Even though it is generalized to perform synchronous lip and nasal correction, there are some cases in need of secondary correction of cleft lip nose deformity. In these procedures, the lengthening of columella plays an important role. We performed eighteen cases of the secondary cleft lip nose deformity correction using two different methods from 1997 to 2003. The central lip flap was used in eight patients and V-Y advancement flap in ten patients. Additional procedures including reverse U-incision, interdomal fixation sutures and suspension sutures were used for correction of combined deformity. Silastic nasal retainers were kept in all patients for 6 months. Both of central lip flap and V-Y advancement flap seems to be a good technique for lengthening columellar soft tissue. But new columella after V-Y advancement flap appeared to be too narrow and a bit unnatural looking and central lip flap left additional scar on the upper lip although it was conspicuous. We think that central lip flap is a better technique in a case with wide philtrum and narrow columella and V-Y advancement flap can be another choice in a columella with sufficient width.

Objective : Traditionally, peritoneal catheter is inserted with midline laparotomy incision in ventriculoperitoneal (V-P) shunt procedures. Complications of V-P shunt is not uncommon and have been reported to occur in 5-37% of cases. The aim of this study is to compare the clinical outcomes and the operation time between laparotomy and laparoscopic groups. Methods : A total of 155 V-P shunt procedures were performed to treat hydrocephalic patients of various origins in our institute between June 2006 to January 2010; 95 of which were laparoscopically guided and 65 were not. We reviewed the operation time, surgery-related complications, and intraoperative and postoperative problems. Results : In the laparoscopy group, the mean duration of the procedure (52 minutes) was significantly shorter (p < 0.001) than the laparotomy group (109 minutes). There were two cases of malfunctions and one incidence of diaphragm injury in the laparotomy group. In contrast, there were neither malfunction nor any internal organ injuries in the laparoscopy group (p = 0.034). There were total of two cases of infections from both groups (p = 0.7). Conclusion : Laparoscopically guided insertions of distal shunt catheter is considered a fast and safe method in contrast to the laparotomy technique. This method allows the exact localization of the peritoneal catheter and a confirmation of its patency.

Objective : The percutaneous thread transection technique is a surgical dissecting method using a dissecting thread inserted through a needle under ultrasound guidance without skin incision. As the new dissecting threads were developed domestically, this cadaver study was conducted to compare the effectiveness and safety between the new threads (ultra V sswire and smartwire-01) and a pre-existing commercial dissecting thread (loop & shear) by demonstrating a modified looped thread cubital tunnel release. Methods : The percutaneous cubital tunnel release procedure was performed on 29 fresh cadaveric upper extremities. The pre-existing commercial thread was used in 5 upper extremities. The two newly developed threads were used in 24 upper extremities. Two practitioners performed the procedures separately. After the modified looped thread cubital release, anatomical and histological analyses were performed by a blinded anatomist. The presence of the dissected cubital tunnel and damaged adjacent soft tissue was assessed. Results : Out of the 29 cadaveric upper extremities, 27 specimens showed complete dissection of the Osborne ligament and the proximal fascia of the flexor carpi ulnaris muscle. One specimen was incompletely dissected in each of the ultra V sswire and smartwire-01 groups. There were no injuries of adjacent structures including the ulnar nerve, ulnar artery, medial antebrachial cutaneous nerve, or flexor tendon with either the commercial thread or the newly developed threads. The anatomical analysis revealed clear and sharp incisional margins of the cubital tunnel in the Smartwire-01 and loop & shear groups. All three kinds of threads maintained proper linear elasticity for easy handling during the procedure. The smartwire-01 provided higher visibility in ultrasound than the other threads. Conclusion : The newly developed threads were effective and safe for use in the thread cubital tunnel release procedure.

Background: To date, a variety of surgical approaches have been used to reconstruct the medial orbital wall fracture. Still however, there is still a controversy as to their applicability because of postoperative scars, injury of anatomical structures and limited visual fields. The purpose of this study was to introduce a useful additional medial subbrow approach for better reduction and securement more accurate implant pocket of medial orbital wall fracture with the subciliary technique. Methods: We had performed our technique for a total of 14 patients with medial orbital wall fracture at our medical institution between January 2016 and July 2017. All fractures were operated through subciliary technique combined with the additional medial subbrow approach. They underwent subciliary approach accompanied by medial wall dissection using a Louisville elevator through the slit incision of the medial subbrow procedure. This facilitated visualization of the medial wall fracture site and helped to ensure a more accurate pocket for implant insertion. Results: Postoperative outcomes showed sufficient coverage without displacement. Twelve cases of preoperative diplopia improved to two cases of postoperative diplopia. More than 2 mm enophthalmos was 14 cases preoperatively, improving to 0 case postoperatively. Without damage such as major vessels or extraocular muscles, enophthalmos was corrected and there was no restriction of eyeball motion. Conclusion: Our ancillary procedure was useful in dissecting the medial wall, and it was a safe method as to cause no significant complications in our clinical series. Also, there is an only nonvisible postoperative scar. Therefore, it is a recommendable surgical modality for medial orbital wall fracture.

After Tennison introduced a triangular flap method which, for the first time, preserved the Cupid's bow, Randall gave this method a sound mathematical basis. This method is also called as an inferior triangular cheiloplasty which is characterized by making a small triangular flap from the lateral border of cleft destined to be fitted into an incision on the medial side of cleft. He postulated that the height obtained was equal to the sum of the median of the two triangles used in the cheiloplasty. Using this technique, a 22 month-old male patient with incomplete unilateral cleft lip was corrected primarily. The deviation of the columella and flattening of the nostril on the cleft side were minimal. The operation was done under general anesthesia and patient was healed uneventfully. We tried to improve the symmetry and esthetic feature of philtrum, nostril sill, alar-facial groove, preventing the notch formation on the nostril floor, and to reconstruct the muscle sling in the upper part of lip. The shape of Cupid's bow was restored, and the symmetry of columella was regained as a result. In summary, the inferior triangular cheiloplasty is effective to correct the primary unilateral cleft lip, results in the restoration of favorable anatomy and function.

Purpose: Constricted ear, which is named by Tanzer includes lop ear, cup ear, and sort of prominent ear. It has classified three groups by Tanzer, especially grou I and IIA have been corrected by banner flap, Musgrave's technique, tumbling concha - cartilage flap, reversed banner flap and others. However, these techniques were too invasive for correcting mild degree of deformity. Therefore, we corrected the ear with mattress suture which is simple and less invasive. Method: The operations were done against 5 patients from 2005 March to 2008 April. All the cases were unilateral ears with constriction included helix and scaphoid fossa without difference in length between both ears. Though a posterior auricular skin incision, the folded cartilage is exposed and two parallel incisions on superior crus were made. After mattress suturing in cartilage, the superior crus of antihelix was formed and its force enables the folded portion to be in a normal anatomic position. Result: All of 5 patients got satisfactory results. There were no complications like hematoma or skin necrosis, and no recurrence during follow - up period(the average period was 9 months). And we couldn't recognize the difference between height of both auricles. Conclusion: Mattress suture is simple, less invasive, and suitable on correcting mild deformity of constricted ear with better result, so here we suggest the method.

우리는 3예의 편측성 불완전 구순열 환아에서 Bardach 삼각피판법을 사용하여 구순열을 수복하였다. Millard법에 비해 비주기저부와 비익기저부에 부가적인 절개를 가하지 않으므로 술후 반흔을 줄일 수 있었다. 또한 Tennison-Randall법에 비해 간단하면서도 정교한 계측에 의한 작도가 가능하였다. 한편 삼각피판법의 단점으로 지적되고 있는 인중 부위의 술후 반흔은 3예 모두 불완전 구순열이었기 때문에 삼각피판의 길이가 짧아 심미적으로 허용할 만하였다. Bardach 삼각피판법은 편측성 불완전 구순열의 수복에 추천할 만한 술식임을 경험하였다.

Objective : Transseptal or sublabial transsphenoidal surgery has been standard teatment for pituitary tumors for decades. However, as an alternative to this surgery endonasal endoscopic technique has been reported with encouraging results. We have started endoscopy-assisted transsphednoidal surgery from May 1998. In this paper we analyzed the methods, outcome, advantage and disadvantage of this surgical approach for the purpose of planning optimal treatment of pituitary tumors. Methods : This study consisits of 13 cases of pituitary tumors who were treated by endoscopy-assisted transsphenoidal surgery using one nostril from May 1998 to July 1999. Mean follow up period was 12.9 months. Results : There was no septal or sublabial incision and little surgical damage to nasal structure. With this technique, rapid surgical approach and short hospital day were possible, being 3-6 days in patients without CSF leakage. Using various angled endoscope, good surgical view was obtained. Initially it was difficult to use various instruments in narrow nasal cavity, but became feasible after several procedures. Among 13 cases, total removal was possible in 11 cases. One of two cases in whom tumor was incompletely removed underwent gamma-knife radiosurgery and second underwent reoperation through subfrontal approach. There were 6 cases of hormone secreting tumors and hormonal remission was achived in all of these cases. Postoperative complications were CSF leakage(6 cases), diabetes insipidus(2 cases) and panhypopituitarysm(1 case). Lumbar drainage was done in all cases of CSF leakage. Conclusion : The advantage of endoscopy-assisted transsphenoidal surgery are rapid surgical approach, low postoperative morbidity, short hospital day and good surgical view. The disadvantage of this appoach are difficulty in manupulating various instruments in narrow nostril and difficulty in distance perception but these problems can be overcome by practice and using stereoscopic endoscope.
