Zur Differentialdiagnose der parapharyngealen Raumforderung

Abstract

Mostly, parapharyngeal masses are represented by salivary gland tumors (40%-50%). The second most common tumors in the parapharyngeal space are neurogenic tumors (17%-25%). Paragangliomas are the third group of common parapharyngeal lesions (10%-15%). A mixed group of lesions like branchial cleft cysts, lymph nodes and hematogenic tumors represent the remaining part of the parapharyngeal masses (10%-33%). Most of the lesions (80%) are benign. Because of the magnetic response imaging a reliable preoperative diagnosis is possible in more than 80% of the tumors. The surgical management may also be influenced by the location of the tumor shown in the magnetic resonance imaging.

“…The biggest part (40-50%) of parapharyngeal masses is composed of salivary gland tumours, the second in [7]. Our experience coincides with data found in literature: majority of tumours originated from salivary gland tissue.…”

“…In such cases, cervical swelling and smooth submucosal mass that anteromedially displaces the lateral pharyngeal wall, tonsil, and soft palate, revealed by intraoral physical examination, are recognized by chance [2,7,16]. Often, previously mentioned masses are misdiagnosed for an infection or a tonsil tumour [2,16].…”

“…The treatment of choice is the surgical removal of the tumor, 1,2,4,7,10,16,20 and although various methods of approach are proposed (transoral, 2,29 transcervical with or without a mandibulectomy, 2,30 cervicoparotid, 18 transparotid, 31 or cervico-transpharyngeal), 18 most authors coincide as to the transcervical approach being the most appropriate, 2,10,20,32 and the one with better surgical results. 1 In certain cases such as with elderly patients or those with a systemic pathology where the use of anesthesia is contraindicated, in cases of tumors that cannot be resectioned or in cases of patients that will not accept the intraoperative morbidity that the surgery involves, treatment with radiotherapy can be opted for.…”

“…1,2 Aproximadamente el 80% presentan un comportamiento benigno. [2][3][4] La singularidad de dichas lesiones deriva de su compleja situación anatómica y de la clínica con la que suelen debutar, siendo en la mayoría de los casos inespecífica y casi siempre derivada del efecto compresivo producido por la lesión sobre oro y rinofaringe.…”
