Abstract:
A broken anesthetic needle is a rare complication in clinical practice. This article reports on 5 patients referred for removal of broken needles. The needles were located in the pterygomandibular space or near the maxillary tuberosity. These complications were the result of an unexpected movement by the patient or an incorrect anesthetic technique. The article also describes the case of a patient in whom an image observed in a routine panoramic radiograph could have been caused by a broken needle.
Insights
Broken anesthetic needles are rare but serious complications. This study reviews five cases of needle breakage during dental procedures, highlighting patient movement and technique as causes.
Area of Science:
- Dental Anesthesiology
- Oral and Maxillofacial Surgery
Background:
- Anesthetic needle breakage is an infrequent but significant complication in dental procedures.
- Prompt identification and management are crucial to prevent patient harm.
Observation:
- This article details five cases of broken anesthetic needles requiring surgical removal.
- Needles were lodged in the pterygomandibular space or near the maxillary tuberosity.
- A sixth case involved a suspected broken needle identified on a panoramic radiograph.
Findings:
- Patient's unexpected movements during anesthesia administration were a primary cause.
- Improper anesthetic technique was also identified as a contributing factor.
- Radiographic imaging is essential for diagnosing retained needle fragments.
Implications:
- Highlights the importance of meticulous anesthetic technique and patient cooperation.
- Underscores the need for vigilance in identifying and managing broken needle complications.
- Informs dental professionals on potential risks and diagnostic approaches for needle fragments.
