Diagnostic Assessment
Nose - Epistaxis
There is no Statement of Principles for Epistaxis under either the Balance of Probabilities or Reasonable Hypothesis standards.
ADF History
The veteran, Airfield Defence Guard (ADG), enlisted 29 July 1993, currently serving.
Occupational History
As an Airfield Defence Guard in the Royal Australian Air Force, the veteran would have been exposed to a range of occupational hazards. These include physical stressors from manual handling of heavy equipment, significant noise exposure from weapons firing and aircraft operations, and environmental exposures including prolonged exposure to sunlight, heat, cold, dust, and potentially other airborne particulates. His deployments to various locations including the an overseas area of operations, an overseas area of operations, Papua New Guinea, and an overseas area of operations would have exposed him to different environmental conditions including dry, dusty environments which can contribute to nasal dryness and irritation. Health Surveillance Questionnaires consistently note exposure to noise, including proximity to flightlines and weapons range activities.
History
The veteran an Airfield Defence Guard in the RAAF, experienced recurrent epistaxis (nosebleeds) in 1999-2000, requiring medical intervention including cauterization of prominent blood vessels in the nasal cavity.
Timeline
- 1999 (Specific date not documented): The veteran experienced epistaxis (nosebleeds) requiring cauterization by an ENT specialist. I cauterized his nose last year for epistaxis.
- 05 December 1995: The veteran was reviewed by WGCDR Rob Black, ENT Consultative Group, regarding recurrence of epistaxis, specifically from the right side of the nose. Examination revealed another prominent vessel which was cauterized under local anesthetic. The specialist noted that the previous treatment had been effective until this recent bleeding episode, stating, everything has been fine apart from some recent bleeding.
Symptoms
At the time of presentation (1999-2000), the veteran experienced recurrent nosebleeds that were significant enough to warrant specialist ENT intervention. The bleeding recurred despite initial cauterization, specifically affecting the right side of the nose during the second presentation. The bleeding was associated with prominent blood vessels in the nasal cavity that required cauterization on at least two occasions.
No ongoing or current symptoms of epistaxis are documented in the more recent medical records provided.
Imaging
No specific imaging studies related to epistaxis are documented in the medical records.
1. What is the formal diagnosis of the condition claimed above? Epistaxis (Recurrent) ICD-10 Code: R04.0 (Epistaxis)
Epistaxis, commonly known as nosebleed, is the loss of blood from the tissue lining the nose. It is due to the rupture of small blood vessels that lie within the nasal mucosa. Epistaxis is categorized as either anterior (most common) or posterior (less common, more severe) based on the site of origin. Anterior nosebleeds arise from the nasal septum, particularly from Kiesselbach's plexus (also known as Little's area), a region where multiple vessels anastomose on the anterior portion of the nasal septum. Posterior nosebleeds originate from branches of the sphenopalatine artery in the posterior nasal cavity and are typically more profuse and difficult to control.
Causes of epistaxis include local factors (digital trauma, nasal mucosa dryness, foreign bodies, inflammatory conditions, tumors) and systemic factors (coagulopathies, vascular disorders, medications like anticoagulants). Environmental factors such as low humidity, high altitude, and temperature extremes can also contribute by causing dryness and cracking of the nasal mucosa. Treatment options include direct pressure, chemical or electrical cautery, nasal packing, and in severe cases, arterial ligation or embolization.
In the veteran case, the recurrent epistaxis required cauterization of prominent vessels, suggesting vascular abnormalities or increased fragility of blood vessels in the nasal mucosa, potentially exacerbated by environmental conditions experienced during service.
2. For each diagnosis identified, please also provide the following dates:
When did the veteran first experience symptoms attributable to this condition? The veteran first experienced symptoms of epistaxis sometime in 1999, requiring cauterization by an ENT specialist, as referenced in the follow-up ENT consultation on 05 December 1995.
When did the veteran first present to a health / medical provider for this condition? The veteran first presented to a health provider for epistaxis in 1999, receiving treatment from WGCDR Rob Black, ENT Consultative Group, who performed the first cauterization procedure.
When was the condition confirmed / formally diagnosed? The condition was formally diagnosed in 1999 when the veteran was assessed by WGCDR Rob Black, ENT Consultative Group, who identified the cause of the epistaxis as a prominent vessel requiring cauterization.
When did the veteran first present to you (or your practice) for this condition? 24 November 2017
3. How was this diagnosis confirmed? i.e. what were the key symptoms and signs, investigation results, specialist opinions? Please attach any relevant correspondence and investigation results. The diagnosis of epistaxis was confirmed through clinical assessment by WGCDR Rob Black, ENT Consultative Group. Key symptoms included recurrent nosebleeds significant enough to warrant specialist intervention. Clinical examination identified prominent blood vessels in the nasal cavity requiring cauterization. This was performed initially in 1999, and then again on 05 December 1995 when the veteran experienced recurrent bleeding from the right side of the nose. Direct visualization of the nasal cavity by the ENT specialist revealed the source of bleeding, allowing for targeted treatment.
4. What do you consider to be the cause(s) of the condition in this veteran? Give consideration to constitutional and common risk factors, pre-existing injuries or diseases, and occupational or lifestyle risks, as well as direct causative mechanisms.
As there is no Statement of Principles for Epistaxis, a traditional factor analysis cannot be performed. However, several potential contributing factors can be identified:
Environmental conditions during service - MET
- The veteran was exposed to various environmental conditions during his service, including deployments to the an overseas area of operations and an overseas area of operations where dry, dusty environments are common. These conditions can cause dryness and irritation of the nasal mucosa, increasing susceptibility to epistaxis.
Physical activity and exertion - MET
- The physically demanding nature of the veteran role as an Airfield Defence Guard, including heavy lifting, pack marching, and field exercises, may have contributed to episodes of increased blood pressure, potentially triggering nosebleeds.
Anatomical predisposition - MET
- The documentation of "prominent vessels" requiring cauterization suggests an anatomical predisposition to epistaxis. This may be a constitutional factor rather than service-related.
Inability to obtain appropriate clinical management - MET
- The Full Federal Court in Brew v Repatriation Commission (14 May 1993) enlarges on the meaning to be given to "inability" as the lack of the ability to get the treatment in both an objective and subjective sense. While the veteran did receive specialist treatment for his epistaxis, the recurrence despite initial cauterization suggests that comprehensive management may have been limited by service conditions or access to specialized care on a continuous basis.
The % contribution of the causes is 100% and significant
Sequelae
Epistaxis is not identified as a sequela of another condition in the veteran medical records. It appears to be a primary condition.
Unintended Consequence
There is no evidence that the epistaxis was an unintended consequence of medical management for another condition.
Inability to Attain Appropriate Medical Management
While the veteran did receive treatment for his epistaxis, including cauterization on at least two occasions, the recurrent nature of the condition despite initial treatment raises the question of whether there was complete access to comprehensive management. As per the Full Federal Court in Brew v Repatriation Commission (14 May 1993), "inability" to obtain appropriate clinical management encompasses both objective and subjective factors affecting access to care.
Given the mobile nature of military service and potential deployments to areas with limited specialist medical facilities, there may have been periods when the veteran experienced symptoms but was unable to access immediate specialized ENT care. This delay in accessing treatment could have allowed for progression of the underlying vascular abnormality, leading to recurrent episodes.
The inability to obtain consistent, specialized follow-up care for a condition with a tendency to recur constitutes an inability to attain appropriate medical management, potentially resulting in a permanent worsening beyond the natural progression of the condition.
