Background: Pediatric odontogenic sinusitis (PODS) is a rare condition with limited research on its clinical features, diagnostic criteria, and treatment options. The current guidelines on pediatric rhinosinusitis do not mention a possible dental origin of the disease. This systematic review aims to summarize and analyze the existing literature on PODS, focusing on epidemiology, etiology, diagnostic tools, complications, treatment options, and outcomes. Methods: A systematic review was conducted following PRISMA reporting guidelines. Electronic searches were performed in multiple databases using keywords related to PODS and therapeutic strategies. Original articles reporting data on treatment outcomes for PODS were included. Results: The review highlighted the scarcity of high-quality evidence on PODS. The literature mainly consists of case reports and low-grade evidence studies. Limited data on the epidemiology, etiology, diagnostic tools, complications, and treatment outcomes of PODS in children are available. Conclusions: Further research is needed to better understand the clinical features, diagnosis, and treatment of PODS in pediatric patients. High-quality studies are required to establish evidence-based guidelines for the management of this condition, especially given the apparently high rate of complications when compared to adult ODS.

Introduction The aim of this study is to assess the impact of lymph node ratio (LNR) and number of positive lymph nodes (NPLN) on mortality and recurrence rates in patients with laryngeal squamous cell carcinoma. Materials and methods We conducted a retrospective multicenter international study involving 24 Otorhinolaryngology‐Head and Neck Surgery divisions. Disease‐specific survival (DSS) and disease‐free survival (DFS) were evaluated as the main outcomes. The curves for DSS and DFS according to NPLN and LNR were analyzed to identify significant variations and establish specific cut‐off values. Results 2507 patients met the inclusion criteria. DSS and DFS were significantly different in the groups of patients stratified according to LNR and NPLN. The 5‐year DSS and DFS based on LNR and NPLN demonstrated an improved ability to stratify patients when compared to pN staging. Conclusion Our data demonstrate the potential prognostic value of NPLN and LNR in laryngeal squamous cell carcinoma.
