AI Article Synopsis

  • This study aimed to compare three cephalometric analyses (Steiner, McNamara, and Ricketts) and their relationship with airway volume using 2D and 3D imaging in patients requiring jaw surgery.
  • The research found significant differences between the analyses in measuring the maxilla and mandible positions, with notable airway volume differences identified between skeletal classes II and III patients.
  • The conclusion suggests that class II skeletal patients generally have smaller airway volumes than class III, although the relationship between skeletal parameters and airway volume isn't always straightforward.

Article Abstract

Objective: The aim of this research was to compare three cephalometric analyses and their correlation with the airway volume in subjects with different skeletal classes using 2D and 3D images. . Cross-sectional descriptive study. . Steiner, McNamara, and Ricketts analyses and the airway volume were compared in 115 subjects who were candidates for orthognathic surgery under diagnosis using cone beam computed tomography (CBCT); 46 males (40%) and 69 females (60%) were included. The sagittal positions of the maxilla and mandible, the angulation of the mandibular plane, the sagittal positions of the upper and lower incisors, measurements of the largest or shortest airway area, and the volume were compared using Spearman's test considering a value < 0.05.

Results: Differences were observed between the Steiner and McNamara techniques for the sagittal position of the maxilla ( = 0.01). For mandibular angulation, there was a greater difference between values for Steiner and Ricketts techniques ( = 0.001). In the upper incisor, the results for McNamara and Ricketts techniques were significantly different ( = 0.004). Analysing the airway, subjects with a class II skeletal pattern had a smaller volume than those with a class III pattern ( = 0.034).

Conclusion: It may be concluded that skeletal class II patients have a significantly smaller airway volume than class III patients. The skeletal parameter does not always relate to the airway volume; however, the high mandibular angle could be related to the airway conditions.

Increased plasma interleukin-1β is associated with accelerated lung function decline in non-smokers.

Pulmonology

Interleukin-1β is one of the major cytokines involved in the initiation and persistence of airway inflammation in chronic obstructive pulmonary disease (COPD). However, the association between plasma interleukin-1β and lung function decline remains unclear. We aimed to explore the association between plasma interleukin-1β and lung function decline.

Introduction: As airway liquid is cleared into lung interstitial tissue after birth, the chest wall must expand to accommodate this liquid and the incoming air. We examined the effect of applying external positive and negative pressures to the chest wall on lung aeration in near-term rabbit kittens at risk of developing respiratory distress.

Methods: Rabbit kittens (30 days; term ∼31 days) were randomised into and groups.

Comparing spirometry, impulse oscillometry with computed tomography for assessing small airway dysfunction in subjects with and without chronic obstructive pulmonary disease.

BMC Pulm Med

January 2025

State Key Laboratory of Respiratory Disease & National Clinical Research Center for Respiratory Disease & National Center for Respiratory Medicine & Guangzhou Institute of Respiratory Health, The First Affiliated Hospital of Guangzhou Medical University, Guangzhou, 510120, China.

Background: Studies on consistency among spirometry, impulse oscillometry (IOS), and histology for detecting small airway dysfunction (SAD) remain scarce. Considering invasiveness of lung histopathology, we aimed to compare spirometry and IOS with chest computed tomography (CT) for SAD detection, and evaluate clinical characteristics of subjects with SAD assessed by these three techniques.

Methods: We collected baseline data from the Early COPD (ECOPD) study.

Aim: This study aimed to analyze the upper airway dimensions in adult patients with different anteroposterior (sagittal) skeletal malocclusions (class I, II, and III) using cone beam computed tomography (CBCT) imaging.

Materials And Methods: This retrospective cross-sectional study involved 90 CBCT records from adult subjects who were categorized into three skeletal groups based on their ANB values: Class I ( = 30), class II ( = 30), and class III ( = 30) and were evaluated. The following upper airway measurements were considered: oropharyngeal airway volume, hypopharyngeal airway volume, pharyngeal airway volume, oropharyngeal airway length, hypopharyngeal airway length, pharyngeal airway length, the most constricted site of the pharyngeal airway, and the most constricted cross-sectional area (MIN-CSA) of the pharyngeal airway.

Aim: The current study aimed to assess the oropharyngeal space using cone-beam computed tomography (CBCT) and its effect on airway volume both before and after denture placement.

Materials And Methods: For this investigation, a total of 15 individuals with fully edentulous upper and lower ridges, ranging in age from 40 to 70, were taken into consideration. A recording of the pulmonary function test was made both prior to and following full denture recovery.
