Our hypothesis was that as a result of its improved
glottic vision; the McGrath VL would reduce the time taken to intubate patients undergoing cesarean section.
Many studies have evaluated the best approach to management of early
glottic cancers.
Furthermore, the intubation time, the number of intubation attempts, need for stylette or additional manipulation,
glottic view (Cormack--Lehane) and traumatic complications caused by intubation procedure were recorded as secondary outcomes.
Treatment depends on the degree of airway obstruction at the
glottic level.
The main purpose of conservative laryngeal surgery for
glottic carcinoma is to provide local control by maintaining laryngeal function.
It allows characterizing the
glottic source regarding its muscular and muco-undulatory functioning and its vocal quality, seeing that some alterations are better observed in the sustained emission of isolated phonemes [6,8,16].
If the protuberance is an appropriate point for the suture placement, a 21# needle will be introduced into the
glottic lumen and the 2# nylon stitch will be carried through the needle canal, and then into the lumen.
Stroboscopy will show stiff vocal folds, a reduced mucosal wave, poor vibratory function of the vocal fold, and
glottic insufficiency.
Regarding the location of the tumor, the
glottic region (208 patients, 50.1%), the supraglottic region (113 patients, 27.2%), the subglottic region (13 patients, 3.1%), and more than one region (81 patients, 19.5%) of the patients were involved.
The types of the
glottic stenosis developed in the patients are presented in Figure 13.
The surgeons anticipated that the
glottic and subglottic granulation tissue may cause bleeding or airway obstruction.
