## Abstract ## Objectives/Hypothesis: Although acquired nasopharyngeal stenosis (NPS) is frequently attributed to infectious and granulomatous processes, it can also occur secondary to external beam radiation therapy for head and neck cancer. NPS can be treated with local flaps, laser excision, na

The wavelength dependence of the ablation threshold of a variety of tissues has been studied by using a tunable pulsed Co:MgF, laser to determine how closely it tracks the optical absorption length of water. The Co:MgF, laser was tuned between 1.81 and 2.14 pm, a wavelength region in which the absor
## Abstract ## Background and Objective Recently, a new, flexibleβfiber, CO~2~ laser delivery system has been FDAβcleared for clinical use. However, for otologic surgery, no data have been reported correlating power settings to depth of penetration into the otic capsuleβthe bone that covers the in
A retrospective study was carried out to determine the usefulness of the CO, laser in the management of patients with recurrent and metastatic intraabdominal tumors. Twenty-six intraabdominal procedures utilizing the laser were carried out on 24 patients at The Ohio State University between 1984 and
## Abstract A pulsed Er:YAG laser at 2.94 ΞΌm and a superpulsed CO~2~ laser at 10.6 ΞΌm are used to investigate bone ablation applications in otolaryngology. Quantitative measurements of mass removal and the ablation depth of cat skull bone and rat femur are presented with the Er:YAG laser at fluence
