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 rest postures and tongue thrusting may be the result of hypertrophy of the lymphatic tissues in the upper airway. Orthodontists are aware of the deleterious effects these habits have on the developing face and dentition...

INTRODUCTION: Polysomnographic recordings of children with an apparent life-threatening event (ALTE) have often displayed signs of partial or complete obstruction during sleep. Various studies have focused on facial dysmorphia in infants with ALTE and tried to establish a correlation between ALTE and obstructive sleep apnoea. Our study evaluates the phenotypic characteristics and the presence of sleep disorders in pre-school children who had at least one ALTE in the first year of life...

Failure to manage function-related problems can lead to failures in the conduct of orthodontic treatment and to poor stability. However, even if the dysfunctions have been diagnosed by the practitioner, he/she will still be dependent on the quality of the rehabilitation. Traditionally, rehabilitation requires intensive participation on the part of patients in order to ensure stimulation to their cortical neural networks. Eric Kandel, winner of the Nobel Prize for Medicine in 2000, has shown that this approach stimulates information transmission by boosting the activity of the neurotransmittors...

Auriculo-Condylar Syndrome (ACS) is a craniofacial malformation syndrome characterized by external ear anomalies, hypoplasia of the mandibular condyle, temporomandibular joint abnormalities, micrognathia, and microstomia. Glossoptosis, masticatory abnormalities, orthodontic problems, and malocclusion occur in a majority of affected subjects. The clinical diagnosis is usually suggested by the pathognomonic ear appearance ("question mark ear"), consisting of a variable degree of clefting between the helix and earlobe...

OBJECTIVES: The purpose of this work was to evaluate the prevalence of snoring and its correlation with cranial and upper airway morphology in young individuals with orthodontic treatment need. PATIENTS AND METHODS: Parents of 379 children were consecutively interviewed, using eight questions from a more comprehensive questionnaire about sleep behavior. A total of 100 patients (54 girls, 46 boys, average age 11.3 years) met the inclusion criteria. Based on the parents' interviews, the sample was divided into snorers (n = 53) and nonsnorers (n = 47)...

Hyperventilation can be a manifestation of anxiety that involves abnormally fast breathing (tachypnea) and an elevated minute ventilation that exceeds metabolic demand. This report describes a case of hyperventilation-induced hypocapnia resulting in tetany in a 16-year-old girl undergoing orthodontic extractions under intravenous conscious sedation. Pulse oximetry is the gold standard respiratory-related index in conscious sedation. Although the parameter has great utility in determining oxygen desaturation, it provides no additional information on respiratory function, including, for example, respiratory rate...

INTRODUCTION: Abnormal breathing can be caused by developmental malformations or anatomical variations in the upper airways. Stomatognathic diseases may significantly impair the patency of the upper respiratory tract. Treatment of advanced stomatognathic dysfunctions is difficult due to their multifactorial aetiology, and often involves many phases. Sleep apnoea is one of the most bothersome complications. The mainstay therapeutic strategy relies on modifying the position of the mandible against the maxilla, achieved by using different types of oral appliances...

High school athletes seem particularly predisposed to dental injury, but athletic mouthguards have an excellent track record of success in reducing the severity and incidence of dental injuries in sports. Therefore, it has been suggested that mouthguards be made mandatory for high school athletes who participate in sports with risk of injury. The National Federation of State High School Associations currently recommends that mouthguards be mandated for high school football, lacrosse, ice hockey, and field hockey players as well as for wrestlers who are wearing orthodontic appliances...

AIM: Mouth breathing is a functional disorder that affects craniofacial and dento-alveolar growth and also upper airway (UA) anatomy. This is apparent mainly in dimensional abnormalities of the UA caused by hypertrophy of Waldeyer's ring and excessive vertical development of the lower part, giving rise to labial incompetence that perpetuates the functional disorder. The main aim of this study was to evaluate the development of the oropharyngeal structures in young hyperdivergent patients who had undergone functional genioplasty in the context of orthodontic treatment...

Rapid maxillary expansion (RME) is a widely used practice in orthodontics. Scientific evidence shows that RME can be helpful in modifying the breathing pattern in mouth-breathing patients. In order to promote the restoration of physiological breathing we have developed a rehabilitation program associated with RME in children. The aim of the study was a literature review and a model of orofacial rehabilitation in children with obstructive sleep apnea undergoing treatment with rapid maxillary expansion. Muscular training (local exercises and general ones) is the key factor of the program...

Obstructive sleep apnea syndrome (OSAS) is the most common sleep disordered breathing disorder (SDB) in adults and is characterized by a recurrent partial or complete collapse of the upper airway during sleep. This can be caused by many factors, sometimes interacting, such as skeletal malformations, soft tissue crowding, respiratory instability and the various effects of aging, obesity and gender that dictate craniofacial and upper airway anatomy. Research has demonstrated that the majority of patients exhibit at least one anatomical component such as retrognathia or a narrow posterior airway space that predisposes to the development of OSAS...

Rapid maxillary expansion (RME) is an effective orthopedic procedure that can be used to address problems concerned with the growth of the midface. This procedure also may produce positive side effects on the general health of the patient. The aim of the present consensus paper was to identify and evaluate studies on the changes in airway dimensions and muscular function produced by RME in growing patients. A total of 331 references were retrieved from a database search (PubMed). The widening of the nasal cavity base after midpalatal suture opening in growing patients allows the reduction in nasal airway resistance with an improvement of the respiratory pattern...
