The midcarpal joint has inherent instability in the sagittal plane. Several instability patterns of midcarpal joint due to ligament insufficiency have been presented. We ohserved the normal midcarpal and radiocarpal behaviors of ligament laxity in the sagittal plane to investigate the significance of dorsal and palmar stress test which has been used for evaluation of the non-dissociative carpal instahilities. We performed the dorsal and palmar displacement stress test on fifty pairs of normal wrist joints under the flouroscopic views. The midcarpal joints were subluxed, more on dorsal stress, with variable degrees. Dorsal subluxations in females and third decades were more prominent than males and fourth decades. Three types of radiocarpal instability on dorsal stress test could be observed. We think that displacement stress test in the sagittal plane should be interpreted in consideration of normal instability patterns in the evaluation of ahnormal midcarpal and radiocarpal instabilities since there are variable patterns and degrees of ligament laxity in normal wrist joints.

PURPOSE: Autologous platelet rich plasma (PRP) has been known to enhance tendon healing and improve tensile strength after tendon injury. This study investigated the dosage of PRP to increase the tensile strength. METHODS: PRP was harvested from peripheral bloods of the rabbits. Direct injury model was adopted using 60 achilles tendons in 30 rabbits. The autologous PRP was infiltrated into the Achilles tendon repair site of four groups (control, 0.1, 0.2, 0.4 mL) with different dosages. Tendons were harvested at 2, 4 and 8 weeks and subjected to measuring mechanical tensile strength and dosage of collagen content. RESULTS: At 2, 4, and 8 weeks, PRP administration following experimental achilles tendon repair resulted in an overall higher average tensile strength and collagen content compared to these of the control. Also, the lengthen the time, tensile strength and collagen content was increased. CONCLUSION: Autologous PRP enhanced tendon healing in rabbits. Within the PRP dosage setted by the author, more dosage of the infiltrated PRP increases the strength of the tendon and the dosage of collagen content. Further studies will be essential to determine the optimal dosage of PRP in clinical practice.

Behçet's disease is a systemic chronic disease that occurs in tissues such as eyes, joints, organs and nerves, and it has been noted that symptoms may be observed in a variety of tissues. In previous studies, reports of blepharoptosis observed in patients with Behçet's disease have been rare. We would like to report a case where a patient among those who visited our hospital with blepharoptosis had a history of Behçet's disease. This patient had been diagnosed with Behçet's disease, and complained of bilateral blepharoptosis even at the time of diagnosis. He complained of dysfunctions in vision and hearing, and upon eye examination, an eye movement disorder was found in his left eye. From the symptoms, neuro-Behçet's disease was diagnosed. The oculomotor and levator palpebrae superioris muscles are both controlled by cranial nerve III, which may suggest that Behçet's disease in this patient occurred in cranial nerve III. The patient received an oral steroid, and the symptoms have improved without surgery. Since we could identify the correlation between Behçet's disease and blepharoptosis, we considered that sharing this case and its outcome would be helpful for plastic surgeons who treat eyelids.

Despite the fact that benign skin lesions can undergo malignant transformation, the necessity and timing of the surgical resection have yet to be established. In this study, we analyse three cases of benign-appearing skin lesions, which were found to be carcinomatous on histologic examination and review the literature regarding the importance of prophylactic removal of benign-appearing skin lesion. The first and second cases were female patients wishing for cosmetic surgery. The first patient had a benign-appearing lesion on dorsum nasi, and the second patient had an inconspicuous lesion right along the right nasolabial fold. The third patient was a middle-aged male with a pigmented lesion on the left cheek, who presented to the clinic only after having met the operating surgeon through an acquaintance outside the hospital setting. All of the lesions were suspected to be of benign nature and were excised for cosmesis only. However, histologic examination of these lesions showed that the first two tumors were basal cell carcinoma with the last tumor being squamouse cell carcinoma. Thus, it is considered that removal of benign like skin lesion will result in good prognosis of patients scheduled to undergo other surgery.

We report two cases of cleidocranial dysplasia, which was managed without significant craniofacial osteotomy. A mother and daughter, both of normal intelligence, presented with central forehead depression, mid-face hypoplasia, and blepharoptosis. The fact that they have an identically deformed face implied a genetic basis. In both patients, radiologic evaluation revealed the underdeveloped maxilla, persistent fontanelle opening, and cleidal aplasia. Clinical findings and radiologic studies were consistent with the diagnosis of cleidocranial dysplasia. Both patients underwent forehead plasty via bicoronal approach, augmentation rhinoplasty using tip plasty, and epicanthoplasty. In addition, the mother underwent malar augmentation using Medpor implantation and reduction genioplasty. The patients did not experience any postoperative complication and remained satisfied with the operation at 6-year follow-up.

BACKGROUND: The nasal septal cartilage is often used as a donor graft in rhinoplasty operations but can vary widely in size across the patient population. As such, preoperative estimation of the cartilaginous area is important for patient counseling as well as operating planning. We aim to estimate septal cartilage area by using facial computed tomography (CT) studies. METHODS: The study was performed using facial CT images taken from 200 patients between January 2012 to July 2015. Using the mid-sagittal image, the boundary of cartilaginous septum was delineated from soft tissue using the mean difference in signal intensity (or brightness). The area within this boundary was calculated. The calculated area for septal cartilage was then compared across age groups and sexes. RESULTS: Overall, the mean area of nasal septal cartilage was 8.18 cm² with the maximum of 12.42 cm² and the minimum of 4.89 cm². The cartilage areas were measured to be larger in men than in women (p<0.05). The area decreased with advancing age (p<0.05). CONCLUSION: Measuring the size of septal cartilage using brightness difference is more precise and reliable than previously reported methods. This method can be utilized as the standard for prevention of postoperative complication.

The Parasitological investigation on the encysted metacercariae in brackish water fish, Tribolodon taczanowskii, in the downstream of Hyungsan river which is located in Kyungpook Province of Korea, were carried out serially and the following results were obtained. Metacercariae of Pseudexorchis major were found in six fishes(15.8 per cent ) out of 38 examined. Parasitic frequencies of the encysted metacercaria of Psedexorchis major in Tribolodon taczanowskii were 15.8 per cent (6 out of 38) in the scale, 10.5 per cent (4 out of 38) in the fin, 13.2 per cent (5 out of 38) in the gill, 10.5 per cent (4 out of 38) in the oral cavity and 7.9 per cent (3 out of 38) in the flesh. The worms were identified as Pseudexorchis major (Hasegawa, 1935) Yamaguti, 1938 by morphological studies on the metacercariae, excysted metacercariae, adults and eggs, and compared with prereported Pseudexorchis species.

In analyzing the postoperative results or evaluating the velopharyngeal incompetence after palatoplasty, speech evaluation is the inevitable factor. However, a standardized method for evaluating the speech problem in Korean cleft palate patients has not been available until now. So, the authors tried to establish a method of speech evaluation which is simple, economic and applicable to young patients, and to make a scoring method of the speech results in cleft palate patients based on the 'hypernasality diagnosing tool for cleft palate patient (OK Ran Jung)' which is commonly used by domestic speech therapists. The authors adopted the 'hypernasality diagnosing tool for cleft palate patients (OK Ran Jung)' male and female of children and adults, each consisting of 10 patients and make them speak according to the items about hypernasality and misarticulation evaluation, and record the results. We also calcuted the degree of the formants of the vowels (/a/, /o/, /u/)using sound spectrography. We examined the interjudge and intrajudge reliance of speech evaluation among the 10 inverstigators, revised the evaluation tool, devised the scoring method according to the above results, and compared the scoring results with those of sound spectrography to prove the reliance of our speech evaluation tool. With the scoring method, the authors could estimate the degree of hypemasality and misarticulation in cleft palate patients with evidence of reliability based on point-to-point agreement in two items. In comparing the results of our scoring method with the formant of vowels using sound spectrography, staistical significance existed except /u/F2 and that meant that our scoring method was reliable. We suggest that this simple, economic and reliable method of speech evaluation in cleft palate patients can create the basis for speech evaluation in patients of cleft palate and velopharyngeal incompetence under circumstances in which the results of various speech treatments are evaluated in comparison to various methods of speech evaluation.

Many methods of correcting secondary cleft lip nose deformity have been introduced, but a single best method that can be uniformly adjusted for all cases does not exist. Since it is difficult to make the nostril of the cleft side symmetric with that of normal side, the authors tried to formulate the basis for correction of unilateral secondary cleft lip nose deformity according to the varying amounts of deformed nostril. We then adopted 4 different methods of correcting the soft tissue and nostril deformity in 63 patients from 1996 to 1998 and surveyed the results. Our principles were as follows: 1) Alar rim incision was done in cases of different-shaped cleft-side nostrils with nearly the same measured area in comparison to the normal side. 2) When deformity of the alar-columellar web was severe, we performed modified Z-plasty. 3) When the nostril of the cleft-side nostril was smaller than the normal side with slight asymmetry, reverse W-plasty was done. 4) We adopted a reverse-U incision when there was a discrepancy in height with moderate asymmetry compared with the normal nostril. After dissection, repositioning of alar cartilage was done by same method in each case. A nasal stent was kept in position for at least 6 months postoperatively in almost all cases. After follow-up of 6 to 24 months, we concluded that our choice was correct in selecting the optimal operative method, considering the characteristics of deformity of the cleft side nostril in an effort to make it symmetric with that of the normal side.
