Sathya Kumar Devireddy M. Senthil Murugan R. V. Kishore Kumar Rajasekhar Gali Sridhar Reddy Kanubaddy M. Sunayana 《Journal of maxillofacial and oral surgery》2015,14(2):299-307
Introduction
Functional and cosmetic defects in maxillofacial region are caused by various ailments like trauma, neoplasm, developmental, infections and iatrogenic causes. Reconstruction of these defects with free flaps remains the gold standard but demerits like need for surgical expertise and equipment, prolonged duration of surgery, compliance of the patient and increased cost are associated with microvascular reconstruction. Hence reconstruction with nonvascular bone grafts can be considered when defect is nonirradiated and <9 cm and with sufficient soft tissue cover available.Purpose
To retrospectively evaluate clinical, radiological outcome and complications encountered with mandibular reconstruction using non vascular fibula graft.Patients and Methods
This retrospective study included 7 patients who were treated in the Department of Oral and Maxillofacial Surgery, Narayana Dental College and Hospital, Nellore, AP between 2011 and 2013 with histologically proven benign osteolytic lesions of mandible that require a segmental mandibulectomy and primary reconstruction using autogenous non-vascularised fibular graft. The clinical case records of the patients and personal patient assessment forms (Quality of Life Assessment Forms) were analysed. They were recalled every 3rd, 6th and 9th month after surgery for evaluation of clinical, radiological outcome of the graft and complications occurring at recipient and donor sites.Results
In all the 7 patients, the lower border continuity was maintained except in one where the graft was dislodged. Tongue movements in all the patients were unrestricted. Jaw movements were affected in cases of ramus defects with slight deviation to operated side and reduced mouth opening. Radiological observations revealed no significant changes in 3 months except for slight reduction in graft height. The radioopaque bridging with continuity of lower border of mandible was noticed in 6th month indicating the take of the graft. This was achieved in every case except in one where the graft was lost due to dislodged reconstruction plate. In 9th month the edges of the graft i.e., graft to native mandible junction showed more resorption (3 mm) especially where there is >2 mm of gap. Whereas increase in height of graft in other areas especially in graft to graft junction was seen. Significant graft resorption was seen in two cases. There were no major complications associated with the donor site.Conclusion
Avascular fibula graft although a second choice to vascularised fibula, is a favourable option for mandible defects of 6–10 cm under optimum conditions especially in developing countries where financial and/or surgical resources are limited. An attempt for primary reconstruction with this is never futile as it prevents aesthetic deformity even in the event of failure and thus makes secondary reconstruction easy. However in order to confirm the results a prospective study with large scale of patients is necessary.Electronic supplementary material

This longitudinal study assessed the role of early sleep patterns in predicting attention regulation and behavior problems. Sleep of 43 infants was assessed using actigraphy at 12 months of age and then reassessed when the children were 3–4 years old. During this follow-up, their attention regulation and behavior problems were also assessed using a computerized test and parental reports. Lower quality of sleep in infancy significantly predicted compromised attention regulation and behavior problems. These findings underscore the need to identify and treat early sleep problems. 相似文献

PURPOSE: The aim of this study was to assess the baseline computed tomography (CT) attenuation of acute and chronic pulmonary thromboemboli, their contrast enhancement (CE), correlation with haematocrit (Ht) levels and the presence of hypertrophic bronchial arteries. MATERIALS AND METHODS: From January 2006 to October 2009, we measured the baseline and postcontrast attenuation values of acute pulmonary thrombi emboli on CT angiograms of 86 patients with acute pulmonary embolism (PE) and those of chronic thrombi in 29 patients with pulmonary hypertension of various origins. The attenuation of acute thrombi was correlated with Ht and CE of chronic thrombi with the presence of hypertrophic bronchial arteries. RESULTS: Acute emboli had a mean baseline attenuation of 54.9 Hounsfield units (HU) and showed no CE. The attenuation of acute thrombi was not dependent on Ht. Chronic thrombi had a mean baseline attenuation of 33.8 HU, and 54% of thrombi showed significant CE. In 57% of cases, a collateral circulation had developed. In 76.5% of cases, CE and hypertrophic bronchial arteries coexisted (p=0.026). Neither thrombotic CE nor bronchial artery hypertrophy predominated in any one of the diseases associated with chronic thrombosis. CONCLUSIONS: Before contrast administration, acute emboli coare prevalently hyperattenuating and therefore more conspicuous. Only chronic thrombi exhibit CE, and CE is significantly associated with the development of collateral circulation, which may be involved in the process of thrombotic recanalisation. 相似文献

Three cases of fracture of a Carpentier-Edwards ring in tricuspid position are presented. In all three cases the shape of the ring was shown to be abnormal by roentgenogram examination; there was an abrupt bend in the middle portion of each ring. At the time of operation, fracture of the ring skeleton at this midpoint was found in all three instances. Roentgenogram examination seems to be a reliable method of diagnosing this uncommon entity, and tricuspid valve replacement is required for its correction. 相似文献

Hypnosis involves the manipulation of conscious attentional discrimination. The prepulse inhibition (PPI) paradigm assesses primary unconscious information processing. We investigated the correlation between hypnotizability and PPI of the startle reflex. Forty-eight healthy subjects were evaluated with the Stanford Hypnotic Susceptibility Scale, Form C (SHSS:C) and acoustic PPI. Subjects were divided into low, medium, and high hypnotizable groups. The low-hypnotizable group showed a significantly higher inhibition of the startle response, at lead intervals 60 ms and 120 ms, than did the medium- and high-hypnotizable groups. We conclude that hypnotizability and PPI may be negatively correlated. These findings lend further support for the role of dopaminergic neurotransmission mechanisms in the determination of hypnotizability levels. 相似文献
