Abstract

This comprehensive narrative review provides an overview of the current scientific evidence regarding maxillary sinus hypoplasia (MSH). This review highlights several variants of MSH that are relevant to implant planning and treatment in daily clinical practice. MSH is characterized by a reduction in sinus volume, which contrasts with maxillary sinus pneumatization, a condition that has received more clinical attention. Nevertheless, certain types of MSH can significantly impact implant surgery and the management of associated complications. The maxillary sinus volume can be affected by factors such as infection, trauma, genetic predispositions, and changes within the sinus or adjacent anatomical structures, including the nasal cavity and the ethmoid sinus. In cases of MSH, the maxillary sinus floor is positioned more cranially than the nasal floor, and the distance between the lamina papyracea of the eye and the middle meatus antrostomy point increases horizontally. Several variants of MSH potentially affect implant therapy. Chronic maxillary sinus atelectasis, which results from persistent ostium blockage, may have clinical implications, particularly when implant-related infections occur in the MS. Inferior meatus pneumatization involves a lateral expansion of the nasal cavity, requiring a nasal floor elevation procedure when placing implants in the posterior maxilla. Additionally, the formation of an ethmomaxillary sinus may create a septum-like structure in the distal area of the maxillary sinus, necessitating two separate bone access windows during the sinus floor elevation procedure. Given these considerations, it is crucial for clinicians to be aware of MSH. Accurate diagnosis of MSH requires the use of 3-dimensional radiography techniques, such as cone-beam computed tomography.

上颌窦发育不全与种植牙治疗相关的综述。
本文对上颌窦发育不全(MSH)的相关科学证据进行了综述。这篇综述强调了在日常临床实践中与种植计划和治疗相关的几种MSH变异。MSH的特点是窦体积减少,这与上颌窦充血形成对比,上颌窦充血得到了更多的临床关注。然而,某些类型的MSH可以显著影响种植体手术和相关并发症的处理。上颌窦的体积可受感染、外伤、遗传易感性、鼻窦或邻近解剖结构(包括鼻腔和筛窦)的变化等因素的影响。在MSH病例中,上颌窦底的位置比鼻底更靠颅,眼纸状膜与中鼻道口造口点之间的距离水平增加。MSH的几种变体可能影响种植体治疗。慢性上颌窦不张是由持续的口阻塞引起的,可能具有临床意义,特别是当ms中发生与种植体相关的感染时,下鼻道气化涉及鼻腔的外侧扩张,在上颌后缘放置种植体时需要鼻底抬高手术。此外,上颌窦的形成可能会在上颌窦的远端区域形成隔膜样结构,在窦底提升过程中需要两个单独的骨通道窗。考虑到这些因素,临床医生了解MSH是至关重要的。MSH的准确诊断需要使用三维放射技术,如锥束计算机断层扫描。
