Öğe Evaluation of the treatment results of laryngeal carcinoma: our experience over 10 years(Tubitak Scientific & Technological Research Council Turkey, 2012) Karatas, Erkan; Baysal, Elif; Durucu, Cengiz; Baglam, Tekin; Bayazit, Yildirim Ahmet; Kanlikama, MuzafferAim: To retrospectively analyze the treatment results for laryngeal carcinoma and to find the impact of the clinical parameters on the survival of the patients. Materials and methods: The medical records of 150 consecutive patients, operated on for laryngeal squamous cell carcinoma between 1991 and 2009, were reviewed. Tumor localization, TNM stages, treatment modalities, radiotherapy, second primary tumors, and tumor recurrence were recorded, and the survival data were obtained. Results: Neck metastasis was rare (3.6%) in T1 and T2 glottic tumors, while there was a significant increase in the rate of N+ neck (35%) in T3 and T4 glottic tumors (P < 0.05). N+ neck was encountered in 28% of the early and 33% of the late-stage supraglottic cancers (P > 0.05). There was a significant relation between survival and tumor recurrence (P < 0.05), whereas the other clinical parameters were not associated with survival (P > 0.05). The risk for death of the disease increased by 63.3% when tumor recurrence occurred (odds ratio = 6.3573). Conclusion: Aggressive treatment of the primary tumor and neck may eliminate the impact of advanced tumor stage on survival. Local and regional recurrence and second primary diagnosis are the most important factors involved in survival in laryngeal carcinoma.Öğe Intra- and postoperative electrically evoked stapedius reflex thresholds in children with cochlear implants(Elsevier Ireland Ltd, 2012) Baysal, Elif; Karatas, Erkan; Deniz, Murat; Baglam, Tekin; Durucu, Cengiz; Karatas, Zeynel Abidin; Mumbuc, SemihObjectives: The aim of this study was to investigate whether there is a significant correlation between intra- and postoperative electrically evoked stapedius reflex thresholds (eSRTs) in children with cochlear implants. Methods: Sixty-five pediatric cochlear implant users were included in this study. All patients had congenital prelingual hearing loss. The round window approach was used in all patients. The eSRTs were intraoperatively measured using the 1st, 3rd, 6th and 12th electrodes of the cochlear implant. The measurements taken during the first fitting of the device were taken again one month after surgery. We used paired-sample t-tests to determine the correlation between intra- and postoperative eSRTs. Results: The eSRT analysis revealed a statistically significant difference between the intra- and postoperative thresholds. A correlation analysis did not reveal any correlation between intra- and postoperative eSRTs. Conclusion: Intraoperative eSRT measurements were unable to predict early postoperative eSRTs.

Methods: Thirty-nine children underwent CI surgery were included for this study. The surgical procedures consisted of RW and Promontory cochleostomy. ESRT for each 1st, 3rd, 6th and 12th electrodes (E) were determined. Statistical evaluation was done for the comparison of the thresholds and duration times for both groups. Results: The duration times of ESRT for E1, E3, E6 and E12 electrodes was shorter in RW group compared with the Promontory group (p < 0.05). The statistical evaluation of ESRT measurements of E1, E3, E6 found p < 0.001 and E12 electrode p < 0.05 in RW group. ESRT measurements were recorded at lower threshold in the RW group compared with the Promontory group. Conclusion: The duration of electrically stimulation thresholds were shorter in RW group. ESRT measurements were recorded at lower threshold in the RW group compared with the Promontory group. RW insertion offers best electrically stimulation relative to electrode insertion via a promontory cochleostomy. (C) 2011 Elsevier Ireland Ltd.

Yöntem: 2005 Ocak - 2015 Ocak tarihleri arasında cerrahi geçiren15 hastanın verileri geriye dönük incelendi. Bütün hastalar yüksek rezolüsyonlu temporal tomografi, House-Brackmann derecelendirmesistemi, elektrodiagnostik testler elektromiyografi ya da elektronörografi) ile değerlendirilmiştir. Bulgular: Çalışmaya yaş ortalaması 20.56 (aralık: 2-59) yıl olan 8 kadın ve 7 erkek hasta katılmıştır. Hastaların tümüne transmastoid yolla fasiyal dekompresyon uygulanmıştır. Sonuç: Transmastoid yaklaşım fasiyal sinir birinci dirseği ve digastricridge arasında hasar olanlarda uygun olmaktadır. Postoperatif elektromiyografi bulgularındaki orbikularis okuli kasındaki amplitüd artışıklinik iyileşme öncesinde sinirdeki iyileşmenin anlamlı indikatörüolarak bulunmuşturÖğe Treatment of Congenital Choanal Atresia via Transnasal Endoscopic Method(Lippincott Williams & Wilkins, 2017) Gulsen, Secaattin; Baysal, Elif; Celenk, Fatih; Aytac, Ismail; Durucu, Cengiz; Kanlikama, Muzaffer; Mumbuc, SemihObjectives: Congenital choanal atresia (CCA) is a very rare abnormality of the nose, but in the case of bilateral presence, it becomes a life-threatening malformation. Various surgical treatment options, such as transpalatal, transseptal, and open rhinoplasty techniques, as well as the transnasal approach, have been defined for the repair of CCA. In this study, the authors intended to evaluate the outcomes of transnasal endoscopic surgery for CCA, and stent implementation's impact on surgical success. Methods: Patients who were admitted to the Otorhinolaryngology Department of Gaziantep University and patients who had not undergone CCA surgery before were included in the study. Patients who underwent transnasal endoscopic choanal atresia surgery (TECAS) were advised to have regular nasal endoscopic examinations performed at check-ups; after a 6-month follow-up period, surgical results were evaluated concerning whether stenosis had occurred or not. Results: Of the 48 patients who underwent TECAS after a minimum 6-month follow-up period, 34 of patients revealed no stenosis, so the overall surgical success rate was 70.8%. Fourteen (29.2%) patients who underwent TECAS developed stenosis and required revision surgery. Conclusions: Transnasal endoscopic choanal atresia surgery is the most preferred approach for CCA repair and has many advantages, such as excellent vision, shorter operative time, minimal bleeding, and minimum complication. Despite advances in endovision systems and surgical instruments, stenosis is the most challenging problem after TECAS, so new treatment strategies should be developed to prevent stenosis.
