Scuba diving is known to affect the rhino-pharyngo-tubaric district (RPT unit). The aim of the study was to document function modifications of the RPT unit in 6 Italian divers (3 men and 3 women) who lived for 14 days consecutively at a depth of 8-10 m, breathing air (21% oxygen) at a pressure ranging between 1.8 and 2 ATA. RPT and inner ear assessment were carried out before the dive (TIME 0) and 24 h (TIME 1) after resurfacing, in order to investigate diving-related RPT and inner ear alterations. Physical examination after resurfacing revealed: fungal external otitis, otoscopic findings consistent with middle ear barotraumas and rhinosinusitis. Rhino-manometry showed a remarkable increase in inspiratory nasal flow and a substantial decrease in nasal resistance. No epithelial cell disruption was retrieved comparing pre and post resurfacing samples. Post-diving tubaric dysfunction was found. Pure tone audiometry revealed a bilateral 40 dB HL hearing loss at 4 kHz in 1 diver. Relevant PTA functions did not seem to be affected by the experiment, no remarkable changes were found at the Sensory Organisation Test and at the Motor Control Test.

Abstract

Scuba diving is known to affect the rhino-pharyngo-tubaric district (RPT unit). The aim of the study was to document function modifications of the RPT unit in 6 Italian divers (3 men and 3 women) who lived for 14 days consecutively at a depth of 8-10 m, breathing air (21% oxygen) at a pressure ranging between 1.8 and 2 ATA. RPT and inner ear assessment were carried out before the dive (TIME 0) and 24 h (TIME 1) after resurfacing, in order to investigate diving-related RPT and inner ear alterations. Physical examination after resurfacing revealed: fungal external otitis, otoscopic findings consistent with middle ear barotraumas and rhinosinusitis. Rhino-manometry showed a remarkable increase in inspiratory nasal flow and a substantial decrease in nasal resistance. No epithelial cell disruption was retrieved comparing pre and post resurfacing samples. Post-diving tubaric dysfunction was found. Pure tone audiometry revealed a bilateral 40 dB HL hearing loss at 4 kHz in 1 diver. Relevant PTA functions did not seem to be affected by the experiment, no remarkable changes were found at the Sensory Organisation Test and at the Motor Control Test. The 14-day underwater period had a positive effect on nasal flows and resistances.
