Aesthetic perspectives regarding physically and mentally challenged patients.

Cosmetic surgery was undertaken on a limited number of physically or mentally challenged patients. Motivation for surgery seemed to mimic those of average cosmetic surgery patients, although the request for surgery was more difficult for some patients in view of their physical or mental challenges. Patient and surgeon satisfaction was extremely high. In each case, expectations were realistic. Physical or mental variations should not cloud the indications for cosmetic surgery; on the contrary, it may be a wonderful way for the plastic surgeon to contribute to bettering the life of those less fortunate.

In search of the ideal nose.

The proportions of the so-called ideal nasal shape and the operations designed to achieve this have been the subject of innumerable papers. The vast majority of patients in the authors' practices desire a more refined version of the nose and do not want the so-called nosejob look with ideal proportions. A total of 2930 cosmetic rhinoplasties performed over the past 20 years, based on the philosophy of refining the more unrefined features of the nose according to the patients' wishes, have been reviewed, and almost all of these patients were satisfied with the long-term shape of their nose, even though in many cases these noses would be considered less than ideal by some of the newer criteria.

Botulinum A chemodenervation: a new modality in cerebral palsied hands.

Botulinum A chemodenervation of the Adductor Pollicis muscle for the treatment of the thumb-in-palm deformity in cerebral palsied hands is presented as a new therapeutic option. Early results of a clinical trial in five hemiparetic Cerebral Palsied (C.P.) children are assessed using a prospective nontrialist-biased study design based on an independent panel assessment of pre- and post-intervention photographic and videotaped records of hand function and appearance, in combination with grip dynamometry and goniometry. All cases are shown to improve in terms of both function and appearance with results approaching statistical significance (p = 0.06) when assessed by the Wilcoxon's matched-pairs signed rank test, despite the small study group. The modality is shown to be simple, safe and effective over the period reported (229 days). The benefit is sustained beyond the period of muscle paresis and ongoing long term follow-up will document the need for, and timing of, reinjection.

Degloving injuries and flap viability assessment.

Degloving injuries are associated with major morbidity. The management of these injuries is still not resolved. The method of management used by the authors involves the harvesting of split skin from the surface of the flap and assessment of flap viability based on surface dermal capillary bleeding. The skin grafts are then used to cover denuded areas. This technique has proved to be effective, time-saving and morbidity-reducing in the cases reviewed here and in recent publications. The issue addressed in this trial was the effect of partial de-epithelialisation on the survival length of a flap. Two groups of dorsal rat flaps were compared. In one group, the flaps were raised and restitched after a period of time and in the second group, the surfaces of identical flaps were partially de-epithelialised and then restitched. The survival length of these flaps was compared, as well as the metabolic responses to surgery in the two groups. No statistically significant differences were found in these 2 groups. It was concluded that partial de-epithelialisation did not have a detrimental effect on duration of flap length survival, thus encouraging the continued use of the clinical technique described above in the handling of degloving injuries.

Use of costal cartilage cantilever grafts in negroid rhinoplasties.

Dorsal augmentation and nasal tip refinement are important objectives in Negroid rhinoplasty. Use of a costal cartilage cantilever graft will achieve these objectives. We report on our experience in 19 patients. The technique offers an excellent solution to supplying the large amount of material often required to adequately augment the dorsum in these patients. The graft is also versatile enough to allow nasal tip refinement. There are additional aesthetic benefits as the cantilever causes a lengthening in the nasal columella, a reduction in the flare of the nostrils, and increases the columellar-labial angle. The procedure is relatively simple to perform. The problem of warping is minimized by symmetrical carving and the use of large grafts with a substantial cross-section.

A modified frontalis sling in the treatment of combined blepharoptosis and facial nerve paresis.

A surgical method is proposed to treat patients with combined severe blepharoptosis and peripheral facial nerve paresis. The operation involves construction of a sling from the contralateral active frontalis muscle to the affected eyelid tarsal plate. The method has been applied in one patient, with satisfactory results. Re-education of the patient was relatively easy to achieve.

Reconstruction of the alar groove.

The obliteration of a well-defined alar groove is common after nasal alar reconstruction. A method is described that can be used at the time of reconstruction to ensure the continued definition of the groove or to restore it in cases where it has been obliterated. The technique is based on the natural tendency of the skin to tube itself. Cheek skin is advanced beneath the posterior free edge of the reconstructed ala so that this edge now comes into contact with an epidermal surface. As this edge now tends to tube itself, a natural alar groove is produced. This method has been used successfully in six cases.

Tumours of accessory parotid glands. Case reports.

Tumours arising in accessory parotid glands are a distinct entity and a pitfall for the unwary . The diagnosis is made on the basis of clinical examination and a high index of suspicion is essential. Treatment is by wide exposure and careful dissection because of the relationship of the accessory parotid gland to the facial nerve and parotid duct. Four cases are described.

The free latissimus dorsi myocutaneous flap.

The anatomy and development of the free latissimus dorsi myocutaneous flap is described and 3 cases in which it was used to repair large tissue defects are presented. Its advantages and disadvantages compared with conventional methods of soft-tissue repair are discussed.

Metacarpal reconstruction in compound contaminated injuries of the hand.

The use of an external distraction fixation apparatus in severe compound contaminated injuries of the hand with avulsed segments of metacarpals is described. The method has the advantages of stabilizing bony fragments, maintaining hand length and allowing early access for dressing until reconstruction with a bone graft can be undertaken.
