Öğe Blood-pool SPECT in addition to bone SPECT in the viability assessment in mandibular reconstruction(Verduci Publisher, 2014) Aydogan, F.; Akbay, E.; Cevik, C.; Kalender, E.INTRODUCTION: The assessment of the postoperative viability of vascularized and non-vascularized grafts used in the reconstruction of mandibular defects due to trauma and surgical reasons is a major problem in maxillofacial surgery. AIM: In the present study, we evaluated the feasibility and image quality of blood-pool SPECT, which is used for the first time in the literature here in the assessment of mandibular reconstruction, in addition to non-invasive bone scintigraphy and bone SPECT. We also evaluated whether it would be useful in clinical prediction. PATIENTS AND METHODS: Micro-vascularized and non-vascularized bone grafts were used in 12 Syrian men with maxillofacial trauma. Between days 5-7 after surgery, three-phase bone scintigraphy, blood-pool SPECT and delayed bone SPECT scans were performed. After month 6, the patients were assessed by control CT scans. RESULTS: Of the non-vascularized grafts, one graft was reported as non-viable at week one. At month 6, graft resorption was demonstrated on the CT images. The remaining non-vascularized grafts and all of the micro-vascularized grafts were considered to be viable according to delayed bone SPECT and blood-pool SPECT images. However, only the anterior and posterior ends could be clearly assessed on delayed SPECT images, while blood-pool SPECT images allowed the clear assessment of the entire graft. CONCLUSIONS: The combined use of blood-pool and delayed SPECT scans could allow for better assessment of graft viability in the early period, and can provide more detailed information to clinicians about prognosis in the follow-up of patients undergoing mandibular graft reconstruction.Öğe Correlation between enviromental factors and carboxyhemoglobine levels in pediatric patients(Lippincott Williams & Wilkins, 2014) Koyuncu, O.; Turhanoglu, S.; Tuzcu, K.; Oksar, M.; Akbay, E.; Turan, A.[Abstract Not Available]Öğe Dermoid cyst: A rare entity of the parotid gland(Springer, 2013) Toprak, S.; Ozgur, T.; Gokce, H.; Cevik, C.; Akbay, E.; Atik, E.[Abstract Not Available]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 Juvenile nasopharyngeal angiofibroma, patulous eustachian tube, pediatric nasal septum deviation, closed technique rhinoplasty, choanal atresia, submandibular masses and chronic sialadenitis: Endoscope assisted surgery excluding sinus surgery(Galenos Yayincilik, 2012) Akbay, E.Objectives: The aim of this study is to discuss advantages of endoscopy use in ENT diseases other than sinus surgery. Methods: Thirteen patients [8 men (62%) and 5 women (38%)] who underwent endoscopic surgery between 2011 and 2012 were included to the study. Patients who underwent endoscopic sinus surgery were excluded. All patients were operated by using endoscopy under general anesthesia. External skin incision wasn't performed in any patient. Endoscopic video recordings were captured during surgery. Rigid telescopes with angles of 0, 30, 70 and 90 degrees were used in different angles and operations depending on the necessities. Results: Mean age was 21.77 +/- 15.51 (min. 7-max. 60) years and mean duration of complaints was 32.92 +/- 62.87 (min. 1-max. 240) months. Total excision was performed in 2 patients due to juvenile nasopharyngeal angiofibroma (JNA) via combined transoral and transnasal approach; graft placement was performed in one patient due to a displaced nasal fracture via closed rhinoplasty technique; pediatric septoplasty was performed in 4 patients; choanal atresia was opened via endonasal approach in one patient; hyaluronic acid injection to tuba auditiva was performed in one patient due to a patulous Eustachian tube; mass excision was performed in one patient due to a giant pleomorphic adenoma at soft palate; gland excision was performed in 2 patients due to chronic sialadenitis via transoral approach; and mass excision was performed in one patient via transoral submandibular retroglandular approach. In one patient who underwent JNA excision, a bone defect was observed at the skull base and it was endoscopically repaired by bone graft in the same session. Pathology result was reported as lymphoma in submandibular mass, while it was compatible to chronic sialadenitis in submandibular glands. Patient satisfaction was high in all these approaches without skin incision, while length of hospital stay was minimum. Conclusion: Endoscopy assisted surgery is being increasingly used in ENT field because these techniques are minimal invasive; require shorter hospitalization; and have low morbidity. ByÖğe Myiasis based on squamous cell carcinoma of the external auditory canal(Galenos Yayincilik, 2011) Cevik, C.; Akbay, E.; Arli, C.; Gulmez, M. I.Myiasis is an infestation that occurs by flies larvae. Usually it appears in the dead animals residues and garbage but rarely seen at intact skin or necrotic areas. myiasis cases appears uncommon in our country. In this study we aimed to Show patient with myiasis based on squamous cell carcinoma of the auricula who did not considered surgery interference and any therapy.Öğe Myoepithelioma of tongue(Springer, 2012) Gokce, H.; Ipci, O.; Atik, E.; Ozgur, T.; Akbay, E.[Abstract Not Available]Öğe Topical steroid induced chronic eczematous external otitis with consisting of external ear cavity: A case report(Galenos Yayincilik, 2012) Arli, C.; Cevik, C.; Akbay, E.; Acikalin, A.Chronic eczematous external otitis is often seen in older women, and constant itching outer ear. The inlet part of the external auditory canal red, scaly, dry, and often there is no serumen the remaining parts of the canal. Eighty-year-old male patient with chronic eczematous external otitis due to topical clobetasol propionate were using for nearly 20 years. In the patient's examination, the left auricle is slightly faded and from the external ear canal cartilage instead of bone union was observed ranging from a cavity. Tympanic membrane was normal but pointed out that a slight atrophy of the bone parts of the external ear canal. In this article we will discuss with patients the side effects of long term use of topical steroids.
