Trigonocephaly involves premature fusion of both the metopic suture and the sutures in the skull base. Surgical treatment by opening of the prematurely fused metopic suture and expansion of the anterior cranial base by creating "neosutures" was used to treat three children with trigonocephaly. The combination of lateral canthal advancement and radical forehead remodeling achieved excellent results. These procedures can also prevent the development of midface hypoplasia such as hypotelorism. The two younger patients, aged 0 and 6 months, achieved rapid bone growth in the defects and normalization of intercanthal and interpupillary distances. The older patient, aged 8 years, retained some skull defects at follow-up. The optimal age for surgery is 3-6 months, which allows good cosmetic results and minimizes visual repercussions with relatively low perioperative risks.
三角头畸形涉及额缝和颅底缝线过早融合。通过打开过早融合的额缝并通过创建“新缝线”来扩张前颅底的手术治疗方法被用于治疗三名三角头畸形患儿。内眦移位术和彻底的前额重塑相结合取得了优异的效果。这些手术还可以预防中面部发育不全的发展，如眼距过窄。两名年龄分别为0个月和6个月的较年轻患者在缺损处实现了快速骨生长，内眦间和瞳孔间距离恢复正常。年龄较大的患者，8岁，随访时仍有一些颅骨缺损。手术的最佳年龄是3至6个月，这能带来良好的美容效果，并将视觉影响降至最低，同时围手术期风险相对较低。
