Surgical Techniques for the Management of Submandibular Salivary Duct Strictures

Sialoendoscopia y abordaje mixto para el manejo de la patología obstructiva de las glándulas salivales

Introducción. La sialoendoscopia es un procedimiento cuya finalidad es visualizar los conductos salivales. Se utiliza como método diagnóstico y terapéutico de procesos inflamatorios, estenosis de los conductos y procesos obstructivos. Métodos. Describir los procedimientos realizados para el tratamiento de pacientes con patología inflamatoria y obstructiva de las glándulas salivales, de forma única con sialoendoscopia o con abordajes mixtos. Resultados. Un total de 24 pacientes fueron incluidos en el estudio, con edad promedio de 42 años, en su mayoría mujeres y compromiso submaxilar en 58,3 % y de parótida en 41,7 %. Respecto a la intervención, al 29,2 % de los sujetos se le realizó extracción de cálculos, al 29,2 % sialoplastia, al 25 % dilatación de conductos y al 37,5 % lavado de conductos en el mismo momento quirúrgico. Conclusión. La sialoendoscopia y el abordaje mixto es un procedimiento que puede garantizar el manejo de patologías obstructivas y estenosis de los conductos salivales, con buen pronóstico y resultados, preservando la glándula y evitando las complicaciones de la cirugía.

Acute Submandibular Sialadenitis

Sialadenitis is a stone in the salivary system that often presents as acute pain and swelling and can cause significant distress to patients. Here, we present a case of submandibular sialadenitis in a 41-year-old woman who experienced sudden-onset facial and neck pain and swelling. In addition, we discuss the diagnosis and emergency department management.

Sialendoscopy: A Four-Year Single Center Experience

PURPOSE

Sialendoscopy is a relatively new technique designed to diagnose and treat benign obstructive salivary gland disease using a minimally invasive approach. The purpose of this study is to present our experiences regarding the use of sialendoscopy in the form of a 4-year, single center experience and to demonstrate its usefulness in oral and maxillofacial practice.

METHODS

We collected data on patients who underwent sialendoscopy at the Oral-Maxillofacial Surgery Department of UZ Leuven between November 2015 and August 2019, including age, gender, sex, initial clinical presentation and symptoms, gland involvement, type of diagnostic investigations, diagnosis, localization of the obstruction, therapeutic intervention, surgeon, type of anesthesia, materials used, complications, secondary treatment, duration of follow-up, and outcome. Statistical analyses were performed, chi-squared was used to compare the different variables with P < .05 being considered significant.

RESULTS

During the 4-year timeframe, a total of 44 patients (31 female, 13 male) underwent sialendoscopy in a total of 47 procedures. The average age at time of sialendoscopy was 47.4 years. The most frequent cause of obstruction was sialolithiasis (70%). Cone-beam computed tomography (CBCT) was the most accurate preoperative investigation for the diagnosis of lithiasis (57%). Symptom improvement occurred in 57.9% of patients, with a complication rate of 11%. None of the complications were permanent.

CONCLUSION

Sialendoscopy can be considered safe and effective for both the diagnosis and treatment of benign obstructive salivary gland disease, with a useful place in oral and maxillofacial surgical practice. We recommend the inclusion of CBCT and/or ultrasound in the diagnostic workup prior to endoscopy.
