A comparative study of Steiner's and McNamara's cephalometric analyses to determine the position of bone bases was performed in 51 patients and revealed the substantial similarity of the two techniques. The authors consider McNamara's technique to be of greater and more immediate clinical value.

Article Synopsis
- The study aimed to create a new prognostic model to estimate the risk of pulmonary complications after elective surgery, which is the leading cause of post-surgery death.
- Data from a large international cohort of over 86,000 patients was used, applying machine learning techniques to identify risk factors for complications like pneumonia and respiratory distress.
- The model, named the GSU-Pulmonary Score, was validated with additional cohorts and is available as an online tool to assist in patient care and resource management, especially important during pandemic recovery.
Association Between Gender, Age, and Skeletal Class With Mandibular Condyle Morphology: A Retrospective Study.
Cureus
November 2023
School of Stomatology, Clinical Research Laboratory, Autonomous University of San Luis Potosí, San Luis Potosí, MEX.
Objectives: This study aimed to examine the impact of demographic variables on mandibular condyle morphology, a critical factor in orthodontic treatment and maxillofacial surgery. The investigation focuses on the relationship between gender, age, and skeletal class with the morphological dimensions of the condyle, utilizing panoramic radiography as a diagnostic tool.
Methodology: A retrospective analysis was conducted on 150 panoramic radiographs from individuals stratified into six groups according to gender and skeletal class.
Evaluating diagnostic performance of three cephalometric vertical parameters.
Indian J Dent Res
July 2023
Department of Orthodontics, Faculty of Dentistry, Tishk International University-Erbil, Kurdistan Region, Iraq.
Objectives: The goal of this research was to see how reliable and valid three selected parameters from different analysis were in detecting the vertical skeletal pattern.
Methods: There were 94 cephalometric x-rays used in all. The vertical skeletal pattern was assessed using the mandibular plane angle by Steiner, Frankfort mandibular angle by Tweed, and facial axis angle by McNamara.
Background: The 2015 Lancet Commission on global surgery identified surgery and anaesthesia as indispensable parts of holistic health-care systems. However, COVID-19 exposed the fragility of planned surgical services around the world, which have also been neglected in pandemic recovery planning. This study aimed to develop and validate a novel index to support local elective surgical system strengthening and address growing backlogs.

Oral Maxillofac Surg
June 2023
Department of Oral and Maxillofacial Radiology, Post-Graduation Program in Dentistry, Federal University of Ceará, Fortaleza, Ceará, Brazil.
Purpose: This study aimed to analyze alterations in mandibular positioning after surgically assisted maxillary expansion (SARME) with and without pterygoid disjunction (PD).
Methods: Cone-beam computed tomography scans of 24 healthy individuals (18-45 years old) with transverse deficiency, superior to 5 mm, underwent SARME with or without PD. The aspects prospectively assessed were (1) alignment and position of the head (ITK-Snap and 3D Slicer software); (2) McNamara's and Steiner-Tweed-Wits' cephalometric analysis (Dolphin Imaging®); and (3) colorimetric evaluation based on 3D correspondence analysis (3D Slicer software).
