1/20. Spontaneous cerebrospinal fluid leakage and middle ear encephalocele in seven patients.Isolated cases of spontaneous cerebrospinal fluid (CSF) leakage with and without middle ear encephalocele have been reported. These leaks are usually accompanied by episodes of recurrent meningitis, hearing loss, or chronic headache. In this article, we report seven new cases of spontaneous CSF leakage. Six of these patients had conductive hearing loss and serous otitis media, and three had recurrent meningitis. Prior to a definitive diagnosis, six patients had received myringotomy tubes, which produced profuse clear otorrhea. Three patients had positive beta-2 transferrin assays. Computed tomography and magnetic resonance imaging confirmed a defect in the temporal bone tegmen. A combined transmastoid and middle fossa surgical approach with a three-layer closure was used to repair the tegmen defect. All patients had a lumbar drain placed prior to surgery. In addition to describing the seven new cases, we review the history of CSF leakage and discuss diagnostic methods, surgical findings, and our recommendations for management.- - - - - - - - - - ranking = 1keywords = otitis (Clic here for more details about this article) |
2/20. 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 = 1keywords = otitis (Clic here for more details about this article) |
3/20. Mucoepidermoid carcinoma arising from the eustachian tube and middle ear.We report a case of mucoepidermoid carcinoma (MEC) originating from the eustachian tube and middle ear. A 31-year-old male who presented with otorrhoea and methicillin-resistant staphylococcus aureus (MRSA) in the right ear was admitted to hospital due to cerebral infarction and deep vein thrombosis. After recovery, biopsies from a granulomatous mass found in the middle ear during operation for chronic otitis media revealed intermediate-grade MEC and a nasopharyngeal mass identified after surgery also revealed the same result. He received combined radiation therapy and chemotherapy and no residual or recurrent tumour was detected after two years of follow-up.- - - - - - - - - - ranking = 1keywords = otitis (Clic here for more details about this article) |
4/20. Neuroepithelial cysts of the middle ear.Neuroepithelial cysts are lesions of the central nervous system that have previously been reported in cerebral parenchyma, in the spinal cord, and within the ventricles in association with the choroid plexus. We describe 2 cases of neuroepithelial cysts of the middle ear. One was diagnosed after surgery for a retraction pocket and chronic otitis media complicated by an intraoperative cerebrospinal fluid (CSF) leak. The other produced bilateral spontaneous CSF otorrhea and mimicked the presentation of arachnoid granulations. Both cases were verified with immunohistochemical stains. Neuroepithelial cysts, although rare, should be considered in the differential diagnosis of spontaneous CSF otorrhea or an epitympanic mass.- - - - - - - - - - ranking = 1keywords = otitis (Clic here for more details about this article) |
5/20. Overlay versus underlay tympanoplasty. comparative study of 122 cases.INTRODUCTION: In tympanoplasty, the most common two techniques for positioning the graft relative to the remnant of both the tympanic membrane and of the annulus, are the "overlay" and the "underlay" techniques. Each technique has advantages and disadvantages. methods: One hundred and twenty-two cases over the age of 8 years who had undergone a tympanoplasty for tympanic membrane perforation secondary to chronic otitis media were included. All patients had a minimum 3-month postoperative otoscopic and audiometric follow-up. RESULTS: of 122 cases, 115 tympanoplasties (94%) were anatomically successful. At frequencies of 0.5, 1, 2, and 4 kHz, the mean air-bone gap improved significantly from 21.7 dB preoperatively to 8.4 dB postoperatively giving a mean gain of 13.3 dB. CONCLUSION: In our series the underlay or overlay positioning of the graft does not significantly influence the rate of postoperative perforations or complications with the exception of epithelial pearls, which occur significantly more frequently following the overlay technique for perforations that require fibro-epidermal cleaving across a large area.- - - - - - - - - - ranking = 1keywords = otitis (Clic here for more details about this article) |
6/20. Bilateral spontaneous cerebrospinal fluid otorrhea.We present a rare case of bilateral cerebrospinal fluid (CSF) otorrhea via multiple bony defects in the left tegmen and a single defect with the herniated brain tissue on the right side. Initially, the patient complained of left hearing loss and fullness and was diagnosed with serous otitis media. After myringotomy, the pulsating watery discharge suggested CSF otorrhea. Five months after surgical repair of the left side, right-side CSF leakage occurred. The right side was repaired surgically, and the patient recovered without incident. From our findings and a review of the literature, we postulate that bilateral CSF otorrhea resulted mainly from the thinness of the tegmen because of well-pneumatized mastoid air cells and the weakness of the dura after chronic inflammatory changes. In case of spontaneous CSF otorrhea, the roof of tegmen should be assessed bilaterally with care using radiologic examinations so as not to overlook a subclinical condition on the contralateral side.- - - - - - - - - - ranking = 1keywords = otitis (Clic here for more details about this article) |
7/20. Recurrent acute otitis media associated meningitis in a patient with a contralateral cochlear implant and bilateral cochleovestibular dysplasia.OBJECTIVE: To illustrate that a patient with a cochlear implant may be at increased risk of meningitis secondary to developmental anatomic abnormality associated with the underlying sensorineural hearing loss, as opposed to the implant itself. methods: Case report. RESULTS: Our 12-year-old patient has bilateral cochlear dysplasia, profound sensorineural hearing loss and no prior history of recurrent acute otitis media or meningitis. He underwent a left cochlear implant at 8 years of age and subsequently experienced three episodes of right acute otitis media and meningitis over the next 4 years. Middle ear exploration revealed a cerebrospinal fluid leak. A right radical mastoidectomy with closure of the external auditory canal, removal of the tympanic membrane, malleus, and incus, closure of the eustachian tube, and obliteration of the mastoid and middle ear with abdominal fat has prevented further episodes. CONCLUSION: meningitis in a patient with a cochlear implant is not necessarily related to the implant.- - - - - - - - - - ranking = 6keywords = otitis (Clic here for more details about this article) |
8/20. Gradenigo syndrome: a case report and review of a rare complication of otitis media.otitis media is a commonly seen condition in the Emergency Department. The complications of otitis media that were seen frequently in the preantibiotic era are now rare today. We report a case of a diabetic man who presented with otorrhea, retro-orbital pain, and diplopia secondary to a sixth cranial nerve palsy--Gradenigo syndrome. This syndrome occurs as infection from the middle ear spreads medially to the petrous portion of the temporal bone. The emergency physician should consider this condition in patients with chronic ear drainage or pain not responsive to conventional treatment or in any patient with a cranial nerve palsy in the setting of acute or chronic otitis. work-up should include a CT scan of the temporal bones. otolaryngology consultation and admission for i.v. antibiotics is recommended.- - - - - - - - - - ranking = 6keywords = otitis (Clic here for more details about this article) |
9/20. Congenital middle ear encephalocele initially seen with facial paresis.Congenital middle ear encephalocele (CMEE) is a rare entity, previously reported in only 29 patients. It might originate from dehiscence of the tegmen tympani or antri or the bony plate of the posterior fossa. The common presenting symptoms are spontaneous cerebrospinal fluid (CSF) otorrhea and/or rhinorrhea, persistent "serious otitis media," conductive hearing loss, and, occasionally, recurrent meningitis. We report a case of CMEE initially seen with progressive facial paresis, review the previously reported cases of CMEE, and discuss the pathogenesis and surgical management.- - - - - - - - - - ranking = 1keywords = otitis (Clic here for more details about this article) |
10/20. cerebrospinal fluid otorrhea at myringotomy. A meningocele through a defect in the tegmen.Spontaneous cerebrospinal fistulae can simulate secretory otitis media or be discovered at myringotomy, but the diagnosis is frequently made after one or more episodes of meningitis. Congenital perilabyrinthine fistulae are extremely rare, and unlike translabyrinthine fistulae there is usually no sensorineural hearing loss. This is the first reported case of a congenital meningocele through the tegmen in a child. An 11-year-old boy presented with signs and symptoms which mimicked serous otitis media. A cerebrospinal fistula was produced at myringotomy and this was closed surgically via an endaural approach. A CT scan defined a defect in the tegmen tympani anterior to the superior semicircular canal.- - - - - - - - - - ranking = 2keywords = otitis (Clic here for more details about this article) |
