Brief Summary

Surgical ablation of large maxillary cysts usually results in considerable hard and soft tissue deficits that ultimately affect the final esthetic and functional outcomes. Reconstruction of such defects; whether primarily or secondarily; offers much better long-term outcomes. However, primary bony reconstruction becomes potentially complicated in many cases of such large cysts encroaching or involving the maxillary sinus where a communication with the maxillary sinus lining may be unavoidable. Reconstruction of such defects can be accomplished using either vascularized or; more commonly; non-vascularized autogenous bone grafts. Different bone substitutes remain to be another viable option. The simultaneous use of titanium meshes provides physical three-dimensional support for the bone graft contained within as well as the overlying soft tissues. However, the drawbacks of titanium meshes in such defects remain to be mainly the difficulty in adequately shaping the mesh and the lack of proper isolation of the mesh contents from the maxillary sinus cavity.

Eligibility Criteria

Age15 Years - 60 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Age of patients from 15 to 60 years old.
  • Patients with unilateral maxillary lesion encroaching maxillary sinus.
  • Dentulous or edentulous patients.
  • Patients should be free from any systemic disease that may affect normal healing of bone and predictable outcome.

You may not qualify if:

  • Patients with systemic diseases as history of radiation therapy or chemotherapy, hematological disorders, neuromotor disorders and autoimmune diseases (may affect normal healing).
  • Patients with bilateral maxillary lesions.
  • Children under 15 years old.
