OBJECTIVE: To assess the efficacy of patulous Eustachian tube handicap inventory (PHI) for patulous Eustachian tube (PET) patients. STUDY DESIGN: Prospective. SETTING: Tertiary referral center. SUBJECTS: A prospective survey of medical records in Sen-En Hospital identified 31 ears of 31 patients with definite PET who received insertion of the silicone plug as surgical treatment group, 29 ears of 29 patients treated with self-instillation of physiological saline solution as conservative treatment group, and 29 ears of 29 patients of sensorineural hearing loss without findings of PET treated between June 2015 and December 2015...

OBJECTIVE: The eustachian tube (ET) has two important functions, ventilation and clearance of the middle ear. We evaluated the ET ventilator function by the sonotubometry and the inflation-deflation test that are widely used today, and the ET clearance function by the saccharin test. Results of both tests were compared with surgical outcomes, and assessed which test was more closely related to the surgical outcomes. STUDY DESIGN: Prospective case series. SETTING: A single university hospital...

CONCLUSIONS: Trans-tympanic plugging of the Eustachian tube (ET) with the silicone plug (Kobayashi Plug) induced long-term effectiveness for over 80% of chronic and severe patulous ET (PET) patients. The New Kobayashi Plug was more effective with fewer complication of plug descent to the pharyngeal orifice. OBJECTIVE: To investigate the effectiveness and complications of trans-tympanic plugging of the ET using a Kobayashi Plug for chronic PET. METHOD: Trans-tympanic plugging of the ET using the Kobayashi Plug was performed for 252 ears of 191 patients...

OBJECTIVE: To determine the effectiveness of augmentation surgery using polydimethylsiloxane elastomer injection for the management of patulous eustachian tube. METHOD: All patients were treated with eustachian tube injection augmentation performed via a combined transnasal-transoral endoscopic approach. Clinical presentation, volume of injection, complications and initial response were all prospectively recorded. Longer-term follow up was conducted through structured telephone interviews using previously described patient-reported outcome measures...

During the last decade, endoscopic surgery of the Eustachian tube (ET) has been advocated for ET dilatory dysfunction and for patulous ET. The internal carotid artery (ICA) and the ET are closely related, and knowledge of their surgical anatomy has become essential. This study was designed to establish the anatomical relationships between the endoscopically critical area along the full length of the cartilaginous ET and its closest association with the ICA. The perpendicular distance between the ET lumen and the ICA was measured from head magnetic resonance images (MRI) at three levels: (A) cartilaginous and bony ET junctional point, (B) mid cartilaginous ET point, and (C) the nasopharyngeal orifice of the cartilaginous ET...

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 determine the relationship between Eustachian tube function and inner ear function in patulous Eustachian tube (pET). METHODS: We encountered a patient with pET accompanied by dizziness that was induced by nasal respiration. Eye movements were recorded using video-oculography, and Eustachian tube function was assessed using a Eustachian tube function analyzer. Horizontal and vertical components of pupil position were assessed to test fixation, positional, and positioning nystagmus...

This study aims to explore the eardrum thickening approach via cartilage myringoplasty for the cessation of symptoms of patulous Eustachian tube (PET), including autophony, aural fullness and breathing synchronous tinnitus. A total of 12 patients who met the diagnosis criteria of PET were included and given an eardrum patching test preoperatively. Then, myringoplasty with ipsilateral full-thickness tragus cartilage under general anesthesia was performed. All patients were followed up for at least 6 months postoperatively...

Patulous eustachian tube (PET) can have a significant negative impact on a patient's quality of life. Several methods of surgical management can be an option to treat PET, and our objective is to evaluate the safety and efficacy of autologous cartilage injection in patients with PET. Thirty-three ears of twenty-five patients with chronic PET refractory to conservative treatment were enrolled to this study. Autologous tragal cartilage was harvested, and chopped into fine pieces to allow its injection using a 1 cc Bruening syringe...

INTRODUCTION: The Eustachian tube is a complex and inaccessible structure, which maintains middle ear ventilation to facilitate transmission of sound from the tympanic membrane to the cochlea. A renewed interest in treatments for eustachian tube dysfunction has led to a demand for methods of imaging the Eustachian tube, and assessing tube opening non-invasively. This review aims to summarise the use of imaging in the anatomical assessment of the Eustachian tube, and to explore how radiological techniques can be used to assess tube function...

Conclusions This study suggests that long-term ventilation tube insertion is the first-choice surgical treatment for a 'sniff-type' patulous Eustachian tube (PET). When treating a refractory PET, it is important to determine whether the patient had a habitual sniff. Objectives PET patients were divided into two groups: patients with a habitual sniff (sniff-type PET) and those without a habitual sniff (non-sniff-type PET). This study examined the effects of ventilation tube insertion or silicone plug insertion in each group...

OBJECTIVES: To evaluate the safety and therapeutic efficacy of trans-tympanic catheter insertion (TCI) in patients with refractory patulous eustachian tube (PET). METHODS: TCI was attempted in thirty-six ears of twenty-nine patients with chronic PET refractory to conservative treatment. The catheter was inserted under local anesthesia in an operating room through the bony orifice of the eustachian tube (ET) to occlude the isthmus of the tube via a myringotomy site on the tympanic membrane...

OBJECTIVE AND DESIGN: To investigate the pathogenesis of cholesteatoma, we planned to conduct a cohort study. As a first step, we conducted an epidemiological study in Fukuoka City, Japan to determine the incidence of cholesteatoma treated both with and without surgery. We also conducted a case-control study to investigate the pathogenesis of cholesteatoma. RESULTS: The annual incidence of cholesteatoma, including cases treated without surgery, was 6.8-10.0 in a population of 100 000...

A 20-year-old man presented with a 6-year history of popping sounds in both ears when he breathed deeply. Aural fullness and autophony of the voice and breathing sounds were also described. Pure-tone audiometry showed normal hearing. Otoscopy showed indrawn and severely atrophic eardrums that moved..

OBJECTIVE: Patulous eustachian tube (PET) can have a significant negative impact on a patient's quality of life. Previous work has demonstrated that temporarily mass loading and stiffening the tympanic membrane significantly reduces these symptoms. This study examined KTP laser myringoplasty (LM) and cartilage tympanoplasty (CT) as a means to manipulate the tympanic membrane to alleviate PET symptoms. STUDY DESIGN: Retrospective case review. SETTING: Academic tertiary care referral hospital...
