Zygoma resection
Considerations
Pathology
1992: Intraosseous hemangioma of the zygomatic bone. A case report
2001: Intraosseous Hemangioma of the Zygoma: CT and MR Findings
2012: Cavernous hemangioma--uncommon presentation in zygomatic bone
Approaches
Direct
Coronal
Pros
option for temporal or preauricular extension
excellent exposure of the zygomatic arch
allows reconstruction of the width and AP projection of the midface
Cons - often outweigh the pros
significant scar alopecia
temporal hollowing
possible risk of injury to the temporal branch of the facial nerve
Indirect
Temporal (Gillies)
Modified temporal
Transoral (Keen), i.e. lateral maxillary vestibular incision
Lower eyelid - transcutaneous
Lower eyelid transconjunctival
Superolateral orbital rim
Midface degloving
Weber-Ferguson
Lateral rhinotomy
Reconstruction
2010: Reconstruction of the maxilla and midface: introducing a new classification
Goals: Restore...
orbital volume,
width,
AP projection,
and height of the midface
3-point vs 4-point fixation
1st plate: frontozygomatic
2nd plate: orbital rim (3-point) vs zygomatic arch (4-point)
3rd plage: zygomaticomaxillary buttress (3-point) vs orbital rim (4-point)
4th plate: zygomaticomaxillary buttress
