Therapeutic Outcome of Primary Snoring and Mild Obstructive Sleep Apnea and Clinical Suggestion for Treatment Approaches / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: The clinical significance and need for the treatment of primary snoring and mild obstructive sleep apnea have been recently questioned. In this study, we analyzed therapeutic outcome and the methods of treatment of such diseases. SUBJECTS AND METHOD: A retrospective review was conducted using the medical records of patients diagnosed with primary snoring or mild obstructive sleep apnea at a single institution from 2013 to 2015 through polysomnography or WATCHPAT. RESULTS: Of the 18 patients (37%) with primary snoring, 13 patients (72.2%) underwent surgery, four patients (22.2%) were treated with surgery and mandibular advancement device, and one patient (5.6%) underwent automatic positive airway pressure therapy. Of the 78 patients (61%) with mild obstructive sleep apnea, 35 patients (44.8%) had surgery, 24 patients (30.8%) were treated with mandibular advancement device, 13 patients (16.7%) were treated with surgery and mandibular advancement device and 6 patients (7.7%) received automatic positive airway pressure therapy. For primary snoring, while Epworth Sleepiness Scale and Pittsburg Sleep Quality Index did not improve, the snoring visual analog scale decreased significantly. In patients with mild obstructive sleep apnea, Apnea-Hypopnea Index, snoring decibel, Epworth Sleepiness Scale, and Pittsburg Sleep Quality Index were significantly decreased after treatment and the lowest oxygen saturation was significantly increased after treatment. CONCLUSION: For primary snoring, the direction of treatment should be determined in accordance with the presence of associated diseases related to sleep disturbance breathing. For mild obstructive sleep apnea, active treatment may be helpful.

Roncopatía primaria y sus implicancias clínicas: fin al paradigma de entidad inocua / Primary snoring and clinical implications: end the harmless entity paradigm

La Roncopatía Primaria constituye un trastorno respiratorio del sueño caracterizado por la ausencia de apneas, desaturaciones y microdespertares. Afecta a más del 50% de la población adulta, traduciendo una obstrucción parcial de la vía aérea superior. Hasta hace poco, fue considerada por el mundo médico como una manifestación benigna sin un trasfondo patológico significativo, sin embargo, hoy sabemos que constituye una entidad patológica en sí misma y determina importantes repercusiones nocivas a nivel de funciones neurocognitivas, metabólicas y cardiovasculares. Si bien la polisomnografía persiste considerándose el gold standard en su estudio, nuevas líneas tales como análisis acústicos del ronquido presentan una relevancia creciente. En un futuro próximo, el estudio etiológico y de los mecanismos histopatológicos y bioquímicos que determinan las repercusiones clínicas de la roncopatía, aportará nuevas herramientas que contribuirán al desarrollo de una hoy necesaria nueva concepción de los trastornos obstructivos del sueño.

The primary snoring is a respiratory disorder of the sleep characterized by the absence of apnea, desaturation and arousals. It affects more than 50% of the adult population, exposing a partial obstruction of the upper airway. Until recently, it was considered by the medical world as a benign manifestation without significant pathological background, however, we now know that it is a disease entity in itself and determines important deleterious impact at neurocognitive, metabolic and cardiovascular levels. Although polysomnography still remains being the gold standard in its study, new lines such as acoustic analysis of snoring have an increasing relevance. In the near future, the study of the etiological, histopathological and biochemical mechanisms that determine the clinical implications of snoring, will provide new tools that will contribute to the development of a new conception of obstructive sleeping disorders.

Discrimination between obstructive sleep apnea syndrome and primary snoring in children : comparison of clinical parameters and behavioral disturbance / 소아과

PURPOSE: To determine whether primary snoring could be distinguished from obstructive sleep apnea syndrome (OSAS) by clinical evaluation and symptom scores. METHODS: 56 snoring and 20 asymptomatic subjects were recruited and polysomnography was used to confirm that there were 39 OSAS, 17 primary snoring, and 20 control subjects. We evaluated the size of the childrens adenoids and tonsils. Parents completed sleep disordered breathing scale (SDBS) and obstructive sleep apnea 18 (OSA-18) questionnaires for use as symptom scores, as well as an attention deficit hyperactivity disorder rating scale-IV (ADHD RS-IV). RESULTS: There were no differences between primary snoring and OSAS in terms of tonsil and adenoid size, SDBS (9.4+/-4.6 vs 10.8+/-4.5), and OSA-18 score (61.1+/-25.1 vs 71.2+/-8.4). The patients with OSAS (15.8+/-7.9) and PS (22.2+/-9.4) had a higher ADHD RS-IV score than the control subjects (2.9+/-3.3). There was no difference in the ADHD RS-IV scores of patients with primary snoring and OSAS. CONCLUSION: We confirmed that clinical evaluation could not distinguish OSAS and primary snoring. In addition, our study suggests that primary snoring as well as OSAS is associated with attention deficit hyperactivity disorder.

Characteristics of Polysomngraphy on Children with Obstructive Sleep Apnea Hypopnea Syndrome and Primary Snoring / 实用儿科临床杂志

Objective To explore the polysomnography(PSG) characteristice of obstructive sleep apnea hypopnea syndrome(OS-AHS) and primary snoring(PS) in children and clinical value of PSG in children with sleep disorders. Methods We analyzed 74 children with OSAHS and 62 with PS, every patient being monitored with PSG for 7 hours at night for 16 parameters, including apnea hypopnea index(AHI), periodic leg movement index(PLMI),and the lowest oxygen saturation(LSaQ2) etc. The parameters of the 2 groups were comparaed. Results Comparaed with PS group, there was statistically significant difference in parameters such as PLMI, AHI,LSaQ2,the moderate oxygen saturation(MSaO2).AHI in non- rapid eye movement (NREM)(P
