Predicting length of stay in head and neck patients who undergo free flap reconstruction

Submandibular Gland Flap Reconstruction for Oropharyngeal Defects After Transoral Robotic Surgery (TORS)

BACKGROUND

To describe utilization and outcomes of submandibular gland flap (SGF) reconstruction after transoral robotic surgery (TORS) for oropharyngeal squamous cell carcinoma (OPSCC).

METHODS

A multi-institutional retrospective case series of patients who underwent TORS for OPSCC followed by SGF reconstruction with harvest via transcervical approach from 1/1/2016 to 4/1/2023.

RESULTS

In total, 14 patients underwent SGF reconstruction after TORS for OPSCC. All patients had HPV-positive disease, predominantly in early local (N = 10 with pT1/pT2 disease, 71%) and regional stages (N = 11 with pN0/pN1 disease, 79%). Most patients received adjuvant radiation treatment (N = 9, 64%). Median hospital LOS after surgery was 4 days (IQR 2 days) with median functional oral intake scale (FOIS) score of 5 (IQR 0.8) at 1-3 weeks after surgery.

CONCLUSIONS

SGF reconstruction is a useful technique for closure of appropriately selected TORS defects requiring reconstruction beyond healing by secondary intention and mobilization of adjacent tissue but not large enough to warrant free flap reconstruction.

Safety of An Enhanced Recovery After Surgery Protocol After Head and Neck Free Tissue Transfer

OBJECTIVES

Implementing enhanced recovery after surgery (ERAS) protocols and decreasing length of stay (LOS) have become a priority for major surgeries, including microvascular free tissue transfer (MVFTT) reconstruction of the head and neck. We describe an ERAS protocol with the goal to further reduce length of stay beyond national medians.

METHODS

Retrospective chart review between August 2016 and February 2023, including all patients who underwent MVFTT after oral cavity, skull base, salivary gland, and cutaneous ablative surgery. An ERAS protocol was implemented in March 2020.

RESULTS

A total of 383 patients were included. Approximately 59.8% underwent oral cavity MVFTT, 34.5% cutaneous and lateral skull base, and 5.8% maxillary and anterior skull base. A total of 209 (54.7%) patients had surgery prior to implementation of the ERAS protocol and 174 (45.3%) after. Median LOS decreased from 9 days (interquartile interval [IQR] 8-11) to 6 (IQR 5-7.5, p < 0.0001) following oral cavity MVFTT. For cutaneous and lateral skull base reconstruction, median LOS decreased from 6 days (IQR 5-8) to 3 (IQR 3-7, p < 0.0001). For anterior skull base and sinonasal MVFTT, median LOS decreased from 8 (IQR 7-9) to 5 days (IQR 4.5-7, p = 0.0005). Rate of discharge to skilled nursing or subacute rehabilitation facilities decreased (24% before ERAS, 9.2% after, p < 0.0001). Thirty-day readmission rate was similar before and after implementation (10.5% vs. 10.3, p = 0.954). Discharge to facility was associated with readmission (OR 2.34, 95% CI 1.12-4.89, p = 0.024).

CONCLUSION AND RELEVANCE

Implementation of the ERAS protocol was associated with decreased LOS. There was no increase in rate of readmission.

NovoSorb® biodegradable temporising matrix (BTM) in the reconstruction of cutaneous malignancies in a major cancer centre: a case series

BACKGROUND

Non-graftable or composite defect reconstruction represents a major challenge to the reconstructive surgeon, with many wounds requiring local flap or free microvascular tissue transfer approaches. The recent advent of synthetic skin substitutes such as Biodegradable Temporizing Matrix (BTM) have revolutionized the management of complex defects including those caused by burns, trauma and infection, with low-morbidity and low-complexity surgery. However, limited data exist supporting their use in cancer reconstruction in Australia.

METHODS

We performed a prospective cohort study of patients undergoing cancer resection and reconstruction with BTM between February 2021 and February 2023 in our institution. Reported outcomes included matrix integration, infection, and return to theatre.

RESULTS

Twelve patients underwent reconstruction of primary or secondary defects following cancer resection during this period. Eight patients were male, four female, mean age at surgery was 70 years. Pathology resected included squamous cell carcinoma (SCC) and melanoma of the head and neck, sarcoma resection of the lower limb, and osteoradionecrosis (ORN) of the scalp. T-stage of primary tumours ranged from T2 to T4 and one in-transit metastasis of melanoma. Four patients were treated with radiotherapy, two of whom received postoperative radiotherapy (PORT) and two who received neoadjuvant radiotherapy, three additional patients had an intervention to a previously irradiated wound bed for recurrence or ORN. Overall matrix integration was 83% (10/12), with a 50% integration rate (2/4) observed in the post-radiotherapy group, requiring return to theatre for alternative reconstructive approaches.

CONCLUSION

We report our experience with a synthetic dermal matrix (BTM) in cancer reconstruction, the largest cohort of this type in the Australian literature. BTM represents an exciting reconstructive tool for the cancer reconstructive surgeon, with a high rate of success and low morbidity.

Factors Predicting Discharge Disposition Following Head and Neck Free Flap Reconstruction

OBJECTIVES

Patients undergoing head and neck free flap reconstruction (HNFFR) may have significant change to their baseline functional status requiring inpatient rehabilitation (IPR) after discharge. We sought to identify patient/procedure characteristics predictive of discharge destination.

METHODS

Patients undergoing elective HNFFR between July 2017 and July 2022 were reviewed for discharge destination. Those discharged to IPR versus home were compared across patient/procedure characteristics and physical/occupational therapy metrics. Significance was assessed via bivariate and multivariable analyses.

RESULTS

Of the 531 patients, 102 (19.2%) required IPR postoperatively. Patients discharged to IPR versus home were significantly older (70.1 [11.6] vs. 64.1 [13.1] years; p < 0.001) and more likely to lack family assistance (26.5% vs. 8.6%; p < 0.001), require baseline assistance for activities of daily living (ADLs) (31.4% vs. 9.8%; p < 0.001), have baseline cognitive dysfunction (15.7% vs. 6.1%; p = 0.001), were more likely to have neoplasm as the surgical indication for HNFFR (89.2% vs. 80.0%; p = 0.033) and more likely to have a tracheostomy postop (62.7% vs. 51.7%), and had a significantly longer length of stay (11.2 [8.0] vs. 6.8 [8.3] days; p < 0.001). There was no significant difference in gender, donor site, use of tube feeds, and use of assistive devices between the two groups. Following logistic regression, the strongest predictors of discharge to IPR include lack of family assistance (OR = 3.8; p < 0.001) and baseline assistance for ADLs (OR = 4.0, p < 0.001).

CONCLUSION

Certain patient factors predict the need for discharge to rehab after HNFFR. Perioperative identification of these factors may facilitate patient counseling and discharge planning with potential to reduce hospital length of stay and further optimize patient care.

Development and validation of a novel nomogram model for identifying risk of prolonged length of stay among patients receiving free vascularized flap reconstruction of head and neck cancer

BACKGROUND

The aim of the present study was to build and internally validate a nomogram model for predicting prolonged length of stay (PLOS) among patients receiving free vascularized flap reconstruction of head and neck cancer (HNC).

METHODS

A retrospective clinical study was performed at a single center, examining patients receiving free vascularized flap reconstruction of HNC from January 2011 to January 2019. The variables were obtained from the electronic information system. The primary outcome measure was PLOS. Univariate and multivariate analyses were used to find risk factors for predicting PLOS. A model was then built according to multivariate results. Internal validation was implemented via 1000 bootstrap samples.

RESULTS

The study included 1047 patients, and the median length of stay (LOS) was 13.00 (11.00, 16.00) days. Multivariate analysis showed that flap types ((radial forearm free flap (odds ratio [OR] = 2.238; 95% CI, 1.403-3.569; P = 0.001), free fibula flap (OR = 3.319; 95% CI, 2.019-4.882; P < 0.001)), duration of surgery (OR = 1.002; 95% CI, 1.001-1.003; P = 0.004), postoperative complications (OR = 0.205; 95% CI, 0.129-0.325; P = P < 0.001) and unplanned reoperation (OR = 0.303; 95% CI, 0.140-0.653; P = 0.002) were associated with PLOS. In addition to these variables, blood transfusion was comprised in the model. The AUC of the model was 0.78 (95% CI, 0.711-0.849) and 0.725 (95% CI, 0.605-0.845) in the primary and internal validation cohorts, respectively. The DCA revealed the clinical utility of the current model when making intervention decisions within the PLOS possibility threshold range of 0.2-0.8.

CONCLUSIONS

Our study developed a nomogram that exhibits a commendable level of accuracy, thereby aiding clinicians in assessing the risk of PLOS among patients receiving free vascularized flap reconstruction for HNC.

Early ambulation after fibular free flap surgery is associated with reduced length of stay, increased mobility independence, and discharge to home

BACKGROUND

Fibula free flaps (FFF) are one of the most common bony flaps utilized. This paper describes a quality improvement project aimed at increasing early ambulation.

METHODS

A review of FFF patients at an academic hospital was completed (2014-2023). In 2018, an institutional change to encourage early ambulation without placement of a boot was made. Changes in hospital disposition and physical therapy outcomes were evaluated.

RESULTS

A total of 168 patients underwent FFF reconstruction. There was a statistically significant lower length of stay in Group 2 (early ambulation, no boot) (8.1 vs. 9.4; p = 0.04). A higher rate of discharge to a skilled nursing facility was noted in Group 1 (delayed ambulation with boot) (21.3% vs. 11.9%; p = 0.009). A higher proportion of patients in Group 2 demonstrated independence during bed mobility, transfers, and gait (p < 0.05).

CONCLUSIONS

Early ambulation without boot placement after FFF is associated with decreased length of hospital stay, improved disposition to home and physical therapy outcomes.

Minimally Invasive Approach to Access Vessels for Microvascular Anastomosis in Head and Neck Reconstruction

OBJECTIVES

To describe our technique, review indications, and evaluate the outcomes of the minimal access approach for recipient vessel identification in microvascular tissue transfer.

METHODS

Retrospective chart review of all patients who underwent microvascular reconstruction using the minimal access technique between 2015 and 2021.

RESULTS

We report 236 cases, comprising 214 patients with a mean age of 60.2 years (3-88). The most common primary defect sites were the mandible (22.6%), cranium (14%), maxilla (13.2%), skull base (12.8%), and nose/nasal cavity (10.6%). Indications for free flap reconstruction included head and neck cancer extirpation (32.2%), osteoradionecrosis (29.7%), acquired deformity (14.0%), chronic wound (11.9%) and oral motor dysfunction (7.2%). Free flap donor sites used were the anterolateral thigh (84.3%), fibula (7.2%), and radial forearm (6.4%). Vessels utilized include superficial temporal (49.8%), facial (38.3%), angular (11.1%), and transverse cervical (0.4%). The overall complication rate was 14% (n = 33), with surgical complications at the recipient site accounting for 67.6% (n = 25). Flap failure occurred in 3.4% of procedures. Prior head and neck surgery and free flaps were associated with an increased risk of major recipient site complications (n = 20, p = 0.0257 and n = 14, p = 0.0117, respectively).

CONCLUSION

Minimal access techniques allow consistent recipient vessel identification for microvascular-free tissue transfer. These approaches may be utilized in reconstructing a broad range of head and neck defects, are low morbidity, and contribute to an overall shorter length of stay.

Outcomes of Head and Neck Free Tissue Transfer in Renal Failure Patients

OBJECTIVE

To assess if there is increased risk of free flap failure in renal failure patients undergoing head and neck reconstruction. We seek to primarily assess free flap outcomes based on stages of chronic kidney disease (CKD) and secondarily determine increased risk for postoperative complications.

METHODS

Retrospective chart review was performed at five tertiary care centers. Patients were identified that had undergone microvascular free flap reconstruction of the head and neck with diagnosis of renal failure, classified as Stage 3 CKD or higher. Demographic data was collected. Outcomes in the postoperative period were examined.

RESULTS

Seventy-three patients met inclusion criteria. The average patient age was 69 years with a male predominance (n = 48). The majority of patients had CKD Stage 3 (n = 52). Overall flap failure rate was 12.33% (n = 9, CKD stage 3 = 7.69%, CKD stage 4 = 30%, CKD stage 5 = 18%). There was an increased risk of flap failure on multivariate analysis for CKD stage 4/5 patients when compared to CKD 3 patients (p = 0.0095). When compared to matched controls, there was an increased risk of flap failure in CKD patients (p = 0.01) as well as an increased risk of overall complications (p < 0.0001).

CONCLUSIONS

Patients with CKD undergoing head and neck reconstruction are at a higher risk of flap failure and overall complications. When comparing CKD stages there may be increased risk of flap failure in later stages of CKD compared to CKD 3. Appropriate patient counseling is recommended pre-operatively in this patient population with consideration for regional flaps in the appropriate patient.

Mathematical approach improves predictability of length of hospitalisation due to oral squamous cell carcinoma: a retrospective investigation of 153 patients

Oral squamous cell carcinoma (OSCC), a common cancer of the head and neck, is a major public health problem. The length of stay in hospital (LOS) of patients with OSCC, which can range from a few days to several months, has implications for the patient's recovery. The aim of the study was to identify and evaluate risk factors that have an impact on the prolongation of inpatient hospital stay. A four-year retrospective study reviewed hospital records of 153 inpatients with OSCC. A statistical model for discrete time-to-event data, with the LOS in hospital measured in days for which the event of interest was discharge from hospital, was applied. The model utilises a tree-building algorithm to identify relevant risk factors for a prolonged LOS. Age, type of flap, and occurrence of complications turned out to be relevant variables. Before, and on day 12, the LOS was mainly dependent on flap type and age, whereas after day 12 it was influenced by the presence of early complications. Predicting the likelihood of discharge can improve the management and resource utilisation of the healthcare system among inpatients.

The Controlling Nutritional Status (CONUT) Score for Prediction of Microvascular Flap Complications in Reconstructive Surgery

Microvascular flap surgery is a widely acknowledged procedure for significant defect reconstruction. Multiple flap complication risk factors have been identified, yet there are limited data on laboratory biomarkers for the prediction of flap loss. The controlling nutritional status (CONUT) score has demonstrated good postoperative outcome assessment ability in diverse surgical populations. We aim to assess the predictive value of the CONUT score for complications in microvascular flap surgery. This prospective cohort study includes 72 adult patients undergoing elective microvascular flap surgery. Preoperative blood draws for analysis of full blood count, total plasma cholesterol, and albumin concentrations were collected on the day of surgery before crystalloid infusion. Postoperative data on flap complications and duration of hospitalization were obtained. The overall complication rate was 15.2%. True flap loss with vascular compromise occurred in 5.6%. No differences in flap complications were found between different areas of reconstruction, anatomical flap types, or indications for surgery. Obesity was more common in patients with flap complications (p = 0.01). The CONUT score had an AUC of 0.813 (0.659-0.967, p = 0.012) for predicting complications other than true flap loss due to vascular compromise. A CONUT score > 2 was indicated as optimal during cut-off analysis (p = 0.022). Patients with flap complications had a longer duration of hospitalization (13.55, 10.99-16.11 vs. 25.38, 14.82-35.93; p = 0.004). Our findings indicate that the CONUT score has considerable predictive value in microvascular flap surgery.

Restarting Therapeutic Antibiotics Following Postoperative Prophylaxis in Head and Neck Microvascular Free Tissue Transfer

OBJECTIVE

To determine factors associated with restarting therapeutic antibiotics within 30 days of head and neck microvascular free tissue transfer (HN-MFTT).

STUDY DESIGN

Retrospective study of consecutive HN-MFTTs performed from January 2015 to July 2020.

SETTING

Tertiary academic medical center.

METHODS

Thirty-day postoperative antibiotic use and post-HN-MFTT surgical and medical complications were assessed. Univariable analyses and multivariable logistic regression were used to evaluate risk factors associated with restarting antibiotics.

RESULTS

overall 482 patients with 501 HN-MFTTs were stratified by duration of prophylaxis: ≤24 hours (n = 136, 27.1%), 25-72 hours (n = 54, 10.8%), and >72 hours (n = 311, 62.1%). Antibiotics were restarted in 199 patients (209 procedures, 42%). The most common indications for antibiotic reinitiation were flap recipient site infection (n = 59, 28%); hospital-acquired pneumonia (n = 44, 21%); and wound dehiscence, fluctuance, or change in quality of drain output (n = 44, 21%). Shorter antibiotic prophylaxis (≤24 hours) (odds ratio [OR], 1.95; 95% CI, 1.2-3.0; P = .003), osteocutaneous flaps (OR, 2.15; 95% CI, 1.3-3.4; P = .001), and prior immunotherapy/chemotherapy (OR, 2.29; 95% CI, 1.2-4.3; P = .01) were associated with reinitiation of antibiotics for surgical infections. Restarting antimicrobials for nosocomial infections was associated with aerodigestive defects (OR, 2.45; 95% CI, 1.1-5.2; P = .019), cardiovascular disease (OR, 3.00; 95% CI, 1.5-5.9; P = .001), and medical comorbidities approximated by American Society of Anesthesiologists class 3 or 4 (OR, 2.83; 95% CI, 1.5-5.4; P = .002).

CONCLUSION

Aerodigestive reconstruction, 24-hour postoperative antimicrobial prophylaxis, American Society of Anesthesiologists class 3 and 4, prior chemotherapy/immunotherapy, cardiovascular disease, and osteocutaneous flaps are associated with reinitiation of antibiotics within 30 days of HN-MFTT.

The comprehensive on-demand 3D bio-printing for composite reconstruction of mandibular defects

Background

The mandible is a functional bio-organ that supports facial structures and helps mastication and speaking. Large mandible defects, generally greater than 6-cm segment loss, may require composite tissue reconstruction such as osteocutaneous-vascularized free flap which has a limitation of additional surgery and a functional morbidity at the donor site. A 3D bio-printing technology is recently developed to overcome the limitation in the composite reconstruction of the mandible using osteocutaneous-vascularized free flap.

Review

Scaffold, cells, and bioactive molecules are essential for a 3D bio-printing. For mandibular reconstruction, materials in a 3D bio-printing require mechanical strength, resilience, and biocompatibility. Recently, an integrated tissue and organ printing system with multiple cartridges are designed and it is capable of printing polymers to reinforce the printed structure, such as hydrogel.

Conclusion

For successful composite tissue reconstruction of the mandible, biologic considerations and components should be presented with a comprehensive on-demand online platform model of customized approaches.

Harmonic scalpels compared with electrocautery in reconstructive flap harvesting: A meta-analysis

BACKGROUND

Numerous studies have compared electrical devices used for flap surgery, but the results are inconsistent. This research was performed to evaluate the efficacy of two different types of electric devices: electrocautery and ultrasonic shears.

METHODS

The PubMed, Embase, and Scopus databases were searched systematically. A total of 505 cases were included in this study, including 209 electrocautery and 296 harmonic scalpel cases. The following information was retrieved from the included studies: the first author of the article, publication year, flap type, flap harvest time, drain volume, bleeding volume and postoperative complications. Hematoma, infection, flap necrosis and wound dehiscence were considered postoperative complications. The Q statistic for heterogeneity and the I² index were calculated. If I²  < 50%, we used a fixed-effects model; if I²  > 50%, we employed a random-effects model in our meta-analysis.

RESULTS

A total of eight studies which met the inclusion criteria were included and reviewed systematically for a meta-analysis. The harmonic scalpel yielded a statistically significantly more favorable flap harvest time and drain volume than did electrocautery. The Harmonic scalpel led to a shorter flap harvest time by 26.29 min (95% CI = -39.38 to -13.2; p < .00001) and smaller drain volume by 58.76 ml (95% CI = -105.27 to -12.25; p = .01) on average. However, there were no significant differences in the bleeding volume or incidence rates of infection, flap necrosis and wound dehiscence.

CONCLUSION

The Harmonic scalpel method yields better outcomes in terms of the flap harvest time and drain volume than does the conventional electrocautery method. Therefore, the Harmonic scalpel is a better option for cauterization and dissection in flap surgery.

Impact of Preoperative Risk Factors on Inpatient Stay and Facility Discharge After Free Flap Reconstruction

OBJECTIVE

To determine the preoperative risk factors most predictive of prolonged length of stay (LOS) or admission to a skilled nursing facility (SNF) or inpatient rehabilitation center (IPR) after free flap reconstruction of the head and neck.

STUDY DESIGN

Retrospective cohort study.

SETTING

Tertiary academic medical center.

METHODS

Retrospective review of 1008 patients who underwent tumor resection and free flap reconstruction of the head and neck at a tertiary referral center from 2002 to 2019.

RESULTS

Of 1008 patients (65.7% male; mean age of 61.4 years, SD 14.0 years), 161 (15.6%) were discharged to SNF/IPR, and the median LOS was 7 days. In multiple linear regression analysis, Charlson Comorbidity Index (CCI; P < .001), American Society of Anesthesiologists (ASA) classification (P = .021), female gender (P = .023), and inability to tolerate oral diet preoperatively (P = .006) were statistically significantly related to increased LOS, whereas age, body mass index (BMI), modified frailty index (MFI), a history of prior radiation or chemotherapy, and home oxygen use were not. Multiple logistic regression analysis demonstrated that CCI (odds ratio [OR] = 1.119, confidence interval [CI] 1.023-1.223), age (OR = 1.082, CI 1.056-1.108), and BMI <19.0 (OR = 2.141, CI 1.159-3.807) were the only variables statistically significantly related to posthospital placement in an SNF or IPR.

CONCLUSION

Common tools for assessing frailty and need for additional care may be inadequate in a head and neck reconstructive population. CCI appears to be the best of the aggregate metrics assessed, with significant relationships to both LOS and placement in SNF/IPR.

Does Supplemental Regional Anesthesia Decrease Length of Stay and Opioid Use for Patients Undergoing Head and Neck Microvascular Reconstruction?

PURPOSE

The purpose of this study was to compare length of hospital stay and opioid usage among head and neck surgery (HNS) patients treated with and without regional anesthesia for microvascular free-flap donor sites.

METHODS

The authors performed a retrospective cohort study for HNS patients undergoing microvascular free-flap reconstruction. The control group received no regional anesthesia. The experimental group had a regional anesthesia nerve block performed immediately before surgery. The primary outcome variable was length of stay, and the secondary outcome variable was total morphine milliequivalents. The data were analyzed using Student t tests, analysis of variance, Mann-Whitney U test, Kruskal-Wallis test, χ² test, and multiple linear regression.

RESULTS

The study sample was composed of 148 patients with a mean age of 58.1 years. The mean length of stay for the control group was 6.74 ± 1.57 days, compared with the experimental group at 5.84 ± 1.01 days (P < .0001). The mean morphine milliequivalent was 256.5 ± 164.6 mg for the control group and 208.9 ± 164.8 mg for the experimental group (P = .56). Importantly, the demographics, pathology spectrum, flap selection, duration of procedure, and complication rate were similar in both groups.

CONCLUSIONS

This study demonstrates that for HNS patients undergoing microvascular reconstruction, regional nerve block at the donor site is associated with significantly shorter hospital stays. Although there was a trend toward decreased opioid usage in the regional anesthesia group, these results did not reach statistical significance. Consideration should be given to incorporate regional anesthesia techniques into early recovery after surgery protocols for centers performing high-volume head and neck microvascular reconstruction.
