Quad Zygoma: A Graftless Solution in Post-mucormycosis Maxillectomy

Area of Science:

• Oral and Maxillofacial Surgery
• Dental Implantology
• Reconstructive Surgery

Background:

• Mucormycosis, a severe fungal infection, often necessitates extensive surgical removal of the maxilla, leading to significant defects.
• Reconstructing these defects is challenging, with traditional methods like flaps and bone grafts having limitations in providing structural support and osseointegration.
• Zygomatic implants have emerged as a promising alternative for complex maxillary reconstructions.

Observation:

• This case report focuses on the rehabilitation of post-mucormycosis patients using the quad zygomatic implant technique.
• The quad zygoma approach utilizes zygomatic implants for immediate prosthesis loading and eliminates the need for secondary procedures.
• Clinical outcomes were evaluated over two years, assessing soft tissue recovery, infection, prosthesis stability, and functional and aesthetic results.

Findings:

• The quad zygomatic implant technique demonstrated a high success rate in rehabilitating patients with post-mucormycosis maxillary defects.
• No significant complications were observed during the follow-up period, indicating the safety and efficacy of the procedure.
• Patients experienced improved eating effectiveness and aesthetic outcomes, highlighting the functional benefits of this reconstructive method.

Implications:

• The quad zygomatic implant technique represents a potentially novel gold-standard for treating compromised maxillas, offering advantages over traditional bone grafting.
• This approach simplifies treatment, reduces costs, and shortens the overall rehabilitation timeline for patients.
• The findings support the viability and effectiveness of quad zygomatic implants as a definitive solution for complex maxillary reconstruction post-mucormycosis.
