The parotid fascia is not the superficial layer of the investing layer of the cervical fascia. The dissection of 21 cadavers, the histological studies and the compared anatomy of 3 apes show that the parotid gland lies between the platysma muscle on the lateral side and the superficial layer of the cervical fascia on the medial side. The upper part of the platysma, large muscle in apes, has regressed as a fibrosis layer in man.
Dropping of the tip of the nose after surgery is mainly the result of either too extensive resection of the alae or excessive resection of the septum. In the first case, the resulting round or hooked nose can be corrected by an auto or homologous cartilage graft. In the second case, following surgery to obtain functional improvement, the presence of an osteocartilaginous hump can be exploited to support the tip, or a conventional flap can be employed, composed of alar chondromucosal tissue. These remarks are but one particular feature of secondary surgery to the nose, a delicate surgery in full expansion.
