Objective:
The objective of this study was to undertake a multidimensional assessment of female tracheoesophageal prosthetic speech.
Study Design:
A cross-sectional cohort study.
Setting:
Head and Neck Unit in a tertiary oncology referral centre.
Patients:
Ten female and 10 male total laryngectomy patients with no signs of recurrence and using voice prosthesis were compared to 10 normal female speakers.
Intervention(S):
Electroglottographic and acoustic analysis of voice parameters for both sustained vowel /i/ and connected speech, perceptual evaluation using GRBAS (with 2 experienced raters) and questionnaire assessment using the University of Washington Quality of Life and the Voice Handicap Index. Statistical analysis was done using the Statistical Package for Social Sciences, (v. 14, SPSS Inc., Chicago III).
Results:
Median age of the female larygectomy patients was 65 years (range: 41-81), that of male laryngectomees was 66.5 years (range: 40-79) and that of the normal female subjects was 47.5 years (range: 35-72). All electroglottographic, acoustic parameters and GRBAS ratings of the female laryngectomy patients were significantly worse as compared with the normal female subjects. The median fundamental frequency (111.8 Hz) was comparable to male tracheoesophageal speakers (115.8 Hz). Mean composite University of Washington Quality of Life score and overall Voice Handicap Index score was 79.3(12.5) and 47.5(27.6) for the female laryngectomy patients and for the males was 81.2 (9.6) and 39.4(18.7).
Conclusions:
Gender frequency differences as seen in normal subjects are lost following a laryngectomy operation as evidenced by electroglottographic and perceptual data. Although the quality of life scores are comparable to the male tracheoesophageal speakers, they exhibit a greater voice handicap as compared to their male counterparts.

01:29Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
