Introduction: Myringosclerosis, one of the most common complications of ventilation tube placement, is a kind of tympanosclerosis and is defined as subepithelial hyalinization of the tympanic membrane. There are two arguments in the development of myringosclerosis: inflammation triggering the development of myringosclerosis and free oxygen radicals released during inflammation causing myringosclerosis. Objective: The aim of the present study was to explore the effects on the development of myringosclerosis of mitomycin, which has anti-inflammatory effects, and trimetazidine, which is believed to inhibit free oxygen radicals when given systemically. Materials and Method: The study was carried out on rabbits. Animals were divided into five groups, with six rabbits in each group: three control groups (paracentesis only, paracentesis + tube placement, and no intervention), a trimetazidine group, and a mitomycin group. Mitomycin (0.4 mg/mL) and trimetazidine (20 mg/mL) were applied topically to the tympanic membrane, and the presence and degree of sclerosis were graded histopathologically after Masson's trichrome staining. Results: In the histopathologic examination, sclerosis that developed in the tympanic membranes of rabbits that had undergone paracentesis or paracentesis plus tube application or received trimetazidine was significantly more extensive than sclerosis in the membranes of unoperated animals and those that had been administered mitomycin. Conclusions: Paracentesis in rabbits, independent of tube placement, causes sclerosis of the tympanic membrane. Results show that topical use of mitomycin, due to its anti-inflammatory effect, had alleviating effects on myringosclerosis, whereas topical trimetazidine did not.
Endoscopic Dacryocystorhinostomy With a T-Type Ventilation Tube
(B C decker inc, 2007) Kiroglu, A. Faruk; Cankaya, Hakan; Yuca, Koeksal; Kiris, Muzaffer
Background: The aim of this article is to present a different endoscopic dacryocystorhinostomy technique and its results on patients with blockage of the nasolacrimal drainage system. Methods: Eleven patients (seven female and four male) who had chronic epiphora with the diagnosis of chronic nasolacrimal duct blockage were operated on using T-type ventilation tubes. Oral antibiotics, nasal steroids, oral antihistamines, and antibiotic eyedrops were given to all cases. The ventilation tubes were removed 3 months after surgery. Results: Of 11 cases, 9 patients had unilateral and 2 patients had bilateral blockage. Eleven sides of nine patients were symptom free (85% success rate), and two patients had decreased continuation in complaints. Granulation tissue occurred in two revision patients. Conclusion: Endoscopic dacryocystorhinostomy using a T-type ventilation tube is an easy and cost-effective alternative and has low complication rates in the management of patients with nasolacrimal duct obstruction.

(B C decker inc, 2008) Yuca, Koeksal; Kati, Ismail; Tekin, Murat; Yilmaz, Nebi; Tomak, Yakup; Cankaya, Hakan
Objective: The purpose of this study was to prospectively analyze intensive care unit patients with fibre-optic bronchoscopy assisted percutaneous dilatational tracheostomy by guidewire dilating forceps (GWDF; Griggs percutaneous tracheostomy). Design: Prospective study. Setting: A tertiary care centre. Materials and Methods: Fifty-two critically ill patients (32 men and 20 women), aged 16 to 84 years (mean +/- 6 SD 42 +/- 1.6 years) who required endotracheal intubation for longer than 15 days were consecutively selected to undergo tracheostomy by the GWDF technique. The diagnoses of the patients and intraoperative and postoperative complications were recorded. Results: The patients were mechanically ventilated for an average of 14.8 +/- 1.2 days. The duration of the GWDF technique was 4.9 +/- 1.7/min. Intraoperative complications occurred in 10 (19.2%) patients: hemorrhage in 3 cases, puncture of the tracheal tube in 2 cases, difficult cannulation in 2 cases, difficult dilatation in 1 case, false passage in 1 case, and inadvertent extubation in 1 case. Postoperative complications occurred in three (5.7%) patients, stomal cellulitis in one case, subcutaneous emphysema in one case, and difficult recannulation in the remaining case. Conclusions: Fibre-optic bronchoscopy-assisted percutaneous dilatational tracheostomy by GWDF is a simple and fast technique for inserting a tracheal cannula.
Treatment Modalities in Maxillofacial Fractures: Retrospective Analysis
(Ortadogu Ad Pres & Publ Co, 2009) Kiris, Muzaffer; Yuca, Koeksal; Celebi, Sezgin; Kiroglu, Faruk; Cankaya, Hakan
Objective: Our aim was to analyze patients treated for maxillofacial fractures due to trauma retrospectively and to discuss the results. Material and Methods: The study comprised 138 patients [aged between 2-76 years, (mean age 29.12 +/- 14.79) 102 men, 36 women] who had attended the Department of Otorhinolaryngology, Yuzuncu Yil University Medical Faculty during February 1995-October 2006, with maxillofacial fractures due to trauma. The patients were evaluated retrospectively for etiology, localization, treatment modalities and complications, and results were compared with other studies. Results: Traffic accidents were the most common cause of maxillofacial fractures (34%), followed by falls from high (21%). Distribution of maxillofacial fractures due to trauma were as follows; mandibular fractures in 64.6% and maxillary fractures in 20.2%. Among mandibular fractures, parasymphyseal fractures were the most common by 31.5% and coronoid fractures were the least common with 0.6%. The techniques used for treatment were miniplaque application, arch-bar Gillie's method and condilectomy; miniplaque technique being the most frequently used (67.7%). The most common complication was infection. Seven patients required tracheotomy in the emergency room for respiratory distress was. Conclusion: In this study, techniques and equipments used in the treatment process changed parallel to technological developments. While wire fixation and arch-bar procedures were more frequent in the earlier cases, titanium mini-plaques and microplaques had results that were more favorable with better outcomes and less complications.
