An ENT specialist asks detailed questions about the signs and symptoms being faced by the patient and then examines him or her thoroughly. To examine vocal cords, an instrument like a laryngoscope may be used. Sound analysis and laryngeal electromyography are some of the additional tests that can be conducted in order to check the irregularities in the sound generated by the vocal cords.
After the correct diagnosis, the treatment is then decided based on the report and nature and extent of the problem being faced. Micro laryngeal surgery is a minimally invasive medical procedure that eradicates the abnormal growths in the vocal cords, thereby treating the vocal disorder. It is performed under general anesthesia. The damaged tissues are excised with utmost precision by using a laryngoscope, a thin metal tube with an endoscope at its end.
