1/18. cholesteatoma in a child with congenital ichthyosiform erythroderma.A 7-year-old girl had non-bullous congenital ichthyosiform erythroderma (NBCIE) in treatment with retinoids. She also suffered continuous desquamation of the external ears, recurrent external otitis, chronic adenoiditis, tubaric dysfunction and intermittent episodes of otitis media and developed a cholesteatoma in her left ear. Chronic scaling disorders, such as NBCIE and other ichthyosis, can be entities at risk for the development of cholesteatoma in childhood.- - - - - - - - - - ranking = 1keywords = otitis (Clic here for more details about this article) |
2/18. Organic change of effusion in the mastoid in otitis media with effusion and its relation to attic retraction.To try to solve the pathogenesis of severe attic retraction viewed from mastoid condition, we examined the residual soft tissue density (RSTD) in the mastoid by computed tomography (CT) in 85 patients (107 ears) with otitis media with effusion (OME) 3 months after tympanostomy tube insertion or later. The incidence of RSTD in the mastoid was significantly higher in OME of adults (52.6%) than in children (24.1%). Ears with severe attic retraction had RSTD significantly more frequently (80%) than those with no or mild attic retraction, and many of the mastoids with severe attic retraction were occupied totally by RSTD. The area of the mastoid (mastoid pneumatization) was significantly smaller, and CT density of the mastoid (sclerotic tendency) was significantly higher in ears with RSTD than in those without. RSTD after tympanostomy tube insertion in the mastoid indicating organic change of effusion was considered one of the important factors relating to the pathogenesis of severe attic retraction.- - - - - - - - - - ranking = 2.5keywords = otitis (Clic here for more details about this article) |
3/18. Mature teratoma of the middle ear.OBJECTIVE: The authors report a case of mature teratoma of the middle ear in a 3-year-old girl with a 1-year history of otitis media. methods AND RESULTS: Radiologic investigation revealed a partially cystic lesion of the petrous portion of the right temporal bone. It produced opacification of the middle ear as well as destruction of septal air cells. The patient underwent a subtotal petrosectomy. Histologically, the tumor was composed of an intimate admixture of mature tissues representing all three germ layers, including brain, myelinated nerve trunks, skeletal muscle, bone, immature cartilage, seromucinous glands, and respiratory epithelium. Of note within the brain tissue was choroid plexus within an ependyma-lined rudimentary ventricle. Immunohistochemical studies were also performed. Twenty months after surgery, the patient was well, with complete recovery from symptoms. CONCLUSION: Teratomas of the middle ear are rare neoplasms. Only a few examples have been reported. As a rule, they are cured by resection and do not require adjuvant therapy.- - - - - - - - - - ranking = 0.5keywords = otitis (Clic here for more details about this article) |
4/18. Congenital cholesteatoma of the tympanic membrane.We present two cases of congenital cholesteatoma of the tympanic membrane. Congenital cholesteatoma within the tympanic membrane is a rare entity with only few cases documented. The aetiopathogenesis of this lesion is still unknown. An embryologic origin is hypothesized when cholesteatoma develops in patients without previous history of otitis as in the two cases we report. In cases with previous history of inflammatory process of the external or middle ear an acquired origin is suspected due to the proliferation of the basal cell layer of the tympanic membrane epithelium. Despite the rarity of the congenital tympanic membrane cholesteatoma, we think that its early diagnosis is of utmost importance to allow an easy removal and avoid middle ear involvement.- - - - - - - - - - ranking = 0.5keywords = otitis (Clic here for more details about this article) |
5/18. Anterior subannular T-tube for prolonged middle ear ventilation during tympanoplasty: evaluation of efficacy and complications.OBJECTIVE: We previously described the use of anterior subannular T-tubes (n = 20) for long-term middle ear ventilation. In the current study, we examine a larger patient population (n = 38) and a longer follow-up interval (average >2 years) to evaluate the efficacy and safety of anterior subannular tympanostomy. STUDY DESIGN: Retrospective nonrandomized case review. SETTING: Tertiary referral hospital. patients: Our series consisted of 38 consecutive patients with a diagnosis of eustachian tube dysfunction, adhesive otitis media, or chronic otitis media with a perforation who underwent a tympanoplasty. INTERVENTION: A subannular T-tube was placed anteriorly at the time of tympanoplasty to provide long-term middle ear ventilation. MAIN OUTCOME MEASURES: The main outcomes of this study are tube position, tube patency, and middle ear ventilation. In addition, hearing was evaluated both preoperatively and postoperatively and any complications were noted. RESULTS: There were 38 patients and 38 ears that received an anterior subannular T-tube at the time of tympanoplasty. The study group consisted of 24 female patients and 14 male patents with a median age of 36 years (range, 10-75 yr). All 38 patients had eustachian tube dysfunction, 22 had adhesive otitis media, 23 had chronic otitis media, 13 had a cholesteatoma, 11 had tympanic membrane perforations, and 3 patients had a cleft palate. All patients underwent tympanoplasty. Eighteen patients had a concomitant ossiculoplasty and 7 had a mastoidectomy. Follow-up ranged from 1 month to 48 months (average, 26 mo). Three tubes had extruded within 2 years, in 1 case resulting in a persistent perforation. postoperative complications included 1 patient with a partially extruded prosthesis, 2 patients with tipped prosthesis and persistent tympanic membrane retraction, and 1 patient with a plugged tube. All other tubes were patent and showed no evidence of migration. Furthermore, there were no cases of anterior canal blunting or ingrowth of epithelium around the tube. CONCLUSION: Anterior subannular tympanostomy is a safe and effective method for long-term middle ear ventilation in patients with chronic eustachian tube dysfunction.- - - - - - - - - - ranking = 2keywords = otitis (Clic here for more details about this article) |
6/18. Ear involvement in ligneous conjunctivitis: a rarity or an under-diagnosed condition?conjunctivitis lignosa, a rare affliction of the conjunctiva, is sometimes associated with other disturbances. We present two children with concurrent conjunctivitis lignosa and ear involvement. In these two cases, there were histopathologically verified ligneous changes of the middle ears. Routine haematoxylin and eosin, van Gieson, periodic acid-Schiff (PAS) and alcian blue staining of specimens from the eyes and middle ears revealed findings typical for ligneous conjunctivitis. In addition, new histochemical and immunohistochemical studies for glycosaminoglycans on specimens from the eyes and middle ears showed that the accumulations of the amorphous, cell-deficient material stained strongly but heterogeneously for hyaluronic acid and weakly but uniformly for keratin sulphate. The staining for other glycosaminoglycans, e.g. chondroitin-4-sulphate and dermatan sulphate was confined to vessels and areas rich in collagen fibres and fibroblasts. In patients with conjunctivitis lignosa, the ear involvement may remain undiagnosed due to its resemblance to secretory otitis media with effusion. Since isolated ear involvement may occur, we advocate biopsies for routine haematoxylin and eosin, and specific staining for hyaluronic acid and keratin sulphate, also in children with protracted, refractory otitis media with atypical effusion.- - - - - - - - - - ranking = 1keywords = otitis (Clic here for more details about this article) |
7/18. Gas-containing otogenic brain abscess.BACKGROUND: Gas-containing brain abscesses are very rare. Two mechanisms may be responsible for the presence of intracavitary gas: bacterial fermentation or penetration through an abnormal communication between the exterior and the intracranium. The need to search for this potential communication is considered an indication for open surgery. We report the case of a surgically treated gas-containing brain abscess originating from an undiagnosed chronic otitis media. CASE DESCRIPTION: A 54-year-old man developed acute neurologic deterioration, becoming comatose within 24 hours. A contrast-enhanced computed tomography (CT) scan disclosed a gas-containing cystic mass in the right temporal lobe. Urgent surgical decompression revealed the presence of an abscess, which was excised. During the same surgery, we performed a radical mastoidectomy, removing a previously undiagnosed attic cholesteatoma. Neither procedure revealed a discontinuity of the floor of the middle cranial fossa. Cultures grew a mixed flora. Antibiotics were administered for 6 weeks. The patient made a complete neurologic recovery. CONCLUSION: This report demonstrates that otogenic brain abscesses may contain gas due to fermentation of nonclostridial bacteria.- - - - - - - - - - ranking = 0.5keywords = otitis (Clic here for more details about this article) |
8/18. External auditory canal closure in cochlear implant surgery.OBJECTIVE: To evaluate surgical techniques and complications associated with external auditory canal (EAC) closure in cochlear implant surgery. STUDY DESIGN: Retrospective case review. SETTING: Tertiary referral center with a large cochlear implant program. patients: Twenty-eight patients (8 adults and 20 children) underwent multichannel cochlear implantation with EAC closure. The follow-up periods ranged between 1 and 10 years. Closure of the EAC was performed in conjunction with implantation of ears with chronic suppurative otitis media or cochlear drill-out procedures for ossification, or for access to the cochlea in patients with abnormal temporal bone anatomy. A modified Rambo technique was used for EAC closure in all but one case. INTERVENTIONS: cochlear implantation with EAC closure and subsequent clinical and radiologic follow-up. MAIN OUTCOME MEASURES: postoperative complications or the development of cholesteatoma in the implanted ear. RESULTS: cholesteatoma developed in the implanted ear in two patients. Breakdown of EAC closure occurred in one of these patients. The details of these patients are reviewed. CONCLUSION: Closure of EAC can be done with relatively low risk. Close and careful follow-up is required for early detection of a developing cholesteatoma.- - - - - - - - - - ranking = 0.5keywords = otitis (Clic here for more details about this article) |
9/18. paraganglioma presenting as chronic otitis media with cholesteatoma: pitfalls and strategies.The coexistence of paraganglioma with cholesteatoma is a very rare clinical disorder. The clinical presentations are nonspecific. There may be radiological characteristics of either cholesteatoma or paraganglioma in the middle ear area, but the diagnosis of the coexistence of the 2 is usually made only postoperatively. Here is such a case that is made more interesting not only because it initially presented with conductive hearing loss but also because the clinical picture mimicked chronic otitis media. The patient underwent postauricular tympanomastoidectomy with extended facial recess approach to remove the tumor. No evidence of recurrence and complications were noted.- - - - - - - - - - ranking = 2.5keywords = otitis (Clic here for more details about this article) |
10/18. Middle ear carcinoma originating from a primary acquired cholesteatoma: a case report.OBJECTIVES: To describe middle ear carcinoma originating from the matrix of primary acquired cholesteatoma in a 43-year-old man and to discuss the relationship between middle ear carcinoma and cholesteatoma. STUDY DESIGN: Case report. SETTING: Department of otolaryngology, head and neck Surgery of Niigata University Medical and Dental Hospital, which is a tertiary care center, Niigata, japan. PATIENT: A 43-year-old man demonstrated symptoms resembling those of cholesteatoma: facial palsy, gradually progressive hearing loss, and chronic draining of the right ear. Other objective findings also supported a finding of cholesteatoma, but a computed tomographic scan and magnetic resonance imaging scan showed a well-enhanced mass and extensive bony erosion in the middle ear. At surgery, a granulous tumor in the mastoid cavity was diagnosed as squamous cell carcinoma, and closely coexisting cholesteatoma was found. Surgical specimen demonstrated carcinoma and cholesteatoma in the same field. INTERVENTION: radiation and chemotherapy were performed followed-up by mastoidectomy. CONCLUSION: Because middle ear carcinoma has a poor prognosis, it is important to detect lesions early. It is necessary to consider that middle ear carcinoma arises from not only chronic otitis media or surgical invasion but also from primary acquired cholesteatoma.- - - - - - - - - - ranking = 0.5keywords = otitis (Clic here for more details about this article) |
