  1. Adenotonsillar disease ShahinBastaninejad, MD, ORL-HNS Surgeon Assistant professor of tehran university of medical sciences

  2. Anatomy Tonsil boundary • Plicatriangularis Adenoid boundary • Posterior aspect of the nasal septum • Fossa of Rosenmüller • Passavant’s ridge

  3. Waldeyer’s Ring

  4. Presentation outlines • Acute Infections • Chronic diseases • Obstructive hyperplasia • Mass • Surgery

  5. Acute Infections

  6. Acute Adenotonsillitis Etiology • 85% of this problem is due to the viral infection (less in children) • In bacterial infections there is about 40% antibiotic resistancy (due to beta-lactamase-producing germs) • GABHS is the most important pathogen because of potential sequelae

  7. Bacteriology of adenotonsillitis • Group A beta-hemolytic is most recognized pathogen • This organism is associated with a risk of rheumatic fever and glomerulonephritis • Many other organisms are involved : • H.influenza • S. aureus • Streptococcus pneumoniae

  8. GABHS • More common in 5 to 15 years old children • Not seen in less than 3 years

  9. Diagnosis • Viral pharyngitis symptoms: • Coryza • Hoarseness • Cough • Conjunctivitis • Centor criteria for GABHS: • Hx of fever more than 38 • Anterior cervical LAP • Pharyngeal or Tonsillar exudate • Absence of cough

  10. Approach to the Centor scoring • 0-1  Abx not needed • 2-4  perform Cx • Clue : when all 4 scores are present in 44% of the patients there is no GABHS

  11. Treatment Plan • Delay in treatment up to 9 days can be acceptebale • When empiric txy? • Lack of Pt .f/u • Lack of Lab. access • Toxic presentation • In some extends when all 4 measures present

  12. In parentheses!!! • When culture is positive there are two possibilites: • True infection • Carrier state • In this scenario, serological evaluation with ASO(anti-streptolysin O) will be usefull (in true infection it will be more than 3 times than its usual range)

  13. Medical Management • Penicillin is first line treatment  oral medication is preferable (penicillin V) • Other choices: • Amoxicillin (wide spectrum than Pencillin V) • Macrolides • Clindamycin

  14. Recurrent or unresponsive infections require treatment with beta-lactamase resistant antibiotics such as • Clindamycin • Augmentin • Penicillin plus rifampin (or Erythro + Metro)

  15. If no response after 48 hr, re-evaluate patient for the followings: • Sequelea • Patient’s incompliance • Other underlying disease • Abx failure

  16. Peritonsillar abscess • Abscess formation outside tonsillar capsule • Signs and symptoms: • Fever • Sore throat • Dysphagia/odynophagia • Drooling • Trismus • Unilateral swelling of soft palate/pharynx with uvula deviation

  17. Be aware of ICA Aneurysm!

  18. Peritonsillarabscess… • Thought to be extension of tonsillitis to involve surrounding tissue with abscess formation • Recently described to be an infection of small salivary glands in the supratonsillar fossa called Weber’s glands • Would explain superior pole involvement and the usual absence of tonsillar erythema/exudates

  19. Candidiasis

  20. Infectious Mononucleosis

  21. IMN • Clinical diagnosis can be made from the characteristic triad of fever, pharyngitis, and lymphadenopathy lasting for 1 to 4 weeks • Laboratory tests are needed for confirmation • Serologic test results include a normal to moderately elevated white blood cell count, an increased total number of lymphocytes (more than 50%), greater than 10% atypical lymphocytes, and a positive reaction to a "mono spot" test

  22. IMN • When "mono spot" or heterophile test results are negative, additional laboratory testing may be needed to differentiate EBV infections from a mononucleosis-like illness • EBV-Specific Laboratory Tests: • IgM and IgG to the viral capsid antigen • IgM to the early antigen • antibody to EBNA

  23. IMN – Test interpretation • Primary Infection: Primary EBV infection is indicated if IgM antibody to the viral capsid antigen is present and antibody to EBNA is absent • Past Infection: If antibodies to both the viral capsid antigen and EBNA are present, then past infection (from 4 to 6 months to years earlier) is indicated

  24. IMN – Test interpretation • Reactivation: In the presence of antibodies to EBNA, an elevation of antibodies to early antigen suggests reactivation • Chronic EBV Infection: Reliable laboratory evidence for continued active EBV infection is very seldom found in patients who have been ill for more than 4 months

  25. Diphtheria

  26. Chronic disease

  27. Chronic Tonsillitis • Chronic sore throat • Malodorous breath • Presence of tonsilliths • Persistent tender cervical lymphadenopathy • Lasting at least 3 months • Be aware of Anaerobic infections

  28. Cryptic tonsils • Hyperkeratosis, mycosis leptothrica • Tonsilloliths

  29. Obstructive Hyperplasia

  30. Obstructive Adenoid Hyperplasia • Signs and Symptoms • Obligate mouth breathing • Hyponasal voice • Snoring and other signs of sleep disturbance

  31. Obstructive Tonsillar Hyperplasia • Snoring and other symptoms of sleep disturbance • Muffled voice • Dysphagia

  32. Tonsillar Mass

  33. Malignant Neoplasms • Most common is lymphoma • Non-Hodgkin’s lymphoma • Rapid unilateral tonsillar enlargement associated with cervical lymphadenopathy and systemic symptoms

  34. Lymphoma

  35. SCC

  36. Congenital tonsillar masses • Teratoma • Hemangioma • Lymphangioma • Cystic hygroma

  37. Surgery

  38. Tonsillectomy(2010-AAOHNS) • Infection indications: • Pharyngitis more than 7 / yr in 1 yr • More than 5 / yr for 2yrs • More than 3 / yr for 3yrs • Recurrent infections with modifying factors: • Multiple Abx allergy / intolerance • PF.ASP.A: periodic fever/aphthous stomatitis and pharyngitis/adenitis • History of peritonsillar abscess

  39. TnosillectomyCont… • Persistent foul taste or breath due to chronic tonsillitis not responsive to medical therapy • Chronic or recurrent tonsillitis associated with streptococcal carrier state and not responding to beta-lactamase resistant antibiotics • Unilateral tonsil hypertrophy presumed to be neoplastic

  40. Adenotonsillectomy • ATH and Sleep disordered breathing (SDB) • Severity of the SDB depends on adenotonsillar size and/or Craniofacial anatomy and/or neuromuscular tone • Ask for comorbid conditions: Growth retardation / poor school performance / enuresis / behavioral problems (ADHD,…) • Polysomnography indications (PaO2 less than 85% and/or AHI>5)  check PSG in obese patient/down syndrome/craniofacial anomaly &…

  41. Adenoidectomy • Infection: • Purulent adenoiditis • Adenoid hypertrophy associated with: • Chronic otitis media with effusion • Chronic recurrent acute otitis media • Chronic otitis media with perforation • Otorrhea or chronic tube otorrhea • Obstruction (next slide) • Other: • Suspected neoplasia • Adenoid hypertrophy associated with chronic sinusitis

  42. Adenoidectomy Cont… • Obstruction: • Adenoid hypertrophy associated with excessive snoring and chronic mouth-breathing • Sleep apnea or sleep disturbances • Adenoid hypertrophy associated with: • Corpulmonale • Failure to thrive • Dysphagia • Speech abnormalities • Craniofacial growth abnormalities • Occlusion abnormalities • Speech abnormalities

  43. Pre-Op Evaluation ofAdenoid Disease • Triad of hyponasality, snoring, and mouth breathing • Rhinorrhea, nocturnal cough, post nasal drip • “Adenoid facies” • long face, crowded incisors

  44. Pre-Op Evaluation of AdenoidDisease Evaluate palate • Symptoms/FH of CP or VPI • Bifid uvula • CNS or neuromuscular disease • Preexisting speech disorder?

  45. Pre-Op Evaluation of Adenoid Disease Lateral neck films are useful only when history and physical exam are not in agreement. Accuracy of lateral neck films is dependent on proper positioning and patientcooperation.
