A new description of the topographic anatomy of the ear states the concept in which the ear is formed by the concha and the extra-concha. Applied to surgery, this concept has great medical value. This new description of the topographic anatomy of the ear is very interesting due to its applications to surgery.

A technique is described for reconstructing through-and-through defects of the ala of the nose, using a compound flap from the nasal tip and the opposite ala. It is illustrated with two cases.
A simple technique is described for reconstructing skin defects of up to half the upper or lower lip. Visible scarring is minimised by making incisions within the vermilion border.
In this paper the enormous possibilities of using the principle of blood flow reversal in new surgical techniques are contrasted with the very limited number of scientific papers referring to this principle. Four illustrative cases are described.
This paper describes a new technique for reconstructing the nasal ala or the tip of the nose. It is useful for defects that are too large for closure with composite grafts and gives a good aesthetic result as there are no visible scars. An understanding of the vascular anatomy of the alar-columellar flap is essential if it is to be used successfully.
In the years that have passed since my 1972 publication, the number of musculocutaneous flaps used can be counted by the many articles on musculocutaneous flaps that have been published in scientific journals. Surgery has become easier, quicker, with less hazard, suffering or pain for the patient, with more certain results and less worry for the surgeon. The incidence of flap necrosis has fallen remarkably. The huge effort to increase circulation in cutaneous flaps or tubes with multiple delay procedures which lasted weeks or even months, is now a thing of the past and should be relegated to the medical history books! I tell this story of the discovery of the method of the musculocutaneous flap because it is not well known. Those surgeons who are engaged in our specialty, especially if they are young, will enjoy reading it and find it of practical interest. When a physician has a patient who is very seriously ill and has no surgical means or medicament to cure him, he should always observe him. On many occasions he will find that his suffering is relieved.
In several countries in South America such as Colombia, Ecuador and Peru, many ceramics have been found which illustrate aspects of human anatomy, physiology and pathology that had been noticed and masterfully reproduced by the potter. A statuette in my private collection of pre-Colombian ceramics is approximately 2000 years old and belongs to the era of the Bahia culture. It depicts an important personage, possibly a political, social or religious leader, with a cleft lip and palate.
With the appearance of musculocutaneous flaps surgery became easier, quicker, and caused less morbidity and suffering for the patient. The operations of 2 patients who required the use of this new method are explained here. This report may prove interesting and useful to surgeons who work with musculocutaneous flaps.

The concha of the ear appears to be the best donor site for total nasal reconstruction, no matter what the cause of the loss of the nose. The advantages of the technique are as follows: (1) The skin is of the same color, texture, and thickness as that of a normal nose. (2) The osteocartilaginous framework is automatically provided by the conchal cartilage and a bony strut when required. (3) The lining is also an integral part of the flaps and does not require another source. (4) The nostrils are of good size and the patient breathes normally. (5) The ears from which the concha has been removed keep their normal shape, size, and appearance, and are only slightly flatter than normal. Replacement of the concha by a skin graft does not change its cosmetic appearance.
