Summary
A novel endoscopic technique successfully treated chronic rhinosinusitis (CRS) caused by zygomatic implants. This modified medial maxillectomy preserved oral function and improved sinus health.
Area of Science:
- Otolaryngology
- Oral and Maxillofacial Surgery
- Medical Devices
Background:
- Odontogenic chronic rhinosinusitis (CRS) is a significant clinical issue, often linked to dental procedures like zygomatic implantation.
- Current treatments for odontogenic CRS typically involve surgical removal of infected implants, either endoscopically or via open approaches.
Purpose of the Study:
- To present a novel management strategy for odontogenic CRS following bilateral zygomatic implantation.
- To describe a modified endoscopic medial maxillectomy technique for salvaging displaced zygomatic implants and treating associated sinusitis.
Main Methods:
- A case presentation detailing the development and management of bilateral CRS after zygomatic implantation.
- Surgical intervention using a modified endoscopic medial maxillectomy to address the sinusitis and preserve implant function.
Main Results:
- The patient experienced significant improvement in endoscopic, radiologic, and symptomatic outcomes.
- Sino-Nasal Outcome Test (22-item) scores indicated marked postoperative improvement.
Conclusions:
- A modified endoscopic medial maxillectomy offers a new treatment approach for odontogenic sinusitis secondary to zygomatic implantation.
- This technique allows for mucosal normalization within the affected sinus while preserving the displaced implant and oral function.
