AB  - When  infection  penetrates  the  tonsillar  capsule  and  involves  the  surrounding  tissues,  peritonsillar  cellulitis  results.  Following  therapy,  peritonsillar  cellulitis  usually  either  resolves  over  several  days  or  evolves  into  peritonsillar  abscess  (eFigure  8–7).  Peritonsillar  abscess  (quinsy)  and  cellulitis  present  with  severe  sore  throat,  odynophagia,  trismus,  medial  deviation  of  the  soft  palate  and  peritonsillar  fold,  and  an  abnormal  muffled  (“hot  potato”)  voice.  CT  may  be  a  useful  adjunct  to  clinical  suspicion,  but  imaging  is  not  required  for  the  diagnosis.  The  existence  of  an  abscess  may  be  confirmed  by  aspirating  pus  from  the  peritonsillar  fold  just  superior  and  medial  to  the  upper  pole  of  the  tonsil  (eFigure  8–8).  A  19-gauge  or  21-gauge  needle  should  be  passed  medial  to  the  molar  and  no  deeper  than  1  cm,  because  the  internal  carotid  artery  may  lie  more  medially  than  its  usual  location  and  pass  posterior  and  deep  to  the  tonsillar  fossa.  Most  commonly,  patients  with  peritonsillar  abscess  present  to  the  emergency  department  and  receive  a  dose  of  parenteral  amoxicillin  (1  g),  amoxicillin-sulbactam  (3  g),  or  clindamycin  (600–900  mg).  Less  severe  cases  and  patients  who  are  able  to  tolerate  oral  intake  may  be  treated  for  7–10  days  with  oral  antibiotics,  including  amoxicillin,  500  mg  three  times  a  day;  amoxicillin-clavulanate,  875  mg  twice  a  day;  or  clindamycin,  300  mg  four  times  daily.
