Nose and Nasal Cavity01:24

Nose and Nasal Cavity

11.4K
The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...

Administering Oxygen by Nasal Cannula01:29

Administering Oxygen by Nasal Cannula

3.0K
Oxygen therapy is critical to patient care, especially for those struggling with respiratory issues. This intervention increases the oxygen concentration in the lungs, enhancing the amount of oxygen transported to the body's tissues. One standard method of delivering supplemental oxygen is through a nasal cannula, a non-invasive device that provides low to medium oxygen concentrations.

A nasal cannula is a lightweight tube split into two prongs placed in the nostrils,...

Oxygen Delivering System I: Nasal Cannula and Face Mask

1.6K
The human body requires oxygen to function, and when the natural process of respiration is hindered, external devices, including the following, are needed to help deliver this vital gas.
Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.
Oxygen percentage setting:...

Assembly of Complex Microtubule Structures01:32

Assembly of Complex Microtubule Structures

2.5K
Complex microtubule structures are present in resting cells and in dividing cells. In resting cells, they are responsible for maintaining the cellular architecture, tracks for intracellular transport, positioning of organelles, assembly of cilia and flagella. They mediate the bipolar spindle assembly for chromosomal segregation and positioning of the cell division plate in dividing cells. The formation of microtubule complex structures depends on the cell type, cell stage, and cell function.

Binet's Contribution to Measures of Intelligence01:23

Binet's Contribution to Measures of Intelligence

1.7K
Alfred Binet, along with his student Théophile Simon, was tasked by the French Ministry of Education in 1904 to create a method for identifying students who struggled to learn through conventional classroom instruction. This initiative aimed to address overcrowding by placing such students in specialized schools. Binet and Simon developed an intelligence test comprising 30 tasks, ranging from simple commands, like touching one's nose or ear, to more complex tasks, such as drawing...

Wechsler's Contribution to Measures of Intelligence

2.1K
David Wechsler, a psychologist who worked with World War I veterans, developed a significant IQ test in 1939 called the Wechsler-Bellevue Intelligence Scale. This test was innovative because it combined several subtests that measured both verbal and nonverbal skills, reflecting Wechsler's belief that intelligence is a global capacity involving purposeful action, rational thinking, and effective interaction with the environment. This test later evolved into the Wechsler Adult Intelligence...

Summary
This summary is machine-generated.

Persistent nasal obstruction after surgery may be linked to narrow, high palates. Skeletal remodeling, like maxillary expansion, might help these patients achieve better breathing.

Area of Science:

  • Otolaryngology
  • Rhinology
  • Skeletal Morphology

Background:

  • Nasal obstruction significantly impacts quality of life.
  • Previous intranasal surgeries (e.g., endoscopic sinus surgery, septoplasty) may not resolve nasal obstruction in all patients.
  • The role of hard palate and nasal floor morphology in persistent obstruction requires further investigation.

Purpose of the Study:

  • To evaluate the contribution of nasal floor and hard palate morphology to persistent nasal obstruction in patients who did not respond to prior intranasal surgery.
  • To identify specific skeletal characteristics associated with treatment failure after nasal surgery.

Main Methods:

  • Retrospective case-control study involving 89 patients with nasal obstruction (52 experimental, 37 control) and 575 initial cohort.
  • Computed tomography (CT) scans analyzed by blinded experts for nasal airway and hard palate morphology.
  • Key measurements included anterior nasal floor width, maxillary angle, maxillary width, and palatal vault height.

Main Results:

  • Significant associations were found between persistent nasal obstruction and specific skeletal features.
  • Acute maxillary angle (P = .035), narrow maxillary width (P = .006), and a high arched palate (P = .004) were linked to persistent obstruction.
  • These findings highlight the influence of craniofacial structure on surgical outcomes.

Conclusions:

  • Narrow and high arched hard palates can contribute to persistent nasal obstruction, even after surgical intervention.
  • Patients with these morphological traits may not achieve adequate nasal airflow with standard intranasal procedures alone.
  • Consideration of skeletal remodeling procedures, such as maxillary expansion, may be beneficial for select patients with persistent nasal obstruction.
