In this study, we present the surgical treatment of obstructive sleep apnea in a child with Treacher Collins syndrome. A 10-year-old girl with a past history of Treacher Collins syndrome presented to our clinic with her parents for respiratory distress and insomnia. The patient was referred to a sleep laboratory where she was diagnosed with obstructive sleep apnea, which was a consequence of her Treacher Collins syndrome. The patient underwent mandibular distraction osteogenesis under general anesthesia. The mandible was expanded by 15 mm using internal bilateral distractors. After distraction osteogenesis, the patient's respiratory problems resolved, and she was able to sleep comfortably. Distraction osteogenesis was an effective method of advancing the mandible, increasing the upper airway space and ultimately preventing obstructive sleep apnea syndrome in patients with Treacher Collins syndrome.

Objectives: This case report intended to examine how herbal medicine treatment for breathingrelated sleep disorders applied with polysomnography affected the structure of sleep. Methods: From January to November 2019, we retrospectively reviewed the progress records and polysomnography reports of patients who visited Korean medical hospitals in Daejeon and Cheonan. Results: In case 1, the patient complained of daytime sleepiness and snoring and was diagnosed with obstructive sleep apnea disorder and treated with Ukgan-san-gami. There were significant changes in the polysomnographic parameters, such as sleep efficiency, waking after sleep onset, sleep latency, the total arousal index, and the apnea-hypopnea index after herbal treatment. In case 2, the patient complained of frequent waking after sleep onset, daytime sleepiness, and snoring, and was diagnosed with obstructive sleep apnea disorder and treated with Yeoldahanso-tang-gami. There were significant changes in the polysomnographic parameters, such as the total arousal index and the apnea-hypopnea index after herbal treatment. In case 3, the patient complained of daytime sleepiness and was diagnosed with obstructive sleep apnea disorder and treated with Bangpungtongsung-san. There was no significant change in the polysomnographic parameters after herbal treatment. Conclusions: It is meaningful to note that objectively identifying the outcome of treatment for breathing-related sleep disorders is necessary in the clinical practice of Korean medicine.

Obstructive sleep apnea syndrome(OSAS) is a complex sleep disorder characterized by intermittent apnea secondary to sleep-induced obstruction of the upper airway. It occurs because of an airway obstruction anywhere between the trachea and the oronasal apparatus. The hallmark of OSAS is snoring, which is caused by vibration of the tissues of the pharynx as the airway narrows. The consequences of OSAS have focused on excessive daytime sleepiness resulting from sleep fragmentation and the cardiovascular derangements producing hypertension and arrhythmias. The primary method of controlling OSAS has been surgery. The current surgical procedures used for OSAS are tracheostomy, tonsillectomy, nasal septoplasty, uvulopalatopharyngoplasty, anterior mandibular osteotomy with hyoid myotomy and suspension, and maxillary, mandibular and hyoid advancement. We report a case of OSAS that was improved by genial advancement with infrahyoid myotomy and suspension. The patient was objectively documented by polysomnography, cephalometric analysis, and physical examination before the surgical procedure. The patient underwent genial advancement with infrahyoid myotomy and suspension. Patient had a good response from surgery.

Obstructive sleep apnea syndrome (OSAS) is characterized by obstructive events of the upper airway (UAW) during sleep, which can be associated with clinical signs and symptoms such as snoring, excessive daytime sleepiness, impaired memory, and fatigue. It is associated with many problems like psychosocial problems, physiologic alterations in the cardiovascular and respiratory systems as a result of hypoxia and repeated awakenings during sleep. Conservative treatments such as weight loss, sleep positioning, improvement of sleep hygiene, CPAP and MAD can be performed for the obstructive sleep apnea. However, their effect for the OSA is limited and differs by patient's individual properties. Accordingly, surgical reconstructions of the upper airway must be carried out for the treatment of OSA.

Sleep apnea is a disease that causes various complications, and the polysomnography is expensive and difficult to measure. The purpose of this study is to develop an unrestricted wearable monitoring system so that patients can be examined in a familiar environment. We used a method to detect sleep apnea events and to determine sleep satisfaction by non-constrained method using SpO2 measurement sensor and 3-axis acceleration sensor. Heart rate and SpO2 were measured at the finger using max30100. After acquiring the SpO2 data of the user in real time, the apnea measurement algorithm was used to transmit the number of apnea events of the user to the mobile phone using Bluetooth (HC-06) on the wrist. Using the three-axis acceleration sensor (mpu6050) attached to the upper body, the number of times of tossing and turning during sleep was measured. Based on this data, this algorithm evaluates the patient's tossing and turning during sleep and transmits the data to the mobile phone via Bluetooth. The power source used 9 volts battery to operate Arduino UNO and sensors for portability and stability, and the data received from each sensor can be used to check the various degree between sleep apnea and sleep tossing and turning on the mobile phone. Through thisstudy, we have developed a wearable sleep apnea measurement system that can be easily used at home for the problem of low sleep efficiency of sleep apnea patients.

The purpose of this study was to examine the anatomic changes in the upper airway with a dental orthosis. the effectiveness and side effects of orthosis in the treatment of snoring and obstructive sleep apnea. To meet this puppose a dental orthosis, designed to increase the size of the upper airway by advancing the mandible, was used in 42 patients (30 M, 12 F), aged 29 - 69 years, to treat snoring and varying decrees of obstructive sleep apnea. Cephalometric study of anatomic featured was made with and without a dental orthosis, and the evaluation of the effectiveness and side effects of orthosis was done by questionnaires. The obtained results were as follows : 1. All subjects were habitual snorers and 32 patients comp1ained the loudness of snoring as severe as be heard outside of the patient's room. 2. According to the degree of respiratory distirbance index(RDI) and aprea index(Al) from the polysomnograph in 34 patient, mild obstructive sleep apnea patients were 5, moderate 6 and severe 16. 3. Various anatomic changes in the upper airway with denta1 orthosis were as follows : (1) More superioly positioned hyoid bone ( p<0.001) (2) Enlarged oropharyngeal (superior p<0.01, middle p<0.01. inferior p<0.01) and hypopharyngeal (P<0.05) airway space. 4. According to the results of the changes of clinical syptoms after the usage of the dental orthosis acquired from questionnaires, there was significant improvement in the frequently, the loudness and the severity of snoring, cessation of breathing and awakening from the difficulty of breathing during sleep. 5. The effectiveness and side effects of dental orthosis by questionnaires were as follows ; (1) Dental orthosis satisfied almost all the patients (68±20%). (2) Snoring was improved in all the patients (73±19%). (3) Obstructive sleep aphea was improved in all the patients (61 ± 37%) (4) Sleepiness in the daytime was significantly improved (61 ±37%). (5) The sleep quality was significantly improved (61±37%). (6) The discomfort of the dental orthosis was minor (33±18%) and no serious complications were observed. 6. The dental orthosis is an effective treatment for the symptom of snoring, and it can also effectively treat varying degrees of obstructive sleep apnea.

페쇄성 수면무호흡증후군은 다양한 원인에 의하여 발생할 수 있으며, 특히 편도 및 아데노이드 비대증은 소아에서 가장 흔한 원인이다. 편도 및 아데노이드 비대증에 의하여 발생한 폐쇄성 수면무호흡증후군은 다양한 증상과 함께 행동 장애, 야뇨증, 성장 및 발달장애, 폐성심, 고혈압과 같은 다양한 합병증을 초래할 수 있다. 이러한 이유로 임상적으로 소아에서 폐쇄성 무호흡증상이 수면 중에 관찰되면 적절한 진단과정 후에 상태에 따라서 적극적인 치료가 필요하다. 소아에서의 치료는 편도 및 아데노이드 비대증에 의한 경우 수술적인 제거를 통하여 80% 이상에서 호전을 관찰할 수 있다. 그러나 편도 및 아데노이드 제거 후에도 증상이 남아있거나 수술적인 치료가 불가능한 환아에 대해서는 체중조절, 수면자세의 변화와 같은 생활습관의 조절 및 지속적 기도양압호흡기를 이용하여 추가적인 치료를 시행할 수 있다. 저자들은 수면다원검사상 심한 폐쇄성 수면무호흡이 관찰되어 편도 및 아데노이드 절제술을 시행한 후 증상의 호전이 있었으나, 장기간 추적관찰 후 재발한 수면무호흡과 코골이를 조절하기 위하여 생활습관의 개선교육과 자동화 기도양압호흡기로 치료한 1례를 경험하였기에 보고한다.

일반적으로 폐쇄성 수면 무호흡이 중추성 수면 무호흡보다 발생 비율이 높지만 심부전 환자에서는 체인-스토크스 호흡이 동반된 중추성 수면 무호흡이 흔하며, 실제로 심부전 환자에서 25~40%까지 중추성 수면 무호흡이 발생한다고 한다. 저자들은 호흡곤란으로 내원하여 심부전으로 진단된 환자가 관상동맥 중재술을 시행하고 난 이후 추적 시행한 심초음파 결과에 비해 주관적인 호흡곤란이 해결되지 않은 경우, 의료진의 자세한 병력 청취를 통해 환자가 평소 코골이와 수면 무호흡이 심하다는 소견을 바탕으로 조기에 수면 다원검사를 시행했다. 환자는 체인-스토크스 호흡을 동반한 중추성 수면 무호흡으로 진단 되어 지속적 상기도 양압술을 적용 후 호흡곤란 및 주간 졸림증이 호전 되었다. 심부전 환자에서 중추성 수면 무호흡이 동반된 경우, 피로감, 주간 졸림증 등과 같은 수면 무호흡의 일반적인 증상이 심부전 자체로 인한 증상으로 오인되어 중추성 수면 무호흡의 진단이 늦어 질 수 있으며, 이 경우 환자의 예후에 나쁜 영향을 끼칠 수 있다. 본 증례의 경우와 같이 심부전 환자의 치료 시 수면 무호흡을 의심할 만한 증상이 있는 경우 중추성 수면 무호흡의 동반 가능성을 염두해 두고 수면다원검사를 통해 중추성 수면 무호흡을 조기에 진단하는 것이 증상 호전 및 예후에 긍정적인 영향을 끼치는 것을 경험하였기에 보고하는 바이다.

Obstructive sleep apnea is a common disorder in which respiratory flow decreases or disappears despite respiratory effort due to occlusion of the upper respiratory tract during sleep. Oxidative stress and systemic inflammatory reaction induced by the obstruction cause complications such as hypertension, coronary artery disease, and diabetes and increase cancer incidence. Furthermore, in patients with interstitial lung disease, obstructive sleep apnea has a very high prevalence and is thought to have a close pathophysiological and clinical correlation. In other words, obstructive sleep apnea could be the cause or a complication of interstitial lung disease ; when these two afflictions coexist, the prognosis of the patient is worse. In patients with interstitial lung disease with obstructive sleep apnea, CPAP treatment significantly improved sleep and quality of life, as well as improved morbidity and mortality in a recent study. Therefore, early diagnosis and treatment of obstructive sleep apnea in patients with interstitial lung disease are very important, and additional studies designed to include patients with idiopathic pulmonary fibrosis as well as patients with advanced interstitial lung disease should be performed.
