O papel das variantes anatômicas do complexo ostiomeatal na rinossinusite crônica

Abstract

Currently, computed tomography is the method of choice for assessment of paranasal sinuses, nasal fossae and their anatomical variants. Presumably, these variations might induce osteal obstruction, preventing mucus drainage and predisposing to chronic rhinosinusitis. However, this concept is still controversial and the presence of any anatomical variant does not necessarily establish an etiology for rhinosinusitis. Among three subtypes of concha bullosa, only the bulbous type seems to be strongly associated with symptoms. Size and obliteration of osteomeatal complex drainage pathways may be relevant as well. Variations and tomographic signs of sinusal disease occurring on the same side reinforce the likelihood of interference with

The anatomical variations of the sinonasal region and its relationship with sinus diseases

“…Paradoks konka infundibulumda kompresyon ve sinüs obstrüksiyonuna neden olabilir (16) . Çok büyük ve diğer anatomik varyasyonlarla birlikte olması durumunda sinüzit etyolojisinde önemli olabileceği kabul edilir.…”

Frequency and volumetry of infraorbital ethmoid cells (Haller cells) on cone-beam computed tomograms (CBCT) of the mid-face

“…Different surveys studied miscellaneous patient groups varying in age, diseases, or for example ethnic groups [ 43 ], [ 46 ]. Some authors concluded that anatomical variations of the paranasal sinuses are progressively acquired with maturity [ 7 ]. We were not able to confirm or refute this conclusion due to the small sample size in our study, especially in terms of younger patients.…”

“…To date it is not known whether Haller cells develop during the embryonic period or later in life [ 7 ], [ 8 ]. Chimpanzees and possibly orang-utans show pneumatization in the ethmoid bone similar to humans, perhaps due to their upright posture.…”

The Importance of Three-Dimensional Imaging from CBCT in Elucidating a Well-Defined Radiolucency Image within the Maxillary Sinus: A Case Report

“…The paranasal sinuses begin to develop during the fetal period, in the third week of gestation, as invagination of the nasal mucosa into the lateral nasal wall, maxillae, frontal, ethmoid and sphenoid bones [1]- [3]. The maxillary sinus is the first sinus to develop; at birth, it is filled with fluid and becomes pneumatized [4]. The maxillary sinus can present anatomical variations such as pneumatization, antral septa, hypoplasia and exostosis [5].…”
