Dear all,
I came up with a sentence whose interpretation I'm not confident in while I was reading an article on tooth decay. Any comments on my reading will be appreciated. Here is the sentece:

"A severely decayed tooth can become abscessed, resulting in purulent drainage directly into the oral cavity or to the development of facial cellulitis."

I wonder what the second part of this sentence starting with the phrase "resulting in" really mean. My first interpretation is:

"abscess caused by decayed tooth can result in one's PURULENT DRAINAGE into the oral cavity or can also result in PURULENT DRAINAGE to the development of facial cellulitis." (Let me call this interpretation "(1)").

However, "PURULENT DRAINAGE to the development of facial celullitis" sounds a little odd to me both in grammatical and intepretitative sense, though I am not a specialist in this field.

GIven this consideration, the alternative interpretation like the one in the below may be better:

"Abscess caused by decayed tooth can result in one's PURULENT DRAINAGE into the oral cavity or can also result in the DEVELOPMENT of facial cellulitis." (Let me call this interpretation "(2)".)

* * *

Thus, my questions are:
(a) Which interpretation, (1) or (2), is actually correct, or looks more plausible?
(b) If (2) is correct or better, is the original preposition "to" before the phrase "the development of facial cellulitis" used in a grammatically correct way?

Thank you very much for your kind attention.

All the best,
Tara
PS: This is Tara (the one who have posted this) again. I used a wrong phrase "came up with" in my question. I should have used "came across" there. Thanks.
First, let me say, "Eeeww."

The writer made a mistake. He meant "resulting in purulent drainage directly into the oral cavity or leading to the development of facial cellulitis."

Dear enoon,
Thanks a lot!!
Tara
it was and good try i will ask some one eles and come back.
A little late, but this is my take on it:

"A severely decayed tooth can become abscessed, resulting in purulent drainage directly into the oral cavity or to the development of facial cellulitis."

A severely decayed tooth can become abscessed, resulting in:
a) purulent drainage [directly] into the oral cavity or
b) [to] the development of facial cellulitis

As you can see, the words "directly" and "to" are redundant.
