부비동 내시경 수술에서 Cone Beam Computed Tomography의 유용성
우원근,이용배,정도광,신우철,이상덕 대한비과학회 2012 Journal of rhinology Vol.19 No.1
Background and Objectives : Cone beam CT is a relatively new radiologic technique for head and neck imaging,and is widely used in dentistry to plan implant procedures. Compared to conventional CT, it has greater spatial resolution, a lower radiation dose (about 10% that of conventional CT), and lower cost. The objective of this study was to evaluate the utility of cone beam CT for endoscopic sinus surgery. Subjects and methods : A total of 50 patients were involved. Endoscopic sinus surgery was performed unilaterally under local anesthesia, so we used the half Lund-Mackay score to quantify preoperative CT findings. The intraoperative severity score was also determined, and the relationship between the preoperative Lund-Mackay score and intraoperative severity was assessed. The subjective level of operator satisfaction was scored on a ten-point visual analogue scale in terms of four items: overall satisfaction, disease extent of each sinus, identification of anatomic landmarks, and distinction of soft tissue characteristics. Results : The preoperative half Lund-Mackay score was 5.26 and the intraoperative severity score was 5.02; these two scores were significantly correlated (p < 0.01). The level of overall operator satisfaction was relatively high (9.04/10). Conclusion : Cone beam CT is a useful imaging method for preoperative evaluation of endoscopic sinus surgery.

Backgrounds and Objectives:Sore throat due to acute pharyngitis is one of the most comon ailments and complaints for hospital visits. This report aims to study the effects of oral steroids on pain relief, duration of illness, to get bacterial culture result and its relation to therapeutic efect. Materials and Method:Data was collected from 109 patients who have been clinicaly diagnosed with acute pharyngitis from March 2002 to August 2002. The 109 patients were arbitrarily divided into 3 groups and each group was prescribed different combinations of oral steroid and NSAIDS. All groups were commonly prescribed with antibiotics and analgesics after having performed a pharyngeal culture. Follow up was performed via telephone survey 24 and 48 hours after the clinical visit to measure subjective complaints of pain. The degre of pain was measured by the VAS (visual analogue system). Results:The 3 groups scored an average of 3.23, 4.14 and 5.90, respectively, on the VAS scale after 24 hours of visit. After 48 hours the 3 groups scored 2.00, 1.65 and 3.03, respectively. From these results, VAS score was significantlyin the group of oral steroid prescription, regardles of NSAIDS use, and this pattern increased in cases where bacterial cultures showed positive. However, there were no significant differences in the duration of illness, oral intake and limitation of activity among the 3 groups. Conclusion:The use of short term oral steroids for the treatment of acute pharyngitis can help to decrease the intensity and duration of pain, and this tendency seems to increase in cases where bacterial cultures show positive results.

Background and Objectives:Various phonation patterns yield various voice characteristics. Voice therapy using nasal stimulatory sounds seems to facilitate phonation in voice disodered patients. Under the hypothesis that nasalance may be influenced by the pattern of phonation, we studied the relationship between nasalance and voice disorders by observing abnormal supraglottic movements and vocol cord gaps in phonation. Subjects and Method:There were 143 patients who complained of voice problems and showed abnormal false vocal cord movements under stroboscopy. In addition to the four previously described types of MTD (muscle tension dysphonia), we described two more types of MTD (V:false vocal cord contracted posteriorly, VI:false vocal cord dilated laterally). We measured the vocal cord gaps in phonation and analyzed nasalance. Results:Among those groups showing the pattern of false vocal cord (MTD 1, 2, 4), the vocal cord gaps in phonation were increased and nasalance was significantly decreased in MTD types, III and IV, and showed a tendency to decrease in MTD types, II and V, compared to the normal group. Conclusion:The supraglottis has a tendency to contract as the vocal cord gap in phonation increases, and this movement reduces nasalance.

Foreign bodies in the oral cavity and pharyngolarynx are comonly encountered accidental cases in the emergency room and out patient departments in the otolaryngological fields. Of such foreign bodies, fish bones are the most comonly observed. ed by careful history taking, precise physical examination, and through simple radiological procedures. Similarly, their removal is relatively simple with the manipulation of endoscopes and various instruments. Reports of such foreign bodies are relatively fre-quent in their finding, however, foreign bodies that penetrate the esophagus and laryngopharynx to appear as a cervical mas are rare. When such foreign bodies migrate, locating their precise positions must involve a more thorough search utilizing such aids f this study experienced such a rare case of an elderly female patient aged 62, presenting an anterior neck mass of 7 days as a chief complaint. She had swallowed a fish bone 10 days ago. Her standard batery of blod tests, simple cervical X-ray and endoscopic findings all proved within normal limits. However, an excisional biopsy of the involved site revealed a piece of fish bone that had th the relevant literature. (Korean J Otolaryngol 203 ;46 :255-8)
