Retro pharyngeal abscess is infection followed by collection of pus in retro pharyngeal space. In the adult group they are usually secondary to trauma, foreign bodies, or as a complication of dental infections. Early diagnosis and the wide spread use of antibiotics have made these infections less common today . Non-specific acute retro pharyngeal abscess most commonly occurs in infants and young children. It is rare in adults mostly associated with tuberculosis of the cervical spine.
