NEOPLASMS OF THE NASAL PASSAGES 29 



removal fails it is best to trephine the superior wall of the 

 nasal passages and extirpate the tumor through the opening. 

 After-treatment consists of warm antiseptic solutions injected 

 daily up the passages. 



Malignant Tumors.— Occasionally in the nasal passages 

 are found epitheliomas, osteosarcomas, and sarcomas which 

 are usually secondary to primary growths having their origin 

 in the buccal mucosa, maxillary bones or lips (epitheliomas) . 



Symptoms.— Malignant growths give rise to distortions of 

 the nasal bones, lips and often result in necrosis of the parts 

 involved. The nasal discharge will contain necrotic material 

 and blood and has a very offensive odor. 



Diagnosis.— To make an accurate diagnosis some of the 

 tumors should be obtained and examined microscopically. 



Prognosis.— The prognosis is very unfavorable. 



Treatment.— Owing to the location of the tumors, their 

 malignant character and the tissues involved, treatment is 

 not to be attempted.
