RESUMO
Resumo A introdução da cirurgia endoscópica sinusal funcional na década de 80 proporcionou uma mudança drástica no tratamento de pacientes com rinossinusite, melhorando a qualidade de vida mediante a retirada de processos patológicos ou variações anatômicas que provocam obstrução nas vias de drenagem dos seios paranasais. Porém, apesar do uso rotineiro da tomografia computadorizada na avaliação anatômica dos seios paranasais, a maioria dos laudos radiológicos ainda carece de informações que orientem o planejamento cirúrgico. O objetivo deste ensaio iconográfico é demonstrar, por meio de tomografia computadorizada, as principais variações anatômicas dos seios paranasais, cujo reconhecimento é fundamental para o planejamento pré-operatório, a fim de evitar falhas terapêuticas e iatrogenias.Abstract The introduction of functional endoscopic sinus surgery in the 1980s brought about a drastic change in the treatment of patients with rhinosinusitis, improving quality of life through the removal of pathological processes or anatomical variations that obstruct the drainage pathways of the paranasal sinuses. However, despite the routine use of computed tomography in the anatomical evaluation of the paranasal sinuses, most radiological reports still do not provide sufficient information to guide the surgical planning. The objective of this pictorial essay was to demonstrate, through computed tomography, the main anatomical variations of the paranasal sinuses, the recognition of which is fundamental for preoperative planning, in order to avoid treatment failure and iatrogenic complications.
