Table 2. Different treatment options combined with the indication and the rate of cases that became symptom-free.

Therapy for sialolithiasis (number of treated patients)	Indication	Rate of symptom-free cases
Sialogogue and salivary gland massage ( n  = 5)	Conservative treatment regimen as the first step in a graded therapy	80%
Removal by endoscopy +/− papillotomy ( n  = 7)	Failed conservative treatment; intraductal location of the stone (stone < 5 mm)	71%
Transoral surgical removal ( n  = 18)	Intraductal location of the stone (stone > 5 mm)	67%
Extracorporeal shock wave lithotripsy (ESWL) ( n  = 2)	Intraparenchymal location of the stone	100%
ESWL prior to transoral surgical removal ( n  = 2)	Intraparenchymal location of the stone, intraductal location of the stone after ESWL	100%
ESWL prior to endoscopy and papillotomy ( n  = 1)	Intraparenchymal location of the stone, intrapapillary location of the stone after ESWL	100%
Submandibulectomy ( n  = 1)	Two failed attempts at transoral surgical removal	100%
Therapy for juvenile recurrent parotitis (number of treated patients)	Indication	Rate of symptom-free cases
Sialogogue, salivary gland massage, ibuprofen ( n  = 23)	Conservative treatment regimen as the first step in a graded therapy	83%
Antibiotics ( n  = 6)	Clinical signs of bacterial superinfection	83%
Sialendoscopy with lavage and predinosolone ( n  = 15)	> 5 episodes per year	53%
Therapy for acute sialadenitis (number of treated patients)	Indication	Rate of symptom-free cases
Sialogogue, salivary gland massage, ibuprofen ( n  = 5)	Mild symptoms without clinical signs of bacterial infection	100%
Per os antibiotics ( n  = 14)	Clinical signs of bacterial infection	100%
Intravenous antibiotics ( n  = 10)	No improvement following oral antibiotics	100%
Intravenous antibiotics  + intravenous prednisolone ( n  = 3)	No improvement following oral antibiotics and more severe clinical picture	100%

Note: Concerning the rate of symptom-free cases, the values represent the percentage of each evaluated subgroup.
