Sutures of the Skull01:22

Sutures of the Skull

13.3K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

Frustration and Conflict: Approach-Approach, Approach-Avoidance

553
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...

Actuarial Approach01:20

Actuarial Approach

324
The actuarial approach, a statistical method originally developed for life insurance risk assessment, is widely used to calculate survival rates in clinical and population studies. This method accounts for participants lost to follow-up or those who die from causes unrelated to the study, ensuring a more accurate representation of survival probabilities.
Consider the example of a high-risk surgical procedure with significant early-stage mortality. A two-year clinical study is conducted,...

Information Processing Approach01:30

Information Processing Approach

610
The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is...

The Nativist Approach01:21

The Nativist Approach

482
The nativist approach to infant cognitive development proposes that infants are born with inherent knowledge structures that allow them to interpret the world almost immediately. This perspective contrasts with earlier developmental theories, such as those proposed by Jean Piaget, which emphasized a more gradual acquisition of cognitive abilities through interaction with the environment. One key concept in this approach is object permanence — the understanding that objects continue to...

Kaplan-Meier Approach01:24

Kaplan-Meier Approach

632
The Kaplan-Meier estimator is a non-parametric method used to estimate the survival function from time-to-event data. In medical research, it is frequently employed to measure the proportion of patients surviving for a certain period after treatment. This estimator is fundamental in analyzing time-to-event data, making it indispensable in clinical trials, epidemiological studies, and reliability engineering. By estimating survival probabilities, researchers can evaluate treatment effectiveness,...

Summary
This summary is machine-generated.

Endonasal suture techniques offer a viable alternative for nasal tip plasty, proving effective for primary and revision cases. While technically demanding, this approach reduces operating time and speeds patient recovery.

Area of Science:

  • Plastic Surgery
  • Otolaryngology

Context:

  • The external approach is increasingly favored for rhinoplasty.
  • Endonasal techniques are versatile for nasal tip deformities.

Purpose:

  • To review endonasal techniques for nasal tip plasty.
  • To evaluate their efficacy in primary and revision cases.

Summary:

  • Endonasal approaches were used in 81% of 100 rhinoplasties.
  • Sutures repositioned alar cartilages and columella, often without grafts.
  • Preferred incisions included infracartilaginous and transfixion approaches.

Impact:

  • Endonasal suture techniques are technically challenging but offer shorter operating times and faster recovery.
  • These techniques can replace the external approach and grafts in many cases.
  • Endonasal tip plasty should be part of a rhino-surgeon's skill set.
