Sinus Barotraumas in Commercial Aircrew
Aerospace Medicine and Human Performance
|November 25, 2021
Summary
Sinus barotraumas affect 61% of commercial aircrew, leading to increased medical needs and sick leave. Female sex and frequent upper respiratory tract infections are identified risk factors for this aviation medicine concern.
Area of Science:
- Aviation Medicine
- Otolaryngology
- Occupational Health
Background:
- Sinus barotraumas pose a significant risk to flight safety and aircrew careers.
- The increasing volume of commercial aviation necessitates a comprehensive understanding of sinus barotraumas.
Purpose of the Study:
- To determine the prevalence of sinus barotraumas in commercial aircrew.
- To investigate the clinical characteristics, health, and occupational effects of sinus barotraumas.
- To identify risk factors associated with sinus barotrauma occurrence.
Main Methods:
- A survey study utilizing an anonymous electronic questionnaire distributed to commercial aircrew in Finland.
- The survey covered a substantial portion of the target population, achieving a 47% response rate.
- Data analysis included calculating prevalence and odds ratios for risk factors.
Main Results:
- 61% of surveyed aircrew reported experiencing sinus barotraumas during flight.
- Affected individuals frequently required medication (59%), surgical procedures (18%), and sick leave (53%).
- Female sex and a high frequency of upper respiratory tract infections were significantly associated with increased risk.
Conclusions:
- Sinus barotraumas are highly prevalent among commercial aircrew, impacting their health and ability to fly.
- The condition necessitates medical interventions and leads to significant sickness absence.
- Identifying female sex and frequent URTI as risk factors aids in targeted prevention strategies.

Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned...

Managing flail chest, a condition characterized by a segment of the chest wall moving independently from the rest of the thoracic cage, requires a comprehensive approach. It includes a thorough assessment of the patient's condition, a diagnostic evaluation to determine the extent of the injury, and the implementation of appropriate medical interventions tailored to the individual's needs.

Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.

Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...

A pneumothorax is a condition where air builds up in the space between the lung and the chest wall, causing the lung to collapse. This condition arises when air enters the space between the parietal and visceral pleura, disrupting the negative pressure essential for lung inflation. This can lead to a partial or complete collapse of the lung.
Pneumothorax can be even further classified as spontaneous, traumatic, and tension pneumothorax.

Overview of Flail Chest
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
