Summary
A staged surgical approach offers a safe and effective method for resecting challenging petroclival meningiomas. This two-stage technique minimizes surgical morbidity and achieves gross total tumor removal.
Area of Science:
- Neurosurgery
- Oncology
Background:
- Petroclival meningiomas are rare and difficult to surgically access.
- High surgical morbidity is associated with traditional approaches.
Purpose of the Study:
- To demonstrate a staged surgical resection technique for petroclival meningiomas.
- To evaluate the safety and efficacy of this approach.
Main Methods:
- A two-stage surgical resection was performed for a large petroclival meningioma.
- The first stage involved an anterior petrosectomy; the second stage utilized a retrosigmoid craniotomy for residual tumor removal.
Main Results:
- The patient tolerated both surgical stages well with only transient diplopia.
- Postoperative MRI confirmed gross total resection of the meningioma.
Conclusions:
- A staged surgical approach is a safe and effective strategy for managing petroclival meningiomas.
- This method is well-tolerated by patients and facilitates surgical resection.

01:22Stages of General Anesthesia

Various sedation levels offer significant advantages in facilitating procedural interventions for patients undergoing medical or invasive surgical procedures. These levels span from anxiolysis to general anesthesia, providing a spectrum of sedative effects to cater to specific patient needs. Anxiolysis reduces anxiety and is achieved through minimal sedation, enabling patients to remain awake and responsive while feeling more at ease during the procedure. This level can benefit minor...

01:22Stages of Sleep
1.4K
Sleep progresses through distinct stages, each characterized by specific brain wave patterns and physiological responses ranging from wakefulness to stages of non-rapid eye movement, known as non-REM, to rapid eye movement, referred to as REM. Understanding these stages helps in recognizing how sleep supports various bodily and cognitive functions.
Before sleep begins, in wakefulness, the brain exhibits primarily beta waves, which are high in frequency and low in amplitude, indicating alertness...

Stages of infection describe what happens to a susceptible host once a pathogen invades the human body. The stages of infection are incubation, prodromal, illness, stage of decline, and convalescence. The incubation stage is the period from exposure to a pathogen until symptoms start. The infected person is unaware of impending illness as the pathogens grow and multiply within the body. The duration may vary depending on the type of infection. The incubation period of measles averages ten to...

01:20Frustration and Conflict: Approach-Approach, Approach-Avoidance

Frustration occurs when people are obstructed or prevented from achieving a desired goal or fulfilling a perceived need. For example, when someone's input is ignored in a discussion, it can lead to feelings of frustration. Conflict, however, arises from opposing interests, goals, or actions. Conflicts can take various forms based on the nature of these opposing desires or goals.
One common type of conflict is the Approach–Approach Conflict. In this case, a person faces two desirable...

01:16Psychosexual Stages of Personality: Latency
1.2K
Following the phallic stage in Freud's theory of psychosexual development, children enter a phase called the latency period, which lasts from approximately six to twelve years of age. Unlike earlier stages, where sexual impulses played a central role, Freud believed these impulses are repressed during the latency period, becoming part of the unconscious. This stage is often described as a time of psychological calm after the turbulence of the phallic stage.

1.8K
The genital stage is the final phase of Sigmund Freud's theory of psychosexual development, beginning at puberty, around age 12. During this stage, sexual energy shifts from self-focused interests to external individuals, marking the development of mature adult sexuality. Freud saw this phase as a time of sexual reawakening, with desires directed toward others outside the family. A healthy transition into this stage, according to Freud, signifies the emergence of two key aspects of adult...
