Effect of age and prostheses location on rima glottidis area in equine cadaveric larynges - Zurich Open Repository and Archive


Bischofberger, Andrea S; Hadidane, Ines; Wereszka, Marta; Perkins, Nigel R; Jeffcott, Leo; Dart, Andrew J (2013). Effect of age and prostheses location on rima glottidis area in equine cadaveric larynges. Veterinary Surgery, 42(3):286-290.

Abstract

OBJECTIVE: To determine the effect of horse age and laryngeal prosthesis location on rima glottidis area in cadaveric larynges.
STUDY DESIGN: Experimental study.
ANIMALS: Cadaveric equine larynges (n = 40).
METHODS: Specimens were grouped by age: group 1, ≤5 years (n = 18); group 2, >5 to ≤10 years (n = 12); group 3, >10 years (n = 10). A cranial prosthesis was placed through the dorsal cricoid spine at 70% of the distance of the total cricoid length measured from the caudal rim. A dorsal prosthesis was placed through the caudal rim of the cricoid on the dorsal midline. A lateral prosthesis was placed 1.5 cm lateral to the dorsal prosthesis. All prostheses passed through the muscular process. Rima glottidis area was determined after progressively tightening each suture in 5 N increments from 0 N to 35 N using a tensiometer.
RESULTS: There was no significant effect of age on the area of the rima glottidis at any load for any of the three prosthesis locations.
CONCLUSIONS: Age did not affect the area of the rima glottidis when prostheses were loaded between 5 N and 35 N.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
