Insights

The foramen of Huschke (FH), an opening in the temporal bone, persists in 12% of men and 20% of women. Its incidence decreases with age, suggesting natural closure over time.

Area of Science:

  • Anatomy
  • Anthropology
  • Otolaryngology

Background:

  • The foramen of Huschke (FH) is an anatomical feature of the temporal bone, typically closing by age five.
  • Persistent FH can lead to temporomandibular joint (TMJ) herniation, salivary fistulas, and ear injuries during TMJ arthroscopy.

Purpose of the Study:

  • To investigate the age and gender-specific prevalence of persistent foramen of Huschke (FH) in Japanese adults.
  • To understand the anatomical variations and potential clinical implications of a persistent FH.

Main Methods:

  • Analysis of 1994 temporal bones from 997 Japanese dry skulls.
  • Examination of persistent FH presence, correlating findings with age and gender.

Main Results:

  • A persistent FH was identified in 12% of males and 20% of females.
  • A statistically significant female predominance (P<0.0001) was observed for persistent FH.
  • The incidence of persistent FH decreased with increasing age in both genders.

Conclusions:

  • Persistent foramen of Huschke (FH) is more common in women and its prevalence declines with age.
  • The findings suggest that the foramen of Huschke may continue to close even after childhood.
  • Understanding persistent FH prevalence is crucial for preventing TMJ-related complications and surgical injuries.

Sutures of the Skull01:22

Sutures of the Skull

The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
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...

Changes in the Appendicular Skeleton with Age

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Cranial Bones: Lateral View

The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
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...
Anatomy of the Brain: Ventricles01:18

Anatomy of the Brain: Ventricles

There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen. The...

Cranial Bones: Superior and Posterior View

The superior view of the cranium shows the frontal and paired parietal bones.
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,...
Olfactory Receptors: Location and Structure01:03

Olfactory Receptors: Location and Structure

The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...
