    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, Semih
    Objectives: 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.

    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, Semih
    Objectives: 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.
