Septal Haematoma

Red Flags

  • Septal abscess formation with features including increasing pain, fever and purulent nasal discharge.
  • If there is a history of trauma, ensure other injuries are excluded.

 

Why is this important?

The blood supply runs within the mucoperichondrium surrounding the septal cartilage.  Shearing forces from trauma tear these vessels and a septal haematoma forms in the potential space between the two layers (Figure 1). This can result in avascular necrosis and possible formation of a septal abscess through secondary infection.

Avascular necrosis or secondary infection can lead to a permanent septal perforation and/or saddle nose deformity. In children, destruction of the septum can cause altered growth of the midface and permanent facial deformity. Rarely, a septal abscess can spread intracranially via the venous drainage of the mid face, leading to cavernous sinus thrombosis

When to involve the ENT registrar

  • Discuss any patient with a suspected haematoma: confirm this by aspiration
  • Discuss all cases of septal abscess or suspected intracranial extension

 

Who to admit

All patients with a septal haematoma should be admitted as they will require drainage of the haematoma +/- nasal packing to prevent re-accumulation of the haematoma +/- intravenous antibiotics, depending on the situation.

 

Assessment and recognition

  • Septal haematoma should be suspected in any patient presenting with a history of facial or nasal trauma
  • A full nasal examination should be performed, along with a holistic assessment of other injuries using the ATLS approach
  • Septal haematomas most commonly occur in the anterior portion of the septum and appear as a red, usually bilateral mucosal swelling, see youtube link below. (NB - A septal haematoma is not simply the presence of blood clots in the nasal passages)
  • If in doubt as to the nature of the swelling, the mass can be palpated with a gloved finger or a blunt instrument such as a microbiology swab; a haematoma feels soft and fluctuant whereas a deviated nasal septum will be firm and will be concave on the opposite side 
  • A definitive diagnosis can be achieved by needle aspiration: a bloody or serosanguinous aspirate is a positive finding; this is generally done by spraying the nose with local anaesthetic spray and aspirating with a 10ml syringe and green needle

 

Immediate and overnight management

A septal haematoma should ideally be drained within hours of presentation as necrosis can occur within 24 hours. Initial aspiration with a wide bore needle may confirm the diagnosis and may potentially be fully therapeutic.

Discuss management with a senior, as most patients require formal incision and drainage under general anaesthesia.

In cases of suspected infection, send the aspirate can for M,C+S.  All septal abscesses require incision and drainage under general anaesthesia.

Following drainage, through-and-through dissolvable sutures may be placed into the septum. Many surgeons also pack the nose bilaterally to prevent re-accumulation of the haematoma. Patients may be started on antibiotics to minimise the risk of secondary infection. 

For reference, here is a video on incision and drainage (starts at 03:10). 

 

Further management

Patients who have had a formal I&D under general anaesthesia would normally have bilateral nasal packs +/- a corrugated drain placed in between the mucoperichondrial layer and the nasal septum. These typically stay in for 36-48 hours and the patients can be placed on antibiotics.

Patients who have had repeated haematomas or a septal abscess are high risk for septal perforation and saddle deformity.

It is best that all patients who have had a septal haematoma drained formally be followed up in the main outpatients clinic in 2-3 weeks.
