OBJECTIVE: To assess the role of Rho/Rho-kinase pathway in the pathogenesis of cholesteatoma. MATERIALS AND METHODS: Thirty-eight patients with cholesteatoma, who had gone mastoidectomies were enrolled in this prospective study. Cholesteatomas matrix (CM) and a piece of the external ear canal skin (EECS as control) were taken and transferred to the liquid nitrogen and kept at -86 °C for Rho A and Rho-kinase (ROCK) analysis with Western blotting and commercial ELISA kits (Cell Biolabs Inc...

OBJECTIVE: The aim of this study was to compare the hearing results of embedding the partial ossicular reconstruction prosthesis (PORP) underneath the malleus with the malleus relocation technique and tympanic membrane graft in the presence of the malleus. MATERIALS AND METHODS: A retrospective review of patient charts and audiometric results in a tertiary referral center was conducted. In total, 83 patients who underwent intact canal tympanoplasty with mastoidectomy between 2010 and 2015 were included and divided into two different groups: malleus assembly to the stapes head (MASH) and tympanic membrane assembly to the stapes head (TASH)...

Chondromyxoid fibroma (CMF) is an extremely rare lesion of the skull base. This histologic type typically predilects metaphysis of the long bones. It is locally invasive/infiltrative, and this tendency is more concerning in the skull base, where a radical resection is often technically impossible because of the presence of vital neurovascular structures. We present a case of a 19-year-old woman who presented with a sudden onset of right facial weakness, progressively worsening to a severe disfiguring motor weakness...

The objective of the present paper was to acquire information about the mastoidectomy size necessary to obtain an optimal placement of the direct acoustic cochlear implant actuator and fixation system. Ten human cadaveric temporal bones were dissected and implanted with direct acoustic cochlear implant. Mastoidectomy size was determined after implantation in each temporal bone. A bone bed for the receiver/stimulator, mastoidectomy and a large posterior tympanotomy were drilled out. The mastoidectomy was progressively enlarged posteriorly in small steps until the actuator template was judged adequately oriented to enable passage of the rod through the posterior tympanotomy without any contact with the bony walls...

OBJECTIVE: Cholesteatoma patients have a high risk of recurrence with complications, and knowledge exchange is a prerequisite for improving treatment. This study aimed to apply appropriate statistics to provide meaningful and transferable results from cholesteatoma surgery, to highlight independent prognostic factors, and to assess the incidence rate. METHODS: Incidence rates were assessed for the district of Aarhus, Denmark. From 147 patients operated on mainly with canal wall up mastoidectomies for debuting cholesteatomas, 10-year Kaplan-Meier recidivism rates were calculated and independent prognostic factors for the recidivism were identified by Cox multivariate regression analyses...

BACKGROUND: Hearing can be induced not only by airborne sounds (air conduction [AC]) and by the induction of skull vibrations by a bone vibrator (osseous bone conduction [BC]), but also by inducing vibrations of the soft tissues of the head, neck, and thorax. This hearing mode is called soft tissue conduction (STC) or nonosseous BC. PURPOSE: This study was designed to gain insight into the mechanism of STC auditory stimulation. RESEARCH DESIGN: Fluid was applied to the external auditory canal in normal participants and to the mastoidectomy common cavity in post-radical mastoidectomy patients...

Juveria Majeed, L Sudarshan Reddy
Chronic Suppurative Otitis Media (CSOM) is a chronic inflammation of middle ear cleft. It presents with discharging ear and decreased hearing. The diagnosis is mostly on clinical examination with otoscope or oto endoscope. Computerised Tomography (CT) of mastoids is done to evaluate the extent of the disease and its complication. High resolution CT is now the investigation of choice for temporal bone disease. This study emphasizes on the importance of CT scan in diagnosis of inflammatory ear diseases and most importantly identifying pitfalls or complications which a surgeon can come across during surgery...

The aim of the study was to evaluate insertion forces during manual insertion of a straight atraumatic electrode in human temporal bones, and post-implantation histologic evaluation of the samples to determine whether violation of intracochlear structures is related to insertion forces. In order to minimize intracochlear trauma and preserve residual hearing during cochlear implantation, knowledge of the insertion forces is necessary. Ten fresh frozen human temporal bones were prepared with canal wall down mastoidectomy...

OBJECTIVE: To describe cases of complicated middle ear infections in children with cochlear implants (CI), i.e., episodes of acute otitis media (AOM) and acute mastoiditis (AM), resulting in hospitalization. METHODS: A total of 206 children under 16 years (300 implantations) were implanted between 1 January 2008 and 31 December 2014 at the West Danish CI Center, Department of Otorhinolaryngology Head and Neck Surgery, Aarhus, Denmark. By means of two prospective local databases, episodes of AOM or AM and demographics were retrieved including biochemistry, microbiology, length of follow- up, and variable treatment modalities (intravenous (IV) antibiotics, revision mastoidectomy, and insertion of ventilation tubes)...

INTRODUCTION: A consensus is emerging amongst otologists that obliteration of the mastoid cavity that results after modified radical mastoidectomy is a sound option to prevent cavity related problems such as otorrhoea, infection, granulation tissue and hearing loss. A variety of techniques have been proposed to perform the obliteration. AIM: The present study aimed to compare the conventional method of mastoid cavity obliteration by vascularised temporalis myofascial flap with deep temporal fascial-periosteal flap in canal wall down mastoidectomy...

OBJECTIVES: Dissection of cadaveric temporal bones (TBs) is considered the gold standard for surgical training in otology. For many reasons, access to the anatomic lab and cadaveric TBs is difficult for some facilities. The aim of this prospective and comparative study was to evaluate the usefulness of a physical TB prototype for drilling training in residency. DESIGN: Prospective study. SETTING: Tertiary referral centre. PARTICIPANTS: Thirty-four residents were included...

OBJECTIVES: The authors' aim was to investigate whether serum neutrophil to lymphocyte ratio might be used as a predictive biomarker to help differentiate active from inactive chronic otitis media (COM). METHODS: Two hundred fifty-nine patients having inactive COM received tympanoplasty without mastoidectomy and were identified as Group 1. On the other hand, 254 patients having active COM received tympanoplasty with mastoidectomy and were identified as Group 2. Routine hemogram tests were performed preoperatively for both the groups...

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...
