Area of Science:

  • Ophthalmology
  • Plastic Surgery
  • Biomaterials Engineering

Background:

  • Orbital reconstruction for hypo- and enophthalmos often relies on autogenous or alloplastic materials.
  • Donor-site morbidity and extended treatment times are significant drawbacks of traditional methods.
  • A novel technique utilizing titanium spacers was developed to mitigate these issues.

Purpose of the Study:

  • To evaluate the efficacy and safety of a new titanium spacer technique for orbital reconstruction.
  • To assess the impact of this technique on visual appearance and patient outcomes.
  • To compare complication rates with existing methods.

Main Methods:

  • A retrospective study of 29 patients treated with titanium spacers for orbital reconstruction between 2014 and 2018.
  • Assessed changes in deformity and visual appearance (0-3 scale), binocular vision, and complications.
  • Statistical analysis included descriptive statistics and the Mann-Whitney rank sum test (P<0.05).

Main Results:

  • Postoperative results were comparable to established literature.
  • Significant improvement in visual appearance (P<0.001) was observed, with decreased overall visual deformity.
  • Approximately 25% of patients had residual visual deformity, and complication rates were comparable to other methods.

Conclusions:

  • The titanium spacer technique is an effective and safe procedure for correcting hypo- and enophthalmos.
  • This method significantly minimizes donor-side morbidity and reduces overall treatment time.
  • The technique offers comparable outcomes to existing methods with added benefits of reduced morbidity and time.
