Will upper blepharoplasty --> ptosis correction of one eye?

Not exactly. Ptosis of the eyelid is corrected, in most cases, by advancing the levator muscle, which raises the eyelid. It is done through the same type of incision as a blepharoplasty and the two procedures are often combined in older people. In some cases, ptosis is corrected by an incision on the inside of the eyelid, which would not be combined with blepharoplasty.
Ptosis etc. Ptosis is a droopy upper eyelid this is treated with ptosis surgery to elevate the upper lid level. Blepharoplasty is surgery to remove excess skin around the eyes. This can be performed on upper or lower lids or both at the same time. Extra upper lid skin that folds over the eyelid and can weigh it down & possibly block the upper visual field is called dermatochalsis.
No. Ptosis repair is a separate procedure from an upper eyelid lift. The two can be performed at the same time. However, a standard blepharoplasty will not remedy ptosis. Seek an experienced oculoplastic or facial plastic surgeon for consultation. If someone says a bleph will fix an eyelid droop ... Keep looking.
A particular type. ...Called levator advancement would do that. See an abps plastic surgeon or oculoplastic surgeon.
No, but... Upper blepharoplasty is done to remove excess skin and fat. True ptosis is caused by stretching of the muscle-tendon unit that lifts the upper lid. If there is a great excess of upper lid skin, one may get the false impression of ptosis, but true ptosis means that the margin of the upper lid sits too low on the eyeball. They can be done together but are two separate procedures.
Depends. If the ptosis is due to the excess skin of the upper lids the blepharoplasty can help to correct the drooping of the eyelid. If the ptosis is due to muscle problem then that has to be addressed by fixing the muscle with or without the blepharoplasty.
