To address this gap, the NIH-funded ‘Craniofacial microsomia: Accelerating Research and...
Purpose
This article reviews the literature focused on the psychological effects of craniofacial care for patients and their families. It provides an overview of pediatric medical traumatic stress (PMTS) associated with craniofacial conditions and related care, along with a review of its risk and protective factors. Findings from studies of PMTS in...
Objective Individuals with cleft lip and palate (CLP) are at a high risk of developing obstructive sleep apnea (OSA). Hypothetically, the severity of OSA might be associated with the morphology of the upper airway (UAW) and the characteristics of the airflow. Thus, the present study aimed to assess and compare, in adults with CLP and skeletal class...
Objective:
Craniofacial microsomia (CFM) is a broad clinical term used to describe a congenital condition most commonly involving the underdevelopment of the external ear, mandible, soft tissues, and facial nerve.

Children with cleft palate and other craniofacial anomalies are at risk for a variety of otopathologies including otitis media and structural deformities of the outer and middle ear. These conditions are usually associated with conductive hearing impairment; however, when hearing loss occurs as part of a syndrome, there may be sensorineural or mixe...
Abstract An otolaryngology evaluation is an important aspect of care for any craniofacial patient. Otolaryngologists are commonly involved in the care of these patients to treat chronic otitis media, frequently requiring placement of pressure equalization tubes; however, there are many other otorhinolaryngologic issues that are addressed. Craniofac...

The choice of antibiotics for sinusitis in children with cystic fibrosis (CF) is empirical or based on lower airway cultures, because sinus cultures are difficult to obtain. The aim of this study was to identify the main organisms cultured from CF children with chronic sinusitis, and to evaluate the concordance of concomitant sinus, oropharyngeal s...
Obstruction of tympanostomy tubes is a potentially significant complication, sometimes requiring replacement of the nonfunctioning tube.

A choristoma is a tumor-like mass consisting of tissues that are foreign to the site at which they are located. A hamartoma, on the other hand, is a tumor-like mass consisting of tissues that are native to the site of origin. We report a choristoma in the nasopharynx that consisted of normal skin tissue.
The possible occurrence of developmental effects associated with mild hearing loss remains a significant concern. Recent psychoacoustic results in animals and humans suggest that mild conductive hearing loss can have negative consequences for binaural hearing in young listeners. These results appear to have physiological analogues in animal studies...

Congenital nasal pyriform aperture stenosis (CNPAS) is a recently defined clinical entity that causes airway obstruction in the neonate as a result of narrowing of the nasal pyriform aperture. The first description of nasal pyriform aperture stenosis (NPAS) was in 1952 by Douglas,1 who reported a series of eight affected adults, most of whom also h...
In infants and children, cervical masses originate from a variety of pathologic, congenital and developmental conditions, and it is important to distinguish benign from serious lesions. Fibromatosis colli is a rare cervical lesion that typically presents in the neonatal period. It is the most common cause of neonatal torticollis and should be recog...
Nitric oxide (NO) production in the respiratory epithelium of the upper airways has recently been described. To better delineate the role of epithelial NO, the authors of this study attempted to identify the cell type responsible for the production of NO in rat tracheal epithelium and human nasal epithelium.

CT and MR revealed a case of nasopharyngeal atresia, a malformation in which the soft palate is not formed, and the hard palate extends posteriorly to fuse with the anterior surface of the clivus, resulting in complete isolation of the nasal and oral cavities and the absence of a nasopharynx. We believe this rare anomaly results from abnormal persi...
The hypothesis that upper airway breathing behaviors generally follow the rules of a physiologic regulating system implies the existence of sensors that monitor the airway environment.

Seven patients who received pharyngeal flaps for velopharyngeal incompetence (VPI) were studied to assess the effect of the procedure on nasal airway size. The findings suggest that the pharyngeal flap does not significantly decrease the upper airway in all patients. The effect of the flap did not correlate with the type of cleft, and was most pron...
Clefts of the lip and palate frequently produce nasal deformities that tend to reduce the size of the nasal airway. Surgical correction of nasal, palatal, and pharyngeal structures may compromise breathing further. A significant number of individuals with cleft noses mouthbreathe to some extent because of the high prevalence of airway compromise.
