Objective: One of the main symptoms occurring in patients with various diseases of the nose and paranasal sinuses which significant deteriorating quality of life is difficult nasal breathing. Dictated by this is a need to develop tools for assessing the geometry of nasal structures. Methods: By analyzing the available literature, the authors make a brief description of working principles and provide main directions for the application of acoustic rhinometry. Results: Due to the acoustic signal generated by a source into one end of the tube of acoustic rinometer, reaching the structures of nasal cavity waves pass through it and make a change in cross-sectional area occur partial reflection of the sound. Reflected waves entering back into the handpiece where they are recorded by a microphone, analyzed by computer system and presented like graphics. Conclusion: Acoustic rhinometry is both minimally invasive and easy carry out study. Fastest realization and absence of discomfort makes it suitable for use in any age.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
