HYPOTHESIS We designed a study to determine the role of mastoid mucosal biofilm in chronic otitis media (COM). BACKGROUND Biofilm formation has been found in several chronic airway infections. COM is associated with chronic, recalcitrant infection of the mastoid mucosa, and surgery often is required. METHODS COM patients were divided into 2 groups: one with chronic suppurative otitis media ...

A previously described technique putatively differentiates short-latency auditory evoked potentials in peripheral and central neural pathways of the mouse and rat [Galbraith G, Waschek J, Armstrong B, Edmond J, Lopez I, Liu W, et al. Murine auditory brainstem evoked response: putative two-channel differentiation of peripheral and central neural pathways. J Neurosci Methods 2006;153:214-20]. Thi...

Introduction It is widely accepted that cholesteatoma almost invariably requires surgical management. There has been ongoing debate regarding the optimal technique since intact canal wall or canal wall up (CWU) mastoidectomy was developed in the decade following the widespread introduction of the operating microscope in 1953. At the time of the national comparative audit of mastoid surgery over...

BACKGROUND Mastoid abscess remains a recognised complication of otitis media despite the advent of antibiotics. The objectives of this study were to describe the risk factors in patients with mastoid abscess following acute and chronic otitis media and discuss the management of this infection. METHOD A retrospective analysis was done on all patients who underwent mastoidectomy for mastoid abs...

BACKGROUND I designed a percutaneous mastoid vent to provide permanent ventilation to the middle ear. The vent consists of an outer titanium tube that osseointegrates with the mastoid bone and an inner Teflon tube that protrudes into the mastoid antrum. OBJECTIVE To follow up all patients who had the mastoid vent inserted since 1995. STUDY DESIGN AND SETTING Retrospective study of 14 patien...

The aims of surgical treatment for cholesteatoma include complete removal of disease and formation of a dry, self cleaning ear in addition to hearing reconstruction. This presentation concentrates on techniques of open mastoid surgery or modified radical mastoidectomy to achieve a well-constructed cavity. This study analyzes both primary and revision mastoid surgery referred to the author. ...

BACKGROUND AND OBJECTIVES The purpose of the study was to compare the mastoid air-cell volume of the patients with superior semicircular canal dehiscence syndrome (SCDS) and that of the control patients with otosclerosis and temporal bone (TB) fracture. SUBJECTS AND METHODS Ten patients with SCDS were enrolled and 10 patients with bilateral otosclerosis and TB fracture were selected as contro...

OBJECTIVE To evaluate the cutaneous and the inner ear tolerance of bioactive glass S53P4 when used in the mastoid and epitympanic obliteration for chronic otitis surgery. MATERIAL AND METHODS Forty-one cases have been included in this prospective study. Cutaneous tolerance was clinically evaluated 1 week, 1 month, and 3 months after surgery with a physical examination of the retroauricular an...

BACKGROUND Postauricular cutaneous mastoid fistula (PCMF) is a rare complication of chronic suppurative otitis media, may also complicate ear surgery and, very rarely, has been reported to complicate congenital cholesteatoma. Few authors have given descriptions of techniques of closure, with majority agreeing on the difficulty in managing such fistula due to the necrotic nature of the margin. ...
