Pediatric HEENT examination

Pediatric HEENT examination

🔴 1. หลักการสำคัญ

  • การตรวจ HEENT ในเด็กต้อง:
    • observe ก่อน touch
    • ใช้ behavioral technique (distraction, caregiver assist)
  • เน้น:
    • developmental variation
    • dysmorphic features
    • early detection ของ systemic disease

🧠 2. HEAD

🔍 Inspection

  • head shape, scalp lesion, trauma
  • mass:
    • bone (exostosis)
    • soft tissue (hemangioma, dermoid, encephalocele)

📏 Head circumference

  • วัดทุก visit ในช่วง 0–2 ปี
  • ใช้ติดตาม:
    • microcephaly
    • macrocephaly

🧩 Fontanelle (high yield)

Finding

Significance

tense/bulging

ICP

sunken

dehydration

early closure

craniosynostosis, microcephaly

delayed closure

hypothyroid, ICP, Down syndrome


🧠 Other clues

  • frontal bossing skeletal/genetic disorder
  • craniotabes rickets, syphilis
  • cranial bruit AV malformation

😊 3. FACE

🔍 Evaluate dysmorphism

  • eyes spacing
  • philtrum
  • auricle position

👉 clue:

  • genetic syndrome / fetal alcohol

🚩 Abnormal findings

  • facial edema allergy / nephrotic / mono
  • unilateral swelling cellulitis / parotitis
  • facial palsy CN VII lesion

👁️ 4. EYES

🔑 Basic exam

  • alignment (corneal light reflex)
  • EOM
  • pupil
  • conjunctiva

🚨 Red flags

🔴 Red reflex abnormal

  • cataract
  • retinoblastoma
    👉 ต้อง refer ทันที

🔴 Leukocoria (white reflex)

  • malignancy until proven otherwise

👁️ Common findings

  • conjunctivitis
  • stye / chalazion
  • ptosis CN III / MG

👀 Strabismus

  • <4 เดือน normal variant
  • 4 เดือน refer ophthalmology

👂 5. EARS

🔍 Inspection

  • low-set ears syndrome
  • preauricular pit/tag risk hearing loss

🩺 Otoscopy (core skill)

normal TM:

  • translucent
  • mobile

abnormal:

Finding

Diagnosis

bulging

AOM

mobility

effusion

perforation

trauma / infection



🧪 Pneumatic otoscopy

  • best for:
    • middle ear effusion

🔊 Hearing assessment

  • newborn screening (ABR/OAE)
  • older whisper / audiometry

👃 6. NOSE

🔍 Exam

  • septum (midline?)
  • mucosa (pink?)

🚩 Important clues

Finding

Suggestion

unilateral foul discharge

foreign body

clear watery discharge

CSF leak

nasal polyp

cystic fibrosis

obstruction newborn

choanal atresia


🔑 Practical

👉 neonate nasal obstruction
ลอง pass NG tube


👄 7. MOUTH & THROAT

🔍 Examine:

  • lips, mucosa, tongue, palate
  • tonsils

🚩 Important findings

🔴 Oral lesions

  • herpetic stomatitis
  • aphthous ulcer
  • immunodeficiency

🔴 Tonsils

  • exudate bacterial infection
  • asymmetry:
    • infection vs lymphoma

👉 red flags lymphoma:

  • rapid growth
  • systemic symptoms
  • large LN

🦷 Teeth

  • eruption delay metabolic/systemic disease

🧠 8. NECK

🔍 Inspection

  • short neck congenital syndrome
  • webbed neck Turner

🧩 Neck mass approach

midline:

  • thyroglossal duct cyst

lateral:

  • lymph node
  • branchial cleft cyst
  • lymphangioma

🚩 Red flags

  • hard, fixed mass
  • systemic symptoms
  • rapidly enlarging

🫀 Other findings

  • JVP cardiac/mediastinal disease
  • torticollis muscular / neuro / reflux (Sandifer)

🧠 9. Clinical pearls (ใช้จริง)

🔑 Must not miss

  • abnormal red reflex refer immediately
  • neonatal nasal obstruction airway emergency
  • unilateral nasal discharge foreign body
  • tonsillar asymmetry + systemic sign rule out malignancy

Pitfalls

  • ไม่ตรวจ red reflex
  • misdiagnose AOM โดยไม่ดู mobility
  • overlook dysmorphic features
  • biopsy midline mass โดยไม่ imaging

🧩 High-yield workflow

1.       Look general + dysmorphism

2.       Airway (nose/oral)

3.       Vision (red reflex)

4.       Hearing (otoscopy + response)

5.       Neck mass differentiation


🔚 Bottom line

Pediatric HEENT exam เป็น เครื่องมือสำคัญในการ detect disease ตั้งแต่ benign life-threatening
ต้อง:

  • รู้ normal developmental variation
  • หา red flags ที่ต้อง refer ทันที
  • ใช้ systematic approach ทุกครั้ง
