Development of intracranial complications from middle ear infections might be difficult to diagnose. We compared radiological and surgical findings of 26 patients affected by otogenic meningitis. Results of our analysis showed that surgery is more reliable than imaging in revealing bone defects. Therefore, suggest that surgery be performed for diagnosis and eventual management of all cases of suspected otogenic meningitis.

BACKGROUND: Eustachian tube dysfunction is a poorly defined condition associated with various symptoms and it can predispose to middle-ear disease. Balloon dilation Eustachian tuboplasty has been proposed as a treatment for Eustachian tube dysfunction. OBJECTIVE: To evaluate the subjective and objective outcomes of balloon dilation Eustachian tuboplasty in patients with recurrent, previously treated chronic Eustachian tube dysfunction. METHODS: The study was conducted on 11 patients (13 ears) who had undergone previous unsuccessful medical and surgical treatment...

Aim of the present study is to evaluate the long term results of ossiculoplasty using titanium clip prosthesis. A retrospective analysis with prospective follow-up has been done including for all patients who had a Clip-PORP implanted between the years 2002-2013. Following this, audiometric hearing results were measured with clinical examination including otoscopy and quality of life evaluation using Glasgow benefit inventory. 48 patients (51 ears, 29 men, 19 women, average age 44.1 years) received followed up after an average duration of 6...

BACKGROUND: Positive airway pressure (PAP) devices are used as treatment for obstructive sleep apnea (OSA). PAP may increase middle ear pressure which is of interest to otologic surgeons. There is a lack of data to guide management of PAP therapy after middle ear surgery. OBJECTIVE: To elucidate how otologic surgeons manage PAP in their patients after ear surgery. STUDY DESIGN: A survey e-mailed to practicing members of the American Neurotology Society...

CONCLUSION: This study validates that a finite element model of the human ossicular chain and tympanic membrane can be used as an effective surgical assessment tool in clinics. OBJECTIVE: The present study was performed to investigate the application of a finite element model of ossicular chain and tympanic membrane for fabrication of individualized artificial ossicles. METHODS: Twenty patients (20 ears) who underwent surgery for middle ear disease (n = 20) and 10 healthy controls (10 ears) were enrolled in the hospital...

CONCLUSIONS: The heparin-binding epidermal growth factor-like growth factor (HB-EGF) plays an essential role in the development and invasiveness of cholesteatoma. This study may help to realize the molecular mechanisms underlying the pathogenesis of cholesteatoma and make HB-EGF a promising target for drug intervention of cholesteatoma. OBJECTIVE: To detect HB-EGF expression in human surgical specimens of acquired middle ear cholesteatoma and analyze its functional role as a regulator of epithelial keratinocytes hyperproliferation...

INTRODUCTION: Boric acid, which has antiseptic and acidic properties, is used to treat external and middle ear infections. However, we have not found any literature about the effect of boric acid powder on middle ear mucosa and inner ear. OBJECTIVE: The purpose of this study is to investigate possible ototoxic effects of boric acid powder (BAP) on cochlear outer hair cell function and histological changes in middle ear mucosa in a rat animal model. METHODS: Twenty healthy, mature Wistar albino rats were used in this study...

PURPOSE OF REVIEW: Eosinophilic otitis media (EOM) is a refractory disease characterized by the accumulation of eosinophils in middle ear effusion and mucosa. We summarize current knowledge regarding the clinical characteristics and management of EOM. Although eosinophil activation in inflamed foci is involved in the pathogenesis of EOM, little is known about the fate of the eosinophils and aftermath of their cell death. We discuss the possibility that eosinophils undergo non-apoptotic cell death that worsens tissue damage and increases effusion viscosity...

BACKGROUND: Reconstruction of external ear is important for the child/adult with craniofacial deformities to achieve balance and harmony of the face and head. The aim of this study was to investigate the clinical application of an expanded two-flap method for auricular reconstruction in hemifacial microsomia.

Tympanoplasty was conventionally performed using a microscope for decades. However, since the endoscope began to be used in middle ear surgery in the 1970s, endoscopic tympanoplasty has gained increasing attention. The main objective of this study was to compare endoscopic and microscopic tympanoplasty with and without ossiculoplasty, demonstrating the potential advantages, disadvantages, and outcomes of each. This retrospective study included 126 patients with chronic otitis media who received tympanoplasty from 2013 to 2015 in our hospital...

OBJECTIVE: Making a 3-dimensional (3D) temporal bone model is simple using a plaster powder bed and an inkjet printer. However, it is difficult to reproduce air-containing spaces and precise middle ear structures. The objective of this study was to overcome these problems and create a temporal bone model that would be useful both as a training tool and for preoperative simulation. METHODS: Drainage holes were made to remove excess materials from air-containing spaces, ossicle ligaments were manually changed to bony structures, and small and/or soft tissue structures were colored differently while designing the 3D models...

BACKGROUND: Surgical approaches for removal of vestibular schwannoma are done through retrosigmoid, translabyrinthine, or middle fossa approaches, depending on the tumor size, preoperative hearing status, surgical team experience, and patient preference. The middle fossa approach (MFA) for the vestibular schwannoma (VS) route preserves hearing and can be done with minimal morbidity and mortality. METHOD: The authors discuss the surgical anatomy of the middle fossa, internal auditory canal localization techniques, MFA indications and the procedure for VS removal, and outcome...

REVIEW
S E J Connor
There have been significant advances in the diversity and effectiveness of hearing technologies in recent years. Implanted auditory devices may be divided into those that stimulate the cochlear hair cells (bone conduction devices and middle ear implants), and those that stimulate the neural structures (cochlear implants and central auditory implants). Contemporary preoperative and postoperative imaging may be used to help individualise implant selection, optimise surgical technique and predict auditory outcome...

Marite Palma Diaz, Juan Carlos Cisneros Lesser, Alfredo Vega Alarcón
Introduction Superior semicircular canal dehiscence syndrome was described by Minor et al in 1998. It is a troublesome syndrome that results in vertigo and oscillopsia induced by loud sounds or changes in the pressure of the external auditory canal or middle ear. Patients may present with autophony, hyperacusis, pulsatile tinnitus and hearing loss. When symptoms are mild, they are usually managed conservatively, but surgical intervention may be needed for patients with debilitating symptoms. Objective The aim of this manuscript is to review the different surgical techniques used to repair the superior semicircular canal dehiscence...

Our objectives in reporting this case series are to familiarize readers with the rare occurrence of paragangliomas originating along the facial nerve and to provide a literature review. We describe 3 such cases that occurred at our tertiary care academic medical center. Two women and 1 man presented with a tumor adjacent to the vertical segment of the facial nerve. The first patient, a 48-year-old woman, presented with what appeared to be a parotid tumor at the stylomastoid foramen; she underwent a parotidectomy, transmastoid facial nerve decompression, and a shave biopsy of the tumor...

OBJECTIVE: The objective of this study is to evaluate the anatomical variability of round and oval window regions and its relationship with their closest structures, to determine its implication on the fitting and stabilization of the middle ear implant Vibrant Soundbridge. METHODS: Variations of the anatomy of round and oval window regions were assessed in a total of 85 human dissected temporal bones. Afterward, we evaluated the adaptation and subsequent stabilization of the floating mass transducer (FMT) of the Vibrant Soundbridge in 67 cases in round window (RW) and in 22 cases in oval window (OW), and the influence that the variability of the different anatomical features examined had on this stabilization...
