Estudio de la eficacia de la tecnica osteopatica de liberacion del hueso lagrimal sobre la obstruccion congenita del conducto nasolagrimal.


Objectives: Evaluate the efficacy of Lacrimalis bones release osteopathic technique in children with congenital nasolagrimal duct obstruction (CNLDO).

Hypothesis: Lacrimalis bones release osteopathic technique by C. Rod de Vercher D.O. is effective for the congenital nasolagrimal duct obstruction.

Material and method: Randomized, simple-blinded, controlled experimental trial. Both sexes 2 weeks to 9 months age thirty children (30) with CNLDO were randomly distributed in two groups. Totally we studied 36 eyes. Intervention group received only one treatment and control group received a placebo treatment. We accept as indicators to value our efficacy the fluorescein disappearance test (FDT) and the modified Jones test (Jones). In both groups we have realized the FDT and the Jones before treatment (FDT1/Jones1), immediately after treatment (FDT2/Jones2) and 14 days before the treatment.

Results: In the intervention group we obtained some values of FDT2 (1´68±0´58) and FDT3 (1,474 ± 0,513) significantly smaller than placebo group (p<0´05). We obtained statistical association (p<0´005) between Jones2/positive and osteopathic treatment but no association between Jones3/positive and osteopathic treatment. Conclusions: Lacrimalis bones release osteopathic technique produce smaller values in group intervention FDT and more Jones positives just finished the treatment. Perhaps this efficacy increase with more than one treatment.
