Voice disorders can sometimes be a polyp, which can be diagnosed during an endoscopic examination, or they can have a very complex etiology. Therefore, a competent and technologically equipped sound laboratory and clinicians with the ability and experience to interpret the information obtained in this laboratory and make the final diagnosis is an important factor in making the diagnosis. In addition to the “videolaryngostroboscopy” devices that we use for different purposes in our clinic, there are special analysis programs that we perform sound analysis in digital environment. In addition, objective and subjective evaluations of the professional voice are made in our sound studio, which is part of our clinic.
