Barrel-shaped design of the forearm free flap for lower lip reconstruction: a pilot case-control study.

ABSTRACT:

Background

Radial free forearm flaps is indicated patients with total or near-total defects in their lower lip. The purpose of our study was to evaluate a simple and effective barrel-shaped design of the radial free forearm flap for lower lip reconstruction and to compare its clinical outcomes with those of a conventional rectangular shaped free forearm flap.

Methods

Twenty-two patients with a lower lip carcinoma who underwent radial forearm free flap reconstructive surgery were enrolled in this study between January 1, 2012, and December 31, 2017. A barrel-shaped design of radial forearm free flap for reconstruction was used in 8 patients (case group), and a rectangular design was used in 14 patients (control group). The patients' quality of life was evaluated preoperatively and postoperatively in all the patients using the European Organization for Research and Treatment of Cancer Quality of Life (EORTC-HN35) questionnaire. We analyzed the differences in the EORTC QLQ-HN35 scores pre- and postoperatively between the case and control group.

Results

The patients in the case group had better outcomes in swallowing, speech, social eating, social contact, and dry mouth than the control group at 1-year follow-up (P?ConclusionsThe use of a barrel-shaped design free forearm flap for lower lip reconstruction is an effective procedure and can achieve better results than the use of rectangular free forearm flap.

Project description:Both free posterior tibial flap (FPTF) and free radial forearm flap (FRFF) are commonly used for head and neck defects. They have many similarities in embryology, histology, and anatomy, but their advantages and disadvantages in head and neck repair have not been fully recognized. This study aimed to compare the cadaveric anatomy and clinical application of FPTF and FRFF for the reconstruction of head and neck defects after tumor resection. Anatomical dissection was performed on 10 fresh adult cadavers. The general characteristics of both flaps and the sites of recipients and donors were collected. A total of 31 and 25 patients underwent FPTF and FRFF construction, respectively. The patient medical records were assessed to obtain the clinical characteristics. Characteristics of the flap such as size, pedicle length, and clinical process data were collected and compared. The appearance, sensory disturbance, and effect on quality of life and daily activity were evaluated. The posterior tibial artery was present and observed in all patients. The posterior vascular pedicle was longer than the radial artery. There was no difference between the diameters of arteries of FPTF and FRFF; however, the diameters of their veins differed. In terms of flap characteristics, FPTF was significantly larger and had a longer vascular pedicle than FRFF (40.68±11.07 vs. 53.77±29.02 cm2, P=0.03; 8.48±1.66 vs. 11.10±2.39 cm, P=0.00). Patients in the FPTF group had a significantly shorter total hospital stay (FRFF: 26.48±8.33 d; FPTF: 18.58±6.68 d), postoperative hospital stay (FRFF: 17.60±5.53 d; FPTF: 10.94±3.62 d), and flap harvest time (FRFF: 87.00±20.92 min; FPTF: 65.00±17.56 min) than FRFF group. There were far more complications of the donor site in the FRFF group than in the FPTF group. Also, according to the patients' subjective evaluations of the donor site, FPTF was superior to FRFF (P=0.00). FPTF is a reliable alternative to FRFF for head and neck reconstruction. These techniques share similar certain embryogenesis and anatomical characteristics but FPTF possesses unique aesthetic and clinical application advantages.

Project description:BACKGROUND:Fluid management of the surgical patient has undergone a paradigm shift over the past decade. A change from 'wet' to 'dry' to a 'goal-directed' approach has been witnessed. The fluid management of patients undergoing free flap reconstruction is particularly challenging. This is typically a long operation with minimal surgical stimulation, and hypotension often ensues. The use of vasopressors in these cases is contraindicated to maintain adequate flow to the flap. Hypotension is often treated with intravenous fluid boluses. However, aggressive fluid administration to maintain adequate blood pressure can result in flap edema, venous engorgement and, ultimately, flap loss. OBJECTIVE:The primary objective of the present study was to determine whether goal-directed fluid therapy, titrated to maintain stroke volume variation ?13%, with the use of an arterial pulse contour device results in improved postoperative cardiac index (CI) and stroke volume index (SVI) with reduced amounts of intravenous fluid. The primary end points studied were CI, SVI and cumulative crystalloid/colloid administration. METHODS:Twenty female patients undergoing simultaneous microvascular free flap reconstruction immediately following mastectomy were studied. Preoperative and intraoperative care were standardized. Each patient received intra-arterial blood pressure monitoring. In all patients, cardiac output measurement occurred throughout the intraoperative period using the arterial pulse contour device. Control patients had their fluid administered at the discretion of the anesthesiologist (blinded to results from the cardiac output device). Patients in the intervention group had a baseline crystalloid infusion of 5 mL/kg/h, with intravenous colloid boluses to maintain a stroke volume variation ?13%. RESULTS:There was no difference in heart rate or mean arterial pressure between groups at the end of the operation. However, at the end of the operation, the intervention group had significantly higher mean (± SD) CI (3.8±0.8 L/min/m(2) versus 3.0±0.5 L/min/m(2); P=0.02) and SVI (51.4±2.4 mL/m(2) versus 43.3±2.3 mL/m(2); P=0.03). This improved CI and SVI was achieved with similar amounts of administered intraoperative fluid (5.8±0.5 mL/kg/h versus 5.0±0.7 mL/kg/h, control versus intervention). The intervention group required less postoperative fluid resuscitation during the early postoperative period (total fluid administered from end of operation to midnight of the operative day, 6.4±1.9 mL/kg/h versus 10.2±3.3 mL/kg/h, intervention versus control, respectively, P<0.01). DISCUSSION:Goal-directed fluid therapy using minimally invasive cardiac output monitoring resulted in improved end-operative hemodynamics, with less 'rescue' fluid administration during the perioperative period.

Project description:The blood supply pattern of the partial-thickness musculomucosal pedicle flaps is different from the traditional Abbe flap. The arterial blood supply and venous drainage are highly reliable during clinical practice.To describe the reconstruction of the philtrum in the cross-lip flap transfer using nasolabial muscle tension line group reconstruction.From January 1, 2014, through June 31, 2015, a total of 6 patients with upper lip defect were treated with philtrum reconstruction in the same stage of the split cross-lip flap transfer at the Plastic Surgery Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China. These patients underwent reconstruction of the philtrum by nasolabial muscle tension line group reconstruction. The patients were compared with a randomly chosen group of 5 individuals without upper lip defects by measuring the 3-dimensional scans.In the patient group, the split flap was elevated from the posterior portion of the oris orbicularis muscle after the inferior labial arteries were divided. Then the partial-thickness flap was rotated 180° horizontally and inverted 180° upward to the upper lip defect. The philtrum was reconstructed using the nasolabial muscle tension line group reconstruction.Three-dimensional scans were performed from the 2-month to 28-month revisits.A total of 11 individuals were included in the study: 6 in the patient group (mean [SD] age, 17.0 [4.8] years; 2 [33.3%] female and 4 [66.7%] male) and 5 in the control group (mean [SD] age, 15.2 [6.0] years; 2 [40.0%] female and 3 [60.0%] male). In the patient group, 5 of 6 musculomucosal pedicle flaps were viable. A stable philtrum with philtral ridge and philtral dimple was reconstructed on the 5 flaps. The shape of the philtrum was natural according to the 3-dimensional scan measurement. One flap partially necrosed, and the scar retraction was severe postoperatively.The blood supply of the partial-thickness cross-lip flap was from the small vascular network of the lower lip. It is reliable to reconstruct a philtrum in this stage of flap transfer. A complete philtrum structure can be reconstructed by applying muscle tension on the flap.4.
