Objective To explore the effect of free anterolateral thigh (ALT) perforator flap in the repairment of complex maxillary defects. Methods The clinical data of 51 patients undergoing the reconstruction of maxillary defects in ALT perforator flap between January 2013 and October 2016 in the Peking University Hospital of Stomatology were retrospectively analyzed. All the patients received ALT reconstruction during the maxillary tumor resection. Results Four patients had blood vessel crisis after surgery in 51 cases. Two cases were removed due to flap necrosis, and 49 cases survived with a satisfactory appearance and function, and the overall flap survival rate of 49 cases was 96.08 ％ (49/51). Conclusion ALT perforator flap provides an ideal reconstruction for complex maxillary defects with a well-restored function in the surgical ares which could avoid the facial asymmetry and contribute to the following treatment.

Objective: To investigate the prevalence and psychosocial characteristics in inpatients with head and neck cancer before surgery. Method: From September 2015 to December 2016, 237 consecutive inpatients with head and neck cancer who had been scheduled for surgery were prospectively enrolled in Department of Head and Neck Surgery of Shanxi Provincial Tumor Hospital. Mental health symptoms were systematically investigated using three psychological instruments: symptom checklist-90 (SCL-90), Zung self-rating anxiety scale (SAS) and Zung self-rating depression scale (SDS). SPSS 17.0 software was used to analyze the data. And he results of SCL-90, SAS and SDS were compared with the Chinese norm. For all statistical analyses, a P value <0.05 was considered statistically significant. Result: Of 237 patients, 228 (96.2%) completed all the questionnaire. The scores of SCL-90 (1.60±0.44), SAS (46.67±8.51)and SDS(47.50±11.43)in patients with head and neck cancer were significantly higher than those of Chinese norm (t=3.093, t=17.29, t=4.29 respectively and P=0.003, P=0.001, P=0.001 respectively). Positive proportion identified by three measure tools are 32.9%, 35.5% and 36.8% respectively. And 42 patients (18.4%) suffered from both anxiety and depression. The SCL-90 scores were significantly higher than those of the normal standard population, including dimension of somatization obsessive-compulsive, anxiety, hostility, phobic-anxiety and psychoticism (t=4.47, 3.04, 2.87, 2.58, 5.46, 4.15 respectively, all P<0.05). Conclusions This study offers important information regarding psychological status in inpatients with head and neck cancer before surgery. Identifying these patients using proper screening instrument is of great important clinical implications for the early detection, management, and reduction of the distress associated with head and neck cancer.
