  • Angiomyoma is a rare, benign smooth muscle cell tumor. These tumors may be found anywhere in the body. They frequently occur in the lower extremities except venous type. Angiomyoma in the head and neck area is very rare, and only a few cases have been reported. A 63 year-old male patient visited to outpatient clinic due to size-growing nodule-like lesion in the Lt. alar area. Excisional biopsy was done for diagnosis. The lesion was totally excised with 2 mm safety margin. Frozen biopsy of the lesion was requested, and all resection margins were proved negative. To cover the raw surface, full thickness skin grafting was performed. The graft was harvested from Rt. posterior auricular area. Tie over dressing was applyed on Lt. alar area. The graft was well taken and healed without any complication in both short term and long term follow up periods of 2 weeks, 1 month, 2 months, and 6 months. Donor site completed healed without any complications. The leiomyoma is benign tumor originated from smooth muscle, and it can be classified into solid leiomyoma, angiomyoma, and epithelioid leiomyoma. Especially, the angiomyoma consists of smooth muscle cell and blood vessel, and it is originated from the tunica media of blood vessel. Angiomyoma alone frequently occurs in the lower extremities as solitary painless subcutaneous tumor. Venous type of angiomyoma in the oral cavity was reported in other references, but on the facial surface it may be the first case reported as paper. So this report can be very meaningful.

  • 강도다리(Platichthys stellatus)의 정자는 대부분의 경골어류에서와 같이 첨체를 가지고 있지 않는 구형의 핵, 짧은 중편 및 꼬리를 가진 전형적인 수중형의 정자 형태를 하였다. 정자의 미세구조는 전자밀도가 높은 염색질 부위를 가지는 핵과 핵 기부에 위치한 깊이 함입된 핵와(nuclear fossa) 그리고 그 속에 기부 중심립과 말단부 중심립이 포함되어 있었다. 두 중심립은 90도의 각도로 배열되어 있었으며, 미토콘드리아는 중편 세포질에 배열되어 있으며 핵의 후반부와 꼬리의 기부를 둘러 싸고 있었다. 꼬리는 축사와 2개의 lateral ribbon로 구성되어 있었다. 이러한 특징들은 가자미류의 공유형질로 나타났다. 그러나 미토콘드리아의 수와 모양, 핵와의 모양과 크기에서는 종 특이적 특징을 나타내었다. 특히 강도다리 정자의 가장 큰 구조적 특징은 basal foot, rootlet 그리고 alar sheets로 구성된 기저체이었다. 이 구조의 형태적 특징은 다른 종들 사이에서 아주 다양하게 나타내었다. 이러한 구조는 가자미목의 계통적 관계를 연구하는데 매우 중요한 형질로 여겨진다.

  • Background: Rehabilitation of normal function and form is essential in cleft lip repair. In 2005, Dr. David M. Fisher introduced an innovative method, named "an anatomical subunit approximation technique" in unilateral cleft lip repair. According to this method, circumferential incision along the columella on cleft side of the medial flap is continued to the planned top of the Cupid's bow in straight manner, which runs parallel to the unaffected philtral ridge. Usually, small inlet incision is needed to lengthen the medial flap. On lateral flap, small triangle just above the cutaneous roll is used to prevent unesthetic shortening of upper lip. This allows better continuity of the Cupid's bow and ideal distribution of tension. Case presentation: As a modification to original method, orbicularis oris muscle overlapping suture is applied to make the elevated philtral ridge. Concomitant primary rhinoplasty also results in good esthetic outcome with symmetric nostrils and correction of alar web. As satisfactory results were obtained in three incomplete and one complete unilateral cleft lip patients, indicating Fisher's method can be useful in cleft lip surgery with functional and esthetic outcome. Conclusions: Clinically applied Fisher's method in unilateral cleft lip patients proved the effectiveness in improving the esthetic results with good symmetry. This method also applied with primary rhinoplasty.

  • Background: Even though degrees of deformation of microform cleft lip are not high, it has to be corrected with various procedures upon conditions and areas since it has various expressions. Many studies have focused on the classifications and procedures, but there are only a few studies on how much these procedures are performed in the actual field. This study aims to analyze the utilization of various procedures upon major correction points. Methods: A total of 52 patients who had been corrected by one surgeon from 1995 to 2011 were enrolled as subjects. Based on the medical records, it was checked whether the incision was made or not along with the correction procedures for alar base and philtral column, Cupid's bow, and vermillion free margin. Results: In case of an incision, full incision (42 times) was conducted most frequently. For alar base and philtral column, muscle re-approximation (25 times) was performed most frequently. However, recently, it was shown that excision on only the affected area and correction with dermis were more likely to be used. For Cupid's bow and vermilion free margin, elliptical excision on the only affected area followed by re-approximation was performed most frequently for 46 times (Cupid's bow) and 44 times (vermilion free margin), respectively. Conclusion: For the correction of microform cleft lip, less invasive procedures are preferred. However, in the actual field, if needed, aggressive procedures consisting of incisions have been conducted to correction. These trends are somewhat changed to utilization of a simple procedure, such as excision on the modified area, followed by a re-approximation rather than complicated procedures using the muscle.

  • Background: Patients with secondary deformities associated with unilateral cleft lip and nose might also suffer from nostril stenosis due to a lack of tissue volume in the nostril on the cleft side. Here, we used full-thickness skin grafts (FTSGs) to reduce nostril stenosis and various methods for skin volume augmentation. We compared the changes in the symmetry of both nostrils before and after surgery. Methods: From February 2016 to January 2020, 34 patients underwent secondary cheiloplasty and open rhinoplasty for secondary deformities of the unilateral cleft lip and nose with nostril stenosis. FTSG was used on the nostril floor, nasal columella, and alar inner lining. The measured nasal profile included the nostril surface, nostril circumference, width of the nostril floor, and distance from the alar-facial groove to the nasal tip. The "overlap area," which was defined as the largest overlapping area when the image of the cleft nostril was flipped to the left and right and overlaid on the image of the normal side nostril, was also calculated. The degree of symmetry was evaluated by dividing the value of the cleft side by that of the normal side of each measured profile and expressed as "ratios." Results: The results of all profile ratios, except for the nostril floor width, became significantly close to 1, which represents full symmetry. The overlap area ratio improved from 62.7% to 77.3%, meaning that the length and width of the nostril as well as the overall shape became similar (p< 0.05). Conclusion: When performing cleft rhinoplasty with nostril stenosis, FTSG is useful to achieve symmetry in the nostril size and shape. Skin grafting is simpler to perform than the other types of local flap, and the results are generally satisfactory.

  • Background: The introduction of presurgical nasoalveolar molding represented a significant departure from traditional molding methods. Developed by Grayson and colleagues in 1993, this technique combines an intraoral molding device with a nasal molding stent. This study aimed to compare the Grayson nasoalveolar molding appliance versus DynaCleft appliance as two methods of presurgical nasoalveolar molding. Methods: A single-blinded, randomized, parallel-arm clinical trial was conducted. Sixteen infants with complete unilateral cleft lip and palate were enrolled and divided into two groups of eight. Group 1 was treated with a modified Grayson nasoalveolar molding appliance that included a nasal stent, while group 2 was treated with DynaCleft elastic adhesive tape and an external nasal elevator. Standardized digital photographs of each infant were taken at baseline and post-treatment using a professional camera. Nine extraoral anthropometric measurements were obtained from each image using image measurement software. Results: The modified Grayson nasoalveolar appliance demonstrated a more significant improvement compared to DynaCleft in terms of alar length projection (on both sides), columella angle, and nasal tip projection. Symmetry ratios also showed enhancement, with significant improvements observed in nasal width, nasal basal width, and alar length projection (p< 0.05). Conclusion: Both the modified Grayson nasoalveolar appliance and DynaCleft appear to be effective presurgical infant orthopedics treatment options, demonstrating improvements in nasolabial aesthetics. The modified Grayson appliance, equipped with a nasal stent, improved nasal symmetry more effectively than DynaCleft, resulting in a straighter columella and a more medially positioned nasal tip.

  • The aim of this study was to clarify the arrangement of the zygomaticus major muscle, and to describe morphology of zygomaticus minor muscle. After a detailed dissection, the zygomaticus muscles were observed in 66 embalmed cadavers. It was found that the insertion of zygomaticus major was divided into superficial and deep bands(42/70, 60%). Zygomaticus minor was inserted not only upper lip also alar portion(5/54, 9.2%). The arrangement and insertion patterns of the zygomaticus muscles in this study are expected to provide critical information for understanding or smile pattern and treatment or fold.

  • For many years a wide variety of surgical techniques for closure of cleft lip has been used. Still many surgeons prefer the Millard's rotation-advancement lip repair because the surgical scar is masked in the philtral crest and the nostril floor, and it improves the relationship of the alar base of the cleft side, producing harmonious symmetry of the nostril and the nostril sill. In addition, it uses and preserves the lip anatomy, returning lip tissue into its normal position, minimizing the amount of tissue that is discarded, and reconstructing the orbicular oris muscle. One of the major disadvantages of this procedure is the lack of accurate measurements. The object of this study is to help in the cleft lip surgery with investing its features and design.
