Objective Infection prevention is crucial in head and neck cancer surgery due to the high risk of surgical site contamination by oral bacteria and pharyngeal secretions. The coronavirus disease 2019 (COVID-19) pandemic has introduced significant challenges to infection control in medical settings, including restrictions on patient care and changes to perioperative management. This study investigated the incidence of postoperative pneumonia (PP) and surgical site infection (SSI) before and during the COVID-19 pandemic, and examined how perioperative oral care and oral hygiene status were associated with the occurrence of postoperative infections. Methods We retrospectively reviewed the medical records of patients who underwent head and neck cancer surgery between January 2018 and March 2022. The incidences of PP and SSI were compared before and during the COVID-19 pandemic. In addition, variables identified by univariate analysis as predictors of postoperative infection were incorporated and examined using logistic regression analysis. Results A total of 213 patients were included in this study. The incidence rates of PP and SSI were 15.0% and 24.4%, respectively, with no statistically significant difference before and during the pandemic. The risk factors for PP included preoperative oral dryness (odds ratio [OR] = 2.65; 95% confidence interval [CI] = 1.14–6.17; p = 0.024), and diabetes (OR = 2.65; 95% CI = 1.04–6.72; p = 0.040), while for SSI, the risk factors included lack of postoperative oral care (OR = 0.29; 95% CI = 0.10–0.86; p = 0.026), prolonged operative time (OR = 1.80; 95% CI = 1.09–2.99; p = 0.022), and preoperative radiotherapy (OR = 2.25; 95% CI = 1.02–4.95; p = 0.044). Conclusion Appropriate perioperative oral care remains essential, even in the post-COVID-19 era. This study highlights the importance of preventing oral dryness before surgery and ensuring continuous professional oral care before and after surgery to prevent postoperative infections.

当院で2018年1月～2022年3月に頭頸部癌手術を受けた患者のうち、新型コロナ流行前(2018年1月～2019年6月)に受けた102例と、流行後(2020年6月～2022年3月)に受けた102例を対象とし、術後肺炎および手術部位感染(SSI)の発生率を流行前後で比較した。結果、術後肺炎の発生率は流行前16.7%、流行後13.7%、SSIの発生率は流行前22.5%、流行後20.6%で、いずれも有意差はなかった。術後肺炎・SSIの発生に関連する因子について、「口腔衛生状態」を含めて多重ロジスティック回帰分析を行った結果、術後肺炎の発生に関連する有意な因子として「出血量」、SSIの発生に関連する有意な因子として「術前放射線療法」「再建術」が抽出され、「口腔衛生状態」は有意な因子ではなかった。
