Insights

This study found no link between high jugular bulb (HJB) and mastoid air cell volume. Further research is needed to confirm if HJB impacts mastoid development or disease.

Area of Science:

  • Radiology
  • Otolaryngology
  • Anatomy

Background:

  • High jugular bulb (HJB) is an anatomical variation of the temporal bone.
  • Mastoid pneumatization refers to the air cell development within the mastoid bone.
  • Understanding the relationship between these two can offer insights into temporal bone development and pathology.

Purpose of the Study:

  • To investigate the correlation between the degree of high jugular bulb (HJB) and mastoid pneumatization.
  • To analyze temporal bone anatomy using high-resolution computed tomography (HRCT).

Main Methods:

  • Retrospective analysis of HRCT scans from 1,025 patients (April 2019 - June 2022).
  • Inclusion of 113 patients with HJBs, categorized into Grade I, II, and III based on anatomical location.
  • Mastoid pneumatization volume assessed using 3D reconstruction from HRCT images.

Main Results:

  • No statistically significant difference in mastoid cell volume was found across different grades of HJB (p = 0.165).
  • Grade II HJB was the most prevalent classification (49.7%).
  • The study included 32 males and 81 females, with a mean age of 41.2 years.

Conclusions:

  • No correlation was identified between mastoid air cell volume and the degree of high jugular bulb.
  • HJB may not influence mastoid air cell development or the occurrence of related diseases.
  • Findings are exploratory and warrant further extensive cross-sectional studies.

Veins of Head and Neck01:19

Veins of Head and Neck

The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...

Cranial Bones: Lateral View01:27

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...

Arteries of the Head and Neck01:26

Arteries of the Head and Neck

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

Cranial and Spinal Meninges

The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

Pneumothorax-II01:27

Pneumothorax-II

Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.

Respiratory System Abnormal Finding II: Palpation and Auscultation

In assessing respiratory abnormalities, palpation and auscultation are critical tools for detecting and interpreting various pathophysiological changes. These techniques provide insight into underlying disorders by evaluating tactile sensations and sounds produced by the respiratory system.
