“…Many authors favor the transparotid transcervical approach for extirpating PPS PAs arising in the DLPG, [6], [11], [12] whereas others advocate the simple transcervical approach because it provides excellent local disease control with minimal risk for facial nerve injury [13]. Preoperative determination of tumor attachment to the DLPG can serve as a crucial criterion for guiding surgical management.…”

BackgroundHead and Neck Parapharyngeal space tumors are rare. Pleomorphic Adenomas are the most common Parapharyngeal space tumors. The purpose of this study was to define preoperative criteria for enabling full extirpation of parapharyngeal space pleomorphic adenomas via the transcervical approach while minimizing functional and cosmetic morbidity.MethodsThe surgical records and medical charts of 19 females and 10 males with parapharyngeal space pleomorphic adenomas operated between 1993 and 2012 were reviewed.ResultsFifteen patients were operated by a simple transcervical approach, 13 by a transparotid transcervical approach, and one by a transmandibular transcervical approach. Complications included facial nerve paralysis, infection, hemorrhage and first bite syndrome. There were three recurrences, but neither recurrence nor complications were associated with the type of surgical approach.ConclusionA simple transcervical approach is preferred for parapharyngeal space pleomorphic adenomas with narrow attachments to the deep lobe of the parotid gland and for pleomorphic adenomas originating in a minor salivary gland within the parapharyngeal space.

“…Symptoms are usually subtle and late because of the deep location in the neck; PPS tumours become clinically detectable when their size achieves a diameter of 2-3 cm. The growing tumour determinates a specific symptoms, which include a visible parotid swelling, oropharyngeal swelling, dysphagia, dyspnoea, and nasal obstruction [14]. …”

Malignant peripheral nerve sheath tumour (MPNST) is extremely rare malignancy in the general population, occurring more frequently in patients with Neurofibromatosis type 1 (NF1). In the literature five cases of MPNST arising from the parapharyngeal space (PPS) in patients without neurofibromatosis have been reported. We report imaging techniques in a patient with MPNST in the PPS, who had neither a family history nor sign of NF1. Computed tomography (CT) scan and magnetic resonance imaging (MRI) were performed for a correct therapeutic planning. CT and MRI findings were correlated with hystopathological diagnosis.

“…El tumor que más frecuentemente asienta en el espacio parafaríngeo es el adenoma pleomorfo de la glándula salival 3 . La RM, la TC y la punción-aspiración con aguja fina (PAAF) son pruebas complementarias útiles para determinar la posible etiología y la extensión a estructuras vecinas.…”

Mujer de 56 años de edad sin antecedentes médico-quirúrgi-cos de interés que consulta por dolor en la región temporomandibular izquierda extendido a la región maxilar ipsilateral de un año de evolución.Clínicamente refiere dolor a la palpación de la ATM izquierda, es bruxista y parece tener un síndrome miofascial asociado en relación a la musculatura pterigoidea. Presenta dolor a punta de dedo en el maxilar superior izquierdo. Tras tratamiento conservador con fármacos antiinflamatorios, analgésicos y una férula de reposicionamiento condilar, la paciente experimentó una leve mejoría clínica de la patología miofascial pero seguía aquejando la molestia maxilar, por lo que se decidió pedir una resonancia magnética (RM). En dicha prueba se visualiza una masa que es informada como "lesión ocupante de espacio a nivel parafaríngeo izquierdo, de contornos bien definidos, hipointensa en T1 e hiperintensa en T2" ( fig. 1).Ante el hallazgo radiológico, se decide completar el estudio con una tomografía computarizada (TC), en la que se aprecia una pequeña lesión hipodensa sin realce, de aproximadamente 16 × 13 × 17 mm, que se sitúa por delante de la apófi-sis estiloides izquierda, adyacente y medial al lóbulo profundo de la glándula parótida izquierda, improntando en sentido anterior y medial a la grasa parafaríngea. No existe extensión a la base del cráneo.No se palpan masas cervicales ni se observan adenopatías clínico-radiológicas. Tampoco existía focalidad neurológica en relación a pares craneales.No hay signos clínicos infecciosos, y las analíticas aportadas por la paciente son normales.Debido a la localización pre-estílea, se realiza punción guiada por TC ( fig. 2) y se envía la muestra a anatomía patoló-gica.
