Here, we present a description of the surgical techniques used in a Nigerian teaching hospital and a preliminary report of the first five cases of adult alveolar cleft bone grafting accomplished with or without repositioning the premaxilla. Although, evidence of bone resorption was observed within 6 months after the operation, satisfactory bone level and aesthetic outcome was recorded in all cases. We concluded that tertiary alveolar bone grafting is desirable for all cases where alveolar clefts have persisted into adulthood to enhance the psyche of the cleft patients and to motivate them for further rehabilitation. Prompt placement of dental implant into the grafted area is recommended to mitigate subsequent resorption of the bone graft.展开更多

Design: Retrospective non-comparative case series. Participants: Twenty five high-risk patients undergoing DSAEK at one tertiary care institution. Methods: A retrospective evaluation of consecutively enrolled high-risk DSAEK cases performed by three surgeons at one institution during a 3-year period (2007-2010). Main outcome measures were graft adherence and suture-related complications. Results: Highrisk factors were defined as followed: prior incisional glaucoma surgery (58%), presence of vitreous in the anterior chamber (15%), anterior chamber intraocular lens (8%), graft dislocation (8%), previous DSAEK (8%), and iris trauma/aphakia (3%). Twenty-five high-risk patients underwent DSAEK with Y-suture transfixation. Postoperative follow-up ranged from 3 to 27 months. One patient had dislocation due to hypotony from prior trabeculectomy (4%), requiring repeat DSAEK. Neither primary graft failure nor suture-related complication was observed. Conclusion: The Y-suture transfixation technique is associated with improved success rate of high-risk DSAEK transplant.展开更多

They are often overlooked during the initial examination and delayed diagnosis adversely affects healing process. Apart from many open treatment options, there are reports of single attempts to treat such cases arthroscopically. Purpose: We present an original case of a posterior locked dislocation of the shoulder joint with a fracture of the lesser tuberosity followed by reverse Hill-Sachs fracture, treated in a novel fashion all-arthroscopically with the use of allogenic bone graft. Method: According to Constant Shoulder Score that tries to assess functional and subjective performance of the shoulder joint before the operation and after 12 months, we achieved a leap from 11 to 84. Results: The patient restored almost full range of motion and painless movement in activities of daily life as well as during sports. Conclusion: The use of an arthroscope reduces the invasiveness of the procedure, improves visualization of the joint and allows augmentation of the bone loss without performing an open approach. We believe that this is a promising method of treatment for selected cases of locked posterior shoulder dislocation.展开更多

Possible predisposing risk factors and some characteristics of late in-the-bag spontaneous IOL dislocations;outcomes of IOL repositioning and exchange surgeries, including visual acuity, refractive status before and after surgery and postoperative complications were evaluated.RESULTS: The predisposing factors for late in-the-bag spontaneous IOL dislocations were pseudoexfoliation [PEX;12/39(30.8%)], previous vitreoretinal surgery [7/39(17.9%)], axial myopia [3/39(7.7%)], both PEX and axial myopia [1/39(2.6%)], both previous vitreoretinal surgery and axial myopia [2/39(5.1%)] and uveitis (1/39(2.6%))The mean interval between cataract and dislocation surgery was 7.23 y, greater in PEX positive group(8.63 y). The mean best corrected visual acuity(BCVA) improved significantly after dislocation surgery(P<0.001) and also improved significantly after exchange surgery(P=0.001). The mean value of spherical equivalant decreased significantly after dislocation surgery(P=0.011), whereas corneal astigmatism increased but this difference was not significant after dislocation surgery and exchange surgery(P=0.191, P=0.074, respectively).CONCLUSION: The most prevelant risk factors for late inthe-bag spontaneous IOL dislocations are PEX, previous vitreoretinal surgery and axial myopia. In the management of IOL dislocations, exchange surgery with small corneal incision seemed effective with improved BCVA and safety with low postoperative complications.展开更多

文摘Objective：To report surgical management and favorable outcome in a case with delayed repair of traumatic laser in situ keratomileusis（LASIK）flap dislocation with shrinkage and folds.Methods：A 30-year-old man with a five-year history of bilateral LASIK experienced blunt trauma to his right eye followed by decreased vision for 5 weeks.The surgical management included initially softening the flap by irrigation with balanced salt solution（BSS）.The shrinkage folds were carefully and gently stretched by scraping with a 26-gauge cannula accompanied by BSS irrigation.All of the epithelial ingrowth on the flap inner surface and on the bed was thoroughly debrided by scraping and irrigation.After the flap was repositioned to match its original margin,a soft bandage contact lens was placed.Results：At his initial visit,slit-lamp microscopy and optical coherence tomography（OCT）showed shrinkage of the LASIK flap with an elevated margin approximately 3 mm above the original position.The flap covered half of the pupil and had multiple horizontal folds.Two months after surgery,the flap remained well positioned with only faint streaks in the anterior stroma.The uncorrected visual acuity of the right eye was 20/20 with a manifest refraction of Plano.Conclusions：For delayed repair of traumatically dislocated LASIK flaps,sufficient softening by BSS,stretching the shrinkage folds,and thorough debridement of ingrowth epithelium enable resetting the flap and provide satisfactory results.
文摘The outcome of alveolar bone grafting in adult patients is sparsely reported. Here, we present a description of the surgical techniques used in a Nigerian teaching hospital and a preliminary report of the first five cases of adult alveolar cleft bone grafting accomplished with or without repositioning the premaxilla. Although, evidence of bone resorption was observed within 6 months after the operation, satisfactory bone level and aesthetic outcome was recorded in all cases. We concluded that tertiary alveolar bone grafting is desirable for all cases where alveolar clefts have persisted into adulthood to enhance the psyche of the cleft patients and to motivate them for further rehabilitation. Prompt placement of dental implant into the grafted area is recommended to mitigate subsequent resorption of the bone graft.

Possible predisposing risk factors and some characteristics of late in-the-bag spontaneous IOL dislocations;outcomes of IOL repositioning and exchange surgeries, including visual acuity, refractive status before and after surgery and postoperative complications were evaluated.RESULTS: The predisposing factors for late in-the-bag spontaneous IOL dislocations were pseudoexfoliation [PEX;12/39(30.8%)], previous vitreoretinal surgery [7/39(17.9%)], axial myopia [3/39(7.7%)], both PEX and axial myopia [1/39(2.6%)], both previous vitreoretinal surgery and axial myopia [2/39(5.1%)] and uveitis (1/39(2.6%))The mean interval between cataract and dislocation surgery was 7.23 y, greater in PEX positive group(8.63 y). The mean best corrected visual acuity(BCVA) improved significantly after dislocation surgery(P<0.001) and also improved significantly after exchange surgery(P=0.001). The mean value of spherical equivalant decreased significantly after dislocation surgery(P=0.011), whereas corneal astigmatism increased but this difference was not significant after dislocation surgery and exchange surgery(P=0.191, P=0.074, respectively).CONCLUSION: The most prevelant risk factors for late inthe-bag spontaneous IOL dislocations are PEX, previous vitreoretinal surgery and axial myopia. In the management of IOL dislocations, exchange surgery with small corneal incision seemed effective with improved BCVA and safety with low postoperative complications.
