Background Endoscopic skull base surgery continues to evolve in its indications, techniques, instrumentation, and postoperative care. As surgery of the skull base will often violate dura, intraoperative and postoperative cerebrospinal fluid (CSF) leak is not uncommon and represents a potential conduit for air and bacterial contamination. Patients with obstructive sleep apnea (OSA) requiring continuous positive airway pressure (CPAP) therapy undergoing skull base surgery represent a challenging group. However, there appears to be a paucity of consensus regarding the postoperative management of this patient population. The objective of this study is to examine practice patterns and expert opinion on the use of postoperative CPAP and nasal saline in patients with OSA. Methods A 14-item survey was generated by consensus among expert authors and distributed online to members of the North American Skull Base society and other international skull base community members. Data were analyzed for median, mean, and standard deviation variables. Subgroup analysis was completed between surgeons from different geographical locations and operative experience. SPSS22 was utilized for all complex statistical analysis and figures. Results Seventy-one responses were collected from skull base surgeons. In patients with OSA, respondents would resume patients’ CPAP therapy after a mean of 10.1 days (median, 7; standard deviation [SD], 10.2), without a CSF leak. In the presence of a small CSF leak, the mean duration would increase to 14.3 days (median, 14; SD, 9.8) and to 20.7 days (median, 21; SD, 11.8) in the presence of a larger leak. A surgeon’s choice to attribute the relationship between delaying the start of nasal saline and CPAP after the endoscopic skull base surgery with progressively more challenging skull base repair was found to be statistically significant ( P < .001). Conclusion Saline and CPAP therapies are initiated after the endoscopic skull base surgical repairs by surgeons at an increasing temporal delay in relation to the degree and complexity of the skull base defect repaired.

Background For patients with obstructive sleep apnea (OSA), there is a lack of knowledge regarding the impact of continuous positive airway pressure (CPAP) on the nasal cavity. There is a significant need for evidence-based recommendations regarding the appropriate use of CPAP following endoscopic sinus and skull base surgery. Objective The goal of this study is to translate a previously developed cadaveric model for evaluating CPAP pressures in the sinonasal cavity by showing safety in vivo and quantifying the effect of positive pressurized air flow on the nasal cavity of healthy individuals where physiologic effects are at play. Methods A previously validated cadaveric model using intracranial sensor catheters has proved to be a reliable technique for measuring sinonasal pressures. These sensors were placed in the nasal cavity of 18 healthy individuals. Pressure within the nose was recorded at increasing levels of CPAP. Results Overall, nasal cavity pressure was on average 85% of delivered CPAP. The amount of pressure delivered to the nasal cavity increased as the CPAP increased. The percentage of CPAP delivered was 77% for 5 cmH2O and increased to 89% at 20 cmH2O. There was a significant difference in mean intranasal pressures between all the levels of CPAP except 5 cmH2O and 8 cmH2O ( P < .001). Conclusion On average, only 85% of the pressure delivered by CPAP is transmitted to the nasal cavity. Higher CPAP pressures delivered a greater percentage of pressurized air to the nasal cavity floor. Our results are comparable to the cadaver model, which demonstrated similar pressure delivery even in the absence of anatomic factors such as lung compliance, nasal secretions, and edema. This study demonstrates the safety of using sensors in the human nasal cavity. This technology can also be utilized to evaluate the resiliency of various repair techniques for endoscopic skull base surgery with CPAP administration.

Long Term Follow Up

Studies have investigated the applications of Continuous Positive Airway Pressure (CPAP) therapy in the treatment of hypernasality due to velopharyngeal dysfunction (VPD; Cahill et al., 2004; Kuehn, 1991; Kuehn, Moon, & Folkins, 1993; Kuehn et al., 2002). The purpose of this study was to examine the effectiveness of CPAP therapy to reduce hypernasality in a female subject, post-traumatic brain injury (TBI) and pharyngeal flap, who presented with signs of VPD including persistent hypernasality. Improvements in mean velopharyngeal orifice size, subjective perception of hypernasality, and overall intelligibility were observed from the baseline to 8-week post-treatment assessment intervals. Additional long-term assessments completed at 2, 3, and 4 months post-treatment indicated decreases in immediate post-treatment improvements. Results from the present study suggest that CPAP is a safe, non-invasive, and relatively conservative treatment method for reduction of hypernasality in selected patients with TBI. More stringent long-term follow up may indicate the need for repeated CPAP treatment to maintain results.

Obstructive Sleep

Obstructive sleep apnea (OSA) is a common disease, with approximately 3–7% of men and 2–5% of women worldwide suffering from symptomatic OSA. If OSA is left untreated, hypoxia, microarousals and increased chemoreceptor stimulation can lead to complications like hypertension (HT). Continuous positive airway pressure (CPAP) is the most common treatment for OSA, and it works by generating airway patency, which will counteract the apnea or hypopnea. More than one billion people in the world suffer from HT, and the usual treatment is pharmacological with antihypertensive medication (AHM). The focus of this review will be to investigate whether the CPAP therapy for OSA affects HT.

Abstract Introduction Co-morbid insomnia and sleep apnoea (COMISA) is a prevalent and debilitating condition that is difficult to treat. COMISA patients have lower average adherence to continuous positive airway pressure (CPAP) therapy compared to patients with sleep apnoea alone. However, a sub-sample of COMISA patients may show adequate CPAP use that improves both the insomnia and sleep apnoea. It is important to identify this group of CPAP-responsive COMISA patients to guide personalised-medicine approaches. Methods Seventy-three COMISA patients (AHI≥15; ICSD-3 insomnia; 55% male, Age M=57y) completed questionnaires, home-based polysomnography, and one-week sleep diaries before and 6-months after commencing CPAP therapy. No patients accessed CBTi. We investigated baseline predictors of CPAP adherence (min/night) and overall change in Insomnia Severity Index (ISI) scores during treatment. Results Average CPAP adherence was 205 minutes/night (SD=153). 56% of patients used CPAP at least 4h/night. Average CPAP adherence was predicted by higher baseline AHI (r=0.39), arousal index (r=0.28), N1 sleep (r=0.32) and age (r=0.26), and lower N3 sleep (r=-0.28). The ISI decreased from baseline (17.9, CI=1.2) to 6-month follow-up (11.6, CI=1.3; p&lt;0.001). There was a significant positive association between ISI reduction and CPAP use (r=0.31). 26% of patients reported an ISI&lt;8 at 6-month follow-up. Conclusion Approximately half of COMISA patients show CPAP adherence of ≥4h/night and one quarter experience insomnia remission with CPAP. CPAP use is positively associated with AHI, light sleep, and age at baseline, and reduction of insomnia severity during treatment. Future randomized controlled trials are required to confirm the results of this small un-controlled study.

The need for speeding up the diagnosis and treatment of sleep-disordered breathing has increased in recent years. In order to achieve that, a split-night protocol has been implemented, in which the patient with suspected sleep-disordered breathing undergoes a diagnostic and therapeutic study in one night. Elshaug et al. (1), by using the split-night protocol, were able to reduce the time to initiate continuous positive airway pressure (CPAP) therapy by 15% in patients with severe obstructive sleep apnea. However, reviewing the limitations of said protocol is necessary to make it more streamline.

Abstract Introduction Obstructive sleep apnea (OSA) is one of the common causes of hypertension. Therefore, we examine the longitudinal effect of continuous positive airway pressure (CPAP) therapy and its adherence on blood pressure among OSA patients. Methods One thousand two hundred ninety-three (male 1,130, female 163) patients, who were diagnosed with OSA and underwent CPAP therapy were investigated for longitudinal changes (24 months observation period) in the levels of blood pressure and body weight. The longitudinal analyses were performed by mixed effect model. Multiple Imputation with Chained Equations was also used to impute missing data. Good CPAP adherence is defined as more than 70% of the time using CPAP more than 4hours at all the measuring. Poor CPAP adherence is defined as less than 70% of the time using CPAP more than 4hours at all the measuring time points. Results The patient group with good CPAP adherences), compared to poor CPAP adherence, showed significant diastolic blood pressure reduction in 24 months follow-up period (β=-0.13, p=0.03) despite a lack of significant weight loss (β=-0.02, p=0.59). However, no significant associations were found between systolic blood pressure and CPAP adherence (β=-0.14, p=0.11). Conclusion CPAP therapy was found to have a longitudinal effect on diastolic blood pressure despite a lack of significant weight loss. Support

Continuous positive airway pressure (CPAP) therapy is the gold standard treatment for obstructive sleep apnoea, which affects millions of people worldwide. However, this therapy normally results in symptoms such as dryness, sneezing, rhinorrhoea, post-nasal drip, nasal congestion and epistaxis in the upper airways.Using bronchial epithelial (Calu-3) and nasal epithelial (RPMI 2650) cells in an in vitro respiratory model, this study, for the first time, investigates the effect of CPAP positive pressure on the human respiratory epithelial mechanisms that regulate upper airways lubrication characteristics. To understand how the epithelium and mucus are affected by this therapy, several parameters were determined before and after positive pressure application.This work demonstrates that the positive pressure not only compresses the cells, but also reduces their permeability and mucus secretion rate, thus drying the airway surface liquid layer and altering the mucus/water ratio. It is also observed that the respiratory epithelia is equally inflamed without or with external humidification during CPAP application.These findings clearly identify the causes of the side-effects reported by patients under CPAP therapy.

AbstractStudy ObjectivesThe effect of continuous positive airway pressure (CPAP) on mediators of cardiovascular disease and depression in women with obstructive sleep apnea (OSA) is unknown. We aimed to assess the effect of CPAP therapy on a variety of biomarkers of inflammation, antioxidant activity, and depression in women with OSA.MethodsWe conducted a multicenter, randomized controlled trial in 247 women diagnosed with moderate-to-severe OSA (apnea–hypopnea index [AHI] ≥ 15). Women were randomized to CPAP (n = 120) or conservative treatment (n = 127) for 12 weeks. Changes in tumor necrosis factor α (TNFα), interleukin 6 (IL-6), C-reactive protein (CRP), intercellular adhesion molecule 1 (ICAM-1), catalase (CAT), superoxide dismutase (SOD), and brain-derived neurotrophic factor (BDNF) were assessed. Additional analyses were conducted in subgroups of clinical interest.ResultsWomen had a median (25th–75th percentiles) age of 58 (51–65) years, body mass index 33.5 (29.0–38.3) kg/m2, and AHI 33.3 (22.8–49.3). No differences were found between groups in the baseline levels of the biomarkers. After 12 weeks of follow-up, there were no changes between groups in any of the biomarkers assessed. These results did not change when the analyses were restricted to sleepy women or to those with severe OSA. In women with CPAP use at least 5 hours per night, only TNFα levels decreased compared to the control group (−0.29 ± 1.1 vs −0.06 ± 0.53, intergroup difference −0.23 [95% CI = −0.03 to −0.50]; p = 0.043).ConclusionsTwelve weeks of CPAP therapy does not improve biomarkers of inflammation, antioxidant activity, or depression compared to conservative treatment in women with moderate-to-severe OSA.Trial RegistrationNCT02047071.
