Eustachian tube dysfunction is believed to be an important factor to cholesteatoma development and recurrence of disease after surgical treatment. Although many studies have described prognostic factors, evaluation methods, or surgical techniques for Eustachian tube dysfunction, they relied on the soft tissues of its structure; little is known about its bony structure-the protympanum-which connects the Eustachian tube to the tympanic cavity, and can also be affected by several inflammatory conditions, both from the middle ear or from the nasopharynx...

OBJECTIVE: To retrospectively evaluate the long-term results of surgery for retrograde bone work, using soft-wall reconstruction of the canal wall, for pediatric cholesteatoma. METHODS: We retrospectively evaluated a series of 25 consecutive ears of 24 patients who were ≤16 years of age. All children underwent cholesteatoma surgery between October 2002 and August 2008. The type of cholesteatoma, the length of follow-up, the incidence of residual and recurrent cholesteatoma, postoperative hearing results, and the form of the reconstructed external canal wall and tympanic membrane were assessed...

CONCLUSION: The middle ear pressure changes detected during BET can be directly attributed to the balloon inflation and may represent a second, immediate, mechanism of action of BET. BET seems to be safe with respect to the risk of a barotrauma. Further human studies are now necessary to confirm the results and gain more insight into the mechanism of action of BET. OBJECTIVE: Since the introduction of Balloon Eustachian Tuboplasty (BET) as a treatment of chronic Eustachian tube dysfunction, the precise mechanism of action is unknown...

Hearing loss as a side effect in patients with head and neck malignancies with chemoradiation is frequently ignored. Its effects on auditory functions are less studied and there are studies done on animals which are less reliable. The present study was undertaken to identify the type of hearing loss and also to quantify the degree of hearing loss in these patients. A prospective, descriptive study was undertaken in histologically proven head and neck cancer patients treated with cobalt 60 teletherapy who received a dose of 60-66 Grays (Gy) over a period of 6-7 weeks with concurrent Cisplatin 30 mg/m(2) once weekly for 6 weeks...

PURPOSE: Otitis media (OM) is a frequent occurrence in the cleft palate population. Palate repair is thought to positively contribute to Eustachian tube function. The purpose of this study is to determine the proportion of cleft patients in our cohort with OM, and if palatoplasty closure technique influences future OM differently. The authors posited that Z-plasty palate repair would result in improved Eustachian tube function, compared with straight-line repair. METHODS: Patient records were accessed and data was recorded on palatoplasties from 2005 to 2007 as well as from 2012 to 2014...

BACKGROUND: Imaging the Eustachian tube has proven difficult as it has an anatomical orientation that is not aligned with standard planes. In addition, the Eustachian tube is a dynamic structure, opening briefly during a variety of physiological manoeuvres. CASE REPORT: A 54-year-old healthy and asymptomatic man underwent computed tomography utilising an area detector scanner. Multiplanar reconstruction was performed at 1 mm intervals. In addition, dynamic clips were constructed to demonstrate air and its movement in the field...

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...

OBJECTIVE: Balloon eustachian tuboplasty (BET) has entered clinical use as a treatment for eustachian tube dysfunction. Some surgeons perform myringotomy prior to BET due to concerns that the increase in middle ear (ME) pressure caused by BET may cause otic barotrauma. We investigated the ME pressure changes occurring during BET in cadavers. STUDY DESIGN: Human cadaver investigation of a surgical technique SETTING: Laboratory study at a tertiary referral center...

Repair of the cleft palate intends to establish the division between the oral and nasal cavity, thereby improving feeding, speech, and eustachian tube dysfunction all while minimizing the negative impact on maxillary growth. Before palate repair candidacy, timing and surgical method of repair is dependent on comorbid conditions, particularly cardiac disease, mandibular length, and palate width. Additionally, management of the alveolar cleft and the indications for gingivoperiosteoplasty versus secondary alveolar bone grafting is a controversial topic that weighs the risks and benefits of potentially sparing the patient an additional surgery against iatrogenic restriction of facial growth and malocclusion...

BACKGROUND: Barotrauma is a frequent problem in aviation medicine. Eustachian tube dysfunction plays a critical role in the pathogenesis of barotrauma. Function of the Eustachian tube can be indirectly assessed by multifrequency tympanometry, which provides valuable information about the resistance and permeability of the middle ear in a wide frequency range. The aim of this study was to research whether multifrequency tympanometry could be used for assessing middle ear impairments in pilots...

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: Conventional treatment for acute otitis media mainly targets bacteria with antibiotics, neglecting to control for mediators of inflammation. Mediators of inflammation, such as leukotrienes, have been identified in patients with acute otitis media (AOM) or subsequent secretory otitis media (SOM). They can cause functional eustachian tube dysfunction or increase mucous in the middle ear, causing persistent SOM following AOM. The objective of the present study was to evaluate whether or not administration of pranlukast, a widely used leukotriene C4, D4, and E4 antagonist, together with antibiotics could inhibit the progression to SOM...

OBJECTIVE: To assess the acoustic transmission characteristics of the Eustachian tube (ET) in living subjects in verified patent and closed ET states to facilitate the detection and quantification of ET function using acoustic measures such as sonotubometry. PATIENTS: The two subjects in this study had no history of ear disease nor previous ear surgery and were capable of volitionally opening and closing their ET. INTERVENTIONS: Tympanometry and otologic examinations were used to confirm ET patent and closed states by observing tympanic membrane movement with respiration and by acoustic immitance measurements during forced respiration...

OBJECTIVE: Baro-challenge-induced Eustachian tube (ET) dysfunction is defined as the presence of aural discomfort, popping, or pain, which only arises in case of ambient pressure changes, without abnormalities on otoscopy or tympanometry. Our primary aim was to determine the discriminative power of the 7-item Eustachian Tube Dysfunction Questionnaire (ETDQ-7) in patients with baro-challenge-induced ET dysfunction in comparison with that in healthy controls. The secondary aim was to determine the responsiveness of ETDQ-7 in patients with baro-challenge-induced obstructive ET dysfunction who underwent balloon dilation tuboplasty (BDET)...

A late detection of hearing impairment in children can affect speech and language development. Otitis media with effusion (OME) associated with risk factors like recurrent upper respiratory tract infections (URTI) is considered the most common cause of silent hearing impairment among children. So this study was carried out to screen such at risk children for hearing impairment. The study was conducted on 1000 children in the age group of 2-12 years who presented to the OPD of ENT and Pediatrics Department, Govt Medical College with the complaint of recurrent URTI...
