Summary
A novel curved needle technique for the posterior superior alveolar nerve (PSAN) block provides effective anesthesia for maxillary molars with no reported complications. This simplified approach enhances dental anesthesia safety and reliability.
Area of Science:
- Dentistry
- Anesthesiology
- Oral and Maxillofacial Surgery
Background:
- The posterior superior alveolar nerve (PSAN) block is crucial for maxillary molar anesthesia.
- Traditional PSAN block techniques face challenges due to unreliable landmarks and frequent complications.
- A need exists for a simplified, complication-free PSAN block method.
Purpose of the Study:
- To develop and evaluate a technically simple and complication-free method for the posterior superior alveolar nerve (PSAN) block.
- To improve the reliability and safety of anesthesia for maxillary molar procedures.
Main Methods:
- The study involved 200 patients (125 males, 75 females, aged 20-65).
- A modified PSAN block technique using a curved needle was employed.
- Data collected on anesthesia efficacy and complications.
Main Results:
- Successful anesthesia was achieved in all 200 patients within 5-10 minutes.
- No visual complications were reported during or after the procedure.
- Patients experienced no pain during or after tooth extraction.
Conclusions:
- The modified PSAN block using a curved needle effectively avoids complications associated with traditional techniques.
- This simplified technique offers an ideal and safe option for anesthetizing the PSA nerve.
- The study highlights the potential of this modified approach for routine dental practice.

2.1K
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.

Depending on the target organ, local anesthetics (LAs) can be administered via various routes. In surface anesthesia, LAs are applied directly to the surface of the skin or mucous membranes. It is widely used for topical skin numbing before venipuncture or minor surgical procedures. Commonly used surface local anesthetics are lidocaine or benzocaine sprays or creams. Surface anesthesia occurs within 5 minutes and lasts for about 60 minutes. One of the main disadvantages of topical anesthesia is...

2.0K
Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...

1.7K
Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...

Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

Local anesthetics (LAs) block sensory and motor impulses by inhibiting the sodium channels on the nerve cell membranes. This induces temporary loss of sensation, relieving pain in a specific body area.
Local anesthetics are amphiphilic molecules consisting of a hydrophobic aromatic part linked to a hydrophilic group by an ester or amide linkage. They are weak bases and are usually available as salts, which increases their solubility and stability. Once administered, LAs exist in the body either...
