비인강폐쇄는 연구개, 인두측벽 그리고 인두후벽간의 움직임이 서로 조화되어 구강과 비강을 나누어주는 괄약근 기전으로서 연하, 호흡 및 발음 등의 생리적 기능에 중요한 역할을 한다. 이 기능에 문제가 생긴 경우를 비인강폐쇄부전이라하며 그 원인으로는 (1) 연구개의 길이 및 움직임이상, (2) 비인두강의 해부학적 공간문제, (3) 인두 후벽과 측벽의 기능이상 등이 있다. 본 연구는 구개월 환자의 측면두부방사선 사진을 통해 비인두강을 해부학적으로 분석하고 동시에 산출된 각 모음의 과비음 정도를 평가하여 비인강폐쇄부전과의 연관성을 비교해 본 것이며, 얻어진 결과는 다음과 같다. 1.연구개 길이는 정상인에 비해 현저히 짧았다. 2.adequate ratio는 정상인에 비해 작게 나타났다. 3.adequate ratio가 감소함에 따라 모음 조음시 anatomic mVPI가 점차 증가하였다. 4.각 모음 조음시 anatomic VPI는 과비음정도와 비례관계를 보였다. 5.고모음(/u/,/i/)의 과비음정도가 저모음(/a/)에 비하여 크게 나타났다. 결론적으로, 구개열환자에서 측면두부방사선 사진은 비인강폐쇄부전의 진단 및 평가에 유용하게 사용될 수 있으며, 비인두강의 해부학적 구조는 산출되는 과비음정도와 밀접한 연관성이 있었다. Nasopharyngeal closure is a sphincter mechanism between the activities of the soft palate, lateral pharyngeal wall and the posterior pharyngeal wall, which divides the oral cavity and the nasal cavity. It participates in physiological activities such as swallowing, breathing and pronunciation. In case of an error in this mechanism, it is called a nasopharyngeal incompetence. The causes of this error are defects in (1) length, function, posture of the soft palate, (2) depth and width of the nasopharynx, (3) activity of the posterior and lateral pharyngeal wall. The purpose of this study is to analyze the nasopharynz of cleft palate patients using lateral cephalograms and at the same time, evaluate the degree of hypernasality of each vowels to find its relationship with nasopharyngeal incompetence. The following results were obtained : 1.The length of the soft palate was markedly short than normal. 2.The adequate ratio was smaller than the normal value. 3.As the adequate ratio decreased, when articulating vowels, anatomic mVPI increased. 4.When articulating each vowels, anatomic VPI was in proportion with the degree of hypernasality. 5.The degree of hypernasality was greater in high vowels(/i/, /u/) than low vowel(/a/). From the above results, it can be concluded that in cleft palate patients, lateral cephalograms can be used effectively in diagnosing and evaluating nasopharyngeal incompetence. The anatomic structure of the nasopharynx has close relation to the degree of hypernasality.

Intracranial dural arteriovenous fistulas (DAVFs) are abnormal arteriovenous connections that lie within the dura. Intraosseous DAVFs involving diploic venous system are extremely rare. A 46-year-old woman presented with headache and right pulsatile tinnitus for three weeks. The tinnitus started after yelling. Digital subtraction angiography revealed DAVF within the basal portion of right parietal bone along the middle meningeal artery (MMA) groove. The fistula was fed by frontal branch of right MMA and drained into right transverse sigmoid sinus junction through dilated middle meningeal vein. The intraosseous DAVF involving diploic vein was successfully obliterated with Onyx embolization via transarterial route.

Although many patients with infective endocarditis (IE) complain of joint, muscle, and back pain, infections at these sights are rare. The incidence of spinal abscess in cervical spine complicating endocarditis is very rare. Although the surgical management is the mainstay of treatment, conservative treatment can get success in selected patients. We report a patient with cervical epidural abscess due to Streptococcus viridans endocarditis. Both epidural abscess and IE were managed conservatively with intravenous antibiotics for 8 weeks, with recovery. It is important to remind spinal epidural abscess can occur in those patients with bacterial endocarditis.

Dural arteriovenous fistula (DAVF) is a rare condition affecting approximately 1.5% of 1,000,000 individuals annually. It frequently occurs in the transsigmoid and cavernous sinuses. An isolated sigmoid sinus is extremely rare and is treated by performing transfemoral transvenous embolization along the opposite transverse sinus.A 69-year-old woman presented with asymptomatic Borden type III/Cognard type III DAVF involving an isolated sigmoid sinus. She underwent a staged operation in which a navigation system was used to expose the sigmoid sinus in the operating room before transferring the patient to the angio suite for transvenous embolization.Various modalities have been used to treat DAVF, including surgical disconnection, transarterial embolization, transvenous embolization, and stereotactic radiosurgery. However, treating DAVF cases where the affected sinus is isolated can be challenging because an easily accessible surgical route may not be available. In this case, direct sinus cannulation and transvenous embolization were the most effective treatments.
