Item Endoscopic Modified Medial Maxillectomy for Treatment of Inverted Papilloma Originating From the Maxillary Sinus(2015) Erbek, Selim S.; Koycu, Alper; Buyuklu, Fuat; 0000-0003-1528-0036; 0000-0003-1290-3509; 0000-0003-4825-3499; 25915667; W-5941-2018; AAF-3650-2021; B-7604-2019Endoscopic approaches have become an alternative to external approaches in the treatment of sinonasal inverted papillomas (IPs) in recent years. The aim of this study was to analyze the outcomes of endoscopic modified medial maxillectomy preserving the nasolacrimal duct and the inferior turbinate in selected IP cases. Medical charts of patients diagnosed with IP originating from the maxillary sinus between July 2008 and August 2013 were reviewed. Eight patients who had undergone endoscopic modified medial maxillectomy were included in the study. Attachment of IP was located on the medial wall of the maxillary sinus in all cases. The nasolacrimal duct was preserved in all of the patients. The inferior turbinate was completely preserved in 5 patients, and the anterior part of the inferior turbinate was preserved in 3 patients. The mean follow-up period of the patients was 30.8 months (12-60 mo). None of the patients had recurrence or major complications. The postoperative complaints were minor hemorrhagic discharge and crusting for the first few weeks. Endoscopic modified medial maxillectomy preserving the nasolacrimal duct and the inferior turbinate provides good surgical and functional outcomes in selected IP cases.Item FCN2 c.772G > T Polymorphism Is Associated With Chronic Adenoiditis And/Or Tonsillitis, But Not-4 A > G and-602 G > A(2016) Erkan, Alper N.; Oz, Isilay; Terzi, Yunus K.; Aydin, Erdinc; Ozkale, Murat; Babakurban, Seda Turkoglu; Koycu, Alper; Sahin, Feride Iffet; 0000-0003-0625-1057; 0000-0001-5612-9696; 0000-0001-7138-1400; 0000-0003-1290-3509; 0000-0002-7380-4566; 0000-0001-5067-4044; 0000-0001-7308-9673; 0000-0001-6864-7378; 27368434; A-7806-2016; B-4372-2018; H-1063-2019; AAF-3650-2021; AAJ-1452-2021; AAI-8856-2021; AAC-7232-2020; AAJ-2379-2021Objective: Ficolins are complement activating peptides that play a role in the initial host defense against infectious pathogens. In the present study, we investigated the relationship between single nucleotide polymorphisms (SNPs) in the ficolin 2 gene (FCN2) and chronic adenotonsillitis in pediatric cases. Study Design: Case-control study. Methods: A total of 101 pediatric patients diagnosed with chronic adenotonsillitis and 100 healthy children were enrolled in the study. Genotypes of FCN2 promoter SNPs -602 G>A and -4 A>G, and the exonic SNP c.772G>T were determined by light SNP assay after realtime PCR analysis using genomic DNA samples obtained from peripheral blood samples of all participants. Results: Of the 101 chronic tonsillitis patients, 38 were girls and 63 were boys; the mean age was 5.2 +/- 2.3 years. The c.772G>T SNP frequency was significantly higher in chronic adenotonsillitis cases compared to the control group (p = 0.00); however, no significant difference was determined at positions -602 G>A or -4 A>G (p > 0.05). Conclusions: The FCN2 c.772G>T genotype appears to be associated with predisposition to chronic adenotonsillitis in the pediatric age group. This nucleotide change is likely to influence the level of gene expression and contribute to the development of disease. (C) 2016 Elsevier Ireland Ltd.

The present study evaluates the effect of cigarette smoking on complication and revision rates and compares the functional results of smoking and non-smoking patients. Method The data of 598 patients were retrospectively analyzed, and the age, gender, cigarette smoking status, type of operation, NOSE scores, complications and revision rates were recorded. For the purpose of the study, three different patient groups were defined, being those who had never smoked, those who smoked in the past but had quit and active cigarette smokers. The preoperative and postoperative 6th month Nasal Obstruction Symptom Evaluation (NOSE) Questionnaire scores were compared, and the three groups were compared in terms of complications and the need for revision. Results No differences were identified in the complication rates or revision requirements of the three groups with different cigarette smoking statuses (p=0.17 and p=0.74, respectively). The NOSE scores of the surgery groups and cigarette smoking categories improved significantly after the operation (p=0.01). No difference was identified in the NOSE scores of the groups with different cigarette smoking statuses (p>0.05). Conclusion Active cigarette smoking has no effect on the functional results and rates of complication/revision after septoplasty or septorhinoplasty operation. That said, surgeons should suggest that patients quit smoking preoperatively in order to minimize the general systematic effects of cigarette smoking.Item Effects of Combined Visible and Infrared Light Rhinophototherapy in Patients With Allergic Rhinitis(2023) Koycu, Alper; Bas, Ceren; Musabak, Ugur H.; Erbek, Selim Sermed; Koca, Huseyin Samet; Babakurban, Seda Turkoglu; Bahcecitapar, Melike; https://orcid.org/0000-0003-1290-3509; 36266929; AAF-3650-2021Background Intranasal phototherapy offers an alternative treatment method for patients with allergic rhinitis who cannot benefit from intranasal corticosteroids and oral antihistamines. Different wavelengths have been tried with promising results. Objective In this present study, we aimed to investigate the effects of visible light-infrared light phototherapy on clinical improvements together with its cytologic effects in patients with allergic rhinitis. Methods Patients with confirmed allergic rhinitis were given a 4-week course of intranasal phototherapy treatment. Weekly symptom questionnaires were applied to monitor clinical effects. Nasal lavage specimens were obtained before the start and at the completion of the 4-week therapy. Fluorescence-activated cell sorting analyses of CD16(+), CD24(+), and CD 45(+) cells were performed. Statistical analyses are performed of weekly changes in symptoms and cell counts. Results CD45(+)CD16(high)CD24(+) neutrophil count in nasal lavages decreased significantly whereas CD45(+)CD16(dim/-)CD24(+) eosinophil counts significantly increased and CD45(+) granulocyte counts remained unchanged. Symptom scores including nasal itching, nasal discharge, nasal obstruction, sneezing, eye itching, throat itching, and ear itching all statistically decreased compared to baseline at the end of 4 weeks. Conclusion Four-week course of intranasal phototherapy with visible and infrared light leads to clinical improvement in allergic rhinitis patients.Item Immunological Mechanisms of Allergic Rhinitis(2021) Koycu, Alper; Yucel, Aysegul Atak; 0000-0003-1290-3509; AAF-3650-2021Allergic rhinitis is a specific immunoglobulin (Ig)E-mediated reaction developed against respiratory allergens. The main symptoms of allergic rhinitis; sneezing, runny nose, nasal congestion, itching in the nose, eyes and palate. Cells, cytokines, surface markers, transcription factors and other mediators have been revealed with the sequential removal of nasal biopsy and lavages in human and animal models exposed to allergens over the years. Respiratory allergen induces Th2 lymphocyte proliferation with a combination of cytokines including interleukin (IL)-3, IL-4, IL-5, IL-9, IL-10, and IL-13. These molecules promote allergen specific IgE, mast cells, basophils, eosinophils, adhesion molecules and chemokines. In this review, immunological mechanisms in allergic rhinitis re-examined by reviewing the current literature.Item Evaluation of Oropharyngeal Dysphagia in Elderly Patients with Pharyngeal Aberrant Internal Carotid Artery Using the Eating Assessment Tool-10 (EAT-10)(2021) Jafarov, Sabuhi; Isazade, Artoghrul; Koycu, Alper; Beyazpinar, Gulfem; Bahcecitapar, Melike; Tuzuner, Arzu; 0000-0001-9735-3504; 0000-0002-8467-0225; 0000-0003-1290-3509; 0000-0001-9735-3504; 34226957; AAI-8044-2021; AAJ-1829-2021; AAF-3650-2021; AAJ-2487-2021Pharyngeal aberrant internal carotid artery (PAICA) has been reported to be a cause of oropharyngeal dysphagia (OD) in case reports. However, as there have been no clinical studies, the relationship between PAICA and OD is not clear. The aim of this study was to investigate the perception of OD in elderly PAICA patients using the Eating Assessment Tool-10 (EAT-10). A study group (Group 1) was formed of patients diagnosed with PAICA from the visualization of a pulsatile mass in the pharynx in flexible fiberoptic endoscopic examination and carotid magnetic resonance angiography tests, and a control group (Group 2) was formed of age-matched healthy volunteers. The study group was subdivided as patients with unilateral PAICA (Group 1a) and patients with bilateral PAICA (Group 1b). The Turkish version of the EAT-10 was applied to all the participants. Total EAT-10 points of >= 3 were accepted as abnormal. Normal (< 3) and abnormal (>= 3) total EAT-10 points were determined in 88.9% (24/27) and 11.1% (3/27), respectively, of the control group, in 55.2% (16/29) and 44.8% (13/29) of Group 1, in 70.6% (12/17) and 29.4% (5/17) of Group 1a, and in 33.3% (4/12) and 66.7% (8/12) of Group 1b. A statistically significant difference was determined between the control group and Group 1 and Group 1b in respect of abnormal (>= 3) EAT-10 total points (p = 0.007, p = 0.001, respectively). No statistically significant difference was determined between the control group and Group 1a (p = 0.227). Problems (EAT point >= 1) in item 4 (swallowing solids takes extra effort) were experienced by 13 (44.8%) patients in Group 1, 9 (75%) patients in Group 1b, and 5 (18.5%) subjects in the control group (p < 0.05). These results demonstrated that unilateral PAICA does not significantly affect swallowing, whereas bilateral PAICA created a significant negative effect. These patients experience more problems when swallowing solid food.Item Effect of Suture Type and Suture Distance on Holding Strength in Nasal Septal Laceration Model(2021) Koycu, Alper; Hizal, Evren; Erol, Ozan; Buyuklu, Adnan Fuat; 0000-0003-1290-3509; 0000-0002-9699-6783; 0000-0002-4209-9403; 33912854; AAF-3650-2021; A-5853-2018Objective: Septal mucosal-perichondrial flaps can be lacerated during the elevation of the flaps. Appropriate repair of the lacerations is essential to prevent the development of septal perforation during the healing process. We aimed to determine the superior suture type and suture distance to use in repairing the lacerations of nasal septal mucosal-perichondrial flaps. Methods: The study used 128 nasal septal mucosal-perichondrial flaps prepared from sheep heads. Experimentally induced lacerations on the mucosal-perichondrial flaps were sutured with two interrupted sutures using one of four suture materials (4-0/5-0 Polyglactin 910, 4-0/5-0 Polydioxanone) and leaving either 5 mm or 10 mm distance between the sutures. Maximum tissue holding strength (HSmax) was measured for each suture material and suture distance used. Results: Mean HSmax values were higher for Polyglactin 910 sutures (p<0.001) and 10 mm suture distance (p=0.008) when the groups were compared in terms of suture material and suture distance, respectively. There was no statistically significant difference between the mean HSmax values of sutures with 4-0 and 5-0 diameters (p=0.057). Conclusion: Polyglactin 910 suture material with 10 mm space between two adjacent sutures may be more durable than the other suture materials when repairing nasal septal mucosal lacerations.Item Age- and Gender-Related Variability in Nasal Tip Support(2020) Koycu, Alper; Erol, Ozan; Buyuklu, Fuat Adnan; Jafarov, Sabuhi; Berker, Sinem; 0000-0003-1528-0036; 0000-0003-1290-3509; 0000-0002-7302-4199; 31834522; W-5941-2018; AAF-3650-2021; AAI-8044-2021Background The age at which nasal tip support changes start to occur is unknown. Evaluation of nasal tip support is difficult, especially as the ideal nasal tip support pressure remains elusive. The aim of this study is to determine the nasal tip support pressure alterations relative to age and sex. Objectives The aim of this study is to determine the changers in resistance of the nasal tip support in relation to age and sex. Methods This prospective clinical study was conducted between January and April 2019 at a tertiary health facility. Nasal tip resistances were measured in four different age-groups (20-29, 30-39, 40-64, and > 65 years) with a digital Newton meter. A total of 159 patients with a minimum of 36 patients per group were included in the study. Nasal tip resistance measurements were compared among nasal tip displacement distances of 2, 3, and 4 mm, focusing on age and sex. Results The nasal tip resistance of the 20-29 age-group was significantly higher at 2, 3, and 4 mm nasal tip displacement distances, when compared with the 30-39 and 40-64 age-groups, whereas compared to the > 65 years group, it was significantly higher at 3 and 4 mm nasal tip displacement distances (p < 0.005). Nasal tip resistance of males was found to be significantly higher than that of females, at 3 and 4 mm nasal tip displacement distances (p < 0.001). Conclusions Nasal tip resistance is higher in males and universally decreases significantly after 30 years of age while remaining constant at later ages. Therefore, surgeons should prefer nasal tip resistance increasing techniques in the rhinoplasty operations that are performed on patients even from early years of age, in order to maintain and strengthen the nasal tip resistance.Item Device-related epistaxis risk: continuous-flow left ventricular assist device-supported patients(2020) Koycu, Alper; Vural, Omer; Bahcecitapar, Melike; Jafarov, Sabuhi; Beyazpinar, Gulfem; Beyazpinar, Deniz Sarp; 0000-0003-1290-3509; 0000-0001-7157-0850; 0000-0003-4324-9458; 0000-0002-7302-4199; 32556786; AAF-3650-2021; AAJ-1454-2021; AAI-9939-2021; AAI-8044-2021Background The aim of this study was to analyze the effect of device-dependent factors on epistaxis episodes comparing patients supported with a continuous-flow left ventricular assist device (CF-LVAD) to patients under the same antithrombotic therapy. Methods Patients who underwent CF-LVAD between 2012 and 2018 were reviewed retrospectively from the institutionally adopted electronic database. Patients who underwent mitral valve replacement (MVR) surgery receiving the same anticoagulant and antiaggregant therapy were included as a control group. Demographics, epistaxis episodes, and nonepistaxis bleeding between the two groups were compared. Results A total of 179 patients met the inclusion criteria (61 patients CF-LVAD group, 118 patients MVR group). The median (range) follow-up periods for the study (CF-LVAD) and control (MVR) groups were 370 (2819) and 545.70 (2356) days, respectively. There was a significant difference for frequency of bleeding episodes per month between CF-LVAD and MVR groups (p = 0.003 < 0.05). The most common site of bleeding was the anterior septum in both groups (90.9% for the CF-MVR group and 100% for the MVR group). While 14 patients (23%) had nonepistaxis bleeding in the CF-LVAD group, only two patients (1.7%) had nonepistaxis bleeding in the MVR group. There were significant differences in nonepistaxis bleeding rates between the CF-LVAD and MVR groups (chi(2)=19.79,p < 0.001). Conclusion Both epistaxis and nonepistaxis bleeding rates were higher in the CF-LVAD group than in the MVR group. This suggests that the use of CF-LVAD support could directly increase the risk of hemorrhagic complications.
