[Mandibular condyle ectomy for the treatment of comminuted condylar fracture].

PURPOSE: To investigate the feasibility and indication of condylectomy for treatment of comminuted fractures of the condyle above the neck. METHODS: Sixty-one patients with condylar fractures, treated between September 2007 and September 2011 were reviewed respectively. Among them, 30 underwent open reduction and internal fixation, 15 underwent conservative therapy, and 16 patients (18 sides) who had comminuted fractures of the condyle above the neck underwent condylectomy. All the patients were followed up for 5 to 48 months after treatment to evaluate the outcomes. RESULTS: Among the 16 patients with condylectomy, poor wound healing due to rejection of hemostatic gauze was noted in 1 patient, occlusal deviation occurred in 1 patient, mild mouth opening limitation happened in 1 patient, and anterior open bite was present in 1 patient. The other patients recovered well, without apparent discomfort, malocclusion and facial asymmetry. CONCLUSIONS: For patients with finished maxillofacial growth, condylectomy is a feasible and effective way for management of comminuted fractures of the condyle above the neck. Postoperative occlusal deviation, open bite and limited mouth opening can be corrected with further expectant treatment.

[Peripheral ameloblastoma in mandibular gingiva: Report of one case].

The ameloblastoma mainly occurs in the mandible, rarely seen in the soft tissues. This paper reported 1 case of mandibular gingival peripheral ameloblastoma, and discussed its treatment based on literature review.

[Clinical analysis of 193 patients with thickening and nodular port wine stains].

PURPOSE: The purpose of this study is to investigate the relation between age, gender and thickening and nodules in port wine stains(PWS) patients. METHODS: The gender and age of 193 cases with port wine stains were compared between those with flat, those with thickening, those with thickening and nodules, in 0-19, 20-year age group. SAS6012 software package was used for Fisher's exact test and Kruskal-Wallis test. RESULTS: There were 165 cases with flat (85.49%), 10 cases with thickening (5.18%), 18 cases with thickening and nodules (9.33%). Kruskal-Wallis test demonstrated significant difference between 2 age groups(P<0.01).There was an increase incidence of thickening, and thickening and nodule formation in 0-19, 20-year age group(P<0.01), but there was no gender difference between thickening and nodules.The data were analyzed by SAS6.12 Fisher's exact test and Kruskal-Wallis test. CONCLUSION: The incidence of thickening and nodule formation in PWS increase with age.

[Lip and cheek reconstruction with composite radial forearm-palmaris longus tendon flap].

PURPOSE: To investigate the value of functional reconstruction of the lip and cheek with composite radial forearm-palmaris longus tendon flap. METHODS: Composite radial forearm-palmaris longus tendon flap was used in 5 cases, the flap was folded for repair of oral mucosa and external skin, palmaris longus tendon and the remaining orbicularis muscles were sutured so that oral contour and function could be achieved. All the patients were followed up for at least 20 months. RESULTS: All 5 composite flaps survived well postoperatively. 6 months after reconstruction, the patients had good oral and facial contour; 10-12 months after surgery, the dynamic function of mouth opening and closing as well as mastication was recovered to normal. CONCLUSION: Composite radial forearm-palmaris longus tendon flap is reliable and thus recommended for functional reconstruction of the lip and cheek.

[Thyroid hormone level change in patients undergoing oral and maxillofacial surgery].

PURPOSE: To study the changes of thyroid hormone level in patients undergoing oral and maxillofacial surgery before and after operation, in order to provide some evidences for postoperative treatment and recovery. METHODS: 60 cases with oral and maxillofacial operations under general or local anesthesia were assayed by radioimmunoassay for hormone levels changes of T3 ,T4, r T3 and TSH in serum before operation and on the first, forth and seventh day after operation. SPSS10.0 software package was used for one way ANOVA. RESULTS: Compared to preoperative levels, T3, T4 and r T3 (P<0.01) as well as TSH (P<0.05) in patients receiving operations under general anesthesia on the first, forth and seventh day postoperatively decreased significantly, while the changes of thyroid hormone level in patients receiving operations under local anesthesia before and after operation were not significantly different. CONCLUSION: Thyroid hormone level change in patients who underwent oral and maxillofacial surgery may be related to the type of operation and anesthesia.
