ORJI, G.I; OBASOHAN, M; ANYANWU, C.C
|
|
HISTORY |
S.R, Hosp no.6166, 36years, male.
Presented on 30.5.05 with a 4-yr history of a non-painful right
jaw tumor, steadily increasing in size. There was no weight
loss, and no cough. |
|
PHYSICAL
FINDINGS |
He
looked healthy and was neither pale nor jaundiced. There was
a 10 X 8 cm swelling visibly situated on the right parotid region,
and shaped exactly like a parotid gland tumor. There was no
regional lymph node enlargement, and no facial palsy. |
 |
|
INVESTIGATIONS |
CXRay
and x-ray of the neck were normal. FBC was normal, ESR 5mm/hr,
HIV I & II – negative, HbsAg – negative. |
|
SPECIFIC
THERAPY |
A
diagnosis of a right parotid pleomorphic adenoma was made. However
at surgery, under intubated general anesthesia, an edematous
right parotid gland was found overlying a deep-seated mass 10
X 8 cm, smooth surfaced and well encapsulated, and attached
firmly to the anterior part of the cartilage of the middle ear. |
 |
|
AFTER-CARE |
Post-op
care was uneventful, except that the parotid tissue edema persisted
for nearly 6 months, simulating the pre-operative condition
in shape and size. Histological examination showed angiofibroma,
and no parotid tissue was seen. Access to the tumor was achieved
by a transverse incision on the mid-parotid, avoiding the branches
of the facial nerve. |
 |
| COMMENT |
The
surgery commenced as with that for the excision of a superficial
parotid tumor. The facial nerve lying beside the mastoid process
however did not enter the tumor, which had a plane of cleavage
separating it from the deep part of the parotid gland. |
