The literature data on the incidence of pneumatization of the crista galli based on patients' computed tomography (CT) scans ranges from 3 to 37.5%. This study investigated for the first time the incidence of crista galli pneumatization based on CT scans of human skulls. The study examined 102 randomly selected human skulls (≥20 years of age; 76 males, 26 females). Skulls were scanned in a fixed position using cone beam computed tomography (CBCT) with a field of view of 145 × 130 mm and an isotropic voxel size of 0.25 mm. The scans were recorded in Digital Images and Communications in Medicine format. The CBCT images were analyzed using OnDemand3DTM software. A 2-mm contiguous slice thickness was used in the axial and coronal planes. The width, length, and height (cranial-caudal dimension) of the pneumatized space within the crista galli were measured. The crista galli was found to be pneumatized in even 68 (66.6%) of the 102 skulls. Two types of pneumatized crista galli (PCG) were identified: PCG alone (surrounded by bony walls) and PCG + spongiosis (surrounded by spongy bone). Of the 68 pneumatized skulls, 31 were PCG alone (45.58%) and 37 were PCG + spongiosis (54.42%). The pneumatized regions had a width of 0.9-6.6 mm, length of 2.8-12.9 mm, and height of 3.6-17.1 mm. No statistically significant differences have been found regarding the sex and age. Regarding the proportions of pneumatization, the three types of crista galli have been determined resulting in new, practical classification: type S (small), type M (moderate), and type L (large). The crista galli is not always a compact bone; in some cases, it is filled with spongy bone or pneumatized. In respect of proportions of pneumatization, there are three types of pneumatized crista galli: small, moderate, and large. Pneumatized crista galli can play an important role in clinical work, both as an inflamed sinus or other pathologies (sinusitis cristae galli, mucocoelae) or as a morphologic barrier in neurosurgical approaches to some tumors of the anterior skull base.

Morphometric evaluation of the anterior cranial fossa during the prenatal stage in humans and its clinical implications.

The study examines the morphometric development of the anterior cranial fossa in human fetuses and its clinical implications. The anterior cranial fossa, crucial for protecting the frontal lobes, was analyzed during prenatal development using innovative computer image processing techniques. We hypothesized that the growth of the anterior cranial fossa is not uniform throughout fetal development and that changing geometric relationships are important for possible therapeutic interventions in cases of congenital defects.

Article Synopsis
- This study investigated how the crista galli (CG) structure changes in children aged 1-18 as they grow older, using CT imaging from 180 subjects equally split by gender.
- Key measurements of the CG's width, height, and length showed significant growth in height and length with age, while width remained stable.
- Various morphological types were identified, with Type 2 being the most common, and the presence of pneumatized CGs was found only in older children, indicating that these structural changes occur primarily after early childhood.
Cribriform Plate Foramina Count in Patients With Acquired and Congenital Anosmia.
Am J Rhinol Allergy
January 2025
Smell and Taste Clinic, Department of Otorhinolaryngology, Technical University of Dresden, Dresden, Germany.
Background: Cribriform foramina provide the openings for olfactory nerve fibers to cross from the nasal cavity to the olfactory bulb. Disruption of the olfactory nerve fibers is known to affect olfactory function, but little is known about the potential effects on the number of cribriform foramina in congenital anosmia.
Objective: This pilot study aimed to investigate whether there was a reduction in foramina in patients with acquired and congenital anosmia (including both Kallmann syndrome and isolated congenital anosmia) compared to controls with normal olfactory function.

Department of Anatomy, Faculty of Medicine, Gaziantep University, Gaziantep.
Objective: To determine alterations in the crista galli (CG) size in fetuses with advancing weeks.
Methods: Skull bases of 32 fetuses (11 males/21 females) aged 17 to 32 weeks in utero were included in the study. The width (width of CG), height (height of CG), and length (length of CG) of CG were measured, and also olfactory fossa depth (OFD) was measured to determine the relation of CG with OFD.

Article Synopsis
- The study aimed to determine the exact position of the posterior clinoid process (PCP) in fetuses by measuring its distances to various reference points in the skull base of 32 fetuses (11 males and 21 females) aged 17 to 32 weeks.
- Measurements showed that the PCP’s distance from various skull features differed slightly by gender and increased significantly with gestational age, indicating growth dynamics of these distances.
- The research provides linear equations that can be used to estimate how the distances from the PCP change as the fetus develops, which may aid in understanding anatomical variations in fetuses.
