Purpose: The congenital muscular torticollis is a neck deformity involving shortening of the sternocleidomastoid muscle, which is detected at birth or shortly after birth. This childhood disease is the third most common congenital musculoskeletal anomaly. The indication for surgery is a persistent head tilt with dificit of passive rotation and lateral bending of the neck and a tight band or tumor in the sternocleidomastoid muscle even after physical therapy. The purpose of this article is to report surgical outcomes with patients who had no or little response to physical therapy. Methods: Surgery was performed on 29 patients and their average age was 4.1 years (from 6 months to 20.1 years). The unipolar open release and partial myectomy were done in 28 cases and the muscle lengthening was done in 1 case. Physical therapy was started from postoperative seventh day. Follow - up period was ranged from 2 months to 5.4 years(mean follow - up, 20.4 months). Result: There were neither rotation nor lateral bending deficit after surgical treatment. Mild head tilt was noticed in 3 cases and residual bend was observed in 4 cases. The subjective assessments of surgical results by parents were excellent. Conclusion: Our surgical outcome encourages the surgical treatment of congenital muscular torticollis for patients who failed to respond to physical therapy.

Forty nine patients [M: 31, F: 18], age from 2 months to 17 years [mean= 4.9 years], underwent operations, from April 1986 to December 1992, for the relief of subvalvular aortic stenosis in normal atrioventricular and ventriculoarterial connections.There were 4 anatomic types of subaortic stenosis : membranous in 29 cases [59.2%], fibromuscular in 11 [22.4%], diffuse tunnel type in 7 [14.3%], and miscellaneous in 2 cases. Thirty four patients [69.4%] had associated cardiac anomalies, of which ventricular septal defect was the most common [27 cases]. Other anomalies were patent ductus arteriosus, coarctation of the aorta, valvular aortic stenosis, double chambered right ventricle [DCRV], infundibular pulmonic stenosis, persistent left superior vena cava, and rigt aortic arch. Mean systolic pressure gradient between the left ventricle and ascending aorta was 26.4$\pm$17.6 mmHg : 13.1$\pm$17.6mmHg in the membranous type, 22.0$\pm$18.4mmHg in the fibromucular type, and 56.1$\pm$38.4mmHg in the diffuse tunnel type. Operative procedures were determined according to the type of subvalvular aortic stenosis : simple excision of subaortic membrane in the membranous type [29 cases], left ventricular myectomy with or without myotomy or fibrous tissue excision in the fibromuscular type [11 cases]. Among the 7 of diffuse tunnel type cases, ventricular myectomy was performed in 2 and a modified Konno operation was performed in 5 . Postoperative follow up was made with periodic echocardiography. The Mean postoperative follow up period was 33.8 months. There were 2 hospital mortalities [4.1%] and 2 late deaths. Residual stenosis remained in 3 cases and recurrence developed in 2 cases during the follow up period. 5 years actuarial survival rate was 91.8$\pm$3.9% and 5 year complication free rate was 72.3$\pm$10.4%. Conclusions : 1. Subvalvular aortic stenosis should be relieved completely as soon as possible when diagnosed, regardless of left ventricular outflow tract pressure gradient. 2. Good results were obtained using only simple excision of subaortic membrane in the membranous type of subaortic stenosis. However, aortoventriculoplasty [modified Konno prodedure] was necessary for good results in the diffuse tunnel type. 3. Periodic postoperative echocardiography was helpful in detecting the progression of residual stenosis and development of new stenosis.

In candidates for aortic valve replacement [AVR]it is our primary intention to implant the largest possible vale prosthesis of at least 23 mm in diameter in patients with severe valvular aortic stenosis. However, in many patients there is an additional subvalvular asymmetric septal hypertrophy which in some cases may cause an postextrasystolic increase of the LV-aortic gradient. Another component of the aortic stenosis syndrome is a narrow valvular ring, or a combination of both. After complete removal of the diseased valve and decalcification the narrow aortic ring [< 23 mm] can be widened firstly by transaortic subvalvular septal myectomy- [TSM] thus unfolding the left ventricular outflow tract[LVOT]and secondly by extending the oblique aortic incision into the aortic valve ring or further down into the anterior leaflet of the mitral valve. The sub-and supra-valvular defect will be closed by patch enlargement of the aortic root [PEAR] using autologous pericardium. These techniques allow a considerable enlargement of the valvular ring of about 4 to 10 mm in circumference. In a retrospective study using a computerized program, 847 patients with AVR [1980-1984]were reviewed to evaluate the intraoperative hemodynamic results mainly concerning relief of the transvalvular gradient. In 626 patients AVR was performed, 151 patients had double valve replacement [AVR+MVR], and 70 patients had AVR plus additional surgical procedures. Concentrating on the AVR-group [n=626] there were 103 patients with TSM, 24 patients with PEAR and 20 patients with TSM+PEAR which demonstrated that in a total, of 147 patients of this groups [23.5%] an additional procedure was necessary. The Statistical evaluation of the intraoperative pressure measurements before and after AVR in relation to the size of the implanted prostheses indicated the lowest preoperative mean gradient in patients with AVR alone, the highest in patients who afforded TSM plus PEAR. However, after AVR the mean gradients in all three groups were very low [mean 5 to 10 mmHg]. These data indicate that in patients with a narrow aortic ring and additional considerable ASH, TSM and PEAR are suitable techniques to enlarge the aortic root to enable the implantation of an adequate aortic valve prosthesis. Long-term controls have shown that autologous pericardium is a qualified graft material for the ascending aorta.

Spasmodic dysphonia is a focal laryngeal dystonia that results in involuntary spasms during speech. The etiology of spasmodic dysphonia is not yet defined, but it is presumed to be a neurological abnormality of central nervous system motor function. The treatment of choice for spasmodic dysphonia is botulinum toxin injection directly at the laryngeal muscles. However botulinum toxin injection requires repeated procedures. Many different kinds of surgical treatments have been introduced but the recurrence rate is still high. So we performed myomectomy with LASER and neurectomy with specially designed electrical surgical knife which can cut recurrent laryngeal nerve branch selectively with its noble curved section. We report a case of a 43-year-old male patient with spasmodic dysphonia treated by thyroarytenoid myoneurectomy.

For 26 months since August 1991, 10 consecutive patients with congenital left ventricular outflow tract obstruction underwent corrective surgery in Pusan Paik Hospital. Their ages ranged from 2 to 18 years. There were 6 male and 4 female patients. According to stenotic site, obstruction were classified into supravalvular [n = 5], subvalvular [n = 4], valvular stenosis [n = 1]. We have performed patch enlargement of ascending aorta [n = 2], supravalvular membrane resection and patch enlargement of ascending aorta [n = 3], subvalvular membrane resection [n = 2], subvalvular membrane resection and left ventricular myectomy [n = 2] and aortic annuloplasty with Dacron patch and aortic valve replacement [n = 1]. Preoperative mean value of systolic pressure gradient were 85.0 $\pm$29.2mmHg[supravalvular], 70.0mmHg[valvular], 72.5 $\pm$ 22.5mmHg[subvalvular], and 78.5 $\pm$ 24.3mmHg[total]. Postoperative mean value of systolic pressure gradient were 31.0 $\pm$ 8.9mmHg[supravalvular], 0mmHg[valvular], 15.0 $\pm$ 10.8mmHg[subvalvular], and 21.5 $\pm$ 13.9mmHg[total]. Postoperative systolic pressure gradient was decreased significantly[p = 0.001]. Postoperative course and short-term follow up results were good except one case of transient heart failure.

배경: 분리 대동맥판막하 협착증은 수술 후에도 재발을 잘하는 것으로 알려져 있다 저자들은 수술 전후의 좌심실 유출로를 통한 압력차 및 재발률 등에 대하여 후향적 연구를 시행하였다 대상 및 방법: 1984년 9월부터 2004년 12월까지 34명의 환자가 분리 대동맥판막하 협착증으로 수술을 시행 받았다. 평균 나이는 $17.1\pm15.2$세였으며 19명$(55.9\%)$이 남자였다. 16명$(47.1\%)$의 환자가 이전에 심장수술을 받았다. 수술시 동반된 질환은 대동맥판막 폐쇄부전(11), 대동맥 축착증(3) 등이었다. 걸U: 수술직후의 좌심실 유출로를 통한 최대 압력차는 수술 전보다 유의하게 낮았고(75.8 mmHg vs 21.8mmHg, p<0.01), 평균 50.3개월 후에 측정된 치대 압력차도 20.2 mmHg로 수술 직후와 큰 차이 없이 여전히 수술 전보다 낮은 수치를 나타내었다. 수술 사망은 없었으며 1예에서 수술 후 합병증으로 뇌경색이 발생하였다. 평균 추적 관찰 기간은 $69.8\pm54.6$개월이었으며, 이 기간 중에 5명$(14.7\%)$이 재수술을 시행 받았고, 이 중 3명$(8.8\%)$의 환자는 분리 대동맥판막하 협착의 재발로 인해 재수술을 시행 받았다. 통계적으로 유의한, 재발에 대한 위험인자는 없었으며 10년에서의 무재수술 생존율은 $76.4\%$였다. 결론: 분리 대동맥판막하 협착증의 치료에 있어 대동맥판막하 막성 조직만을 제거하거나 혹은 주위 근육과 함께 절제하는 방법은 낮은 사망률과 합병증을 보였으며 수술 후 충분한 좌심실 유출로 최대압력차의 감소를 보였다. 그러나 재발을 잘하고 예측할만한 위험 인자가 없으므로 지속적인 추적 관찰이 필요하리라 생각한다.
