Objective To evaluate the clinical outcome of the buccal fat pad flap in reconstruction of defects of the oral mucosa. Methods From May 1998 to July 2004, 42 patients with oral mucodefects were treated with buccal fat pad flap. Of them, there were 26 males and 16 females, aging 25-76 years. The defect was caused by buccal squamous carcinoma in 7 cases, by buccal leukoplakia in 5 cases, by squamous carcinoma of soft palate in 7 cases, by adenoid cystic carcinoma of palate in 8 cases, by carcinoma of maxillary sinus in 6 cases, by maxillo-alveolar angioma in 5 cases and by keratocyst of maxilla in 4 cases. The locations were buccal mucosa, maxillary sinus and soft palate. The size of defect ranged from 3.0 cm×3.0 cm to 6.5 cm×4.0cm.Results Forty-one cases achieved healing by first intention, except one case because of large defect. Edema faded and epithelization occurred after 4 weeks of operation. Complete epithelization was observed after 6 weeks of operation. Thirty-five cases were followed up 3 months to 5 years. Therewere no obvious differences in layers, color, elasticity, and texture between repaired region and adjacent mucosa. Conclusion The buccal fat pad flap is useful in reconstructing the muco-defects (less than 6.5 cm in diameter) of the posterior maxilla and buccal region without considerable complication. The multiplex blood supply, facility in accessing and minimal donor site morbidity make it a reliable soft tissue graft. The main shortcoming is its limited size.
Objective To compare the reconstructive method of oral and maxillofacial defect with free tissue flaps. Methods The clinical materials were collected from 1 973 reconstructive cases between January 2000 and June 2004 and analyzed in terms of the distribution of age, gender,disease type, defect location, reconstructive method and the incidence of vascular crisis of free flaps as well as success rate of free flap respectively. SAS 6.12 was adopted for statistical analysis. Results A total of 1 973reconstructive cases includded 764 in middle age (＞45 years to ≤60 years, 38.72%), 527 in old age (＞60 years, 26.71%), 450 young adults (＞28 years to ≤45 years, 2281%), 187 in young age (＞14 years to ≤28 years, 9.48%) and 45 children(≤14 years, 2.28%). The ratio of male to female was 1.5∶1. The ratio of benign to malignancy lesion was 1∶1.94. The tongue defect accounted for 20.63%, followed by mandibular defect(1738%), parotid defect(13.74%)，buccal defect(12.72%), maxillary defect(8.16%), oral pharynx defect (7.60%), floor of mouth defect(5.68%) and others (14.09%). Vascular free flap transfers accounted for 45.82%(90.4), followed by axial flap(38.17%,753), random flap(10.19%,201), avascularizedbone graft (1.52%, 30) and others(4.30%, 85). The most frequently used flap was the forearm flap(594 cases), followed by the fibula free flap(143 cases) and the pedicled pectoralis major myocutaneous flap(369 cases); these three flaps accounted for 56.06% (1 106/1 973).In 47 free tissue flaps(5.20%) having vascular crisis, 30 were saved (63.83%). The success rate of total free tissue flaps was 98.19%(923/940). Conclusion The majority of reconstructive cases of oral and maxillofacial defects is the middle aged andthe old aged male patients with malignancy. The tongue defect accounts for about one fifth of all the cases. The vascularized free flap has a high success rate, so it is a main method for reconstruction of oral and maxillofacial defects. The forearm flap, the fibular free flap and the pedicled pectoralis major myocutaneous flap are the main management for repairing oral and maxillofacial defects.

Objective To develop an evaluation tool for the screening of high risk population for oral complications in critically ill patients, which can be performed accurately and scientifically. Methods Basing on the related foreign oral assessment scale, combined with the method of brainstorming, expert consultation, method of clinical status and so on, the item pool of the assessment scale was determined. Five nursing experts and two oral experts assessed the content validity and 50 ICU nurses were tested. Then, the screening accuracy of the assessment scale was proved by application in 100 critically ill patients selected randomly. Results The Cronbach’s a coefficient of final version of the High Risk Assessment Scale for Oral Complications in Critically Ill Patients (including seven parts contents of oral health assessment and oral pH value test) was 0.815, the content validity index (Sr-CVI/Ave) was 0.932. The results of 50 nurses to the 91.2% assessment items of the assessment scale were very important and important. For screening related indicators of oral complications in high-risk patients, the sensitivity of the assessment scale was 97.53%, the specificity was 94.11%, the positive predictive value was 98.75%, the negative predictive value was 88.89%, and the crude agreement was 95%. Conclusion There are good reliability, validity and a high accuracy of screening test in the High Risk Assessment Scale for Oral Complications in Critically Ill Patients. It can be used for screening patients at high risk for oral complications in critically ill patients, and help clinical nurses to complete the oral health status of the critically ill patients quickly.
【摘要】目的探讨颌下腺移位术对预防急性放射性口腔黏膜反应及口干燥症的临床效果。方法2007年7月2009年6月间选择40例患者进行前瞻性临床对照研究。治疗组20例,在放疗前将颌下腺移位至颊下区。对照组20例不行颌下腺移位术。观察放疗中两组急性口腔黏膜反应,测定放疗前后唾液分泌量的变化,放疗后3个月进行口干燥程度问卷调查。结果治疗组急性口腔黏膜反应明显轻于对照组(Plt;0.05)。治疗组放疗后3个月移位术侧颌下腺摄取、排泌功能均明显较对照好,两组比较有统计学意义(Plt;0.05)。结论颌下腺移位术预防鼻咽癌放疗后口干燥症的临床近期疗效较好,可改善鼻咽癌患者放疗后的生活质量。
Objective A systematic review was conducted based on the domestically published literature for improving the quality of oral nursing care.Methods The terms "oral nursing care", "oral hygiene care", "mouth care" were used to search related studies in Chinese databases (up to April 30, 2004) along with handsearching additional studies. Four authors screened and selected the studies, appraised the methodological quality and extracted data from these selected studies. The results were presented by description or Meta-analysis. Results A total of 28 studies were identified, of which 6 were excluded. The methodological quality varied among the studies, 7 scored as B, 15 as C (11 randomized controlled trials, 4 quasi-randomized trials). A total of 2 372 patients were observed including some were critically ill, or intubated, or receiving radiotherapy or chemotherapy or undergoing surgical operations.Six authors of RCT replied and four of them provided more information on methods of randomization. Data analysis revealed that traditional oral nursing procedure was suitable for the severely sick patients who could not take self-care. Brushing and gargling were suitable for conscious patients who could use their hands. Tea and toothpaste were safe, economical and convenient oral nursing agents. Oral pH was a useful index for the selection of oral nursing agents and mouthwashes. A gargle containing sodium bicarbonate was used in the acidic oral environment and reduced fungal infection. The mouthwash with tea polyphenols had good effect for oral health, and might be as the first choice for prophylaxis of stomatitis induced by radiotherapy and/or chemotherapy. Some mouthwashes developed by Chinese herbs improved oral health efficiently. Some disinfectants with good safety and low toxicity might be used as supplementary agents in oral nursing care. Conclusions Oral nursing care procedures have improved the efficiency of oral care. But the conclusion should be verified by more, well designed randomized controlled trials involving a collaborative multidiscipliary health care professionals. Oral nursing care practice needs to be evidence based.
