Intraoperative vasopressors in head and neck free flap reconstruction.

INTRODUCTION: Historically, there were concerns vasopressors impair free flap outcomes, but recent studies suggest vasopressors are safe. Here we investigate this controversy by (1) evaluating vasopressors' effect on head and neck free-flap survival and surgical complications, and (2) performing soft tissue and bony subset analysis. PATIENTS AND METHODS: Post hoc analysis was performed of a single-blinded, prospective, randomized clinical trial at a tertiary care academic medical center involving patients ≥18 years old undergoing head and neck free flap reconstruction over a 16-month period. Patients were excluded if factors prevented accurate FloTrac™ use. Patients were randomized to traditional volume-based support, or goal-directed support including vasopressor use. Primary data was obtained by study personnel through intraoperative data recording and postoperative medical record review. RESULTS: Forty-one and 38 patients were randomized to traditional and pressor-based algorithms, respectively. Flap survival was 95% (75/79). There was no significant difference between the pressor-based and traditional protocols' flap failure (1/38 [3%] vs. 3/41 [7%], RR 0.36, 95% CI of RR 0.04-3.31, p = .63) or flap-related complications (12/38 [32%] vs. 18/41 [44%], RR 0.72, 95% CI 0.40-1.29, p = .36) Soft tissue flaps had surgical complication rates of 12/30 (40%) and 9/27 (33%) for traditional and pressor-based protocols, respectively. Bony flaps had surgical complication rates of 6/11 (55%), and 3/11 (27%) for traditional and pressor-based protocols, respectively. CONCLUSIONS: Intraoperative goal-directed vasopressor administration during head and neck free flap reconstruction does not appear to increase the rate of flap complications or failures.

Latissimus dorsi myocutaneous free flap for the laryngopharyngectomy defect.

BACKGROUND: Partial or total laryngopharyngectomy defects have traditionally been reconstructed using the radial forearm, anterolateral thigh, or jejunal free flaps. The latissimus dorsi myocutaneous free flap (LDMFF) is an option for high-risk patients with complex laryngopharyngeal ± cutaneous neck defects. METHODS: Retrospective single-surgeon case series from 2017 to 2022. Outcomes were assessed at both the back donor site and head and neck. RESULTS: Twenty-four patients were identified. Flap survival was 100%. There was 1 (4.2%) pharyngocutaneous fistula and 2 (8.3%) tracheo-esophageal peristomal fistulas. At last follow-up, 17 (71%) were sustaining weight on oral intake, and 7 (29%) were G-tube dependent with 4 of these able to do some type of oral intake. Seven (29.2%) had post-operative stricture/stenosis requiring dilation. There were only minor donor site complications, all managed conservatively. CONCLUSIONS: The LDMFF can be a robust reconstructive option, particularly for radiated high-risk patients with complex pharyngeal defects, including skin.

Speech Intelligibility in Patients with Facial Paralysis.

Background: Patients with facial paralysis often report frustration with communication; however, there are limited data regarding intelligibility deficiencies. Objective: To compare speech intelligibility in patients with severe and non-severe facial paralysis, and in patients with or without synkinesis. Methods: Video and audio data were reviewed retrospectively. Groups were stratified as follows: Group A - severe paralysis (Sunnybrook 0-20) without synkinesis; Group B - non-severe (Sunnybrook >20) paralysis without synkinesis; and Group C - non-severe paralysis with synkinesis. Intelligibility was assessed by lay-people and a speech and language pathologist (SLP) using the Frenchay Dysarthria Assessment Version 2 (FDA-2). A receiver operating characteristic (ROC) curve was used to determine a Sunnybrook cutoff for intelligibility. Results: Eighty cases were reviewed with mean age 55.6, 53.8% female. 25.0% were in Group A, 30.0% Group B, and 45.0% in Group C. Lay-people rated 15.0% and the SLP rated 28.7% as having intelligibility deficiency. An ROC curve demonstrated that patients with Sunnybrook ≤18.5 were more likely to have intelligibility abnormality. Conclusion: Patients with Sunnybrook ≤18.5 are more likely to demonstrate intelligibility deficiency. Clinicians with a more trained ear are more likely to identify intelligibility abnormality compared with lay-people. Those with synkinesis are more intelligible compared with those without it.

Prognostic factors associated with achieving total oral diet following osteocutaneous microvascular free tissue transfer reconstruction of the oral cavity.

INTRODUCTION: Osteocutaneous microvascular free tissue transfer (OMFTT) is the current standard in reconstruction of large bony defects of the oral cavity. Although being able to swallow ranks as a top priority for patients undergoing OMFTT, factors associated with achieving an oral diet following surgery remain unclear. We sought to describe the rate of total oral diet achievement, and to identify possible pre-, intra-, and post-operative factors associated with achievement in patients undergoing OMFTT. METHODS: Retrospective review between January 1, 2010 and March 31, 2018 at two tertiary academic centers. RESULTS: 249 patients (67% male, mean age 58 years) met inclusion criteria, with a median follow up of 15 months. Overall, 142 (57%) of patients achieved a total PO diet post-operatively, with median time to achievement of 3.2 months. Multivariate analysis identified that lack of concurrent glossectomy (SHR 1.72 [1.09-2.70], p = 0.02), N0/1 disease (SHR 1.92 [1.16-3.13], p = 0.011), avoidance of post-operative fistula formation (SHR 1.96 [1.22-3.23], p = 0.005), pre-operative G-tube independence (SHR 3.33 [1.69-6.25], p < 0.001), and successful dental rehabilitation (SHR 2.08 [1.43-3.03], p < 0.001) are independently associated with total oral diet achievement. CONCLUSIONS: Bony resections not requiring glossectomy, limited nodal disease burden, pre-operative gastrostomy-independence, avoidance of post-operative fistula, and dental rehabilitation are independently associated with achievement of total oral diet following OMFTT reconstruction of the oral cavity. Counseling patients on associated risk factors is important in guiding post-treatment expectations. Minimization of post-operative fistula, and maximization of dental rehabilitation may significantly improve total oral diet achievement in this patient population.

Prognostic factors associated with achieving total oral diet after glossectomy with microvascular free tissue transfer reconstruction.

OBJECTIVE: Primary surgery followed by adjuvant therapy is the current standard of care in the multidisciplinary management of squamous cell carcinoma (SCC) of the oral tongue. Additionally, salvage glossectomy is used to treat recurrent base of tongue SCC. Microvascular free tissue transfer reconstruction (MVFTT) is utilized to maximize functional outcomes such as swallowing. We sought to identify prognostic factors related to achievement of a total oral diet in patients that underwent glossectomy with MVFTT. METHODS: Retrospective review at a tertiary care center from 2010 to 2015. RESULTS: 200 patients (69% male, mean age 60 years) met inclusion criteria. Extent of glossectomy was categorized as partial or hemiglossectomy (39%), tongue base resection with or without hemi-oral glossectomy (23%), composite resection with mandibulectomy (18%), and subtotal or total glossectomy (21%). Flap success rate was 96%. Median follow-up time was 14  months. A total oral diet was achieved by 49% of patients with median time to achievement of 31  days (IQR 9-209). Multivariate analysis identified body mass index  < 25 kg/m2, prior radiation therapy, adjuvant chemoradiation, and resection requiring subtotal or total glossectomy or concurrent mandibulectomy as independent risk factors for worse total oral diet achievement. CONCLUSION: Swallowing dysfunction represents a significant morbidity following glossectomy in the treatment of SCC. High BMI, smaller resection fields, and absence of prior radiation therapy or adjuvant chemoradiotherapy correlated with improved likelihood of obtaining a total oral diet. Patients should be appropriately counseled of this risk with emphasis placed on aggressive swallow rehabilitation in the post- treatment setting.

Swallowing function after chemoradiation for advanced stage oropharyngeal cancer.

OBJECTIVE: Advanced-stage oropharyngeal cancer may be treated either surgically or nonsurgically. We reported previously functional outcomes after surgical resection with free-tissue transfer. In the present study, we evaluated swallowing function after combined chemoradiation for oropharyngeal cancer. STUDY DESIGN AND SETTING: Retrospective review of 30 patients treated at a tertiary academic center for Stage III/IV oropharyngeal cancer with sequential or concurrent chemoradiation from 1994 to 2003. RESULTS: Inclusion criteria were met by 27 of 30 (90%) patients. Most patients had base of tongue lesions (67%) and Stage IV disease (93%). Gastrostomy was carried out in 22 (82%) patients either before or during treatment. Three months after chemoradiation, 33% (9/27) were consuming all nutrition orally, 22% (6 of 27) were NPO, and 45% (12 of 27) had some oral intake but still required tube feeds. One year after treatment, 53% (10 of 19) had an exclusively oral diet whereas 47% still required tube feeds including 1 patient (5%) who was NPO. In patients without recurrence and follow-up length >1 year, 69% (9 of 13) were consuming all nutrition orally whereas 31% still required gastrostomy tube (G-tube) support. A higher rate of G-tube dependence was observed in patients treated for base of tongue lesions vs tonsil lesions (67% vs 25%, P = 0.049, chi(2) analysis). CONCLUSIONS: At this institution, the short-term (3-4 months) rate of G-tube dependence was similar after surgical and non-surgical treatment of oropharyngeal cancer. One year after chemoradiation, 31% of patients without recurrence still required tube feeds. SIGNIFICANCE: These results suggest that organ-preservation protocols do not reduce the prevalence of chronic dysphagia and G-tube dependence after management of oropharyngeal cancer. EBM RATING: C-4.

Intraoperative goal-directed hemodynamic management in free tissue transfer for head and neck cancer.

BACKGROUND: The purpose of this study was to determine the effect of algorithmic physiologic management on patients undergoing head and neck free tissue transfer and reconstruction. METHODS: Ninety-four adult patients were randomized to treatment and control groups. The blood pressure of the control group was managed consistent with contemporary standards. The treatment group was managed using an algorithm based on blood pressure and calculated physiologic values derived from arterial waveform analysis. Primary outcome was intensive care unit (ICU) length of stay. RESULTS: ICU length of stay was decreased in the treatment group (33.7 vs 58.3 hours; p = .026). The complication rate was not increased in the treatment group. CONCLUSION: The goal-directed hemodynamic management algorithm decreased the ICU length of stay. Judicious use of vasoactive drugs and goal-directed fluid administration has a role in improving perioperative outcomes for patients undergoing head and neck free tissue transfer. © 2016 Wiley Periodicals, Inc.

Short-term functional donor site morbidity after radial forearm fasciocutaneous free flap harvest.

OBJECTIVES/HYPOTHESIS: The existing literature on postoperative donor extremity function describes a spectrum of morbidity in the long term (>3 mo after surgery). However, the consensus is that there is minimal to no impact of flap harvest on patients' activities of daily living. No previous reports have examined functional donor site morbidity in the early postoperative period; such may affect patients' overall perioperative progress, especially with respect to donor extremity dominance. The authors' objective was to quantify functional morbidity of the donor site in radial forearm fasciocutaneous free flaps during the early postoperative period. STUDY DESIGN: Retrospective case series review. METHODS: Patient data were obtained from hospital records of 12 consecutive patients who underwent head and neck reconstruction with radial forearm fasciocutaneous free tissue transfer over a 6-month period at a tertiary academic medical center. Functional results of each patient's donor extremity obtained preoperatively and at 5 to 8 days after surgery were determined by quantifying forearm supination and pronation, wrist flexion and extension, and sharp and dull hand sensations in radial, median, and ulnar nerve distributions. RESULTS: Mean patient age was 57 years (age range, 42-71 y). The nondominant extremity was the donor site in 9 of 12 patients. Using the paired two-tailed t test, statistically significant differences were demonstrated in preoperative versus postoperative forearm supination (P <.032), pronation (P <.006), wrist flexion (P <.000), and wrist extension (P <.000). Three of 12 patients demonstrated diminished sharp sensation in the "anatomical snuffbox" distribution. CONCLUSION: The authors describe statistically significant functional forearm and wrist range-of-motion morbidity associated with the harvest of a radial forearm fasciocutaneous free flap in the early postoperative period.

Swallowing function and tracheotomy dependence after combined-modality treatment including free tissue transfer for advanced-stage oropharyngeal cancer.

OBJECTIVES/HYPOTHESIS: There are many treatments available for advanced oropharyngeal cancer. Organ-sparing protocols reserve surgery for salvage and are thought to provide adequate rehabilitation. Surgical resection with free tissue transfer may also provide adequate functional rehabilitation. The objective was to describe swallowing status and time to decannulation in a series of patients treated with combined-modality therapy that included free flap reconstruction. STUDY DESIGN: Retrospective chart review. METHODS: Patient data were obtained from medical records of 20 patients with stage III or IV oropharyngeal carcinoma, who were consecutively treated with surgical tumor extirpation, free flap reconstruction, and postoperative irradiation at a tertiary academic center from 1985 to 2002. The following variables were identified: patient and tumor characteristics, free flap type, irradiation data, and airway and swallowing status before and after treatment. RESULTS: One patient underwent total laryngopharyngectomy, and the remaining 19 patients underwent tracheotomy at the time of definitive surgery. Free flap reconstructions included 1 ulnar and 15 radial forearm fasciocutaneous flaps and 4 fibula osteocutaneous flaps. Postoperatively, all 19 tracheotomized patients had successful decannulation. Average time to decannulation was 15 days (range, 3-42 d). After surgery and before irradiation, 13 patients initiated oral intake, on average, at 19.5 days (range, 7-28 d); 6 patients required no additional supplementation. By 4 months after surgery, having completed radiation therapy, 10 patients were consuming all nutrition orally; the other 10 patients still required tube-feed supplementation, although 6 of these patients were also eating by mouth. CONCLUSION: Combined-modality treatment that includes free flap reconstruction for advanced-stage oropharyngeal cancer may provide reasonable functional rehabilitation with respect to postoperative airway and swallowing.

Massive flap donor sites and the role of negative pressure wound therapy.

OBJECTIVE: Report our experience with negative pressure wound therapy (NPWT) applied to massive scapular and latissimus free flap donor sites, in the setting of microvascular reconstruction for extensive head and neck defects. STUDY DESIGN: Retrospective case series with chart review. SETTING: Tertiary academic referral center. SUBJECTS AND METHODS: Retrospective review was conducted of all patients who underwent scapular or latissimus free tissue transfer by the senior author for head and neck reconstruction, over a 5-year period (2006-2011). In addition to NPWT details, comprehensive patient data were abstracted and compiled, including demographics, operative details, hospital stay, postoperative follow-up, and donor site complications. RESULTS: Ninety-four patients underwent reconstruction of extensive postablative head and neck defects using either a scapular or latissimus free flap. Mean harvested flap skin paddle size was 140 cm(2). All donor sites were closed primarily. Fifty-two patients (55%) had NPWT applied over closed donor site incisions postoperatively. The other 42 patients (45%) received only conventional incision care. Major donor site complications occurred in 12% (n = 5) of the patients who did not undergo NPWT, as compared with a 6% (n = 3) complication rate among patients in the NPWT-treated group. CONCLUSION: This is the first study to examine NPWT in the postoperative treatment of closed high-tension wounds following scapular or latissimus dorsi harvest for reconstruction of extensive head and neck defects. Our results suggest that NPWT is a safe technique in the management of massive scapular and latissimus free flap harvest sites that may decrease associated major donor wound complications.

Microvascular free-tissue transfer for head and neck reconstruction in Jehovah's Witness patients.

BACKGROUND: Jehovah's Witnesses' religious convictions disallow blood transfusion. Major surgery in these patients is therefore problematic. The objective of this study is to describe our experience with microvascular reconstruction of complex head and neck defects in Jehovah's Witness patients. METHODS: This was a retrospective review of all Jehovah's Witnesses' patients undergoing head and neck free-flap reconstruction at a tertiary academic referral center from 1997 to 2006. RESULTS: Five Jehovah's Witnesses patients underwent a total of 7 free-flap reconstructions (6 radial, 1 rectus). Four flaps were immediate: 1 osteocutaneous radial forearm, 2 fasciocutaneous radial forearm, and 1 rectus abdominus myocutaneous. One fasciocutaneous radial forearm flap was staged. Two patients were planned secondary reconstructions, both facsciocutaneous radial forearm. Iron supplements and/or erythropoietin were administered perioperatively in 6 of the 7 microvascular reconstructions. Selective external carotid embolization was performed preoperatively in 1 patient. Hematocrit levels were 36% to 46% preoperatively and 30% to 41% postoperatively. Immediate postoperative hematocrit decline was 5.2% (3.0% to 6.0%). No transfusions or blood products were administered. CONCLUSIONS: Our case series supports the feasibility of head and neck free-flap reconstruction in these challenging patients.

Repair of the unilateral cleft lip/nose deformity.

Successful surgical repair of the unilateral cleft lip and nose deformity, defined as normal orbicularis oris function and near-perfect symmetry of the repaired lip and nose, demands that the surgeon possess complete understanding of the embryology and anatomy of the midfacial defects. The surgical approach to repair of the unilateral cleft lip/nose should place great emphasis on achieving symmetry, not only with the lip segments but also perhaps even more importantly with the nasal tip. The reconstruction should recreate an intact fully functional orbicularis oris muscle across the cleft and camouflage the scar optimally. We have found that modification of the Millard rotation-advancement flap technique, with particular attention to the primary nasal repair, provides the best outcomes. In patients who have undergone primary repair of the lip and/or nose deformity, secondary rhinoplasty is generally required, regardless of the technique used at the primary repair. The degree of nasal deformity, however, is less severe following primary repair of the asymmetric nasal tip. We have found that the sliding flap cheliorhinoplasty, Wang's modification of the Vissarionov technique, provides excellent results for most secondary cleft rhinoplasties.
