Which of the following is NOT a landmark for the Akinosi block?

The Akinosi block, also known as the closed-mouth maxillary nerve block, is a type of anesthesia technique used primarily to anesthetize the maxillary molars and surrounding tissues. To perform the Akinosi block, certain anatomical landmarks are utilized to precisely locate the target area for injection.

The pterygomandibular raphe is not a landmark for the Akinosi block. This raphe serves as a reference point primarily for the inferior alveolar nerve block instead. In the Akinosi technique, anesthesia is more reliant on landmarks that denote the maxillary area and the region surrounding the maxilla.

The correct landmarks for the Akinosi block include the maxillary tuberosity, the coronoid notch, and the mucogingival junction of the maxillary third molar. The maxillary tuberosity helps identify the posterior aspect of the arch for placement, the coronoid notch assists in setting the depth of the injection, and the mucogingival junction provides a point of reference to determine the anterior barrier of the injection site.

Understanding these anatomical structures helps ensure the proper administration of the Akinosi block to achieve effective anesthesia. The focus on the specific landmarks associated with the technique emphasizes the intric
