Christina Mishu, David A Klodd, Miriam Redleaf
Exposure of the cochlear implant electrode array as a late complication has been reported rarely in the literature. A retrospective analysis revealed 4 patients presenting with exposure of their cochlear implant electrode arrays from 2 to 17 years after implantation. Data collected from these 4 patients were surgical implantation approach, type of implant, age at implant, interval between implant and complication, surgical correction of the problem, pathology at the time of correction, and length of follow-up after intervention...

Chronic otitis media (COM) is a common clinical entity, but the incidence of COM complications has declined recently due to broad use of antibiotics. Independent of this, these complications are still a significant challenge in otorhinolaryngology practice because of high morbidity and mortality rates. The most common etiologic diagnosis was cholesteatomatous COM. Simultaneous coexistence of complications of COM in the same case is a rare situation, and the present report describes a case with mastoiditis, Bezold abscess, lateral sinus thrombophlebitis, meningitis, and paraspinal abscess...

OBJECTIVE: We aimed to analyze preoperative and intraoperative clinical characteristics of chronic perforated otitis media by patient age. MATERIALS AND METHODS: We analyzed 137 tympanoplasties for chronic perforated otitis media in 133 patients. Exclusion criteria were ear adhesions, cholesteatoma, and a history of tympanoplasty. Patients were divided into a younger group (aged 15-39 years), a middle group (40-64 years), and an elderly group (≥65 years). We compared tympanoplasty technique (using Wullstein classification), mastoid air-cell area measured by temporal bone computed tomography, preoperative aeration of the temporal bone, mean preoperative hearing (at 500 Hz, 1000 Hz, and 2000 Hz), and patch effect calculated by the pre- and post-patch air-bone gap at frequencies of 250 Hz and 500 Hz among the three age groups...

PURPOSE: There are no formal radiologic criteria to stratify patients for transcanal (TEES) or transmastoid endoscopic ear surgery for resection of cholesteatoma. We aim to determine 1) whether standard preoperative computed tomography (CT) findings are associated with the need for conversion to a transmastoid approach and 2) the amount of time added for conversion from TEES to transmastoid techniques. MATERIALS AND METHODS: Retrospective chart review of consecutive pediatric and adult cases of TEES for primary cholesteatoma from 2013 through 2015 (n=52)...

Background and purpose The facial nerve is unique among cranial nerves in demonstrating normal enhancement of particular segments. The effect of varying T1 relaxivities of gadolinium-based contrast agents on facial nerve enhancement is unclear. In this study, we assess differences in normal facial nerve enhancement with two different gadolinium-based contrast agents, gadobutrol and gadopentetate dimeglumine. In addition, we evaluate differences in facial nerve enhancement with spin-echo (SE) T1 versus 3D inversion recovery prepared fast spoiled gradient-echo (FSPGR) post-contrast sequences...

OBJECTIVE: Cultures obtained from pre-operative middle-ear swabs from patients with chronic otitis media have traditionally been used to guide antibiotic selection. This study investigated changes in the bacterial strains of the middle ear during chronic otitis media surgery. METHODS: Pre-operative bacterial cultures of otorrhoea, and peri-operative cultures of the granulation tissue in either the middle ear or mastoid cavity, were obtained. Post-operative cultures were selectively obtained when otorrhoea developed after surgery...

INTRODUCTION: Ectopic cervical thymus (ECT) is a rare embryological abnormality in children. It can be revealed by a compressive neck mass mistaken for a malignant tumor. Through a new case of ECT, we review the embryopathogenesis, diagnostic difficulties and therapeutic features. CLINICAL OBSERVATION: A 19-month-old girl presented a right cervical mass that quickly increased in size, causing intermittent dyspnea. The physical examination objectified a 6-cm, soft and compressible, painless right cervical tumefaction, extending from the mastoid area to the ipsilateral supraclavicular fossa...

BACKGROUND: Cryptotia is a common congenital ear deformity in Asian populations. In cryptotia, a portion of the upper ear is hidden and fixed in a pocket of the skin of the mastoid. Here we describe our method for cryptotia correction by using an ultra-delicate split-thickness skin graft in continuity with a full-thickness skin rotation flap. PATIENTS AND METHODS: We developed a new method for correcting cryptotia by using an ultra-delicate split-thickness skin graft in continuity with a full-thickness skin rotation flap...

BACKGROUND: Pneumococcal conjugate vaccine (PCV) was introduced in 2000. The first 7-valent vaccine was followed by a 13-valent vaccine (PCV13) with the same conjugate, and a 10-valent vaccine (PCV10), conjugated to protein D from H. influenzae. The vaccines offer some protection against pneumococcal acute otitis media (AOM), and, with PCV10, possibly also some protection against H. influenzae AOM. PCV7 was introduced in Sweden in 2009, but from 2010, Swedish counties were free to use either PCV13 or PCV10...

While infrequent, cerebrospinal fluid (CSF) leaks are known to occur after surgical resection of vestibular schwannomas. Early signs of CSF leak often include headache and altered mental status. If untreated, life-threatening complications can occur, including brainstem herniation and meningitis. The appropriate surgical treatment for a CSF leak requires accurate localization of the source. While the most likely location of a CSF leak after lateral skull base surgery is through the aerated portions of the temporal bone, we present a unique case of a man with a prolonged CSF leak after an acoustic tumor removal who was ultimately found to have an occult spinal perineural (Tarlov) cyst as the source...

Lagochilascariasis is a parasitic disease caused by a helminth of the order Ascaroidea, genus Lagochilascaris that comprises 6 species, among which only Lagochilascaris minor Leiper, 1909, is implicated in the human form of the disease. It is remarkable that the majority of cases of human lagochilascariasis in the Americas have been reported in Brazil. The natural definitive hosts of this parasite seem to be wild felines and canines. Lagochilascariasis is mostly a chronic human disease that can persist for several years, in which the parasite burrows into the subcutaneous tissues of the neck, paranasal sinuses, and mastoid...
