SVL revealed new lesions on the posterior third of each musculomembranous
vocal fold that appeared inflammatory (figure 5, A).
It is musculomembranous
in nature (Jabbar, 2014), acts as prehensile organ and helps in taking food, mastication, swallowing and rumination.
Tracheal diverticulosis due to protrusion of remnants of the musculomembranous
tissue in between the cartilage rings can cause a corrugated or scalloped appearance of trachea as seen in our case.
Strobovideoscopy shows the paresis podule (pseudocyst) on the left musculomembranous
Strobovideolaryngoscopy revealed an anterior glottic web involving half of the musculomembranous
The vibratory function of both musculomembranous
vocal folds was decreased.
Mucosal tears occur at points of maximum shear force, which are almost always located in the middle of the musculomembranous
portion of the vocal fold in the striking zone.
Postoperatively, an area of stiffness remained in the middle of the musculomembranous
vocal fold, and although a vocal fold hemorrhage had resolved, venous lakes that had been present prior to surgery were unchanged (figure).
The ridges made contact anteriorly and led to the failure of glottic closure in the anterior, middle, and posterior segments of the musculomembranous
Strobovideolaryngoscopy revealed the presence of a broad-based sessile polyp that was centered in the striking zone and which occupied more than one-third of the right musculomembranous
vocal fold (figure 1).
There was diffuse stiffness at its base that resulted in a moderately decreased mucosal wave amplitude and waveform in the middle and posterior thirds of the musculomembranous
 The anterior glottis (or phonatory glottis or membranous glottis) is formed by the musculomembranous
part of the vocal folds, which vibrate during phonation.
