Despite being a benign tumor, it can be aggressively destructive in surrounding tissues and bones by acting locally. (e gold standard treatment method is the surgical excision of the tumor. (is case report is a case of angio-broma, a 32-year-old asymptomatic male patient with no evidence of clinical signs and endoscopic examination, which is recognized as a localized vascular mass lesion in the right sphenoid sinus on the cranial MR imaging. We prepared this case report that may represent an angio-broma localized only within the sphenoid sinus which is very rare in the literature.Publication Open Access Association of accessory sphenoid septa with variations in neighbouring structures(2017-01-01) AKSOY, FEYZA MÜBERRA; ÖZTURAN, ORHAN; GOKTAS, S.S.; YENİGÜN, ALPER; YENİGÜN, ALPER; AKSOY, FADLULLAH; ÖZTURAN, ORHANPublication Metadata only Key stone plasty and asymmetric hump resection in crooked nose deformity(2022-09-01) Balikci H.; YENİGÜN A.; ÇELİK İ.; AKSOY F.; DOĞAN R.; ÖZTURAN O.; YENİGÜN, ALPER; ÇELİK, İSMAİL; AKSOY, FADLULLAH; DOĞAN, REMZI; ÖZTURAN, ORHAN© 2022 Elsevier Inc.Objective: The aim of this study is to propose a new approach in crooked nose deformity with key-stone plasty and asymmetric hump resection. Method: Twelve patients with crooked nose deformities were operated using the open rhinoplasty technique. Our method, unlike other methods, has two different steps. Following asymmetric hump resection, cartilaginous and osseous septum were cut separated at the key stone area or more caudally and fix the septum with sutures again by allowing them to slide over each other in a way that directs the septum to the midline. If there is an inability to reveal the septum, we apply a longer spreader graft to the cartilage septum side. Results: The mean ages were 27.4 years. The mean follow-up time of the patients was 19.1 months. No complications were observed due to this technique. This technique was effective in the treatment of all our patients with crooked nose deformities. Conclusion: A novel surgical approach with key-stone plasty and asymmetric hump resection method was proposed in crooked nose deformity with a video animation.Publication Open Access Dry Eye and Dry Nose Caused by the Effect of Allergic Rhinitis on Tear and Nasal Secretion Osmolarity.(2020-03-17T00:00:00Z) Elbay, A; Yenigun, A; Ozturan, O; Bayraktar, H; Ozer, Ömer Faruk; Dogan, R; YENİGÜN, ALPER; ELBAY, AHMET; ÖZDEM, ABDULLAH; ÖZER, ÖMER FARUK; DOĞAN, REMZI; ÖZTURAN, ORHANObjective: Allergic rhinitis is a type 1 hypersensitivity reaction of immunoglobulin E in the rhino-ocular mucosa. This study was planned to demonstrate in patients with allergic rhinitis to evaluate changes in tear, nasal secretions, and blood osmolarity compared to healthy individuals. Method: Forty allergic rhinitis patients, 25 patients with acute upper respiratory tract infections, and 26 healthy participants were included in the study. Positive patients with allergic symptoms and skin prick test results were included in the allergic rhinitis group. Tear, nasal secretion, and blood osmolarity values were examined for the 3 groups. Result: In patients with allergic rhinitis, tear and nasal secretion osmolarity values were significantly higher in patients with acute upper respiratory tract infections and those of the healthy participants (P ¼ .001, P ¼ .038). In blood osmolarity measurements, there was no statistical difference between the groups (P ¼ .489). In patients with allergic rhinitis, Schirmer test results were significantly shorter than patients who had acute upper respiratory tract infection and those of the healthy participants (P ¼ .001, P ¼ .001). Patients with allergic rhinitis and acute upper respiratory tract infections had significantly shorter Schirmer test results than in healthy participants (P ¼ .001, P ¼ .001). Conclusion: Tear osmolarity was increased in allergic rhinitis patients, and this was thought to lead to dry eye findings. In the presence of allergic rhinitis, nasal secretions were found more hyperosmolar than tears. Nasal secretion osmolarity was higher in allergic rhinitis patients than in patients with acute upper respiratory tract infections and control group.Publication Metadata only Diklofenak Sodyum, İbuprofen ve Parasetamol İçeren Nazal Analjezik Spreylerin Formülasyonu ve İn Vitro Toksisitesinin Değerlendirilmesi(2022-11-16) Yenigün A.; Sütcü A.

Methods: Thirty patients with nasal polyps and a group of 20 healthy patients (control group) were included in this study. Mucosa was obtained from the polyps of patients with nasal polyposis and from the middle turbinate of the control group patients by means of biopsy. The samples were stored at -80 °C until molecular analysis by polymerase chain reaction was carried out. Results: In the control group, the human coronavirus and human rhinovirus were diagnosed in one of the patients and the human respiratory syncytial virus in another. In the group with nasal polyposis, the influenza B virus was identified in one of the patients and the human coronavirus in another. Conclusion: The results did not demonstrate a statistically significant relationship between nasal polyposis and respiratory viruses.Publication Open Access Factors influencing the longevity and replacement frequency of Provox voice prostheses.(2015-11-01) OZKUL, MH; Meric, AYŞENUR; TUGRUL, SELHATTİN; EREN, SABRİ BAKİ; YENIGUN, A; YENİGÜN, ALPER; EREN, SABRİ BAKİ; TUĞRUL, SELAHATTİN; MERİÇ HAFIZ, AYŞENURINTRODUCTION This study aimed to assess the factors that influence the longevity and replacement frequency of Provox voice prostheses following their placement. METHODS The medical records of 27 patients who received Provox voice prostheses after total laryngectomy and attended follow-up regularly between 1998 and 2012 were retrospectively reviewed. The success rate of the Provox voice prostheses (i.e. whether speech was achieved), quality of speech achieved, number and type of complications encountered, frequency of prostheses replacement and reasons for prostheses replacements were evaluated. RESULTS All 27 patients were men and their mean age was 63.0 (range 43–78) years. The mean follow-up period was 60.3 (range 1–168) months. Fluent and understandable speech was achieved in 85.0% of the patients. The mean duration before prosthesis replacement had to be performed was 17.1 (range 1–36) months. The most frequent complication was fluid leakage through the prosthesis. There was a strong positive correlation of 77.1% between the longevity of prostheses and postoperative follow-up duration (r = 0.771; p < 0.01). CONCLUSION The voice prosthesis is a tool that can be delivered in a practical fashion and replaced easily with no serious complications. It is a means by which speech can be restored, with a high success rate, after total laryngectomy. In the present study, we found that postoperative follow-up duration was the most important factor influencing the longevity of the Provox voice prosthesis.Publication Metadata only Assessment of patients with nasal polyposis by the neutrophil-to-lymphocyte ratio and eosinophil-to-lymphocyte ratio.(2015-01-01T00:00:00Z) Yenigün, Alper; YENİGÜN, ALPER
