The work-up of hoarseness or change in voice quality often requires an experienced team with state-of-the art medical equipments and tools. Among these the most common diagnostic tests and facilities available at the SVC include the following:

1- Laryngeal-Video-endostroboscopy: A test that will allow you to study the behavioral pattern of the vocal fold by converting the fast vibratory movement of the vocal cords into a slow movement, enabling the physician to detect any subtle abnormality in the vocal cords leading to hoarseness.

2- Fiberoptic nasopharngoscopy and laryngoscopy: A test that will allow you to examine all the laryngeal and pharyngeal anatomy and biomechanical properties.

3- Acoustic acoustic analysis: A test that extracts objectively the salient features of speech and vocal signal.

4- Upper airflow measures: This test measures the subglottic pressure, mean flow rate, peak expiratory flow, glottal efficiency, and other parameters. The usefulness is mainly in patients with obstructive lesions of the upper airway and need surgical intervention.

5- Pulmonary function test, i.e. spirometry: This test will give us the vital capacity, FEV1 and other parameters. This is of value in measuring the breathing capacity of an individual and in detecting subclinical and clinical asthma, which is often undiagnosed.

6- Audiometry and tympanometry: Test for hearing since many patients with vocal problems, especially singers and musicians have a hearing deficit at a specific frequency.
