Carpal tunnel syndrome is the most common peripheral nerve entrapment syndrome due to compression of the median nerve at the wrist. Division of the transverse carpal ligament for median nerve compression in patients with carpal tunnel syndrome is a common and successful procedure. A variety procedures exist to release the transverse carpal ligament the classic open release, limmited open or percutaneous release, and endoscopic release. From February 1994 to January 1996, 39 carpal tunnel releases were performed by percutaneous method in 30 patients (3 males and 27 females) at the Chonnam University Hospital. The patients age ranged from 42 to 67 years (average 54.8 years). The duration of the symptoms ranged from 3 months to 10 years. According to Brown's outcome analysis, results were as follows. 1. Persistent pain and paresthesia were noted in only 3 cases (7.7%) at 24 week postoperatively. 2. Two-Point discrimination on the index finger was improved significantly at 12 week postoperatively (p<0.05). In electromyographic study, conduction delay of motor and sensory fibers was diminished significantly at 4 week postoperatively (p<0.05). 3. Functional outcomes (grip strength, pinch strength, scar tenderness and return to work) were showed good and excellent result. We concluded that percutaneous decompression is one of the less morbid method for decompressing the carpal canal and relief of symptoms for the patient.

Many allograft materials have been used for performing augmentation rhinoplasty. But in cases involving complications such as infection, inflammation and foreign body reaction, these should be removed and replaced with an autograft material which is more suitable for revision surgery. Frequently, the use of autograft materials, including bone and cartilage, are restricted by many limitations such as unavailability, insufficiency in volume, and resorption. By using the dermofat, however, we achieved good surgical results in revision rhinoplasty from the aspect of volume and donor site morbidity. Thus, we report this case with a review of the literature.

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.

PURPOSE: To evaluate MRI findings of malignant ovarian tumors. MATERIALS AND METHODS: MRI findings were retrospectively reviewed in 25 patients with surgically confirmed 30 malignant ovarian tumors(common epithelial tumor;23, sex cord stromal tumor;2, endodermal sinus tumor ; 1, metastatic tumor ;4). The findings evaluated were the lesion size, solid and/or cystic component, wall thickness, septal thickness, necrosis, invasion of adjacent organ, ascites, and adenopathy. RESULTS: MRI findings of the malignant ovarian tumors were as follow:Size of lesion was 5-35cm(mean 14cm) ;solid component was present in 80%(24/30);wall thickness was more than 3ram in 90%(27/30);septal thickness was more than 3ram in 70%(21/30);tumor necrosis was present in 40%(12/30%) ;invasion of adjacent organ was present in 76%(19/25);ascites was present in 56%(14/25);lymphadenopathy was present in 24% (6/25). MRI findings of absence of solid component(6/6), even wall and septal thickness(7/7, 19/19) were found only in epithelial tumors. Uneven septal thickness more than 3mm(7/11) was a predominant MRI findings of non-epithelial tumors. Well-defined cystic lesion within solid component was seen in Krukenberg tumors. CONCLUSION: Evaluation of the lesion size, internal architecture, invasion of adjacent organ, ascites, and lymphadenopathy in MRI would enable diagnosis of malignant ovarian tumors and could lead to possible differential diagnosis of epithelial tumors from non-epithelial tumors.
