Damage of a dental needle during local anesthesia is very rare complication nowadays. We present such an occurrence in which the needle was lost in the pterygomandibular space during routine dental practice. Patient was referred to Oral & Maxillofacial surgery department where he was treated and the needle was removed. Postoperative period was uneventful. We attribute this to the utility of Cone Beam Computed Imaging that made the exact locating of the needle in the soft tissues possible. We underline the significance of CBCT to precisely locate the broken needle and to facilitate its surgical retrieval.
