Malignant Tumor of Nasal cavity and Paranasal sinuses ( p109 )

: Statistics: ENT: 20% in total Malignant Tumor. ENT: 20% in total Malignant Tumor. Nasal and sinonasal MT: 21.74% % in ENT MT. Nasal and sinonasal MT: 21.74% % in ENT MT. Male: female =3 ∶ 1 , predilection age: 40 ~ 60y. Male: female =3 ∶ 1 , predilection age: 40 ~ 60y.

Features: 1. predilection site is maxillary sinus(60 ~ 80%), 1/3 with ethmoid sinus MT. 2. ethmoid sinus>frontal sinus>sphenoid sinus. 3. primary tumor>>metastatic tumor. 4. advanced stage> primary stage 5. invasion of adjacent tissue( orbit, skull base)

Etiological factor Immunocompromice Immunocompromice Stimulation of chronic inflammation Stimulation of chronic inflammation Canceration of benign tumor Canceration of benign tumor Exposure to oncogens Exposure to oncogens

Pathology 1. SCC(35%-66%) , other: adenocarcinoma( only in paranasal sinuses), lymphoepithelial carcinoma, transitional epithelioma, BCC, sarcoma. 2. Carcinoma> Sarcoma( : 1). 3. Most of sarcoma is malignant lymphoma(>60%).

Treatment key point- first time treatment ① chemotherapy/ radiotherapy+ surgery ① chemotherapy/ radiotherapy+ surgery ② surgery+ chemotherapy/ radiotherapy ② surgery+ chemotherapy/ radiotherapy Combined modality therapy( based on surgery)

modus operandi : modus operandi : 1. lateral rhinotomy( Moure incision) 2. total maxillectomy( Weber-Fergusson incision) 3. “T” incision in nasal root( Presinger incision) 4. external frontal sinusotomy (Lynch incision) 5. sublabial approach ( Denker incision) 6. midfacial degloving 7. combined craniofacial approach

 Radiotherapy: 1. Simple radical radiation therapy— sarcoma, undifferentiated carcinoma 2. palliative radiation therapy—advanced stage 3. Preoperative radical radiation therapy-- 60Cobalt, linear accelerator, 4-6 weeks, 50-60Gy.  Chemotherapy:
