PURPOSE: The purpose of this study was to examine the effects of frozen gauze with normal saline on thirst and the oral health of patients with nasal surgery. METHODS: A quasi-experimental, nonequivalent control group pretest-post test design was used. Participants (n=52) received either gauze frozen with normal saline (n=26), or wet gauze (n=26). The subjective thirst level and oral health of the participants were assessed before the intervention, 30 minutes after the first intervention, 30 minutes after the second intervention, and 30 minutes after the third intervention. RESULTS: After oral hygiene was provided twice, the thirst level was improved in patients receiving the gauze frozen with normal saline. After oral hygiene was provided a third time, the thirst level was improved in patients receiving the gauze frozen with normal saline. CONCLUSION: Gauze frozen with normal saline can be effective for oral hygiene in reducing the thirst level and improving the oral health in nasal surgery patients.

OBJECTIVETo summarize the application of 909 anterolateral thigh myocutaneous flaps in the repair of oral and maxillofacial defects and to examine their benefits in maxillofacial reconstruction of these defects.

METHODSPatients were recruited from January 2004 to December 2012 in the Department of Oral and Maxillofacial Surgery of the Second Xiangya Hospital of Central South University. All patients underwent reconstructive surgery with anterolateral thigh myocutaneous flaps, and patient age ranged from 19 to 81 years with a mean of 51.2 years. There were 761 flaps showing single lobe and 148 flaps showing a multi-island pedicle. The largest area among the single flaps was 28 cm × 12 cm, and the smallest was 4 cm × 2 cm.

RESULTSAmong the 909 transferred flaps, 882 survived and 27 showed necrosis, with a survival rate of about 97.0%. The common complications at flap donor site were poor wound healing 9.6% (87/909), localized paresthesia 61.0% (500/820), and altered quadriceps force 15.0% (123/820). No case was presented with local serious complications, and 90% of the patients achieved good functional recovery and aesthetically acceptable results after the reconstruction by anterolateral thigh myocutaneous flaps.

CONCLUSIONSThe anterolateral thigh myocutaneous free flaps are more suitable for oral and maxillofacial defects than other flaps and should be preferred.

PURPOSE: There has been no attempt to establish an objective implant surgical evaluation protocol to assess residents' surgical competence and improve their surgical outcomes. The present study presents a newly developed assessment and rating system and simulation model that can assist the teaching staffs to evaluate the surgical events and surgical skills of residents objectively. METHODS: Articles published in peer-reviewed English journals were selected using several scientific databases and subsequently reviewed regarding surgical competence and assessment tools. Particularly, medical journals reporting rating and evaluation protocols for various types of medical surgeries were thoroughly analyzed. Based on these studies, an implant surgical technique assessment and rating system (iSTAR) has been developed. Also, a specialized dental typodont was developed for the valid and reliable assessment of surgery. RESULTS: The iSTAR consists of two parts including surgical information and task-specific checklists. Specialized simulation model was subsequently produced and can be used in combination with iSTAR. CONCLUSIONS: The assessment and rating system provided may serve as a reference guide for teaching staffs to evaluate the residents' implant surgical techniques.

PURPOSE: The level of the implant above the marginal bone and flap design have an effect on the bone resorption during the healing period. The aim of this study is to detect the relationship between the level of the implant at the implant placement and the bone level at the healing period in the mesial and distal side of implants placed with flapless (FL) and full-thickness flap (FT) methods. METHODS: Twenty-two nonsubmerged implants were placed with the FL and FT technique. Periapical radiographs were taken of the patient at implant placement, and at 6 and 12 weeks. By using computer software, bone level measurements were taken from the shoulder of the healing cap to the first bone implant contact in the mesial and distal side of the implant surface. RESULTS: At 6 weeks, the correlation between the crestal bone level at the implant placement and crestal bone level of the FT mesially was significant (Pearson correlation coefficient=0.675, P<0.023). At 12 weeks, in the FT mesially, the correlation was nonsignificant (Spearman correlation coefficient=0.297, P<0.346). At 6 weeks in the FT distally, the correlation was nonsignificant (Pearson correlation coefficient=0.512, P<0.107). At 12 weeks in the FT distally, the correlation was significant (Spearman correlation coefficient=0.730, P<0.011). At 6 weeks in the FL mesially, the correlation was nonsignificant (Spearman correlation coefficient=0.083, P<0.809). At 12 weeks in the FL mesially, the correlation was nonsignificant (Spearman correlation coefficient=0.062, P<0.856). At 6 weeks in the FL distally, the correlation was nonsignificant (Spearman correlation coefficient=0.197, P<0.562). At 12 weeks in the FL distally, the correlation was significant (Pearson correlation coefficient=0.692, P<0.018). CONCLUSIONS: A larger sample size is recommended to verify the conclusions in this preliminary study. The bone level during the healing period in the FT was more positively correlated with the implant level at implant placement than in the FL.
