ENT Flashcards
Laryngomalacia clinical signs
- Inspiratory stridor (MCC stridor in infants)
- Symptoms worse when supine, crying, agitated, or feeding
- If severe: FTT, difficulty feeding, OSA, cyanosis
Laryngomalacia treatment
- Symptoms may progress until 6 months but majority of cases resolve by 12-18 months
- If severe: surgical management with supraglottoplasty or tracheostomy
Tracheomalacia etiologies
- Primary: intrinsic defect in cartilaginous tracheal rings
- Secondary (compression of trachea) - mediastinal vasculature, lymphatic malformations, neoplasm
Tracheomalacia clinical signs
Stridor, wheezing, recurrent barking cough, frequent respiratory infections
Nasal polyps signs/symptoms and treatment
- S/sx: persistent mucoid rhinorrhea, chronic nasal congestion, noisy breathing, disturbed sleep
- Exam: glistening fleshy color of polyps
- Treatment: intranasal steroids is first line
Disease associations with nasal polyps
- CF IS THE MOST COMMON AND ALL KIDS NEED A SWEAT TEST!
- Aspirin sensitivity, allergic rhinitis, recurrent sinusitis, and asthma are also associated
Causes of persistent/recurrent purulent otorrhea
- Cholesteatoma, foreign body, histiocytosis, and other inflammatory or malignant conditions
- Persistent purulent otorrhea for > 2 weeks despite treatment is indication to send to ENT
Cholesteatoma
- Squamous epithelium and keratin (white mass behind TM)
- Cause of persistent otorrhea and conductive hearing loss
- FOUL SMELLING discharge despite treatment of perforated TM
- Congenital or acquired
- Tx is surgical removal - can dissolve tissue/bone and reach into the CNS
Cleft palate complications
- Increased risk of eustachian tube dysfunction, middle ear effusions, and conductive hearing loss
- Also often have feeding/language difficulties.
Treatment of sensorineural hearing loss
- Cochlear implants placed by 12 months of age is ideal
Indications for surgical tympanostomy tube removal
- If tube is still in after 3 years
- Migration into middle ear
- Granulation tissue not responding to drops
- Chronic otorrhea that does not respond to treatment
- Resolution of the condition that prompted insertion (eg, repair of cleft palate), especially in an older child
Causes of conductive hearing loss
- Inner and outer ear malformations
- Trauma (perforations)
- Tympanosclerosis (minimal hearing loss, scarring from lots of OM)
- Chronic otitis with effusion (MOST COMMON cause)
- Cholesteatoma
Medication causes of sensorineural hearing loss
- Lasix and ethacrynic acid (temporary)
- aminoglycosides, salicylates
Hearing loss from loud sound exposure
High frequency sensorineural hearing loss
Sudden onset of bilateral sensorineural deafness
Viral labyrinthis - no treatment, some may get hearing back but not all
Infectious causes of sensorineural hearing loss
- In utero: CMV (most common), herpes, rubella, syphilis
- Acquired: bacterial meningitis (usually occurs within first 24 hours of illness – need a hearing test)
Preemie risk factors for sensorineural hearing loss
- Prolonged ventilation
- Hyperbili
- LBW
- Rh factor
- Maternal diabetes
At what age is language development affected by deafness
9 months
- Prior to that cooing and babbling do not depend on hearing
Types of hearing tests based on age
- Behavioral observation audiometry - less than 6 months (only a screening)
- Auditory brainstem response (uses EEG) - good for less than 6 months
- Visual reinforced audiometry (used for ages 6-24 months)
- Play audiometry - ages 2-4
- Conventional pure tone audiometry screen (age > 4)
Flat line or low amplitude tympanogram
Suggests stiff membrane or middle ear fluid (obstructed tympanostomy tube)
High volume tympanogram
Perforated TM
Three criteria for acute otitis media
- Recent abrupt onset
- Bulging TM with effusion
- Erythema of TM
Most common cause of chronic suppurative otitis media
Psuedomonas
Treat with topical/otic ofloxacin
Indications to watch with AOM before giving antibiotics
- Infants over 6 months with unilateral otitis and nonsevere symptoms
- Toddlers overa ge 2 with nonsevere symptoms (unilateral or bilateral
- Can withhold antibiotics for 48-72 hours, 80% will resolve on their own
