We have developed a simple, reliable, and relatively inexpensive method for endotracheal intubation in mice via direct laryngoscopy using an otoscope with a 2.0 mm speculum. This technique is atraumatic and can be used for repeated measurements in chronic experiments. We find it superior to tracheostomy or previously reported nonsurgical techniques.

Source: Richard Glickman-Simon, MD, Assistant Professor, Department of Public Health and Community Medicine, Tufts University School of Medicine, MA The simplest ophthalmoscopes consist of an aperture to look through, a diopter indicator, and a disc for selecting lenses. The ophthalmoscope is primarily used to examine the fundus, or the inner wall of the posterior eye, which consists of the choroid, retina, fovea, macula, optic disc, and retinal vessels (Figure 1). The spherical eyeball...

Source: Jennifer A. Ouellet and Jaideep Talwalkar; Yale School of Medicine To meet the needs of older adults, all health professionals should be well acquainted with the history and physical examination considerations unique to this population. Physical examination plays an important role in the older patient to detect physiologic changes of aging, risk factors, and signs of pathology. While most of the general principles of the standard examination for adults apply to older patients, there are...

Source: Carmen Black, Matthew Goldenberg, and Jaideep Talwalkar; Yale School of Medicine The mental status exam is a clinical evaluation of emotional, perceptual, and cognitive functioning that spans both the fields of psychiatry and neurology. Developing skill in the psychiatric portions of the examination are important to describe salient aspects of the patient's mental state that may be observed during routine history and/or physical exam. Proficiency in the cognitive portions of this...

Pneumatic otoscopy assesses movement rather than relying only on the membrane’s visible appearance. By changing air pressure, the clinician observes tympanic membrane mobility, adding a functional finding to observations of color, position, integrity, and visible fluid. This extra information can strengthen the clinical assessment when standard visual inspection alone does not provide enough detail.
Visual interpretation focuses on several separate membrane features: color, position, integrity, and the presence of visible fluid. Considering these findings together helps the clinician identify abnormalities rather than treating one visual characteristic as conclusive. The external auditory canal is also examined, allowing the assessment to include canal conditions as well as changes in the tympanic membrane.
The otoscope’s light makes the ear structures visible, while the speculum directs that illumination into the area being examined. Magnification then helps reveal membrane features that may not be apparent from unaided viewing, including color, position, integrity, and visible fluid. Together, these components support a more detailed assessment of the canal and tympanic membrane.
The clinician first uses the otoscope to inspect the external auditory canal and tympanic membrane, then records visible characteristics such as color, position, integrity, and fluid. If pneumatic otoscopy is included, mobility is assessed by changing air pressure. These observations are then considered in relation to symptoms and concerns to support clinical decisions.
Clinicians may request an otoscopic exam when a patient has ear pain, hearing concerns, or possible cerumen obstruction. The examination can also support evaluation of otitis externa, otitis media, effusion, or perforation. Because its findings contribute to diagnosis and care decisions, clinicians use it in both primary and specialized clinical settings.
Findings can support diagnosis and help guide treatment decisions, rather than serving only as a visual record. Repeating the assessment can help monitor response to care, while the initial examination may document abnormalities involving the canal or tympanic membrane. This makes the procedure useful for evaluating a current concern and tracking clinical change over time.
