Backgrounds and Objectives:Recently congenital cholesteatoma of middle ear has been diagnosed in earlier stage and its clinical manifestation has showed changed clinical manifestation, comparing that of reported literature. Aim of this study were to elucidate of clinical finding, extent of the cholesteatoma, staging, operative procedure and rate of postoperative recurrence in congenital middle ear cholesteatoma. Materials and Methods:47 cases of congenital cholesteatoma had been treated in Department of Otorhinolaryngolgy of Pusan National University Hospital from 1997 to October of 2010 and were reviewd retrospectively. Results:Congenital cholesteatoma showed male preponderance, and had diagnosed incidentaly (46.8%) and most common symptom was hearing loss. Most were found in tympanum only (70.2%) and more found in posterior portion than in anterior portion. Rate of each stage is similar distribution in stage I, II, III, IV. Recurrence rate showed 14.9%. Conclusions:Early diagnosis and early intervention is important to avoid recurrence and morbidity.
We report, with a review of literature, an unusual case of ossifying fibroma of temporal bone. A 34-year-old female with historyof left craniectomy for hemifacial spasm visited our department in 1998 because of an incidentally found temporal bone mass.Magnetic resonance imaging showed a well-circumscribed, lobulated 333 cm sized tumor mass which was localized in thetemporal bone but did not invade the middle and inner ear with high signal intensity at T2 weighted image. The patient did nothave the spasm until 2000, when she manifested intermittent right otalgia. A computed tomography scan showed the 333cm sized right temporal bone tumor with bony erosion including tegmen mastoid and partial bony destruction. After retroauricularincision, tumor and granulation tissue were removed through simple mastoidectomy. The permanent pathologic report confirmedthe diagnosis of ossifying fibroma. The patient returned in August of 2004 with recurrent right otalgia that had been therefor 3 months. A computed tomography scan showed lobulated, multiseptated, osteolytic, low density tumor which located in theupper portion of mastoid pyramidal base. She underwent a simple mastoidectomy with removal of the recurred ossifying fibromawith destruction in tegmen mastoid. Ossifying fibroma are rare lesions of the temporal bone. Because tumors progress and canbecome clinically massive, early complete resection is advised whenever feasible to prevent clinically evident recurrences andpotentially life-threatening complication.
Cochlear implantations are very popularly performed for hearing rehabilitation of profound hearing loss recently. Postoperative dizziness is one of common complications of cochlear implantation, and one-third of recipients complaint of experience a dizziness after cochlear implantation. The patients should be informed about postimplantation vertigo symptoms. Aims of this article are to provide the basis for preoperative counseling, decrease of postoperative dizziness and postoperative vestibular therapy to cochlear implant recipients with literature review.
Pulsatile tinnius has caused multiple etiology, vascular or nonvascular origin. Most patients of pulsatile tinnitus are treatable with correct diagnosis. So evaluation including history taking, audiometry, auscultation and radiologic study with angiography is very important. Authors had reviewed incidence, etiology, evaluation, and management of the pulsatile tinnitus by literature.
