For a biopsy of a lesion in the retromolar pad area, which nerve blocks are required for adequate anesthesia?

The retromolar pad region is innervated by two nerves: the inferior alveolar nerve (IAN) — which supplies the lingual and most buccal aspects of the lower posterior region — and the long buccal nerve (buccal nerve), which specifically supplies the buccal mucosa and gingiva posterior to the mental foramen, including the retromolar pad. For complete anesthesia of this region, both the IAN block and the long buccal nerve block must be administered. The mental nerve supplies only the labial mucosa anteriorly and would not provide coverage for the retromolar pad.
