“…Medical applications of thermography are wide [6] and are most often used to investigate a temperature change revealing a possible pathology. These applications include among others the monitoring of skin temperature [7,8], the detection of breast cancer [9,10], skin cancer [11] and inflammation [12]. In the operating room, thermography was investigated for neurosurgical applications [13,14] and plastic breast reconstruction [4].…”

The aim of this study is to investigate static and dynamic infrared (IR) thermography for intra- and postoperative free-flap monitoring following oropharyngeal reconstruction. Sixteen patients with oropharyngeal reconstruction by free radial forearm flap were included in this prospective, clinical study (05/2013-08/2014). Prior ("intraop_pre") and following ("intraop_post") completion of the microvascular anastomoses, IR thermography was performed for intraoperative flap monitoring. Further IR images were acquired one day ("postop_1") and 10 days ("postop_10") after surgery for postoperative flap monitoring. Of the 16, 15 transferred free radial forearm flaps did not show any perfusion failure. A significant decreasing mean temperature difference (∆T: temperature difference between the flap surface and the surrounding tissue in Kelvin) was measured at all investigation points in comparison with the temperature difference at "intraop_pre" (mean values on all patients: ∆T intraop_pre = -2.64 K; ∆T intraop_post = -1.22 K, p < 0.0015; ∆T postop_1 = -0.54 K, p < 0.0001; ∆T postop_10 = -0.58 K, p < 0.0001). Intraoperative dynamic IR thermography showed typical pattern of non-pathological rewarming due to re-established flap perfusion after completion of the microvascular anastomoses. Static and dynamic IR thermography is a promising, objective method for intraoperative and postoperative monitoring of free-flap reconstructions in head and neck surgery and to detect perfusion failure, before macroscopic changes in the tissue surface are obvious. A lack of significant decrease of the temperature difference compared to surrounding tissue following completion of microvascular anastomoses and an atypical rewarming following a thermal challenge are suggestive of flap perfusion failure.

“…Its use is also being investigated in neurosurgical and plastic breast reconstruction. 7,[13][14][15][16][17] Although infrared thermography is an old concept, it has not gained popularity due to its certain limitations. It provides two-dimensional information only pertaining to perforator location and not to entire morphology, unlike CT or magnetic resonance angiography, which give three-dimensional details regarding the entire vascular pattern.…”

Background: Reconstruction using microvascular free flaps has become the standard of care in head and neck cancer surgery, and their success lies in appropriate planning, adequate revascularization, and early detection of flap compromise so that prompt salvage is possible. This study evaluates the role of infrared thermography in the planning, execution, and postoperative monitoring of microvascular flaps in head and neck reconstructions. Methods: This is a single institutional, prospective observational study conducted at a tertiary care hospital in South India for 13 months. Twenty patients were included, and their thermographic images were captured in the preoperative, intraoperative, and postoperative settings using the infrared camera FLIR T400. These images were analyzed along with the Doppler, and clinical monitoring findings in all the settings and the temperature difference were calculated postoperatively. Results: Hotspot perforator marking was made using infrared camera, and perforator marking was made using hand-held Doppler preoperatively, which correlated in 93% of cases. Intraoperatively, flap rewarming was successfully demonstrated in 19 of 20 cases. Postoperatively, flap compromise was observed on infrared thermography during the first 24 hours but not on clinical monitoring in three cases. The temperature difference values recorded were 5.4°C, 2.4°C, and 4.9°C. The mean of temperature difference of the healthy flaps was 1.0°C (range 0.1°C–1.8°C). Conclusion: Infrared thermography provides simple and reliable imaging, which can be used in perforator marking and flap designing preoperatively and checking the flap perfusion and vascular anastomosis patency intra- and postoperatively.

“…We can distinguish from heating or cooling of the examined object Heating can be achieved by halogen lamps [1], microwave [2], ultrasound [3], etc.. Cooling can be performed by applying stream of cold air [4], cold water, ice, vaporous fluids [5] or as in our application the stream of CO2 [6]. In biomedical applications cooling has its special role.…”

This paper presents the assessment of the influence of the CO2 cooling on active dynamic thermography (ADT) and thermal tomography (TT) results. This influence is great enough that one should consider taking it into account while thermal or dynamic parameters estimation. We try to estimate how much the infrared radiation is attenuated by the cloud of the CO2 gas present in front of the IR camera lens.
