ABSTRACT

The aim of the study was to demonstrate a novel transoral parapharyngeal approach to the submandibular space. The method used was the clinical case of a patient presenting with an anteriorly based tumor in the left submandibular space. The video shows the transoral robotic technique for access to the submandibular space through the parapharyngeal space for removal of the tumor. This approach allows for high definition visibility and complete access to structures in the submandibular space including the submandibular gland. For robotic head and neck surgeons performing lateral oropharyngectomies, the anatomy is familiar, and the technique avoids potential access issues with traditional floor of mouth incisions. Furthermore, it provides a novel technique for identification of the hypoglossal nerve for potential preservation in oropharyngeal malignancy. The transoral robotic parapharyngeal approach to the submandibular space is safe, reproducible, and avoids unnecessary cervical incisions.

ABSTRACT

Antecedentes: el carcinoma adenoquístico es el tumor maligno más frecuente de las glándulas sub-maxilar y menores. A pesar de su lento crecimiento y diseminación regional, muestra un pronóstico desfavorable debido a su tardía diseminación a distancia. Objetivo: analizar la serie propia a la luz de la bibliografia. Material y métodos: 44 pacientes con una edad media de 52,47 años y predominio del género femenino. De ellos, el 61,3% fueron tumores de glándula salival menor, 20,4% de submaxilar y 18,2% de parótida. En todos se realizó resección completa del tumor, seguida de vaciamiento cervical en el 34%. En el 43,2%, la cirugía fue seguida de Co60 radioterapia. El seguimiento medio de la muestra fue 52,5 (1-120) meses. Resultados: la curva de recurrencia acumulada fue del 36,8% a 5 años. La supervivencia global fue del 60 y 36% a 5 y 10 años, respectivamente, y se vio afectada con significación estadística por los márgenes insuficientes de la resección, el requerimiento de radioterapia adyuvante y el estadio. El análisis multivariado demostró que solo los márgenes insuficientes conservaron su significación estadística para la supervivencia y una tendencia desfavorable para el intervalo libre de enfermedad. Conclusiones: la extensión de la cirugía al cuello y la radioterapia adyuvante dependieron del estadio, los márgenes quirúrgicos, el compromiso nervioso, la presencia de adenopatas positivas y el subtpo histológico.


Background: adenoid cystic carcinoma is the most frequent malignant tumor of submaxillary and mi-nor salivary glands. Despite its slow growth, it shows an unfavorable prognosis because of its distant disseminaton. Objective: to analyse our series of patents in relaton to the literature. Materials and methods: 44 patents with mean age 52.47 years female gender. Of them, 61.3% were of minor salivary glands, 20.4% of submaxillary gland, and 18.2% the parotid gland. All patents underwent complete resecton of the tumor followed by neck dissecton in 34%. Co60 radiotherapy was administered to 43.2%. Mean follow up was 52.5 (range, 1-120) months. Results: 5-year recurrence rate was 36.8%. At 5 and 10 years, overall survival was 60 and 36%,respect-vely. Close surgical margins, requirement of adjuvant radiotherapy and stage significantly afected survival rate. The multivariate analysis showed that close margins was statstically significant for survival and associated with an unfavorable tendency for disease-free interval. Conclusions: extenton of surgery to the neck and adyuvant radiotherapy was dependent of stage, clear surgical margins, neural invasion, positive nodes in the neck and hystological subtype.
