1/16. Salivary gland choristoma of the middle ear: a case report.A choristoma is a nonneoplastic proliferation of histologically normal tissue that forms at an abnormal site. It is extremely uncommon in the middle ear space. It appears to be a developmental abnormality and may be associated with abnormalities of adjacent structures. It usually occurs with unilateral conductive hearing loss and requires a differential diagnosis from other mass lesions in the middle ear cavity. This article discusses a case of salivary gland choristoma of the middle ear that we believe to be the 24th case reported on this subject.- - - - - - - - - - ranking = 1keywords = hearing loss, hearing (Clic here for more details about this article) |
2/16. Labyrinthine fistula detection: the predictive value of vestibular symptoms and computerized tomography.A retrospective case record study of 20 patients in Oslo operated on for chronic otitis media with labyrinthine fistula between 1986 and 1999 was performed in order to estimate the incidence of, and identify predictors for, labyrinthine fistulas. The incidence of fistula was 0.3 per 100 000, with a median age at diagnosis of 37 years. The median duration of chronic otitis media prior to labyrinthine fistula detection was significantly correlated with age at surgery. Subjective hearing loss (90%), otorrhoea (65%) and dizziness (50%) were presenting symptoms. Modified canal-wall-down mastoidectomy was performed in all patients. Preoperative hearing levels could not predict postoperative hearing outcome. Positive signs of fistula were found in only 4 patients (20%). Correspondingly, computerized tomography (CT) diagnosed the fistula in 11 patients (55%). The seven patients presenting without dizziness and with a negative CT scan and fistula test were characterized by lower age, absence of previous middle ear surgery, lower preoperative pure-tone thresholds for bone conduction and better hearing outcome after surgery. In conclusion, the identification of a younger group of patients presenting with fewer symptoms indicates that fistulas should be suspected in all patients undergoing surgery for chronic middle ear and mastoid disease.- - - - - - - - - - ranking = 2.0708412081901keywords = hearing loss, hearing (Clic here for more details about this article) |
3/16. 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 = 0.35694706939669keywords = hearing (Clic here for more details about this article) |
4/16. A case of tympanogenic labyrinthitis complicated by acute otitis media.Widespread use of antimicrobial drugs in the management of otitis media has significantly reduced the incidence of labyrinthitis nowadays. Cases of tympanogenic labyrinthitis following acute otitis media have rarely been reported in recent literature on otolaryngology. We report an unusual case of tympanogenic labyrinthitis that presented with sudden sensorineural hearing loss (SNHL) following acute otitis media in an adult who had no previous otological complaints. An audiogram revealed SNHL with pure tone threshold of 43.7 dB in the left ear. MRI was helpful to identify the inflammatory change of the membranous labyrinth. The patient's hearing returned to normal after treatment. The definite diagnosis of serous labyrinthitis was established retrospectively.- - - - - - - - - - ranking = 2.3124485120985keywords = hearing loss, sensorineural hearing loss, hearing, sensorineural hearing, sensorineural (Clic here for more details about this article) |
5/16. Cerebral amyloidoma diagnosed intraoperatively with squash preparations: a case report.BACKGROUND: Amyloidoma (tumoral amyloidosis) is the rarest form of central nervous system (CNS) amyloidosis. CASE: A 51-year-old woman presented with recurrent right-sided otitis media and hearing loss. Computed tomography and magnetic resonance imaging revealed a mass in the right temporal lobe. Cytologic findings at the time of stereotactic biopsy for suspected glioma were compatible with amyloidoma. Subsequent histologic and electron microscopic findings confirmed the diagnosis of amyloidoma. Auxiliary testing ruled out systemic amyloidosis and plasma cell dyscrasia. CONCLUSION: To our knowledge, this is the first report on the cytologic findings in a case of CNS amyloidoma.- - - - - - - - - - ranking = 1keywords = hearing loss, hearing (Clic here for more details about this article) |
6/16. Primary tuberculous petrositis.Tuberculous osteomyelitis of the temporal bone is a rare and dangerous entity that should be included in the differential diagnosis of infectious processes of the base of the skull. We present the case of an 11-year-old child who presented with diplopia, ear discharge and hearing loss. The radiological and histopathological findings revealed tuberculous otitis with osteomyelitis and an abscess in the petrous apex. The child responded to anti-tuberculous chemotherapy. The diagnosis and management of tuberculous osteomyelitis are discussed and a brief review of the literature is presented.- - - - - - - - - - ranking = 1keywords = hearing loss, hearing (Clic here for more details about this article) |
7/16. Middle ear tuberculosis--a series of 24 patients.A study of 24 cases (25 ears) of tuberculous otitis media is revealed. Characteristic findings of the disease e.g. painless ottorhea and multiple perforations of the tympanic membrane, are not considered consistent with our findings of the clinical features of the pathology. Severe conductive hearing loss, abundant pale granulations and an eroded maleus handle consistently occurs in the pathology and in our opinion are more significant clinical features of the disease. As mixed infections are often present, histological examination of the granulation tissue from the middle ear and mastoid is the best diagnostic procedure. Treatment with anti-tuberculous therapy combined with surgery is shown to give good results.- - - - - - - - - - ranking = 1keywords = hearing loss, hearing (Clic here for more details about this article) |
8/16. hearing loss with delayed onset of vertigo.The association between the delayed onset of episodic true vertigo and previous sensorineural hearing loss has been previously described. We have reviewed our series of sixty consecutive labyrinthectomies to determine the prevalence of this disorder in this population, and found a variety of etiologic agents of sensorineural hearing loss with subsequent delayed vertigo. Relief from vertigo following surgery has confirmed that the previously deafened ear has been the cause of the vertigo. Case histories are presented and the literature is reviewed.- - - - - - - - - - ranking = 3.9110028854036keywords = hearing loss, sensorineural hearing loss, hearing, sensorineural hearing, sensorineural (Clic here for more details about this article) |
9/16. Surgical obliteration of the tympanomastoid compartment and external auditory canal.The ideal patient for a radical mastoidectomy with total tympanomastoid cavity obliteration is one with chronic granulomatous otomastoiditis without cholesteatoma, profound sensorineural hearing loss, and a normal ear on the opposite side. A meticulous and thorough classical radical mastoidectomy is required. The resultant cavity is eliminated by filling it with pedicled flaps and/or adipose tissue taken from the abdominal wall. Suturing the skin of the anterior and posterior membranous canal walls completes the procedure. Healing is rapid and requires minimal postoperative care. The absence of a cavity eliminates the necessity of additional otologic care. swimming, diving, and free participation in all other aquatic sports are important additional benefits. This procedure has been performed in 44 patients, 24 by author HFS and 20 by author JRC.- - - - - - - - - - ranking = 1.9555014427018keywords = hearing loss, sensorineural hearing loss, hearing, sensorineural hearing, sensorineural (Clic here for more details about this article) |
10/16. Wegener's granulomatosis with otological and nervous system involvement.Wegener's granulomatosis usually presents to the otolaryngologist with nasal manifestations. Complications including otologic and central nervous system symptoms occur in 20-40 per cent of cases. Two such cases presented to our clinic with nasal manifestations initially, one subsequently developing otologic sequelae and one progressive sensory motor neuropathy. These patients were followed to determine the reversibility of the otologic and sensory motor neuropathy while on therapy. The otologic changes remain and this patient was required to use a hearing aid. The sensory motor neuropathy improved rapidly so that the other patient's ability to walk soon became normal but sensory deprivation continues below the ankle bilaterally. The literature concurs with findings that involvement of the central nervous system and special sense organs such as the cochlea have limited reversibility once they occur, and early detection, therapy, and prevention of such complications are most important.- - - - - - - - - - ranking = 0.35694706939669keywords = hearing (Clic here for more details about this article) |
