TREATMENT OF CRANIOSYNOSTOSES

This work evaluated the safety and effectiveness of operative techniques used in cranioplastic
surgery and outcomes of these surgical methods.
In study I the feasibility of endocranial fixation in frontal remodeling surgery for metopic and
coronal synostosis was established. Good to excellent aesthetic results were seen in 96% of cases
evaluated by a surgeon at the time of follow-up. Three patients out of 27 had complications
requiring revisions. No mortality or permanent morbidity, nor complications related to
endocranial placement of the plates were seen. Thus it was verified that placing resorbable
material intracranially reduces the aesthetic impact without hindering the final result.
Study II found that posterior cranial vault distraction procedures produced a mean increase of
25% in intracranial volume. This proved to be an effective technique for treating a variety of
craniosynostosis with significant shortage of intracranial volume. 3D photogrammetric imaging
was found to be a suitable non-ionizing method for evaluation of cranial volume increase
following distraction. In study III a new tool was developed and successfully used for the
intraoperative guidance of distractor device placement to ensure congruent vectors and thus
reduced complications of these surgical procedures.
In study IV long-term functional and aesthetic outcomes of the surgical treatment for sagittal
synostoses in patients reaching adulthood was examined. The mean follow-up time was 26.5 years
and the patients were 18 to 41 years old at the time of follow-up. The patients treated for sagittal
synostosis were equally satisfied with their facial appearance as were their age and gender
matched controls. Independent panels found patients’ appearance to be slightly less attractive, but
the difference was less than 10 mm on a 100 mm Visual Analogue Scale, representing a low
clinical significance. Patients’ socioeconomic situation such as education, housing, employment
and marital status equaled controls with similar frequencies of headaches, mental problems or
health issues as the controls.
