Sizing device used to measure the depth of tracheoesophageal wall and determine appropriate prosthesis length. Comparison photos of an aspirated indwelling style prosthesis on chest x-ray vs CT scan. Only the outside ring of the esophageal flange is radiopaque. Insertion of a low-pressure prosthesis with gelatin capsule. Top photo shows leakage of ingested liquids around the device, which indicates an expanding tracheoesophageal tract possibly due to a prosthesis that is too long.
Bottom photo shows indwelling style prosthesis in place.
An objective method for prediction of tracheoesophageal speech production. An endoscopic technique for restoration of voice after laryngectomy. A comparison of the speech acceptability of good and excellent esophageal and tracheoesophageal speakers. Medicine is a constantly changing science and not all therapies are clearly established. New research changes drug and treatment therapies daily.
