Insights
CHARGE syndrome is an under-recognized cause of cleft lip and palate (CL/P). Infants with CHARGE syndrome often experience feeding difficulties and hearing loss, requiring specialized care.
Area of Science:
- Genetics
- Pediatric Surgery
- Craniofacial Anomalies
Background:
- Syndromic cleft lip and/or cleft palate (CL/P) presents complex management challenges in infants.
- CHARGE syndrome is a genetic disorder associated with various congenital anomalies.
Purpose of the Study:
- Determine the prevalence of CL/P in patients diagnosed with CHARGE syndrome.
- Identify factors influencing the management of CL/P in this specific pediatric population.
Main Methods:
- Retrospective review of patients diagnosed clinically and genetically with CHARGE syndrome from 1998 to 2016.
- Tabulation of clinical details including phenotypic anomalies, cleft types, surgical treatments, and outcomes.
Main Results:
- 25% of 44 CHARGE syndrome patients had cleft lip and palate; 1 had cleft palate only.
- Velopharyngeal insufficiency, feeding difficulties (requiring gastrostomy tubes), and neurosensory hearing loss were frequent.
- Associated anomalies included semicircular canal, auricular, cardiovascular, choanal atresia, and tracheoesophageal fistula.
Conclusions:
- CHARGE syndrome is an under-recognized genetic cause of CL/P.
- Infants with CHARGE syndrome frequently experience hearing loss, speech, and feeding difficulties.
- Delayed diagnosis can occur due to subtle phenotypic features.
Objective:
Infants with syndromic cleft lip and/or cleft palate (CL/P) often require more complex care than their nonsyndromic counterparts. Our purpose was to (1) determine the prevalence of CL/P in patients with CHARGE syndrome and (2) highlight factors that affect management in this subset of children.
Design:
This is a retrospective review from 1998 to 2016.
Patients:
Patients with CHARGE syndrome were diagnosed clinically and genetically.
Main Outcomes Measures:
Prevalence of CL/P was determined and clinical details tabulated: phenotypic anomalies, cleft types, operative treatment, and results of repair.
Results:
CHARGE syndrome was confirmed in 44 patients: 11 (25%) had cleft lip and palate and 1 had cleft palate only. Surgical treatment followed our usual protocols. Two patients with cardiac anomalies had prolonged recovery following surgical correction, necessitating palatal closure prior to nasolabial repair. One of these patients was too old for dentofacial orthopedics and underwent combined premaxillary setback and palatoplasty, prior to labial closure. Velopharyngeal insufficiency was frequent (n = 3/7). All patients had feeding difficulty and required a gastrostomy tube. All patients had neurosensory hearing loss; anomalies of the semicircular canals were frequent (n = 3/4). External auricular anomalies, colobomas, and cardiovascular anomalies were also common (n = 8/11). Other associated anomalies were choanal atresia (n = 4/11) and tracheoesophageal fistula (n = 2/11).
Conclusions:
CHARGE syndrome is an under-recognized genetic cause of cleft lip and palate. Hearing loss and speech and feeding difficulties often occur in these infants. Diagnosis can be delayed if the child presents with covert phenotypic features, such as chorioretinal colobomas, semicircular canal hypoplasia, and unilateral choanal atresia.
