“…This is a larger proportion than described earlier 7,[28][29][30] ; only Bremerich et al 31 and M€ akitie et al 32 found similar percentages of patients unable to speak. In contrast, in a survey of all ENT clinics in Germany, the doctors reported that 6.7% of the patients could not speak at all 33 and Jassar et al 34 found in their review that 10% to 15% of all patients do not acquire any voice at all. Possibly our numbers are higher because we performed a relatively strict test where patients had to speak via telephone without having eye contact with the interviewer so the interviewer could not lip read.…”

“…1 In 5% to 15% of the cases, patients do not acquire any voice. 2,3 Frequently, particularly in older publications, acquiring an esophageal voice, in contrast to using a device, is considered a success. [4][5][6] However, for some patients, it is vital to acquire a voice quickly; therefore, an electronic device is an acceptable alternative if it helps in speeding up the rehabilitation process.…”

“…3 Speech is produced by moving the articulators to mouth words in the normal manner. 4 The esophageal voice demonstrates perceptual qualities of harshness, hoarseness, gurgling, short phonation duration and low pitch and volume, 3 all of which are indicators of aperiodicity in voice. Perturbation analysis of this perceptual abnormality has been accomplished, with results confirming the severe irregularity of esophageal voices.…”

Objectives/Hypothesis-Esophageal voice is a method of communication after total laryngectomy. Previous research suggests that perturbation analysis may inaccurately measure aperiodic voices and that nonlinear dynamic methods may be more appropriate for analyzing signals of this type. Therefore, we hypothesized that nonlinear dynamic analysis would be more capable than perturbation parameters for reliable measurement of the aperiodic esophageal voice.Study Design-Acoustic comparison of esophageal and normal voice cohorts using nonlinear dynamic and perturbation measures.Methods-Twenty subjects in two age-matched groups participated in the study. Jitter, shimmer, signal-to-noise ratio, correlation dimension, and second-order entropy were measured from audio recordings of subjects' voices.Results-Jitter and shimmer values were significantly higher for esophageal voices and signalto-noise ratio values were significantly lower for esophageal voices than for normal voices. Error count values, which indicate perturbation analysis reliability, were 0 in normal voices and significantly higher in esophageal voices. Error was attributable to signal aperiodicity and demonstrated that perturbation analysis yielded questionable results for esophageal voice. However, nonlinear dynamics measures analyzed both cohorts reliably and indicated that esophageal voice was significantly more chaotic than normal voice. Conclusions-The results demonstrated the capability of nonlinear dynamic methods to reliably quantify both aperiodic and periodic signals and to differentiate normal from esophageal voices. It is suggested that nonlinear dynamic analysis be used preferentially for acoustic characterization of aperiodic voices such as esophageal voice. Future research should focus on clarification of perturbation analysis reliability and further application of nonlinear dynamic measures to aperiodic voices.

“…Voice loss after total laryngectomy due to laryngeal cancer seems to be the main disadvantage of that surgical procedure for majority of patients [1]. It has been found that in patients, whom a complete removal of the larynx was performed, there is a higher risk of depression in comparison to patients who underwent a different type of treatment and it can result in limited social life [2].…”

a b s t r a c tAim: The aim of the study was to evaluate the effectiveness of a deeply invasive massager Medical 2VR, Cyberbiomed as a supportive voice rehabilitation method in patients after total removal of the larynx. Background: Voice loss after total laryngectomy due to laryngeal cancer seems to be the main disadvantage of that surgical procedure for majority of patients. Neck lymphoedemas, soft tissues fibrosis and restricted mobility around the shoulder girdle due to surgical procedures and radiotherapy are the factors impeding the process of voice rehabilitation. Materials and methods: The study was conducted on a group of 80 patients after total laryngectomy treated in Outpatient Clinic and Department of Otolaryngology of the Medical University of Silesia in Katowice in 2009-2011. Assessment of voice parameters, measurements of neck circumference and pressure in the opening of sphincter of oesophagus mouth were performed. The nature of the emitted voice and speech volume was analyzed. Results: The results showed that in 90% of patients a significant reduction of neck lymphedema was observed. Also, various voice parameters and pressure in the opening of sphincter of oesophagus improved. Conclusions: Invasive massager Medical 2VR results in reduction of the voice rehabilitation period and shorter learning process of substitute speech in patients after total laryngectomy.
