Purpose: To compare the efficacy of inlay and onlay bone grafting techniques in terms of vertical bone formation and implant outcomes for correcting atrophic posterior mandibles.
Materials and Methods: Twenty surgical sites were assigned to two treatment groups, inlay and onlay, with iliac crest as donor site. After 3 to 4 months, 43 implants were placed and loaded 4 months later. The median follow up after loading was 18 months.
Results: For the inlay versus onlay group, median bone gain was 4.9 versus 6.5 mm ( p = .019), median bone resorption was 0.5 versus 2.75 mm ( p < .001), and median final vertical augmentation was 4.1 versus 4 mm ( p = .190). The implant survival rate was 100% in both groups, while the implant success rate was 90% versus 86.9% ( p = .190, not significant). A minor and major complication rate of 20% and 10%, respectively, for both groups was encountered.
Conclusions: Inlay results in less bone resorption and more predictable outcomes, but requires an experienced surgeon. In contrast, onlay results in greater bone resorption and requires a bone block graft oversized in height, but involves a shorter learning curve. Once implant placement has been carried out, the outcomes are similar for both procedures. 相似文献

Objective
To determine the feasibility and safety of simple extra-fascial trachelectomy plus pelvic lymphadenectomy in young patients affected by early stage cervical cancer.Methods
We have prospectively identified all patients with early-stage cervical cancer (stages IA2-IB1) referred to our department. Inclusion criteria were: age ≤ 38 years, strong desire to maintain fertility, FIGO stage ≤ IB1, tumor size < 2 cm, no LVSI, no evidence of nodal metastasis. Surgical technique included two steps: laparoscopic pelvic lymphadenectomy and vaginal simple extrafascial trachelectomy. Patients were followed up for oncological and obstetrical outcomes.Results
Fourteen patients were enrolled in the study. Median age was 32 years (range 28-37); histotype was squamous in 11/14 (79%) cases and adenocarcinoma in 3/14 cases (21%); FIGO stage was IA2 in 5/14 (36%) patients, IB1 in 9/14 (64%) patients; median tumor size was 17 mm (range 14-19); median operative time was 120 min (range 95-210). No severe intraoperative complications were recorded. Postoperative complications were observed in two patients. No recurrences were detected. One patient died for other disease. Eight patients became pregnant and 3 of them had a term delivery.Conclusion
Low risk early-cervical cancer patients could be safely treated by simple extrafascial trachelectomy in order to maintain fertility. More studies are needed to better define the role of conservative and ultraconservative surgical approaches (i.e. conization) in this setting, either for fertility purposes or to minimize surgical complications. 相似文献957.

Obstructive sleep apnoea syndrome is the periodic reduction or cessation of airflow during sleep together with daytime sleepiness. Its diagnosis requires polysomnographic evidence of 5 or more episodes of apnoea or hypopnoea/hour of sleep (apnoea/hypopnoea index, AHI). Volumetric 3-dimensional computed tomographic (CT) reconstruction enables the accurate measurement of the volume of the airway. Nasal continuous positive airway pressure (CPAP) is the conventional non-surgical treatment for patients with severe disease. Operations on the soft tissues that are currently available give success rates of only 40%-60%. Maxillomandibular advancement is currently the most effective craniofacial surgical technique for the treatment of obstructive sleep apnoea in adults. However, the appropriate distance for advancement has not been established. Expansion of the air-flow column volume did not result in an additional reduction in AHI, which raises the important issue of how much the maxillomandibular complex should be advanced to obtain an adequate reduction in AHI while avoiding the risks of overexpansion or underexpansion. We have shown that there is a significant linear relation between increased absolute upper airway volume after advancement and improvement in the AHI (p=0.013). However, increases in upper airway volume of 70% or more achieved no further reduction in the AHI, which suggests that the clinical improvement in AHI reaches a plateau, and renders further expansion unnecessary. This gives a new perspective to treatment based on the prediction of changes in volume, so the amount of sagittal advancement can be tailored in each case, which replaces the current standard of 1 cm. 相似文献
