMO
INTRODUCTION AND OBJECTIVES: Obstructive sleep apnea (OSA) is a prevalent condition among electable to bariatric surgery obese patients, often remaining underdiagnosed, thereby increasing surgical risk. The main purpose was to determine prevalence of OSA among candidates for bariatric surgery and to assess the rate of underdiagnosis of this condition. Additionally, the study aimed to evaluate the specific performance of three sleep questionnaires and scales (Excessive Daytime Sleepiness Scale (EDSS), Epworth Sleepiness Scale (ESS), and STOP-Bang) in these patients. METHODS: A longitudinal, prospective, single-cohort study, with consecutive sampling including patients aged 18-65 years with obesity grade II (body mass index (BMI) ≥ 35â¯kg/m2) and hypertension, type 2 diabetes, metabolic syndrome or OSA or obesity grade III or IV (BMIâ¯≥â¯40â¯kg/m2) elective for bariatric surgery. Patients were evaluated at the Otorhinolaryngology department with an anamnesis regarding OSA including the administration of three sleep questionnaires (EDSS, ESS, and STOP-Bang), followed by cardiorespiratory polygraphy (CRP) for sleep evaluation. RESULTS: 124 patients were included in this study. While 74.2% of the sample exhibited OSA on CRP, only 28.2% had a prior diagnosis. The STOP-Bang questionnaire demonstrated the highest sensitivity (93.3%) for detecting moderate to severe OSA, although with low specificity (33.8%). EDSS and ESS did not show a significant association with the presence of OSA. CONCLUSIONS: OSA screening is crucial in candidates for bariatric surgery due to its high prevalence and low diagnosis rate. The STOP-Bang questionnaire may serve as a useful tool for identifying patients at risk of moderate to severe OSA and optimizing sleep assessments. However, further research is necessary to validate its utility in this specific population.
RESUMO
PURPOSE: This study aimed to obtain a comprehensive view of the risk of developing cancer in patients with obstructive sleep apnea (OSA) and to compare this risk between patients receiving continuous positive airway pressure (CPAP) therapy versus upper airway surgery (UAS). METHODS: We used both local data and a global-scale federated data research network, TriNetX, to access electronic medical records, including those of patients diagnosed with OSA from health-care organizations (HCOs) worldwide. We used propensity score matching and the score-matched analyses of data for 5 years of follow-up, RESULTS: We found that patients who had undergone UAS had a similar risk of developing cancer than those who used CPAP [hazard ratio of 0.767 (95% CI 0.559-1.053; P = 0.100)]. CONCLUSION: Analysis of the large data sets collected from HCOs in Europe and globally lead us to conclude that in patients with OSA, neither CPAP nor UAS were associated with the development of cancer better than in non-treated patients.

INTRODUCTION: Obstructive sleep apnea (OSA) is a common disorder with major neurocognitive and cardiovascular sequelae. The treatment of symptomatic patients with mild OSA remains controversial given that adherence to positive airway pressure (PAP) has historically been suboptimal. With this notion in mind, we assessed a daily transoral neuromuscular electrical stimulation (NMES) device for individuals with mild OSA. METHODS: The sample represents a subset of participants with a baseline AHI 5-14.9 events/hour, drawn from a parent study which also included participants with primary snoring. Outcome measures for the current study included changes in apnea-hypopnea index (AHI), Epworth Sleepiness Scale (ESS), Pittsburgh Sleep Quality Index (PSQI) and snoring levels before and after use of the NMES. RESULTS: Among 65 participants (68% men) with median age of 49 years (range 24 to 79) and median BMI of 27.7 kg/m2 (range 20 to 34), the NMES device was used daily for 6 weeks. We observed a significant improvement in the AHI from 10.2 to 6.8 events/hour among all participants and from 10.4 to 5.0 events/h among responders. Statistically significant improvements in the ESS, PSQI, objectively measured snoring, and bed partner-reported snoring were observed. Adherence among all participants was 85%. DISCUSSION: This NMES device has the benefit of being a treatment modality of daytime therapy which confers a high level of tolerability and patient acceptance. It alleviates the need for an in situ device during sleep and leads to improvements in OSA severity, snoring, and subjective sleep metrics, potentially crucial in mild OSA. Further studies are needed to define which individuals may benefit most from the device across the wider spectrum of OSA severity and assess long-term therapeutic outcomes.

Abstract Objectives: Hypertrophic palatine tonsils play a role in the blockage of the upper airway, one of the known causes of Obstructive Sleep Apnea (OSA). Therefore, it is possible that there is an association between tonsil size and the success of pharyngeal surgery during OSA treatment. The main objective of this study was to evaluate the relationship between tonsil grade and volume, as well as to establish whether a relationship exists between tonsil size and the success rate of pharyngeal surgery (tonsillectomy and pharyngoplasty with barbed sutures). Methods: This retrospective study includes forty-four adult patients who underwent tonsillectomy and pharyngeal surgery with barbed sutures for the treatment of simple snoring and OSA between January 2016 and September 2019. Patients who had been previously tonsillectomized or those for whom tonsil volume measurement was lacking were excluded. All patients underwent a pre-operative physical exploration at the clinic exam room and a sleep study. Prior to surgery a Drug Induced Sleep Endoscopy (DISE) was performed. Tonsil volume was measured intraoperatively using the water displacement method. The same sleep study was repeated six months following surgery. Results: A significant correlation was found between tonsil grade and volume and between such measurements and the blockage observed at the level of the oropharynx during the DISE. Moreover, an association was observed between tonsil volume, but not tonsil grade, and the success of tonsillectomy and pharyngoplasty with barbed sutures. A tonsil volume greater than 6.5 cm3 was linked to success during pharyngeal surgery. Conclusion: A correlation exists between tonsil grade and tonsil volume. A bigger tonsil volume is associated with a greater success rate of oropharyngeal surgery during treatment of OSA. Level of evidence: Level 3, non-randomized cohort study.
RESUMO
OBJECTIVE: Tongue base and hypopharynx are the major sites of obstruction in OSA patients with failed palatal surgery. In recent years, several minimally invasive procedures have been developed to address tongue base obstruction. However, the research focus has consistently been on the effectiveness of surgery in reducing obstructive sleep apnoea rather than on postoperative complications. In this systematic review and metanalysis we aim to review the complication rate of minimally invasive base of tongue procedures for OSAS in adults. DATA SOURCES: PubMed (Medline), the Cochrane Library, EMBASE, Scopus, SciELO and Trip Database. REVIEW METHODS: Data sources were checked by three authors of the YO-IFOS sleep apnoea study group. Three authors extracted the data. Main outcome was expressed as the complication rate and 95% confidence interval for each surgical technique. RESULTS: 20 studies (542 patients) met the inclusion criteria. The mean complication rate is 12.79%; 4.65% for minor complications, 6.42% if they are moderate, and 1.77% if severe. The most reported complication overall is infection, in 1.95% of cases, followed by transient swallowing disorder, occurring in 1.30% of the total sample. CONCLUSION: The heterogeneity amongst the included studies prevents us from obtaining solid conclusions. The available evidence suggests that minimally invasive base of tongue procedures may present a wide spectrum of complication rates, ranging from 4.4% in tongue base radiofrequency to up to 42.42% in tongue base ablation.

PURPOSE: The aim of our retrospective study is evaluating the effectiveness of barbed repositioning pharyngoplasty (BRP) in a consecutive cohort of patients and assessing its impact on positional indexes in order to potentially identify specific obstructive sleep apnea (OSA) phenotypes for patients who might benefit more significantly from this intervention. METHODS: A single-center retrospective study with baseline and follow-up type III sleep tests evaluating the Apnea Hypopnea Index (AHI), supine AHI, non-supine AHI, oxygen desaturation index (ODI), mean SaO2, percentage of time spent at SaO2 below 90% (CT90), and lowest oxygen saturation (LOS) were performed. The patients were then divided into groups according to Sher's criteria and Amsterdam Positional OSA Classification (APOC). Parametric and non-parametric tests and univariate and multivariate analyses were conducted. RESULTS: The study finally included 47 patients. The statistical analysis showed significant improvement in AHI, supine AHI, non-supine AHI, and ODI after surgery. The linear regression showed that high values of baseline AHI, AHI supine, and AHI non supine predict more significant postoperative reductions in AHI, AHI supine, and AHI non supine, respectively. Therapeutic success was achieved in 22 patients out of 47. The logistic regression did not find any independent risk factors for success. The most significant reduction in AHI, supine AHI, and non-supine AHI was observed in the APOC 3 group while the APOC 1 patients experience a substantially lower improvement. CONCLUSIONS: BRP appears to be an effective surgical procedure for the treatment of OSA. The non-positional patients might benefit more from BRP in comparison with positional patients. Moreover, OSA severity should not be considered an absolute contra-indication for this surgical procedure.
RESUMO
Background: A study is made of dental caries in a group of adults with sleep apnea-hypopnea syndrome (SAHS), establishing comparisons with healthy individuals corresponding to the same population. Material and Methods: A case-control series was analyzed, including patients with recently diagnosed SAHS and individuals without SAHS. Dental examinations were made to record the DMF (decayed, missing, filled) dental score, and demographic, lifestyle and clinical data were collected. Results: A total of 114 participants (60 SAHS cases and 54 controls) were included in the study. Although the mean DMF score in the SAHS group was higher than in the control group (7.03 versus 4.81, respectively), the multivariate regression analysis did not find the difference to be statistically significant (p=0.351). However, a significant correlation was observed between the DMF score and age (r=0.41; p<0.001) and the apnea-hypopnea index (AHI)(r=0.31; p=0.003). Conclusions: Older age and greater severity of SAHS are associated to higher DMF scores. However, the diagnosis of SAHS alone does not influence dental caries status. Key words:Dental caries, sleep apnea syndrome, oral health, DMF index.
RESUMO
Mandibular advancement devices (MAD) are an effective alternative treatment to CPAP. Different maneuvers were performed during drug sleep-induced endoscopy (DISE) to mimic the effect of MAD. Using the Selector Avance Mandibular (SAM) device, we aimed to identify MAD candidates during DISE using a titratable, reproducible, and measurable maneuver. This DISE-SAM protocol may help to find the relationship between the severity of the respiratory disorder and the degree of response and determine the advancement required to improve the collapsibility of the upper airway. Explorations were performed in 161 patients (132 males; 29 females) with a mean age of 46.81 (SD = 11.42) years, BMI of 27.90 (SD = 4.19) kg/m2, and a mean AHI of 26.51 (SD = 21.23). The results showed no relationship between severity and MAD recommendation. Furthermore, there was a weak positive relationship between the advancement required to obtain a response and the disease severity. Using the DISE-SAM protocol, the response and the range of mandibular protrusion were assessed, avoiding the interexaminer bias of the jaw thrust maneuver. We suggest prescribing MAD as a single, alternative, or multiple treatment approaches following the SAM recommendations in a personalized design.

OBJECTIVE: Nasal diseases are among the main motives for the early discontinuation of continuous positive airway pressure therapy and for long-term therapeutic compliance with mandibular advancement device. Although our clinical experience leads us to the belief that recumbency impacts nasal airflow in some patient populations, there is no consensus regarding the magnitude of this effect and the specific group of patients who are the most affected by this condition. In this study, we conducted a meta-analysis to assess the effect of the recumbent position on nasal resistance and nasal airflow. REVIEW METHODS: PubMed (Medline), Cochrane Library, EMBASE, Scopus, and SciELO databases were checked for relevant studies by two members of the YO-IFOS study group. The two authors extracted the data. The main outcome was expressed as the difference between nasal resistance and nasal airflow before and after recumbency. RESULTS: Nine studies with a total population of 291 individuals were included in the meta-analysis for nasal resistance after recumbency. We found a statistically significant difference in nasal airway resistance of -0.18 Pa sec/cm3 as compared to before and after recumbency through rhinomanometry (RMM) analysis. A subgroup analysis revealed a variation of -0.20 Pa sec/cm3 for patients with snoring or sleep apnea and - 0.10 Pa sec/cm3 for healthy individuals. Regarding nasal airflow measured with RMM, three studies (n = 32) in asymptomatic controls revealed a statistically significant difference of 47.33 ml/sec. CONCLUSIONS: Recumbency increases nasal resistance and diminishes nasal airflow. This finding is of utmost importance in snorers and sleep apnea patients. Laryngoscope, 132:6-16, 2022.

PURPOSE: Although upper airway surgery in selected patients with obstructive sleep apnea (OSA) has been shown to be beneficial, its long-term effects have been questioned. The main objective was to evaluate whether results following surgery remain stable over time, both in objective and subjective terms. As a secondary aim, such stability was also measured in relation with the type of surgery performed. METHODS: This work constitutes a retrospective study of OSA adult patients subjected to the following surgical procedures: different types of pharyngoplasties, tongue-base surgery, partial epiglottectomy or hyoid suspension. Those who exclusively underwent tonsillectomy or nasal surgery were excluded. Before surgery, a sleep study, and an assessment of the patients' sleepiness and quality of life were performed, which were repeated at 8, 34, and 48 months after surgery. A total of 153 patients was included. RESULTS: Following surgery, the apnea-hypopnea index decreased from 34.84/h to 14.54/h and did not vary more than one point in subsequent controls (p = 0.01). The oxygen desaturation index changed from 31.02/h to 14.0/h and remained stable in the second (15.34/h) and third (11.43/h) controls (p = 0.01). Parameters measuring sleepiness and well-being demonstrated the maintenance of long-term benefits. New pharyngoplasties were observed to be more stable than classic pharyngoplasties in the long term (p = 0.04). Single-level surgeries were found to be more stable than multilevel surgeries, although a statistically significant difference was not observed (p = 0.07). CONCLUSION: The benefits obtained remained stable in the long term. In our sample, modern pharyngoplasty techniques showed superiority over the classic ones regarding long-term stability.

RESUMEN Introducción: La cirugía del implante coclear es un método efectivo para la rehabilitación auditiva de los pacientes con hipoacusia neurosensorial severo-profunda, en los que el rendimiento con los audífonos no es suficiente. Aunque la implantación coclear es una técnica segura, es importante conocer sus posibles complicaciones, entre ellas la infección del colgajo o la parálisis facial. Objetivo: Analizar las complicaciones de los pacientes con implante coclear intervenidos en un hospital universitario terciario: El Hospital Universitario Doctor Peset de Valencia, desde enero de 2001 a marzo de 2020. Metodología: Estudio observacional descriptivo de las complicaciones en una muestra de 134 pacientes con implantación coclear en el Hospital Universitario Doctor Peset de Valencia, en un periodo de 20 años. En el análisis estadístico se utilizó estadística descriptiva. Para demostrar diferencias significativas entre variables empleamos el programa R. Se utilizó el test χ2 para proporciones, considerando significativo un valor p < 0.05. Resultados: 134 pacientes fueron implantados. La frecuencia global de complicaciones fue del 17.9%, 4.5% fueron complicaciones mayores y 13.4% fueron complicaciones menores. La complicación más frecuente fue la desactivación o inserción incompleta de algunos electrodos. Discusión: Las proporciones de complicaciones del estudio entran dentro de los rangos encontrados en la literatura (14.9-18.3%). La frecuencia de complicaciones mayores es inferior al 5%, proporción similar a la obtenida en nuestra serie. Conclusiones: El implante coclear es una técnica quirúrgica segura para la rehabilitación de pacientes con hipoacusia severa, aunque no está exenta de riesgo, por lo que se debe conocer sus potenciales complicaciones.

ABSTRACT Introduction: Cochlear implantation is an effective method for hearing rehabilitation in patients with severe neurosensory hearing loss in which hearing aids do not provide good discrimination. Although cochlear implantation is a safe technique, adverse effects related to surgery have been described, including flap infection or facial paralysis. Objective: To analyze the complications of cochlear implanted patients in a tertiary university hospital: The Hospital Universitario Doctor Peset of Valencia, from January 2001 to March 2020. Methodology: This is a descriptive observational study of the complications in a sample of 134 patients with cochlear implant surgery in The Hospital Universitario Doctor Peset of Valencia in a period of 20 years. Descriptive statistics were used in the statistical analysis. To demonstrate significant differences between variables we used the R program. The χ2 test was used for proportions, considering significant a p value < 0.05. Results: 134 patients were implanted. The global frequency of complications was 17.9%, 4.5% were major complications and 13.4% were minor complications. The most frequent complication was inactivation or incomplete insertion of some electrodes. Discussion: Our complication rate is within the range published in the literature (14.9-18.3%). The major complication rate is 5% which is similar to our series. Conclusions: The cochlear implant is a safe surgical technique for the rehabilitation of patients with severe neurosensory hearing loss, although it is not riskless, therefore, one must know that complication are possible.

Myofunctional therapy (MFT) may have a role in improving muscle tone and alleviating upper airway collapse in sleep-disordered breathing. The purposes of this state-of-the-art review are to first review systematically the current literature on the effectiveness of MFT in treating sleep-disordered breathing and then to provide an overview of the current understanding of patient selection, side effects, type and duration of exercises, guidance of exercise performance, evaluation of results, and how best to promote adherence. PubMed (Medline), the Cochrane Library, and the EMBASE, Scopus and SciELO databases were checked for relevant studies by three authors, and a total of 23 studies were included. This review focuses only on adults with sleep-disordered breathing. The available evidence shows a positive effect of MFT in reducing sleep apnoea, as measured using polysomnography and clinical variables (including snoring). There is no evidence of the utility of MFT for treating upper airway resistance syndrome, the duration of the effects of MFT, or regarding which MFT protocol is best. Despite these knowledge gaps, the available evidence suggests that MFT is a safe treatment modality.

PURPOSE: Screening for obstructive sleep apnea (OSA) is recommended in patients scheduled for bariatric surgery because continuous positive airway pressure (CPAP) therapy in patients with moderate-to-severe OSA reduces postoperative complications. However, cardiorespiratory polygraphy (CRP) and polysomnography (PSG) are expensive and time-consuming. The present study aimed to assess whether at-home continuous overnight pulse oximetry can be used to diagnose moderate-to-severe OSA in patients scheduled for bariatric surgery. METHODS: In this prospective observational study, we enrolled consecutive patients scheduled for bariatric surgery. Patients with no prior OSA diagnosis were evaluated using the ESS, SBQ, and preoperative at-home CRP. Correlations were calculated between AHI and oximetry parameters. For each oximetry parameter, a receiver-operating characteristic (ROC) curve was generated to identify optimal cut-off values for diagnosing moderate-to-severe OSA. RESULTS: In total, 117 patients were included. The oxygen desaturation index was the most correlated oximetry parameter; the optimal cut-off value for diagnosing moderate-to-severe OSA was 23.9. The sensitivity and specificity were 80 and 92%, respectively. The area under the ROC curve was 0.935. CONCLUSIONS: At-home continuous overnight pulse oximetry could be used to screen moderate-to-severe OSA in patients scheduled for bariatric surgery because it would allow clinicians to implement early CPAP therapy and avoid preoperative PSG or CRP.

OBJECTIVES: We aimed to explore the association between periodontitis and sleep apnea-hypopnea syndrome (SAHS) and the possible influence of body mass index (BMI) and obesity upon this association. MATERIALS AND METHODS: A case-control study was made involving 114 subjects (60 patients with SAHS and 54 controls). A thorough periodontal evaluation was carried out, and demographic and clinical data were collected. RESULTS: Periodontitis was more prevalent in SAHS (80%) than in the controls (48.1%). The recorded statistically significant association (OR = 4.31; p = 0.001) was seen to weaken in the multivariate model (OR = 2.03; p = 0.204), with BMI adopting a more influential role. The apnea-hypopnea index (AHI) was correlated to probing depth (PD) (r = 0.40; p = 0.002) and clinical attachment level (CAL) (r = 0.41; p = 0.001). The periodontal parameters were seen to be higher in obese SAHS patients (BMI ≥ 30 kg/m2) than in non-obese SAHS patients (BMI < 30 kg/m2). CONCLUSIONS: The greater prevalence and severity of periodontitis in patients with SAHS were fundamentally influenced by BMI. On the other hand, periodontitis was more severe in patients with severe SAHS. CLINICAL RELEVANCE: Patients with SAHS have a greater prevalence of periodontitis, fundamentally related to increased obesity. Therefore, obese subjects with SAHS should be screened for periodontal disease.

INTRODUCTION AND PURPOSES: The relevance of the lateral pharyngeal walls in the collapse of the upper airway in obstructive sleep apnea patients has been revealed in the last 20years. New surgical techniques that address this collapse have been published. The aim of this study is to show the technique that we are currently using to treat the collapse and its results. MATERIALS AND METHODS: This is a retrospective study of surgically treated OSAS patients who did not tolerate conventional positive airway pressure (CPAP) or for whom it was not indicated. After a complete physical examination either awake or under drug-induced sleep endoscopy, tonsillectomy with reposition pharyngoplasty was performed using barbed bidirectional suture and removing the supratonsillar fat. Three to 6months after surgery the subjective parameters were evaluated and a sleep study was performed. RESULTS: Twenty-six patients were enrolled with a significative decrease in the AHI and also significative improvement in all the rest parameters studied. In 65.4% of the patients the AHI decreased 50% and was lower than 20/h, in 42.3% postoperative AHI was lower than 10/h. The most frequent complication was the partial extrusion of the suture. CONCLUSIONS: This surgical procedure obtains statistically significant results in objective and subjective parameters of sleep apnoea without major associated complications.
RESUMO
OBJECTIVE: Does nasal surgery affect multilevel surgical success outcome. METHODS: Prospective eight country nonrandomized trial of 735 obstructive sleep apnea (OSA) patients, who had multilevel palate and/or tongue surgery, divided into two groups, with or without nose surgery. RESULTS: There were 575 patients in nose group, 160 patients in no nose group. The mean age for nose group 44.6 ± 11.4, no nose group 44.2 ± 11.8. Mean preoperative BMI for nose group 27.5 ± 3.6, no nose group 27.5 ± 4.1, mean postoperative BMI nose group 26.3 ± 3.7, no nose group 27.1 ± 3.8 (P = .006). Mean preoperative AHI nose group 32.7 ± 19.4, no nose group 34.3 ± 25.0 (P = .377); and mean postoperative AHI nose group 13.5 ± 10.2, no nose group 17.1 ± 16.0 (P = .001). Mean preoperative ESS nose group was 11.3 ± 4.7, no nose group was 10.4 ± 5.4 (P = .051); and mean postoperative ESS nose group was 5.3 ± 3.2, no nose group was 6.7 ± 2.8 (P = .001). The nose group had higher percentage change (adjusted for age, gender, BMI) in AHI (33.7%, 95% CI 14% to 53.5%) compared to the no nose group (P = .001); the nose group also had more percentage change in ESS (37%, 95% CI 23.6% to 50.3%) compared to the no nose group (P < .001). Change in BMI did not affect AHI nor ESS change (Cohen effect 0.03 and 0.14, respectively). AHI change in both groups were also statistically significant in the mild OSA (P = .008) and the severe OSA (P = .01). Success rate of surgery for the nose group 68.2%, while the no nose group 55.0% (P = .002). CONCLUSION: Combining nose surgery in multilevel surgery improves surgical success. LEVEL OF EVIDENCE: IIC.
RESUMO
BACKGROUND: To describe the characteristics of xerostomia (dry mouth) in the population with sleep apnea-hypopnea syndrome (SAHS) and contrast its prevalence versus that found in healthy subjects, and to compare the frequency of xerostomia in SAHS patients with and without continuous positive airway pressure (CPAP) treatment. MATERIAL AND METHODS: A prospective comparative study was made between adults recently diagnosed with SAHS in a public hospital (n=60) and healthy individuals (n=54). The presence of xerostomia was assessed on waking up and during the day, using a frequency scale from 0 ("never") to 3 ("always"). RESULTS: The prevalence of xerostomia on waking up in the SAHS group was 45%, versus 20.4% among the controls. During the rest of the day the prevalence of the symptom decreased in both the SAHS group (21.7%) and among the controls (9.3%). Multiple binary logistic regression analysis found body mass index (BMI) to be correlated to the association SAHS-xerostomia on waking up (p=0.007). Patients with moderate SAHS had a greater frequency of xerostomia than those with mild SAHS (p=0.022). The frequency of xerostomia on waking up was significantly greater in patients using CPAP than in those without such treatment (57.1% versus 16.7%, respectively) (p=0.008). CONCLUSIONS: The frequency of xerostomia was greater in patients with SAHS, particularly on waking up and in those receiving CPAP. The symptom was more prevalent in individuals with moderate to severe SAHS than in those with mild SAHS, and was significantly influenced by BMI. Key words:Sleep apnea, xerostomia, dry mouth, CPAP, side effects, body mass index, obesity.
