When the maxillary tuberosity fractures during the extraction of a third molar but remains attached, the appropriate approach is to leave it in place and stabilize if necessary. This approach is based on the understanding that the maxillary tuberosity is part of the maxilla and provides support to the structure of the upper jaw. If the fragment remains attached, it is likely still receiving blood supply and maintaining its viability.

Stabilizing the tuberosity can be achieved without removing it, thereby preserving the anatomical continuity of the jaw and minimizing additional trauma to the surrounding tissues. This approach helps in the healing process and reduces complications such as alveolar ridge resorption or disruption of the occlusion.

In contrast, removal and suturing of the tuberosity, filling the defect with Gelfoam, or excising the fragment could lead to unnecessary complications, including loss of structural integrity, increased healing time, and the potential for prolonged postoperative issues. Therefore, stabilizing the attached fragment is the most conservative and beneficial approach in this scenario.
