Quantitative 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 کاملEndoscopic transnasal shim technique for treatment of patulous Eustachian tube.
INTRODUCTION An abnormally patent Eustachian tube, known as a patulous Eustachian tube (pET), can cause disabling autophony as well as annoying transmitted sounds of breathing and swallowing. The elegant work of Poe’s group has shown that the anatomical defect is found in the anterolateral tubal valve of the nasopharyngeal end of the Eustachian tube (ET). To the frustration of both patients and...
متن کاملCorrelations 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 ...
متن کاملRelationship between the electromyographic activity of the paratubal muscles and eustachian tube opening assessed by sonotubometry and videoendoscopy.
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 کاملUpdate on eustachian tube dysfunction and the patulous eustachian tube.
PURPOSE OF REVIEW The purpose of this review is to summarize the recent knowledge on eustachian tube dysfunction and the patulous eustachian tube. RECENT FINDINGS A clinically useful test for eustachian tube function is still lacking. Narrowing of the isthmus alone was demonstrated to be an insufficient cause of otitis media. Inflammatory mediators identified within the eustachian tube and mi...
