    OBJECTIVES/HYPOTHESIS: Mastoidectomy has long been identified as an effective method of treatment for chronic ear infection. The effect of mastoidectomy on patients without evidence of active infectious disease remains highly debated and unproven. The objective in the study was to examine the impact of mastoidectomy on the repair of uncomplicated tympanic membrane perforations.

    STUDY DESIGN: Retrospective study of patients at tertiary referral center.

    METHODS: Four hundred eighty-four ...

    OBJECTIVE: To determine the incidence of bilateral endolymphatic sac tumors in von Hippel-Lindau syndrome and to describe the technique and results of hearing preservation surgery for small endolymphatic sac tumors in a series of patients with von Hippel-Lindau syndrome.

    STUDY DESIGN: Analysis of the literature to determine the incidence of bilateral endolymphatic sac tumors and a retrospective case review of hearing preservation surgery for removal of small endolymphatic sac tumors in ...

    OBJECTIVE: The age of modern microsurgery has made resection of glomus tumors with extensive skull base involvement possible. Resection of extensive lesions is not without risk of major complication or new cranial nerve deficit. Because glomus tumors are rare and slow growing, data reflecting recurrence risk after resection using modern skull base techniques are lacking. These factors complicate the accurate definition of efficacy of surgical resection and its functional cost. The object ...

    OBJECTIVES/HYPOTHESIS: To report the preliminary results of the Ototronix MAXUM middle ear implant for treatment of severe high-frequency sensorineural hearing loss.

    STUDY DESIGN: Case series with chart review.

    METHODS: Six consecutive ears with severe high-frequency sensorineural hearing loss (≥75 dB HL at 2, 3, and 4 kHz) and poor aided word recognition performance (≤60% single words) underwent implantation of the MAXUM system at a single, private otologic referral center. Primary ...

    Contemporary otomicrosurgical techniques have made total removal of acoustic tumor with preservation of the seventh and sometimes the eighth cranial nerves possible. The four approaches currently used in acoustic tumor surgery are the middle cranial fossa, the translabyrinthine, the suboccipital, and the combined translabyrinthine-suboccipital. This review examines the surgical results in the removal of more than 600 acoustic tumors and outlines a rationale for the choice of approach. ...

    Glomus tumors can be classified as to their origin in the temporal bone. Those limited to the middle ear and mastoid are referred to as tympanicum tumors while those originating in the jugular bulb are known as jugulare tumors. Diagnostic studies such as polytomes of the temporal bone, retrograde venograms and arteriograms now make it possible for the surgeon to determine not only the origin of the tumor but also the extent of its involvement in the temporal bone and base of the ...

    Giant-cell tumor of bone rarely occurs in the skull. There have been only 14 previously reported benign tumors involving the sphenoid and only 11 found in the temporal bone. While considered benign tumors, they are very aggressive and have a tendency to local recurrence and late malignant change with metastasis. These tumors are predominant in females and occur in the second and third decade of life.

    Treatment is usually with curettage and/or radiation. It is such a rare tumor that no ...

    OBJECTIVE: To better understand the characteristics and outcomes of facial nerve schwannomas (FNSs) over a 30-year period.

    STUDY DESIGN: Retrospective study.

    SETTING: Subspecialty practice at a tertiary hospital.

    PATIENTS: Fifty-six patients diagnosed with FNS over a 30-year period.

    METHODS: Preoperative data (audiologic data, facial nerve [FN] function, and patient symptoms), intraoperative data (tumor location, total versus subtotal resection, and FN status), and postoperative data ...

    Preservation of hearing was attempted in 161 cases of histologically confirmed acoustic neuroma removed by the senior author between January 1, 1970, and September 30, 1991. There were 136 patients with unilateral tumors; 22 patients had bilateral tumors (neurofibromatosis 2) and underwent a total of 25 procedures. Hearing was initially preserved in 35% of patients with unilateral tumors and in 44% of those with bilateral tumors. Results are reported in terms of pre- and postoperative ...

    Labyrinthectomy has been used for years in the surgical management of Menière's disease for the control of vertigo. The effect of this procedure are predictable and satisfying but residual hearing is sacrificed. With the advent of the middle fossa section of the vestibular nerve, it soon became apparent that it was possible to obtain relief from vertigo and at the same time preserve residual hearing. How do the two procedures actually compare as far as relief of vertigo, postsurgical ...

    Lesions of the cerebellopontine angle may cause a sudden hearing loss. To illustrate and reaffirm the importance of a thorough neurotologic evaluation we performed a retrospective review of the audiologic and clinical data available on 506 patients with proven lesions of the cerebellopontine angle. Seventy-seven patients (15.2%) were found to have a history commensurate with sudden hearing loss. We reviewed the relevant audiologic data as well as the clinical circumstances of this select ...
