Maxillary sinus hypoplasia (MSH) is an uncommon clinical entity that represents a persistent decrease in sinus volume resulting from a centripetal retraction of the maxillary sinus walls. Pathophysiology of MSH is still controversial. Obstruction of the maxillary sinus ostium and negative pressure in the sinus has been mostly implicated in the development of MSH in most of the reported cases. We present a case of progressive unilateral MSH, which has an open ethmoid infundibulum and also presence of an open accessory ostium on the same side. Based on these findings, we propose that ventilatory dysfunction resulting from ostial obstruction alone cannot be accepted as the primary and sole etiologic factor in the pathogenesis of MSH.
上颌窦发育不全（MSH）是一种不常见的临床病症，表现为上颌窦壁向心性回缩导致窦腔容积持续减小。MSH的病理生理学仍存在争议。在大多数报道的病例中，上颌窦口阻塞和窦腔内负压大多被认为与MSH的发生有关。我们报告一例进行性单侧MSH病例，该病例筛漏斗开放，同侧还有一个开放的副口。基于这些发现，我们提出，仅由口阻塞导致的通气功能障碍不能被视为MSH发病机制中的主要和唯一病因。
