[Analysis of p53 gene mutation in salivary adenoid cystic carcinoma.].

Purpose: The purpose of this study was to investigate the occurrence of p53 gene mutation in salivary adenoid cystic carcinoma, the correlation between the gene and prognostic significance.

Methods: A series of salivary adenoid cystic carcinoma were studied by polymerase chain reaction and single strand conformation polymorphism (PCR-SSCP) analysis to detect p53 mutation, respectively.

Results: The result showed that p53 gene mutations in exon 5-8 were detected in 65.

[Sphenozygomatic suture as a guide in the reduction of zygomatic fracture].

Objective: To investigate the effectiveness of sphenzygomatic suture as a guide in the reduction of zygomatic complex fracture.

Methods: 36 cases of zygomatic complex fracture according to Zingg classification were treated. Reduce sphenozygomatic suture first, then reduce the other fracture line and fixed with titanium micro-plates.
