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...

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. ...

introduction: this study was designed to evaluate the usefulness of mastoid cavity obliteration with combined bone pâté and palva flap in the prevention of problematic mastoid cavities after canal wall down mastoidectomy.   materials and methods: in a prospective longitudinal study with a mean follow-up of 28 months conducted between 2008–2012, a series of 56 ears in 48 patients with chronic ot...

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...

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. ...

An osteoma of the temporal bone is a rare benign tumor. External auditory canal is the most common site of osteomas arising from temporal bone, and mastoid osteoma is very rare. A case of a 42-year-old female with a huge osteoma which developed from mastoid cortical bone is presented and the review of the temporal bone osteomas is discussed. The patient showed a huge and hard mass in the right ...

BACKGROUND Advanced parotid cancers more than 4 cm are firmly fixed around the main trunk of the facial nerve that can be hardly detected in narrow working space between mastoid process and parotid cancer. Even though facial nerve was preserved, facial nerve stretching during surgery has significantly serious effect on postoperative facial palsy. OBJECTIVE To evaluate usefulness of removing m...
