Inflammation-Based Score (Combination of Platelet Count and Neutrophil-to-Lymphocyte Ratio) Predicts Pharyngocutaneous Fistula After Total Laryngectomy.

OBJECTIVES/HYPOTHESIS: Postoperative complications may depend on the systemic inflammatory response. We evaluated the predictive potential of the combination of platelet count and neutrophil-to-lymphocyte ratio (COP-NLR) for the incidence of pharyngocutaneous fistula (PCF) in patients who have undergone total laryngectomy. STUDY DESIGN: Retrospective cohort study. METHODS: Patients who underwent total laryngectomy between 2000 and 2020 were recruited from four hospitals. The correlations between the incidence of PCF and several risk factors, including the COP-NLR, were examined. Patients with both elevated platelet count and elevated neutrophil-to-lymphocyte ratio (NLR) were categorized as COP-NLR 2, and patients with either one or no abnormal values of both parameters were assigned as COP-NLR 1 and COP-NLR 0, respectively. RESULTS: A total of 235 patients were identified. The overall incidence of PCF was 12.3%. The cut-off value for NLR before surgery was set at 3.95 (sensitivity = 58.6%, specificity = 69.4%, area under the curve [AUC] = 0.635), and the platelet count was set at 320 × 109 /L (sensitivity = 27.6%, specificity = 87.9%, AUC = 0.571). Multivariate analysis revealed that COP-NLR was an independent risk factor for PCF (COP-NLR 1 vs. COP-NLR 0: odds ratio [OR], 4.17; 95% confidence interval [CI], 1.64 to 10.59; and COP-NLR 2 vs. COP-NLR 0: OR, 5.33; 95% CI, 1.38 to 20.56). CONCLUSIONS: COP-NLR is a novel predictive factor for the development of PCF in patients undergoing total laryngectomy. LEVEL OF EVIDENCE: 4 Laryngoscope, 132:1582-1587, 2022.

Bezold's abscess in a diabetic patient without significant clinical symptoms.

A 52-year-old Japanese man with a history of type 2 diabetes mellitus (DM) presented with mild dizziness. On admission, the physical examination only revealed tachycardia and right sided cervical lymphadenopathy. On the fifth day of admission, his mental status slightly worsened. Urgent Computed Tomography (CT) of the head and neck revealed multiple abscesses spreading from the right temporal bone to the right sternocleidomastoid muscle. Bezold's abscess was diagnosed. Streptococcus pneumoniae was isolated from middle ear fluid and blood cultures. Bezold's abscess has rarely been described in the era of antimicrobial therapy. However this abscess can still occur in patients without any typical severe symptoms. Repeated history taking and thorough physical examination can help detect Bezold's abscess.
