Histopathological Changes in Tracheal Mucosa Following Total Laryngectomy.

The aim of this study was to determine the long term histopathologic changes in tracheal mucosa after a total laryngectomy , and to find out the relationship between the progression of histopathologic changes in tracheal mucosa and the duration of breathing through the tracheostomy. Tracheal mucosal biopsies were taken from a total of 35 patients, of both sexes, who underwent a total laryngectomy for laryngeal carcinoma at least one year prior. Histologic specimens of tracheal mucosa were stained with hematoxylin and eosin and examined under light microscopy.

Pathohistological changes of tracheal epithelium in laryngectomized patients.

Total laryngectomy results in a permanent disconnection of the upper and lower airways. Thus, the upper airways are bypassed and can no longer condition, humidify, and filter the inhaled air, leading to damage of the tracheobronchial epithelium. There is little scientific information available about the effects of tracheostoma breathing and the degree of mucosal damage in laryngectomized patients.

Perceptual evaluation of alaryngeal speech.

The aim of this study was to compare the self-assessed vocal handicap of laryngectomees treated with three different communication methods: tracheoesophageal speech, esophageal speech and electrolarynx. Forty-eight patients, 40 males and 8 females, who had undergone total laryngectomy for laryngeal carcinoma were enrolled in the study. Depending on the voice restoration method, all patients were divided into three groups: 20 patients were tracheoesophageal speakers (group 1), 13 patients were esophageal speakers (group 2) and 15 patients were electrolaryngeal speakers (group 3).

Objective assessment of tracheoesophageal and esophageal speech using acoustic analysis of voice.

The aim of this study was to analyze the voice quality of alaryngeal tracheoesophageal and esophageal speech, and to determine which of them is more similar to laryngeal voice production, and thus more acceptable as a rehabilitation method of laryngectomized persons. Objective voice evaluation was performed on a sample of 20 totally laryngectomized subjects of both sexes, average age 61.3 years.

Epidemiology of laryngeal cancer in Osijek-Baranja County (eastern Croatia).

The aim of this retrospective study was to provide the incidence and mortality rate for all patients with laryngeal carcinoma diagnosed in Osijek-Baranja County, during the period of 1999-2008. In this period, there were 329 registered patients, from which 301 (91.5%) males, and 28 (8.

Importance of correct therapeutic procedure selection in voice recovery.

Psychological and physical patient state as well as the influence of other social factor is of great influence voice rehabilitation. A team of experts in the field of voice and its function are involved in voice therapy. Our research was focused on the successfulness of voice recovery depending on the patient vocal disorder approach.
