[Surgical policy in patients with basally advanced form of juvenile nasopharyngeal angiofibroma].
The authors has modified surgical policy in a basicranially extending form of juvenile nasopharyngeal angiofibroma (JNA) which is classified into tumors of stage I, II and III. Basally advanced tumors were diagnosed in 28 of 40 JNA patients: basicranially extended tumor (n=12, 30%), stage I tumor invading nasopharynx, nasal cavity, sphenoid sinus (n=4, 14.3%), stage II tumor invading nasopharynx, nasal cavity, sphenoid sinus, pterygopalatine fossa, ethmoid sinuses (n=9, 32.1%), stage III tumor invading nasopharynx, nasal cavity, sphenoid sinus, pterygopalatine fossa, ethmoid sinuses, infratemporal fossa, orbit, maxillary sinus and parapharyngeal space (n=15, 53.6%). Differential surgical treatment according to Owens (stage I tumors), Denker (stage II tumors), Moure (stage III tumors) provides radical removal of the tumor in the majority of the patients (87.7%) and therefore is an effective therapy of surgical treatment of the above patients.
