Nasal endoscopy: new tools and technology for accurate assessment.

In this chapter the technique of nasal endoscopy is discussed. Standardized reporting of nasal endoscopy findings is essential in order to allow communication between different surgeons, speech therapists and endoscopists. Representative videos are provided for the normal examination, for coronal and sagittal velopharyngeal closure patterns, as well as for other anatomical variants of interest. Recommendations for tailoring surgical therapy based on the nasopharyngeal closure pattern are given, although the experience of the surgeon is an important factor for success of any surgical procedure for velopharyngeal insufficiency. Limitations and new frontiers of the technique of nasal endoscopy are also outlined.
