TRUE MANDIBULAR BLOCK ANESTHESIA에 대한 임상 및 방사선학적 연구

TRUE MANDIBULAR BLOCK ANESTHESIA : A COMPARATIVE CLINICAL AND RADIOGRAPHIC STUDY

The purpose of this study is to compare the true mandibular block anesthesia with the inferior alveolar nerve block anesthesia in the clinical and radiographic aspects. Fifty persons for clinical evaluation and ten persons for radiographic evaluation were examined. For the clinical study, following factors are considered; position of the patient, depth of needle penetration, aspiration of blood, onset time of anesthesia, presence of long buccal nerve anesthesia, degree of anesthesia, soft tissue analgesia, duration of anesthesia, anesthetic complications. For the radiographic study, the distribution of the injected mixture of contrast media (telebrix) and local anesthetic agent (lidocaine hydrocholoride) was evaluated in 5 person with inferior alveolar nerve block technic and in 5 person with true mandibular block technic. And the changes in the distribution according to positional change were evaluated in 4 persons. The results are as follows: 1. There are no significant difference between the inferior alveolar nerve block anesthesia and the true mandibular nerve block anesthesia in terms of blood aspiration rate, success rate of anesthesia, onset time of anesthesia, and depth of needle penetration. 2. There are 68.5% of long buccal nerve anesthesia and 54.3% of mylohyoid nerve anesthesia in the true mandibular nerve block anesthesia. 3. There are no significant difference in the success rate of anesthesia between the true mandibular injections with different position of the patients. 4. The radiographic images of the injected solution in the true mandibular nerve block anesthesia showed more deposition near the condylar neck and mandibular notch area than that of the inferior alveolar nerve block anesthesia. 5. There are no significant difference in the radiographic images of the injected solution between the true mandibular nerve block injections with different position of the patients.
