Cephalhaematoma and subgaleal haemorrhage — branching viva

Branching viva on the anatomical-plane classification of birth scalp swellings, the suture-line discriminator, recognition and resuscitation of a subgaleal haemorrhage, and the complications and prevention bundle around operative vaginal delivery.

Prompt
A term newborn delivered by vacuum extraction has a diffuse boggy scalp swelling crossing the suture lines, with pallor and a heart rate of 180. The examiner asks: 'Walk me through your diagnosis and immediate management.'
Opening answer to give if asked to summarise

Three birth-related scalp swellings are told apart by their anatomical plane, and the plane decides the danger. Caput succedaneum is subcutaneous and harmless; cephalohaematoma is subperiosteal, confined to one bone, does not cross the suture line, and is usually benign; subgaleal haemorrhage is subaponeurotic, crosses all sutures and the fontanelle, and is the dangerous one because that large space can conceal enough blood to kill a newborn through hypovolaemic shock. [3] In this infant, the diffuse boggy swelling crossing the sutures with pallor and tachycardia is a subgaleal haemorrhage with evolving shock — I would secure access and begin volume resuscitation immediately. [1] [4]

Branch 1 — The bedside assessment and the plane

Examiner: "You are called to the postnatal ward. Talk me through your assessment of this swelling." [3]

  • Map the swelling to the suture line first. A swelling that crosses the sagittal and lambdoid sutures and the anterior fontanelle is subaponeurotic (subgaleal) or subcutaneous (caput); a swelling that stops at the suture of one bone is subperiosteal (cephalohaematoma). [3] [8]
  • Feel the consistency. Diffuse, boggy and fluctuant, with ecchymosis tracking into the eyelids, forehead and neck, is subgaleal; firm, well-circumscribed and non-pitting is cephalohaematoma; soft, pitting and oedematous is caput. [8]
  • Assess the perfusion. Pallor, tachycardia, prolonged capillary refill and hypotension are the signs of the hypovolaemic shock that makes a subgaleal bleed dangerous. [3]
If the examiner asks why the suture line matters

Because the periosteum is anchored to the suture margins of each bone. A subperiosteal cephalohaematoma is therefore trapped within one bone and self-limits; a subaponeurotic bleed lies beneath the galea in a large boundary-less space and spreads across the whole vault. The plane — set by which layer was sheared — is the single determinant of whether the bleed is benign or lethal. [3] [8]
