摘要

目的:评估牙源性眼眶蜂窝织炎的放射学特征和临床结果:牙源性眼眶蜂窝织炎的多中心回顾性研究。评估的主要结果包括致病菌、临床症状、放射学结果、处理和视觉结果:共发现四名牙源性眼眶蜂窝织炎患者。其中男性和女性比例相当,平均年龄为43岁(25-56岁)。所有患者均出现眶隔综合征,视力为数手指(1例,25%)、手部活动(1例,25%)和无光感(2例,50%)。病原菌为毫雷链球菌(3 例,75%)和星座链球菌(1 例,25%)。核磁共振成像结果显示,所有病例均存在骨膜下脓肿,其放射学特征为T1高密度、T2微高密度,弥散受限,表观弥散系数信号低。最终视力从 6/6 到无光感不等。一名患者因广泛坏死伴败血症和全身情况恶化而需要进行眼眶外翻手术:结论:牙源性眶蜂窝织炎具有视力丧失的严重风险,并有继发于链球菌的眶隔综合征的倾向。结果变化很大,有两个病例发展到失明,其中一个需要进行眶外扩张术。

Clinical and radiological characteristics of odontogenic orbital cellulitis.

Purpose: To assess the radiological features and clinical outcomes of odontogenic orbital cellulitis.

Method: Multi-centre retrospective study of odontogenic orbital cellulitis. Primary outcomes assessed were causal organism(s), clinical signs, radiological findings, management and visual outcomes.

Results: Four patients with odontogenic orbital cellulitis were identified for inclusion. There was an equal proportion of men and women with a mean age of 43 years (range 25-56 years). All patients presented with an orbital compartment syndrome, with visual acuity of counting fingers (n = 1, 25%), hand movements (n = 1, 25%) and no perception of light (n = 2, 50%). The organisms implicated were Streptococcus milleri (n = 3, 75%) and Streptococcus constellatus (n = 1, 25%). MRI findings showed a subperiosteal abscess was present in all cases, which was characterised radiologically as a T1-hyperintense, T2 minimally hyperintense collection with restricted diffusion and a low apparent diffusion coefficient signal. Final visual acuity ranged from 6/6 to no light perception. One patient required an orbital exenteration due to extensive necrosis with sepsis and systemic deterioration.

Conclusions: Odontogenic orbital cellulitis carries a serious risk of vision loss with a propensity to present with an orbital compartment syndrome secondary to Streptococcus species. Outcomes were highly variable, with two cases progressing to blindness of which one required an orbital exenteration.
