title: [Parapharyngeal abscess: perilaryngeal infrahyoid extension].
abstract: Parapharyngeal abscesses are located between the skull base and the hyoid bone. Their infrahyoid extension is usually following the retropharyngeal space, but also can be through the medial aspect of the parapharyngeal space. Thus, surrounding the visceral fascia, they might invade the perilaryngeal and perihypopharyngeal spaces. This results in more significant airway compromise. Computed tomography is essential while locating and evaluating the extension of these infections, specially with regards to the great vessels. We report on 8 parapharyngeal abscesses with perilaryngeal and/or perihypopharyngeal extension. We review their clinical and radiological features, based on computed tomography, as well as their medical and surgical treatment. When medical therapy fails, as they are usually medial to the great vessels, it is possible to perform aspiration and drainage transorally, avoiding the need for cervicotomy, in selected cases.
