Publication Metadata only Analgesic effect of magnesium in post-tonsillectomy patients: a prospective randomised clinical trial(2015-09-01) TUGRUL, SELHATTİN; EREN, S. B.; Dogan, REMZİ; VEYSELLER, B.; OZTURAN, ORHAN; TUĞRUL, SELAHATTİN; DEĞİRMENCİ, NAZAN; EREN, SABRİ BAKİ; DOĞAN, REMZI; ÖZTURAN, ORHANThe aim of this study was to assess the analgesic, bleeding and nausea/vomiting effects of magnesium with and without metamizol on post-tonsillectomy patients. This prospective and randomised clinical trial included 54 patients aged 18-63 years who were scheduled for elective tonsillectomy. The patients were randomly divided into two groups and administered either magnesium with metamizol or only metamizol. They had been classified as physical status class I and II using the American Society of Anesthesiologists guidelines. All patients underwent the same surgical procedure performed by a single surgeon. The groups did not differ according to age, sex, or duration of anaesthesia or surgery. Postoperative pain, bleeding and nausea/vomiting were evaluated using the VAS and bleeding and nausea/vomiting scores on the first, fifth and tenth days. On the first, fifth and tenth postoperative days, the VAS scores of the magnesium with metamizol group were significantly lower than those of the metamizol-only group (p1 = 0.001; p5 = 0.015; p10 = 0.015). There were no significant differences in postoperative bleeding and nausea/vomiting scores between the two groups (p = 0.425 and p = 0.258, respectively). This study showed that magnesium enhanced the analgesic effect on post-tonsillectomy pain. Use of magnesium with an analgesic drug may be beneficial for management of post-tonsillectomy pain .Publication Open Access Connecticut (CCCRC) Olfactory Test: Normative Values in 426 Healthy Volunteers(2014-01-01) VEYSELLER, Bayram; OZUCER, Berke; KARAALTIN, Aysegul Batioglu; YILDIRIM, Yalcin; DEGIRMENCI, NAZAN; AKSOY, Fadlullah; ÖZTURAN, ORHAN; DEĞİRMENCİ, NAZAN; AKSOY, FADLULLAH; ÖZTURAN, ORHANApplication of Connecticut Chemosensory Clinical Research Center (CCCRC) olfactory test to healthy Turkish volunteers, obtain normative data set and analyse the role of age, sex and smoking on olfactory scores. The present study was conducted at Bezmialem Vakif University, Department of Otorhinolaryngology. Total of 426 healthy volunteers were subjected to CCCRC olfactory test which consists of n-butanol smell threshold test and smell identification test. Olfactory function score was assessed (0: worst score; 7: best score) and mean scores were calculated. Mean age was (36.7 ± 11.1; range, 17–68). 46.2 % of the subjects were male and 53.8 % were female; 37.1 % were smokers and 62.9 % were nonsmokers. Mean n-butanol threshold score was 6.36 out of 7, mean identification score was 6.34 and mean total score was 6.35. According to CCCRC score: there were no anosmic individuals, 0.5 % were severely hyposmic, 2.6 % were moderately hyposmic,15.3 % were mildly hyposmic and 81.6 % were normosmic. CCCRC olfactory test is cost-effective, simple and practical. It can be easily applied in clinical settings. The CCCRC olfactory test is appropriate for assessment of olfactory function: Turkish population is familiar in terms of the odors used in CCCRC test. The power of this study is that it provides a normative data set against which many factors can be compared.Publication Metadata only -Conchae bullosis-: a rare case with bilateral triple turbinate pneumatisations(2013-01-01) YENIGUN, A.; Ozturan, ORHAN; DEGIRMENCI, NAZAN; YILMAZ, F.; ÖZTURAN, ORHAN; YENİGÜN, ALPER; DEĞİRMENCİ, NAZANBackground: Concha bullosa is the pneumatisation of intranasal conchae (usually the middle turbinate, and rarely the inferior or superior turbinate); however, the term is generally used to describe aeration of the middle concha. Superior concha bullosa is a rare finding, and only a few cases of inferior concha bullosa have been reported in the medical literature. When symptomatic, concha bullosa may cause various problems including nasal congestion, headache, postnasal drip, anosmia and, sometimes, epiphora.Publication Metadata only Investigation of smell and taste function in patients with obstructive sleep apnoea syndrome.(2019-05-01) GOKTAS, SS; Ozturan, ORHAN; YENIGUN, A; DEGIRMENCI, NAZAN; DOGAN, REMZİ; YENİGÜN, ALPER; DEĞİRMENCİ, NAZAN; DOĞAN, REMZI; ÖZTURAN, ORHANPublication Metadata only RGB measurements as a novel objective diagnostic test for otitis media with effusion(2015-04-01) TUGRUL, Selahattin; DEGIRMENCI, NAZAN; Eren, SABRİ BAKİ; Dogan, REMZİ; HAFIZ, Aysenur Meric; Ozturan, ORHAN; DEĞİRMENCİ, NAZAN; EREN, SABRİ BAKİ; DOĞAN, REMZI; ÖZTURAN, ORHANConclusions: This study revealed a significant correlation between red-green-blue (RGB) values of tympanic membrane (TM) images and the presence of effusion in the middle ear. These results confirm that endoscopic RGB evaluation is a rapid and non-invasive procedure yielding objective results. Objective: To investigate, in cases of otitis media with effusion (OME), the correlation of the TM color changes with the presence and viscosity of the effusion in the middle ear. Methods: Endoscopic images of the TMs of 52 patients (group 1) and 52 healthy controls (group 2) were taken during their otologic examinations. RGB values of particular points were measured on the TM images of both groups. Additionally, in group 1 the viscosity of each effusion taken by paracentesis during surgery was also measured intraoperatively with a viscometer. Patients with viscosity values lower and higher than 450 cP (centipoise) were subdivided into groups 1a and 1b, respectively. Results: Study and control groups were comparable regarding the number of patients and their mean ages (p > 0.05). Statistically significant differences were found in RGB values of the TM between groups 1 and 2, but not between groups 1a and 1b.Publication Metadata only Co-existence of the Onodi cell with the variation of perisphenoidal structures(2013-07-01) Ozturan, ORHAN; Yenigun, ALPER; DEGIRMENCI, NAZAN; AKSOY, Fadlullah; VEYSELLER, Bayram; ÖZTURAN, ORHAN; YENİGÜN, ALPER; DEĞİRMENCİ, NAZAN; AKSOY, FADLULLAHThe presence of the Onodi cell (OC) may be accompanied by morphological variations of the neighboring anatomic structures. Such variations carry significant surgical implications and challenges. Pneumatization of the sphenoid sinus induces anterior clinoid pneumatization (ACP), affects the type of the Vidian nerve (VN) canal or alters the courses of the internal carotid artery (ICA), and the optic nerves (ONs) are strongly depending on it. Onodi cell pneumatization may reach and surround the optic nerve in various extension. Our aim in the study was to investigate the effect of Onodi cell-s potential co-existence on these structures. This study was planned as a retrospective and cross-sectional study. This study performed in a tertiary referral center. Coronal computerized tomography images of 999 patients were examined. Using an 64 slices tomography machine, images taken at 3-mm sections were reconstructed using a bone algorithm and evaluated. OCs were present at 212 of the total 320 sides in 160 patients. Type-2 was found to be the most prevalent type of VN canal configuration (Type-2: VN canal partially protrudes into the sphenoid sinus or into the floor of the sphenoid) among all patients (66.5 %) and among those with OCs (71.2 %). The presence or absence of the OC did not cause a statistically significant alteration of the intrasphenoidal course of the VN. The presence of OCs was found to be significant (p < 0.01) in accompanying pneumatization of the anterior clinoid process (34.4 %, 73/212), protrusion (80.1 %, 170/212) and dehiscence (36.3 %, 77/212) of the optic nerve, and protrusion (59 %, 125/212) and dehiscence (20.8 %, 44/212) of the ICA. In 108/320 sides where OCs were absent, no significant correlations existed. This study shows that in the co-existence of an OC, ACP, protrusion and dehiscence of the optic nerve and ICA are encountered at significantly higher rates, while the course of the VN is not necessarily altered.Publication Metadata only University of Pennsylvania smell identification test: application to Turkish population.(2012-01-01) YÜCEPUR, Cemil; OZUCER, Berke; DEGIRMENCI, NAZAN; YILDIRIM, Yalçin; VEYSELLER, Bayram; Ozturan, ORHAN; DEĞİRMENCİ, NAZAN; ÖZTURAN, ORHANPublication Metadata only Olfactory function and olfactory bulb volume in Wilson-s disease.(2019-01-01) DEGIRMENCI, NAZAN; VEYSELLER, B; HANAGASI, H; BILGIC, B; GURBUZ, D; TOPRAK, ALİ; Ozturan, ORHAN; DEĞİRMENCİ, NAZAN; TOPRAK, ALİ; ÖZTURAN, ORHANPublication Metadata only Chondroma of the Nasal Tip(2013-03-01) Ozturan, ORHAN; Yenigun, ALPER; DEGIRMENCI, NAZAN; ÖZTURAN, ORHAN; DEĞİRMENCİ, NAZAN; YENİGÜN, ALPERChondromas are benign lesions composed of mature hyaline cartilage. A nasal chondroma is an infrequent entity and it arises rarely from the nasal septum. Most of the nasal chondroma cases in the medical literature have originated from the posterior part of the septum. This article presents a rare case of nasal chondroma. A 47-year-old female patient consulted to our clinic complaining of a lump of medium hardness at the tip of her nose. Surgery revealed a nasal chondroma, localized at the domal alar cartilage. The case was presented in detail, and the diagnosis, treatment, and follow-up of nasal chondromas were discussed in light of relevant literature.Publication Metadata only Pneumo-Concha Dilatans: Middle Concha Growing in Anterior and Lateral Directions(2013-07-01) Ozturan, ORHAN; DEGIRMENCI, NAZAN; ÖZTURAN, ORHAN; DEĞİRMENCİ, NAZANAeration of the concha is called concha bullosa regardless of the amount and location of the aeration. Middle concha pneumatization is very frequent, and its incidence rate according to the literature is between 14% and 53.6%. Various types of middle concha such as pneumatized, paradoxical, bifurcate, trifurcate, secondary, and accessory have been defined; however, the most frequently observed variation is the pneumatization of the middle concha. In our case, a male patient presented to our clinic with complaints about difficulty breathing through the nose and decrease in the olfaction. The endoscopic examination showed that his right middle concha had grown enough to extend toward the front of the lower concha, and the left middle and lower meatuses were infested by polyps. The paranasal computed tomographic scan of the patient showed that the left middle concha had maxillary sinus invasion at an amount that was enough to fill 25% of the maxillary sinus. In this case presentation, the middle concha pneumatization presenting with maxillary sinus invasion, which we believe is the first case in the literature, is presented as accompanied by the literature.
