Research Paper: Surgical Options for Post-Larengectomy

This is a research paper on surgical options for post-larengectomy. When the tracheotomy is close up (with the patients thumb or a stoma valve) expiratory blood line is redirected to vibrate the muscles of the pharyngo-oesophageal anatomical sphincter to release an alaryngeal articulatio.\n\n\nExplain TEP speech and how the voice prosthesis works\n\nWhen the tracheotomy is occluded (with the patients thumb or a stoma valve) expiratory air is redirected to vibrate the muscles of the pharyngo-oesophageal sphincter to produce an alaryngeal voice. The vibrating sound travels without delay into the oral cavity, where it is shaped by the articulators into speech sounds. A unidirectional air valve of appropriate coat and diameter is inserted to maintain the obviousness of the tracheo-oesophageal fistula. A duckbill or trapdoor arrangement at the distal (oesophageal) end of the valve prevents food entranceway the trachea via the valve. (Carding, 2001, p 298)\n\nAdvantages of TE P\n\nThe tracheoesophageai-esophageal bypass (TES) technique (Amatsu, 1978, 1980) enables the patient to engage air from the trachea. This can be accomplished by connecting the trachea and the upper part of the esophagus. This surgical technique appears to offer a better voice select (Johns & Cantrell, 1981; Wetmore, Krueger, & Wesson, 1981) and a general listener preference (Clark & Stempie, 1982) than the traditional esophageal voice. In addition, acoustic compendium has suggested that the TES voice is more pictorial and exhibits more stability in fundamental frequency than esophageal voice (Robbins, 1984; Rob-bins et al., 1984). Doyle et al. (1988) compared patients with TES and esophageal patients victimisation nonsense stimuli. The parameters analyzed were boilers suit consonant intelligibility, voicing, manner, and consonant omissions.\n\n companionable order custom do Essays, Term Papers, Research Papers, Thesis, Dissertation, Assignment, platter Reports, Reviews, P resentations, Projects, Case Studies, Coursework, Homework, Creative Writing, diminutive Thinking, on the topic by clicking on the order page.If you take to get a full essay, order it on our website:
