Öğe Ameloblastoma originated from maxillary sinus(Springer, 2013) Dogan, E.; Abidin, Z. A.; Ipci, O.; Akoglu, E.[Abstract Not Available]Öğe Effect of phosphodiesterase-5 inhibitor on hearing(Cambridge Univ Press, 2009) Okuyucu, S.; Guven, O. E.; Akoglu, E.; Ucar, E.; Dagli, S.Objective: Following a report of sudden hearing loss in a patient taking phosphodiesterase type 5 inhibitor, and a Food and Drug Administration announcement concerning this class of drugs, a study was planned to investigate if ototoxicity occurs in patients using phosphodiesterase 5 inhibitor for erectile dysfunction. Methods: Eighteen patients with erectile dysfunction who had been using phosphodiesterase 5 inhibitor were included in the study. Audiometric tests were performed on all patients, between the frequencies 250 and 16 000 Hz, before and 1, 5 and 72 hours after drug ingestion. Results: Four patients showed a unilateral threshold decrease compatible with ototoxicity criteria; this change was reversible. A statistically significant difference in pre- versus post-drug hearing thresholds was observed in the right ear at 10 000 Hz (p = 0.008). There were no statistically significant hearing threshold differences at any other frequencies (p > 0.05). Conclusion: Although temporary ototoxicity was noted in four patients, we could not find any permanent, deleterious effect of phosphodiesterase type 5 inhibitor on hearing thresholds.Öğe Effect of the warm and wet environment of the swimming-pool on the bacterial flora of the external ear canal and development of otitis externa in children who attend to swimming course(Galenos Yayincilik, 2006) Akoglu, E.; Cetin, M.; Onlen, Y.; Duran, N.; Sangun, O.; Savas, L.; Ocak, S.Objective: Especially in the summer season, there is an increased incidence of ear infections in the children who attend to the swimming pools. The most frequent ear infection in this group is otitis externa. This study was planned in order to examine whether the microbiologic flora of the normal external auditory canal (EAC) is changed by the pool environment in the presence or absence of cerumen; and to evaluate the relationship of these changes with the external otitis. Methods: Ear swab samples of EAC from 197 children were taken before and 1 month after the swimming course. These samples were evaluated at the microbiology laboratory after the otoscopic examination of each student. Results: The most frequently isolated microorganisms from the samples which were taken before the course were; Staphylococcus epidermidis (76.7%), Diphteroid spp. (47.3%) and alpha-hemolytic streptococci (29.9%) respectively. After the course period, it was determined that the percentage of isolated microorganisms changed, although the order of the frequency of the first three microorganism remained the same (Staphylococcus epidermidis 75.9%, Diphteroid spp. 56.3% and alpha-hemolytic streptococci 41.1%). Only one case of external otitis due to Pseudomonas aeruginosa was seen in the course period. Conclusions: It was concluded that an alteration in the microbiologic flora of the EAC and the presence or absence of cerumen do not play a role in the development of EAC infections provided that the hygienic conditions are constituted and EAC skin is not traumatized.Öğe Investigation of demodex species frequency in patients with a persistent itchy ear canal treated with a local steroid(Cambridge Univ Press, 2014) Cevik, C.; Kaya, O. Aycan; Akbay, E.; Yula, E.; Yengil, Erhan; Gulmez, M. I.; Akoglu, E.Objective: To investigate the frequency of demodex species in the external acoustic meatus in patients with an itchy ear canal. Methods: Patients were assigned to one of three groups. Group one consisted of 54 patients with an itchy ear canal who were using a local agent, while group two was composed of 51 patients with an itchy ear canal who were not using a local agent. Group three consisted of 50 healthy individuals without an itchy ear canal. Results: Demodex species test results were positive in nine (5.8 per cent) of the cases. Six of these positive cases were in group one, two in group two and one in group three. The frequency of demodex species in the external acoustic meatus was similar between those patients with an itchy ear canal who did not use a local agent and the healthy individuals (p = 0.571), but it was significantly higher in those using a local steroid compared with those not using a local agent (p = 0.046). Conclusion: Although demodex species was not significantly higher in patients with an itchy ear canal compared with the control group, use of a local steroid increased the parasite frequency in the external ear canal of affected patients.Öğe Otoplasty: results with anterior scoring of the helical cartilage and conchal resection(Galenos Yayincilik, 2009) Okuyucu, S.; Mutlu, O.; Akoglu, E.; Daglu, A. S.Objectives: The aim of this study is to evaluate results of anterior surface incision of antihelix, suturation and conchal cartilage resection for prominent ear. Methods: Seven ears of four patients were included into the study who were operated between 2004 and 2006. The formation of antihelix was obtained with incision techniques whereas suturation is used for stabilization. Conchal hypertrophia was corrected with cartilage resection. The evaluation of the results was achieved with preoperative and postoperative photographs. Results: Antihelix development failure was seen in three ears whereas conchal wideness or deep conchal bowl causes additional problem in four ears. Postoperative hematom was the only complication which was observed in two patients. A pleasant cosmesis was obtained in all patients except one patient in whom the correction of the ears were asymmetric. Conclusion: Anterior cartilage incisions to maintain antihelix and conchal cartilage resection to reduce hypertrophy gives pleasant cosmetic results with reduced complication risks.
