INTRODUCTION Perioperative irradiation is often combined with spine tumor surgery. Radiation is known to be detrimental to healing process of bone fusion. We tried to investigate bone fusion rate in spine tumor surgery cases with perioperative radiation therapy (RT) and to analyze significant factors affecting successful bone fusion. METHODS Study cohort was 33 patients who underwent spinal t...

Background: Secondary alveolar bone graft has been widely used for the closure of maxillary bone defects in patients with cleft lip and palate (CLP). However, the log-term stability of grafted bone in detail remains unclear. Purpose: To evaluate the nature of longitudinal changes in the grafted bone from autogenous iliac bone in patients with CLP for more than 2 years after the surgery. Methods...

PURPOSE To report a case of pterygium surgery with conjunctival autograft followed by focal necrotizing scleritis due to foreign body entrapment in the scleral bed. CASE REPORT/RESULTS This is a case report of a 76-years-old male patient who underwent nasal pterygium surgery and developed focal necrotizing scleritis secondary to foreign body entrapment under conjunctival autograft. One month ...

Introduction  Myringoplasty is a commonly performed otologic surgery. Objectives  The objective of this study is to evaluate the effect of prognostic factors like - size, site of perforation, status of operating ear, approach, status of contralateral ear, experience of surgeon, primary or revision myringoplasty, and smoking in graft uptake, as well as to evaluate the hearing results after myrin...

AIM Fat graft migration following spinal cord surgery is an uncommon problem. Only few cases of fat graft migration causing cauda equine syndrome, recurrent sciatica, and root compression following lumbar spine surgery have been reported. We report a case of fat graft migration causing symptomatic cervical cord compression. MATERIAL AND METHODS A 45-years-old male with cervica...

OBJECTIVES Gingival recession can lead to root exposure and discomfort for patients. There are various techniques for root coverage. The aim of this study was to compare the use of gingival unit graft (palatal graft including the marginal gingiva and papillae) with free gingival graft for treatment of localized gingival recession. MATERIALS AND METHODS In this randomized controlled clinical t...

The use of bovine amnion in the urinary tract for reconstructive purposes following ablative surgery in cases of trauma, cancer or infection is now a common practice in urological surgery. To evaluate urinary bladder reconstruction with bovine amniotic membrane (BAM), ten healthy mongrel dogs of either sex weighing 10-40 kg were used. The animals were randomly divided into two groups of fi...

Background: Rejection is the most common cause of late corneal graft failure. The purpose of this study is determining the prevalence, and defining the role of those factors which may affect the risk for rejection. Methods: The study was conducted on all patients who had penetrating keratoplasty without immunosuppressive therapy with at least 1 year follow up. Demographic status, cause of graft...

PURPOSE The objective of this study was to clinically evaluate the use of OSTEON as a sinus graft material and to measure the effect of healing at 4 and 6 months after surgery. MATERIALS AND METHODS After sinus graft using OSTEON in 17 patients, bone specimens were collected from lateral sinus using 2.0-mm trephine bur at the time of 4 or 6 months after surgery. Histology of the bone specimen...
