A retrospective analysis of the relationship between rhinosinusitis and sinus lift dental implantation
No full textIntroduction Dental implants have been associated with the occurrence of postoperative rhinosinusitis. In some patients, preoperative sinus lifting must be performed to increase the chances of successful implant placement. This retrospective study examines the relationship of dental implants after sinus lifting with the occurrence of postoperative rhinosinusitis. Methods A total of 268 dental implants were inserted in 94 patients (62 Males, 32 Females) between 2011–2013. The ages ranged from 29–71 (in males) and 33–64 (in females). Additionally, bilateral sinus lifing was performed in 51 patients, and unilateral sinus lifting was performed in 43 of the patients. Patients were evaluated for sinus pathology for a period of 5–47 months postoperatively using a satisfaction questionnaire, conventional radiographic examination, and nasal endoscopic examination. Results Four of the patients (4.2%) had a complication of postoperative sinusitis and were treated medically. In one patient, the implant was unsuccessful (even after treatment) and was removed. None of the patients needed surgery due to the sinusitis or any associated complications. Conclusion The risk for postoperative rhinosinusitis was found to be higher in patients who suffer from chronic sinusitis and in cases in which a large amount of graft was utilized for sinus lifting. These predisposing factors need to be considered when evaluating patients for dental implants and sinus lift procedures.

Olfaktör yarık kaynaklı bilateral nasal polip
No full textNasal polyps generally have similar symptom, they generally originate from ethmoid infundibulum, mucosal contact areas of the uncinate process and middle turbinate. However nasal polyps rarely arise from different and unexpected locations in the nasal cavity such as septum, cribriform plate and olfactory cleft. In this article, we report 63 years old men, had a history of nasal obstruction and loss of smell for six years, diagnosed with bilaterally olfactory cleft originated nasal polyps, which is a very rare site of origin

Varol, Fusun (Trakya Author)Macro Domain Containing 2 (MACRO D2) gene is a gene from macro family which is highly expressed in the ventriculer zone of the brain during embryonic development. Association between Autism spectrum disorders and MACRO D2 gene polymorphisms has been reported before [1] . Deletion in MACRO D2 gene has also been associated with Kabuki Syndrome which is a well described congential anomaly syndrome [2]
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
A Rare Pathology of Postauricular Region: Apocrine Hidrocystoma
No full textApocrine histocyctoma in the postauricular region is a very rare antity. Apocrine hidrocystomas which arise from the proliferation of apocrine glands are commonly a solitary mass diameter of 3-15 mm and located in periorbital region and axilla. It is very rare for apocrine hidrocyctoma to locate in postauricular region. The management of these lesions are extensive surgical excision. A 47 years old woman attended to our outpatient clinic with a painless mass in retroauricular region whose physical examination revelaed a mass consisting of conglomerating, flesh colored, multiple vesicules aproximately 10x15 mm in diameter. In this paper, we present a case whose histopathological examination diagnosed apocrine hidrocyctoma after extensive surgical examinatio
Strength-based design of a sunflower stalk cutter machine design using finite element analysis and experimental validation
No full textIn this study, the total algorithm of the strength-based design of the system for mass production has been developed. The proposed algorithm, which includes numerical, analytical, and experimental studies, was implemented through a case study on the strength-based structural design and fatigue analysis of a tractor-mounted sunflower stalk cutting machine (SSCM). The proposed algorithm consists of a systematic engineering approach, material selection and testing, design of the mass criteria suitability, structural stress analysis, computer-aided engineering (CAE), prototype production, experimental validation studies, fatigue calculation based on an FE model and experimental studies (CAE-based fatigue analysis), and an optimization process aimed at minimum weight. Approximately 85% of the system was designed using standard commercially available cross-section beams and elements using the proposed algorithm. The prototype was produced, and an HBM data acquisition system was used to collect the strain gage output. The prototype produced was successful in terms of functionality. Two- and three-dimensional mixed models were used in the structural analysis solution. The structural stress analysis and experimental results with a strain gage were 94.48% compatible in this study. It was determined using nCode DesignLife software that fatigue damage did not occur in the system using the finite element analysis (FEA) and experimental data. The SSCM design adopted a multi-objective genetic algorithm (MOGA) methodology for optimization with ANSYS. With the optimization solved from 422 iterations, a maximum stress value of 57.65 MPa was determined, and a 97.72 kg material was saved compared to the prototype. This study provides a useful methodology for experimental and advanced CAE techniques, especially for further study on complex stress, strain, and fatigue analysis of new systematic designs desired to have an optimum weight to strength ratio.Trakya University Scientific Research Projects Coordination Unit (TURKEY) [2019/158, 2019/47, 2180668, 1512]; Becan Makine Co.; Irtem Agricultural Machinery Industry.

Auricular Lobuloplasty
No full textObjective:To evaluate surgical outcomes of auricular lobuloplasy.Methods:In total, 13 patients (10 females and 3 males; average age, 32.3±8.48 years; range 21-44 years) who underwent auricular lobuloplasty were included in this study. Demographic characteristics, cause of surgery, presence of complications, and patient satisfaction were evaluated.Results: The mean follow-up was 16.5±9.6 months with the shortest and the longest follow-up being 6 and 34 months, respectively. Surgeries were performed under local anesthesia in 10 cases (76.9%) and under general anesthesia in three cases (23.1%). Lobuloplasty were performed in eight cases (61.5%) with a diagnosis of partial lobule cleft, four cases (30.7%) with a diagnosis of elongated lobule, and one case (7.8%) with a diagnosis of congenital earlobe cleft. There were no postoperative complications and revision surgery was not necessary for any of the patients.Conclusion:Multiple surgical techniques exist for repairing earlobe deformities. Auricular lobuloplasty is a surgical procedure that has several advantages including safety, ease of use, and effectiveness
