BACKGROUND Mastoiditis is a known cause of lateral venous sinus thrombosis (LST). We have encountered patients with LST associated with mastoid abnormality on MRI without any clinical signs of infection; the significance of these abnormalities is uncertain. This study examines the relationship of LST and mastoid air sinus abnormalities systematically. SUMMARY OF REPORT We performed a retrospe...

Congenital cholesteatoma(CC) accounts for 25% of all cholesteatomas[1] most common site being middle ear. We report an extremely rare case of congenital cholesteatoma isolated to the mastoid process, with no middle ear involvement. An 18 year old male presented with ear ache and minimal discharge for 4 months. On examination, external auditory canal was found narrowed with granulations and bony...

Prenatal imaging of the fetal cerebellar vermis is challenging even for experienced examiners. We found that by aiming the ultrasound beam through the mastoid fontanel and then rotating the data set in a multiplanar reconstruction and applying volume contrast imaging in the C plane, we were consistently able to obtain images of the vermis in the standard midsagittal plane. Images of the fetal v...

OBJECTIVE To compare the auricular projection results across 3 different techniques of sulcus construction in microtia repair (using a temporoparietal fascial flap, a retroauricular fascial flap from the mastoid region, or a superficial muscular aponeurotic system advancement flap). METHODS All the patients had been photographed at least 3 months after the second stage (construction of the re...

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 ...

Aim: Facial reconstruction is a method that estimates the face shape of unidentified person using clay and similar material in cases where only skull present. Due to natural events animals, integrity skeletal remains can be disrupted this makes identification hard. The aim study estimate by reference mastoid process case fragmentation at scene. Material Methods: In study, computerized tomograph...

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...

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...
