Excessive gingival display is an esthetic issue that is commonly managed by different procedures. Lip repositioning is a modality to address concerns of affected patients. The aim of this review was to investigate the scientific evidence on outcomes and long-term stability of lip repositioning surgery with or without myotomy. The electronic search was conducted in three databases: MEDLINE, Embase, and the Cochrane Library up to October 2019. No publication status, language, or time restrictions were applied. The electronic search was complemented by a manual search of the reference lists. Three hundred thirty-eight studies were screened by title, and 16 articles remained for data extraction. The included studies assessed the lip repositioning procedure in 144 patients aged between 15-59 years (134 females and 10 males). Based on the available data, lip repositioning with myotomy/muscle containment can be a successful treatment for minor discrepancies in gingival display in selected cases. However, further well-organized controlled clinical trials are recommended to derive a conclusion about the long-term stability compared with other alternatives.

This is a report of 12 cases of esophageal diverticulum treated surgically at the Department of Thoracic and Cardiovascular Surgery, Hanyang University Hospital during the 16 years. 10 patients were female and 2 were male and the age distribution was between 31 and 61 years. Various subjective symptoms were noticed preoperatively. Diagnosis was confirmed by esophagography. The type of esophageal diverticulum were pulsion type in 11 cases and traction type in one case, and they were all located on the mid-thoracic esophagus, but one case was associated with epiphrenic pulsion diverticulum After diverticulectomy with or without myotomy, subjective symptoms disappeared and there were no operative complications and mortality. Indication of myotomy evaluated with motilities status by fluoroscopic finding of X-ray barium study. Recurrence of symptoms was not noticed during follow-up.

Surgical treatment is possible for the obstructive form of hypertrophic cardiomyopathy and transaortic left ventricular septal myectomy and myotomy has been the procedure of choice. If coexisting intrinsic mitral valve disease exists, mitral valve replacement has been performed. But abnormal systolic anterior motion of anterior mitral leaflet[SAM] with intrinsic normal mitral valve disease is the typical feature of IHSS and we prefer not to replace mitral valve. 3 patients underwent transaortic myotomy and myectomy for IHSS with mitral regurgitation. 2 patients of them have coexisting intrinsic mitral valve diseases such as mitral valve vegetation and chorda rupture. Concomittent mitral valve replacement were performed. 1 patient shows SAM of mitral anterior leaflet but has intrinsic normal mitral valve morphologically and transepicardial echocardiogram and direct monitoring of pressure gradient during the operative procedure gives better information for subsided mitral regurgitation. Post operative course during the 12 months follow-up was uneventful.

Sixteen patients with esophageal diverticulum operated on between July 1979 and September 1988 at the Department of Thoracic Surgery of National University Hospital have been studied. There were 2 cases of the pharyngoesophageal diverticula, 12 cases of the midesophageal diverticula, and 2 cases of the epiphrenic diverticula. Twelve cases of midesophageal diverticula consisted of 9 cases of pulsion type and 3 cases of traction type. There were 13 women and three men, whose ages ranged from 25 to 65 years with an average age of 45.5 years. Diverticulectomy alone in three cases, diverticulopexy with myotomy in two cases, and diverticulectomy with myotomy in 11 cases were performed. There were no deaths or morbidity and all patients have achieved marked improvement of their symptoms except four patients who had a concomitant hypopharyngeal carcinoma, had a postoperative recurrence in epiphrenic diverticulum, and had two cases of postoperative transient regurgitation which subsided spontaneously one and one and half year later.

Aesthetic facial profile is mainly determined by cultural background. In some countries, prominent mandibular angle is considered as characteristics, whereas it is considered as unattractive in East Asian countries. Therefore, reduction surgery for prominent mandibular angle is one of the popular cosmetic surgery in theses countries. The anatomical component of the mandibular angle consists of masseter muscle and the angular part of the mandibular ramus. Thus, the mandibular angle reduction can be performed by myotomy or bone reduction or both.

기도흡인은 후두의 고유기능중 방어기능을 소실함으로써 지속되는 경우 하기도에 치명적인 손상을 초래하게된다. 기도흡인에 대한 치료는 고식적 치료법과 수술적 치료법으로 대별되는데 일반적으로 고식적으로 치료법이 우선적으로 선택되어지고 있으나 흡인의 정도가 심하여 하기도에 폐렴, 무기폐 등의 위급한 합병증을 유발하거나 그 원인이 비가역적이어서 탈진 또는 악액질을 초래하는 경우 부득이 수술적 요법율 선택하게 된다. 수술적 요법의 선택시기에 대하여는 논란이 많으나 현재까지는 고통을 받고있는 환자의 상태에 따라 결정되고 있는 실정에 있다. 저자들은 최근 5년간 경험한 만성 기도흡인 환자 6례에 대하여 수술적 요법 즉, cricopharyngeal myotomy 1례, cricopharyngeal with medialization laryngoplasty 1례, laryngeal suspension with cricopharyngeal myotomy 2례, laryngeal diversion 1례, total laryngectomy 1례를 각각 시행함으로써 얻은 치료경험을 분석 검토하여 만성 기도흡인에 대한 치료상의 문제점과 보다 효율적인 치료법의 선택에 도움을 얻고자 문헌고찰과 함께 보고하는 바이다.

Idiopathic cricopharyngeal achalasia is a rare condition that produces oropharyngeal dysphagia. It is caused by spasm of the cricopharyngeus and inability to relax with swallowing. A prominent muscle bar at the upper esophageal sphincter is a typical finding of the esophagogram. Cricopharyngeal myotomy is the treatment of choice. We report a case of cricopharyngeal myotomy for 61-year-old female patient.

Submucosal endoscopy or third-space endoscopy utilizes the potential space between the mucosal and muscularis layers of the gastrointestinal tract to execute therapeutic interventions for various diseases. Over the last decade, endoscopic access to the submucosal space has revolutionized the field of therapeutic endoscopy. Submucosal endoscopy was originally used to perform endoscopic myotomy in patients with achalasia cardia, and its use has grown exponentially since. Currently, submucosal endoscopy is widely used to resect subepithelial tumors and to manage refractory gastroparesis and Zenker's diverticulum. While the utility of submucosal endoscopy has stood the test of time in esophageal motility disorders and subepithelial tumors, its durability remains to be established in conditions such as Zenker's diverticulum and refractory gastroparesis. Other emerging indications for submucosal endoscopy include esophageal epiphrenic diverticulum, Hirschsprung's disease, and esophageal strictures not amenable to conventional endoscopic treatment. The potential of submucosal endoscopy to provide easy and safe access to the mediastinum and peritoneal spaces may open doors to novel indications and rejuvenate the interest of endoscopists in natural orifice transluminal endoscopic surgery in the future. This review focuses on the current spectrum, recent updates, and future direction of submucosal endoscopy in the gastrointestinal tract.
