Endotracheal tube ignition during CO2 laser surgery of the larynx.
We report a case of endotracheal tube fire occurring during CO2 laser surgery of the larynx. The ignition of an endotracheal tube was thought to be caused by laser penetration of an unprotected portion of the tube during resection of vocal cord tumour. Fire hazard is inevitable when a laser is used in the path of combustible gases and in the presence of flammable objects. We discuss the methods...
متن کاملTreatment of Advanced Carcinoma of the Larynx and Hypopharynx with Laser Followed by External Radiotherapy
Introduction: Radical laryngeal surgeries for extensive laryngeal and hypopharyngeal tumors often require a permanent tracheostomy, which has an immense impact on the quality of life of patients. A minimally invasive technique such as transoral laser microresection (TLM) followed by radiotherapy can preserve the functions of the voice and swallowing. The aim of this study is to evaluate the ro...
متن کاملDirect autofluorescence during CO2 laser surgery of the larynx: can it really help the surgeon?
Herein we assessed the impact of direct autofluorescence during intraoperative work-up on obtaining superficial free resection margins, identifying new areas of malignant transformation and altering disease-free survival and local control at 3 years in patients submitted to transoral laser surgery (TLS) for early glottic cancer. Prospective cohort evaluation was carried out on the diagnostic ac...
متن کاملCO2 laser surgery: a larynx preservation alternative for selected hypopharyngeal carcinomas.
BACKGROUND Transoral CO2 laser surgery (TLS) has demonstrated good oncologic results and low morbidity in the treatment of selected laryngeal carcinomas, but experience in hypopharyngeal carcinomas (HC) is limited. The aim of this study was to evaluate the usefulness of TLS in the treatment of selected HC. METHODS Twenty-eight patients with HC were treated with TLS and neck dissection. Tumors...
متن کاملcontrol of the optical properties of nanoparticles by laser fields
در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
