CONGENITAL ANOMALIES Otolaryngology Neurological disorders Cardiovascular disorders Respiratory disorders Gastrointestinal disorders Genitourinary disorders
Choanal atresia Bilateral atresia: Cyanosis, alleviated by crying Respiratory distress Difficulty with feeding Unilateral atresia: Presented usually later in life Otolaryngology
Diagnosis Choanal atesia Fully examination head & neck Pass 6F soft catheter into nostril Minimize congestion by avoiding multiple attempts Direct examination into the nostrils (flexible fiberoptic bronchoscope)
Cleft lip ± palate
Cleft lip ± palate (CL/P) Etiology: failure of normal orofacial development during the 6 th -12 th wks of embryonic life Management: Pre-operative: feeding problem Encourage breast-feeding Other devices:Haberman Check weight gain frequently (weekly) Operative: 3-5 mo: closure lip, nasal, alveolar clefts 8-10 mo: palatoplasty Post-operative: prevention of infection
Pierre-Robin sequence Sequence: stunted growth of mandible → displacement of tongue → clefting of palate (roof of mouth) Airway patency problem, if severe → tracheostomy Feeding poblem, if severe, may need gastrostomy placement First stage repair:tongue- lip adhesion (glossopexy)
Pierre-Robin sequence Distraction Osteogenesis Tracheostomy After reconstruction
Neurological disorders Hydrocephalus Meningomyelocele
Congenital hydrocephalus: etiologies Accumulation of CSF Oversecretion of CSF: Papilloma of the choroid plexus Increased venous pressure Obstruction of CSF pathways Intraventricular block at the level of the foramen of Munro, 3rd ventricle, Sylvian aqueduct, or 4th ventricle Extraventricular block from inflammation or tumours Deficient resorption :Venous hypertension Abnormalities of the arachnoid villi Unknown mechanisms
Clinical presentation and Diagnosis Macrocephaly, rapid ↑ head circumference, large anterior and posterior fontanelle, splitting sutures CNS:lethargy, hypotonia, impaired gaze, poor feeding PE: ↑↑ HC, tense fontanelle, splitting sutures
Treatment Progressive: treatment (VP shunt) Aqueductal stenosis Myelomeningocele with associated Hydrocephalus Congenital communicating hydrocephalus Non-progressive (brain atrophy): no treatment Brain malformation: holoprosencephaly, lissencephaly Hydrancephaly Atrophy post infection
Meningocele: a protrusion of meninges only through a bony defect in the vertebral column Myelomeningocele: a protrusion of meninges and spinal cord through a bony defect in the vertebral column Spina bifida occulta: vertebral defect in the absence of spinal cord or meningeal herniation
Respiratory disorders Esophageal atresia and tracheoesophageal fistula Congenital diaphragmatic hernia
Tracheoesophageal fistula Fail of esophagotracheal septum to separate the esophagus and the trachea
Types of TEF Diagnosis: (1) NG insertion; (2) X-ray; (3) fluoroscopy; (4) bronchoscopy
Stabilization then transport Tracheoesophageal Fistula & Esophageal Atresia Head: keep at 45 0 angle Insert NGT & suction Avoid bag-mask, intubate if needed Prevent potential aspiration through fistula: minimize abdominal manipulation
Congenital Diaphragmatic Hernia A diaphragmatic defect occurs at 8-10 wks of gestation, owing to failure of closure of the pleuroperitoneal canal, thus the presence of the abdominal viscera in the thoracic cavity
Left : common – 70% (through foramen of Bochdalek) Initial treatment: stabilization of pulmonary function, prevention of PPHN Surgical repair: after CR stable Mortality ~40%
Stabilization then transport of congenital diaphragmatic hernia Avoid bag-mask & intubate promptly Insert NGT & suction Insert umbilical arterial and venous lines Nothing by Mouth (NPO) Transfer to the treatment center
Gastrointestinal disorders Gastroschisis Omphalocele Imperforate anus
How do you differentiate omphalocele and gastroschisis? omphalocele gastroschisis
Pathogenesis Gastroschisis: Umbilical veins 2 → 1 Left moves centrally Right: regresses and may creating a weak spot (~6wk of gestation) and created the defect when intestines returns into the abdominal cavity at ~10 th week of gestation) Teratogen exposure Genetic Omphalocele: Intestinal loops fail to return to the abdominal cavity at ~ 11 wk Due to abnormal embryonic development, thus high rate of associated defects & chromosomal abnormalities
Stabilization then transport Gastroschisis, Omphalocele Prevent hypothermia: cover with clear plastic, avoid gauze that usually stick to the bowel) Insert NGT & suction Prevent bowel ischemia: place the baby on side Prevent infection: start IV antibiotic : Ampicillin + Gentamycin Omphalocele: examine for Cardiac, Renal, Imperforate anus, Chromosome:Trisomy 13,18,21,Beckwith- Wiedemann Syndrome (large tongue, gigantism, hypoglycemia), CHARGE association. Gastroschisis: look for other intestinal atresia
Imperforate anus
Diagnosis & Treatment Dilatation for perineal or vestibular fistula All other fistulae required distal colostogram to determine the anatomy Colostomy for all other fistula Definitive reconstruction
Genitourinary disorders Bladder exstrophy Failure of midline fusion including deep structures eg. Symphisis pubis and bladder wall Surgery: Orthopedics Urologist Nephrologist and psychologist
