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.

Here, we present a protocol to establish a replicable conductive hearing loss induction via surgical tympanic membrane puncture and verification by otoscope visualization and behavioral assessment by clap startle.
FAQs
Illumination directs light into the canal, while magnification enlarges the observed field. Together, these features help the clinician inspect tissue color, integrity, swelling, fluid, cerumen, and visible lesions more clearly. Better visualization can support evaluation of ear-related symptoms and recognition of findings relevant to diagnosis and care.
The disposable speculum directs illumination into the external ear canal and helps the clinician examine the target area through the instrument. Its use must be paired with gentle insertion and appropriate patient positioning, because these procedural conditions help preserve visualization during assessment of the canal and tympanic membrane.
Comparing both ears provides a reference for interpreting what is seen in the ear being evaluated. The side-to-side approach can improve visualization and help the clinician judge whether observed color, integrity, swelling, fluid, cerumen, or lesions represent a notable finding. This comparison supports more informed diagnosis and follow-up decisions.
It can reveal changes in tissue color or integrity, swelling, fluid, cerumen, and visible lesions. These observations contribute to evaluating conditions specifically identified in the clinical context, including otitis externa, otitis media, foreign bodies, and tympanic membrane perforation. The findings therefore help connect examination results with treatment decisions and subsequent follow-up care.
Begin with appropriate patient positioning, then use a disposable speculum to direct illumination into the canal. Insert the instrument gently and inspect the visible canal and tympanic membrane with magnification. Examining both ears improves visualization and supplies a comparison that can support interpretation of the observed findings.
Otoscopy is useful when ear-related symptoms require visible assessment of the external canal and tympanic membrane. In addition to contributing to identification of otitis externa, otitis media, foreign bodies, or perforation, the examination can guide treatment choices and provide findings for follow-up care. Its value lies in linking direct visualization with clinical decisions.
