This study introduces a new anatomical classification for orbital exenteration defects, improving reconstruction planning. The system offers a more precise description, enhancing surgical success rates for orbital tumors.
Area of Science:
- Ophthalmology
- Surgical Oncology
- Plastic and Reconstructive Surgery
Background:
- Orbital exenteration is performed for malignant tumors, resulting in diverse defects requiring specific reconstruction.
- Current defect classifications are inadequate for detailed description.
- This study proposes a novel anatomical classification system for orbital exenteration defects.
Purpose of the Study:
- To develop and validate a more effective anatomical classification system for orbital exenteration defects.
- To provide a detailed description of defects to guide reconstruction strategies.
Main Methods:
- Reviewed 50 orbital exenteration defects in 47 patients over 15 years.
- Categorized defects based on resected orbital wall, dura, and ethmoid resection.
- Classified maxillectomy involvement (partial/total) and identified 4 main defect patterns.
Main Results:
- No major complications, with minor wound-healing issues in 7 patients.
- 19% of patients used prosthesis, 46.8% used a patch.
- 16 patients could not use prostheses due to reconstruction methods.
Conclusions:
- The proposed anatomical classification system offers a more precise description of orbital exenteration defects.
- This enhanced description is expected to improve the success rates of both orbital reconstruction and tumor resection.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
