The quality of life in orthognathic surgery: surgery first versus traditional orthognathic surgery evaluation.

BACKGROUND: This study aims to evaluate the differences in terms of Quality of life and the degree of satisfaction with the result obtained between the two groups of patients treated with the orthodontic first approach and surgery first approach, through administered questionnaires inserted in the post-operative phase. METHODS: A total of 40 patients who previously underwent orthognathic surgery were included in this study, 20 treated with the orthodontic first approach and 20 treated with the Surgery First Approach. The impact of orthognathic surgery on patients' quality of life was recorded through the administration of the OHIP-14 test, FACE-Q test scale and FACE-Q test. Comparison between the two groups was done using a nonparametric inferential statistical test, the Mann-Whitney U-test. RESULTS: The results showed no significant differences in terms of quality of life between the two groups. Patients treated with orthodontic first approach presented greater psychological distress and perceived their faces as unattractive. CONCLUSIONS: A worsening of the aesthetics of the face determined by the orthodontic approach before surgery, may not be decisive in the quality of life of patients, which will certainly be better after surgery. SFA and OFA determine in both cases a marked improvement in the patient's quality of life.

Image-Guided Surgery in Complex Skull Base and Facial Fractures: Initial Experience on the Role of Intra-Operative Computer Tomography.

Surgery of fractures involving the skull base and the facial skeleton often presents challenges that should be addressed to prevent secondary brain injuries (i.e., cerebro-spinal fluid leak), preserve visual functioning, and guarantee a good esthetic result. Complex craniofacial reconstruction can be aided by navigation and pre-operative planning. In recent years, computerized planning of surgical reconstruction drastically increased the safety and efficacy of surgery, but the impact of intraoperative high quality image devices such as an intraoperative computed tomography (CT) scan has not been investigated yet. This case-control study reports the institutional preliminary experience of using intraoperative CT scans in the surgical management of complex cranio-facial fractures. The results in terms of accuracy of bony reconstruction and neurological or surgical complications have been analyzed in 12 consecutive patients treated with (6 cases) or without (6 cases) i-CT. Comparative analysis demonstrated a greater accuracy of reconstruction in patients treated with the assistance of i-CT. Intraoperative CT is a useful tool with a promising role in a multidisciplinary surgical approach to complex cranio-facial surgery.

A 3-Dimensional Evaluation of Bone Density in Alveolar Cleft Grafting Methods: Bone Substitutes Versus Autologous Bone.

INTRODUCTION: Secondary alveolar cleft repair using autologous bone graft is currently the gold standard in treating residual alveolar clefts. Despite its effectiveness, this technique is still burdened by several withdrawals, mostly related to donor site morbidity. To decrease disadvantages for patients, numerous attempts in the literature regarding bone substitutes have been described. The aim of this study is to compare the viability of bovine-based replacement bone material with respect of autologous bone graft in alveolar cleft reconstruction, through 3-dimensional alveolar cleft segmentation and bone density evaluation from preoperative and postoperative cone-beam computed tomography. PATIENTS AND METHODS: A retrospective cohort study of 10 patients who underwent surgical procedure for alveolar cleft grafting at Sant'Orsola Malpighi University Hospital of Bologna from December 2012 to December 2016 was undertaken. Five patients received autologous bone graft and 5 a bovine bone substitute graft. Preoperative and immediate postoperative orthopanoramic x-rays were recorded. Cone-beam computed tomography scans have recorded both pre and postoperatively. Volumetric evaluation on 3-dimensional cone-beam computed tomography images was performed. RESULTS: Alveolar clefts repaired using substitute bovine bone/biological membrane scaffold had a mean fill of 69.00% of total cleft volume, while this figure was of 67.07% with autologous bone grafting. The immediate postoperative course and subsequent discharge were uneventful for both groups, with a difference in timing. The cost of substitute bovine bone was offset by cost savings associated with a reduction in operative and postoperative and hospitalization time. CONCLUSIONS: Bone substitutes showed to be a promising solution in alveolar cleft grafting.
