Premaxillary augmentation: adjunct to rhinoplasty.

Recession of the premaxillary area is a relatively common deformity. Typically, it presents as a mild weakness of the central maxilla, but in certain instances, such as in the Black and Asian communities, it may be moderate to severe. This condition can be compounded by a narrow nasolabial angle, recessed alar bases, and sunken cheeks. To resolve this deficiency, a new design for premaxillary augmentation is suggested. A bat-shaped premaxillary implant is used for correction. The implant is introduced by means of an intranasal or intraoral approach, while the patient is under either local or general anesthesia. Thirty-three patients have been managed for premaxillary recession and have been corrected by premaxillary augmentation. Satisfactory cosmetic results have been achieved, with only a few minor complications.

Unilateral osteotomies for external bony deviation of the nose.

Most crooked noses, at the end of a regular rhinoplasty, seem well positioned in the midline. However, several months later, the nasal pyramid may begin its lateral migration and the original deviation, to the chagrin of the surgeon, is partially reproduced. An approach to the externally deviated bony pyramid is reemphasized, involving the performance of one or more osteotomies on only one side of the nose.During the course of a regular rhinoplasty, the bilateral lateral osteotomies displace the lateral nasal walls medially. However, if only a unilateral osteotomy is performed, the nasal dorsum will seem to deviate toward the opposite side. This paper discusses in further detail how to use unilateral osteotomies in the rhinoplasty of an externally deviated nose. Although the unilateral osteotomy technique is not a new concept, it did not receive so far the interest it deserves among surgeons. The unilateral osteotomy technique is an adjunctive solution to a complex problem.

Collapsed nasal-valve widening by composite grafting to the nasal floor.

OBJECTIVE: The primary aim of this article is to provide surgeons with a "how to do it" approach to surgically increase the widest diameter of the nasal valve. METHOD: An approach utilizing a composite graft from the aural concha to the nasal floor is described, with a brief report of the postoperative results in 13 cases. RESULTS: An objective, measurable improvement in nasal-valve aperture was demonstrated in 77% of operated cases, with 77% of patients indicating a good to excellent rating in satisfaction with the procedure. CONCLUSION: With minimal scarring and no excisions of supporting structures involved, this method has proved to be effective in the repair of nasal-valve narrowing.

Finite element analysis of airflow in the nasal valve.

We digitized the outline of the nasal cavity from images obtained after applying contrast material to the nose. A computer-aided simulation of flow was undertaken in the sagittal plane in the anterior nasal cavity. Previous work on the nasal valve was reviewed. Our results showed that the nasal valve is an oblique structure bounded laterally by the caudal end of the upper lateral cartilage, medially by the septum, and ventrally by the inferior rim of the piriform aperture. We found that this rim, projecting from the floor of the nose, produces an uneven distribution of airflow through the valve with most of the flow occurring in the ventral segment. Removal of this rim should result in a more even distribution of flow across the valve.

Mersilene tip implants in rhinoplasty: a review of 98 cases.

Reshaping the nasal tip is the most difficult part of a rhinoplasty, particularly in certain types of nasal tip deformities, such as the recessed tip, the thick-skin tip, the boxy tip, the asymmetrical tip, the thin-skin tip, the bifid tip, the turned-up tip, and the turned-down tip. A new approach is introduced regarding the use of Mersilene tip implants. Guidelines for preoperative evaluation and surgical technique are outlined. The so-called "PEPSI" rule (pocket, experience, positioning, shape and size, and incision) is emphasized. The advantages and disadvantages of the Mersilene tip implant are discussed. The Mersilene implant was used in the tip region in a total of 98 patients, and the results are satisfactory.

Anterior nasal collapse: flaccid or rigid? An approach to clinical diagnosis.

Nasal obstruction secondary to anterior nasal collapse is a most frustrating and confusing problem with no clear guidelines for diagnosis. A clinical classification of the collapse of the anterior nasal cavity is suggested. Surgical management is only briefly discussed. The aim of this paper is to simplify the clinical diagnosis and classification of this complex entity.

Supramid tip implants in rhinoplasty. Review of 98 cases.

The nasal tip procedure is the most sophisticated aspect of a rhinoplasty, particularly in certain known problem types of nasal tips. A new approach, using Supramid tip implants, is introduced. Precise guidelines for the preoperative planning and operative techniques are developed, and the so-called pocket, experience, positioning, shape and size, and incision (PEPSI) rule is outlined. A comparative discussion of the advantages and disadvantages of the Supramid implant vs cartilage grafts and/or repositioning of alar cartilages is presented. The Supramid implant was used in the tip area for nasal tip alteration in a total of 98 cases. Patients were monitored for a period of six months to four years. The results were satisfactory.

Anterior turbinectomy. A new surgical approach to turbinate hypertrophy: a review of 220 cases.

Surgical correction of mechanical nasal airway obstruction is commonly treated by septoplasty. The nasal airflow, however, is often inadequate postoperatively. The inferior turbinates are responsible for nasal obstruction more often than is realized. Recent studies have confirmed that the main site of respiratory resistance is located at the level of the anterior ends of the inferior turbinates. A new turbinectomy approach in which the anterior end of the inferior turbinate is resected with a specially modified forceps is described. A large series of patients, along with their follow-up data, are described. The advantages of the anterior turbinectomy are discussed.

Revision rhinoplasty. A decision dilemma.

Although most of the previous literature on revision rhinoplasty discusses a certain nasal deformity with its specific management, patients seen for revisional rhinoplasty are usually seen with a combination of different problems that confuse the surgeon. The aim of this article is to offer a simplified and systematic approach to revision rhinoplasty. Examples of preoperative cases, their step-by-step analysis, and postoperative results are given.

Correction of thin lips: "lip lift".

Thin, atrophied lips are a stigma of old age. This paper discusses the so-called lip lift, an operation that consists of lifting, everting, and increasing the bulk of the upper and lower lips by means of a simple but meticulous procedure along the vermilion border. An introductory study on lip aesthetics is presented. Preoperative planning is greatly emphasized. This technique has been used by the author in 32 cases as an adjunct to facial lifts or as a separate procedure. The patients were followed for up to 3 years. The results were quite satisfactory.

Male and female face-lift incisions.

The factors and differences in incisions for face-lifting in women and men are presented and discussed in detail. The recommended approaches hide scars effectively, allow the hair growing in front of the ear to be left in its original location, and prevent future hair growth from being too close to the ear, which would make shaving or washing difficult in men.

The "light reflex" tip-plasty-a new theory in tip esthetics and tip correction.

What makes a tip well defined, appealing, and natural looking is not only the gross shape, but also a certain pattern of linear light reflexes which correspond to the undulation of the surface. A study was carried out on a dozen individuals thought to have attractive nasal tips. Photographic and drawing techniques were used to analyze the linear pattern of the "light reflex" on the tip, and to determine the pattern of the surface configuration of an attractive tip. Next, the tip reduction in rhinoplasty was planned in such a way as to ensure that the cut edges of the remaining alar cartilage will reflect the light in the desired pattern, hence giving the visual illusion of a natural tip configuration. This new technique was tried on more than 50 patients over a period of three years. The long term follow-up was very satisfactory.

The absorbable nasal pack.

Fifty-six patients undergoing different types of nasal surgery were packed at the end of their procedures with an absorbable type of packing (oxicel, surgicel) only. Details of the packing technique in vertical layers are presented. Patients were followed up closely for a variable length of time. This new technique of only using absorbable packing material has proven to be extremely comfortable for the patients and a most efficient hemostatic agent (not a single case of post-op bleeding, even with turbinectomy procedures). Contrary to the case with the classical vaseline pack, the patients were not miserable from the pressure of the pack and were not apprehensive waiting for its removal. The absorbable pack also saves for the surgeon the time and effort spent in the unpleasant job of taking out a nasal pack.

Blepharoplasty: when to combine it with brow, temple, or coronal lift.

Some patients coming for esthetic blepharoplasty should have one of three supplemental procedures performed to elevate or change the position of the eyebrows. The most precise eyebrow alterations are effected with brow lifting procedures, but these may produce adverse scarring. The temple lift may be employed to draw the lateral part of the eyebrow upward and laterally. Drooping of the central part of the eyebrow requires a frontal or coronal lift or an eyebrow lift. Additional guides to the selection and combination of the procedures are provided.
