Ranula is a mucocele caused by extravasation of the sublingual gland on the floor of the mouth. The most common presentation is a cystic mass in the floor of the mouth. A portion of the sublingual gland could herniate through the mylohyoid muscle, and its extravasated mucin can spread along this hiatus into submandibular and submental spaces and cause cervical swelling. This phenomenon is called plunging ranula. A variety of treatments for ranula has been suggested and include aspiration of cystic fluid, sclerotherapy, marsupialization, incision and drainage, ranula excision only, and excision of the sublingual gland with or without ranula. Those various treatments have shown diverse results. Most surgeons agree that removal of the sublingual gland is necessary in oral and plunging ranula. Four patients with ranula were investigated retrospectively, and treatment methods based on literature review were attempted.

One case of surgically treated sliding esophageal hiatal hernia associated with bleeding gastric ulcer is presented. The patient was 73 years-old woman who had suffered from epigastric heartburn, indigestion, and melena since 3 months prior to admission. Esophageal hiatal hernia was suspected on the simple chest film and the diagnosis was confirmed by tetralogic barium study of the gastrointestinal tract. Hematemesis and melena were persisted so emergent thoracotomy and abdominal exploration were undertaken. Repair of hiatal hernia by constricting suture around relaxed esophageal hiatus was made and plication sutures were Inserted between esophagogastric junction and median arcuate ligament of diaphragm. Concomittently, subtotal gastrectomy with Billroth II procedure was performed to removal of large bleeding ulcer on the lesser curvature of the stomach antrum. Postoperative course was uneventful.

이 연구에서는 경막바깥신경성형술 시행에 있어서 중요한 엉치뼈틈새에서 경막주머니종말부 및 척수원뿔 사이의 거리를 자기공명영상에서 계측하여 한국인의 생체 연구에 대한 기초 자료를 제공하고자 한다. 허리통증으로 자기공명영상을 촬영한 환자 중 척추압박골절이나 척추전방전위증 그리고 기형 등이 없는 환자 200명(남자 88명, 여자 112명)을 대상으로 하였으며, 평균 연령은 54.3세(20~84세), 평균 신장은 161.3 cm(135~187 cm)이었다. T2강조 자기공명영상을 이용하여 엉치뼈틈새에서 경막주머니종말부 그리고 척수원뿔 사이 거리를 계측하여 성별 및 신장에 따른 상관관계를 분석하였다. 엉치뼈틈새꼭지에서 경막주머니종말부까지 거리는 $62.8{\pm}9.4mm$, 엉치뼈틈새꼭지에서 척수원뿔까지 거리는 $232.2{\pm}21.8mm$, 엉치뼈틈새꼭지에서 경막주머니종말부 사이 최소 거리는 34.8 mm, 최대 거리는 93.9 mm, 엉치뼈틈새꼭지에서 척수원뿔 사이 최소 거리는 155.0 mm, 최대 거리는 284.0 mm이었다. 엉치뼈틈새꼭지에서 경막주머니종말부까지, 그리고 엉치뼈틈새꼭지에서 척수원뿔까지 거리는 모두 여성이 남성보다 짧게 나타났고(p<0.05), 엉치뼈틈새꼭지에서 경막 종말부 및 척수원뿔 사이 거리는 신장에 대해 유의한 상관관계를 보였다(p<0.01). 이 연구의 결과는 한국 성인의 엉치뼈틈새에서 경막주머니종말부 및 척수원뿔 사이 거리에 대한 생체 계측 자료를 제공하며, 경막바깥공간에 대한 임상적 시술의 안전성 확보와 한국인의 체형에 맞는 카테터 개발에 도움이 될 것이라 생각한다.

Background: The blind sacroiliac joint (SIJ) block cannot always be performed accurately; it is commonly performed in the office based setting because intraarticular and periarticular injections are effective for SIJ pain. However, knowledge on the surface anatomy of the SIJ is lacking. The purpose of this study was to analyze the surface anatomical location of the posterior-inferior margin of the SIJ. Methods: After informed consent was obtained, fifty patients undergoing SIJ block in the prone position were examined. The oblique angles where the anterior-inferior margin and the posterior-inferior margin of the SIJ overlap on X-ray were evaluated. In addition, the surface anatomical relationships between the posterior-inferior margin of the SIJ on X-ray and the posterior superior iliac spine (PSIS) and sacral hiatus by palpation were assessed. Results: The oblique angle was $5.4{\pm}2.9^{\circ}$. The vertical and transverse distance between the posterior-inferior margin of the SIJ and PSIS were $3.8{\pm}0.8cm$ and $0.9{\pm}0.6cm$, respectively. The vertical and transverse distance between the posterior-inferior margin of the SIJ and the midpoint of the sacral hiatus were $3.4{\pm}0.7cm$ and $3.9{\pm}0.6cm$, respectively. Only the vertical distance between the posterior-inferior margin of the SIJ and PSIS showed significant difference between the male and the female groups (P = 0.0016). Conclusions: The measurements in this study can be used as a reference standards for the blind SIJ block.

A bladder diverticulum occurs when the bladder mucosa herniates or protrudes through the muscular wall of the baldder. The majority of congenital bladder diverticula occurs in males. They are the most common in the region of the bladder base, most frequently in the region of the ureteral hiatus, in which case they are known as Hutch's diverticula. They can give rise to obstruction or reflux. We had experienced a case of bilateral Hutch's diverticulum associated with vesicoureterai reflux in a 23 month old male. Chief complaints were urinary frequency and dysuria. Voiding cystourogram and CT scan revealed large bilateral Hutch's diverticulum with bilateral vesiciureteral reflux grade VI. There was evidence of urinary infection. This patient was successfully treated by ureteroneocystostomy. We report this case with a brief review of related literatures.

Objective : Several conservative treatments have been tried in peripheral facial nerve paralysis, because 80% of patients recover spontaneously. Surgical decompression may be helpful to the residual, medically intractable patients. We present here our experiences of facial nerve decompression via middle fossa approach, which seems to be one of good surgical therapeutic options for medically refractory peripheral facial nerve paralysis. Method : Three cases of medically intractable peripheral type facial paralysis were microscopically operated via middle cranial fossa approach to decompress the labyrinthine segment of the facial nerve and geniculate ganglion by searching landmarks of middle meningeal artery, greater superficial petrosal nerve and facial hiatus. Results : After operation, two cases of Bell's palsy improved substantially and one case of post-traumatic facial paralysis improved partially. Conclusion : This report is presented to describe the surgical facial nerve decompression via middle fossa for early control of peripheral type facial paralysis. Surgical decompression of edematous peripherally paralysed facial nerve could be preferred to conservative treatment in some patients although more surgical experience should be required.

We propose a robust event date model to estimate the date of a target event by a combination of individual dates obtained from archaeological artifacts assumed to be contemporaneous. These dates are affected by errors of different types: laboratory and calibration curve errors, irreducible errors related to contaminations, and taphonomic disturbances, hence the possible presence of outliers. Modeling based on a hierarchical Bayesian statistical approach provides a simple way to automatically penalize outlying data without having to remove them from the dataset. Prior information on individual irreducible errors is introduced using a uniform shrinkage density with minimal assumptions about Bayesian parameters. We show that the event date model is more robust than models implemented in BCal or OxCal, although it generally yields less precise credibility intervals. The model is extended in the case of stratigraphic sequences that involve several events with temporal order constraints (relative dating), or with duration, hiatus constraints. Calculations are based on Markov chain Monte Carlo (MCMC) numerical techniques and can be performed using ChronoModel software which is freeware, open source and cross-platform. Features of the software are presented in Vibet et al. (ChronoModel v1.5 user's manual, 2016). We finally compare our prior on event dates implemented in the ChronoModel with the prior in BCal and OxCal which involves supplementary parameters defined as boundaries to phases or sequences.

Transhiatal gastric transposition was performed in two case of long gap esophageal atresia without tracheoesophageal fistula. The patients were a 12 months old female and an 18 months old male. Stamm type gastrostomies were performed at other hospitals in both cases. The stomach was mobilized preserving the right gastric artery, the right gastroepiploic artery and spleen. A portion of the proximal and the distal esophageal segment were excised by transcervical and transhiatal route, respectively. The mobilized stomach was pulled up to the neck through the esophageal hiatus and posterior mediastinum. The esophagogastrostomy, the only one anastomosis of this procedure, was performed in the neck. There was no clinical evidence of anastomotic leakage, stricture, regurgitation, difficulty of gastric emptying, hoarseness or respiratory problem. Transhiatal gastric transposition seems to be a safe and easy alternative surgical procedure for esophageal replacement in long gap esophageal atresia.
