[Most frequent errors in diagnosis and treatment of vocal dysfunction]
Abstract:
Vocal disturbances can be a symptom as laryngeal diseases, and a primary clinical manifestation of an endocrine, neurological or systemic disease, tumors located in the base of the skull, neck, chest. Main causes of the misdiagnosis of vocal disturbances lie in misinterpretation of the results of acoustic study of voice, incomplete case history and inadequately made laryngoscopy. Efficacy of vocal disturbance treatment depends on staged, etiopathogenetic approach with consideration of individual features of the patient. Patients with recurrent and lingering laryngeal diseases should be referred to specialized clinics.

Types of Errors: Detection and Minimization
Absolute error in a measurement is the numerical difference from the true or central value. Relative error is the ratio between absolute error and the true or central value, expressed as a percentage.
Errors can be classified by source, magnitude, and sign. There are three types of errors: systematic, random, and gross.
