Technique for block anesthesia of maxillary nerve BAMNknown as the Carrea technique in South America is a local ambulatory anesthesia for use in dentistry.

The technique is described as the anesthesia administration in the pterygopalatine fossa of the skull, locating the greater palatine foramen in the palatal mucosa and subsequently inserting a needle into the greater palatine canal where the local anesthetic solution is deposited around the trunk of the maxillary nerve Methathrathip et al.

The greatest technical difficulty arises by the location of greater palatine foramen, bone accidents near or around the canal Suazo et al. There are those who define it as a very traumatic experience for the patient Malamed, ; Tima,as well as a complex technique given the potential to generate side effects such as diplopia by VIth cranial nerve pair anesthesia Malamed; Magliocca et al.

Several authors describe the technique as injection of 1. Achieving an optimal anesthetic effect is the ideal condition in clinical practice Coronado et al. This study allows us to extrapolate the required volume containing the bone cavity, thereby determining the minimum amount of anesthesia needed to achieve the anesthetic effect avoiding the risk of disseminating to other spaces of skull cavities.

With the information previously described, the aim of this pilot study is to compare the anesthetic efficacy between 1. A quasi-experimental exploratory pilot clinical study was carried fisa in patients selected from the Dental Emergency Services, in Valdivia, Chile, between May and September of We excluded patients requiring multiple pterigomaaxilar, pregnant female patients, those with a history of serious medical conditions, active sites of pathosis near injection site, or inability o give consent due to trismus, cases where pterigomailar view of greater palatine foramen was difficult, and those cases where is was not possible to reach location of greater palatine canal or complete needle penetration.

Chief dentist of Dental Services examined patients and determined clinical diagnosis.

Those patients who could be included in the study were encouraged to participate and were given the informed consent, pterigomaxilr approved a researcher recorded age, sex, cranial index, upper facial index and pterigkmaxilar of tooth to be extracted.

For cranial index, maximum anteroposterior skull length between the glabella and external occipital protuberance and maximum width of skull were measured, to match biparietal diameter. Cranial index was ptdrigomaxilar dividing transverse length by anteroposterior length multiplied by Subsequently we determined upper facial pferigomaxilar by dividing facial height by facial width and multiplying the quotient by For cranial and upper facial index we used an 8″ industrial caliper Mitutoyo, Japan.


Teeth were grouped into molars first, second or third pterigomaxxilarpremolars first or second premolar and anterior teeth canine and incisive. Anesthetic technique and procedure perfomance: The chief dentist of Emergency Services anesthetized the maxillary nerve using technique described by Malamed. Placing pterigomzxilar greater palatine foramen in the palatal mucosa projected by palpation with the blunt end of the dental mirror.

In the place where depression was located, the mucosa was punctured and penetrated the entire needle 27G 0. A second dentist evaluated the anesthetic effect after 15 minutes by syndesmotomy of the tooth to be extracted with a dental curve probe. Patient was asked to report pain intensity by visual analogue scale VAS.

After obtaining this information the emergency dentist extracted the tooth, defining anesthetic success AS as the possibility to perform tooth extraction pteeigomaxilar no pain or minimal pain, and defining anesthetic failure AF as pain being intolerable, in such cases dose was reinforced with 1. Pain intensity was pterigomaxioar during the extraction.

After extraction surgical site was conditioned and cleaned with saline solution 0. When necessary surgical wound was sutured with silk. Data were analyzed using Chi square test for dichotomous variables and T test for continuous variables with a statistical significance level of 0.

For recorded, tabulation and statistical analysis we used Stata Of the patients attended, complied with the selection criteria, of those, 57 patients refused to participate pterigomadilar personal reasons. Finally a study population of 82 patients with a mean age of Anesthetic success in LD group was Pain intensity in LD group was 2.

In all anesthetized patients, six 7. There were no other complications as acute pain or discomfort in palatal location nor the deposit of anesthesia in the pterygopalatine fossa. This pilot study found that maxillary nerve trunk block via greater palatine canal is possible in This study is based on suggestions made by Coronado et al.

The pterygopalatine fossa is comprised of maxillary nerve and pterygopalatine ganglion, pterygoid artery and vein, and connective tissue. Results show the feasibility of using reduced amounts of anesthesia to the previously required 1.

Diplopia was reported in 6 patients, 4 of the patients were administered 1. This could have been the result of diffusion of the anesthetic into the orbit through inferior orbital fissure pteriomaxilar VIth cranial nerve pair Mahoney; Malamed; Tima; Magliocca et al.

In the case of anesthesia through nostrils, anesthetic spreads through sphenopalatine foramen, which did not however result in greater patient discomfort. Patients reported no significant pain or rejection to the palatal puncture or anesthesia injection into the fossa. As Mahoney suggested this technique compared to infiltration technique extends the area for anesthesia for oral surgery. In the case of multiple maxillary tooth extractions it is more effective to block the trunk of maxillary nerve via greater palatine canal, than to administer multiple injections and painful palatal punctures.

This pilot study provided the basis for the feasibility of a randomized double blind clinical trial in which the dose studied pterigomxilar compared with that suggested by the authors previously mentioned. The study suggests integrating demographic variables and patient morphotype in a study model to obtain the most effective dose and lower complication rates.

The aim of this study is to compare the effectiveness of low doses of 1. Demographic pterigomaxliar and ageclinical tooth for extraction and anesthetic dose as well as anatomical variables upper facial and cranial index were recorded.

The anesthetic success AS was defined as the possibility to perform the tooth extraction with no pain or minimal pain as measured by visual analogue scale VAS.

Fosq results show that the pain and AS were pterigomaxliar. El objetivo del presente trabajo es comparar la eficacia de dosis bajas de 1,2ml DB versus dosis tradicional de 1,8ml DT de anestesia para el BTNM y sus efectos adversos.
