OBJECTIVES/HYPOTHESIS: Many objective tests of eustachian tube (ET) function have been devised for clinical and research use but they have not been directly compared or characterized. As a first step to identifying tests to incorporate into an outcome set for ET dysfunction, we assessed repeatability of a panel of eight of these tests in healthy ears. STUDY DESIGN: Comparison of eight tests of ET function. METHODS: The following tests were investigated in combination with Valsalva, Toynbee, swallow, or sniff maneuvers: 1) patient-reported ET opening, 2) observed tympanic membrane movement, 3) continuous impedance, 4) canal manometry, 5) sonotubometry, 6) nine-step test, 7) tubomanometry, and 8) tympanometry at rest...

A 5-y-old, intact, 2.5-kg female domestic rabbit was presented because of blood spatter on the wall of its cage and the toenails of its right hind limb. Physical examination revealed a red, gelatinous mass that spanned the width of the right vertical ear canal. Radiographic images revealed a soft-tissue opacity at the base of the right ear, which was superimposed over the tympanic bulla and extended to the pinna. A CT scan revealed that the soft-tissue mass was within the vertical and horizontal portions of the right external ear canal and extended to the level of the tympanic membrane, with no bony involvement...

BACKGROUND: The tympanoplasty for high-risk tympanic membrane perforation is a challenge. It is necessary to compare the most useful and feasible surgical technics in our environment for these patients. The objective was to compare the cartilage island tympanoplasty for the treatment of high-risk tympanic membrane perforations versus the use of temporalis fascia. METHODS: Randomized controlled clinical trial in 69 patients of ten years or older, diagnosed with high-risk tympanic membrane perforation in a third level hospital...

BACKGROUND: Blast injuries in modern warfare are common, and the ear is often affected as it is an effective pressure transducer. This study aimed to evaluate military blast injuries of the ear. METHODS: From May 2002 to October 2014, all patients referred to two military hospitals near Paris, France following exposure to massive explosions were analysed. RESULTS: Among the 41 patients (82 ears), 36 of them reported tinnitus, 25 hearing loss, 14 earache and 8 vertigo...

This study evaluated the prevalence of minimal hearing loss (MHL) in South Korea based on the 2010 to 2012 Korea National Health and Nutrition Examination Survey. A total of 16,630 representative individuals (older than 12 years) who completed ear examinations and structured questionnaires were analyzed. Only participants who had normal tympanic membranes were included. MHL was categorized into the following three groups: 1) unilateral sensorineural hearing loss (USHL, pure-tone average (PTA) ≥ 15 dB in the affected ear), 2) bilateral sensorineural hearing loss (BSHL, 15 dB ≤ PTA < 40 dB in both ears), and 3) high-frequency sensorineural hearing loss (HFSHL, two or more high-frequency thresholds > 25 dB in either ear)...

Tympanic membrane perforations are due to common otologic problems. The current treatments to heal tympanic membrane perforation, such as myringoplasty, have some disadvantages, including the need for autologous grafting, which is rapidly absorbed by the organism before perforation recovery is complete. To improve the structural and functional tympanic membrane healing after surgery, we propose a new branch of artificial grafts. In this study, we report the development of artificial grafts using electrospun bioabsorbable polymers...

The objective of this study was to evaluate the role of removing middle ear paragangliomas using an ultrasonic aspirator (UA) through a transcanal, exclusively endoscopic approach. Three consecutive patients undergoing transcanal endoscopic resection of middle ear paragangliomas using an UA were retrospectively studied. The primary outcome measure was achieving gross total tumor resection. Secondary outcomes included postoperative hearing and early convalescence. Two glomus tympanicum tumors and one small glomus jugulare were included, and complete tumor resection was achieved endoscopically in all cases...

The Epidemiology of otitis media with spontaneous perforation of the tympanic membrane and associated nasopharyngeal carriage of bacterial otopathogens was analysed in a county in Catalonia (Spain) with pneumococcal conjugate vaccines (PCVs) not included in the immunization programme at study time. A prospective, multicentre study was performed in 10 primary care centres and 2 hospitals (June 2011-June 2014), including all otherwise healthy children ≥2 months ≤8 years with otitis media presenting spontaneous tympanic perforation within 48h...

We aim to demonstrate that regeneration of chronic tympanic perforations with heparin binding epidermal growth factor like growth factor (HB-EGF) delivered by an injectable hydrogel restored hearing to levels similar to that of non-perforated tympanic membranes. Chronic tympanic membrane perforation is currently managed as an outpatient surgery with tympanoplasty. Due to the costs of this procedure in the developed world and a lack of accessibility and resources in the developing countries, there is a great need for a new treatment that does not require surgery...

CONCLUSION: A tentative conclusion was made that the finite element method can be used to investigate the fatigue life of the tympanic membrane after ossiculoplasty; the main reason of the extrusion of the tympanic membrane may not be blamed to the fatigue mechanism under normal sound pressure. OBJECTIVE: This study was to investigate the extrusion of the prosthesis from the tympanic membrane at post-ossiculoplasty by finite element method. METHODS: A finite element model of the human middle ear has been constructed and used as the model of the constructed middle ear at post-ossiculoplasty...

We conducted a retrospective chart review to characterize the outcomes of 12 patients-9 men and 3 women, aged 21 to 79 years (mean: 49)-who had been treated at our tertiary care center for acute bacterial meningitis caused by acute otitis media (ABMAO). Fever was the most common presenting sign/symptom, observed in 8 patients, followed by otalgia, neck stiffness, headache, and confusion. An opaque and bulging tympanic membrane was observed in 8 patients. Cultures were positive for Streptococcus pneumoniae in the cerebrospinal fluid, ear, and blood in 7, 5, and 3 patients, respectively...

OBJECTIVE: The objective of this study was to evaluate safety and efficacy of regenerative treatment using gelatin sponge with basic fibroblast growth factor (bFGF) in patients with tympanic membrane perforation (TMP). METHODS: The current study was a prospective, multicenter, open-label, single-arm, and exploratory clinical trial to evaluate the safety and efficacy of the TM regeneration procedure (TMRP). Myringotomy was used to mechanically disrupt the edge of the TMP, and a gelatin sponge immersed in bFGF was then placed over the perforation...

OBJECTIVE: The tympanomeatal flap elevation technique has been used in tympanoplasty for decades; however, this procedure has disadvantages. In recent years, endoscopic transcanal myringoplasty (ETM) has been increasingly practiced and has yielded positive results.This study compares the efficacy of ETM and endoscopic type I tympanoplasty (ETT) in repairing medium-sized perforations of the tympanic membrane. METHODS: This retrospective medical record review included patients undergoing surgery for medium-sized perforations of the tympanic membrane from January 1, 2013 to August 1, 2015...

Objectives Pediatric eustachian tube dysfunction (ETD), otitis media with effusion (OME), and tympanic membrane retraction (TMR) have been well studied, but no large analyses have described the associated burden beyond childhood. The potential impact and feasibility of prospective trials designed to optimize management of affected adults are thus unclear. Our objectives were therefore (1) to determine the national visit burden associated with ETD/OME/TMR beyond childhood and (2) to examine risk factors specific to adults, highlighting differences in comparison with children...

OBJECTIVES: To evaluate the aetiologic role of the main bacterial pathogens associated with acute otitis media (AOM) in children with AOM and spontaneous tympanic membrane perforation (STMP). METHODS: Between May 1, 2015 and April 30, 2016, 177 children, 6 months to 7 years old, with AOM complicated by STMP within 12 h were prospectively enrolled. Middle ear fluid (MEF) was tested by real-time polymerase chain reaction for Streptococcus pneumoniae, nontypeable Haemophilus influenzae, Streptococcus pyogenes, Moraxella catarrhalis and Staphylococcus aureus...
