Objective:
Craniosynostosis is a congenital skull deformity that impacts development and quality of life of children if left untreated. This study aimed to evaluate literature regarding presentation, treatment, and outcomes of craniosynostosis in Africa.
Methods:
A systematic review of the literature using PubMed/MEDLINE, Scopus, Web of Science, and Google Scholar databases was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.
Results:
Fourteen retrospective/prospective studies with 620 patients and 14 case reports involving 27 cases (8 countries) were included. In 12 articles, 56.6% of patients (317/560) were males, with a mean age of 2.4 years (confidence interval [CI]: 1.1-3.7). Abnormal head shape was the most reported presentation in 77.8% of cases (332/427, 8 articles). Syndromic craniosynostosis was seen in 25.2% (CI: 13.7%-36.6%). Common phenotypes were trigonocephaly in 31.5% (CI: 3.6%-59.4%), anterior plagiocephaly in 23.2% (CI: 5.1%-41.3%), and scaphocephaly in 22.1% (CI: 13.5%-30.8%). Five hundred seventy eight patients, 99.5% (CI: 99.0%-100.0%), underwent surgical treatment. Vault remodeling was performed in 72.9% patients (CI: 47.4%-98.6%). Postoperative complications included cerebrospinal fluid leaks 5.4% (CI: 0.0%-11.6%) and surgical site infections 4.5% (CI: 0.0%-10.8%). Follow-up ranged between 0.2 and 40.9 months; 95.6% of cases (CI: 90.1%-100.0%) exhibited improved deformity and neurological deficits at last follow-up. The mortality rate was 3.1% (CI: 0.0%-6.9%, 2 articles).
Conclusions:
Few studies on craniosynostosis in Africa highlight the need for more research. Treatment with open techniques yields few complications and a low mortality rate. Early diagnosis and collaborative data reporting will enhance understanding of its burden and variations across Africa.

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,...
01:08Overview of the Skull
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...
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...
