Background:
Complications of cranial distraction techniques can arise perioperatively. This study assessed long-term clinical outcomes following cranial distraction for craniosynostosis. We analyzed factors involved in those complications.
Methods:
We retrospectively assessed outcomes from 120cases treated with cranial distraction for craniosynostosis between 1997 and 2019. Age at surgery, type of craniosynostosis, length of advancement, and complications were reviewed. We analyzed cases in which clinical characteristics and medical data appeared to increase the risk of complications.
Results:
Of the 120 patients (65 males, 55 females), 79 had syndromic craniosynostosis and 41 had nonsyndromic craniosynostosis. Type of craniosynostosis was scaphocephaly in 17 patients, trigonocephaly in 4, plagiocephaly in 15, brachycephaly in 57, oxycephaly in 14, cloverleaf in 10, and others in 3. Mean age at surgery was 18.6 months (range, 3-525 months). Mean total length of advancement was 32.3 mm (range, 5.5-62.0 mm). No deaths were encountered. Complications included cerebrospinal fluid leaks in 5 patients, epidural abscess in 1, local infections in 33, device problems in 20, erosions and/or ulcers in 23 and decubitus ulcers in 8.Comparisons of complications and factors: Local infection showed no significant correlation with type of craniosynostosis, nor with the total length of advancement. Plate displacement showed significant relationships with total length of advancement, or with age at surgery (P < 0.01).
Conclusion:
These results suggested that local infection occurred independent of the type of craniosynostosis. Plate displacement and ulcers appear to occur more easily among patients with longer lengths of advancement or with surgery at a younger age, due to the weakness of the cranial bones.

01:22Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
01:14Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
01:27Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
