Presentation transcript:

Diagnosis of dysphonia: I.History taking. II.Physical examination: APA, …, neck, … III.Investigations: - Audio recording. - Digital laryngostroboscopy. - Digital laryngokymography. - Acoustic analysis (MDVP). - Aerodynamic analysis (Aerophone II). - GERD (LPR) work-up. - CT neck. *Voice SheetVoice Sheet

Auditory Perceptual Analysis (APA): 1. Overall grade: normal, slight, moderate, severe. 2. Character (quality): strained, leaky, breathy, rough. 3. Pitch: increased, decreased, diplophonia, normal for age. 4. Register: - habitual register: modal, falsetto, vocal fry. - register break. 5. Loudness: loud, soft, fluctuation, normal. 6. Glottal attack: hard, soft, normal. 7. Associated laryngeal functions: cough, whisper, laughter.

Stroboscopic examination: 1- Glottic closure: complete, incomplete (shape). 2- Glottic gap: site, size. 3- Glottic wave: great, normal, small, absent. 4- Amplitude: great, normal, small, zero. 5- Symmetry: in phase, in amplitude. 6- Phase closure: open phase predominate, close phase predominate. 7- Stroboscopic fixation. 8- Additional morphological findings.

Videolaryngokymography: - Symmetry (both sides) in: # Amplitude. # Mucosal wave. # Phase. - Periodicity (same side) in:. Amplitude.. Glottal cycle timing. - Closed phase.
