Abstract

안면중앙부 골절 환자 44명의 Waters사진 44매와 전산화단층사진 88매(횡단면 44매, 관상
면 44매)를 3명의 치과방사선과 전공자와 3명의 비전공자가 3가지 방법으로 판독한 후 수술
소견을 절대기준으로 하여 각각의 ROC값을 구하여 다음과 같은 결과를 얻었다.
1. 전공자군과 비전공자군 모두에서 Waters 방사선사진만을 이용한 경우보다 전산화단층
사진만을 이용하거나 두 가지를 다 이용한 경우에 진단능이 높았으나(p<0.05) 전산화단층사
진만을 이용한 경우와 두가지를 동시에 이용한 경우에는 유의한 차이가 없었다.
2. 전반적으로 양 군 모두에서 상악동 측벽에 대한 진단능이 가장 높았으며 후벽에 대한
진단능이 가장 낮았다(p<0.05).
3. 전공자군에서는 상악동 전벽 판독시 전산화단층사진만을 이용한 경우에도 진단능이 증
가되었으나 내벽, 외벽, 상벽에서는 Waters 방사선사진과 전산화단층사진을 함께 판독한 경
우에만 증가되었다.
4. 비전공자군에서는 상악동 전벽과 내벽 판독시 전산화단층사진만을 이용한 경우에도 진
단능이 증가되었으나 후벽, 측벽, 상벽에서는 3가지 판독 방법간에 유의한 차이가 없었다.
5. 모든 판독 방법과 판독 부위에서 전공자군의 진단능이 비전공자군보다 높았다(p<0.05).

This study was intended to compare the diagnostic ability between Waters' radiograph
and CT in the diagnosis of midfacial fracture. The study group included 44
patients(male:32, female :12, age range :16-74 years old) with facial injury who
underwent surgery.
Waters' radiograph and both axial and coronal scanning were performed before
surgery. Three oral radiologists and three non-oral radiologist interpreted 44
Waters'radiographs and 88 CT in three ways ; 1) interpretation using Waters'radiograph
only, 2) interpretation using CT only, 3) interpretation using Waters'radiograph and CT.
The interpretation sites were confined to the walls of maxillary sinus; anterior,
posterior, medial, lateral and superior wall. ROC curves were made with the findings
during surgery as a gold standard except the posterior wall, where the joint evaluation
of Waters'radiograph and CT by other three oral radiologists was used.
ROC areas were compared according to the interpreting methods, the interpretation
sites, and groups (R group ; oral radiologist group, N group ; non-oral radiologist
group).
The obtained results were as followed :
1. The diagnostic ability of CT only and Waters'radiograph and CT was higher than
Waters'radiograph only in both groups(P<0.05). But there was no difference between CT
only and Waters'radiograph and CT.
2. Generally, the diagnostic ability for the lateral antral wall was the highest and that
for the posterior antral wall was the lowest in both groups(P<0.05).
3. In R group, for the anterior antral wall the diagnostic ability using CT only was
increased but for the medial, lateral and superior antral walls the diagnostic ability was
increased in only using Waters'radiograph and CT.
4. In N group, for the anterior and medial walls the diagnostic ability using CT only
was increased. But for the posterior, lateral and superior antral walls there were no
difference among three interpreting methods.
5. The diagnostic ability of R group was higher than N group in all interpreting
methods.
