The intimate position of the maxillary sinus to the apices of teeth creates problems if periapical inflammation occurs. This can lead to a perforation into the sinus and cause sinusitis. Persistent and complicated situations that do not respond after nonsurgical root canal treatment demand a suitable surgical therapy. Knowledge of the specific anatomic conditions, an adequate diagnosis, and an appropriate surgical procedure facilitate success rates that are comparable with those obtained in other regions, even in unfavorable initial conditions.
上颌窦与牙根尖的紧密位置关系，若发生根尖周炎则会引发问题。这可能导致上颌窦穿孔并引起鼻窦炎。非手术根管治疗后无反应的持续性和复杂性情况需要合适的手术治疗。了解特定的解剖状况、进行充分诊断以及采取恰当的手术操作，即便在初始条件不利的情况下，也能使成功率与其他区域相当。
