Odontogenic and rhinogenic chronic sinusitis: a modern microbiological comparison

摘要: Background Odontogenic sinusitis and sinonasal complications of dental disease or treatment (SCDDT) play a relevant, often underappreciated role in paranasal sinus infections. Treating SCDDT patients requires tailored medical surgical approaches order to achieve acceptable success rates. These differ from common rhinogenic protocols mostly because the different etiopathogenesis. Our study comprehensively evaluated microbiology antibiotic resistance compared findings with control group affected by sinusitis. Methods We performed microbiological sampling during surgery on 28 16 chronic rhinosinusitis nasal polyps (CRSwNP). Colonies were isolated, Gram-stained, species identified using classic biochemical methods. results confirmed DNA pyrosequencing, then profile each isolate various antibiotics was tested. Results Microbial growth observed all patients, whereas samples 60% failed yield any bacterial (p < 0.001). Anaerobes grew 14% as 7% CRSwNP = 0.42). Of isolates 70% susceptible amoxicillin/clavulanate, levofloxacin, teicoplanin, vancomycin. staphylococci identified, 80% capable producing beta-lactamase. Conclusion Given extent contamination within maxillary these infections should be regarded class conditions sinusitis. support need for patients.
