Research Paper: Surgical Options for Post-Larengectomy

This is a inquiry paper on functional options for post-larengectomy. When the tracheostomy is occluded (with the endurings hitchhike or a stoma valve) expiratory course is redirected to quaver the muscles of the pharyngo-oesophageal sphincter to bring up an alaryngeal interpreter.\n\n\nExplain TEP expression and how the voice prosthesis works\n\nWhen the tracheotomy is occluded (with the patients pitch or a stoma valve) expiratory air is redirected to flap the muscles of the pharyngo-oesophageal sphincter to take in an alaryngeal voice. The vibrating sound travels in a flash into the oral cavity, where it is mold by the articulators into rescue sounds. A one-way air valve of abstract size and diam is inserted to maintain the noticeability of the tracheo-oesophageal fistula. A duckbill or trapdoor array at the distal (oesophageal) end of the valve prevents viands entering the windpipe via the valve. (Carding, 2001, p 298)\n\nAdvantages of TEP\n\nThe tracheoes ophageai-esophageal beltway (TES) technique (Amatsu, 1978, 1980) enables the patient to use air from the trachea. This can be accomplished by connecting the trachea and the top(prenominal) part of the esophagus. This surgical technique appears to toss a discover voice fictitious character (Johns & Cantrell, 1981; Wetmore, Krueger, & Wesson, 1981) and a ecumenic listener choice (Clark & Stempie, 1982) than the traditional esophageal voice. In addition, acoustic analysis has suggested that the TES voice is more brutal and exhibits more stableness in rudimentary frequency than esophageal voice (Robbins, 1984; Rob-bins et al., 1984). Doyle et al. (1988) compared patients with TES and esophageal patients using nonmeaningful stimuli. The parameters analyzed were boilersuit concordant intelligibility, voicing, manner, and consonant omissions.\n\nKindly rewrite custom make Essays, Term Papers, look Papers, Thesis, Dissertation, Assignment, Book Reports, Reviews, Presentations, Projects, guinea pig Studies, Coursework, H! omework, Creative Writing, vital Thinking, on the question by clicking on the order page.
