Endoscopic-Assisted Trans-Posterolateral Maxillary Sinus Wall Approach for Extracting the Maxillary Third Molar Displaced Into the Maxillary Sinus

The accidental displacement of maxillary third molars into the maxillary sinus is a relatively rare occurrence that may result in sinusitis, subsequently leading to symptoms such as facial swelling, pain, and nasal obstruction. For larger foreign bodies, traditional surgical approaches may have limitations and can potentially result in complications. This study reports the successful extraction of third molars displaced into the maxillary sinus using an endoscope-assisted, posterior lateral wall approach, achieving favorable clinical outcomes.
