Abstract Obstructive sleep apnea, is a common disorder that is characterized by repetitive partial or complete cessation of air flow, associated with oxy-hemoglobin desaturation and increased effort to breath. Treatment of obstructive sleep apnea can be divided into four general categories. These include: lifestyle modification, upper airway surgery, oral appliances, and continuous positive airway pressure (CPAP). Although the CPAP provides the most reliable therapeutic modality, it is the most cumbersomeone. Many patients, particularly young non-apneic snorers, find it unappealing, difficult to tolerate, and unacceptable. The only other non-invasive alternative, which can producefavourable results within a short time, is oral appliances. How to cite this article Manohar MR, Talesra J.

Osa Treatment

Obstructive sleep apnea (OSA) is a disorder caused by a number of factors like an obstruction of the upper airway during sleep because of insufficient motor tone of the tongue and/or airway dilator muscles or inadequate growth of the maxillary jaw bone etc. Oral appliances (OAs) are commonly used as a non-invasive treatment for obstructive sleep apnea syndrome. The primary oral appliance (OA) used in obstructive sleep apnea (OSA) treatment is the mandibular advancement device (MAD). Tongue-retaining devices or tongue-stabilizing devices (TSDs) are a second type of OA, which displace the tongue anteriorly and may be customized or come in different stock sizes. This review article aims to examine the best in class on this particular subject of treatment of OSA with oral appliances, explaining acceptability of an appliance in patients on the basis of its construction and results, while providing enough cognizance regarding the diagnosis, management and causes of discontinuation.

The Impact

<b><i>Objective:</i></b> The purpose of this study was to evaluate the effects of nasal surgery on airflow characteristics in patients with obstructive sleep apnea (OSA) by comparing the alterations of airflow characteristics within the nasal and palatopharyngeal cavities. <b><i>Methods:</i></b> Thirty patients with OSA and nasal obstruction who underwent nasal surgery were enrolled. A pre- and postoperative 3-dimensional model was constructed, and alterations of airflow characteristics were assessed using the method of computational fluid dynamics. The other subjective and objective clinical indices were also assessed. <b><i>Results:</i></b> By comparison with the preoperative value, all postoperative subjective symptoms statistically improved (<i>p</i> &#x3c; 0.05), while the Apnea-Hypopnea Index (AHI) changed little (<i>p</i> = 0.492); the postoperative airflow velocity and pressure in both nasal and palatopharyngeal cavities, nasal and palatopharyngeal pressure differences, and total upper airway resistance statistically decreased (all <i>p</i> &#x3c; 0.01). A significant difference was derived for correlation between the alteration of simulation metrics with subjective improvements (<i>p</i> &#x3c; 0.05), except with the AHI (<i>p</i> &#x3e; 0.05). <b><i>Conclusion:</i></b> Nasal surgery can decrease the total resistance of the upper airway and increase the nasal airflow volume and subjective sleep quality in patients with OSA and nasal obstruction. The altered airflow characteristics might contribute to the postoperative reduction of pharyngeal collapse in a subset of OSA patients.
