Objective: To investigate the clinical value of the seven-item Eustachian Tube Dysfunction Questionnaire(ETDQ-7) in evaluating Eustachian tube dysfunction before and after treatment. Method: A retrospective analysis of 50 patients with Eustachian tube dysfunction diagnosed. All the patients were given chymotrypsin 4 000 IU and dexamethasone injection 5 mg by blowing through the Eustachian tube under nasal endoscopic guidance once daily for 3-6 consecutive days. At the same time, azelastine hydrochloride nasal spray and budesonide nasal spray were applied, 2 sprays each time, 2 times a day; oral Olongma drops, 3 ml each time, 3 times a day...

BACKGROUND: Signs of inflammation are commonly encountered during endoscopic examination of the Eustachian tube (ET) region. The clinical applicability of these findings may be enhanced by use of a standardized assessment score. METHODS: Digital video recordings were obtained of 50 nasal endoscopy examinations of the nasopharyngeal portion of the ET. Four fellowship-trained rhinologists independently reviewed the videos with regard to specific physical findings: edema of the ET torus, erythema of the ET torus, exudate at the ET orifice, and presence of tubal tonsil...

Additionally, the authors review the only 2 similar cases within the literature and describe the common clinical features, radiographic findings, and pathologic characteristics of this exceptionally rare disease process. METHODS: Chart review for single patient, review of literature...

BACKGROUND: Cerebrospinal fluid rhinorrhea from a lateral skull base defect refractory to spontaneous healing and/or conservative management is most commonly managed via open surgery. Approach for repair is dictated by location of the defect, which may require surgical exploration. The final common pathway is the eustachian tube (ET). Endoscopic ET obliteration via endonasal and lateral approaches is under development. Whereas ET anatomy has been studied, surgical landmarks have not been previously described or quantified...

MATERIALS AND METHODS: Retrospective study conducted between 1999 and 2015. The same endonasal endoscopic approach with multiflaps and no stenting was used on 36 children. The flaps were attached with fibrine glue. There were 50% unilateral and 50% bilateral cases, 70% primary and 30% secondary surgery. The mean age at primary surgery for bilateral atresia was 10 days and for unilateral atresia 4 years...

OBJECTIVE: A new combined approach to Eustachian tube dysfunction (ETD) employing new minimally invasive devices is described. STUDY DESIGN: An anatomoclinical classification of ETD was conceived to allow correct categorization of patients and enable comparative studies to be performed. Herein, the authors report on their experience with a consecutive series of obstructive ETD patients treated by balloon dilation of the Eustachian tube using AERA (Acclarent, Menlo Park, CA, USA), combined with a quantic molecular resonance (QMR)-mediated rhinopharyngeal tubal ostial mucosa shrinkage technique with a dedicated "Mitto" hand piece (Telea, Sandrigo-Vicenza, Italy)...

OBJECTIVE: Describes a method of dynamic video-endoscopy of the Eustachian tube (ET) orifice at the nasopharynx to quantitatively represent ET component movements during swallowing using a graphic function and analyze their importance to its opening mechanics. METHODS: This was a pilot study of relational event capture using a polar coordinate system applied to trans-nasal video-endoscopic recordings of the ET during 3 swallows in 5 adults. After topical anesthesia of the nose, a 45° telescope was introduced unilaterally and focused on the ipsilateral ET orifice...

OBJECTIVE: To investigate the correlation of sitting 3-D computed tomography (CT) scans of the Eustachian tube (ET) with subjective and objective findings in patients with patulous Eustachian tube (PET). STUDY DESIGN: Retrospective. SETTING: Tertiary referral center. SUBJECTS: A retrospective survey of medical records in Sen-En Hospital identified 40 patients and 62 ears with PET between September 2014 and June 2015...

OBJECTIVE: To explore the origin of "physiological" ear clicks during deglutition or other pharyngeal movements, which, in contrast to disturbing frequent clicks under pathologic conditions, mostly remain unnoticed by the patient. STUDY DESIGN: Clinical experimental study at a tertiary referral center. METHODS: Ear clicks were recorded by a microphone sealing the external ear canal parallel to endoscopic or manometric evaluations of the Eustachian tube function...

Myringoplasty aims to reconstruct the tympanic membrane, restoring protection to the middle ear and improve hearing. Success of Myringoplasty in terms of anatomical closure is influenced by many factors. This study focuses on the influence of size and site of tympanic membrane perforation on success rate of Myringoplasty. This is a prospective study of 60 patients who underwent myringoplasty and were then followed up for 6 months from the date of operation. Patients with dry perforation, with good cochlear reserve, intact and mobile ossicular chain, functioning Eustachian tube were selected randomly for the operation...

Traditionally, otologists have aimed to produce a clean, dry, safe ear with the best possible hearing result. More recently, "less invasively" has been added to this list of goals. The development of small-diameter, high-quality rigid endoscopes and high-definition video systems has made totally endoscopic, transcanal surgery a reality in adult otology and a possibility in pediatric otology. This article reviews the anatomy of the pediatric middle ear and its surrounding airspaces and structures based on the work of dozens of researchers over the past 50 years...

OBJECTIVES/HYPOTHESIS: Using a retrospective video evaluation of exclusive endoscopic middle ear procedures, we analyzed the different anatomical and pathological findings between patients with attic disease or cholesteatoma and patients without attic disease. STUDY DESIGN: A case-control study based on a retrospective chart review in a tertiary university referral center. METHODS: Videos from endoscopic middle ear procedures carried out between February 2007 and August 2012 were reviewed...

This paper reviews the past and present developments in the treatment of chronic obstructive eustachian tube dysfunction. Alongside tube catheterization and bougie insertion, modern approaches such as laser eustachian tuboplasty and balloon eustachian tuboplasty (BET) are described. In BET, transnasal endoscopic insertion via the pharyngeal ostium places a balloon catheter in the cartilaginous portion of the eustachian tube. This is then dilated to a pressure of 10 bar for 2 min. Up until January 2013, 351 chronic obstructive eustachian tube dysfunction patients had been treated in our department using BET...

The objective of the present study was to analyse the results of he treatment of Eustachian tube dysfunction by means of prolonged transtubal drainage of the tube lumen using a polyethylene catheter introduced immediately after the completion of the rhinosurgical intervention for the targeted delivery of pharmaceutical products. Eighty four patients with Eustachian tube dysfunction and impairment of hearing had a thin catheter introduced in the tube lumen for 7-14 days after various rhinosurgical interventions...

OBJECTIVE: To compare the effect of two different approaches in curettage of adenoid hypertrophy on eustachian tube function: the endoscopic assisted transoral adenoidectomy, and the traditional transoral curette adenoidectomy. METHOD: Clinical data of adenoid hypertrophy patients who underwent surgery therapy were prospectively analyzed; Eustachian tube function were compared among them. RESULT: Both traditional curettage of adenoids through mouth(group TCA) and endoscopic assisted transoral adenoidectomy (group ETA) significantly improved eustachian tube function (P < 0...

Eustachian tube dysfunction is closely related to the development of otitis media and result from several factors including inflammation within the nasal cavity and nasopharynx, adenoid hypertrophy, cleft palate and nasopharyngeal carcinoma. To some extent, eustachian tube dysfunction may be related to weakness of the paratubal muscles, such as the tensor veli palatini and levator veli palatini muscles. The aim of the study is to find out myogenic factors in eustachian tube dysfunction using electromyography (EMG), and to evaluate the clinical feasibility of EMG...
