Summary
Jet pilots show increased paranasal sinus inflammation after training. A prominent ethmoidal bulla is linked to ostiomeatal complex obstruction in these aviators.
Area of Science:
- Aerospace Medicine
- Otolaryngology
- Radiology
Background:
- Jet aircraft pilots face significant pressure variations impacting physiological systems.
- Respiratory system functions, including paranasal sinuses, may be affected by flight conditions.
Purpose of the Study:
- To evaluate inflammatory changes in jet pilots' paranasal sinuses before and after training using CT.
- To compare sinus inflammation in pilots versus non-airborne individuals.
- To assess the link between ostiomeatal complex (OMC) obstruction and anatomical variations.
Main Methods:
- Multislice computed tomography (CT) was used for evaluation.
- 15 jet aircraft pilots and 41 non-airborne controls were studied.
- Pilots were assessed pre- and post-training program.
Main Results:
- Jet pilots exhibited higher rates of mucosal thickening in the maxillary sinus and anterior ethmoid cells compared to controls.
- A significant association was found between a prominent ethmoidal bulla and OMC obstruction.
Conclusions:
- Jet aircraft pilots demonstrate a higher prevalence of inflammatory sinus disease than non-airborne individuals.
- Prominent ethmoidal bulla is identified as a risk factor for OMC obstruction in pilots.

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

01:29Anatomy of Respiratory System I: Upper Respiratory Tract
1.4K
The upper respiratory tract plays a vital role in the respiratory system, comprising several structures that facilitate air intake and prepare air for the lungs. It also serves as the first line of defense against pathogens and particles. This tract includes the nose and nasal cavity, the oral cavity, the paranasal sinuses, and the pharynx, each with specific functions and features.

01:27Cranial Bones: Lateral View
2.2K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:24Nose and Nasal Cavity
2.3K
The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...
