ABSTRACT
Objective To investigate the application effect of APP in continuing care of discharged patients with condylar fracture after operation. Methods By convenience sampling,from September 2016 to March 2017 in a ward of oral and maxillofacial surgery and received surgical treatment of condylar fracture patients 81 cases, randomly divided into observation group (41 cases) and control group (40 cases).On the basis of routine health education,the observation group carried out continuous care by APP, while the control group received routine health education. The opening type, opening degree, occlusion relation and temporomandibular joint pain in two groups were compared at 6 months after discharge. Results The results of 6 months, the patients in the observation group were open type, occlusion and TMJ pain were better than the control group, the opening degree of the observation group was (35.51 ± 4.34) mm, control group was (31.28 ± 4.57) mm, the difference between the two groups was statistically significant(t=-4.28,P<0.05).There was no statistical difference between the two groups of occlusion and temporomandibular joint pain (P>0.05). Conclusions APP can improve the open type, opening and occlusal relation and temporomandibular joint pain in patients with condylar fracture after operation.
ABSTRACT
Objective To assess the efficacy of different internal fixations of palatal fracture.Methods Seventy-four patients with palatal fracture admitted between October 2007 and October 2013 were reviewed retrospectively.Through out-patient follow-up,postoperative occlusion and palatal complications were examined and fracture healing was evaluated using CT scan.Results Palatal type Ⅰ-Vfractures involved in 8 patients (11％),14 patients (19％),26 (35％),12 patients (16％),6 patients (8％),and 8 patients (11％) respectively.Forty-three patients were available to follow-up,including 31 patients with good or acceptable occlusion.All wounds healed without palate associated infections,plate exposure or oronasal fistula.Of the 27 patients classified as type Ⅱ,Ⅲ and V sagittal palatal fractures,both nasomaxillary and zygomatico-maxillary struts fixation (n =17) and isolated zygomatico-maxillary struts fixation (n =10) had insignificant differences in success rate as to occlusion assessment (82％ vs 80％,P ＞0.05).Whereas compared with isolated vertical buttress fixation (n =15),additional immobilization of horizontal alveolar buttresses (n =12) had significantly higher success rate (100％ vs 67％,P ＜ 0.05).Conclusion Complete rigid fixation at early stage,including vertical buttress fixation,in particular the zygomatico-maxillary struts,and horizontal alveolar buttress fixation can achieve satisfactory outcome.
ABSTRACT
Objective To investigate the application of MRI in evaluation of the traumatic temporomandibular joint (TMJ) injury induced by type Ⅵ condylar fracture. MethodsMRI was performed in TMJs in 18 patients with type Ⅵ condylar fractures at days 3-14 post-injury and the MRI findings were analyzed. ResultsMRI findings of 18 patients with traumatic TMJ injury with 19 sides of type Ⅵ condylar fractures showed 15 sides of TMJ disk displacement,nine sides of capsule tear,16 sides of retrodiscal tissue tear (double-plate area) and 19 sides of joint effusion change. Conclusions MRI is very important in the diagnosis and evaluation of traumatic TMJ injury,since it can clearly display the TMJ injuries in type Ⅵ condylar fractures.Therefore,the clinical application of MRI is beneficial for selection of the therapeutic schedules.
