In our study population, the lifetime incidence of DCI was increased in divers with less diving experience. If further studies confirm this finding, diving federations should be encouraged to intensify their efforts of educating divers and should limit diving time and depth in inexperienced divers.
The results of this pilot study are encouraging, showing that preoperative tumor marker investigation in saliva from parotid glands is feasible and merits further investigation. CA 19-9 might be a valuable new diagnostic tool in the preoperative differentiation between malignant and benign parotid tumors and should be investigated in a larger number of patients.
