Skull thickness varies by gender and cleft type. Women with cleft lip (CL) had thinner occipital bones, while women with unilateral cleft lip and palate (UCLP) had thicker ones compared to controls.
Area of Science:
- Craniofacial anatomy
- Pediatric dentistry
- Orthodontics
Background:
- Cleft lip (CL), cleft palate (CP), and combined cleft lip and palate (UCLP) are common congenital conditions.
- Skull thickness variations may influence facial morphology and treatment outcomes in patients with clefts.
Purpose of the Study:
- To investigate and compare skull thickness in individuals with CL, CP, and UCLP.
- To identify potential gender-based differences in skull thickness within these cleft populations.
Main Methods:
- Retrospective analysis of skull thickness in four groups: CL, UCLP, CP, and a normal adult male control group.
- Comparison of skull thickness between genders within CL and UCLP groups.
- Comparison of CP group with the control group.
Main Results:
- Cleft lip (CL) women exhibited significantly thinner occipital bones than CL men.
- Women with unilateral cleft lip and palate (UCLP) showed significantly thicker occipital bones compared to control women.
- Significant gender differences in skull thickness were observed across different cleft types.
Conclusions:
- Skull thickness, particularly of the occipital bone, shows significant gender-related variations in patients with CL and UCLP.
- Observed occipital bone deviations in UCLP may correlate with documented jaw shape and position anomalies.

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...

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...
01:14Cranial 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...
