Methods and systems configured to treat a patient's glottic insufficiency are disclosed. An implant system may include a first implant positioned in the patient's paraglottic space. The first implant is adjustable in volume by changing amount of filler in the implant. The implant system may include a fixation device fixated on or through a cartilage opening in the patient's thyroid cartilage. The fixation device may contain a first channel. The implant system may include a first tube having a first end coupled with the first implant. The first tube passes through the first channel of the fixation device to deliver the filler to the implant. The implant system may further contain a port coupled with a second end of the first tube to regulate the amount of filler in the implant.
