For the treatment of acute respiratory failure and emergency care of an urgent patient, tracheostomy in itself may have been a life saving procedure. But, tracheal stenosis gives serious clinical manifestation which can only be corrected by surgical intervention in many occasions. We experienced one case of tracheal stenosis following tracheostomy for assisted ventilation. Tracheogram showed a 4.0 cm segmental narrowing below the tracheostoma. Before reconstruction, we tried to T-tube cannulation, but the result was not satisfactory. So we resected the narrowed segment and tracheal reconstruction was performed with uneventful result.

Objective : Transsphenoidal approach(TSA) has been used as useful operative method for pituitary tumor but is still controversal in case of cavernous sinus invasion or severe suprasellar extension. This study was performed to evaluate the surgical result, recurrence, effect of adjuvant treatment, especially in cases of suprasellar extension or cavernous sinus invasion. Material and Methods : We studied 56 cases of surgically treated pituitary adenoma that we were able to follow up, treated by TSA from 1993 to 1998. There were 24 cases of suprasellar extension and 11 cases of cavernous sinus invasion. The medical records and radiological findings were reviewed. Surgical results including hormonal function and recurrence rates were analyzed according to extent of tumor invasion. Mean follow-up period was 19.1 months. Results : Tumors with suprasellar extension were removed totally in 54%, whereas total tumor removal was possible only in 38% with cavernous sinus invasion. Overall of recurrence rate was 14% and recurrence rate was 25% in suprasellar extension and 9% in cavernous sinus invasion. In cases of both suprasellar extension and cavernous sinus invasion, tumors that were treated by TSA and radiation showed recurrence rate of 7%, whereas those treated by surgery alone showed 28% of recurrence. Conclusion : Transsphenoidal approach is safe and useful operative method for pituitary adenoma and adjuvant therapy including radiation therapy is effective means to decrease the recurrence in cases of suprasellar extension or cavernous sinus invasion.

Objectives : This study will broaden understanding of acupotomy therapy through comparison of side effects and complication which can be caused by the mechanism of treatment, surgical methods, and procedure by acupotomy therapy and epidural neuroplasty. Moreover, through an in-depth analysis of headache affected by two procedures, this research is supposed to find prospective cures for headache after acupotomy therapy. Methods : To compare acupotomy therapy with epidural neuroplasty this research was done using a comparative analysis eight theses about acupotomy therapy since 1995, as well as eleven theses about epidural neuroplasty since 2000. Other theses and data were used as references in the process of comparative analysis. Results : Acupotomy therapy and epidural neuroplasty, new treatments of damaged discs in the spine and stenosis made in 1990s, have the mechanism of treatment in common in that adhesion, a node or scar caused by the soft tissue damage is removed by putting catheter or acupuncture into the lesions. Epidural neuroplasty has additional injection into the lesions, which is different from acupotomy therapy in the process of surgical procedure. There are various reports of positive effects about curative effect in these two treatments. The two procedures may cause various complications. Headache may be a complication after surgery. The headache after acupotomy therapy is characterized as being an ache in the body, which is similar to that of post-dural puncture headache in the outbreaks and symptom. Headache after percutaneous epidural neuroplasty appears in general, which is similar to a headache as a result of the increased pressure of the brain spinal cord regardless of posture. Conclusions : Although they are alike in the mechanism of treatment, surgical methods and side effects, and complication after they are carried out as a result of analyzing theses related to acupotomy therapy and percutaneous epidural neuroplasty, there is a difference in aspects and mechanism of headaches experienced after the procedure.

Arthrosis of the temporomandibular joint is defined as a disease of a joint with chief complaint of pain, clicking, limited jaw movements. Generally, most patients with the temporomandibular arthrosis can be treated conservatively with muscle relaxation therapy combined with mandibular repositioning prostheses, followed by occlusal equilibration, restorative dentistry and/or orthodontics, and many other forms of treatment. In case prior nonsurgical treatment proved to be ineffective or the disease is chronic and severe, surgical operation is recommended. For patients with arthrosis of the temporomandibular joint, only discectomy as therapeutic method of the surgical treatment should not be applied and the removed articular disc of the temporomandibular joint should be replaced. Allograft such as Proplast-Teflon, Silastic, etc have been used as replacements of removed articular disc. However, these allograft materials have caused complications such as inflammatory changes, foreign body reactions. As a result, a replacement material which is autogenous, space occupying, easy to harvest and less inflammatory change has been developed. Auricular cartilage with perichondrium satisfies many of these requirements. The apparent advantages of autogenous auricular cartilage as an interpositional graft after a discectomy are as follows, (1) the form of the external ear corresponds to joint morphology, (2) a graft of adequate size can be harvested, (3) the form of the external ear remains unchanged after surgery, (4) the graft can be obtained adjacent to the surgical site, (5) biologically acceptable material is used, (6) the additional expense of allogenic graft is avoided. Because we considered autogenous auricular cartilage as a good replacement material, removed articular disc has been replaced with fresh autogenous auricular cartilage in the case of three patients. The result of the treatment is favorable, and the cases being presented here.

Objective : The introduction of MRI makes it easy to detect multiple lumbar disc herniation. However, MRI is not a physiologic test for detecting the symptomatic level. For the surgical plan, it is very important to determine the symtomatic level among the multiple lumbar disc herniation. In this regard, we studied diagnostic significance of discography on multiple lumbar disc herniation in determining the symptomatic level. Method and Material : We retrospectvely analyzed the discographic and clinical findings of 121 patients with multiple lumbar disc herniation for investigating the diagnostic availability of discography. All were surgically treated from January 1995 through May 1998. Result : Discography provocated the same pain as usual symptom in 99 out of 121 patients(81.8%). Compared with surgical findings, the diagnostic accuracy of the discography in multiple lumbar disc herniation was 75.6%, sensitivity was 64.6%, and specificity 87.2%. There was no correlation between the pain provocation of discography and the extent of annular degeneration on CT/discogram. The pain provocation showed good correlation with the extent of annular disruption on CT/discogram. The rate of same result(correlation rate) between the discography and D.I.T.I was 81.4% in multiple lumbar disc herniation patients with unilateral leg pain. Conclusion : These results indicate that in multiple lumbar disc herniation, the discography is considered useful diagnostic tool to determine the symptomatic level and to decide the surgical plan.

Objective: The surgical approach for anterior choroidal artery (AChA) aneurysm is typically similar to those used for other supraclinoid internal carotid artery (ICA) lesions. However, the surgical clipping of this aneurysm is complicated and as a result. can result in postoperative ischemic complications. The purpose of this study was to clarify the risk of clip-induced ischemic complication in AChA aneurysm and to get the benefits for helping decision making. Methods: We retrospectively investigated 53 cases (4.0%) of AchA aneurysm treated surgically. We divided the AChA aneurysm to 3 subtype according to the origin of aneurysmal neck; A type originating from the AChA itself. J type from junction of AChA and ICA and I type from the ICA itself. We evaluated brain CT about 1 week post-operative day to confirm the low density in AChA territory. Results: Ruptured aneurysm was 26 cases and unruptured aneurysm 27 cases. The aneurysmal subtype of A, J, and I was 13, 17, and 23 cases. Of the 53 cases who performed surgical neck clipping, twelve (22.6%) had postoperative AChA distribution infarcts. Increased infarct after neck clipping had statistic significance in non-I subtype (r=0.005) Conclusion: AChA aneurysm surgery carries a significant risk of postoperative stroke. Don't always stick to clipping only, especially in non-I type of incidental small aneurysm, which has high risk of post-clip ischemic complications.

Background : The surgical removal of impacted mandibular third molar can result in considerable pain, swelling, and dysfunction that patient are incapable of work for several days. Factors contributing to post operative swelling, trismus and pain are complex. There is no question but that the procedure of surgically removing an impacted mandibular third molar is inherently a traumatic one and that some sequelae related to the inflammation response are expected. Meticulous surgical technique will minimize the sequelae of inflammation but will not prevent them. In an effort to minimize these sequelae the use of steroid was instituted. Patients and Methods : Present study was to investigate the effect of one preoperative steroid injection in the masseter muscle to the patients(male 9, female 11) who needed prophylactic removal of bilateral, symmetrical, impacted wisdom teeth in the mandible on the complaint like swelling, trismus and pain. through Double-Blind test. Results : 1. After 24 hours investigation, preoperative steroid injection had significantly reduced swelling with 39% and trismus with 57.5%. 2. $7^{th}$ post operative day investigation, reduced swelling and trismus had shown, however, not significant. 3. There wasn't major difference from the group who took preve-ntive steroid in the visual analogue scale, the first analgesic intake time and the pain period. 4. There wasn't any adverse reaction of steroid for 20 patient From the above result, If the patients are not contraindication to steroid and pronounced post operative reaction can be expected the use of steroid to the surgical removal of impacted mandibular third molar is recommended.

Purpose: Currently the substantial clinical benefits of single-port laparoscopic appendectomy (SLA) over conventional three-port laparoscopic appendectomy (CLA) are equivocal. The aim of this study was to compare surgical outcomes between SLA and CLA in children with acute appendicitis. Methods: A single blind prospective randomized single center study was performed to compare the surgical outcomes of SLA and CLA. A total of 105 patients were randomized and various parameters were analyzed, 52 patients with SLA and 53 patients with CLA between July 2013 and March 2014. Patients with sonographically confirmed acute appendicitis were randomly assigned to receive either SLA or CLA. The outcome measurements were operating time, wound complication, and intraperitoneal morbidities, postoperative pain score and cosmetic result score. Results: Operating time is significantly longer in SLA ($70.4{\pm}26.7$ minutes vs. $58.0{\pm}23.4$ minutes; p=0.016). There were no significant differences in the postoperative wound complication rate and intraperitoneal morbidities between two groups. There were no significant differences in postoperative resting pain score ($6.6{\pm}2.5$ vs. $6.3{\pm}2.5$; p=0.317) and activity pain score ($6.9{\pm}2.4$ vs. $6.3{\pm}2.5$; p=0.189), and the cosmetic result score ($9.2{\pm}1.1$ vs. $9.1{\pm}1.4$; p=0.853). Conclusion: Although SLA would be a safe and feasible procedure in children, SLA could not demonstrate the clear benefit over CLA.
