    In bullous middle turbinate surgery, controversy exists over which side of the bullous middle turbinate should be removed, as the distribution of human olfactory neuroepithelium is unclear. This study evaluated whether the middle turbinate tissue of patients undergoing endoscopic concha bullosa surgery contains functional olfactory epithelium. This prospective clinical study was conducted in tertiary referable center. It detected 70 conchae bullosa in 48 patients with sinonasal symptoms, who underwent paranasal computed tomography (CT) that showed pneumatization of the middle concha. All samples were obtained under general anesthesia. Three samples were obtained from each bullous middle turbinate: one each from the anterior, medial, and lateral portions. The mucosa from each sample was stained with olfactory marker protein (OMP). In total, 210 middle turbinate samples were taken from 48 patients during endoscopic surgery for conchae bullosa. The patients were 22 females and 26 males. Of the 70 conchae bullosa, OMP-stained nerve tissue was found in the lateral, anterior and medial aspects of 57 (81.4 %), 42 (60.0 %) and 23 (32.8 %) of the bullous middle turbinates, respectively. OMP-stained nerve tissue was found in 122 (58.1 %) of the 210 bullous middle turbinate tissue samples. OMP-stained nerve tissue was found on the lateral surface of the bullous middle turbinate more often than the medial surface. Therefore, during the concha bullosa surgery, OMP-stained nerve tissue found at least in the medial part of concha, suggested that the opening of the medial part of middle concha.

    Tension pneumocephalus: an extremely small defect leading to an extremely serious problem

    Background: Pneumocephalus is a pathology characterized by air influx into the intracranial region. It may occur after head trauma and rarely after endoscopic sinus surgery. As the amount of air increases, this can cause neurological disorders with a mass effect and this condition is called tension pneumocephalus.

    Relationship of olfactory function with olfactory bulbus volume, disease duration and Unified Parkinson-s disease rating scale scores in patients with early stage of idiopathic Parkinson-s disease
    (2013-10-01T00:00:00Z) Hakyemez, Husniye Aylin; Veyseller, Bayram; Ozer, Feriha; Ozben, Serkan; Bayraktar, Gulum Ivgin; Gurbuz, Defne; Cetin, Sibel; YILDIRIM, YAVUZ SELİM; YILDIRIM, YAVUZ SELİM
    We aimed to investigate the relationship between olfactory function and olfactory bulbus (OB) volume, disease duration and Unified Parkinson-s disease rating scale (UPDRS) scores in early stage idiopathic Parkinson-s disease patients. The University of Pennsylvania Smell Identification Test (UPSIT) was used for the evaluation of olfactory function. UPSIT scores for patients with Parkinson-s disease were significantly lower than controls. There was no significant difference between stage 1 and stage 2 patients. OS volumes were higher in stage 1 and 2 patients than controls, but there was no statistical difference between the three groups. No significant correlation was found between UPSIT and UPDRS total scores, nor between UPSIT scores and disease duration in stage 1 and 2 patients. According to our results, we propose UPSIT be used as a screening test to diagnose presymptomatic patients, but not OB volumes. (C) 2013 Elsevier Ltd. All rights reserved.

    Dynamometric Analysis of Normative Auricular Stiffness and Comparison With Operated Prominent Ears
    (2015-10-01) Ozturan, ORHAN; Dogan, REMZİ; OZUCER, Berke; Yildirim, YAVUZ SELİM; MERIC, Aysenur; ÖZTURAN, ORHAN; DOĞAN, REMZI; YILDIRIM, YAVUZ SELİM
    Aim:Stiffness of the auricular cartilage is the main determining factor for the choice of operative technique of the prominent ear deformity. The aim of this study is to evaluate the stiffness of normal appearing ears objectively and quantitatively, compare the results with the operated prominent ear patients, and present prospective short-term dynamometric evaluation of the operated prominent ear patients.Patients and Methods:A total of 190 volunteers without ear deformities were recruited and 9 age groups were formed: group (5-9), group (10-14), group (15-19), group (20-24), group (25-29), group (30-34), group (35-39), group (40-49), and group (50+). Total 28 ears (14 patients) with otoplasty were included in the study as group (operated 5-9) and group (operated 10-14). In addition, 3 patients with prominent ear deformity were prospectively followed for dynamometric changes that occur with otoplasty operation. The auriculocephalic angle (ACA) was measured once and auricle to scalp distance was measured at 4 different standardized levels. Ear stiffness was measured on each ear individually at 4 different points over the antihelix using digital computer-aided dynamometry. Each ear was compared in terms of ACA, distance, and dynamometric values.Findings:Dynamometric values tend to increase with age, which increase and peak around 35 years of age and declines after 40 years of age. Measurements of the first 2 age groups were statistically different compared with the other groups. Postoperative dynamometric measurements (DNM) of group (operated 5-9) were similar with normative values of group (5-9) and postoperative satisfaction visual analogue scale (VAS) score was 92.8%. Postoperative DNM of group (operated 10-14) were higher compared with normative values of group (10-14) for each different measuring level and the postoperative satisfaction VAS score was 75.3. A total of 3 patients with prominent ears had lower dynamometric values preoperatively; these values approached closer to normative values of their age group postoperatively.Conclusions:Results show that auricular cartilage stiffens and malleability decreases with increased age. This stiffness peaks in the 35-39 age group and declines after 40 years of age. Dynamometric values increase, at all levels, suggesting increased cartilage stiffness is related to age. In the scope of these results, cartilage sparing techniques are more suitable for 5 to 14 years of age and cartilage-cutting techniques are more suitable for older patients.
