ABSTRACT
Objective@#To explore a method for macrostomia repairment, in order to to achieve better physiological and aesthetic outcomes.@*Methods@#23 patients with macrostomia were treated by standard procedure: including orbicularis oris reconstruction, perioral expression muscles fixation, modiolus reconstruction, commissure point shift, and " w" shape incision.@*Results@#22 cases obtained both static and dynamic symmetrical outcomes. One case developed asymmetrically.@*Conclusions@#The macrostomia repairment following present standard procedure, is likely to achieve both static and dynamic satisfactory outcomes, due to balanced perioral muscles.
ABSTRACT
Competition of teaching skills is regarded as an effective means to develop teacher's ability in teaching.This article briefly described a teaching competition at a medical school from participant identification,requirement clarification,training before competition,evaluation index screening and interviewer selection.Meanwhile the article further analyzed and analyzed the problems arising from the competition and proposed measures to promote teachers' awareness and ability of teaching.
ABSTRACT
This study analyzes the reason and situation of the educational inspection for colleges and universities.The author suggests the five points to solve these problems and provide countermeasures for improving the educational inspection.
ABSTRACT
Objective To evaluate the therapeutic efficiency of reversed lamellar keratoplasty for bullous keratopathy, Terrien's marginal degeneration and ocular chemical burns.Methods Twenty eyes of patients with bullous keratopathy, twelve eyes with Terrien's marginal degeneration, ten eyes with chemical burns were recruited in this study.Diseased tissues were removed by means of dissection.Reversed lamellae corneal tissues which had been prepared by cryopreservation were thawed and rinsed. Then the prepared posterior corneal lamellae was turned over, endothelium facing upwards. The diameter of the graft should be 0.5～1.0mm larger than that of the recipient bed. The reversed donor posterior lamellae was sutured into the host keratectomy bed with 10-0 nylon sutures continuously or interruptedly.Results Allograft reaction episode occurred only one (chemical burn) of the total 42 eyes enrolled.The grafts of the rest 41 eyes maintained clear or semitransparent for 1～5 years. Graft edema could be observed within 2～4 weeks postoperatively. Postoperative interface separation was not found. For all 20 patients with bullous keratopathy, the symptoms of pain disappeared. The visual acuity improved 2～3 lines of Snellen among eleven of twelve patients with Terrien's marginal degeneration. The visual acuity improved 2～3 lines of Snellen with four patients with chemical burns.Conclusion The technique of reversed lamellar keratoplasty can be applied successfully for tectonic reconstruction of corneal surface such as bullous keratopathy, Terrien' s marginal degeneration and also chemical burns.The effects of therapy was satisfactory.
