Sialolitiasis submandibular gigante, extracción quirúrgica y reparación ductal: reporte de caso / Giant submandibular sialolithiasis, surgical removal and ductal repair: case report

Introducción: la patología litiásica de las glándulas salivales forma parte de un grupo de afecciones que perjudica el sistema de drenaje normal de la saliva hacia la cavidad oral, ocasionando lesiones múltiples sobre la glándula afectada. Se realizó el reporte de un caso clínico con esta patología que, por el tamaño del lito, se considera extremadamente rara en nuestro medio. Método: se realizó el reporte de caso y revisión de la literatura (estudios radiológicos, historia clínica y hallazgos clínicos); además, el paciente firmó el consentimiento para esta publicación. Resultados: un paciente masculino de 38 años remitido de consulta externa con un cuadro clínico de 1 semana de dolor, edema y tumefacción en la región submandibular izquierda asociado con una secreción sialopurulenta por la cavidad oral. En la radiografía (Rx) oclusal estricta y en la tomografía axial computarizada (TAC) de cuello contrastado se evidenció una lesión litiásica de más o menos 4,5 x 1,8 cm de diámetro, de característica radiolúcida, a nivel del conducto de wharton. Se dio un manejo quirúrgico por otorrinolaringología maxilofacial, consistente en sialolitotomía y antibioticote- rapia por 10 días, con las cuales se obtuvieron buenos resultados. Conclusiones: la litiasis gigante a nivel del sistema salival (glándula, conductos) es una patología poco común en nuestro medio y está involucrada en el desarrollo de múltiples patología de tipo inflamatorio recurrente de la glándula involucrada, lo cual afecta la calidad de vida de los pacientes. Por esta razón, el diagnóstico y manejo debe ser oportuno para evitar complicaciones, como una infección profunda del cuello; en nuestro caso, el manejo fue oportuno con una extracción quirúrgica por la vía oral del cálculo y la reparación del conducto de wharton del lado izquierdo.

Introduction: the lithiasic pathology of the salivary glands is part of a group of conditions that harms the normal drainage system of the saliva towards the oral cavity, causing multiple lesions on the affected gland, a report of a clinical case with this pathology was made. Due to the size of the stone it is considered extremely rare in our environment. Method: case report and review of the literature (radiological studies, clinical history, clinical findings) patient consent was signed for this publication. Results: a 38-year-old male patient referred from the outpatient clinic with a 1-week clinical picture of pain, swelling and edema in the left submandibular region associated with sialopurulent secretion from the oral cavity in the strict occlusal Rx and a contrast-enhanced neck CT revealed a lithiasic lesion with more or less 4.5 x 1.8 cm in diameter of radiolucent features at the level of the wharton duct, surgical management was given by maxillofacial ENT, consisting of sialolitotomy and antibiotic therapy for 10 days with good results. Conclusions: the giant lithiasis at the level of the salivary system (gland, ducts) is a rare pathology in our environment, is involved in the development of multiple pathologies of recurrent inflammatory type of the affected gland, affecting the quality of life of patients, so the diagnosis and management should be timely and avoid complications, such as deep neck infection; in our case, the management was timely with oral surgical removal of the calculus and repair of the wharton duct on the left side.

Clinical, statistical and chemical study of sialolithiasis

INTRODUCTION: Sialolithes are initiated by localized deposition of calcified material in the salivary glands. And that may even cause various symptom especially swelling and pain. This study purposes to collect statistical data of sialolithiasis for clinical analysis. MATERIALS AND METHODS: Among forty seven patients who have visited Seoul National University Dental Hospital during 2004-2009, patients' age, sex, location and size of stone, radiodensity of stone, symptom, surgical procedure were investigated. Statistical correlation between size, location, symptom was evaluated. Chemical composition was analyzed for 3 sialolithes. RESULTS: The average age was 41.4 years. Sialolithiasis had slight female predilection (57.4%). Most cases occurred in the submandibular glands (91.5%). And most cases had radiopaque features (95.8%). The average size was 7.17 mm. The most frequent location of the stones were the duct orifice and the submandibular gland hilum (16 cases in each), followed by the middle part of the duct (n=8), the intraglandular area (n=4), and the proximal part of the duct (n=3). Eleven cases were asymptomatic. Thirty six cases had complaints of pain, swelling, hardness, and decrease in saliva flow (multiple symptoms). Various methods of surgery was performed. Two cases were self-removed. Thirty seven cases underwent procedure involving stone removal alone. Six cases underwent gland extirpation, and two cases underwent ductoplasty. CONCLUSION: There was no statistical correlation between size, location, and symptoms. Sialolith was composed of Ca (58.5-69.3%), P (30.7-35.7%), organic material, and trace inorganic material.
