Better wound healing and less postoperative pain with laser procedures compared with the same procedure performed with the cold scalpel or with electrothermy were reported by those who first used the surgical laser in the late 1960’s and early 1970’s, which was an added beneficial component associated only with laser surgery compared with conventional methodology. This was obviously a photo-med...

Continuum robots have shown astounding abilities in the medical field as numerous robotized devices have emerged. For instance, colonoscopes, arthroscopes, catheters, endoscopes, and other medical tools have been developed [1]. Their ability to navigate through complex anatomy and narrow spaces represent the attractive features of continuum robots. We foresee to improve their usefulness for Min...

PURPOSE To explore the relationship between ablation parameters of myopic laser surgery and measurement area of wavefront aberration (WA) with Hartmann-Shack wavefront sensor. METHODS 58 subjects undergone myopic laser surgeries and 74 uncorrected myopic subjects were enrolled in this experiment. The laser ablation parameters were obtained from surgical records, which included spherical error...

It is commonly accepted that radiotherapy is a first choice for treatment of T1 glottic cancer. However, side effects caused by irradiation are sometimes troublesome to a patient and to a physician. Among side effects, oncogenic problem and late radiation change are most undesirable and may become fatal. Hence, we avoid radiation therapy especially for younger aged patients. We prefer surgical ...

Clinicians always find it difficult to treat hypertrophic scars and keloids. Various treatment modalities are available. Intralesional corticosteroids, topical applications, cryotherapy, surgery, laser therapy, and silicone sheeting are the widely used options. Radiation therapy can also help in cases of recalcitrant keloids. Most recently, pulsed-dye laser has been successfully used to treat k...

PURPOSE Identify ideal profiles in patients undergoing to photorefractive laser surgery with the aid of an automated pupillometry and psychometric analysis of patients with visual function questionnaire (VQF 25). METHODS Seventy-seven patients undergoing photorefractive laser surgery laser (LASIK) were analyzed with the aid of an automated digital pupillometer based on an infrared camera coup...

The objective of our study was to evaluate a surgical method of management of patients with hidradenitis suppurativa (HS), using a CO2 laser technique for stepwise horizontal vaporization and peroperative monitoring of the removal of diseased tissue. Twenty-four patients were selected for treatment, 21 women and three men, who had suffered from HS for a mean of 13 years (range 1-28 years) and e...

A comparative evaluation of low-level laser and CO(2) laser therapies was performed, for the treatment of oral lichen planus (OLP). In a randomized open clinical trial, 28 patients with 57 lesions were randomly assigned to two groups. One group received CO(2) laser therapy, the other received low-level laser therapy (LLLT) for 5 sessions every other day. Participants were examined before the tr...

OBJECTIVE The KTP laser has become commonplace in transoral head and neck surgery. The interactions of this laser with commonly used supplies in transoral surgery have not been formally examined. This study evaluates the effects of the KTP laser on surgical supplies. STUDY DESIGN Experimental study. SETTING The study was conducted in an empty operating room at a university-affiliated medica...

OBJECTIVE To compare voice quality after radiotherapy or endoscopic laser surgery in patients with similar T1a midcord glottic carcinomas according to a validated multidimensional protocol. DESIGN Retrospective cohort study. SETTING University cancer referral center. PATIENTS Two cohorts of consecutive patients willing to participate after treatment for primary T1a midcord glottic carcino...
