We report a case of a temporal bone pneumatocele with full-thickness erosion of the cranium associated with aggressive nose blowing. This condition presented 9 years after traumatic fracture of the temporal bone. There are 17 reported cases of mastoid sinus hyperpneumatisation in the literature. Eleven of the 17 are associated with Valsalva manoeuvres or elevated middle ear pressure. However, no other cases of full-thickness erosion at the site of a former fracture have been reported. We propose that the fracture, in combination with elevated mastoid sinus pressure from aggressive nose blowing, led to escape and trapping of pressurised air in the epidural and subcutaneous spaces, which resulted in bone erosion.
我们报告了一例颞骨气泡性骨瘤病例，伴有颅骨全层侵蚀，与剧烈擤鼻有关。这种情况发生在颞骨外伤性骨折后 9 年。文献中有 17 例乳突窦过度充气的报道。其中 17 例中的 11 例与瓦尔萨尔瓦动作或中耳压力升高有关。然而，没有报告其他以前骨折部位全层侵蚀的病例。我们提出，骨折加上剧烈擤鼻引起的乳突窦压力升高，导致受压空气逸出并困在硬脑膜和皮下间隙，导致骨质侵蚀。
