Incidence and risk factors of surgical site infection in patients with head and neck cancer: A meta-analysis.

We systematically review the incidence and risk factors of surgical site infection (SSI) in patients with head and neck cancer. PubMed, Embase, Cochrane Library, and Web of Science databases were searched to obtain studies on the risk factors for SSI in patients with HNC. The retrieval time was from the establishment of the database to February 2023. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias in included studies. Meta-analysis was performed by using Stata 15.1 software. A total of 32 articles including 128 919 patients with head and neck cancer and 2949 cases of SSI were included in this meta-analysis. The incidence rate of SSI in head and neck cancer ranges from 19% to 29%, and the overall infection rate was 24%. Meta-analysis indicated that BMI < 20 kg/m2 (OR, 2.64; 95% CI, 1.74-4.00; I2 , 0%), diabetes (OR, 3.00; 95% CI, 2.12-4.16; I2 , 60.6%), ASA score (OR, 1.51; 95% CI, 1.29-1.77; I2 , 0%), radiotherapy (OR, 2.27; 95% CI, 1.87-2.77; I2 , 44.8%), chemotherapy (OR, 2.36; 95% CI, 1.64-3.40; I2 , 0%), clindamycin antibiotic (OR, 2.99; 95% CI, 1.82-2.93; I2 , 36.5%), deficit repair (OR, 3.76; 95% CI, 1.22-11.59; I2 , 91.4%), neck dissection (OR, 2.13; 95% CI, 1.63-2.79; I2 , 16.4%), blood transfusion (OR, 2.29; 95% CI, 1.52-3.45; I2 , 66.2%), mandibular (OR, 3.17; 95% CI, 1.85-5.42; I2 , 73%), tracheostomy (OR, 2.51; 95% CI, 1.74-3.62; I2 , 86.4%), operation time (OR, 1.42; 95% CI, 1.16-1.74; I2 , 86.4%), ALB (OR, 2.48; 95% CI, 1.95-3.15; I2 , 5.3%) were risk factors of surgical site infection in patients with head and neck cancer (p < 0.05). The results of the sensitivity analysis showed good agreement in all risk factors and the results had stability. The present meta-analysis suggests that BMI < 20 kg/m2 , diabetes, ASA score, radiotherapy, chemotherapy, clindamycin antibiotic, deficit repair, neck dissection, blood transfusion, mandibular, tracheostomy, operation time, and ALB were significant risk factors for SSI.

Autologous Fat Grafting for Functional and Aesthetic Improvement in Patients with Head and Neck Cancer: A Systematic Review.

INTRODUCTION: The efficacy and safety of autologous fat grafting for use in oncology patients are controversial. Patients with head and neck cancer have complex anatomy and require reconstructive repair of the head and neck after comprehensive treatment. The limited additional aesthetic and functional studies on the use of autologous fat fillers in patients with head and neck cancer are unclear. This study systematically evaluates the additional function of autologous fat fillers in the head and neck and systematically reviews issues related to autologous fat grafting after comprehensive head and neck cancer treatment, including current indications, techniques, potential complications, graft survival, and patient satisfaction. METHODS: A systematic literature review was performed using PubMed, The Cochrane Library, EMBASE, and Web of Science (last accessed on January 9, 2023). RESULTS: A total of 249 cases of autologous fat fillers in patients with head and neck cancer were reported in 10 clinical publications. Observations were based mainly on subjective physician and patient evaluation indicators, and all studies reported the beneficial effects of autologous fat fillers on aesthetics and function after treatment for head and neck cancer. CONCLUSIONS: Autologous fat fillers are effective in improving the aesthetics and function of head and neck cancer, and due to the limitations of the original study, future studies with large samples are needed to support this.
