Ear, nose and throat barotrauma are the most frequently encountered accidents during diving. One study related to recreational diving reports that ENT barotrauma concern 10% of dives with experimented divers and 30% with novice divers. Nevertheless, a low number of studies were realized on ENT barotrauma, particularly those involving middle ear and sinuses, maybe because most of them evolve favorably without sequelae.
Besides, it has been described that pathologies which may induce chronic or acute tubal dyspermeability can result in an increased middle ear or sinus barotrauma risk. But once again no study was realized which objective was to look for an association between these risk factors and for the association strength between risk factors and ENT barotrauma occurrence. Few data on military population exist either. However, operational constraints, stressing environment with necessity of realizing performances to validate diving certificate or other military diving specificities can lead one to think that military divers have an increased risk to be subjected to ENT barotrauma. Furthermore, therapeutic measures and more particularly physicians' attitude concerning a temporary incapacity period to avoid recurrence or clinical worsening of barotrauma differ depending on diving centers. But the question to resume diving or not is essential for military staff given that temporary incapacity may lead to training cessation or can be questioned because of operational constraints requiring anticipated diving resumption.
The purpose of this research is to study middle ear and sinus barotrauma thanks to questionnaires focused on those pathologies and their potential risk factors. The hypothesis is that it will allow identification of main risk factors in order to develop preventive measures as well as the characteristics and missions of concerned divers and the impact of those barotrauma on this population.

Futhermore, few data on military population exist while operational constraints, stressing environment with necessity of realizing performances to validate diving certificate or other military diving specificities can lead one to think that military divers have an increased risk to be subjected to ENT barotrauma.

The aim of this research is then to study middle ear and sinus barotrauma in order to identify main risk factors, the characteristics and missions of concerned military divers and the impact of those pathologies on this population. Two kind of questionnaires will be used : one which will be completed by divers just after their inclusion in the study and one that will be filled in case of ENT barotrauma suspicion over a period of two years. The first questionnaire will give information about diving level and medical history and the second one will allow standardized assessment of barotrauma suspicion . Divers will be followed for two years, whether they experience an ENT barotrauma or not.

| ENT Barotrauma incidence among French army divers and student divers followed for 2 years | Number of ENT barotrauma occurring among French army divers and student divers enrolled in the study for 2 years. Characteristics of concerned divers (diving level, medical history…) will also be presented. ENT Barotrauma events will be defined according to Haines and Harris classification after otoscopic examination for middle ear and by sinus pain sudden onset during diving for sinuses. Clinical confirmation will be obtained through questioning and suggestive disease history. In case of doubt, a scanner will be used. | 4 years |

| Correlation between ENT barotrauma and divers characteristics | Correlation will be performed between ENT events and characteristics of enrolled divers (diving level, dive kind, medical history…) to determine if one these characteristics constitutes a risk factor | 4 years |
