1 Common ENT Problems: How to evaluate and when to refer Maria C. Veling M.D. Pediatric Otolaryngology University of Kentucky April

2 Objectives Identify symptoms and findings of clinically significant adenotonsillar hypertrophy Describe the current guidelines for tonsillectomy and adenoidectomy Describe the current treatment guidelines for otitis media Define indications for surgery in pediatric sinusitis Describe other emergent ENT outpatient scenarios

3 Clinical Indicators for T&A Patient with 3 or more infections of tonsils and/or adenoids per year despite adequate medical therapy. Peritonsillar abscess unresponsive to medical management. Chronic or recurrent tonsillitis associated with the streptococcal carrier state and not responding to beta-lactamase-resistant antibiotics. Persistent foul taste or breath due to chronic tonsillitis not responsive to medical therapy. Hypertrophy causing dental malocclusion or adversely affecting orofacial growth documented d by orthodontist. ti t Hypertrophy causing upper airway obstruction, severe dysphagia, sleep disorders, or cardiopulmonary complications. Unilateral tonsil hypertrophy p y presumed neoplastic.

5 Adenotonsillar Hypertrophy Symptoms Snoring Mouth breather Restless Sleep Apnea Difficulty swallowing solids Muffled voice Hypo nasal speech

6 Tonsillar Size 0 in Fossa +1 <25% % % +4 >75%

7 Obstructive indicators for T&A Upper airway obstruction Sleep disordersd Cardiopulmonary complications Dental malocclusion or facial growth abnormalities Severe dysphagia

8 OSA in Children > 400, T&A s are performed per year in children mostly for OSA Most tonsillectomies are performed in children for mild OSA OSA is associated with behavioral problems and is known to significantly affect quality-of-life < 10% of Otolaryngologists request PSG prior to T&A for OSA

9 Pediatric OSA and Behavior Several large studies have shown that children with SDB have behavioral problems Attention Hyperactivity Aggression Irritability Emotional and peer problems Somatic complaints N. Goldstein, et al Arch Otolaryngol Head Neck Surg. 128 (2002) Mitchell RB, Kelly J. Long-Term Changes in the Behavior of Children after Adenotonsillectomy for Obstructive Sleep Apnea. Otolaryngol Head Neck Surg Mar;134(3):374-8.

10 Pediatric OSA- Outcome Studies PSG normalizes in 70-80% of normal children after T&A QOL of life improves dramatically. Over 95% of caregivers report improvement Behavior improves in 50% of children Correlation between improvements in PSG, QOL and behavior is poor Mitchell RB.

14 Goals of adenotonsillectomy Adenotonsillectomy for sleep disordered breathing (SDB) in children is associated with improvements in sleep, quality-of-life life and behavioral problems Approximately 20% of normal weight children and 70% of obese children have persistent SDB after adenotonsillectomy Diminished rate of infection after adenotonsillectomy

15 OTITIS MEDIA 15

16 Otitis Media Otitis media is generally defined by the presence of effusion within the middle ear without reference to its cause or pathogenesis Acute otitis media (AOM) is usually associated with the rapid onset of symptoms and signs of acute infection in the middle ear space, including fever, otalgia, inflammation or bulging of the tympanic membrane, and purulent middle ear effusion Otitis media with effusion (OME) is the presence of Otitis media with effusion (OME) is the presence of serous, mucoid, or mucopurulent fluid in the middle ear without acute symptoms.

17 Natural history Otitis Media After an episode of untreated AOM, spontaneous clearance of OME may be expected in approximately 75% of children within 3 months; with treatment t t of the acute episode, clearance at 3 months may be as high as 90%. Patients with effusions with duration of at least 3 months at the time of diagnosis have the poorest prognosis, with only 27% clearance at 6 months and 32% at 1 year.

18 Oii Otitis Media The pathogenesis is multifactorial infection impaired Eustachian tube function immature immune status allergy

19 Surgical treatment of Otitis Media Acute Otitis Media Most studies of myringotomy with or without antibiotic therapy for AOM suggest no significant advantage over antibiotic therapy alone. The primary value of myringotomy or tympanocentesis is for culture to guide antibiotic therapy. Rosenfeld RM: What to expect from surgical therapy. In Evidence Based Otitis Media. Edited by Rosenfeld RM, Bluestone CD. Hamilton, Ontario: BC Decker; 1999:

20 Surgical treatment of Otitis Media Recurrent Acute Otitis Media (raom) Studies of raom suggest a trend toward improvement with conservative management As a result, for children with raom whose episodes are nonsevere or have occurred only for a limited period, watchful waiting is often indicated. surgery for raom should be recommended only for patients with severe symptoms and a history of at least three or four episodes in a 6-month period, anticipating at best a modest reduction in the frequency of infection

21 Otitis Media with Effusion Management is initiated with two goals in mind Restoration of normal hearing-g Associated with conductive hearing loss causing an average threshold elevation of 25 to 30 db Avoidance of middle ear sequelae- Result from chronic or intermittent negative pressure causing tympanic membrane retraction. ti This process may result in flaccidity and atelectasis in the posterosuperior tympanic membrane and the pars flaccida, culminating in ossicular discontinuity or cholesteatoma. t

22 Surgical treatment of Otitis Media Otitis Media with Effussion (OME) Tympanostomy tubes are a reasonable consideration in patients with at least 3 months of bilateral or 6 months of unilateral effusion, or in patients in whom a majority of the previous year was spent with middle ear disease Patients with effusions for less time but who also have severe symptoms, severe hearing loss, or development of atelectasis or retraction pockets should also be considered Adenoidectomy may be reserved for the second set of tubes, but should be considered primarily in patients with a history of chronic nasal obstruction or adenoiditis

23 Adenoidectomy Many trials now demonstrate that adenoidectomy is efficacious when performed as an adjunctive procedure to tubes. Rosenfeld RM: What to expect from surgical therapy. In Evidence-Based Otitis Media. Edited d by Rosenfeld RM, Bluestone CD. Hamilton, Ontario: BC Decker; 1999: Children with adenoidectomy tend to have fewer episodes of OME and seem to require fewer repeat tube insertions.

25 PEDIATRIC CHRONIC SINUSITIS 25

26 Pediatric Chronic Sinusitis The precise diagnosis of sinusitis in children is often difficult to make because of the overlap of symptomatology with more common conditions such as viral upper respiratory infections and adenoid infection or hypertrophy. Acute rhinosinusitis often presents as a URI with worsening of symptoms (most notably nasal discharge, cough, and halitosis) 7 to 10 days after onset Chronic rhinosinusitis (CRS) is defined as a low- Chronic rhinosinusitis (CRS) is defined as a low grade infectious process lasting more than 3 months

27 Pediatric Chronic Sinusitis Diagnosis Symptoms lasting more then 3 months Nasal obstruction ti Nasal discharge Cough Halitosis Headache Recurrent acute rhinosinusitis (ARS) Six or more episodes of ARS per year, each lasting at least 10 days, with persistent changes on CT at least 4 weeks after medical management and with healthy intervals between episodes

28 Pediatric Chronic Sinusitis Comorbid risk factors- Anything that leads to inflammation and obstruction of the sinus ostia Viral infection Allergic rhinitis Secondary exposure to tobacco smoke Daycare attendance Bacterial load of the adenoidal pad Gastro esophageal reflux disease Cystic Fibrosis Primary Ciliary Dyskinesia Immune deficiency

30 Pediatric Chronic Sinusitis

31 Pediatric i Chronic Sinusitis i i Treatment- Medical Management Amoxicillin/clavulanate, high-dose amoxicillin, cefpodoxime, or cefuroxime Recommended duration of therapy is a total of 10 to 21 days If initial therapy is ineffective, it is switched to a broader spectrum antibiotic, or combination therapy should be considered. Culture-directed therapy Identify and treat any underlying factors that may contribute to sinus disease

32 Pediatric Chronic Sinusitis Treatment- Surgical Management Surgery in children with CS is usually indicated only when there is failure of maximal medical management. First-line surgical management usually consists of adenoidectomy to remove the adenoid pad as a bacterial reservoir for the sinuses. Children whose symptoms persist after adenoidectomy should be referred for immune function and allergy testing and sinus CT Clary R: Is there a future for pediatric sinus surgery?
