Clinical and Histological Features of Chorda Tympani Tumors

Abstract: Tumors of the chorda tympani are extremely rare. To date only 15 cases have been reported in the literature. Slow growing rate and nonspecific clinical features allow these lesions to reach a large size and resemble more common otological entities such as cholesteatoma. Diagnosis is usually established after surgical resection. However, lack of specifity of conventional pathological studies emphasizes the importance of immunohistochemical studies for final diagnosis. It is advisable to use the correct terms wh… Show more

“…Since facial paralysis is rarely appreciated in initial presentation and is mainly seen due to the mass pressure effect on the facial nerve itself; some authors advocate CTS as a distinct subgroup of facial nerve schwannomas ( 6 , 7 ). Accordingly, asymptomatic CTS cases have been reported in the literature ( 2 ). Our patient had facial paralysis and purulent ear discharge in presentation, however, we believe such a small tumor was unlikely responsible for the facial paralysis.…”

“…Schwannomas are the most common tumors of the facial nerve in the middle ear cleft. They can arise from any segment of the facial nerve or its branches ( 1 ).Although isolated chorda tympani schwannomas (CTS) are extremely rare, there are several reported cases in the English literature ( 2 , 3 , 4 ). The presented case is an incidental CTS identified during middle ear surgery for chronic otitis media.…”

“…Ambos exámenes son complementarios para planificar la cirugía y permitir una resección completa y segura del tumor 1 . Histológicamente son tumores caracterizados por un crecimiento fusiforme con áreas Antoni A y B alternantes, con S-100 positivo en la inmunohistoquímica [5][6] . El objetivo del tratamiento en los pacientes con SNF debe intentar preservar la función del nervio facial por el mayor tiempo posible.…”

“…La cirugía y reparación del nervio es el tratamiento de elección en pacientes con alteración de la función nervio facial de grado ≥III de House-Brackmann (HB). En casos excepcionales de SNF en pacientes asintomáticos, o sin compromiso del nervio facial (HB grado I o II), se prefiere la observación [4][5][6][7] . En dos de nuestros casos clínicos se decidió una resolución quirúrgica, dada la sintomatología de los pacientes y la imposibilidad de excluir otros diagnósticos.…”
