new qs-Injection techniques- complications

[Guest guest]

Hi guysHere is the new qsWhich of the following techniques could lead to the following complications: hematoma, trismus, temporary paralysis of cranial nerves III, IV, VI, diplopia, and paralysis of the eye?1. Posterior superior Alveolar (PSA)2. Maxillary Nerve Block (V2)3. Gow-Gates mandibular nerve block4. Akinosi technique5. Inferior alveolar nerve block Kind regardsLee

Hello everyoneanswer: 3Gow-Gates mandibular nerve block (GGMNB) technique/ third division nerve block/ V3 nerve block.2%incidence of aspiration, success rate more than 95%Nerve anesthetized:1. Inferior alveolar2. Mental3. Incisive4. Lingual5. Mylohyoid6.Auriculotemporal7.Buccal N (in 75% of the patients)Indications:1.Multiple procedures on mandibular teeth2.When buccal soft tissue anesthesia, from the third molar to the midline, is required3.When lingual soft tissue anesthesia is required4. When a conventional inferior alveolar nerve block is unsuccessfulContraindications:1.Infection or acute inflammation in the area of

injection2.Patients who

might bite either their lip or their tongue, such as young children and physically or mentally handicapped adults.3.Patients who are unable to open their mouth wide.Advantages:1.Requires only one injection; a buccal nerve block not usually necessary2.High success rate (>95%)3.Minimum aspiration rate4. Few postinjection complications (i.e. trismus)5. Provides successful anesthesia where a bifid inferior alveolar nerve and bifid mandibular canals are present.Disadvantages:1.Lingual and lower lip anesthesia is uncomfortable for many patients and possibly dangerous for certain individuals2.The time to onset of anesthesia is somewhat longer (5 min) than with an inferior alveolar nerve block (3-5 min)Technique:1. Pt in a supine position with mouth wide open to allow translation of the condyles2.Intraoral landmarks: injection distal to Max. 2nd molar at height of ML

cusp3.Target area: lateral side of the condylar neck, just below the insertion of the lateral pterygoid muscle4. Advance until neck of the condyle contacted5. Aspirate: Maxillary artery inferior to target area6.Usually just 1.8cc7.Pt. keep mouth open 1-2 min. after injectionComplications:hematoma,

trismus rare, temporary paralysis of cranial nerves III, IV, VI. Diplopia, paralysis of the eye. If bone is not contacted, do not administer anesthesia.
