[Cranial suture ultrasound for reducing radiation exposure in diagnosis of craniosynostosis in young children].

UNLABELLED: Currently, there are no standards for examining patients with suspected craniosynostosis. CT of the brain with 3D skull reconstruction is a common approach to diagnose craniosynostosis in many hospitals. This technique in pediatric patients is associated with a high dose of ionizing radiation and prompts searching for other diagnostic methods.

OBJECTIVE

To generalize an experience of cranial suture ultrasound and compare diagnostic capabilities of various ultrasound devices.

MATERIAL AND

METHODS

We retrospectively analyzed data of cranial suture ultrasound in 49 patients under the age of 14 months with a suspected craniosynostosis. All patients underwent expert-class ultrasound. Of these, 10 patients underwent middle-class ultrasound. Age of these patients ranged from 2 to 10 months.

RESULTS

According to ultrasound data, we have found 48 synostotic sutures in 42 patients. There were 2 inaccurate results among these 48 sutures. In both cases, expert-class ultrasound confirmed partial closure of cranial sutures while 3D CT revealed their complete closure. Sensitivity and specificity of technique were 95.8% and 100%, respectively. Both expert- and middle-class ultrasound revealed synostotic sutures in 10 children under 1 year old.

CONCLUSION

Our data have shown that ultrasound of cranial sutures may be a first-line imaging technique. This method has high sensitivity and specificity in pediatric patients. Moreover, middle-class ultrasound devices may be used for diagnosis.
