“…The frontal branches of the MMA that crossed the floor of the skull base passed through the lateral margin of the sphenoparietal sinus, and were directed laterally to supply the dura mater of the frontotemporal region. The region in which the NS terminated and where the frontal branches of the MMA exited the anterolateral territory of the middle cranial fossa coincided with the pterion, which is where the frontal, sphenoid, parietal and squamous parts of the temporal bones meet (Oguz et al, 2004 ; Schwartz et al, 2008 ). Before reaching the pterion, the frontal branches of the MMA and the nerve bundle of the NS ran alongside the floor of the middle cranial fossa parallel to the sphenosquamosal suture, which is the posterior border of the greater wing of the sphenoid bone.…”

Macroscopic Innervation of the Dura Mater Covering the Middle Cranial Fossa in Humans Correlated to Neurovascular Headache

The trigeminovascular system within the cranial dura mater is a possible cause of headaches. The aim of this study is to investigate macroscopically dural innervation around the middle meningeal artery (MMA) in the middle cranial fossa. Forty-four sides of the cranial dura overlying the skull base obtained from 24 human cadavers were stained using Sihler’s method. Overall, the nervus spinosus (NS) from either the maxillary or mandibular trigeminal divisions ran along the lateral wall of the middle meningeal vein rather than that of the MMA. Distinct bundles of the NS running along the course of the frontal branches of the MMA were present in 81.8% of cases (N = 36). Others did not form dominant nerve bundles, instead giving off free nerve endings along the course of the MMA or dural connective tissue. The distribution of these nerve endings was similar to that of the course of the frontal, parietal and petrosal branches of the MMA (11.4%). The others were not restricted to a perivascular plexus, crossing the dural connective tissues far from the MMA (6.8%). These findings indicate that the NS generally travels alongside the course of the frontal branches of the MMA and terminates in the vicinity of the pterion.

“…The sutural morphology was classi ied into two types: Type -I where a sutural bone was present and Type -II where the sutural bone was absent. It is imperative to know about these bones because they can mislead in the identi ication of fracture of skull bones in medico-legal cases and may confuse the surgical orientation if present in the asterion (Soames et al, 2004).Hence the study of sutural morphology of asterion was planned.…”

Sutural bones are usually small, irregularly shaped bones, often found in sutures of the cranium. It is important to know about them as they may complicate the surgical orientation if present in the asterion. The study aims to observe the incidence of the sutural morphology of asterion in dry human skulls. Total 120 human adult dry skulls consisting of 80 male and 40 female skulls were analyzed for Type-I and Type-II asterions. out of 120 skulls, (n=240) Type-I asterion was observed in 36 (15%) skulls, and Type-II was observed in 204 (85%) skulls. Type-I was 28 (17.5%) in males, 8 (10.0%) in females and 36 (15.0%) in total skulls. Type-II was 132 (82.5%) in males, 72 (90.00%) in females and 204 (85.0%) in total skulls. In the present study, the incidence of Type-I asterion was found more in males than females. The study can be useful to neurosurgeons, forensic experts, anthropologists and radiologists.

“…The pterion is an anatomical region located in the temporal fossa, where the frontal, sphenoid, temporal and parietal bones join (URZÌ, IANNELLO, TORRISI et al, 2003). The pterion is of great relevance and it has been studied since the 19th century (SUTTON, 1884), being used as a landmarker to several brain regions (OGUZ, SANLI, BOZKIR et al, 2004). It is located about 4.0 cm above the zigomatic arch and 3.5 cm behind the frontozigomatic suture.…”

Introduction: The pterion is an anatomical region located in the temporal fossa between frontal, sphenoid, and temporal bones. In the literature, we observed that the pterion can suffer many anatomical variations which depend on several factors, such as gender and ethnicity, and its form can vary in relation to the skull side. Objectives: To study and analyze the variations that can occur in the pterion, related to the type and symmetry, in relation to gender, age, side of the skull and ethnicity. Materials and Methods: We examined 55 skulls of both sexes belonging to the Department of Skulls Museum of Anatomy Descriptive and Topographic UNIFESP. The Pterions were outlined with pencil on tracing paper and from this drawing and the information of each skull perform our analysis. Results: In our sample, the pterion types vary as follows: sphenoparietal (90%), frontotemporal (4.54%), epiteric (3.64%) and stellate (1.82%). The most common types of female skulls were sphenoparietal (85%), and the least common types were stellate (2.5%). For the male skulls, the most common types were sphenoparietal (92.86%), and the least common types were stellate (1.43%). For the skull of white subjects, the most common types were sphenoparietal (98.08%), and the least common types were frontoparietal (1.92%). For the skull of non-white subjects, the most common types were sphenoparietal (82.75%), and the least common types were stellate (3.45%). Conclusion: We concluded that the most common pterions found in the entire sample were the sphenoparietal being predominant in sex, ethnicity, and side but there are variations in relation to the least common pterion types taking into consideration side, sex, and ethnicity.
