Summary
Pterional craniotomy offers a flexible skull base approach for accessing critical brain regions. This technique emphasizes efficient surgical target access with minimal anatomical disruption, enhanced by 3D virtual reality models.
Area of Science:
- Neurosurgery
- Skull Base Surgery
Background:
- Pterional craniotomy is a fundamental cranial operative corridor.
- It provides excellent exposure of the anterior cranial fossa, circle of Willis, and interpeduncular region.
Purpose of the Study:
- To summarize an efficient execution and expansion of the pterional craniotomy.
- To demonstrate the surgical corridor using 3-dimensional virtual reality models.
Main Methods:
- The presentation focuses on the strategic use of dynamic retraction.
- It highlights minimizing disruption of normal anatomy during surgical access.
Main Results:
- Pterional craniotomy can obviate the need for more extensive approaches like orbitozygomatic osteotomy in select cases.
- Efficient execution and expansion of the pterional route are demonstrated.
Conclusions:
- The pterional approach is a versatile skull base technique.
- Focusing on surgical target achievement with minimal disruption is key.
- 3D virtual reality enhances understanding of the surgical corridor.

Electrochemistry is the science involved in the interconversion of electrical and chemical reactions. Such reactions are called reduction-oxidation, or redox reactions. These important reactions are defined by changes in oxidation states for one or more reactant elements and include a subset of reactions involving the transfer of electrons between reactant species. Electrochemistry as a field has evolved to yield sufficient insights on the fundamental principles of redox chemistry and multiple...

1.2K
The human body gets energy from the three macronutrients: carbohydrates, proteins, and fats. Energy is released when the chemical bonds in the organic compounds present in the food are broken down. The energy content of food is measured in kilocalories (kcal), defined as the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius. This value is determined by measuring the temperature change of the water surrounding a calorimeter after the complete...

The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

01:29Disorder of Water Balance
2.4K
Water balance disorders are medical conditions that occur when there is a deviation from the body's water volume or osmolarity, disrupting normal homeostasis and leading todehydration, hypotonic hydration, hyperhydration, edema, or water intoxication.
Dehydration
Dehydration occurs when the body loses fluids (particularly water).
Causes:
The major causes of dehydration include excessive sweating, fever, vomiting, diarrhea, and diuresis.
Signs and Symptoms:

01:25Acid-Base Balance
2.3K
The human body maintains a narrow pH range regulated through acid-base balance. This balance is crucial as changes in the hydrogen ion concentration can disrupt cell membrane stability, alter protein structures, and change enzyme activities. The normal pH of arterial blood is 7.4, venous blood and interstitial fluid is 7.35, and intracellular fluid averages 7.0.
When the pH of arterial blood rises above 7.45, it results in a condition called alkalosis. Conversely, a drop below 7.35 leads to...
