Summary
A rare anesthesia needle fragment during third molar extraction caused facial cellulitis. Prompt surgical intervention and foreign body removal led to complete patient recovery, highlighting the importance of meticulous surgical technique.
Area of Science:
- Oral and Maxillofacial Surgery
- Anesthesiology
Background:
- Third molar extraction is a common oral surgery procedure with a known risk of infectious complications.
- Infectious complications following local anesthesia for third molar extraction are estimated at 3.6%.
Observation:
- A 39-year-old female developed significant facial and neck swelling post-extraction of teeth 28 and 38 under local anesthesia.
- Diagnosis revealed facial cellulitis caused by a retained anesthesia needle fragment in the sub-angulo-mandibular region.
- Surgical drainage and removal of the foreign body were performed under general anesthesia.
Findings:
- A retained anesthesia needle fragment was successfully removed from the sub-angulo-mandibular region.
- The patient experienced complete resolution of facial cellulitis and swelling one month after the procedure.
Implications:
- Breaking anesthesia needles during oral surgery is a rare but serious complication.
- Adherence to best practices in local anesthesia administration is crucial for preventing such incidents.
- Increased scrutiny of forensic regulations in dental and oral surgery necessitates careful procedural conduct.

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...
01:26Brain Abscess l: Introduction
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
01:16Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.

01:12Local Anesthetics: Adverse Effects
While local anesthetics are generally safe and well-tolerated, they can occasionally cause adverse effects that vary in severity. Local anesthetics can induce toxicity at two distinct levels. They can either produce local effects through direct contact with the neural elements or be absorbed into the bloodstream from the injection site, leading to systemic effects.
Once absorbed into the systemic circulation, local anesthetics can affect the organs that depend on the functioning of sodium...

01:25Endocarditis I: Introduction
Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...
01:22Bacterial Meningitis I: Introduction
Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
