Introduction. Osteomas are a slow growing benign neoplasm of unknown etiology very rarely involving the temporal bone. They develop in the external auditory canal on squamous sections, in the mastoid, middle and inner ear. By bone composition they are divided into spongious (osteoma spongiosum) and compact osteomas (osteoma eburnum); by growth direction, into outward-growing (exosteoma) and in inwardgrowing (endosteoma); into unilateral and bilateral; by size, into small and gigantic; by surface structure, into smooth and multilobular; by number, into solitary and multiple; into symmetrical and asymmetrical. The symptoms of intracanalicular osteomas are the result of auditory canal obstruction. Diagnosis is made based on case history, clinical examination, audiological processing and radiography (temporal bone CT scan), and confirmed by histopathological examination of the bone. In terms of differential diagnosis, they must be distinguished from exostoses, bone tissue proliferation and osteoid osteomata. The progress of the disease is prolonged, as they are slow growing, asymptomatic and benign tumours. Therapy is surgical only. Case Outline. The report presents the case of a 70-year old patient with the osteoma of the right external auditory canal. In our patient, the osteoma arose in the auditory canal, the most frequent localization; it was unilateral, solitary, multilobular and compact. It was discovered accidentally, during otoscopic examination. The clinical diagnosis was confirmed by CT scan of the temporal bone. We applied surgical therapy by retroauricular approach. The removed bone change was about 12 mm high, 13-14 mm deep and about 8 mm wide. Histopathological findings confirmed osteoma. Conclusion. Due to their slow growth, the rate of auditory canal osteomas develop asymptomatically for a long time without the characteristic clinical features. In most cases, they are discovered accidentally during otoscopic or radiographic examination. The method of choice in diagnosis is temporal bone CT scan. Therapy is surgical.

<p>Stapediovestibular luxation by Q-tip ear injury is a rare occurrence. The traumatic context associated with cochleovestibular symptoms should lead to a high index of suspiscion. Temporal bone CT scan confirms the diagnosis. The authors report a case of stapediovestibular luxation and discuss the management of this condition. An 8-year-old boy presented to our department for otalgia, hearing loss, and dizziness. The history revealed a penetrating right ear injury by Q-tip, which had occurred 5 days previously. ENT examination found a right peripheral vestibular syndrome with ipsilateral tympanic perforation. Tonal audiometry noted right cophosis. Temporal bone CT scan showed right side internal stapediovestibular dislocation. Middle ear inspection with oval window fistula repair and tympanic closure were performed. Postoperative outcomes showed complete resolution of vestibular symptoms without  improvement of sensorineural hearing loss thresholds. Traumatic stapediovestibular dislocation by Q-tip ear injury is unusual. Early diagnosis, with precise lesion assessment and appropriate management resolve vestibular symptoms, prevent infectious complications. But, hearing outcomes are variable.</p><p> </p>

Background and Objectives: Chronic otitis media is considered a common disease in our region. There are various methods for evaluation of chronic suppurative otitis media including otoscopy, CT scan, X-ray, and MRI. Nowadays, computed tomography or CT scan is used as the selected method to investigate the temporal bone. This study aims to collect the intraoperative findings and compare them with preoperative reports of temporal bone CT scans. Materials and Methods: The patients’ data with chronic otitis media who were reviewed tomographically, hospitalized and operated between 2012 and 2014 in Tabriz Sina Hospital by only one otolarynologist included in this study collected. Results: The most common lesion based on the highest frequency and percentage is Tympanosclerosis. 21.4 percent of patients whom Tympanosclerosis were not diagnosed preoperatively, found during the surgery. 78.9 And 21.1 percent of bone erosions have been diagnosed by CT scan and by direct vision, respectively. Conclusion: Although preoperative CT of Middle ear lesions is useful for surgery planning but some lesion may not be completely diagnosed by CT scan and intraoperative assessment of surgical field is crucial.
