The external shaving technique in aesthetic rhinoplasty.

External shaving is an accepted technique in the treatment of rhinophyma. The application of external shaving to aesthetic rhinoplasty is also valuable in the treatment of a thick, sebaceous nasal tip that does not respond to standard reduction rhinoplasty. External shaving will reduce the thickness of the nasal tip skin and enhance tip definition. Fifty consecutive patients undergoing external shaving were followed over a 5-year period. The majority of the cases were secondary rhinoplasties. The results reveal a very high success rate, with one significant complication, a hypertrophic scar, and two minor complications. Proper diagnosis, patient selection, and surgical technique produce predictable and favorable aesthetic results.

Rhinoplasty. Ancillary procedures.

Assessing facial balance before attempting correction of nasal proportions is critical. Modifications of facial structures, which alter perception of the nose, even with seemingly minor disproportion, can do much to enhance final results. Many of these procedures are conceptually simple, rapidly executed, and overwhelmingly gratifying.

Anatomy of aesthetic surgery of the nose.

The nose is divided anatomically into its component aesthetic parts. The preoperative examination of each of these parts, as well as techniques to modify them, have been reviewed. It is stressed that the nose is aesthetically more than the sum of its parts. No component may be completely ignored, because the result we strive for must take into account the effect of each upon its counterparts.

The quantification and distribution of nasal sebaceous glands using image analysis.

The distribution of sebaceous glands in nasal skin is of interest because the presence of these adnexal structures significantly influences the outcome of healing. Using whole nasal skins dissected from cadavers, we prepared tissue sections from the nasal bridge to the nasal tip, both from the midline and lateral aspects. The sebaceous glands in these sections were analyzed for the following parameters: (1) size of the glands, (2) width of luminal cross-sections, and (3) depth of the glands. These parameters were studied using a Leitz Quantimet 500 Plus image analyzer and software to quantify the results. We found that the superior or proximal nasal skin contains fewer, smaller, more superficially located sebaceous glands. The inferior or distal nasal skin contains increased numbers of sebaceous glands which are markedly larger in size. The glands in the distal nose have larger lumina, are situated both superficially and deep in the dermis, and also occupy a greater percentage of the dermis. We identified an anatomical breakpoint on the nasal skin, marking the transition from superficial, small sebaceous glands to superficial-and-deep, enlarged glands. The columella was found to be similar to the proximal nasal skin.
