Very least of maxillectomy with the fitting of an obturator, and before

embarking on such major treatment, it is important to select only patients who

are likely to have a reasonable chance of survival. To this end, the elderly,

those who are infirm from other disease, those with trismus, cervical glandular

enlargement, evidence of erosion of the base of the skull, or evidence of

distant metastases should not be submitted to this major treatment regime.

Radiation consists of a full course of 6000 rads delivered by a linear

accelerator. Six weeks later surgery takes place. All patients should be warned

pre-operatively of the possibility that their eye may have to be sacrificed to

obtain clearance of the tumour. The extent of surgery depends upon the position

and the size of the growth. In localized antero-inferior neoplasms, removal of

the maxilla with preservation of the orbital floor is possible, the resulting

palatal defect being filled with an obturator attached to the upper dentures.

With more superior growths the whole maxilla is removed, as are any involved

ethmoidal cells. The eye may require to be sacrificed if the orbit is involved.

If the soft tissues of the cheek are infiltrated by tumour, this area will have

to be included in the resection.

Palliative treatment for those unsuitable for the above regime, or for those

suffering from recurrent tumour, is limited to general nursing care,

psychological support and adequate relief of pain. There is no evidence that

chemotherapy plays a useful role in the control of nasal and sinus tumours of

epithelial origin, although it is very useful in the control of lymphomatous

tumours.

Prognosis. Various classifications have been used over the years to gauge

prognosis. In general, a better prognosis is likely if the tumour arises from

the anterior and inferior part of the maxillary sinus, and the outlook is poorer

the more superior the origin of the growth.

The outlook is grave in children and young adults who tend to have very

malignant sarcomas. The prognosis is better for the common squamous carcinomas

where a 5-year survival of 30% is expected. Tumours of salivary gland origin,

like adenoid cystic carcinoma, have a better short-term prognosis, but many of

these patients die with recurrent tumours many years later.

TUMOURS OF THE PHARYNX

Benign tumours of the nasopharynx

Benign tumors of the nasopharynx are rare. The most frequent is the

nasopharyngeal angiofibroma. This occurs exclusively in the male, beginning

about the age of 20-25, but this is not true of all cases.

Symptoms. These include increasing nasal obstruction, purulent rhinosinusitis

due to obstruction of the nasopharynx, severe spontaneous bleeding from the nose

or pharynx, rhinolalia clausa, headaches, obstruction of the ostium of the

eustachian tube causing conductive deafness, middle ear catarrh, and purulent

otitis media. Posterior rhinoscopy shows occlusion of the nasopharynx by a

smooth greyish-red tumor which may be lobulated and have offshoots penetrating

the choana or Rosenmuller fossa. The surface of the tumor often shows pronounced
