배경: 대동맥 근부를 보존하는 심장수술이 점차 늘어남에 따라 대동맥 근부의 해부학적 구조에 대한 중요성 또한 증가하고 있다. 본 연구는 외과적 관점에서 필요한 대동맥 근부를 한국인 해부학 실습용 시신에서 실측하여 대동맥 근부의 진단 및 수술적 처치의 기준으로 하고자 한다. 대상 및 방법: 사인이 심혈관 질환이 아닌 시신 62구 중 대동맥 판막이 쌍엽인 1구, 기술적 오류로 대동맥 근부가 손상된 4구, 고정기간 중 변형이 심한 10구를 제외한 47예를 대상으로 하였다. 각 교련사이 간격, 대동맥 동의 높이, Sinotubular junction 및 aortic annulus의 길이를 측정하여 비교하였다. 결과: 시신의 사망 나이는 평균 61.3이었으며 남성이 31, 여성이 16구였다. 각 교련사이 간격은 Right coronary sinus $20.73{\pm}2.23mm$, Non coronary sinus $19.34{\pm}2.08mm$, Left coronary sinus $18.58{\pm}2.15mm$였다. 각 대동맥동의 높이는 Right coronary sinus $20.59{\pm}2.48$, Non coronary sinus $18.61{\pm}2.26mm$, Left coronary sinus $17.95{\pm}19mm$였으며, 통계 분석에서 교련사이에 길이 및 대동맥동의 높이는 Right coronary sinus가 가장 컸으며, Non coronary sinus, Left coronary sinus 순으로 나타났다. Sinotubular junction의 길이는 $70.73{\pm}5.94mm$, aortic annulus는 $77.94{\pm}5.63mm$였으며 Sinotubular junction의 길이, 대동맥 판륜의 길이와 대동맥 판륜에 대한 Sinotubular junction의 길이의 비를 각각 나이와 비교 분석했을 때 상관관계가 없었다(p=0.920, p=0.111, p=0.073). 대동맥 판륜과 sinotubular junction의 기울기는 $2.03^{\circ}$에서 $7.77^{\circ}$ (평균$=4.90^{\circ}$)였다. 결론: 각 교련 사이 간격 및 대동맥동의 높이는 non-parametric ANOVA test 결과 Right coronary sinus, Non coronary sinus, Left coronary sinus의 순으로 유의한 크기차이를 보였다(p=0.00). Sinotubular junction의 둘레 길이는 대동맥 판륜의 길이보다 9.3% 작았고 sinotubular junction이 aortic annulus에 대해 좌후측으로 기울어져 있었다.

Purpose: The purpose of the present retrospective cohort study was to investigate the incidence of sinus perforation during endodontic microsurgery and to assess healing of cases with sinus perforation. Materials and Methods: Clinical and radiographic records were collected from patients who were treated with endodontic microsurgery in the Microscope Center of the Department of Conservative Dentistry at Yonsei University College of Dentistry, Seoul, Korea, between March 2001 and January 2016. To determine the incidence of sinus perforation, all cases involving maxillary premolar and molar teeth were assessed, and cases with perforation of maxillary sinus during the procedure were counted. To assess the outcome of the endodontic microsurgery, cases with sinus perforation were recalled at least 1 year after surgery. Result: Two hundred and forty-nine maxillary premolars and molars were treated with endodontic microsurgery. Among these cases, 16 cases had sinus perforations. Overall incidence of sinus perforation was 6.4%. Thirteen cases with sinus perforation were followed up for 1 year after endodontic microsurgery. Outcome assessment revealed that 2 of 13 cases with sinus perforation had failed. The success rate of endodontic microsurgery with sinus perforation was 84.6%. Conclusion: Endodontic surgery performed using microsurgical techniques decreases the risk of sinus perforation. Predictable outcomes of endodontic microsurgeries and healing of sinus membrane can be expected with adequate treatment steps and careful periodic follow-ups in cases with maxillary sinus perforations.

Sinus pericranii is a rare vascular anomaly characterized by abnormal venous communication between the inner and outer regions of the cranial cavity. Here, we report a case of sinus pericranii and venous malformations in the right periorbital region of a 2-year-old girl. Radiologic findings showed venous malformations in the right parietal region communicating with the superior sagittal sinus in the intracranial region. There were notable improvements following surgical resection for the abnormal venous lesions and several sclerotherapies. Presence of a bluish and pulsating mass on the scalp, which showed bruit on auscultation, may indicate sinus pericranii, which should be included in the differential diagnosis.

Sinus lifting was introduced for prosthetic reconstruction in 1960 decades by Boyne and is specifically used for implant surgery in maxillary posterior region with insufficient bony height and has been indicated for reconstruction of oro- antral and palato-alveolar cleft. We report that subtotal maxillectomy using sinus lifting and skin graft in mild maxillary cancer cases results in good prevention of oro-antral and oro-nasal fistula by preserving intact maxillary sinus mucosa and improves better functional outcome after maxillectomy.

Aspergillosis of the maxillary sinus was rare disease, but it was increasing tendency with overuse antibiotics, streoid hormones, and anticanncerous agents. The clinical features and X-ray findings are similar to chronic suppurative paranasal sinusitis. Aspergillosis of the maxillary siuses may occur as a chronic diseae in an otherwise healthy person. This infection is usually confined to a single paranasal sinus, the maxillary antrum, though it can involve the orbit and may initiate with findings of proptosis and decreased vision. The disease is characterized by a wide range of initial symptoms, and should be considered as a possible diagnosis in sinusitis refractory to antibiotics and antral lavage. The choice of treatment of this disease is radical surgery and adjunctive systemic antifungal therapy. We experienced a case of right maxillary sinus aspergillosis in a 34 years old male who has dull pain on Rt. zygoma area, and a case of left maxillary sinus aspergillosis in a 30 years old male who had been suffered from nasal stiffness and frontal headache for 3-4 years. We reported two cases with review of literature.

Maxillary sinus hypoplasia (MSH) is an uncommon clinical disease that represents a persistent decrease in sinus volume, which results from centripetal reaction of the maxillary sinus walls. We present a unilateral MSH case of a 46-year-old male patient with a history of nasal obstruction and headache for 3 years. He had a history of Caldwell Luc operation (CLOP) 10 years ago, and no enophthalmos, hypoglobus or facial asymmetry. After confirming the right diagnosis of MSH, filled with bone in the computed tomography scan, hyperplastic bone was removed by the CLOP approach. The uncinate process and infundibular passage were found to be degenerated and ostium was also examined to be obstructed under endoscopic confirmation. MSH can be mistaken for chronic maxillary sinusitis because of the plain x-ray appearance, so the aggravated state of MSH can be the result of surgeon's misjudgment. With additional literature reviews, this rare experience is first introduced in our Korean oral and maxillofacial surgery field.

A carotid-cavernous sinus fistula is a rare condition in which an abnormal communication exists between the internal or external carotid artery and the cavernous sinus. It typically occurs within a few weeks after craniomaxillofacial trauma. In most cases, the carotid-cavernous sinus fistula occurs on the same side as the craniomaxillofacial fracture. We report a case of delayed carotid-cavernous sinus fistula that developed symptoms 7 months after the craniomaxillofacial fracture. The fistula developed on the side opposite to that of the craniomaxillofacial fracture. Based on our experience with this case, we recommend a long follow-up period of 7-8 months after the occurrence of a craniomaxillofacial fracture. We also recommend that the follow-up should include consideration of the side contralateral to the injury.

Background: Mucous retention cyst refers to a cyst made by expansion due to the blockage of the salivary gland near the maxillary sinus, and it is surrounded by epithelial cells. Most of them are small; therefore, they cannot be found well and are frequently with antral polyp. The aim of this study was to evaluate the clinical prognosis of sinus bone graft in patients with mucous retention cyst. Methods: This study was performed retrospectively on 23 patients who had sinus bone graft. Group 1 was 8 patients (10 sinuses) who had a mucous retention cyst, and group 2 was 15 patients (17 sinuses) who had no pathologic history about the maxillary sinus. For these patients, sinus bone graft was performed using the lateral approach technique. The total 51 implants were placed 6.22 weeks on the average after sinus bone graft. Sinus membrane perforation during operation, postoperative complications, marginal bone loss after restorative function, implant success rate, and survival rate were analyzed. Results: There was no complication in group 1, and there were three complications in group 2. In group 2, two cases of implants failed. The types of postoperative complications consisted of two minor infections and one wound dehiscence. Two implants of total 51 implants were removed, and the survival rate of implants was 96.08 % (group 1 100 %, group 2 93.5 %). The total success rate of implants was 92.2 % (group 1 95 %, group 2 90.3 %). Conclusions: The clinical prognosis was not affected by the presence of mucous retention cyst.

Background The efficacy of Limberg flap reconstruction for pilonidal sinus with acute abscess remains unclear. This study aimed to compare outcomes after Limberg flap reconstruction for pilonidal sinus disease with and without acute abscess. A secondary objective was to perform a review of the literature on the topic. Methods A retrospective chart review was conducted of all patients who underwent excision and Limberg flap reconstruction for pilonidal sinus from 2009 to 2018. Patient demographics, wound characteristics, and complication rates were reviewed and analyzed. Results Group 1 comprised 19 patients who underwent Limberg flap reconstruction for pilonidal sinus disease without acute abscess and group 2 comprised four patients who underwent reconstruction for pilonidal sinus disease with acute abscess. The average defect size after excision was larger in group 2 than group 1 ($107.7{\pm}60.3cm^2$ vs. $61.4{\pm}33.8cm^2$, respectively). There were no recurrences, seromas or cases of flap necrosis postoperatively. There was only one revision surgery needed for evacuation of a postoperative hematoma in group 1. There were comparable rates of partial wound dehiscence treated by local wound care, hematoma, need for revision surgery and minor infection between group 1 and group 2. Conclusions Limberg flap reconstruction for pilonidal sinus in the setting of acute abscess is a viable option with outcomes comparable to that for disease without acute abscess. This practice will avoid the pain and cost associated with a prolonged local wound care regimen involved in drainage of the abscess prior to flap reconstruction.

Purpose: Congenital spinal dermal sinus tract is a rare lesion connecting skin to deeper structures including neural tissue. It results from the failure of the neuroectoderm to separate from the cutaneous ectoderm in the third to fifth week of gestation. The common locations are the lumbosacral and occipital regions. Sometimes it extends to spinal canal. In this paper we report a case of congenital spinal dermal sinus tract in the coccyx. Methods: A 21-month-old male child born after an uncomplicated full-term pregnancy was admitted to our institute with a midline dermal sinus and a cartilaginous protrusion in the coccygeal region. There were no signs of infection. Neurologic examination showed no functional deficit in both lower limbs. He was treated with complete excision of the tract and an underlying accessory cartilage. Results: The spinal dermal sinus tract was extended from the skin to the coccyx. The stalk was loosely attached to the accessory cartilage of coccyx. At that point, it was dissected from the accessory cartilage and resected. The accessory cartilage was also resected at the bone and cartilage junction. During the follow-up period of 6 months, the wound healed well without any complication nor recurrence. Conclusion: Congenital spinal dermal sinus tract is known as a form of spinal dysraphism. In order to prevent complications, timely surgical intervention including complete resection of sinus tract with correction of associated abnormalities is of utmost importance.
