Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

3.9K
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...

Measurement of Fluid Pressure01:16

Measurement of Fluid Pressure

419
Fluid pressure is commonly measured using devices called manometers, which rely on liquid columns to indicate pressure differences. The height of a liquid column in a manometer reflects the pressure exerted by the fluid, providing a simple yet effective means of measurement. Different types of manometers serve specific purposes based on their configurations and the type of fluids involved.
A basic form of manometer is the piezometer, a vertical tube open at the top and filled with the same...

Pressure Relationships in Thoracic Cavity01:24

Pressure Relationships in Thoracic Cavity

4.7K
Breathing, otherwise known as pulmonary ventilation, is the process of air movement into and out of the lungs. The main mechanisms propelling pulmonary ventilation are atmospheric pressure (Patm), intra-pulmonary (Ppul ) or intra-alveolar pressure (Palv) within the alveoli, and intrapleural pressure (Pip) within the pleural cavity.
Breathing Mechanisms
Both intra-alveolar and intrapleural pressures rely on specific lung properties. The ability to breathe—allowing air to enter the lungs...

Temperature Measurement Sites

2.7K
A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...

Assessing Body Temperature - Tympanic membrane01:14

Assessing Body Temperature - Tympanic membrane

940
Assessing tympanic membrane temperature involves using a tympanic membrane thermometer (TMT). Here is a step-by-step guide:
Step 1: Begin by practicing good hand hygiene to prevent the transmission of microorganisms.
Step 2: Turn on the thermometer and wait until the ready sign appears on the screen to ensure accurate measurement.
Step 3: Slide the probe cover in place to prevent cross-contamination.
Step 4: Instruct the patient to tilt their head to the side for comfort and check for cerumen...

Here is a stepwise guide to assessing the body temperature at the temporal artery using a temporal artery thermometer
Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.  
Step 3: Assess the patient's...

Summary
This summary is machine-generated.

Cochlear implant (CI) electrode insertion speed impacts intracochlear pressure and force differently. Slow insertion increases hydraulic pressure but decreases cochlear wall force, leaving optimal speed unclear for preserving residual hearing.

Area of Science:

  • Otoacoustic emissions
  • Cochlear implant surgery
  • Inner ear biomechanics

Background:

  • Residual hearing loss is a risk in cochlear implant (CI) surgery.
  • Intracochlear hydraulic pressure and cochlear wall force may influence hearing preservation.
  • Understanding insertion mechanics is crucial for minimizing trauma.

Purpose of the Study:

  • To compare peak hydraulic pressure and cochlear wall force during CI electrode insertion using varied techniques.
  • To evaluate the impact of insertion speed, method, and approach on intracochlear biomechanics.

Main Methods:

  • Utilized twenty fresh frozen temporal bones for ex vivo analysis.
  • Measured hydraulic pressure and cochlear wall force during straight electrode insertions.
  • Compared slow vs. fast insertion speeds, manual vs. automatic insertion, and round window approach (RWA) vs. extended RWA (ERWA).

Main Results:

  • Slow insertion significantly increased peak hydraulic pressure (239% RWA, 58% ERWA) compared to fast insertion.
  • Slow insertion reduced peak cochlear wall force by 29% compared to fast insertion.
  • Insertion method and approach (RWA vs. ERWA) did not significantly affect outcomes.

Conclusions:

  • Contradictory effects of insertion speed on hydraulic pressure and cochlear wall force were observed.
  • The optimal insertion speed for minimizing trauma and preserving residual hearing remains undetermined.
  • Further research is needed to elucidate the safest CI electrode insertion technique.
