ObjectiveMicrocirculation and oxygen supply in cervical skin were measured with an optical, noninvasive method in patients with or without radiotherapy before neck dissection. The course of wound healing was monitored after the surgical procedure to identify predictive factors for postoperative wound healing disorders.Study DesignTissue spectrophotometry and laser Doppler flowmetry were used to determine capillary oxygen saturation, hemoglobin concentration, blood flow, and blood velocity at 2-mm and 8-mm depths in the cervical skin of 91 patients before neck dissection in a maxillofacial unit of a university hospital in Munich, Germany. Parameters were evaluated for differences between patients with irradiation (24) and without (67) and patients with wound healing disorders (25) and without (66) (univariate or multivariate statistical analyses).ResultsVelocity at 2 mm was lower in irradiated skin (PÂ = .016). Flow at 2 mm was higher in patients with wound healing disorders (PÂ = .018).ConclusionsHigh flow values could help to identify patients at risk for cervical wound healing disorders.
