ABSTRACT: The Phoniatric Unit, Ain Shams University, Cairo, started to use a leading protocol for the assessment of velopharyngeal incompetence (VPI) in 1995. It comprised three levels according to the complexity of the tools used. The first level consists of elementary diagnostic procedures. They are rather simple and non-invasive but essentially subjective. Despite the clinical feasibility of these procedures, an attempt to objectify the data is made utilizing the tools on the second level of assessment, namely, the clinical diagnostic aids. This level comprises video-nasofibroscopy, roentgenological methods and high fidelity audio recording of speech. The third level of assessment, namely, additional instrumental measures, uses a more sophisticated armamentarium of research tools in an attempt to quantify the qualitative, quasi-objective measures deduced from nasofibroscopy. It comprises of many parameters including acoustic nasometry, aerodynamic studies and others.
