Aim: To present the most recent evidence about odontogenic sinusitis. Materials and methods: An electronic search was conducted in MEDLINE via OVID, Embase via OVID and PubMed for odontogenic sinusitis. Results: Odontogenic sinusitis originates from pathology of the dentition and surrounding structures. This disease differs from sinusitis of other causes in pathophysiology, diagnosis, microbiology and management. Symptoms of unilateral nasal obstruction and purulent discharge are highly suggestive of the disease. Computed tomography is considered the gold standard in assessing the relationship between dental conditions and sinus disease. Failure to eliminate the dental source of infection will often result in treatment failures. Collaboration and multidisciplinary management between dental surgeons and otolaryngologists is imperative for the successful identification and treatment of the disease, as either treatment in isolation may be inadequate leading to poor patient outcomes. Primary dental treatment may be effective in patients with lower sinonasal disease burden and similarly, patients suffering from minimal dental disease may recover from sinus surgery alone. Combined dental and sinus surgery results in disease resolution in 90%–100% of patients; however, controversy remains regarding the optimal sequence of interventions. Conclusion: This review describes the aetiological, microbiological, clinical findings and diagnostic methods, as well as clinical and patient factors influencing treatment modalities of odontogenic sinusitis. Furthermore, a management decision tree is provided. [ABSTRACT FROM AUTHOR]

Objective: Carcinoma ex pleomorphic adenoma (CXPA) is a rare malignant salivary gland tumor. Although multiple reviews have been published on salivary gland malignancies, it has been a decade since the last dedicated systematic review pertaining to CXPA alone was published. This study examines molecular factors in CXPA diagnosis. Data Sources: MEDLINE, CINAHL, Embase, Scopus, Web of Science (BIOSIS), Cochrane CENTRAL, Health Collection (Informit), OpenDOAR, and GreyNet International. Review Methods: Systematic review and meta‐analysis from inception to October 31, 2022 for all English language studies pertaining to "carcinoma ex pleomorphic adenoma." Predicted incidence of each biomarker was calculated with meta‐analysis. Comparison against pleomorphic adenoma (PA) and salivary duct carcinoma (SDC) when reported within the same study are performed. Risk of bias performed with JBI tool for prevalence studies. Results: Of 19151 unique studies undergoing abstract screening, 55 studies (n = 1322 patients) underwent data analysis. Biomarkers with >3 studies were p53, HER2, AR, EGFR, PLAG1, ERBB, ER, PR, HMGA2, p16, p63, a‐SMA, RAS, PTEN, PDL1, BRAF, PIK3CA, and c‐kit. Highest incidence was seen in AR, EGFR, p16, and p53. Significant differences were demonstrated compared with PA and SDC. There was high heterogeneity and overall high risk of bias within studies. Conclusion: Molecular factors are an area of interest in the diagnosis of CXPA. Our study results support examining CXPA as a discrete cohort in future targeted therapy trials.

Introduction: Early laryngeal carcinomas may be treated by transoral laser microsurgery (TLM) or external beam radiotherapy. We review our experience of surgical treatment of laryngeal pre-malignant and malignant lesions over the past 15 years in a high-volume head neck unit. Methods: A review of a prospective patient database of patients with laryngeal SCC, who were treated with CO2 TLM between 2004 and 2019 was carried out. Results: 83 patients with a mean age of 67.7 (SD: 10.6) years underwent primary curative TLM for T1a/b SCC. 5-year overall survival was 93.2% (95%CI 86.9–100%), disease free survival was 86.0% (95%CI 78.1–94.6%), locoregional control was 91.2% (95%CI: 85.1–97.7%) and larynx preservation rate of 95.1% at 5 years. Conclusion: TLM is an excellent treatment modality for T1 early glottic SCC, with excellent locoregional control and disease-free survival. It is minimally invasive, outpatient-based, and cost-effective procedure preserving upper aerodigestive tract dysfunction for all activities of daily living. [ABSTRACT FROM AUTHOR]

In certain instances, patients who underwent endoscopic laser excision (ELE) for biopsy-proven early glottic carcinoma do not show any evidence of carcinomatous cells on histopathologic analysis. Our study aims to determine the incidence of this phenomenon. A retrospective analysis of patients with biopsy-proven early glottic squamous cell carcinoma who underwent ELE was conducted. 121 patients with a mean age of 68.2 ± 10.7 were included in this study. Initial biopsy showed carcinoma in situ in 38 patients, (31.4%), T1a in 41 patients (33.9%), and T1b in 42 patients (34.7%). Following ELE, a pathologically negative excision was seen in 26 patients (21.5%). Disease recurrence occurred in 3 patients who had a pathologically negative excision (11.5%). Following repeat ELE, all patients remained disease free. A significant number of early glottic carcinoma present with small volume disease which may be eradicated with diagnostic biopsy alone.
