The “Scotch Tape” for Surgery: How a Kitchen-Table Invention is Saving Severed Nerves

by

For over a century, surgeons faced a frustrating reality: repairing a severed nerve was like trying to sew two wet pieces of spaghetti together using microscopic thread. Even with the most skilled hands, patients only had about a 50-50 chance of a full recovery. That “gold standard” just wasn’t good enough for Dr. Jonathan Isaacs, a surgeon-researcher at VCU Health. His solution? A tiny, suture-free wrap called Nerve Tape. The Problem with the “Gold Standard” When a peripheral nerve is severed—whether from a bad fall, a car accident, or during a complex surgery like a mastectomy—the standard treatment is suturing. Surgeons use incredibly fine needles to sew the delicate nerve ends back together. However, this method has major drawbacks: From Fishing Hooks to the Operating Room Dr. Isaacs’ journey to revolutionize surgery didn’t start in a high-tech lab—it started at … Read more

Dentists increasingly use articaine 

by

An interesting article titled “Survey investigation of articaine use in the United States,” written by Robert D. Bowers and et. al. appears in the the Journal of the American Dental Association (published Oct. 2023). The article conducted a study to expand the knowledge of local anesthesia practices of dentists in the U.S. with a specific focus on influencing factors regarding articaine. The U.S. Food and Drug Administration approved the use of articaine in 2000 and dental use of articaine has grown over the years. In 2017, it was estimated that estimate about 40% of the total U.S. dental local anesthetic market was for articaine. However, articaine has a 4% concentration which has led some to question its safety. Past studies have shown that higher concentrated local anesthetics like articaine can lead to increased risk of dental paresthesia. To study the use … Read more

Wisdom Teeth Removal Can Improve Long Term Taste

by

Interesting research appears in the article “Positive Long-Term Effects of Third Molar Extraction on Taste Function,” by Dane Kim and Richard L. Doty appears in Chemical Senses, v.ol 46, pp. 1-5, 2021. The article discusses how patients in the study had improved tasting ability decades after having wisdom teeth removed. This is counter to prior studies that have adverse effects on taste after having wisdom teeth extracted which was believed to dissipate over time. In the article the researchers evaluated data from 1,255 patients who had undergone a chemosensory evaluation at the University of Pennslyvania’s Smell and Taste Center over the course of 20 years. From this group of patients, 891 patients had received wisdom teeth (third molar) extractions and 364 had not. All participants were asked to complete a sip-and-spit whole-mouth taste test with five different concentrations of sucrose, … Read more

Chances of Nerve Injury After Wisdom Teeth Removal

by

An interesting article titled “Investigation of nerve injury after lower third molar removal” written by Moosa and Malden appears in the 2018 edition of Oral Surgery (vol. 11, pp. 22-27). The article seeks to address how many patients develop inferior alveolar nerve or lingual nerve injury after wisdom teeth removal at a dental clinic in Edinburgh, UK. Nerve injury is a type of complication that is known to occur after wisdom teeth removal. Two nerves that are often damaged include the inferior alveolar nerve and the lingual nerve. When the inferior alveolar nerve is injured there can be tingling, numbness, burning, or painful sensations near the lower lip, chin, and teeth. When the lingual nerve is injured there can be tingling, numbness, burning, or painful sensations near the tongue and loss of taste can occur. According to the authors prior … Read more

Quality of Life Following Injury to the Inferior Alveolar Nerve or Lingual Nerve During Wisdom Teeth Surgery

by

An interesting article titled “Quality of life following injury to the inferior dental or lingual nerve – a cross-sectional mixed-methods study” written by Patel et al. appears in the 2018 edition of Oral Surgery (vol. 11, pp. 9-16). The article seeks to explore the impact of nerve damage that occurred during wisdom teeth removal on a persons quality of life. In the article the authors discuss how the most common reason for injury to either the inferior alveolar nerve or lingual nerve is wisdom teeth removal. Even so these types of injuries can also occur during other types of procedures such as anesthetic block injection and dental implant placement. There are different management options to deal with the nerve injury such as counselling, topical and systemic analgesia, or surgical intervention. Nerve injuries can result in altered sensation and/or pain and … Read more
