PURPOSE The previous decade has witnessed increasing emphasis on the technique of trans-sutural distraction osteogenesis (TSDO), a new and challenging procedure to reconstruct deficiencies in craniomaxillofacial bone. The purpose of this study was to determine if locally administered recombinant human bone morphogenetic protein-2(More)
Blepharoplasty is one of the most common aesthetic procedures done today. The protruding fat and lid-cheek junction are the most conspicuous signs of aging that need attention. During zygomatic reduction by an intraoral approach we found occasionally that the orbital fat can be exposed through the perforated periosteum at the inferior obital rim. We(More)
A new technique of osteotomy distraction osteogenesis (ODO) and sutural distraction osteogenesis (SDO) by the use of bone-borne traction hooks is presented. The technique of osteotomy plus distraction osteogenesis is suitable for adult patients. The technique of sutural distraction osteogenesis is suitable for young patients, ages 6 through 12 years. The(More)
Tracheostomy is to establish an artificial airway by making an opening at anterior tracheal wall. Due to the blossom of mechanical ventilation and intensive care unit after 1950s, tracheostomy is the most favorable surgical method to access airway at present. In addition to traditional surgical tracheostomy, percutaneous dilational tracheostomy have gained(More)
BACKGROUND Craniofacial fibrous dysplasia (CFD) often requires surgery to correct facial deformity and prevent functional impairment. However, recurrence is common, and there is no reliable prognostic biomarker. The aim of this paper is to evaluate the possibility of using preoperative alkaline phosphatase (ALP) as a prognostic marker for CFD. MATERIAL(More)
OBJECTIVE To explore the clinical effectiveness of minimally invasive treatment of cyst simplex of sublingual gland by the mucosal bridge-tunnel surgery. METHODS A total of 35 patients were enrolled. Minimally invasive treatment of cyst simplex of sublingual gland was performed by mucosa bridge-tunnel surgery. Two parallel incisions were initially made at(More)
OBJECTIVE To investigate the role of Keap1-Nrf2-ARE pathway in laryngeal carcinoma occurrence and development. METHOD Thirty-five laryngeal carcinoma samples and para-carcinoma tissues were taken from the patients who accepted operation treatment in our hospital from Feb 2012 to Sep 2013. The expression levels of Nrf2 and Keap1 were detected in 35 cases(More)
OBJECTIVE To compare cricothyroid membrane puncture directed tracheostomy (CMPDT) with conventional surgical tracheostomy (ST) and cricothyroidotomy (CT) and to evaluate the feasibility, efficacy and safety of this novel technique. METHODS 15 minipigs were divided randomly into 3 groups, 5 in each. After general anesthesia, CMPDT, ST and CT were performed(More)
This study investigated the effects of a newly-developed scaffold, nano-hydroxyapatite/collagen/poly(L-lactide) (nHAC/PLA), on the attachment, proliferation and osteogenic capability of dog periodontal ligament stem cells (PDLSCs) in vitro and in vivo. Hydroxyapatite/tricalcium phosphate (HA/TCP), a commonly used bone substitute, was used as a positive(More)
