Objective:
The morphology of the frontal sinus (FS) has long been debated as a determinant of fracture type and severity. This study aimed to evaluate the association between sinus dimensions, fracture patterns, and clinical outcomes using real-world data.
Study Design:
Retrospective cohort study.
Setting:
Tertiary trauma referral center.
Methods:
We retrospectively reviewed the records of 48 frontal sinus fractures treated at a tertiary trauma center. Volumetric and dimensional measurements (volume, height, width, and anteroposterior depth) were obtained from CT scans. Each sinus was segmented and analyzed separately using 3D Slicer software. Sinuses were categorised according to cohort-derived percentiles and established classifications. Associations between sinus anatomy, fracture type, and outcomes were analyzed using logistic regression.
Results:
While most sinus dimensions showed odds ratios greater than 1 for anterior table fractures, only the categorical analysis of sinus height demonstrated statistical significance. Cohort-based high sinuses (≥ 22.22 mm) were associated with isolated anterior table fractures (p = 0.014, OR = 4.83, 95% CI: 1.38-16.9). When comparing sinuses with larger volumes, a similar trend towards anterior-only fractures was observed, though not statistically significant. Patients with anterior-only fractures had fewer displaced fractures, shorter hospitalisation, and lower rates of intracranial haemorrhage and ICU admission.
Conclusion:
Frontal sinus height appears to be the most clinically relevant parameter influencing fracture patterns. Vertically expanded sinuses may act as protective "crumple zones," mitigating posterior table involvement and severe intracranial injury.

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...
