A short lingual frenulum has been associated with difficulties in sucking, swallowing and speech. The oral dysfunction induced by a short lingual frenulum can lead to oral-facial dysmorphosis, which decreases the size of upper airway support. Such progressive change increases the risk of upper airway collapsibility during sleep. Clinical investigation of the oral cavity was conducted as a part ...

The origins of Orofacial Myofunctional Therapy began in the early 1960's by orthodontists who recognized the importance of functional nasal breathing, proper swallowing, and more ideal oral rest postures. Re-patterning these functions through myofunctional therapy assisted with better orthodontic outcomes and improved stability. Experts in orofacial myology have concluded that improper oral res...

Abstract Introduction The ExVent is an optional accessory to the O2Vent Optima mandibular advancement device (MAD) and provides oral Expiratory Positive Airway Pressure (EPAP). Oral EPAP with designed provide upper airway support via similar mechanisms of action nasal devices in commercial distribution, e.g., passive dilatation airway, which reduces flow limitation. Nasal are distribution as st...

Background: Pharyngeal mucosal space abscess is a very rare deep neck infection. Due to the anatomical relationship with the pharyngeal airway, patient may have some signs and symptoms of upper airway obstruction. Decision in airway management is important to reduce morbidity and be able to drain the abscess. Objective: To report a potential devastating airway complication in a patient with pha...

Obstructive sleep apnea (OSA) is a disorder caused by number of factors like an obstruction the upper airway during because insufficient motor tone tongue and/or dilator muscles or inadequate growth maxillary jaw bone etc. Oral appliances (OAs) are commonly used as non-invasive treatment for obstructive syndrome. The primary oral appliance (OA) in mandibular advancement device (MAD). Tongue-ret...

OBSTRUCTIVE SLEEP APNEA (OSA) IS A HIGHLY PREVALENT SYNDROME THAT IS ASSOCIATED WITH SUBSTANTIAL MORBIDITY AND INCREASED MORTALITY.1-10 Positive airway pressure (PAP) is the most uniformly effective therapy, and to date this is the only intervention for OSA shown to have a favorable impact on both cardiovascular and neurobehavioral morbidities.1,2,6 However, approximately 25-50% of patients wit...

BACKGROUND Obstructive sleep apnea (OSA) is a common sleep disorder and is characterized by airway collapse at multiple levels of upper airway. The effectiveness of nasal surgery has been discussed in several studies and shows a promising growing interest. In this study, we intended to evaluate the effects of nasal surgery on the upper airway dimensions in patients with OSA using three-dimensio...

The upper airway is a vital part of the respiratory tract. Although the upper airway serves several functions, protection of the airway and preservation of airway patency are the most essential functions subserved by upper airway reflexes. Various types of nerve endings have been identified in and under the epithelium of the upper airway, and afferent nerve endings are the natural starting of a...

BACKGROUND The anatomical configurations of respiratory tract would be directly associated with their ventilatory function. It is necessary to fully understand the association between airway configurations and their functions as well as the interactions between different airway segments. In this study, we developed a respiratory airway model to investigate the effects of bronchial structural ab...
