A Hanwoo cow with a delayed gestation and abdominal distension was delivered following PGF_2α injection. There was excessive amniotic fluid, and a male calf was delivered but died immediately. The calf had no eyes and nose, and a cleft palate on the upper jaw. Gross appearance and computed tomography image showed that upper teeth were spread out on both sides due to cleft palate in the upper jaw, and lower jaw and teeth were positioned upward. There were no other brain parts except cerebellum. These findings show a rare case of hydramnios related to fetal congenital deformity in a Hanwoo cow.

The osteotomy for rhinoplasty is a useful method to make the nasal bony pyramid get narrow, correct the deviated nose and prevent the open roof deformity after hump nose resection. The osteotomy for rhinoplasty is divided medial osteotomy, lateral osteotomy and transverse osteotomy. If the osteotomy is well done, it produces very effective and esthetic results. However, the osteotomy has problems that precise operation is often impossible for the difficulty of the access and that the possibility of the complication is very high. We report our clinical experience about the osteotomy for rhinoplasty.

Purpose: Although nasal fractures are often discussed as minor injuries but the incidence of post-traumatic nasal deformity remains high. For decrease the incidence of post-traumatic nasal deformity which require the guideline to optimize the management of acute nasal bone fracture. The aim of this study is analysis of post-traumatic nasal deformity according to Stranc classification. Method: We reviewed 310 patients with nasal bone fracture treated at our hospital from January of 2005 to December of 2006. Result: Post-traumatic complication were divided septal deviation, nasal bone deformity, temporary hyposmia and synechia. Nasal bone deformity include nasal bone deviation, hump, flat nose and minimal nasal bone irregularity. The incidence of total complication rate was 36.4%. The most common complication was nasal deformity(22.9%) followed by septal deviation(19.7%). The most common complication was septal deviation(20%) in frontal impact. The most common complication was nasal deformity(19.5%) in lateral impact. In frontal impact, the incidence of complication rate was plane II(68.8%) followed by plane I(29.9%) and plane III(16.7%). In lateral impact, the incidence of complication rate was plane II (78.8%) followed by plane III(61.5%) and plane I(42.7%). Conclusion: This result can be used to improve longterm results and to reduce the incidence of post-traumatic nasal deformity by predict complication of nasal bone fracture according to Stranc classification.

Background: Infants with deformational plagiocephaly (DP) usually present with cranial vault deformities as well as facial asymmetry. The purpose of this study was to use three-dimensional anthropometric data to evaluate the influence of cranial deformities on facial asymmetry. Methods: We analyzed three-dimensional computed tomography data for infants with DP (n=48) and without DP (n=30, control). Using 16 landmarks and 3 reference planes, 22 distance parameters and 2 angular parameters were compared. This cephalometric assessment focused on asymmetry of the orbits, nose, ears, maxilla, and mandible. We then assessed the correlation between 23 of the measurements and cranial vault asymmetry (CVA) for statistical significance using relative differences and correlation analysis. Results: With the exception of few orbital asymmetry variables, most measurements indicated that the facial asymmetry was greater in infants with DP. Mandibular and nasal asymmetry was correlated highly with severity of CVA. Shortening of the ipsilateral mandibular body was particularly significant. There was no significant deformity in the maxilla or ear. Conclusion: This study demonstrated that the cranial vault deformity in DP is associated with facial asymmetry. Compared with the control group, the infants with DP were found to have prominent asymmetry of the nose and mandible.

The columella, nasal tip, lip relationship in the secondary bilateral cleft deformity remains an enigma and a great challenge for the cleft surgeon. A subset of patients with bilateral cleft lip still require columellar lengthening and nasal correction, despite the advances in preoperative orthopedics and primary nasal corrections. An approach to correct this deformity is described. This consists of 1) lengthening the columella, 2) open rhinoplasty, allowing definitive repositioning of lower lateral cartilages, ear cartilage grafting to the tip and columella when necessary, 3) nasal mucosal advancement, 4) alar base narrowing and 5) reconstruction of the orbicularis oris as required. In surgical repair of the cleft lip nose, the timing of the operation(during lip closure, before or after the puberty growth sput), and the operative technique play a key role in the final result. In this study, 13 cleft lip patients who had undergone a secondary cheilorhinoplasty at the Department of Oral and Maxillofacial Surgery, Pusan National University Hospital were evaluated to check the proper time and method of the operation.

Background Among the various methods for correcting nasal deformity, the composite graft is suitable for the inner and outer reconstruction of the nose in a single stage. In this article, we present our technique for reconstructing the ala and columella using the auricular chondrocutaneous composite graft. Methods From 2004 to 2011, 15 cases of alar and 2 cases of columellar reconstruction employing the chondrocutaneous composite graft were studied, all followed up for 3 to 24 months (average, 13.5 months). All of the patients were reviewed retrospectively for the demographics, graft size, selection of the donor site and outcomes including morbidity and complications. Results The reasons for the deformity were burn scar (n=7), traumatic scar (n=4), smallpox scar (n=4), basal cell carcinoma defect (n=1), and scar contracture (n=1) from implant induced infection. In 5 cases of nostril stricture and 6 cases of alar defect and notching, composite grafts from the helix were used ($8.9{\times}12.5$ mm). In 4 cases of retracted ala, grafts from the posterior surface of the concha were matched ($5{\times}15$ mm). For the reconstruction of the columella, we harvested the graft from the posterior scapha ($9{\times}13.5$ mm). Except one case with partial necrosis and delayed healing due to smoking, the grafts were successful in all of the cases and there was no deformity of the donor site. Conclusions An alar and columellar defect can be reconstructed successfully with a relatively large composite graft without donor site morbidity. The selection of the donor site should be individualized according to the 3-dimensional configuration of the defect.

The simultaneous surgical correction of bilateral cleft lip and nasal deformity has become a more common surgical technique that has greatly changed conventional strategies for secondary nasal correction. Mulliken has been known as one of the earliest proponents for the synchronous repair of bilateral cleft lip and nasal deformity, and he emphasized the responsibility of the treating surgeon to evaluate nasolabial growth by comparing anthropometric measurements with age-matched normal patients. Good outcomes from this surgical method have been reported in clinical cases worldwide. Herein, we describe the management of two cases of bilateral cleft repair, following the principles and methods established by Mulliken. We also provide a relevant review of the literature.

구순열 비변형 환자의 상태, 수술결과 등을 객관적으로 평가할 수 있는 방법의 개발은 구순열의 수술의 술기 등의 평가 및 발전에 많은 도움을 줄 수 있을 것으로 생각되나 아직은 미진하다. 이에 본 논문은 구순열 환자의 사진을 이용해 다음과 같은 요인들을 분석하여 구순열 비변형 정도를 정량적으로 평가하고자 하였다. (1) 비공의 각도 (2) 비공의 중심점 및 중심점사이의 거리 (3) 중첩된 비공의 면적 (4) 비공의 중첩된 면적의 비 등을 각각 비교하였다. 먼저, 8개의 분석요인을 이용하여 임상의 평가점수에 대한 회귀분석을 통하여 회귀식을 획득하였다. 구순열 환자의 수술 경험이 많은 성형외과 의사 세 사람이 상기 대상 환자의 수술 후의 결과를 100 점 만점과 10점 간격으로 판정하였다. 세 명의 성형외과 의사와 개발된 프로그램을 이용한 세 명의 일반인으로부터 얻어진 평가점수의 재현성은 각각 $10.8{\pm}4.6%,\;7.4{\pm}1.8%$로 개발된 프로그램을 이용한 분석이 더 높은 재현성을 보였다. 일치도를 나타내는 kappa 통계량은 세 명의 성형외과 의사에서는 0.43, 세 명의 일반인에서는 0.83으로 프로그램을 이용한 일반인의 일치도가 훨씬 더 높게 나타났다. 회귀분석을 통한 평가와 임상의의 평가점수에서의 상관관계는 0.642이었으며, 신경회로망을 통한 평가와 임상의의 평가점수에서의 상관관계는 0.798로 신경회로망을 통한 분석이 임상의의 평가점수와 상관관계가 더 높은 것으로 나타났다. 결론적으로, 개발된 신경회로망 모델은 의사의 주관적인 평가보다 더 높은 재현성, 일치도, 상관관계를 보여주며 이는 임상의에서 구순열 비변형의 정도를 객관적이고 손쉽게 적용할 수 있을 것이라 사료된다.

Oblique facial cleft is a rare congenital deformity. Its incidence has been reported as 0.24% of all reported cases of facial cleft. We report on a patient who had a left-sided oblique facial cleft with anopthamia, including lip and palate, nose alar base, and medial canthus. The patient also had a right-sided oblique facial cleft, which included lip and palate, nose alar base, medial canthus, and upper eye brow. Primary closure of the facial cleft was performed using multiple Z-plasty after excision of scar tissue.
