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 otit...

The complete nucleotide sequences of two bacteriocin-encoding plasmids isolated from Hafnia alvei (pAlvA and pAlvB) were determined. Both plasmids resemble ColE1-type replicons and carry mobilization genes, as well as colicin-like bacteriocin operons. These bacteriocins appear to be chimeras consisting of translocation domains from Tol-dependent colicins, unique binding domains, and killing and...

Introduction The paramount goal for subjects with sensory-neural hearing loss is to make as precise a distinction as possible among the different sites in the sensory system where a casual lesion may lie. The usual tests of conventional audiometry· viz., pure tone sensitivity measures; tests of recruitment and abnormal tone decay; Bekesy audiometry; speech audiometry; stapedius reflex measureme...

background and aims. wound dehiscence after lower third molar surgery extends the postoperative treatment period and may cause long-standing pain. the aim of this study was to compare wound dehiscence after removal of wisdom teeth in the most prevalent mandibular impaction (mesioangular class ib) by two different soft tissue flap designs. materials and methods. partially-erupted mandibular thir...
