Head and neck reconstruction in the elderly patient: a safe procedure?

Aesthetic Rehabilitation Medicine: Enhancing Wellbeing beyond Functional Recovery

Although rehabilitation medicine emphasizes a holistic health approach, there is still a large gap of knowledge about potential interventions aimed at improving overall wellbeing through cosmetic interventions. Therefore, this narrative review investigates the role of different rehabilitative techniques in enhancing aesthetics, quality of life, and psychosocial wellbeing for patients with disabilities. The study follows the SANRA framework quality criteria for a narrative review. Literature searches across PubMed/Medline, Web of Science, and Scopus identified articles focusing on rehabilitation strategies within the aesthetic rehabilitation domain. The review identified evidence supporting injection procedures, such as Botulinum Toxin, Platelet-Rich Plasma, Hyaluronic Acid, Ozone, and Carboxytherapy, and assessing their applications in several disabling disorders. Additionally, physical therapies like Extracorporeal Shock Wave Therapy, Laser Therapy, Microcurrent Therapy, Tecar Therapy, and physical exercises were explored for their impact on cutaneous microcirculation, cellulite treatment, wound healing, and scar appearance improvement. Lastly, the manuscript underlines the role of manual therapy techniques in addressing both physical discomfort and aesthetic concerns, discussing their effectiveness in adipose tissue therapy, scar tissue mobilization, and regional fat thickness reduction. Taken together, this review emphasizes the role of a multidisciplinary approach, aiming to provide valuable insights into potential benefits for both functional and aesthetic outcomes.

Safe Free Tissue Transfer in Patients Older than 90 Years

Objective This study aimed to evaluate the safety of microvascular free tissue transfer in the elderly patient population.

Methods We performed a 20-year retrospective review at a tertiary care private practice of patients of ≥ 90 years of age who underwent microvascular free tissue transfer and had at least 6 months of follow-up. Similarly, we reviewed patients aged 70 to 89 years who underwent free tissue transfer between 2018 and 2020 as a control group. Records were examined for type of flap, defect site, pathology, and occurrence of complications.

Results Overall 77 patients of 90 years or older met the inclusion criteria and 77 sequential patients aged 70 to 89 years were identified to serve as a control group. The overall complication rate among patients of ≥ 90 years of age was 18%, with flap-related complications in 4% (two partial flap loss and one total loss). The mortality rate was 1.3%. All patients of ≥ 90 years of age undergoing osteocutaneous reconstruction for osteoradionecrosis experienced complications, but only one was a flap complication (partial loss). Among patients aged 70 to 89 years, the overall complication rate was also 18%, with flap-related complications in 4% (two complete flap failures and one partial loss). The mortality rate in the control group was 2.6%.

Conclusion Soft tissue free flaps are a safe option in the elderly patient population and should be offered to patients who are medically optimized prior to surgery, regardless of age. Osteocutaneous reconstruction for osteoradionecrosis must be undertaken with caution. This study reflects level of evidence 4.

The Utility of Comorbidity Indices in Assessing Head and Neck Surgery Outcomes: A Systematic Review

OBJECTIVE

To evaluate the utility of comorbidity index (CI) scores in predicting outcomes in head and neck surgery (HNS). The CIs evaluated were the Charlson Comorbidity Index (CCI), Elixhauser Comorbidity Index (ECI), Kaplan-Feinstein Index (KFI), American Society of Anesthesiologists Physical Status (ASA-PS), Adult Comorbidity Evaluation-27 (ACE-27), National Cancer Institute Comorbidity Index (NCI-CI), and the Washington University Head and Neck Comorbidity Index (WUHNCI).

METHODS

We report a systematic review according to the 2009 Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Electronic databases (PubMed, Cochrane, and Embase) and manual search of bibliographies identified manuscripts addressing how CI scores related to HNS outcomes.

RESULTS

A total of 116 studies associated CI scores with HNS outcomes. CIs were represented in the literature as follows: ASA-PS (70/116), CCI (39/116), ACE-27 (24/116), KFI (7/116), NCI-CI (3/116), ECI (2/116), and WUHNCI (1/116). The most frequently cited justification for calculating each CI (if provided) was: CCI for its validation in other studies, ACE-27 for its utility in cancer patients, and ECI for its comprehensive design. In general, the CCI and ACE-27 were predictive of mortality in HNS. The ECI was most consistent in predicting >1-year mortality. The ACE-27 and KFI were most consistent in predicting medical complications.

CONCLUSION

Despite inconsistencies in the literature, CIs provide insights into the impact of comorbidities on outcomes in HNS. These scores should be employed as an adjunct in the preoperative assessment of HNS patients. Comparative studies are needed to identify indices that are most reliable in predicting HNS outcomes.

Age and Comorbidities Impact Medical Complications and Mortality Following Free Flap Reconstruction

OBJECTIVE

Determine if age correlated with surgical or medical complications following head and neck free flap reconstruction.

STUDY DESIGN

Retrospective review of prospectively collected databases.

METHODS

Patients undergoing head and neck free flap reconstruction at three tertiary care institutions were included (n = 1972). Cohorts were based on age (<65, 65-75, 75-85, and >85). Outcomes reviewed operative duration, length of stay, surgical complications (free flap failure, fistula, hematoma, dehiscence, and infection), and medical complications (thromboembolism, stroke, cardiac, and pulmonary).

RESULTS

Anatomic site (P < .0001) and donor site varied by age (P < .0001). There was no difference in operative duration (P = .3) or length of hospitalization (P = .8) by age. The incidence of medical complications increased with increasing age. Pulmonary complication rates: <65 (3.9%), 65 to 75 (4.8%), 75 to 85 (7.1%), and >85 (11%) (P = .02). Cardiac complication rates: <65 (2.0%), 65 to 75 (7.3%), 75 to 85 (6.1%), and >85 (16.4%) (P < .0001). Mortality increased with age: <65 (0.4%), 65 to 75 (0.8%), 75 to 85 (1.1%), and >85 (4.1%) (P < .003). Medical complications correlated with mortality rates: pulmonary (3.5% vs. 0.6%; OR: 5.5; 95% CI: 1.5-20.0; P = .004); cardiac (3.3% vs. 0.6%; OR: 6.0; 95% CI: 1.6-21.8; P = .002); thromboembolism (4.6% vs. 0.7%; OR: 7.3; 95% CI: 1.6-33.6; P = .003); stroke (42% vs. 0.5%; OR: 149; 95% CI: 40-558; P < .0001); and sepsis (5% vs. 0.7%; OR 7.5; 95% CI: 1.0-60.5; P = .03). Age did not correlate with free flap success (P = .5), surgical complications (hematoma, P = .33; fistula, P = .23; infection, P = .07; and dehiscence, P = .37), or thirty-day readmission (P = .3).

CONCLUSION

Following free flap reconstruction, patient age did not correlate with development of a surgical complication. Patient age did correlate with development of a medical complication. Postoperative medical complications were found to correlate with perioperative mortality.

Safety of Reconstructive Microsurgery in the Elderly Population: a Multicentric Prospective Study

BACKGROUND

Safety of reconstructive microsurgery in elderly patients is still a topic of debate, because no conclusive evidence exists that provides indications and risk evaluation in elderly patients. The purpose of this study, which the Italian Society for Plastic, Reconstructive, and Aesthetic Surgery (SICPRE) has promoted, is to evaluate the safety and the complication risk of elective reconstructive microsurgery in elderly patients as well as to identify patient- or procedure-related risk factors. The secondary aim is to evaluate the predictive role for complications of the Geriatric 8 score (G8).

METHODS

A total of 194 consecutive patients from 18 centers, aged 65 or older, who received an elective microsurgical flap between April 2018 and April 2019 were prospectively evaluated. Patient-related, treatment-related, and outcomes data were recorded and statistically analyzed through multiple-adjusted logistic regression models.

RESULTS

Our study showed an increased risk of complications and a longer hospitalization in patients aged ≥75 years with the American Society of Anesthesiologists (ASA) score ≥3 (or G8 score ≤11) as compared to patients >65 years of age and <75 years of age who undergo reconstruction with a microsurgical flap. Instead, flap survival did not significantly vary with age, but was associated only with ASA score ≥3 (or G8 score ≤11) and surgeries that last longer than 480 min; however, flap survival (92.3%) was slightly lower than that commonly reported for in the general population.

CONCLUSIONS

Reconstructive microsurgery in the elderly is generally safe. The ASA score is easier and quicker than the G8 score and equally useful for risk stratification.

Major head and neck surgeries in the elderly population, a match-control study

BACKGROUND AND OBJECTIVES

To investigate complication rates in elderly cancer patients undergoing major head and neck surgeries.

METHODS

A retrospective, matched-control, analysis. For each elderly (≥70 years) patient, a younger, (<70 years) patients were matched based on sex, tumor location, disease stage, and operation time. Post-operative complication and survival analyses were performed.

RESULTS

Of 225 patients, 75 (33.3%) were elderly (mean age 76.2 (70-88) years) and compared with a match control group (53.2 (23-69) years). A higher rate of cardio-vascular comorbidity was noted in the elderly group (70.6% vs. 34%, respectively, P < 0.001). The majority (62.7%) of elderly patients required reconstruction with 24% receiving vascularized flap reconstruction. Total postoperative complication rate was 49.9% in the study versus 42.3% in the control group, with a major complication rate of 22.5% in the elderly versus 11.9% in the control group (P = 0.154). Mean follow-up was 41 (0-144) months. Five-year disease-specific (67.1% vs. 80.7%, P < 0.001) and overall survival rates (48.6% vs. 75.4%, P < 0.001) were significantly lower among elderly patients.

CONCLUSIONS

Major head and neck surgery in the elderly population does not entail higher complication rate, compared with younger patients, and should be allowed when curative intent is feasible and patient's general condition allows.

Association of Bolster Duration With Uptake Rates of Fibula Donor Site Skin Grafts

Importance

The fibula free flap donor site is associated with both short-term and long-term morbidity. Split-thickness skin graft (STSG) loss can lead to long delays in donor site healing and is associated with significant adverse sequelae. Patients may experience initial good STSG uptake after bolster removal but may have subsequent partial or total loss related to contact pressure or shearing.

Objective

To determine if increased duration of bolster use is associated with increased STSG uptake rates following fibula free flap reconstruction.

Design, Setting, and Participants

This retrospective cohort study included patients 18 years and older undergoing fibula free flap reconstruction following head and neck extirpative surgery at a tertiary care academic medical center from May 2013 to March 2019. The donor sites were photographed 4 weeks postoperatively, and areas of graft uptake were measured using image processing software. The baseline demographic, comorbidity, and operative characteristics were also collected.

Interventions

A fine mesh gauze with 3% bismuth tribromophenate and petrolatum blend bolster was sutured over leg STSGs placed on fibula free flap donor sites intraoperatively, and the ankle and lower leg were immobilized for 5 days in a plaster splint. Bolsters were either removed on postoperative day 5 or 14. Thereafter, the STSGs were covered with a petroleum and bismuth gauze and a cotton dressing.

Main Outcomes and Measures

Rates of donor site infection and STSG percentage uptake at 4 weeks.

Results

Of the 42 included patients, 31 (74%) were male, and the mean (SD) age was 62.1 (13.1) years. A total of 20 patients were included in the 5-day group, and 22 were included in the 14-day group. The 14-day bolster group had a higher mean percentage skin graft uptake rate compared with the 5-day bolster duration group (77.5% vs 59.9%), with an effect size of -0.632 (95% CI, -1.260 to -0.004). Patients with Adult Comorbidity Evalution-27 scores of 3 had poorer rates of STSG uptake compared with patients with Adult Comorbidity Evalution-27 scores of 0 to 2 (65.9% vs 82.9%), with an effect size of 0.599 (95% CI, -0.191 to 1.389). No donor site infections were noted in either group.

Conclusions and Relevance

Fourteen-day bolster application to the fibula free flap donor site was associated with better STSG uptake rates than 5-day bolster application.

Investigation of Free-Flap Transfer Reconstruction in Elderly Patients and Oral Intake Function

The authors retrospectively examined 39 patients with head and neck reconstruction using a free-flap transfer with microsurgery in elderly patients aged over 80 years in our hospital. They investigated postoperative local complications, postoperative systemic complications, day of ambulation, the presence of delirium, the postoperative oral intake ratio, and the reconstructive method in mandibular reconstruction patients. There were 12 postoperative local complications. And postoperative systemic complications were detected in 19 patients; however, 17 of these were respiratory disorders due to pneumonia. There were 17 patients with postoperative delirium. Oral intake was resumed after an average of 14.9 days. Of these, 34 patients were eventually able to eat some kind of food. The incidence of local complications in elderly free-flap reconstruction patients was similar to that in young people. However, the rate of systemic complications was much higher in elderly patients. The authors suggest that free-flap reconstruction can be performed relatively safely in elderly people when a detailed preoperative surgical plan.

How to select candidates for microvascular head and neck reconstruction in the elderly? Predictive factors of postoperative outcomes

INTRODUCTION

The proportion of elderly patients with head and neck cancer is increasing. However, predictive factors of postoperative outcomes are insufficiently explored in this population. In this study, we aimed to determine predictive factors of postoperative outcomes in elderly patients undergoing head and neck free-flap reconstructive surgery in order to determine criteria on which patient selection could be based.

METHODS

All patients aged 65 years or over who underwent head and neck free-flap reconstructive surgery at our institution, between 2000 and 2016, were included in this retrospective study. Predictive factors of postoperative outcomes were investigated in uni- and multivariate analysis.

RESULTS

Two-hundred patients were included in the study. Older age (>70, >75 or > 80 yrs) had no significant impact on postoperative outcomes. Free flap failure local and general complications rates were 11%, 34% and 43%, respectively. Oromandibular reconstruction (p = 0.04) was significantly associated with free flap failure and salvage surgery (p = 0.04) with local complications. A high comorbidity level (Charlson Comorbidity Index score ≥ 4; p = 0.02) was associated with a higher risk of general complications. A G8 (Geriatric 8 questionnaire) score < 15 (p = 0.004), a high comorbidity level (Kaplan-Feinstein Index score ≥ 2; p = 0.04) and oromandibular reconstruction (p = 0.04) were associated with poor swallowing function at 6 months.

CONCLUSION

Head and neck free flap reconstruction should be offered to fit (G8 score ≥ 15) elderly patients without severe comorbidities (KFI < 2 or CCI < 4), particularly when oral/pharyngeal soft-tissue reconstruction is planned.

Microsurgical head and neck reconstruction in patients with coronary artery disease: A perioperative assessment algorithm

BACKGROUND

With the rising number of patients in advanced age receiving microsurgical procedures, coronary artery disease (CAD) and its challenging management is of increasing importance. Evidence based data concerning morbidity and mortality are rare. We present our experiences with this highly selected patient population and propose a preoperative assessment algorithm.

PATIENTS AND METHODS

Between January 2006 and May 2016, a total of 57 patients with CAD received 58 free flaps. Median age of our patients was 64 years (interquartile range 57.5-70.0). Squamous cell carcinoma was the reason for reconstruction in all cases. Defect of the buccal, gum, tongue, lip, trigone, palatal, and hypopharyngeal regions were reconstructed. Patient characteristics and comorbidities were recorded. We especially focused on the preoperative cardiac assessment and treatment of patients who were scheduled for microsurgical free tissue transfer such as medical history, cardiac risk assessment, and further cardiac testing such as Doppler-echocardiography and myocardial perfusion assessment. Intraoperative course as well as postoperative morbidity and mortality was described.

RESULTS

About 54.4% of the selected cohort received cardiac catheterization due to a clinical preoperative cardiac assessment performed individually by the cardiologist on duty. In total, 52 fasciocutaneous anterolateral thigh flaps, four osteocutaneous fibula flaps, and two radial forearm flaps were performed. The flap survival rate was 96.6%. The overall surgical complication rate was 28.1% (16 patients), mostly due to wound infections (seven cases) and partial flap necrosis (four cases). Three patients died, resulting in a mortality rate of 5.2%.

CONCLUSION

CAD patients receiving head and neck microsurgical reconstructions are still at high risk for adverse consequences due to surgery. The microsurgical community is requested to share the experience of those cases in order to develop reliable and evidence based statements of the perioperative risks and prognosis for these patients. We additionally introduce a standardized perioperative cardiac assessment and treatment algorithm for head and neck surgery patients with CAD.
