Seven dysphonic patients who had previously undergone total or extended cordectomy underwent laryngeal framework medialization. A minimum 6-month period between cordectomy and framework surgery was enforced to allow the vocal cord to scar and form a fibrous "neocord", to evaluate the voice recovery achieved by speech therapy alone and avoid the risk of operating on a patient with undiagnosed early recurrence. The operation is performed with fiberscopic control under general anesthesia. These operating conditions are required because undermining the fibrous tissue at the inner side of the thyroid ala is a lengthy and laborious procedure. This step is necessary to ensure easy placement of the implant. Caution must be taken to avoid tearing the fibrous tissue, with consequent risk of prosthesis extrusion. The cartilage window is left intact. Whereas cartilage implants remain indicated for minor gaps, we advocate Friedrich's implant for wider gaps. The vocal outcome revealed an increased median maximum phonation time from 5 s (range 2-12 s) to 7.5 s (range 3-23 s); a reduced phonation quotient from 516.5 ml/s (range 235-1000 ml/s) to 222 ml/s (range 146-595 ml/s); a slightly increased modal intensity from 61.5 dB (range 57-75 dB) to 67 dB (range 46-68 dB); an improved intensity range from 24.5 dB (range 16-36 dB) to 30 dB (range 16-62 dB); a steady fundamental frequency from 150 Hz (range 132-290) to 152 Hz (range 125-200); and an increased median spectral analysis class from 2 (range 1-3) to 3 (range 2-4). Subjectively, the patients noted that, throughout the day, phonation required less effort and induced less vocal fatigue.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
