OBJECTIVE: A method for rating surgical performance of a mastoidectomy procedure that is shown to apply universally across teaching institutions has not yet been devised. This work describes the development of a rating instrument created from a multi-institutional consortium. DESIGN: Using a participatory design and a modified Delphi approach, a multi-institutional group of expert otologists constructed a 15-element task-based checklist for evaluating mastoidectomy performance...

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...

The anatomical area exposed through the exposure of Trautmann's triangle may not be sufficient. We studied the additional exposure provided by skeletonizing the sigmoid sinus. Human cadaver heads were subjected to a thin temporal bone CT scan for a total of 10 sides. The estimated surgical working angle was calculated based on the relationship of the sigmoid sinus to the posterior semicircular canal, superior petrosal sinus and jugular bulb on imaging. The heads were then subjected to a mastoidectomy and remeasured with and without sigmoid sinus skeletonization...

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...

Functional outcomes and complications in otosclerosis surgery are governed by the surgeon's experience. Thus, teaching the procedure to residents to guide them through the learning process as quickly as possible is challenging. Artificial 3D-printed temporal bones are replacing cadaver specimens in many institutions to learn mastoidectomy, but these are not suitable for middle ear surgery training. The goal of this work was to adapt such an artificial temporal bone to aid the teaching of otosclerosis surgery and to evaluate this tool...

CONCLUSION: Patients with mastoiditis and chronic suppurative otitis media which has small mastoids that make them ideal candidates for modified canal wall down mastoidectomy (MCWD) which contributes to a dry and spacious ear and the maintaining and improving hearing. OBJECTIVES: To evaluate surgical outcomes for chronic otitis media underwent MCWD. METHODS: A clinical retrospective study was performed on 47 ears with chronic otitis media which has relatively limited attic lesions have the small, sclerotic and hypocellular mastoids according to the preoperative high-resolution CT scan of the temporal bone that underwent MCWD and 32 ears with typical canal wall down operation form January 2010 to January 2016...

Methemoglobin is an oxidized form of hemoglobin. NADH methemoglobin reductase deficiency or inactivity is the cause of methemoglobin. Excessive production, resulting in accumulation, causes methemoglobinemia. It can be congenital or acquired. We present a case of dormant congenital methemoglobinemia detected accidentally on preoperative assessment, due to low oxygen saturation even at F1O2-1.0 associated with central cyanosis. The patient had 27.7 % methemoglobin, living his life without any complications...

We report a case of methicillin-resistant Staphylococcus aureus (MRSA) otorrhea with impression material of hearing aid in the middle ear. The patient had chronic otitis media in the right ear with sensorineural hearing loss in both ears. The silicone flowed into the middle ear through a tympanic membrane perforation during the process of making an ear mold. Several days after hearing aid fitting, the patient had severe otalgia, intractable otorrhea, aggravated hearing loss, and dizziness. The pus culture and sensitivity test revealed MRSA...

Introduction After mastoidectomy, patients usually complain of bone depressions in the retroauricular region in the surgical site, especially in procedures that require extensive cortical resections. This causes inconveniences such as difficulty wearing glasses, cleaning, and aesthetics complaints. Objective This study aims to describe a vascularized flap surgical technique that uses the mastoid cortical bone adhered to the periosteum, which is pedicled on the anterior portion and repositioned at the end of the surgery...

When acute mastoiditis occurs in cochlear implant recipients, it can progress to subsequent retroauricular abscess due to the absence of the external mastoid cortex resulting from mastoidectomy performed for cochlear implantation. The management goal is to control infection while preserving the implanted device. A 2-year-old boy with cochlear implants developed acute mastoiditis and a subsequent retroauricular abscess. The patient underwent a surgical intervention based on the diagnosis made utilizing gray-scale and power Doppler sonography...

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...
