Chronic Maxillary Sinusitis Caused by Denture Lining Material.

Area of Science:

• Otorhinolaryngology
• Oral and Maxillofacial Surgery
• Medical Device Complications

Background:

• Chronic maxillary sinusitis can arise from various causes, including foreign body obstruction.
• Oroantral fistulas, often resulting from dental procedures, create a pathway for foreign material into the maxillary sinus.

Purpose of the Study:

• To report a unique case of chronic maxillary sinusitis caused by a migrated silicone denture lining material.
• To describe the successful endoscopic surgical management of this condition.

Main Methods:

• A case presentation of an 80-year-old female with symptoms of sinusitis and purulent discharge.
• Diagnostic imaging including computed tomography (CT) to identify a foreign body within the maxillary sinus.
• Endoscopic maxillary surgery for foreign body removal and management of sinusitis.

Main Results:

• A 12x6 mm oval, light pink foreign body, identified as silicone denture lining material, was removed from the right maxillary sinus.
• The patient's chronic maxillary sinusitis resolved post-operatively.
• The oroantral fistula closed spontaneously within the follow-up period.

Conclusions:

• Silicone denture lining material can cause chronic maxillary sinusitis if introduced into the sinus via an oroantral fistula.
• Endoscopic surgery is an effective treatment for foreign body-induced maxillary sinusitis.
• Spontaneous closure of oroantral fistulas can occur after foreign body removal.
