Villela CLBC et al. / Variações anatômicas dos seios paranasais
CONCLUSÃO
A avaliação radiológica das estruturas nasossinusais
deve ser realizada nos pacientes com indicação de cirurgia
endoscópica funcional endonasal, para demonstrar
o sítio e extensão da doença, bem como o detalhamento
da anatomia local. O estudo por TC dos seios paranasais
e suas reconstruções multiplanares é fundamental por
permitir um planejamento cirúrgico seguro.
O conhecimento da anatomia, das variantes dos seios
paranasais e suas relações com condições patológicas é
uma habilidade que se espera do radiologista.

Abstract. Anatomical variations of paranasal sinuses: what to inform
the otolaryngologist?
Anatomic variations of paranasal sinuses are common findings in
daily practice. For a radiologist, to know these variations is necessary
because of the pathological conditions related to them, and
also because they are import for planning a functional endoscopic
endonasal surgery, the procedure of choice for diagnosis, biopsy
and treatment of various sinonasal diseases. To assure that this
surgery is done safely, preventing iatrogenic injuries, it is essential
that the surgeon has the mapping of these structures. Thus, a
CT is indispensable for preoperative evaluation of paranasal sinuses.
Since a general radiologist is expected to know these
changes and their relationship to pathological conditions, a literature
review and a iconographic essay were conducted with the aim
of discussing the importance of major anatomic variations of
paranasal sinuses.
