BACKGROUND: Endoscopic ear surgery is becoming an accepted technique in otological surgery, in the management of chronic otitis media. METHODS: The technique was introduced to the humanitarian care setting of an ear camp in Nepal to consider the appropriateness of the technique in this type of clinical setting. RESULTS: Fifteen cases of myringoplasty were successfully completed. CONCLUSION: The apparent advantages of the endoscopic approach over the traditional microscopic one were the ease of transporting the equipment and the optimal view obtained of the tympanic membrane...

BACKGROUND: Ear symptoms are common among patients presenting to a rhinology clinic. Validated inventories are available for patient quality-of-life in sinonasal disease and Eustachian tube dysfunction (ETD). This study sought to determine the extent of ETD symptoms, using validated metrics, in a large population of patients presenting to a tertiary rhinology clinic. METHODS: Seven-item Eustachian Tube Dysfunction Questionnaires (ETDQ-7) and 22-item Sino-Nasal Outcome Tests (SNOT-22) were prospectively collected from 492 patients treated in a tertiary rhinology clinic...

The Saami are the only indigenous population in Europe and their traditional living area is northern Scandinavia. Hearing impairment (HI) among Saami has not been studied before. The objective was to investigate the presence and type of HI among Saami adults, aged 49-77 years (median age 61 years), living in northern Finland. In addition, the presence of self-reported hearing difficulties, difficulties to hear in background noise and tinnitus were studied. An epidemiological, cross-sectional study encompassing a structured interview, otological examination and audiometry was performed...

Nanoparticles are promising therapeutic options for inner ear disease. In this report, we review in vivo animal studies in the otologic field using nanoparticles over the past 5 years. Many studies have used nanoparticles to deliver drugs, genes, and growth factors, and functional and morphological changes have been observed. The constituents of nanoparticles are also diversifying into various biocompatible materials, including poly(lactic-co-glycolic acid) (PLGA). The safe and effective delivery of drugs or genes in the inner ear will be a breakthrough for the treatment of inner ear diseases, including age-related hearing loss...

OBJECTIVE: Conventional otoscopes and oto-endoscopes, which are used to examine the tympanic membrane (TM), do not provide tomographic information. Optical coherence tomography (OCT) non-invasively reveals the depth-resolved internal microstructure of the TM with very high spatial resolution. We designed this study to examine the TMs with middle ear diseases using a handheld otoscope employing 860 nm spectral domain (SD)-OCT, combined with video camera and to demonstrate the clinical applicability of this system...

Many studies have attempted to correlate chronic otorrhea in children and in adults with the sensorineural hearing loss in the affected ear, with contradictory results. This loss might be the result of the likely toxicity of the bacteria involved, effects of inflammatory cytokines, or constant use of ototoxic antibiotics. All studies evaluated to date compared the affected ear with the normal contralateral ear. From the digitized archive of otologic surgery files of the Department of Otorhinolaryngology at Santa Casa de São Paulo School of Medical Sciences, the ears of patients with chronic otorrhea were evaluated visually and compared with the normal contralateral ears...

INTRODUCTION: Tympanic membrane cholesteatoma (TMC) is a rare anomaly found in pediatric patients with no significant otologic history. Its pathogenesis appears distinct from congenital mesotympanic cholesteatoma. This systematic review and meta-analysis evaluates the management of TMC. METHODS: Two authors independently conducted a systematic review using the PubMed-NCBI, Cochrane Library, and Web of Science databases. Studies describing cases of pediatric TMC were included...

Ear and temporal bone imaging is essential for the diagnostic and preoperative management of middle ear lesions. The scanner is the exam of choice to analyze the walls and the contents of the middle ear. MRI is used to characterize the opacities of the middle ear and to evaluate possible neurological complications. Modern imaging techniques allow intraoperative guidance in otological surgery. Hearing implants are not always a contraindication to MRI but require precautions according to the type of implant.

The advent of the endoscope has facilitated otological surgery in recent years. Advances in optical technology have led to the development of high definition visualisation, such as 4K magnification. Narrow band imaging (NBI) has been shown to improve visualisation of tissue based on varying degrees of vascularity. This is a feasibility study, the first of its kind, aiming to investigate the appearances of middle ear anatomy and pathology (tympanic membrane, tympanosclerosis, cholesteatoma, granulation, endolymphatic sac hydrops, otosclerosis) under the NBI filter, using a high definition 4K endoscope...

OBJECTIVE: Tinnitus is a common otological condition that affects almost 10% of US adults. Research suggests that college students are vulnerable to tinnitus and hearing loss as they are exposed to traumatic levels of noise on a regular basis. Tinnitus and its influence in daily living continue to be underappreciated in the college-aged population. Therefore, the objective for the present study was to analyze prevalence and associated risk factors of tinnitus and tinnitus-related handicap in a sample of college-aged students...

PURPOSE: Determine whether specific risk factors, symptoms and clinical examination findings are associated with hyperbaric oxygen therapy (HBOT) intolerance and subsequent tympanotomy tube placement. MATERIALS AND METHODS: A retrospective case series with chart review was conducted from 2007 to 2016 of patients undergoing HBOT clearance at a tertiary care university hospital in an urban city. Eighty-one (n=81) patient charts were reviewed for risk factors, symptoms and clinical examination findings related to HBOT eustachian tube dysfunction and middle ear barotrauma...

Endoscopic ear surgery (EES) is increasingly a preferred technique in otologic society. It offers excellent visualization of the anatomical structures directly and behind the corners with variable angled telescopes. It also provides reduced operative morbidity due to being able to perform surgical interventions with less invasive approaches. Operative preparation and setup time and cost of endoscopy system are less expensive compared with surgical microscopes. On the other hand, the main disadvantage of EES is that the surgery has to be performed with 1 single hand...

BACKGROUND: Methylene blue is widely used in the medical field, especially as a blue dye for staining. It is also used as a photosensitizing agent in antimicrobial photodynamic therapy, which once photoactivated is effective for the eradication of several multi-resistant bacteria. The objective of this study was to investigate the ototoxic potential of methylene blue and precise its use in otology. METHODS: It was a prospective animal study performed on guinea pigs in our tertiary medical center...

Imaging of middle-ear cholesteatoma with diffusion-weighted imaging (DWI) magnetic resonance imaging (MRI), and inner-ear endolymphatic hydrops (in Ménière's disease) with post-gadolinium high-resolution MRI, are reviewed. DWI MRI provides for a more specific diagnosis of tympano-mastoid cholesteatoma. There is an established and increasing role of DWI MRI in detecting both primary and postoperative cholesteatoma, localising disease, and planning surgery. The contemporary diagnostic accuracy of DWI is reviewed, pitfalls in interpretation are described, and potential future developments are highlighted...
