25
Large erythematous mass in ears after tympanostomy tube placement
- Tympanostomy tube granuloma (common complication) | - Can lead to bloody drainage
26
Cause/symptoms of otitis externa
- Pain with movement of pinna - Cause is pseudomonas - Tx antibiotics/steroids (fluoroquinolone) - Ppx: acidify ear following swimming and dry with hair dryer
27
Swelling/deformity of external ear following blunt trauma management
Cauliflower ear | - Ice packs and pressure then evacuation of hematoma by needle aspiration to prevent potential cartilage loss
28
Causes of mastoiditis
- MC complication of acute otitis media - Strep pneumo, H. flu, S pyoenes, S aureus - Dx with CT and tympanocentesis with culture - Sx: swelling/erythema, tenderness over mastoid, outwardly displaced pinna
29
Associations with nasal polyps
- CF - Asthma - Chronic allergic rhinitis - Chronic sinusitis
30
Cyanosis with feeding and resolution with crying
- Choanal atresia - 50% are associated with genetic anomalies - Evaluation by inability to pass catheter through nares
31
Timing of when sinuses develop
- Maxillary and ethmoid: at birth | - Sphenoid and frontal: 5-6 years of age
32
Persistent nighttime cough and/or bad breath with persistent nasal congestion for 7-10 days, can also have toothache or sore throat
- Acute sinusitis - MC organisms: pneumococcus, H flu, moraxella Tx: amox (unless they failed that or if they attend daycare then augmentin)
33
Complications of acute sinusitis
- Ehtmoid --> orbital cellulitis | - Frontal --> brain abscess
34
Treatment of chronic sinusitis
Antibiotics (surgery if necessary) - can take 2-3 months | - CT scan is diagnostic

39
Retropharyngeal abscess vs peritonsillar abscess vs epiglottitis
- Retro: younger (less than age 4), hyperextended neck - Peritonsillar: school age/adolescents - Epiglottitis: toxic appearing, prefer to lean forward, air hungry

51
Progressive hoarseness that is less severe in the morning without stridor or dysphagia

Asthma like symptoms but normal pulse ox and clear lung fields with no response to bronchodilators, hoarseness following extubation
Vocal cord dysfunction - have inspiratory stridor (not wheezing)
53
Vascular ring symptoms
Present with expiratory stridor and feeding difficulties
54
Cause of biphasic stridor
Subglottic stenosis (congenital or acquired)
55
4-5 year old with inspiratory stridor, leaning forward, drooling, no cough
Epiglottitis - Thumb sign on lateral neck film - Hib is most common cause (less now b/c vaccine) - Tx: OR for evaluation, blood culture, rocephin
56
Most common causes of croup
- Parainfluenza, influenza, RSV | - Measels (watch out for unimmunized)

Barky nonproductive cough
Spasmodic croup
58
Rapid deterioration of a patient with viral croup
Bacterial tracheitis - Pseudomembranous croup - Usually caused by S aureus but can also be moraxella or H flu - Neck film with subglottic narrowing - Tx: intubate, clear secretions, broad spectrum antibiotics
59
Thyroglossal duct cyst
Midline lesion on the anterior neck that moves upward with swallowing - Can have functioning thyroid tissue in it
60
Causes of parotitis
- Viral: preschool/school age with vague symptoms, swelling/erythema around opening of Stensen's duct, consider HIV/mumps - Bacterial: before age 10, toxic, Staph aurerus - Salivary gland stand - recurrent swelling of both parotid glands
