Assessment of Approaches of Otorhinolaryngologists in Facial Plastic and Nasal Surgery: A Survey Study
No full textObjective: To assess approaches and experiences of otorhinolaryngologists in facial plastic and nasal surgery. Methods: In total, 234 surgeons (191 males and 43 females; average age, 37.22 +/- 8.4 years; age range, 26-63 years) were included. All participants were given a questionnaire comprising 22 multiple choice and closed-ended questions. All responses to the questionnaires were analyzed. Results: Of 234 participants, 42 (17.9%) were residents and 192 (82.1%) were specialists in otorhinolaryngology. The most challenging cases in rhinoplasty were crooked nose (33.8%), ideal nasal dorsum (18.8%), revision cases (13.2%), and skin deformities (11.1%). The photodocumentation rate by surgeons before and after procedures of facial plastic surgery was 86.3%, whereas the intraoperative photodocumentation rate by surgeons was 47%. The most common facial plastic surgery procedures other than rhinoplasty were otoplasty (68.4%), filler-Botox-fat injections (20.5%), and mentoplasty (18.4%). Conclusion: This survey study is quite important because it assesses approaches of otorhinolaryngologists in facial plastic surgery. Although this study provides more valuable data for determining the current status, further studies with larger number of surgeons are required
Results of the Endoscopic Anterior Skull Base Cerebrospinal Fluid Rhinorrhea Repair Without a Rigid Graft: A Retrospective Analysis
No full textWegener'S Granulomatosis Presenting With An Isolated Paranasal Sinus Involvement In A Child
No full textWegener's granulomatosis which is rarely seen in children is an idiopathic necrotizing granulomatous vasculitis, affecting primarily paranasal sinuses, nasopharynx, lungs, kidneys and joints. In this article, we report a very rare case of eight-year-old boy presenting with Wegener's granulomatosis of paranasal sinuses without lung, kidney and any other organ involvement. We discuss the diagnosis, treatment and the differential diagnosis of paranasal sinus involvement in Wegener's granulomatosis in the light of literature data.WoSScopu
Endonasal Choanal Atresia Repair; Evaluating the Surgical Results of 58 Cases
No full textBackground. Choanal atresia is the most common congenital nasal anomaly, with an incidence of 1:5000-1:8000 live births. Atresia can be seen as membraneous, bony or mixed type. When it is bilateral, it is accepted life-threatening, therefore bilateral atresia necessitates immediate intervention. Diagnosis is confirmed by endoscopic examination and computed tomography. The absolute treatment is surgical, and different approaches have been proposed. Methods. Herein, we describe our 15-year experience in the treatment of 58 patients of congenital choanal atresia with transnasal endoscopic approach, and we compare the efficacy of placement of an intranasal stent and applying mitomycin while endoscopic microsurgical repair. Results. The study included 41 female patients (71%) and 17 male patients (29%) with congenital CA. The mean age was 3 years ranging from 10 days to 16 years. The atretic plate was bilateral in 24 patients (41%) and unilateral in 34 (59%). The most common atresia type was the mixed type with 29 patients (50%). A total of 17 patients (29%) required postoperative revision(s). Postoperative revisions were more frequent among patients with bilateral CA (50%), and with mixed CA (31%). Stenting was used additionally by surgical correction for 10 patients. After stenting, fibrosis and restenosis was seen in 7 patients (79%). Mitomycin C was applied peroperatively in 8 patients. Restenosis after mitomycin application was seen in 4 patients (50%). Conclusions. By our experience, endoscopic microsurgical repair of atresia proved to be an effective and safe procedure, results compared with adjuvant treatment modalities like stent or mitomycin C use, was not better. Restenosis was the major problem seen after surgical correction
Usability Testing Of Digital Libraries: The Experience Of Eprints
No full textDigital libraries should provide a qualified service in allowing their users to access data within a well-organized format. It is critical to enrich interaction among users and the interface. To measure the level of interaction, common analyses such as usability tests or socio-technical analyses are practiced throughout the literature. The interfaces can be enhanced with the data gathered from these types of analyses. The main aim of this study is to realize a qualitative usability test for the users of the Digital Archive of Hacettepe University Department of Information Management. The archive in question was exclusively created by this paper's authors who have participated in the project. In our case, a formal usability test was chosen for the analysis and a total of 5participants -not only from library staff or those who practiced information sciences- but also from different areas have participated in the study. The test was divided into three sections; pre-test, usability test and post-test. A total of 4questions were identified which aimed at measuring the ease of finding an article, accessing full texts, signing up for a new account and finding a given author. The preliminary findings showed that the most convenient option that EPrints software provided was in finding an article, as all of the participants have managed to answer this question fairly easy and quick. On the other hand, the most challenging situation proved to be signing up for a new account. The main reason behind this was discovered to be the sending and receiving of the confirmation e-mails in the activation procedure. There are a few papers in the literature which evaluates EPrints through utilizing usability test. Consequently, the results from this study can be considered important in not only improving the quality of the tested archive, but also the EPrints software itself. (C) 2014 Elsevier Ltd.

The Oblique Split Method A Novel Technique For Carving Costal Cartilage Grafts
No full textImportance: Autogenous rib cartilage is widely used in the septorhinoplasty cases with major structural grafting requirements. However, there is a risk of warping over time. Objective: To introduce a novel method for carving costal cartilage grafts to obtain straight grafts of varying thicknesses and to eliminate the risk of warping. Design: Between 2007 and 2011, a total of 43 consecutive patients underwent septorhinoplasty using autogenous costal cartilage grafts carved by the oblique split method (OSM). Setting: The Ankara Training and Research Referral Hospital, Ankara, Turkey. Participants: The study included 43 patients with saddle nose deformity and revisional rhinoplasty with a depleted source. All patients were followed-up for a period ranging from 12 to 37 months (mean, 19.2 months) after surgery. Interventions: All patients underwent open or closed septorhinoplasty. Autogenous costal cartilage was carved with the OSM to obtain grafts suitable for use as columellar strut, dorsal onlay, L-strut, lateral crural strut, caudal extension, and tip or speader grafts in selected cases. Main Outcome Measures: Patients were evaluated by inspection, palpation, and photographic documentation before surgery. Inspection, palpation, and photographic documentation were carried out every 6 months and 12 months after surgery and once a year thereafter. Results: Patient satisfaction in terms of form and function was achieved in 41 patients (95%). Two patients required reoperation for further tip projection (n=1) and alar batten graft displacement (n=1). No complication was observed as a result of graft warping, resorption, or fracture. Conclusions and Relevance: The OSM provides straight costal cartilage grafts of varying thicknesses without the risk of warping. Because they strictly preserve their straight form, the grafts may safely be modified into rectangular shape or carved asymmetrically and/or have their edges beveled. Current data from this study suggest that the OSM offers a flexible and reliable reconstructive option for the rhinoplasty surgeon.WoSScopu
