ABSTRACT Background: Osteoid osteoma is a benign bony neoplasm and its classic treatment is surgery. In the r ecent decades percutaneous laser therapy was suggested to be replaced by surgery. In this study we have reviewed the results of the first applications of interstitial laser photocoagulation (ILP) for treatment of osteoid osteoma in Iranian patients. Materials and Methods: In this case s...

INTRODUCTION Diode laser with wavelengths ranging from 810 to 980 nm in a continuous or pulsed mode was used as a possible instrument for soft tissue surgery in the oral cavity. DISCUSSION Diode laser is one of laser systems in which photons are produced by electric current with wavelengths of 810, 940 and 980nm. The application of diode laser in soft tissue oral surgery has been evaluated fr...

Background and Objective: Cataract is one of the most common causes of blindness in the world, and posterior capsular opacification (PCO) is the most common complication after cataract surgery. Nd: YAG laser posterior capsulotomy is a standard method for the treatment of PCO. The aim of this study was to investigate the effects of Yas laser capsulotomy on anterior segment parameters and lenticu...

SUMMARY laser operate on the principle that excited atoms can be stimulated to emit photons, Resulting in a Markedly amplified light that possesses the Unique properties of coherence, Monochromacy and high Intensity. The Nature of this light allows precise alteration of tissues, primarily by photocoagulation and disruption which has been Utilized in several forms of surgery.

The introduction of femtosecond lasers to cataract surgery has been the major disruptive technology introduced into ophthalmic surgery in the last decade. Femtosecond laser cataract surgery (FLACS) integrates high-resolution anterior segment imaging with a femtosecond laser allowing key steps of cataract surgery to be performed with computer-guided laser accuracy, precision, and reproducibility...

Introduction  Diode laser is a new alternative in stapes surgery for otosclerosis. The present study is the first to compare the short-term results of the surgery performed using diode laser to those obtained through the conventional fenestration technique. Objective  To use audiometry to establish a comparative analysis between the functional results obtained through surgery for otosclerosis u...

BACKGROUND To evaluate the oncologic effectiveness of transoral laser surgery of supraglottic cancer, we compared a group of patients treated with laser surgery, with a stage-matched group treated with a transcervical approach. METHODS Twenty-six patients who underwent laser surgery were retrospectively compared with 26 patients who underwent a transcervical approach. In both groups, the pati...
