25
Features of OME.
- reduction in hearing - ear pain - discharge
26
OME examination findings.
Otoscopy: - dull tympanic membrane - retracted tympanic membrane - air bubbles - visible fluid level
27
Management of OME.
Audiometry referral to diagnose the extent of hearing loss. Treat conservatively and self-resolves within 3 months. Grommet's if persistent.
28
Which comorbidities are associated with OME?
- Down's syndrome - cleft palate
29
What are the broad causes of hearing loss?
- congenital - perinatal - postnatal
30
Congenital causes of hearing loss.
- maternal rubella infection - maternal CMV infection - genetic deafness - Down's syndrome
31
Perinatal causes of hearing loss.
- prematurity - hypoxia during birth
32
Postnatal causes of hearing loss.
- jaundice - meningitis - encephalitis - otitis media / OME - chemotherapy
33
What screening is used to identify congenital hearing problems early?
Newborn hearing screening programme tests hearing in all neonates. Involves specialist equipment that delivers sound to each eardrum individually, and checks for a response.
34
Presentation of hearing loss.
- ignoring calls or sounds - frustration or bad behaviour - poor speech and language development - poor school performance
35
Management of hearing loss.
Diagnosis confirmed by audiometry. MDT involvement: - SALT - educational psychologist - ENT specialist - hearing aids - sign language
36
Where do most nosebleeds originate?
Kiesselbach's plexus - AKA Little's area. Little's area is is most commonly affected by the Little fingers.
37
Presentation of nosebleeds.
Unilaterally bleeding. May present with vomiting blood if children swallow blood during a nosebleed.
38
Nosebleed triggers.
- nose picking - colds - vigorous nose blowing - trauma - changes in weather
39
First aid management of nosebleeds.
- sit up and tilt the head forwards - squeeze the soft part of the nostrils together for 10-15 minutes - spit any blood rather than swallowing
40
Safety netting advice for nosebleeds.
Go to hospital if: - bleeding doesn't stop after 10 minutes - severe bleeding - bilateral bleeding - unstable
41
Hospital treatment of nosebleeds.
1. Nasal packing using nasal tampons. 2. Nasal cautery using a silver nitrate stick.
42
After treating a nosebleed, what is the role of naseptin?
Reduces crusting, inflammation and infection.
43
Contraindications of naseptin.
- peanut allergy - soya allergy
44
What is cleft lip?
Congenital condition causes a split or open section in the upper lip. Cleft palate if the defect exists in the hard or soft palate at the roof of the mouth.
45
Causes of cleft lip.
Occur randomly most of the time. Associations with family history (loosely).
46
Complications of cleft palate.
Issues with: - feeding - swallowing - speech - psycho-social implications
47
Management of cleft lip.
Refer to cleft lip services. First priority is to ensure baby can eat and drink, involving specially shaped bottles and teats. Definitive treatment is to surgically correct the cleft lip or palate.
48
What is tongue tie?
Baby is born with a short and tight lingual frenulum, preventing them extending their tongue out of the mouth. Presents as poor feeding.
49
Management of tongue tie.
Frenotomy - cutting the tongue tie. Can be done on the ward or in the clinic without any anaesthetic.
50
What is a cystic hygroma?
Malformation of the lymphatic system resulting in a cyst filled with lymphatic fluid.
51
Features of cystic hygroma.
Most commonly present on the neck or armpit: - large - soft - non-tender - transilluminate
52
Complications of cystic hygroma.
Interfere with feeding, swallowing or breathing. Infection - hot and tender. Haemorrhage into the cyst.
53
Management of cystic hygroma.
Aspiration, surgical removal and sclerotherapy are treatment options. If mild, may be able to watch and wait for regression.
54
Pathophysiology of thyroglossal cyst.
In fetal development, the thyroid gland migrates from the base of the tongue down to the neck in its final position infront of the trachea. It leaves a track behind called the thryoglossal duct, which usually obliterates. If obliteration doesn't occur, it can give rise to a fluid filled cyst.
55
Differentials for thyroglossal cyst.
- ectopic thyroid tissue
56
Diagnostic workup of thyroglossal cyst.
- ultrasound - CT scan
57
Management of thyroglossal cyst.
Surgical removal to provide confirmation of the diagnosis on histology and prevent infections. The cyst can reoccur after surgery unless the full thyroglossal duct is removed.
58
Pathophysiology of branchial cyst.
Congenital abnormality when the second branchial cleft fails to form properly, leaving a space surrounded by epithelial tissue in the lateral neck. The space can fill with fluid, resulting in a branchial cyst.
59
Features of branchial cyst.
- round - soft - cystic - anterior triangle of neck
60
What is a branchial cleft sinus?
When the branchial cyst is connected via a tract to the outer skin surface - there is a small hole visible in the skin beside the cyst.
61
What is a branchial fistula?
A connecting tract between the oropharynx to the outer skin surface via a branchial cyst.
62
Management of branchial cyst.
Surgical excision appropriate if recurrent infection or diagnostic uncertainty. Histological confirmation.
