“…Unfortunately, many of those drugs present undesirable adverse effects, which makes their use in clinical practice unviable (3,6). Therefore, a new research field using nonpharmacological agents such as acupuncture and electroacupuncture (13,14), pulsed electromagnetic energy (15), low-power lasers (16)(17)(18), monophasic electrical currents (6,7,19) and biphasic electrical currents (8,14,20) has emerged.…”

The aim of this study was to determine the role of transcutaneous electrical nerve stimulation (TENS) in the viability of random skin flaps. In 30 Wistar-EPM rats, a random 10×4 cm skin flap was raised and a plastic barrier was interposed between the flap and its bed. Immediately after surgery and for two subsequent days, the rats in group 1 (the control group) were anesthetized for 1 h with the electrodes positioned in the base of the flap and without the administration of the electric stimulus. The rats in group 2 (the treatment group) were submitted to TENS for 1 h immediately after the surgery and for two subsequent days. The percentage of necrotic area (averages of 43.11% in the rats in group 1 and 23.52% in the rats in group 2) was calculated on the seventh postoperative day in both groups. Statistical analysis proved that TENS was more efficient in increasing random skin flap viability than was the method used in the control group.Key Words: Electrical stimulation; Flaps; Rats; Viability Effet de la neurostimulation transcutanée sur la viabilité de lambeaux cutanés choisis au hasard chez des rats RÉSUMÉ : L'étude visait à déterminer le rôle de la neurostimulation transcutanée dans la viabilité de lambeaux cutanés choisis au hasard. Nous avons d'abord soulevé un lambeau cutané de 10 cm sur 4 cm chez 30 rats Wistar-EPM, puis inséré une pellicule de plastique entre le lambeau et son lit. Immédiatement après l'intervention et pendant les deux jours qui ont suivi, nous avons anesthésié les rats du groupe 1 (groupe témoin) pendant une heure et posé des électrodes à la base du lambeau sans toutefois procéder à l'électrostimulation, tandis que nous avons soumis les rats du groupe 2 (groupe expérimental) à la neurostimulation transcutanée pendant une heure. Sept jours après l'intervention, nous avons calculé le pourcentage de zones nécrosées dans les deux groupes (moyennes de 43,11 % chez les rats du groupe 1 et de 23,52 % chez les rats du groupe 2). D'après l'analyse statistique, la neurostimulation transcutanée s'est avérée plus efficace que la méthode utilisée dans le groupe témoin pour accroître la viabilité des lambeaux cutanés choisis au hasard.

“…The studies found in the literature dealing with this topic used lasers operating at wavelengths of 632.8 5,7,9 , 660 19 and 830 nm 3,4,6,8 , and emitting continuous light (Table 3). In the present study, the increase in survival observed in irradiated skin flaps agrees with previous studies [19][20][21][22] , except for Smith, 9 who did not find any significant effect in the use of laser therapy.…”

“…Furthermore, the use of "energy delivered to the tissue" instead of "energy density" as a parameter for analysis may be necessary since many studies [3][4][5][6][7][8] show apparent contradictions in the results when the parameter energy density is evaluated. The World Association for Laser Therapy (WALT) 29 recommends on their website the use of energy dose delivered to the tissue as a dosimetric parameter in the treatment of pain.…”

PURPOSE: To investigate the effects of different low-level laser therapy (LLLT) doses on random skin flap rats. METHODS: Forty Wistar rats were randomly divided in four groups. The control group (CG) was not irradiated. The experimental groups were irradiated with a diode laser 670 nm with different energies per point: group 2 (G2) with 0.06 J; group 3 (G3) 0.15 J and group 4 (G4) 0.57 J. The three groups were irradiated in 12 equally distributed points in the cranial skin flap portion. They were submitted to the irradiation during the immediate, first and second postoperative days. The necrosis area was evaluated in the seventh postoperative day. RESULTS: The CG shows 49.35% of necrosis area in the skin flap; G2, 39.14%; G3, 47.01% and G4, 29.17% respectively. There was a significantly difference when G4 was compared with CG`s skin flap necrosis area. CONCLUSION: The low-level laser therapy diode 670 nm with 0.57 J energy per point increases the survival in randomic skin flap rats.

“…The Ohshiro clinic, in conjunction with Japan Medical Laser Laboratory has developed new applications of laser treatment since 1975 mainly in the field of plastic surgery (1)(2)(3)(4)(5) . Among the achievements of the 30 years experience using lasers are the treatment of senile flecks, rhytides and laser hair removal with HLLT, and a wide variety of indications for LLLT, ranging from pain attenuation (6)(7)(8) , enhancement of wound healing (9)(10) , alleviation of allergic symptoms (11)(12)(13) and female infertility (14)(15) . In the course of 30 years, the authors have conducted many studies on LLLT including an experiment with Senbai Hospital demonstrating the penetration depth of laser light using the Rand radiographic phantom (16) and have also also demonstrating increased cerebral blood flow following LLLT (17)(18) using SPECT and Doppler ultrasound, hence proving that proximal priority treatment (19)(20) is fast and effective.…”

The authors have over 30 years experience of treatment with lasers, more than 25 of which have been with low reactive-level laser therapy. (LLLT) Based on our experience, we have continuously attempted to develop new treatments and broaden the clinical application of lasers. Many patients receiving LLLT for an entity other than sight problems have spontaneously described a sense of increased visual acuity following their treatment, and the present study was designed to see if there was in fact, any effect of LLLT on vision. Six healthy adult subjects aged 56~68 years old, were treated with LLLT according to the proximal priority theory (PPT). The subjects' close range, far range visual acuity and astigmatism were examined prior to, one hour after and 24 hours after LLLT. The laser hardware used in this experiment was the OhLase HT2001 (Japan Medical Laser Laboratory, Tokyo, Japan) and the Screenoscope (Topcon, Tokyo, Japan). A high rate of improvement was seen for both close range and far range visual acuity but a particularly noteworthy improvement rate of 91.7% was seen at examination for far sightedness immediately after LLLT. LLLT in the field of ophthalmology is promising and further controlled studies carried out by ophthalmologic specialists in larger patient groups may yield new indications for LLLT in this field.
