Abstract

UNLABELLED

The complex anatomy of the frontoethmoidal recess, as well as its anatomical relationship with the vital adjacent structures in the region explain the reason for considerable surgical care to protect these structures and minimize complications related to healing. Trephination is an accepted procedure to access the frontal sinus.

AIM

Discuss the best location for performing frontal sinus trephination.

METHODS

Measuring sinus frontal depth at 3 points equidistant to the midline (crista galli) through the axial tomographic sections.

RESULTS

We measured 138 frontal sinus (69 patients). Frontal sinus depth at 0,5 cm was statistically larger than 1 cm and 1.5 cm, as well as the 1 cm trephine point was significantly larger than 1.5 cm (12.22+/-4.25 vs 11.78+/-4.65 p<0,05; 12.22+/-4.25 vs 10.78+/-5.98 p<0.001; 11.78+/-4.65 vs 10.78+/-5.98 p<0.05). The trephine set used (maximum depth of penetration of 0.7 cm) is safe to be applied in approximately 80% of the patients.

CONCLUSION

Analyzing the results, the trephination may be performed at variable points of the frontal sinus, but the distance of 1 cm from midline appears to be safer and shows better aesthetic results.

摘要

未标注

额筛隐窝的解剖结构复杂，以及它与该区域重要相邻结构的解剖关系，解释了为何在手术中需要格外小心以保护这些结构并尽量减少与愈合相关的并发症。环钻术是一种公认的进入额窦的手术方法。

目的

探讨进行额窦环钻术的最佳位置。

方法

通过轴向断层扫描在距中线（鸡冠）等距的3个点测量额窦深度。

结果

我们测量了138个额窦（69例患者）。0.5厘米处的额窦深度在统计学上大于1厘米和1.5厘米处，并且1厘米处的环钻点明显大于1.5厘米处（12.22±4.25 对比 11.78±4.65，p<0.05；12.22±4.25 对比 10.78±5.98，p<0.001；11.78±4.65 对比 10.78±5.98，p<0.05）。所使用的环钻装置（最大穿透深度为0.7厘米）对大约80%的患者应用是安全的。
