“…We also had similar results to those of Wilden [15] with 67% improvement and to those of Marti's [24] study of 18 patients with full improvement in 61%, moderate improvement in 33%, and minor improvement in 6%. Mioc and Mycek [25] selected patients for laser-based therapies in otolaryngology and with high performance improvement. Similarly, Juberg [26] in Norway demonstrated that 87% of their patients reported noticeable improvement and 60% reduction of more than 40% of symptoms as well as no change in 13% of patients.…”

Objective. The objective of the study was to investigate the effectiveness of low-level laser therapy (LLLT) in treating patients who were suffering from long-term complaints of tinnitus with well-understood etiology and who were not responding to conventional therapy in Qatar. Design. This is a prospective clinical study conducted during the period from May 2010 and February 2011. Setting. Audiology Clinic, Outpatient Department, Hamad General Hospital. Subjects and Methods. The study included 65 patients aged 15–76 years with chronic unilateral or bilateral tinnitus with a minimum duration of illness of one year. The investigation included 101 ears of 65 patients. A 5 mW laser with a wavelength of 650 nm was applied transmeatally for 20 minutes once daily for 3 months. The study was based on a face-to-face interview with a designed questionnaire that recorded the diagnosis of patients, clinical evaluation and audiometric test results, and side effects of low-level laser therapy (LLLT) and scored their symptoms loudness on five-point scale every two weeks. A decrease of one scale point regarding the loudness duration and degree of annoyance of tinnitus was accepted to represent an improvement; at the same time, a pure tone audiometric test was carried out and the results recorded. In addition, a record of the side effect was taken. Results. Over half of the patients (56.9%) had some form of improvement in their tinnitus symptoms. Mild improvement was reported in 33.8% of patients, moderate improvement was reported in 16.9%, and full improvement was reported in 6.15%. Of the patients who reported dizzy spells as a symptom of their tinnitus condition, 27.7% reported mild improvement and 16.9% reported full improvement. Common side effects of LLLT were noted among 20% of patients; however, all of them were mild and disappeared within a few days. Conclusion. Low-level laser therapy was found to be useful for treatment of chronic tinnitus.

“…Common laser assisted procedures include stapes footplate perforation, pharyngo-laryngeal tumor surgery, and turbinate reduction. [2][3][4] Despite their established effective use in surgery, conventional lasers have the potential to cause significant tissue injury. It is imperative that the surgeon is cognizant of the complex laser-tissue interactions that may occur as a result of photochemical, photothermal, photomechanical, and photoionizing effects.…”

Objectives/Hypothesis: Conventional lasers ablate tissue through photothermal, photomechanical, and/or photoionizing effects, which may result in collateral tissue damage. The novel nonionizing picosecond infrared laser (PIRL) selectively energizes tissue water molecules using ultrafast pulses to drive ablation on timescales faster than energy transport to minimize collateral damage to adjacent cells. Study Design: Animal cadaver study. Methods: Cuts in porcine laryngeal epithelium, lamina propria, and cartilage were made using PIRL and carbon dioxide (CO₂) laser. Lateral damage zones and cutting gaps were histologically compared. Results: The mean widths of epithelial (8.5 μm), subepithelial (10.9 μm), and cartilage damage zones (8.1 μm) were significantly lower for cuts made by PIRL compared with CO₂ laser (p < 0.001). Mean cutting gaps in vocal fold (174.7 μm) and epiglottic cartilage (56.3 μm) were significantly narrower for cuts made by PIRL compared with CO₂ laser (P < 0.01, P < 0.05). Conclusion: PIRL ablation demonstrates superiority over CO₂ laser in cutting precision with less collateral tissue damage

“…However, the pilot studies show potentially promising results. [152][153][154][155][156][157][158][159] The area in which lasers are most commonly and successfully used in nasal surgery are in patients who have persistent recurrent epistaxis due to intranasal hereditary hemorrhagic telangiectasias (HHT). HHT is an autosomal dominant condition of the vascular tissue that presents in a person at the ages of 20-40.…”

I love you all.vii A refreshing trait of this book about lasers in dermatology is that it is the first in years, to place this topic within the broader perspective of other medical specialties. Almost immediately after the first laser was created in 1960, a handful of visionary physicians recognized that this extremely powerful source of light might have surgical applications. Those pioneers practiced in three organ systems openly accessible for light exposure -ophthalmology, dermatology, laryngology. These are still the specialties that rely heavily on surgical lasers (with the addition of urology, thanks to laser lithotripsy and prostatectomy). By far, dermatologists have a greater variety of therapeutic lasers than any other medical group, while lagging behind in other aspects of laser medicine.How did we get such a wide, almost dazzling, variety of treatment lasers in dermatology? (Because, we need them for different uses in various practice settings; lasers are the most tissue-specific surgical tools in existence.) Do we really need so many? (Well, we need most all of them. Only a few are interchangeable.) Are the mechanistic, clinical, safety, ethical and practice-related chapters of this book worthy of study? (Yes.) Can't we just learn which buttons to push, in courses provided by the more reputable device manufacturers just after a laser is purchased? (This approach is foolish beyond words, yet such fools exist. You may encounter them, and some of the patients they have harmed. Even more foolish are those who purchase a used laser and start using it without any training whatsoever.)Another asset of this text is its practicality, whether you use lasers or not. If you get hooked on laser dermatology please talk to your colleagues, and attend bona fide laser medical conferences that include your particular clinical interests, in which you are free to ask questions of faculty who are not trying to sell something. Pay close attention to the quality and source of clinical evidence regarding safety and efficacy of a particular laser device. There is no substitute for hands-on training, which cannot be obtained i...
