An Unusual Maxillary Sinus Foreign Body: A Case Report

BACKGROUND Paranasal sinus foreign bodies are rarely encountered in otolaryngology practice. CASE REPORT We present the case of a 32-year-old man who presented to our Emergency Department with his left eye bleeding after a nail gun injury. The initial physical examination revealed the presence of a left eye ruptured globe, which led to left eye blindness. An urgent plain X-ray scan was done, in which the presence of a metallic object impacted in the left maxillary sinus was demonstrated. The patient was managed surgically by an external approach using the Caldwell-Luc procedure, with no intra- or postoperative complications. CONCLUSIONS Paranasal sinus foreign bodies, if improperly treated, can cause serious morbidity. Surgical removal, either endoscopically or through an external approach, is required.

[Methods of maxillary sinus foreign bodies removal]

THE AIM

To characterize methods of extraction of foreign bodies of maxillary sinuses, features of postoperative treatment of patients.

MATERIAL AND METHODS

The experience of treatment of patients with maxillary sinuses foreign bodies in the clinic of ENT of PFSMU of St.Petersburg is presented. In 2019 124 patients undergo treatment of maxillary sinus foreign bodies in our clinic. All surgeries are done by endoscopic endonasal method, mostly via inferior nasal passage. Clinical case of maxillary sinus foreign body removal is presented.

RESULTS

Almost any kind of foreign body can be removed from the maxillary sinus endoscopically through the nasal cavity. The most reliable method to diagnose foreign body is computed tomography. In most cases local antibacterial therapy is enough in postoperative period.

An Unusual Pediatric Case of Allen Key Penetrating Trauma in Maxillofacial Region

Paranasal sinus (PNS) foreign bodies are not common. They are usually due to penetrating trauma and iatrogenic events. On imaging, radiopaque foreign bodies can easily be detected by X-ray views of PNS. CT scan may be necessary to evaluate the exact location of foreign body in some cases. Foreign body in the PNS should be removed as early as possible. Approach and technique of its removal depend upon its size, shape, and location. Nasal endoscopic examination can be helpful for these cases. We present a pediatric girl case of penetrating FB injury inserted into the maxillary sinus towards nasopharynx in a suddenly braking car.
