Randomized Controlled Trial
A study on respiratory management in acute postoperative period by nasal high flow for patients undergoing surgery under general anesthesia.
In head and neck surgery where the oropharyngeal area is the operative field, postoperative respiratory depression and upper airway obstruction are common. Therefore, supplemental oxygen is administered to prevent severe postoperative early hypoxemia. However, a high concentration of oxygen increases the likelihood of secondary complications, such as carbon dioxide (CO2) narcosis. ⋯ This exploratory study will investigate the use of NHF without supplemental oxygen as an effective respiratory support during the acute postoperative period. TRIAL REGISTRATION:: The study was registered the jRCTs072200018. URL https://jrct.niph.go.jp/latest-detail/jRCTs072200018.

Amelogenesis imperfecta (AI) is an enamel defect and is often associated with the anterior open bite (AOB) and transverse maxillary deficiency. It is known that in such cases when AI and AOB appeared together, posterior maxillary impaction with or without bilateral mandibular ramus osteotomies is a frequently preferred treatment option. ⋯ Usage area of virtual 3D anatomical models reconstructed from Cone Beam Computed Tomography (CBCT) data is expanding day by day for both diagnosis and surgical planning. The aim of this study is to present a patient with AI and AOB and transverse maxillary deficiency and management of this case with virtually planned two-segment Le fort I and sagittal split ramus osteotomies followed by prosthetic rehabilitation.

Untreated dental caries or even dental manipulations, such as a tooth extraction, might cause direct spread of an odontogenic infection and consequently the development of life-threatening conditions such as deep neck infections (DNI). The most common source of DNI is of odontogenic origin (38.8-49%). Abscess formation or cellulitis can lead to life-threatening complications, despite new diagnostic imaging technology and widespread availability of antibiotics. ⋯ DNI treatment on an emergency basis requires proper diagnosis and effective management. To confirm diagnosis and prevent serious complications, it is essential for physicians to recognize the spaces of the head and neck that are likely to be affected by DNI.

[Clinical value of V-shaped concealed incision in parotid benign tumors].
Objective:The aim of this study is to explore the clinical value of V-shaped concealed incision in parotid benign tumors surgery. Method:Thirty-two patients with benign parotid tumors who were hospitalized from January 2016 to December 2017 were selected. All patients were treated with a V-shaped incision approach, starting from the anterior dermatoglyph of the tragus,extending downward to the earlobe and backward to the posterior earlobe, which formed an intersection point of the earlobe for parotid benign tumors,superficial lobectomy and facial nerve dissection. ⋯ It is not easy to damage the facial nerve and the ear nerve. After the operation,the patient has a satisfactory facial shape. The parotid gland secretion function is basically normal,which is superior to the traditional S-shaped incision and has good clinical application value.

Randomized Controlled Trial
Nasopharyngeal Tube Effects on Breathing during Sedation for Dental Procedures: A Randomized Controlled Trial.
Dental procedures under sedation can cause hypoxic events and even death. However, the mechanism of such hypoxic events is not well understood. ⋯ Patients under sedation for dental procedure frequently encounter obstructive apnea/hypopnea events. The majority of the obstructive apnea/hypopnea events were not detectable by pulse oximetry. The effectiveness of a small-diameter nasopharyngeal tube to mitigate the events is limited.
