A 59-yr-old man presented with intraventricular hemorrhage and was found to have a large temporo-occipital arteriovenous malformation (AVM), Spetzler-Martin grade 4. The preoperative intra-arterial digital subtraction angiography (IADSA) showed the AVM was 4 × 4 cm2, had superficial and deep venous drainage, and was fed by multiple branches of the posterior cerebral artery and middle cerebral artery. Preoperative embolization was done in 4 stages. He underwent a left temporo-occipital craniotomy, mastoidectomy, and retrosigmoid craniotomy with a posterior temporal approach...

An inverted papilloma is a benign neoplasm that occurs exclusively in the sinonasal cavity; an inverted papilloma involving the mastoid cavity is extremely rare. We present the case of a patient with an inverted papilloma of the mastoid cavity secondary to cholesteatoma surgery. No case that occurred after acquired cholesteatoma has been reported in literature. A 39-year-old female who was diagnosed with cholesteatoma was treated with a modified radical mastoidectomy in 1988. After recurrence, the patient underwent a canal wall down mastoidectomy in 2006...

In case of cholesteatoma with intact ossicular chain, the primary aims of surgery are complete removal of the cholesteatoma matrix and reconstruction of a dry and safe middle ear; if possible, ossicular chain continuity and therefore the preoperative hearing must be preserved. The aim of this retrospective study is to present the experience of the U.O.C. Otorinolaringoiatria Universitaria of University of Bari "Aldo Moro" in treatment of intact ossicular chain cholesteatoma with Bondy modified radical mastoidectomy (BMRM) and canal wall up tympanoplasty (CWUT)...

Bezold's abscess is a very rare extracranial complication of acute mastoiditis. Lateral sinus thrombosis is another intracranial complication of acute mastoiditis that can occur, but there are only few reports of concomitant ispilateral Bezold's abscess and lateral sinus thrombosis with favorable outcome. We diagnosed and treated successfully a 14-year-old girl suffering from Streptococcus pneumoniae acute mastoiditis complicated with Bezold's abscess and lateral sinus thrombosis. Surgical treatment included myringotomy, cortical mastoidectomy, and Bezold's abscess incision and drainage...

OBJECTIVES: The aim of the study was to evaluate risk factors influencing the results of tympanoplasties on the base of material taken from the Department of Otolaryngology and Laryngological Oncology Collegium Medicum of Nicolaus Copernicus University in Bydgoszcz between 2004-2009. In this period 98 operations were done. The time from operation to hearing examination was 3 to 7 years, mean 5,43. Tympanoplastic operation were divided according to Tos classification. Measuring hearing results, tonal audiometry was done and mean air bone gap on four frequencies was assesed (500, 1000, 2000, 3000 Hz), according to AAO-HNS guidelines (1995)...

OBJECTIVE: Identify the 3D printed material that most accurately recreates the visual, tactile, and kinesthetic properties of human temporal bone Subjects and Methods: Fifteen study participants with an average of 3.6 years of postgraduate training and 56.5 temporal bone (TB) procedures participated. Each participant performed a mastoidectomy on human cadaveric TB and five 3D printed TBs of different materials. After drilling each unique material, participants completed surveys to assess each model's appearance and physical likeness on a Likert scale from 0 to 10 (0 = poorly representative, 10 = completely life-like)...

OBJECTIVES: Literature review shows a limited number of studies investigating chronic pain following ear surgeries. The effect of mastoidectomy on chronic postsurgical pain, however, has never been investigated. The present study investigates not only the incidence and severity of chronic pain following ear surgeries with and without mastoidectomy, but also predisposing diseases for pain. PATIENTS AND METHODS: The study was performed in a total of 150 patients who underwent tympanoplasty or tympanomastoidectomy through a retroauricular incision in a single tertiary health care center...

Introduction  Canal wall down (CWD) mastoidectomy has many drawbacks, including chronic otorrhea not responding to medications, granulations, dizziness on exposure to cold or hot water, and tendency of debris accumulation in the mastoid cavity, demanding periodic cleaning. Many of these problems can be solved by reconstruction of the posterior meatal wall (PMW). Objectives  To assess the results of PMW reconstruction after CWD mastoidectomy for cholesteatoma using titanium mesh and platelet-rich plasma (PRP) mixed with bone pate...

Schneiderian papillomas (ISP) of the middle ear are uncommon conditions, with only 45 cases published within literature. They are locally aggressive tumours, with a high rate of recurrence and associated malignancy. We present a rare case of a 53-year-old man presenting with unilateral pulsatile tinnitus, otorrhoea, aural fullness, pruritis and hearing loss. Angiography was employed to exclude a glomus tumour and the patient underwent a modified radical mastoidectomy. Tissue samples confirmed a histological diagnosis of ISP of the middle ear...

OBJECTIVE: To examine preoperative risk factors, postoperative 30-day outcomes and adverse events of acute mastoiditis using a national pediatric surgical database. METHODS: We explored our objectives using a cross-sectional analysis of a hospital-based reporting system database.

Cholesteatoma is an ear disease based on a locally destructive noncancerous conglomerate of epidermis and keratin debris. Abnormal growth of stratified keratinized squamous epithelium in the temporal bone causes destruction of the outer and middle ear, potentially leading to hearing impairment, facial palsy, vertigo, lateral sinus thrombosis, and intracranial complications. Although cholesteatoma is effectively treated by surgical resection (mastoidectomy), the lack of effective and nonsurgical therapies potentially results in fatal consequences, establishing the need for a comprehensive investigation of cholesteatoma pathogenesis...

OBJECTIVE: To describe the practice of otology in America during the first quarter century of the American Otological Society (AOS). METHODS: Two sources were used to determine the most prevalent disease conditions cared for and surgical procedures undertaken during this era. All articles published in the AOS transactions between 1868 and 1893 were studied as were the otology textbooks published by 6 of the first 10 Presidents of the Society. RESULTS: The primary emphasis of late 19th century American otological scholarship was on chronic ear infection with numerous articles focusing on complications of otitis including frequent descriptions of fatalities...

BACKGROUND: Combined rocuronium and cisatracurium have synergistic effects. We investigated whether reduced doses are effective during coadministration, by monitoring neuromuscular relaxation during surgery. METHODS: This randomized, controlled clinical trial was registered at http://clinicaltrials.gov (registration number NCT02495038). The participants were 81 patients scheduled for elective mastoidectomy and tympanoplasty. Participants were assigned to groups, including the intubating dose group (Group I, n = 27; combined ED95 rocuronium and ED95 cisatracurium), the small reduction group (Group S, n = 27; dose reduced by 10% of each ED95), or the large reduction group (Group L, n = 27; dose reduced by 20% of each ED95)...

Attic cholesteatoma with antral extension in tight sclerotic mastoid cavities is a common presentation that creates difficult decision-making intraoperatively. Drilling through a sclerotic and small mastoid cavity, keeping the canal wall intactis often difficult and increases the risk of serious injury. Consequently, a canal-wall-down mastoidectomy is often performed. The endoscopic transcanal modified canal-wall-down mastoidectomy approach allows the benefits of an open cavity for cholesteatoma resection and the benefits of a closed cavity for better long-term care and a more normal ear canal and middle ear reconstruction...

INTRODUCTION: Cochlear implant (CI) electrode design impacts the clinical performance of patients. Stability and the occurrence of electrode array migration, which is the postoperative movement of the electrode array, were investigated using a mid-scalar electrode array and postoperative image analysis. METHODS: A prospective observational study was conducted. A mid-scalar electrode was surgically placed using a mastoidectomy, followed by a posterior tympanotomy and an extended round-window or cochleostomy insertion...
