A tri-axial HTS power cable has been proposed and developed to reduce the number of HTS wires because it has copper shield instead of HTS shield. However, it has a drawback which is an inherent imbalance problem due to an asymmetry configuration in the cable. The authors designed a 22.9 kV/50 MVA class tri-axial HTS cable. The inherent imbalance problem of the three-phase currents in the tri-ax...

OBJECTIVES The aim of this study was to evaluate anatomic/audiologic outcomes of cartilage tympanoplasty with island technique and compare the results with the results of temporalis fascia tympanoplasty. PATIENTS AND METHODS The charts of 40 patients who underwent surgery for primary type 1 tympanoplasty either with perichondrium-cartilage (12 males, 11 females; mean age 29.7 years; range 12 ...

INTRODUCTION Tympanoplasty is a standard procedure to repair tympanic membrane perforation. The aim of this study is to evaluate the results of tympanoplasty (hearing improvement and tympanic membrane closure rate) in patients suffering from chronic perforation of the tympanic membrane by considering the prognostic factors. MATERIALS AND METHODS In a prospective study, based on the results of...

In our otological practice, we prefer sliced tragal cartilageperichondrium grafting for reconstruction of the tympanic membrane perforations. In an attempt to reduce residual and recurrent perforations in our series of cartilage tympanoplasty using sliced tragal cartilage perichondrium composite graft, we reinforce tragal cartilage with temporalis fascia in large perforations. Aim: The purpose ...

Objective: To compare temporalis muscle fascia and full thickness tragal cartilage in type 1 tympanoplasty. Study design: Retrospective clinical chart review. Subjects and methods: In total, 247 patients (157 male, 90 female; average age of 33.67±13.07 years, range 18 to 65 years) who had been underwent type 1 tympanoplasty in our clinic were included in this study. Demographics, anatomical and...

OBJECTIVE To report a novel tympanoplasty modification for anterior tympanic membrane perforation closure. MATERIALS AND METHODS A prospective study on 13 patients who underwent inferior tympanoplasty between December 2008 and May 2011 was carried out. In our technique, an inferior rather than a posterior flap is raised and the graft is laid from the inferior direction to obtain better access...

OBJECTIVE To assess middle ear aeration after total mastoid obliteration using bone pate and hydroxyapatite performed at the second stage of intact-canal-wall (ICW) tympanoplasty. STUDY DESIGN Retrospective study. SETTING Tertiary referral hospital. PATIENTS Forty-two ears with cholesteatoma underwent the obliteration. Computed tomography (CT) scan 1 week before the second-stage operation...

OBJECTIVES To evaluate the efficacy of combined antistaphylococcal and antipseudomonal preoperative antibiotics for preventing surgical site infections following tympanoplasty and mastoidectomy with contaminated cholesteatoma. STUDY DESIGN Retrospective chart review. METHODS Medical records of patients who underwent tympanoplasty ± mastoidectomy for cholesteatoma were reviewed. Only cases c...

Purpose: The aim of this study was to evaluate the results endoscopic butterfly tympanoplasty in perforations that involve ossicular chain pathologies.
 Materials and Methods: We assessed outcome modified 29 patients. included those with large tympanic membrane covering manubrium malleus has pathologies, operated via transcanal tympanoplasty. 
 Results: closure rate 89.7% (26 ears). m...
