One of the causes of nasal airway obstruction during inspiration is an incompetent nasal valve. An incompetent valve is one that collapses during quiet normal breathing due to narrowing of the valve area, a loss of upper and/or lower lateral cartilage support, or a combination of these. The most common etiology is a previous rhinoplasty; trauma and aging are other causes. Treatment is surgical and consists of replacing what is missing with similar tissue. If only the vestibular skin is scarred, a skin graft is used. If cartilage alone is missing, a cartilage graft is inserted. If both skin and cartilage are absent, a composite graft from the concha is the best choice.

Summary/introduction: Velopharyngeal incompetence(VPI) is the failure of closure of the velopharyngeal sphincter, which consists of the muscles of the soft palate and the superior pharyngeal constrictor, and functions to separate the nasopharynx and oropharynx during phonation and swallowing. VPI is most frequently congenital/syndromic (with structural deficit) but can be acquired. A subset of acquired VPI, occurring in structurally intact velopharynx, has been described in children, and these are isolated and acute-onset, with a substantial proportion thought to have an infectious origin.

Unlabelled: Defects such as cleft palate often co-occur with velopharyngeal (VP) incompetence, leading to dysfunction and a characteristic nasal snort in patients. With the evolution of treatment concepts, treatment of cleft palate patients has been introduced where obturators have helped improve the speech of individuals with partial or total velar defects, that is, cleft of the soft palate. The soft palate separates the oral and nasal cavities.

Objective: To assess the association between self-reported symptoms of pediatric OSA and clinical signs in MB children.
Methods: Seventy-three MB children aged 7-14 years answered an interview questionnaire on OSA symptoms in childhood, focusing on chewing, nasal, and sleep disturbances. MB children were checked for changes on the craniofacial, occlusion, TMJ, upper airway, and body posture by a multi-disciplinary team, consisting of medical residents, dental, and psychology postgraduate students.
