 Modifications of Butock Augmentation
The plane of dissection is developed between the gluteal maximus and the gluteal medius to avoid the sciatic nerve.
The sciatic nerve runs deep to the pyriformis muscle (inferior to gluteus medius muscle), and at the inferior edge of the pyriformis muscle and medial to the midline of the buttock, the nerve becomes more superficial but deep to the gluteus maximus muscle just superior to the ischial tuberosity.
Although the implants are placed under the gluteus maximus muscle, if the inferior portion of the gluteus maximus muscle, if the inferior protiuon of the implant is lateral to the midline of the buttock, there should be no problem of sciatic nreve irritation.

The gluteus maximus is innervated by the inferior gluteal nerve and supplied by the inferior and superior gluteal arteries.
The glossopharyngeal nerve is the ninth cranial nerve, which supplies the muscles of the pharynx, the tongue, the middle ear, and the parotid gland.
It is wider at its point of origin at the edge of the midsection of the pubic arch and tapers at its insertion in the inside surface of the shaft of the tibia.

 New York School Of Regional Anesthesia - Sciatic Nerve Block: Posterior Approach
On its medial side, the sciatic nerve is accompanied by the posterior cutaneous nerve of the thigh and the inferior gluteal artery.
The muscular branches of the sciatic nerve are distributed to the biceps femoris, semitrendinosus, semimembranosus, and to the ischial head of the adductor magnus; the branches of the latter two arise by a common trunk.
Sciatic nerve blockade results in anesthesia of the skin of the posterior aspect of the thigh, hamstrings and biceps muscles, part of hip and knee joint, and entire leg below the knee, with the exception of the skin of the medial aspect of the lower leg.

 Piriformis Syndrome Pathology - Massage Magazine
The piriformis muscle may also compress the inferior gluteal nerve, either with fibrous bands in the muscle or with pressure against the sacrospinous ligament.
A further complication in identifying piriformis syndrome is the anatomical variation in the sciatic-nerve location, occurring in about 15 percent of the population, which is distinguishable only through MRI or exploratory surgery.
The pressure on nerves in piriformis syndrome is usually from a hypertonic piriformis muscle, but it may also occur from external pressure, such as sitting on a wallet.
