“…Human papilloma virus (HPV) was identified as a causal agent of cervical cancer by zur Hausen and colleagues in 1983 1 and more recently, oncogenic HPV types (mainly 16, 18, 31 and 45) have been found to be associated with head and neck, anal and penile squamous cell carcinomas (SCC). 2 The association of HPV with oral cavity and oropharyngeal cancer (OC and OPC) was first reported by Löning et al 3 and de Villiers et al 4 in 1985. We now know that HPV is mainly associated with OPCs ( Fig.…”

“…3 This is equally relevant to surgeons and emergency medicine trainees performing primary or secondary surveys of the trauma patients. 4 In areas of cosmetic significance, magnification increases confidence to use finer suture materials and makes tissue manipulation less traumatic. In plastic surgery and dermatology outpatient clinics, magnification is a valuable adjunct in the evaluation of skin conditions (dermatoscopy being very much in vogue).…”

Loupes are commonly used when high demands of visual performance are needed. This article will review the available information on who should use loupes, and provide a guide on when and how to use them. Purchasing this piece of equipment should not yield to a pressure to be 'equipped' for certain procedures, nor should it copy other surgeon's choices blindly. 1 Magnification has revolutionized the operating theatre. Even for macroscopic procedures, it allows appreciation of subtle tissue differences, permits a sharper navigation within the anatomical borders and a more precise instrument positioning.According to Professor WA Morrison, 'using the microscope is not essentially different from turning on the theatre lights; if you can see what you are doing, you have a better chance of doing it well'. 2 The use of magnification dramatically improves wound care, allowing precise debridement and clear identification of anatomical structures and foreign bodies. 3 This is equally relevant to surgeons and emergency medicine trainees performing primary or secondary PERSPECTIVES ANZJSurg.com

“…The Galilean system has concave lenses, keeps the light rays at the top of the image in the correct orientation, and produces a direct image, thus providing greater depth of field. The Keplerian system has convex lenses and produces an inverted image that must be rotated by an internal system of prisms, a process which increases the field of vision and produces greater magnification [ 10 ].…”

Magnification effect on fine motor skills of dental students

et al. 2021

Objectives This study observed the effect of different magnification systems on dental students’ real and perceived fine motor skills. Methods This was a laboratory-based experimental study. Students in the fifth year of an undergraduate dentistry program (N = 92) participated in this study. The dependent variables were real motor skills, perceived motor skills and time required to complete the fine motor skills test. The independent variable was the use of a magnification system under four conditions. For each condition, the Dental Manual Dexterity Assessment was performed, which consisted of inserting the #3195FF bur into targets positioned on a Styrofoam plate. The accuracy of each penetration of the targets was scored, using a point system with a maximum possible score of 246 points. Students’ perceived fine motor skills were assessed using a visual analog scale (VAS) that ranged from zero for no skills to ten for maximum skills. A descriptive statistical analysis and the repeated measures ANOVA were performed (α = 0.05). Results The Galilean and Keplerian loupes were found to positively affect students’ real fine motor skills (p<0.01); however, perceived fine motor skills and time were significantly better (p<0.01) under the naked eye. Conclusions Dental students’ real fine motor skills were better when Galilean and Keplerian loupes were used, but the perceived fine motor skills were not.
