Green light photoplethysmography monitoring of free flaps.

BACKGROUND Monitoring strategies have been developed to address the issue of detecting postoperative free flap ischemia in an effort to permit intervention and flap salvage. No one existing noninvasive method has been widely accepted in a clinical setting. Green light photoplethysmography (GLP) uses a diode to transmit green light into a tissue. Reflected light from hemoglobin in dermal capilla...

THE CLINICAL APPLICATION OF PREFABRICATED FREE FLAPS FOR NASAL RECONSTRUCTION

We have found prefabrication of hairless radial forearm free flap to be a useful technique for nasal reconstruction. Prior skin grafting and a suitable period of maturation permits safe, reliable surgery. Its use should be considered in those patients whose forehead tissue is not suitable or in whom appropriate distant flaps are not available, as is often the case with hirsute males.

White light spectroscopy for free flap monitoring.

White light spectroscopy non-invasively measures hemoglobin saturation at the capillary level rendering an end-organ measurement of perfusion. We hypothesized this technology could be used after microvascular surgery to allow for early detection of ischemia and thrombosis. The Spectros T-Stat monitoring device, which utilizes white light spectroscopy, was compared with traditional flap monitori...

Modern Oral Cavity Reconstruction with Free Flaps and Pedicled Flaps

Small defects resulting from tumor ablation can be successfully managed with primary closure (i.e., limited excisions within the oral cavity), sometimes can be left to heal for secondary intention (transoral oropharyngeal/laryngeal/hypopharyngeal resections) or can be resurfaced using skin grafts or small local flaps, but in the majority of the cases the resulting defect requires a flap transpo...

Origin of Infrared Light Modulation in Reflectance-Mode Photoplethysmography

We recently pointed out the important role of dermis deformation by pulsating arterial pressure in the formation of a photoplethysmographic signal at green light. The aim of this study was to explore the role of this novel finding in near-infrared (NIR) light. A light-emitting diode (LED)-based imaging photoplethysmography (IPPG) system was used to detect spatial distribution of blood pulsation...
