Expanded forehead flap in Asian nasal reconstruction.

ABSTRACT: This article reviewed our experience of Chinese nasal reconstruction over 12 years and evaluated the effect of expanded forehead flap both aesthetically and functionally. The special skin type and other anatomic features of Chinese patients was understood thoroughly during the treatment. This article thus catered for the need of multiracial nasal reconstruction. We analyzed existing clinical data and demonstrated a typical case in detail. The postoperative result supported our strategy which advocated the extensive application of expanded forehead flap, together with flip scar flap as the internal lining. The features of Chinese patients also prompted the use of costal and auricular cartilage. Emerging technology like 3D-printing would benefit nasal reconstruction from more aspects.

Project description:ImportanceParamedian forehead flaps are commonly used to reconstruct facial defects caused by skin cancers. Data are lacking on the complications from this procedure, postoperative outcomes, and association of cancer diagnosis with rate of deep venous thrombosis (DVT).ObjectivesThe primary objective was to determine complication rates after paramedian forehead flap reconstruction for defects resulting from resection of facial cancers; and the secondary objective was to determine patient factors and complications that are associated with readmission.Design, setting, and participantsRetrospective cohort study of patients who underwent paramedian forehead flap reconstruction for skin cancer reconstruction from January 1, 2007, through December 31, 2013. Data analysis took place between October 1, 2017, and June 1, 2018.Main outcomes and measuresComplication rates including DVT, emergency department visits, and hospital readmissions.ResultsA total of 2175 patient were included in this study; mean (SD) age, 70.3 (13.4) years; 1153 (53.5%) were men. Postoperative DVT occurred in 10 or fewer patients (≤0.5%); postoperative bleeding in 30 (1.4%), and postoperative infection in 63 (2.9%). Most patients went home on the day of surgery (89.6%; n = 1949), while 10.4% stayed one or more days in the hospital (n = 226). Overnight admission was associated with tobacco use (odds ratio [OR], 1.65; 95% CI, 1.11-2.44), hypothyroidism (OR, 1.93; 95% CI, 1.10-3.39), hypertension (OR, 1.82; 95% CI, 1.29-2.57), ear cartilage graft (OR, 2.20; 95% CI, 1.51-3.21), and adjacent tissue transfer (OR, 1.88; 95% CI, 1.33-2.67). Risk factors strongly associated with immediate return to the emergency department or readmission within 48 hours of surgery included postoperative bleeding (OR, 13.05; 95% CI, 4.24-40.16), neurologic disorder (OR, 4.11; 95% CI, 1.12-15.09), and alcohol use (OR, 7.70; 95% CI, 1.55-38.21).Conclusions and relevanceIn this study, the most common complication of paramedian forehead flap reconstruction was infection. Risk factors for readmission included development of postoperative bleeding, having a neurologic disorder, and alcohol use. Deep venous thrombosis was a rare complication. Because bleeding is a more common complication in this patient population, discretion should be used when deciding to administer anticoagulation medication to low- to medium-risk patients prior to surgery.Level of evidenceNA.

Project description:ImportanceIdentifying factors affecting forehead flap neovascularization during nasal reconstruction surgical procedures using quantitative dynamics of fluorescence from indocyanine green angiography may be associated with reduced vascular complications.ObjectivesTo identify quantifiable forehead flap perfusion measures using indocyanine green angiography during nasal reconstruction procedures and to evaluate clinical factors associated with neovascularization.Design, setting, and participantsRetrospective cohort study of 71 patients at a tertiary referral center of Stanford University, Stanford, California, between January 1, 2010, and March 31, 2018, undergoing forehead flap nasal reconstruction surgery with flap perfusion assessed by indocyanine green angiography.ExposuresIndocyanine green angiography was performed intraoperatively to record forehead flap neovascularization during the second stage of nasal reconstruction surgery after temporary clamping of the pedicle.Main outcomes and measuresWith use of quantifiable data of fluorescence dynamics, flap perfusion in association with a reference point in the cheek after pedicle clamping was assessed by 2 methods: (1) ingress (arterial inflow) and egress (venous outflow) flap-to-cheek ratio and (2) flap-to-cheek perfusion (fluorescence) ratio at 3 time points (midpoint of indocyanine green flap inflow, maximum fluorescence [peak], and midpoint of indocyanine green flap outflow) and their calculated mean. Association of the perfusion measures with patient and procedural factors was performed using linear regression models.ResultsOf the 71 patients included in the study, 43 (61%) were men; the mean (SD) age was 71.1 (11.0) years. The mean (SD) flap-to-cheek inflow ratio was 0.48 (0.40), peak fluorescence ratio was 0.59 (0.34), and outflow ratio was 0.88 (0.42). The calculated mean (SD) flap-to-cheek perfusion ratio of these measures was 0.65 (0.35). The mean (SD) flap-to-cheek ingress ratio was 0.54 (0.36) and egress ratio was 0.65 (0.98). With use of a multivariable regression model, the time between stages was positively associated with flap-to-cheek ingress ratio (β, 0.015; 95% CI, 0.001 to 0.030), and cartilage grafting was negatively associated with flap-to-cheek outflow ratio (β, -0.240; 95% CI, -0.472 to -0.008).Conclusions and relevanceThe findings suggest that indocyanine green angiography is an effective method to quantify relative neovascularization perfusion of forehead flaps. Future applications may include the use of this technology to aid in early flap division and ensure adequate perfusion among high-risk patients.Level of evidenceNA.
