Using Computed Tomograph (CT) To Lower the Incidence of Wisdom Teeth Removal Nerve Injuries

by

A question that everyone who has wisdom teeth wants to know these days is the following: “If you use Computed Tomography (CT) can it lower the risk of developing a nerve injury from having wisdom teeth removed?” Three authors from Spain (Sanmarti-Garcia, Valmaseda0-Castellon, Gay-Escoda) recently conducted a study asking this question titled “Does Computed Tomography Prevent Inferior Alveolar Nerve Injuries Caused by Lower Third Molar Removal?” appearing in the Journal of Oral and Maxillofacial Surgery (vol 70, pages 5-11, 2012). The issue is as stated by the authors is that “panoramic radiography alone cannot identify the buccolingual position of the mandibular canal and the 3M roots.” Computed tomography (CT) is able to show this information. Even so an estimated 40% of cases show superposition of the roots and the mandibular canal. Hence many of the potential CTs performed may potentially … Read more

Long Term Effects of Trigeminal Nerve Injuries from Dental Care

by

A study was published in the Journal of Oral and Maxillofacial Surgery titled “Long-Term Outcome of Trigeminal Nerve Injuries Related to Dental Treatment” by M. Anthony Pogrel, Ryan Jergensen, Eric Burgon, and Daniel Hulme. (vol. 69, pages 2284-2288, 2011) that looked at long-term effects of those who suffer from permanent nerve injury from dental treatment particularly involving the third molars or wisdom teeth. A total of 145 patients with 95 female and 50 male patients were involved in the study who had suffered a trigeminal nerve injury affecting either the inferior alveolar nerve or lingual nerve and in 8 cases both nerves. Nineteen patients (13.1 %) reported that their employment was affected, while 21  patients (14.5%)  reported problems with their relationship, 53  patients (36. 6%) reported depression, 55  patients (38%) reported problems speaking and pronouncing words correctly, 63  patients (43.5%) reported … Read more

Surgical Treatment of Migraine Headaches

by

A study published in Plastic and Reconstructive Surgery shows that trigger site surgery may aid in reducing or even eliminating migraine headaches. 100 patients in a study underwent injection of botulinum toxin A (Botox) into up to 4 potential trigger sites. If a trigger site was identified to be effective than surgery was performed in that trigger area in order to decompress nerves and remove muscles. 71 of 79 patients that were evaluated over a 5 year period were observed to have improvement. This meant they had less mean migraine intensity and or less mean migraine duration. 20 of 69 patients (29.0%) reported elimination of migraines and 41 of 69 patients (59.4%) experience a significant decrease. Surgery is not without risk and neither is injection of botulinum toxin A.  2 patients had hypersensitivity, 2 patients had hyposensitivity, and 2 patients … Read more
