During the preoperative assessment of patients with suspected congenital airway anomalies, several abnormalities may be identified through inspection. Common airway congenital anomalies that might be noted include:
-
Cleft Lip and Palate: Observe for any visible clefts in the lip or palate, which may affect airway management.
-
Micrognathia (Small Jaw): This can lead to a compromised airway and is often seen in conditions like Pierre Robin sequence.
-
Macroglossia ( Enlarged Tongue): Enlarged tongues can obstruct the airway, common in conditions such as Down syndrome.
-
Nasal Abnormalities: Look for nasal deformities (e.g., choanal atresia) which can affect breathing patterns.
-
Tracheomalacia: While not directly visible, indicators may include stridor or wheezing during inspection.
-
Short Neck: This may be observed in some syndromes (like Turner syndrome) that could suggest difficulties with intubation.
-
Thoracic Abnormalities: Conditions like pectus excavatum or pectus carinatum can impact respiratory function.
-
Presence of Other Syndromic Features: Syndromes like Treacher Collins syndrome or other craniofacial syndromes can have associated structural abnormalities that might be evident on examination.
-
Thoracic or Cervical Spinal Anomalies: These may not be visually prominent but are relevant to assess for potential complications during intubation.
-
Stridor or Respiratory Distress: Any observable signs of respiratory distress or stridor should heighten suspicion of underlying airway anomalies.
The examination findings need to be correlated with the patient’s history and may necessitate further diagnostic investigation (e.g., imaging or endoscopy) to confirm the diagnosis and plan for appropriate management.
