    Chondrosarcoma of the nasal septum
    (Int Rhinologic Soc, 2000) Meric, F; Osma, U; Cüreoglu, S; Topçu, I; Aslan, A
    Chondrosarcoma of the nasal septum is a rather uncommon tumour. Therefore, only limited numbers of cases have been described in the literature. This paper reveals one more case observed at the ORL department of Dicle University. In the present case, by using a transnasal and transpalatal approach, total resection of the tumour was performed in conjunction with postoperative radiotherapy.

    The complications of chronic otitis media: report of 93 cases
    (Headley Brothers Ltd, 2000) Osma, U; Cureoglu, S; Hosoglu, S
    The aim of this study was to investigate the incidence, mortality and morbidity of complications due to chronic otitis media (COM). During the nine-year period 1990-1999, 2890 cases of COM were reviewed, 93 (3.22 per cent) having 57 (1.97 per cent) intracranial complications (IC) and 39 (1.35 per cent) extracranial complications (EC). In three patients more than one complication was observed. Meningitis and brain abscess were common in the IC group. Subperiosteal abscess (mastoid and Bezold's abscess) was a common complication in the EC group. Cholesteatoma and granulation/polyp in the middle ear/mastoid were the major findings in both groups. Fifteen patients died from IC. Overall, the mortality rate was 16.1 per cent in all patients having complications, and in patients with IC it was 26.3 per cent. In all of the patients with complications, the morbidity rate was 11.8 per cent. Our study supports the finding that meningitis and brain abscess are the common complications of COM and the main reason for mortality.

    Evaluation of brainstem auditory evoked response audiometry findings in children with tuberculous meningitis at admission
    (Elsevier Sci Ltd, 2002) Topcu, I; Cüreoglu, S; Yaramis, A; Tekin, M; Oktay, F; Osma, U; Meric, F
    Objective: To determine the characteristics of Brainstem auditory evoked response (BAER) findings in children with tuberculous meningitis (TBM) at admission. Methods: Twenty-seven children with highly probable TBM were admitted to the University Hospital. The control group was 23 healthy, age and sex matched subjects. Brainstem response audiometry recording was performed in all patients and controls. Ninety dB sound pressure level (SPL) was used for comparisons. The main BAER measurements analysed were the I-III, III-V, I-V interpeak intervals. In statistical analysis, t-test for independent groups were performed. At the same time, for interpeak intervals, values exceeding 2.5 standard deviations (S.D.) above the means of the normal controls were considered abnormal. To the result of BAER findings, HL was classified as mild (until 40 dBHL), severe (until 80 dBHL) and total HL (no hearing was detected). Results: The latencies of interpeak intervals (except III-V latency at 10 per s) have significantly prolonged in comparison with controls. Mild HL was detected in four cars. In eight ears, any wave form could not be obtained at 110 dBSPL. Abnormal BAER result was seen in 13 of 54 ears (24%) at the click of 10 per s and five ears (12%) at the click of 50 per s. Conclusion: Abnormal BAER result was seen in 24% of patients with TBM before treatment. Depending on these findings, it can be inferred that hearing impairments must be lower than those values which was detected by BAER during the acute phase of TBM, since the abnormal BAER may be reversible following the illness, returning to normal with recovery.

    Giant ethmoid osteoma with orbital extension presenting with epiphora
    (Int Rhinologic Soc, 2003) Osma, U; Yaldiz, M; Tekin, M; Topcu, I
    Paranasal sinus osteoma is a slow-growing, benign, encapsulated bony tumour that may be commonly asymptomatic, being detected incidentally in 1% of plain sinus radiographs or in 3% sinus computerized tomographic scans. In a patient presenting with epiphora and nasal obstruction, computed tomography disclosed a giant osteoma of the ethmoid. In this article, one patient having giant ethmoidal osteoma with orbital extension is described, and epidemiology, diagnosis, treatment, and pathological findings in paranasal sinus osteoma are reviewed.

    Preauricular hydatid cyst: an unusual location for echinoccosis
    (Springer, 2004) Tekin, M; Osma, U; Yaldiz, M; Topcu, I
    Hydatid disease is an important medical problem in countries of the temperate zones. A 21-year-old female patient was admitted to our outpatient clinics with a complaint of a progressive swelling in the left preauricular region. The case of the patient with hydatid disease that developed in the left preauricular region is presented in detail. Hydatid cyst in this location is rare.
