Abstract
Background: Minimally invasive strip craniectomy is a well-established treatment for sagittal craniosynostosis; however, the temporality of change in head shape has not been assessed. In this study, the authors performed head shape analysis to compare time-series-based clinical outcomes among 3 different surgical techniques across 3 academic centers for the treatment of sagittal craniosynostosis.
Methods: Retrospective, longitudinal 3-dimensional (3D) images were collected from patients who underwent surgery for the correction of sagittal craniosynostosis for up to 5 years postoperation. The surgical methods studied include spring-assisted craniectomy, narrow-strip craniectomy plus orthotic helmet therapy, and wide-strip craniectomy with biparietal and bitemporal barrel stave wedge osteotomies plus orthotic helmet therapy. Postoperative 3D images were binned into 6 age groups. Cranial index measurements were calculated on 3D images. The 3D whole-head composite images were generated for each procedure to visually represent longitudinal outcomes.
Results: The median (interquartile range) cranial index measurements at 3- to 5-years postoperative follow-up were 75.9 (73.1 to 78.6) for spring-assisted, 75.9 (75.4 to 78.5) for narrow-strip, and 79.4 (76.4 to 81.9) for wide-strip procedures. The wide-strip cranial index was significantly different from the spring-assisted and narrow-strip groups ( P < 0.001). Concerning 3D analysis, patients receiving spring-assisted procedures showed normalization of frontal bossing and skull height compared with age-matched controls, whereas patients receiving wide-strip procedures showed greater correction of occipital bulleting. Patients receiving narrow-strip procedures had intermediate results between these outcomes.
Conclusions: There was no statistically significant regression in longitudinal cranial index measurements across the 3 techniques aimed at treating sagittal craniosynostosis. Longitudinal comparison of 3D head shape outcome demonstrated satisfactory correction of scaphocephalic deformity across all 3 surgical groups.
Clinical question/level of evidence: Therapeutic, III.
期刊介绍：
For more than 70 years Plastic and Reconstructive Surgery® has been the one consistently excellent reference for every specialist who uses plastic surgery techniques or works in conjunction with a plastic surgeon. Plastic and Reconstructive Surgery® , the official journal of the American Society of Plastic Surgeons, is a benefit of Society membership, and is also available on a subscription basis.
Plastic and Reconstructive Surgery® brings subscribers up-to-the-minute reports on the latest techniques and follow-up for all areas of plastic and reconstructive surgery, including breast reconstruction, experimental studies, maxillofacial reconstruction, hand and microsurgery, burn repair, cosmetic surgery, as well as news on medicolegal issues. The cosmetic section provides expanded coverage on new procedures and techniques and offers more cosmetic-specific content than any other journal. All subscribers enjoy full access to the Journal''s website, which features broadcast quality videos of reconstructive and cosmetic procedures, podcasts, comprehensive article archives dating to 1946, and additional benefits offered by the newly-redesigned website.
