Correlations between videoendoscopy and sonotubometry of eustachian tube opening during a swallow.
OBJECTIVES/HYPOTHESIS Describe the relationship between the magnitude of eustachian tube (ET) dilation during swallowing observed on transnasal videoendoscopy and quantified by sonotubometry. STUDY DESIGN Descriptive observational study. METHODS Simultaneous transnasal videoendoscopic and sonotubometric recordings were done on 33 adults with no middle ear disease. Briefly, microphones were ...

OBJECTIVE To determine the role played by the tensor veli palatini and levator veli palatini muscles (mTVP and mLVP, respectively) in eustachian tube (ET) opening. DESIGN Prospective study. SETTING Research laboratories at a tertiary care hospital. PATIENTS Fifteen healthy adults with normal middle ears and documented ET openings. INTERVENTIONS Submental and ground surface electrodes we...
متن کاملEustachian Tube Opening Measurement by Sonotubometry Using Perfect Sequences for Healthy Adults
OBJECTIVES The aim of this study was to establish the rate variation of sonotubometric measurements using a specific broadband class of signals, the so-called perfect sequences (PSEQ) among healthy adults and to identify an optimal and technically simple test to provoke Eustachian tube (ET) openings. METHODS Sonotubometry was performed on 105 healthy adult subjects. Three different consecutiv...
متن کاملQuantitative description of eustachian tube movements during swallowing as visualized by transnasal videoendoscopy.
IMPORTANCE Eustachian tube (ET) dysfunction predisposes ears to otitis media, tympanic membrane retraction, retraction pocket and perforation, or cholesteatoma. OBJECTIVE To develop a method to quantitatively measure the eustachian tube (ET) component movements and their interactions captured by transnasal videoendoscopy of the ET during swallowing. DESIGN, SETTING, AND PARTICIPANTS A blind...
متن کاملSonotubometry: a useful tool to measure intra-individual changes in eustachian tube ventilatory function.
OBJECTIVE To determine whether intra-individual changes in eustachian tube (ET) function induced by local application of a histamine phosphate solution can be detected using an improved sonotubometer. DESIGN The function of the ET was measured with a revised sonotubometer before and after histamine was applied to the nasopharyngeal ostium of the ET. SETTING Tertiary referral hospital. PAT...
