Hello, colleagues. Before you is Chapter 9 — odontogenic maxillary sinusitis. This is a classic interdisciplinary pathology where the oral and maxillofacial surgeon works at the intersection with otorhinolaryngology. The root of the problem always lies in the anatomical proximity of the apices of the maxillary premolars and molars to the sinus floor.
The section consists of three key blocks: the clinical presentation of the disease itself, the nuances of differential diagnosis (primarily with rhinogenic forms and radicular cysts), and surgical treatment tactics — ranging from closure of oroantral communications to radical antrostomy and modern endoscopic techniques.
During tests and exams, three things are evaluated most strictly: reading CBCT scans (the ability to identify mucosal thickening and foreign bodies in the sinus), a clear algorithm of action in case of accidental perforation of the sinus floor during tooth extraction, and the rationale for choosing the surgical intervention method. Study the material thoroughly — you will inevitably encounter this pathology in the very first years of independent practice.
