Treatment of allergyĪ treatment was put in place by the doctor. It’s therefore a barotrauma triggered by an undetected allergic reaction until this dive. On leaving the sinus, the polyp also compressed the under orbital trigeminal nerve (the one that innervates a part of the cheek and the teeth of the upper jaw) and caused the pain and anesthetized teeth. The polyp was so good out that the ENT saw it in the nasal cavity! This polyp, when the air wanted to leave the sinus during the ascent, obstructed the sinus canal. So here it is: a polyp probably of allergic origin! No improvement …ĭaniel then goes to his ENT specialist which makes him various tests that will reveal sinusitis in the left maxillary sinus and the presence of a polyp. He then went to a specialist in maxillofacial dentistry who diagnoses sinusitis and prescribes antibiotics. The air must come out by any means, if it is necessary the sinus will break!ĭaniel goes to see his dentist who excludes a dental problem. This doctor reports that he already had divers with a fractured sinus after this kind of incident Looks like a mechanical proglem not allergy. And that the air in the sinus (first compressed by the descent and decompressed during the ascent) can not get out of the sinus. He phones DAN to talk to a doctor dealing with hyperbaric medicine.įor this specialist, it is possible that the sinus canal (from the maxillary sinus to the nasal cavity) is obstructed. The next day, Daniel still has an insensitive jaw. In search for the cause, could allergy be the cause ? His instructor advises him to check with his dentist because he is not a doctor and he has never had the case despite thousands logged dives. No more nausea or pain but still this insensitive jaw. The pain fades away gradually, Daniel regain colors and paracetamol helps him to reduce the pain. Even if at this time and given the dive profile nobody associates the problem with a decompression accident. To make sure, the instructor offers him to take oxygen for 30 minutes and paracetamol asking him if he has no allergy to paracetamol. Indeed, everyone sees that Daniel is actually “not well at all”. He informs his instructor of what he feels. The pain rather than disappearing, spreads over most of the left hemiface and Daniel feels nausea that he attributes to vagal discomfort caused by pain. Once out of the water and his gear removed. (as at the dentist) As well as the left cheek (internal and external face). He realizes that all his teeth of the upper left jaw are anesthetized. Back at the surface,Ībout twenty minutes after he started the dive. But at the passage of the tongue, no breakage in the teeth. He thinks that a tooth has cracked or broken. The instructor does not stay on the bottom very long and calmly starts the ascent following the gentle slope of the lake.Īt about 5-6 meters deep, Daniel feels a sharp pain in the upper left jaw (in the premolars). In order not to be cold (we are in Belgium anyway). He feels good and explores the site with his instructor to the expected depth. Everyone is getting ready happily and let’s go.ĭaniel discovers the aquatic world with gentleness and confidence. And constituting one of the points of interest of this lake. It is decided, that if Daniel feels comfortable in the zone of -10 m for this first training dive, they will evolve towards the wreck of a bus on this dive spot to a maximum depth of -17m. He is the most experienced of the instructors present and whom he trusts.Īs the privileges of their certification agency allow them. With his friends, they will be able to discover the joys of diving in open water.ĭuring the briefing, it is decided that Daniel will dive with his usual instructor.
