AIM: We present a neonate with anomalous origin of the right pulmonary artery from the aorta and discuss the surgical technique and complications in the literature.
METHODS: A prospective study was conducted to evaluate the outcome of a new reconstruction technique that produces patient-specific hybrid polymethyl methacrylate-autologous cranial implant. Computer-assisted 3D modeling and printing was utilized to produce patient-specific molds, which allowed real-time reconstruction of bone flap with partial defect intra-operatively.
RESULTS: Outcome assessment for 11 patients at 6 weeks and 3 months post-operatively revealed satisfactory implant alignment with favorable cosmesis. The mean visual analog scale for cosmesis was 91. Mean implant size was 50cm, and the mean duration of intra-operative reconstruction was 30 minutes. All of them revealed improvement in quality of life following surgery as measured by the SF-36 score. Cost analysis revealed that this technique is more cost-effective compared to customized cranial prosthesis.
CONCLUSION: This new technique and approach produce hybrid autologous-alloplastic bone flap that resulted in satisfactory implant alignment and favorable cosmetic outcome with relatively low costs.
Methods: We described three different surgical techniques for correction of penile paraffinoma based on our single-centre experience. Informed consents were obtained from patients whose photographs were taken during the operation step.
Results: In general, three patients had simple excision biopsy with primary suturing, four patients underwent single stage excision of circumferential granuloma with bilateral scrotal skin flap reconstruction and one patient experienced dual stage procedure. Three of them were injected with paraffin, one with silicone and the remaining four were unable to identify the substance used. All patients successfully underwent the surgical procedure and four of them had minor post-operative surgical site infection and wound gapping.
Conclusion: All patients recovered well and the mean International Index of Erectile Function (IIEF-5) score obtained was 24.25. In our experience, excision biopsy was adequate for focal mass and reconstructive surgery using bilateral scrotal flap was suitable for circumferential mass.
DESIGN: Retrospective interventional case series.
METHODS: Thirty-nine eyes from 39 patients with a FTMH <600 μm were included from a single institution. All patients underwent vitrectomy using a semicircular single-layered ILM inverted flap assisted by a sub-perfluorocarbon liquid injection of ophthalmic viscoelastic device (OVD) technique. Best-corrected visual acuity (BCVA) and spectral domain optical coherence tomography were used to compare outcomes between nasal (n = 19) and temporal (n = 20) groups.
RESULTS: At 6 months postoperatively, all FTMHs closed and BCVA were significantly improved. Overall, 36 eyes (92%) achieved U-shaped closure, and ellipsoid zone restoration was noted in 24 eyes (62%). An ILM flap was present in 29 eyes (74%) and 86% remained single-layered. There were significantly more deep inner retinal dimples in the temporal group (35%) compared with 5% in the nasal group (P = .04), but these were unrelated to BCVA. Significant retinal thinning in the temporal outer sub-field was noted in the temporal group and was negatively correlated with BCVA (rho [ρ]: - .53; P = .03). No significant postoperative retinal displacement was noted in either group.
CONCLUSIONS: The technique of using sub-perfluorocarbon liquid injection of OVD secured single-layered flaps intraoperatively and postoperatively. Both the nasal and temporal inverted ILM flaps repaired FTMH and improved visual acuity. However, both temporal macular thinning and deep inner retinal dimples were significantly greater in the temporal group.
