Hydroxyapatite granules used in the obliteration of mastoid cavities in rats.
UNLABELLED Prospective experimental study in which we created a bony defect in the mastoids of rats and filled it up with hydroxyapatite to evaluate bone regeneration, to solve the problems of open cavities after mastoidectomies that frequently present with otorrhea, infection, granulation tissue and hearing loss. OBJECTIVE The aim was to evaluate bone regeneration in defects created in the m...
متن کاملNano-hydroxyapatite/poly -caprolactone composite 3D scaffolds for mastoid obliteration
The aim of this study is to evaluate the use of our nano-HA/PCL composite 3D scaffolds as graft materials for mastoid cavity obliteration in an animal model. Nano-HA particles were synthesized by chemical precipitation technique and mixed them with PCL solution to make composite paste. 3D scaffolds were fabricated by a paste extruding deposition process. The nano-HA/PCL 3D scaffolds showed good...
متن کاملMastoid Cavity Obliteration with Combined Palva Flap and Bone pâté
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...
متن کاملTotal mastoid obliteration in staged canal-up tympanoplasty for cholesteatoma facilitates tympanic aeration.
OBJECTIVE To assess middle ear aeration after total mastoid obliteration using bone pate and hydroxyapatite performed at the second stage of intact-canal-wall (ICW) tympanoplasty. STUDY DESIGN Retrospective study. SETTING Tertiary referral hospital. PATIENTS Forty-two ears with cholesteatoma underwent the obliteration. Computed tomography (CT) scan 1 week before the second-stage operation...
