Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

7.4K
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...

Cranial Bones: Superior and Posterior View01:14

Cranial Bones: Superior and Posterior View

8.0K
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,...

Anatomy of Respiratory System I: Upper Respiratory Tract

5.6K
The upper respiratory tract plays a vital role in the respiratory system, comprising several structures that facilitate air intake and prepare air for the lungs. It also serves as the first line of defense against pathogens and particles. This tract includes the nose and nasal cavity, the oral cavity, the paranasal sinuses, and the pharynx, each with specific functions and features.
Nose and nasal cavity
The nose and nasal cavity represent the main external openings of the respiratory tract....

Nose and Nasal Cavity01:24

Nose and Nasal Cavity

12.6K
The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...

Anatomy of the Brain: Ventricles01:18

Anatomy of the Brain: Ventricles

9.4K
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.

Area of Science:

  • Otolaryngology
  • Medical Education
  • Anatomy

Background:

  • Frontal sinus anatomy presents significant teaching and learning challenges.
  • Traditional surgical training methods are insufficient for complex frontal sinus procedures.
  • A novel educational module, the Frontal Sinus Masterclass (FSMC), was developed to address these issues.

Purpose of the Study:

  • To evaluate the effectiveness of the Frontal Sinus Masterclass (FSMC) in improving otolaryngology residents' understanding of frontal sinus anatomy.
  • To assess the impact of the FSMC on residents' ability to interpret CT scans of the frontal sinus.
  • To determine if the FSMC enhances residents' confidence in performing frontal sinus surgery.

Main Methods:

  • The study involved otolaryngology residents at two academic centers.
  • A pretest assessed baseline knowledge, followed by the FSMC course utilizing a 3D conceptualization module, CT scan analysis, and surgical video demonstrations.
  • A posttest evaluated knowledge acquisition and anatomical assessment skills after the course.

Main Results:

  • Participant knowledge of the frontal sinus drainage pathway improved from 42% to 63% (P=0.054).
  • Anatomical assessment accuracy increased from 61% to 68% (P=0.047), and overall assessment improved from 52% to 66% (P=0.016).
  • Residents demonstrated improved ability to recognize frontal recess cells on CT scans, with correct answers increasing from under 50% to over 66%.

Conclusions:

  • The FSMC effectively enhanced residents' ability to recognize frontal sinus anatomy on CT scans.
  • Participants reported subjective benefits, including increased confidence in their surgical abilities.
  • The building block approach of the FSMC is a valuable tool for teaching complex frontal sinus anatomy.
