Nasopharyngeal Carcinoma (NPC) is a highly happening disease. Eustachain tube atrisia after radiotherapy is easy to occur in NPC patients. This study presented 2 cases of re-opening of Eustschian tube atresia after radiotherapy for NPC patients. Two female cases (62 and 64 y old; receiving postradiothapy 6 and 20 y ago, respectively) were diagnosed with Eustachian tube pharyngeal orifice atrisi...

BACKGROUND The purpose of this retrospective study was to determine the long-term effects of radiotherapy on hearing function in patients who underwent parotidectomy and postoperative radiotherapy for unilateral tumors of the parotid gland. METHODS An extensive set of tests was used to measure hearing loss. The mean dose on middle ear, cochlea, and Eustachian tube was estimated with a CT-plan...

BACKGROUND Chronic otitis media with effusion is a persistent complication essentially universal in children with cleft palate. The prevalence of chronic otitis media with effusion is hypothesized to be a result of Eustachian tube dysfunction secondary to the anomalous insertion of the palatal musculature. This study was designed to evaluate the timing of tympanostomy tube placement and the eff...

At the present time, the function of the TTM remains unknown. One of the main hypotheses accredited in the literature interprets the TTM, together with the Tensor Veli Palatini (TVP), as part of the same anatomic unit [1]. There is an evident phylogenetic connection with respect to the innervation, irrigation and formation of the structures of the throat and ear, including the Eustachian tube. ...

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...

The inability to open the collapsible Eustachian tube (ET) has been related to the development of chronic otitis media. Although ET dysfunction may be due to anatomic and/or mechanical abnormalities, the precise mechanisms by which these structural properties alter ET opening phenomena have not been investigated. Previous investigations could only speculate on how these structural properties in...
