Comparison of different positioning techniques for reduction of induced vertical deviation following Nishida procedure for the treatment of sixth nerve palsy.
Purpose: Induced vertical deviation is a potential complication following the Nishida procedure for the treatment of sixth nerve palsy. This study aims to compare different positioning techniques for the reduction of this complication.
Methods: We retrospectively examined medical records from consecutive patients who underwent the Nishida procedure, classifying them into three positioning groups: intra-quadrant (IQP), lateral rectus border (LRBP), and horizontal meridian (HMP). Surgical and pre/postoperative data were compared.
Results: Among the 27 included patients (8 IQP, 9 LRBP, 10 HMP), all three groups demonstrated similar reductions in esodeviation: IQP, 44.0 ± 18.7 Prism Diopters (PD); LRBP, 42.2 ± 15.3 PD; HMP, 42.2 ± 7.8 PD; (P = 0.675). After surgery, one patient in the IQP group developed hypertropia of 18 PD, necessitating a secondary surgery to treat the vertical diplopia. In the LRBP group, two patients had hypotropia of 30 PD and 10 PD, respectively, and one patient had hypertropia of 6 PD. In the HMP group, one patient initially had hypertropia of 2 PD, which resolved during subsequent follow-up. A lower incidence of induced vertical deviation was observed in the HMP (10%) and IQP (13%) groups compared to the LRBP group (33%). However, this difference did not reach statistical significance due to the small sample size.
Conclusion: There is no statistically significant difference among the three positioning techniques (IQP, LRBP, HMP) in the correction of esodeviation and reduction of incidence of induced vertical deviation following Nishida procedure.
