The parapharyngeal space (also termed the lateral pharyngeal space), is a potential space in the head and the neck. It has clinical importance in otolaryngology due to parapharyngeal space tumours and parapharyngeal abscess developing in this area. It is also a key anatomic landmark for localizing disease processes in the surrounding spaces of ...
A parapharyngeal abscess is a deep neck space abscess of the parapharyngeal space (or pharyngomaxillary space), which is lateral to the superior pharyngeal constrictor muscle and medial to the masseter muscle. [1] This space is divided by the styloid process into anterior and posterior compartments.
Extensive spread in parapharyngeal space Carotid artery, Carotid sheath Metastasis to regional lymphnodes is common as the tonsil has a rich supply of lymphatics giving way to the tumor cells to metastasis to other lymph nodes (commonly the lymph nodes of neck) and cause lymphydenopathy.
A common symptom of laryngeal papillomatosis is a change in voice quality. More specifically, hoarseness is observed. [4] [5] As a consequence of the narrowing of the laryngeal or tracheal parts of the airway, shortness of breath, chronic cough and stridor (i.e. noisy breathing which can sound like a whistle or a snore), can be present.
A computed tomography (CT) scan is the definitive diagnostic imaging test. [4] X-ray of the neck often (80% of the time) shows swelling of the retropharyngeal space in affected individuals. If the retropharyngeal space is more than half of the size of the C2 vertebra, it may indicate retropharyngeal abscess. [5]
Behind the ostium of the eustachian tube (ostium pharyngeum tuba auditiva) is a deep recess, the pharyngeal recess (fossa of Rosenmüller). Clinical significance
Laboratory investigations reveal signs of a bacterial infection with elevated C-reactive protein, erythrocyte sedimentation rate and white blood cells (notably neutrophils). Platelet count can be low or high. Liver and kidney function tests are often abnormal. [citation needed] Thrombosis of the internal jugular vein can be displayed with ...
