Study Notes
Causes of Craniostenosis
- Genetic mutations: Alterations in genes that control skull development, such as FGFR2, FGFR3, and TWIST1
- Environmental factors: Maternal smoking, alcohol consumption, and certain medications during pregnancy
- Chromosomal abnormalities: Conditions like Apert syndrome, Crouzon syndrome, and Pfeiffer syndrome
- Syndromic craniostenosis: Occurs in combination with other congenital anomalies, such as facial deformities or limb abnormalities
Symptoms of Craniostenosis
- Abnormal head shape: Brachycephaly (short and wide), scaphocephaly (long and narrow), or trigonocephaly (triangular)
- Delayed fontanelle closure: Soft spots on the skull that fail to close within the expected timeframe
- Increased intracranial pressure: Leading to headaches, vomiting, and seizures
- Developmental delays: Delayed speech, language, and cognitive skills
- Vision problems: Strabismus (crossed eyes) and optic nerve damage
Diagnosis of Craniostenosis
- Physical examination: Evaluation of head shape, facial features, and fontanelle closure
- Imaging studies: CT or MRI scans to assess skull shape and brain structure
- Genetic testing: To identify genetic mutations or chromosomal abnormalities
- Measurement of head circumference: To monitor growth and development
Surgery Options for Craniostenosis
- Cranial vault remodeling: Reconstruction of the skull to improve shape and size
- Strip craniectomy: Removal of a portion of the skull to allow for expansion
- Frontal orbital advancement: Surgery to reposition the forehead and eye sockets
- Distraction osteogenesis: Gradual separation of the skull bones to increase space
Rehabilitation after Craniostenosis Surgery
- Pain management: Medication and monitoring to minimize discomfort
- Wound care: Regular cleaning and dressing changes to promote healing
- Physical therapy: To improve motor skills, balance, and coordination
- Speech and language therapy: To address developmental delays and communication difficulties
- Follow-up appointments: Regular check-ins with the surgeon and other healthcare professionals to monitor progress and address any complications
Causes of Craniostenosis
- Genetic mutations in genes like FGFR2, FGFR3, and TWIST1 affect skull development
- Maternal smoking, alcohol consumption, and certain medications during pregnancy are environmental factors
- Chromosomal abnormalities, such as Apert syndrome, Crouzon syndrome, and Pfeiffer syndrome, contribute to craniostenosis
- Syndromic craniostenosis occurs with other congenital anomalies, like facial deformities or limb abnormalities
Symptoms of Craniostenosis
- Abnormal head shapes, including brachycephaly, scaphocephaly, and trigonocephaly
- Delayed fontanelle closure, where soft spots on the skull fail to close on time
- Increased intracranial pressure leads to headaches, vomiting, and seizures
- Developmental delays include delayed speech, language, and cognitive skills
- Vision problems, such as strabismus and optic nerve damage, occur

Hydrocephalus
Causes
- Congenital hydrocephalus is present at birth, often due to genetic defects or maternal infections during pregnancy
- Acquired hydrocephalus develops after birth, often due to head trauma, infections, tumors, bleeding in the brain, or cerebrovascular accidents
- Idiopathic normal pressure hydrocephalus (iNPH) is a type of acquired hydrocephalus, often affecting older adults
Symptoms
Infants and Children
- Enlarged head circumference
- Bulging soft spots on the head (fontanelles)
- Sleep disturbances
- Vomiting
- Irritability
Adults
- Headaches
- Nausea and vomiting
- Blurred vision
- Difficulty walking or balance problems
- Memory loss or cognitive impairment
- Seizures
Idiopathic Normal Pressure Hydrocephalus (iNPH)
- Urinary incontinence
- Difficulty walking (gait disturbances)
- Cognitive decline (e.g., memory loss, confusion)
Diagnosis
- Imaging studies, such as CT or MRI scans, are used to visualize the brain and ventricles
- Ultrasound is used for infants
- Physical examination includes measuring head circumference and checking for signs of increased intracranial pressure (e.g., papilledema)
- Lumbar puncture is used to measure cerebrospinal fluid (CSF) pressure and collect a sample for analysis
- CSF analysis is used to rule out infections or other conditions that may mimic hydrocephalus
