ABSTRACT

Background and Objectives: Sensitivity and specificity of an ABR screening procedure are higher than those achieved using OAE-based newborn hearing screening. However, the time for preparation and ABR recording is longer than required for OAE. The aim of our study was to develop a quicker ABR screening algorithm. A new, fast screening algorithm based on ABR recorded at a high click repetition rate is proposed. Patients and Methods: The 5 normal hearing adults participated in the preliminary study. 52 normal neonates (142 ears) and 23 high risk neonates (46 ears) have been screened using click stimuli ABR with high repetition rate from Sep.2003 through Mar.2005. The test was satisfactory when a pass result was attained (stage 1 ). When the infant woke soon after the testing began, a new start was made. Such incidences were counted, but were not included in the specificity calculation. When after the measurement period of 120 seconds the summation curve was close to being a pass, the measurement was repeated and regarded as a retest (stage 2) . Based on these data, the following aspects were evaluated: test time (preparation and recording time) , pass rate, refer rate and specificity. Results: Preparation and recording time of stage 1 were 14.2 seconds and 33.2 seconds, those of stage 2 were 6.1 seconds and 33.4 seconds, respectively. The pass rates of two stages were 95.3% and 85.7%, the refer rates of two stages were 4.6% and 14.2%, respectively. The specificity of stage 1 was 95.3%. Conclusion: ABR with high click repetition rate for universal newborn hearing screening is less time consuming, efficient, and reliable screening method. (J Clinical Otolaryngol 2005;16:79–83)

다음은 갑상선 로봇수술 사진이다. 다음 설명 중 틀린 것은?

 

1. 이 접근법은 Mental nerve injury의 가능성이 있어 mental nerve를 찾아 위치를 확인 후 수술한다.

2. 일반적으로 이산화탄소를 주입해서 공간을 확보하므로 합병증으로 CO2 embolism 발생 가능성이 있다.

3. 다른 부위로의 접근법에 비해 절제하고자 하는 부위에 빨리 도달할 수 있다.

4. 합병증으로 다른 부위로의 접근법에 비해 수술 부위 감염 가능성이 있다.

5. 합병증으로 다른 부위 접근법에 비해 구강이나 턱, 경부 등에 피부 천공이나 화상 등이 드물게 발생할 수 있다.

 

정답 ①

해설

Transoral thryoidectomy의 합병증으로 다른 접근법보다 CO2 embolism,
surgical site infection, skin perforation,burn risk rate 가 높다.
Metal nerve injury risk가 있어 구강전절절개를 safety zone에 해야 한다.
