Maxillofacial Haemorrhage
• ATLS Principles
• Acute concerns:– Airway care– Control of profuse bleeding– Vision threatening injuries– C-spine
![Page 5: Maxillofacial Trauma](https://reader036.vdocuments.us/reader036/viewer/2022062518/56813ff0550346895dab032f/html5/thumbnails/5.jpg)
Airway
• The potential for obstruction is present in almost all patients with significant facial injuries, due to pooling of blood and secretions in the pharynx, especially when supine.
• In most conscious patients this is simply swallowed – but will collect in the stomach.
• However, with midface fractures, particularly fractures of the mandible, swallowing may be painful and less effective in clearing the airway.

Airway
• In the acute setting use an oral tube
• Allows access for oral and nasal packing
• Subsequent tracheostomy or submental intubation

Sitting up
• This may indicate a desire to vomit, or unrecognised partial airway obstruction from swelling, loss of tongue support, or bleeding.
• Patients may try to sit forwards and drool, thereby allowing blood and secretions to drain

Maxillofacial Haemorrhage
• Bleeding following facial trauma may be either revealed or concealed
• In major midface and panfacial injuries blood loss can quickly become significant
• In these patients, blood loss is usually from multiple sites along the fracture planes and from associated soft tissues, rather than from a named vessel
• This makes control of bleeding difficult.
![Page 11: Maxillofacial Trauma](https://reader036.vdocuments.us/reader036/viewer/2022062518/56813ff0550346895dab032f/html5/thumbnails/11.jpg)
Maxillofacial Haemorrhage
• Direct pressure, clips and sutures may all be used to control obvious external bleeding
• When displaced midface fractures are present, manual reduction not only improves the airway, but is frequently effective in controlling blood loss from the fracture sites

Manual Reduction
![Page 13: Maxillofacial Trauma](https://reader036.vdocuments.us/reader036/viewer/2022062518/56813ff0550346895dab032f/html5/thumbnails/13.jpg)
Maxillofacial Haemorrhage
• Once reduced oral packing (or a mouth prop) can be used to support the reduction
• Multiple throat packs or vaginal packs can be used to pack the oral cavity
![Page 14: Maxillofacial Trauma](https://reader036.vdocuments.us/reader036/viewer/2022062518/56813ff0550346895dab032f/html5/thumbnails/14.jpg)
Maxillofacial Haemorrhage
• Epistaxis, either in isolation or associated with midface fractures may be controlled using a variety of nasal balloons, or packs.
• Rapid rhino packs provide effective haemostasis in most cases
• Urinary catheters can be passed and wedged into the post-nasal space for posterior bleeding

Rapid Rhino
![Page 16: Maxillofacial Trauma](https://reader036.vdocuments.us/reader036/viewer/2022062518/56813ff0550346895dab032f/html5/thumbnails/16.jpg)
Key Issues
![Page 17: Maxillofacial Trauma](https://reader036.vdocuments.us/reader036/viewer/2022062518/56813ff0550346895dab032f/html5/thumbnails/17.jpg)
Key Issues
• The nasal passage goes straight back not up
• Judgement is required with pan facial injuries due to the risk of cranial intubation.
• In patients with profuse haemorrhage a risk/benefit analysis is needed
![Page 18: Maxillofacial Trauma](https://reader036.vdocuments.us/reader036/viewer/2022062518/56813ff0550346895dab032f/html5/thumbnails/18.jpg)
Key Issues
• With unstable midfacial fractures - inflation of the balloons may displace the fractures thereby increasing blood loss.
• Temporary stabilisation of the reduced fractures prior to inflation– Pack the oral cavity prior to packing the nasal
cavity– Often mandibular fractures require surgical
stabilisation

Ongoing Bleeding
![Page 20: Maxillofacial Trauma](https://reader036.vdocuments.us/reader036/viewer/2022062518/56813ff0550346895dab032f/html5/thumbnails/20.jpg)
Coagulopathies
• In the presence of persistent haemorrhage, despite appropriate interventions, remember to consider coagulation abnormalities– Pre-existing (haemophilia, chronic liver
disease, Warfarin therapy),– Acquired (e.g. dilutional coagulopathy from
blood loss, or DIC).

Embolisation
• Effective alternative to surgical ligation in life-threatening facial haemorrhage
• Catheter-guided angiography followed by embolisation involving: balloons, stents, coils, or chemicals.
• Supra-selective embolisation can be performed without the need for a general anaesthetic and, in experienced hands, is relatively quick

Embolisation
![Page 23: Maxillofacial Trauma](https://reader036.vdocuments.us/reader036/viewer/2022062518/56813ff0550346895dab032f/html5/thumbnails/23.jpg)
Embolisation

Surgical Intervention
• If bleeding continues despite reduction of facial fractures and packing
• Ligation of the external carotid, and ethmoidal, arteries, via the neck and orbit, respectively should be considered
• Extensive collateral supply exists so ligation may not work or may be necessary on both sides
