essay 11 - regional block Anaesthesia of the maxilla (intra and extra oral). Anatomic and topographic features. Techniques

What is Maxillary Nerve Block

• anaesthesia is the maxillary branch of the trigeminal nerve.

• This branch supplies; maxillary teeth, buccal/labial maxillary mucosa, Skin of mid face and the palatal mucosa

List The maxillary nerve block techniques

1. intraoral techniques

2. extra oral techniques

3. other vestibular maxillary nerve blocks

4. other palatal maxillerina blocks

contraindications of intraoral technique

• has a high risk of carrying infection into the pterygopalatine fossa

• contraindicated in cases of; paediatric patients, uncooperative patients, traumatised or infected tissues at the injection site, trismus, hemophiliacs (person with hemophilia)

describe the intraoral technique from the tuberosity approach

describe the intraoral technique from the Greater Palatine Foramen approach

list the branches of the maxillary nerve

• the maxillary nerve passes through the Foramen rotundum and then enters the Pterygopalatine fossa and gives of several branches:

• zygomatic nerve → zygomaticofacial and zygomaticotemporal

• infraorbital nerve → continues as Terminal branch

• superior alveolar nerves (posterior, Middle, anterior)

• Palatine nerves (greater and lesser)

• Nasopalatine

• pharyngeal branch

• posterior superior nasal branches

• meningeal branch

• Zack Is Superman Part-time Not Paid Pretty Much

What areas are supplied by Zygomatic nerve and its divisions - zygomaticofacial and zygomaticotemporal

• skin over the zygomatic (cheek) and temporal regions

what areas are supplied by infraorbital nerve

• Lower eyelid

• side of nose

• Upper lip

what areas are supplied by Superior Alveolar nerves (posterior, middle, anterior)

• posterior → molars

• middle → premolars

• anterior → canines and incisors

what areas are supplied by Palatine nerves (greater and lesser)

• hard and soft palate

• palatal mucosa

• gingiva

what areas are supplied by Nasopalatine nerve

• anterior hard palate

• palatal gingiva behind incisors

what areas are supplied by Pharyngeal Branch

• mucosa of nasopharynx

what areas are supplied by posterior superior nasal branches

• lateral wall of nasal cavity

• nasal septum

what areas are supplied by Meningeal branch

• dura mater of Middle Cranial Fossa

Describe the extraoral Method from the lateral approach

describe the extraoral method from the anterior approach

Describe the extraoral Method from the orbital route

describe the extra oral method from the intranasal route

List The other vestibular maxillary nerve blocks

• posterior superior alveolar nerve block

• middle superior alveolar nerve block

• anterior superior alveolar nerve block

describe posterior superior alveolar nerve block

describe Middle superior alveolar nerve block

Describe anterior superior alveolar nerve block

List The Other Palatal Maxillary Nerve Blocks

• greater Palatine nerve block

• nasopalatine nerve block

• anterior middle superior alveolar nerve block - AMSA injection

describe the Greater Palatine nerve block

describe the nasopalatine nerve block

Describe the anterior middle superior alveolar nerve block - AMSA injection
