Treatment Hilton's method Pterygomandibular space infection Surgical anatomy Aetiology Contaminated needle used for an inferior alveolar nerve block injection. Spread of infection from the lower 3rd molar region. Infection originated from the upper 3rd molar. Follows a posterior superior alveolar nerve block injection. Signs and symptoms Treatment Lateral pharyngeal (parapharyngeal) space infection Surgical anatomy Aetiology The space may become infected from an abscess extending backwards from the lower 3rd molar area or more commonly one passing laterally from a tonsillar abscess. Infection can also spread backwards into it from a sublingual or submandibular space. A rare case infection is the surgical displacement of a lower 3rd molar or the root of the lower 3rd molar distally at the lingual flap and backwards to the lateral pharyngeal space.
