Presentation
At presentation, the father reported skull surgery during his infancy for unilateral lambdoid craniosynostosis. [ncbi.nlm.nih.gov]
Each entry follows a 5 section structure that will cover (1) essential features of the disorder (2) physiological basis of the disorder (3) neuropsychological and other clinical presentation (4) assessment and diagnostic practices (5) evidence-based treatments [books.google.com]
In 100% of cases, the chief complaint at this initial visit was a progressive skull deformity present since birth. [skullbaseinstitute.com]

Regular Uterine Contractions
(Preterm labor was defined as the onset of regular uterine contractions at any estimated gestation age less that 37 weeks.) [skullbaseinstitute.com]
Workup
By comparison, skull deformities due to premature fusion of the lambdoid suture persist and may become progressively worse, ultimately requiring corrective surgery.23 Recent increases in awareness and workup of posterior deformities have most likely contributed [skullbaseinstitute.com]
The imaging workup in cases of suspected craniosynostosis is affected by referral patterns. [pediatrics.aappublications.org]
WORKUP Lab Studies: No particular laboratory tests are specific to craniosynostosis. [razianesth.freeservers.com]
Sleep apnea may be central, obstructive, or of mixed origin; proper workup and assessment are crucial to the establishment of the correct diagnosis and treatment. * Central apnea may result from intracranial hypertension. [pocketdentistry.com]
Microbiology

Chlamydia
No significant differences were noted when results of routine prenatal laboratory studies (VDRL serology, gonococcal culture, chlamydia culture, rubella immunity, Hepatitis B surface antigen) were compared. [skullbaseinstitute.com]
Treatment
The experiences of 11 American families affected by craniosynostosis are chronicled, demonstrating the uniqueness of each case and each treatment. [books.google.com]
Age at treatment – Greater than 1 year of age. [craniofacial.ie]
Prognosis
Examines the initial clinical approach to suspected deformation problems, and then walks you through pathogenesis, diagnostic features, management, prognosis, and counseling for each condition. [books.google.com]

Treatment and prognosis Treatment is often with a cranioplasty. Abnormal intracranial pressure may affect neurocognition. Promoted articles (advertising) [radiopaedia.org]
Types 2 and 3 generally have severe neurological compromise, poor prognosis, early death, and sporadic occurrence. [onlinelibrary.wiley.com]

Etiology
The etiology has been attributed to genetic factors and primary disorders of bone growth, in addition to secondary effects of other diseases and modulators of the in utero environment. [thieme-connect.com]
Etiology Craniosynostosis has been estimated to occur in 1:2000 to 1:2500 births. [www2.aofoundation.org]
The etiology of craniosynostosis is heterogeneous. Isolated occurrence with unknown etiology is common, mostly affecting the sagittal suture. [ommbid.mhmedical.com]

Epidemiology and aetiology Craniosynostosis is a condition which is caused by the bones fusing too early, thus preventing the skull from expanding to accommodate the skull as required. [medic8.com]

This provides a platform for ongoing work to understand the processes of suture biogenesis and the pathophysiology of craniosynostosis mutations. [ommbid.mhmedical.com]
In the next few years, substantial progress is anticipated in this field, throwing new light on the underlying operative pathophysiological mechanisms in different forms of craniosynostosis. [razianesth.freeservers.com]

Inconsistencies in the recording of results prevented us from comparing ultrasound records between case and control groups for evaluation of fetal position, size, anomalies or intrauterine fluid volume levels throughout gestation. [skullbaseinstitute.com]
This early fusion prevents the skull from growing normally and affects the shape of the head and face.Many features of Crouzon syndrome result from the premature fusion of the skull bones. [ncbi.nlm.nih.gov]

Firstly, it will act as a protective cushion to prevent undue pressure on any one side of the head and allow for better distribution of the pressure along the bones of the skull. [sickkids.ca]
