Abstract

Sialolithiasis is the most common pathology in the submaxillary gland. The introduction of minimally invasive techniques isolated or associated with sialoendoscopy is replacing glandular resection as a treatment. The conservation of the gland is justified by the recovery of function and a low recurrence rate. The rate of complications is lower in conservative techniques than in submandibular gland resection. Thirty-three patients with fixed stones in the hilum of the submaxillary gland were treated by transoral sialolitectomy between July 2015 and July 2018, demographic data of the patients such as the number of stones, size, time of hospital stay, complications, pre- and postoperative lingual nerve function, and lithiasis recurrence were collected. The average volume of the stones was 1.02 cm. Complete removal of the stone was possible in 32 patients. All the patients were operated in the outpatient clinic. Seven (21%) patients reported some degree of alteration of the lingual nerve function, of which the only one presented a persistence of more than 4 weeks due to an inadvertent injury that required a microsurgical anastomosis. Transoral sialolitectomy is a reproducible technique with good results and lower complication rates than submandibular gland resection. Our results in the first 33 cases encourage us to maintain the combined techniques as standard in the treatment of submaxillary sialolithiasis. Current experience guides the definitive substitution of submandibular gland resection by conservative techniques in obstructive pathology.
