| Peritonsillar abscess (PTA), also commonly referred to as quinsy, is defined as a collection of [[pus]] located between the tonsillar capsule and the pharyngeal constrictor muscles.

|
| *In Second and third century BC, Celcius was the first to document in literature the treatment and pathogenesis of tonsillar pathology.
| | ==[[Peritonsillar abscess overview|Overview]]== |
| *In 1700s peritonsillar abscess was first described.
| |
| *In the 1930s and 1940s prior to the advent of antibiotics, surgical management was the most common treatment option for peritonsillar abscess. Interval tonsillectomy was mostly done after symptom resolution.
| |
| *By 1947, Chaud tonsillectomy or immediate surgical tonsillectomy became the treatment option.

| A good understanding of the [[tonsil]] and its surrounding space is important in the pathogenesis of peritonsillar abscess.
| |
| The palatine tonsils are found in an anatomical structure called tonsillar fossa. This fossa is bounded anteriorly by palatoglossal muscle, posteriorly by palatopharyngeal muscle, laterally by a fibrous capsule and tonsillar crypts medially. Contents of the tonsillar crypts are expelled by contraction of the tonsillopharyngeus muscle.<ref name=abd>L. Michaels, H.B. Hellquist Ear, nose and throat histopathology (2nd ed.)Springer-Verlag, London (2001), pp. 281–286</ref> The tonsils form during the last months of pregnancy and becomes fully formed by 6 to 7 years of age. It then undergoes involution until small size remains in older population.
| |
| Located within the soft palate is the supratonsillar space occupied by series of 20 to 25 salivary glands described as Weber's glands. The ducts of these glands form a common duct which opens onto the posterior surface of the [[tonsil]] after passing through the tonsillar capsule. It is proposed that the secretions from these [[glands]] play a rule in food [[digestion]].
| |
| Peritonsillar abscesses form in the area between the palatine tonsil and its capsule.
| |
| | |
| ===Pathogenesis===
| |
| | |
| The pathogenesis of peritonsillar abscess is still not well-understood.<ref name="pmid23612569">{{cite journal| author=Powell EL, Powell J, Samuel JR, Wilson JA| title=A review of the pathogenesis of adult peritonsillar abscess: time for a re-evaluation. | journal=J Antimicrob Chemother | year= 2013 | volume= 68 | issue= 9 | pages= 1941-50 | pmid=23612569 | doi=10.1093/jac/dkt128 | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=23612569 }} </ref> There are two proposed theories believed to be involved in the pathogensis of peritonsillar abscess formation.<ref name=abd>L.

| | |
| *1. It is proposed to arise from an extension of exudative tonsillitis.
| |
| Some authorities believe that blockage of drainage from tonsillar crypt in acute tonsillitis results in spread of infection into the peritonsillar space.
| |
| | |
| *2. Involvement of Weber's gland account for the abscess formation. Some believe that peritonsillar abscess arises from infectious process involving group of salivary glands called Weber's glands located in the supratonsillar space.
| |
| | |
| Antigenic response following any disturbance arising from within the tonsillar crypt mucosa allows for lymphocytic interaction. This disruption in the crypt epithelium may be preceded by infectious process. Invasion and proliferation of the tonsillar crypt by infectious pathogens results in localized edema and influx of neutrophils. This is clinically seen as inflammed tonsil with or without exudation.<ref name=abd>L. Michaels, H.B. Hellquist Ear, nose and throat histopathology (2nd ed.)Springer-Verlag, London (2001), pp. 281–286</ref> Pus accumulation within tissue behind the supratonsillar space leads to tonsillar bulging, uvula and palate deviation.

| ===Gross pathology===
| |
| On gross pathology, the tonsillar region is edematous and inflammed as shown below:

| |
| | |
| ==Causes==
| |
| PTA usually arises as a complication of an untreated or partially treated episode of acute [[tonsillitis]]. The infection, in these cases, spreads to the [[Peritonsillar abscess|peritonsillar]] area (peritonsillitis). This region comprises loose connective tissue and is hence susceptible to formation of abscess. Peritonsilar abscess can also occur ''de novo''.
| |
| Both aerobic and anaerobic bacteria can be causative.<ref name="pmid18039418">{{cite journal| author=Megalamani SB, Suria G, Manickam U, Balasubramanian D, Jothimahalingam S| title=Changing trends in bacteriology of peritonsillar abscess. | journal=J Laryngol Otol | year= 2008 | volume= 122 | issue= 9 | pages= 928-30 | pmid=18039418 | doi=10.1017/S0022215107001144 | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=18039418 }} </ref><ref name="pmid18039418">{{cite journal| author=Megalamani SB, Suria G, Manickam U, Balasubramanian D, Jothimahalingam S| title=Changing trends in bacteriology of peritonsillar abscess. | journal=J Laryngol Otol | year= 2008 | volume= 122 | issue= 9 | pages= 928-30 | pmid=18039418 | doi=10.1017/S0022215107001144 | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=18039418 }} </ref>

| | |
| * Symptoms start appearing 2-8 days before the formation of [[abscess]].

| ===Imaging Findings===
| |
| The diagnosis of peritonsillar abscess may be made without the use of imaging however, imaging options may help in differentiating peritonsillar abscess from other simialr conditions example, peritonsillar cellulitis, retropharyngeal abscess and epiglottitis.
| |
| | |
| ====Ultrasound====
| |
| This is helpful in differentiating peritonsillar abscess from peritonsillar cellulitis as well as a guide during abscess drainage.

| *Peritonsillar abscess appears as focal irregularly marginated hypoechoic area.
| |
| *Irregular hypoechoic areas within the tonsil may represent pockets of developing purulence or necrosis called intratonsillar abscesses.
| |
| *Peritonsillar cellulitis appears as enlarged tonsil (arrows) with ill-defined margins and markedly increased echogenicity of surrounding soft tissues that suggests significant inflammatory change/cellulitis.
