    Kurzfassung: Computerized tomography and magnetic resonance imaging have now made it possible to reliably differentiate cholesteatoma from cholesterol granuloma of the petrous apex. The treatment for cholesteatoma is complete surgical excision when possible, whereas cholesterol granuloma needs only adequate drainage for control. A new transcanal infracochlear approach for drainage of cholesterol granuloma involving the anterior petrous apex is described. Absolute measurements from 10 cadaveric temporal bones were obtained to determine the distances between the cochlea, jugular bulb, carotid artery, and facial nerve. In all specimens the petrous apex was entered without invading the cochlea, carotid, or jugular bulb. Advantages of this technique include a more direct route to the petrous apex, dependent drainage, and preservation of the normal hearing mechanism, including the tympanic membrane. Clincial indications for this technique include failure of other treatment approaches and a high jugular bulb obstructing an infralabyrinthine approach. Experience to date shows that patients experience little difficulty from the procedure.

    Kurzfassung: A significant number of patients undergo Irradiation to the temporal bone for malignancies. Conflicting reports exist regarding the effects of irradiation on hearing thresholds. Although radiation‐induced otitis media and osteoradionecrosis of the ossicles with resultant conductive hearing loss are well‐documented, there is disagreement regarding the effect of irradiation on sensorineural hearing. Previous animal models, relying only on behavioral tests and reflex thresholds, have failed to reveal consistent threshold shifts after irradiation. However, with the advent of auditory brainstem response (ABR) testing, a reliable objective measurement of hearing in animals is available. Hearing thresholds were determined bilaterally by ABR testing in 21 albino guinea pigs. The left temporal bones of sixteen animals were then Irradiated with a total dose ranging from 5750 to 7000 cGy over 7 weeks. The right ears of these animals, plus both ears of five nonlrradlated guinea pigs, served as controls. Follow‐up threshold ABRs were obtained immediately post‐irradlation (RT), and at 6 and 12 months post‐RT. Average thresholds in all groups increased over time: 60 dB in the control group; 53 dB in the control ears of the Irradiated animals; and 46 dB in the Irradiated ears. There were no statistically significant increases in ABR thresholds for Irradiated ears vs. control ears. At the 6‐month followup, hearing was actually better in the Irradiated ears than the control ears and this difference between ears was significantly greater than the difference at baseline ( p 〈 0.026). Overall, there was no evidence that irradiation produces changes in ABR thresholds.

    Kurzfassung: When tympanosclerosis involves the tympanic membrane or the lateral ossicles, treatment is usually straightforward and uncomplicated. When the stapes is involved, therapy Is more controversial and may be more difficult. We report our results in 154 patients who underwent different surgical procedures for tympanosclerosis of the stapes. Followup was up to 10 years. Pure‐tone average threshold was significantly improved (P 〈 0.05) in patients who underwent mobilization procedures or stapedectomy for definitive treatment. The air‐bone gap was less than 20 dB at 6 months postoperative in 72% of patients and less than 30 dB in 90%. At 6 months, 2 years, and 5 years there were no statistically significant differences in hearing results between stapedectomy and mobilization patients, some of whom were followed for up to 10 years. No patient had a profound hearing loss after surgery. Surgical treatment for tympanosclerosis of the stapes is a safe procedure, with hearing results similar to those of surgery for other chronic ear diseases involving the ossicular chain.

    Kurzfassung: Vestibular schwannomas, also called acoustic neuromas, are benign tumors of the vestibulocochlear nerve. Patients with these tumours almost always present with signs of hearing loss, and many also experience tinnitus, vertigo, and equilibrium problems. Following diagnosis with contrast enhanced MRI, patients may choose to observe the tumour with subsequent scans or seek active treatment in the form of microsurgery, radiosurgery, or radiotherapy. Unfortunately, definitive guidelines for treating vestibular schwannomas are lacking, because of insufficient evidence comparing the outcomes of therapeutic modalities. We present a contemporary case report, describing the finding of a vestibular schwannoma in a patient who presented with dizziness and a "clicking" sensation in the ear, but no hearing deficit. Audible clicking is a symptom that, to our knowledge, has not been associated with vestibular schwannoma in the literature. We discuss the diagnosis and patient's decision-making process, which led to treatment with Gamma Knife radiosurgery. Treatment resulted in an excellent radiographic response and complete hearing preservation. This case highlights an atypical presentation of vestibular schwannoma, associated with audible "clicks" and normal hearing. We also provide a concise review of the available literature on modern vestibular schwannoma treatment, which may be useful in guiding treatment decisions.

    Kurzfassung: Since Guild first discovered glomus bodies in the middle ear, the diagnostic evaluation and therapy of glomus tympanicum tumors have remained challenging. This study describes 73 cases diagnosed as glomus tympanicum tumors over the past 30 years. During this period, imaging techniques have markedly improved, and surgical approaches have evolved and been refined. These 73 cases were reviewed from a clinical perspective involving presentation, diagnostic evaluation, and therapeutic management. Pulsatile tinnitus was the primary symptom in over half the patients, followed by hearing loss in one third. The physical exam rarely revealed a circumferential view of the lesion, emphasizing the necessity of further diagnostic evaluation. High‐resolution computerized tomography (CT) is currently the radiographic study of choice. A transmastoid surgical approach with extended facial recess was most commonly employed. Extension to the jugular bulb or internal carotid was rare, and no intraoperative complications of catecholamine secretion were noted. Postoperative complications were few, and the overall residual/recurrence rate was less than 5%. Additional clinical insights may assist in the management of these rare but fascinating tumors.

    Kurzfassung: Otosclerosis presenting in children and adolescents is uncommon. Typically, otosclerosis presents as a slowly progressive conductive hearing loss in the third to fourth decade. Many well‐documented studies have demonstrated excellent long‐term hearing results with stapedectomy. Although stapedectomy is highly effective, the rare complications may be devastating. Thirty‐one patients, 21 years or younger, underwent 40 stapedectomies for otosclerosis at our institution. The average age at surgery was 16 years, with a range of 7 to 21 years. Postoperative results showed an average improvement in air‐bone gap of 22 dB. Clinical and audiologic data were collected over a mean follow‐up period of 25 years. There was no statistically significant difference in air‐bone gap when comparing the immediate postoperative gap (measured 2 months after stapedectomy) with the last gap recorded (mean, 25 years after stapedectomy). Fifty percent of the ears operated on maintained an air‐bone gap within 10 dB at the last follow‐up, and an additional 40% maintained a 10‐ to 20‐dB gap. There were no significant relationships between demographic or clinical factors and “success” (gap ≤ 10 dB) or long‐term gap closure. Our data demonstrate that stapedectomy is an effective method for closing the air‐bone gap in children and adolescents with otosclerosis, and long‐term results parallel those of adults, showing maintenance of excellent gap closure. This review represents the largest population with the longest follow‐up in children who underwent stapedectomy for the treatment of otosclerosis.
