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.

Robert M Rioux, Ajay Sathe, Zhifeng Chen, Pennsylvania State University, University Park, PA A glovebox is an isolated enclosure that is designed to maintain an inert atmosphere. The manipulation of chemicals or apparatus is done via the use of gloves, which allow operation while still maintaining an inert atmosphere. A positive pressure is utilized to compensate for any passive leaks. Objects can be transferred in and out of the box using an antechamber that acts as an airlock between the box...

In this protocol we describe a method of operant learning using sensory stimuli as a reinforcer in the mouse. It requires no prior training or food restriction, and it allows the study of motivated behavior without the use of a pharmacological or natural reinforcer such as food.
FAQs
The speculum helps establish access through the external auditory canal, while the optical system provides illumination and magnification along a maintained line of sight. Together, these components allow the clinician to observe the canal and tympanic membrane while manipulating instruments. This coordinated access is important when a procedure requires both visual control and precise positioning near delicate ear structures.
The working channel permits instruments to pass through the otoscope while the clinician continues viewing the target area. Supported tasks include foreign-body removal, suction, and targeted application of medication. Its main value is coordination: visualization guides instrument movement and helps the clinician perform an intervention at the intended site rather than acting without direct observation.
Direct visualization helps guide topical ear-drug delivery toward the relevant area and allows the clinician to observe treatment-related changes afterward. In pharmacology and clinical practice, this links medication administration with examination findings. The same visual control can also reduce the likelihood of injuring the external auditory canal or tympanic membrane during treatment.
The clinician first uses the speculum and optical system to obtain an illuminated, magnified view of the external auditory canal and tympanic membrane. After establishing a clear line of sight, an instrument can be introduced through the working channel for removal, suction, or medication application. The area can then be observed to evaluate the immediate treatment result.
Clinicians may use it when topical medication must be delivered with visual guidance or when treatment-related changes need assessment. The instrument supports a localized approach by helping identify the area being treated and monitor its appearance. This is especially relevant when accurate placement and protection of the canal or tympanic membrane are important clinical considerations.
Operating otoscopy can show whether a targeted intervention was performed at the intended site and whether the visible ear structures have changed after treatment. It also supports assessment of treatment-related findings in the external auditory canal and at the tympanic membrane. These observations connect the physical examination with decisions about local therapy and follow-up.
