Maximum Phonation Time and Body Mass Index in Nondysphonic Eutrophic Children

Literature presents controversial maximum phonation time values in children. Verify and correlate the maximum phonation time of vowels /a, i, u/ and the body mass index of children. Evaluation of 484 children, eutrophic and without dysphonia, aged from 4:00 to 7:11 years. questionnaire, audiometric screening, auditory-perceptual evaluation of voice, and assessment of the body mass index. measurement of the maximum phonation time of /a, i, u/. Descriptive statistics, t test, and multiple regression at 5% significance. /a:/ = 3.77 seconds at age 4:00 years, 5 seconds at 5:00, 5.85 seconds at 6:00, and 7.5 seconds at 7:00 for boys, and 3.89 seconds, 4.89 seconds, 5.61 seconds, and 6.61 seconds for girls, respectively; /i:/ = 3.49 seconds at age 4:00 years, 4.96 seconds at 5:00, 5.72 seconds at 6:00, and 6.88 seconds at 7:00 for boys, and 3.49 seconds, 4.73 seconds, 5.41 seconds, and 6.63 seconds for girls, respectively; /u:/ = 3.64 seconds at age 4:00 years, 4.85 seconds at 5:00, 5.76 seconds at 6:00, and 7.08 seconds at 7:00 for boys, and 3.54 seconds, 4.73 seconds, 5.64 seconds, and 6.47 seconds for girls, respectively. There were no significant differences between genders, except for /a:/ at age 7:00 years. The correlations were not significant. Maximum phonation time of /a, i, u/ increased with age and its value in seconds was approximately equal to the age in years. At the age 7:00 years, /a:/ from boys was longer. The body mass index did not show influence on the maximum phonation times.

The aim of researches was estimation of quality of voice after operations correcting of the nasal septum deviation. With researches one embraced 40 men in two groups (group I: 20-30 of years old, group II--above 50 of year old). Voice one priced before operation of corrective nose and 6 of months after executed intervention. In researches one used with scale GRBAS, with estimation laryngostroboskopy of function of vocal folds, with acoustic analysis created of voice, with measurement of maximum phonation time and with Polish version of VHI. Patency of nose priced patients at subjective help of five--gradual of scale. After 6 months all ill favourably priced effect executed of operation improving patency of nose. In scale GRBAS in group I examined voice one priced as normal at 12 ill (60%), instead in group II only at 3 men (15%). Above--regularity refers also of roughness of voice. In stroboscope research executed before operation at almost all ill one ascertained diminution of amplitude of twitches of folds vocal and mucosal wave. After 6 months after operation in group I both amplitude of twitches of vocal folds as and mucosal wave at mostly examined surrendered of normalization. In group II profitable changes we observed only at several of persons. Maximum phonation time of vowel "a" after operation of nose surrendered to extension in both groups examined, however men of group I reached significantly better results, with average value approaching to norms. In acoustic analysis to distinct improvement, but only in group I examined surrendered parameter NHR. In estimation with test VHI six months after operation sense of disturbances of voice in both groups surrendered to diminution, in proportion to qualities created of voice. Operating--restoration physiological air passage at all ill causes diminution or liquidation earlier stepping out of disturbances of voice. From passed researches results, that improvement of health, manifesting itself voice euphonious is in considerable percentage possible only at young persons. At ill in middle age and older to entire liquidation of disturbances of voice will reach in single chances.

Ill applying with extensive infiltration of new-growth within of larynx will demand radical therapeutic procedure, which is operation completely removals of organ. Aim of work was estimation of voice and speeches ill with vocal fistula in comparison with oesophageal voice and speech and with physiological. With research one embraced 81 men in age 42-75 of years. Group I--32 ill with cancer of larynx, to which executed total laryngectomy and placed the voice prosthesis Provox 2. Group II--30 ill after operation total removals of larynx, whiches used oesophageal speech. The control group III--19 persons with physiological voice. Research one began from subjective estimation of replacement voices. Then one executed measurements maximum phonation time of vowel "a". To objective estimation of voice one used polish programme "IRIS". One compared: maximum intensities of voices for colloquial speech, F0, Jitter, Shimmer and NHR. In subjective estimation voice of the patients with voice prostheses was greater freedom of production and voice of the patients with voice prostheses appeared to be more loud in relation to oesophageal voice. Greatest statistical essential differences one obtained between maximum phonation times of vowels "a" where clearly is visible, that values obtained for voices of the patients with voice prostheses are to nearer values for physiological voices. Obtained averages values of acoustic analysis: F0, Jitter, Shimmer and NHR did not show statistical of essential differences between voices supplementary, though parameters of voice of the patients with voice prostheses one was to nearer parameters of physiological voice. Characterization perceptive and acoustic speech of the patients with voice prostheses in comparison with oesophageal speech is to nearer characterization of physiological speech. Lack of satisfactory effects of rehabilitation of oesophageal speech, should be effective secondary implantation vocal prosthesis.
