Vocal fold polyps can disrupt vocal fold dynamics and thus can have devastating consequences on a patient's ability to communicate. Three-dimensional flow separation induced by a wall-mounted model polyp and its impact on the wall pressure loading are examined using particle image velocimetry, skin friction line visualization, and wall pressure measurements.

Rotary Evaporation to Remove Solvent

Source: Dr. Melanie Pribisko Yen and Grace Tang — California Institute of Technology Rotary evaporation is a technique most commonly used in organic chemistry to remove a solvent from a higher-boiling point compound of interest. The rotary evaporator, or "rotovap", was invented in 1950 by the chemist Lyman C. Craig. The primary use of a rotovap is to dry and purify samples for downstream applications. Its speed and ability to handle large volumes of solvent make rotary evaporation a preferred...

FAQs
Histopathological examination determines the polyp’s tissue type after removal. The recovered specimen is assessed microscopically rather than relying only on its appearance during endoscopy. This result helps clinicians decide what follow-up is appropriate and supports evaluation of potential health risks, making tissue analysis a key part of the clinical process.
Endoscopic treatment may use biopsy forceps or a wire snare to remove the targeted polyp. These instruments provide the means of tissue removal, while cautery is an additional measure that may be needed for larger lesions to control bleeding. The recovered tissue is then retained for histopathological examination.
Cautery may be added when a lesion is larger to help control bleeding during the procedure. Its role is therefore procedural rather than diagnostic: the removed tissue still requires histopathological examination to identify its type. This distinction separates immediate treatment support from the later assessment that guides clinical follow-up.
During endoscopic treatment, the clinician guides an instrument to the polyp, removes it with biopsy forceps or a wire snare, and recovers the specimen. If the lesion is larger, cautery may be used to control bleeding. The tissue then undergoes histopathological examination, linking intervention with diagnostic evaluation.
In colorectal screening, removing detected polyps serves two purposes within one minimally invasive encounter: it eliminates the identified tissue and supplies a specimen for evaluation. The resulting examination supports early cancer detection and prevention. Thus, the procedure can function as both an intervention and a source of clinically useful diagnostic information.
The clinical value extends beyond physically removing tissue. Polyp removal may relieve symptoms associated with a polyp and help clinicians assess or reduce potential health risks. In colorectal screening, the same intervention also supports early cancer detection and prevention, allowing treatment and tissue evaluation to occur within one care pathway.
