Anatomy of the Ear01:16

Anatomy of the Ear

11.7K
Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...

Dimensional Analysis

61.8K
Dimensional analysis, also known as the factor label method, is a versatile approach for mathematical operations. The main principle behind this approach is: the units of quantities must be subjected to the same mathematical operations as their associated numbers. This method can be applied to computations ranging from simple unit conversions to more complex and multi-step calculations involving several different quantities and their units.

Endoscopic Studies II: Thoracocentesis

1.4K
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

Endoscopic Procedures I: Esophagogastroduodenoscopy

1.1K
An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:

The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

Area of Science:

  • Otolaryngology
  • Surgical Technology
  • Medical Imaging

Background:

  • Conventional two-dimensional (2D) endoscopy is standard for otologic surgery.
  • Advancements in imaging technology aim to improve surgical visualization and outcomes.

Purpose of the Study:

  • To assess the clinical utility and observer experience of a new computer-based 3D imaging system in otologic procedures.
  • To compare the 3D system with traditional 2D endoscopy regarding surgical outcomes and potential side effects.

Main Methods:

  • Eighteen otologic surgeries were performed using a 2D endoscope integrated with a novel 3D imaging system.
  • Operation duration and complications for chronic otitis media and attic cholesteatoma were compared between 2D and 3D approaches.
  • 35 observers completed questionnaires evaluating visual perception and comfort.

Main Results:

  • All surgeries proceeded successfully without conversion to 2D endoscopy.
  • No significant difference in operation duration was observed for chronic otitis media and attic cholesteatoma cases compared to 2D.
  • 94% of observers reported stereoscopic vision, 85% noted superior depth perception, and 97.1% experienced no visual fatigue.

Conclusions:

  • The computer-based 3D imaging system is effective for otologic surgery, offering enhanced 3D visualization.
  • The system demonstrated no significant side effects like visual fatigue or delays.
  • It aids in surgical performance, teaching, and learning of endoscopic ear surgery.
