Psychosocial outcome of patients after ear reconstruction: a retrospective study of 62 patients.

This was a retrospective study examining the psychosocial morbidity of patients before and after ear reconstruction. Semistructured questionnaires were sent to 90 patents with significant congenital or acquired auricular deformity 2.2 years (range 3 months to 5 years) following autogenous or osteointegrated reconstruction. Sixty-two patients (69%) responded. Twenty-two of the patients below 12 years, who had undergone reconstructive surgery, also completed the Childhood Experience Questionnaire. These were compared with a cohort of 362 normal patients. There was significant psychosocial morbidity in both children and adults with auricular deformity. Seventy-one percent of patients reported reduced self-confidence that affected both social life and leisure activity. Teasing was a prominent symptom in both children (88%) and adults (85%) but was a motivational factor for surgery in children only. Dissatisfaction with the appearance (73.1%), on the other hand, was the main reason for treatment in adults. Following ear reconstruction, 74% of adults and 91% of children reported an improvement in self-confidence resulting in enhanced social life and leisure activities in both adults and children. There was no difference between osteointegrated and autogenous reconstruction. Sixty percent of patients reported their result as excellent. The patients scored their result better than the surgeon. We conclude that auricular reconstruction has significant psychosocial benefit in the majority of children and adults despite donor-site morbidity and a range of technical result.

A splint for correction of congenital ear deformities

Fourteen non-hypoplastic congenitally deformed ears were treated with a simple splint with satisfactory results in all but one. These deformities can be treated non-surgically in the early neonatal period, effectively, without anaesthetic, and with minimal cost. We confirm other reports that better results are obtained and a shorter duration of splintage is needed if treatment is started early in the neonatal period. Our neonatal paediatric colleagues and midwives should be encouraged to manage these deformities in this way, and the need for surgical correction may be largely avoided in the future.

Donor-Site Morbidity after Autologous Costal Cartilage Harvest in Ear Reconstruction and Approaches to Reducing Donor-Site Contour Deformity.

Background: Harvesting of rib as a source of cartilage can result in significant donor-site morbidity. In experienced hands, excellent results from using autologous rib cartilage are achievable for ear reconstruction, rhinoplasty, and otolaryngology. The authors report the morbidity associated with the harvest of costal cartilage in 42 patients who underwent ear reconstruction. Methods: The notes were examined retrospectively and further data were collected with a questionnaire. Patients noted their experience of pain, clicking, and satisfaction with the donor site. Fifteen patients underwent additional clinical assessments of their donor scar and contour deformity using a standardized scale. Five donor sites were reconstructed with spare cartilage left over from carving the ear framework. Results: The results showed that pain and clicking of the chest wall represented the commonest complaints. These peaked in the first week after surgery and diminished slowly over 3 months. The donor-site scar and deformity were acceptable to most patients. There was an improvement in the contour deformity of the chest wall harvest site in the five patients who underwent reconstruction of their donor site. Conclusions: To improve the outcome for patients undergoing cartilage harvest, efforts must be made to further reduce pain and donor-site morbidity. Reconstruction of the donor site with spare cartilage should be attempted where possible to improve the contour defect of the donor site. Refinements in the methods of cartilage harvest or donor-site reconstruction may achieve this in the future.

5-year series of constricted (lop and cup) ear corrections: development of the mastoid hitch as an adjunctive technique.

&NA; Despite the multitude of corrective procedures described, adequate surgical correction of the congenital constricted ear remains a challenge. The maintenance of the shape and elevation of the reconstructed upper neohelix poses a particular problem. In the present series, experiences with lop ear correction utilizing standard techniques and the use of the mastoid hitch as a useful adjunct to these procedures are described. A total of 19 ears were reconstructed. There were three type 1, eight type 2a, seven type 2b, and one type 3 deformities (Tanzer classification). A graded sequence of procedures was adopted. Mild deformities were corrected by cartilage scoring techniques; a V‐Y advancement of the helical root was added for moderate deformities. Cartilage expansion by a banner flap was required for more severe deformities. A mastoid hitch, whereby the refashioned upper neohelix is sutured to the mastoid fascia, should be used as an adjunct to these procedures to maintain helical elevation and prevent recurrence. Severe type 3 deformities may require autologous auricular reconstruction. Mean follow‐up time was 1 year. There were six excellent, seven good, four fair, and two poor results. Two patients who had not had mastoid hitch procedures developed a recurrence of the lop deformity. Adequate surgical correction of constricted ear deformities requires a variety of surgical techniques. The mastoid hitch being used for constricted ear correction has not been described elsewhere. The mastoid hitch is a useful adjunctive procedure that may be used effectively in combination with other procedures. (Plast. Reconstr. Surg. 102: 2325, 1998.)

ruby Laser-assisted Hair Removal Success in Relation to Anatomic Factors and Melanin Content of Hair Follicles

Ruby laser-assisted hair removal is thought to work via selective photothermolysis, which relies on light reaching the deeper layers of skin, and the absorption of light by the target chromophore, melanin. It is therefore possible that efficacy of treatment is affected by anatomic factors that determine the amount of light reaching the hair bulbs (i.e., skin color, depth of intracutaneous hair, epidermal thickness and dermal density) and the melanin content of hair. To examine this hypothesis, a prospective study was performed. Forty-eight volunteers were treated with the Chromos 694 Depilation Ruby Laser at a single standard fluence of 11 J/cm2. Treatment efficacy was determined by measuring hair density at 3 and 7 months after treatment. Epidermal depth and dermal density were measured from 2-mm biopsies taken before treatment, and the intracutaneous hair length was determined from plucked hair. Skin color was assessed using a spectrophotometer, and melanin content of dissolved hair was assessed using spectrophotometry. Efficacy of treatment for each patient was compared with the patients age, intracutaneous hair length, epidermal depth, dermal density, skin color, and total melanin content and relative eumelanin content of hair. No correlation was found between the efficacy of treatment and age and the various anatomic factors. Patients with higher eumelanin content in their hair had better long-term results (Spearman rank test, p = 0.00219). The results suggested that the efficacy of treatment did not depend solely on the amount of laser light penetrating the skin but correlated well with the eumelanin content of hair. The clinical implication of this finding is discussed.

When do ears become prominent

Non-hypoplastic congenital ear deformities are amenable to non-surgical treatment with splinting in the neonatal period. It is therefore important to determine when the deformity occurs. 100 postal questionnaires were sent to parents to study, retrospectively, the evolution of the prominent ear deformity in their children. 79 questionnaires were returned. As remembered by parents, the deformity was first noted at birth in 48 (61%) children, in 68 (86%) by 6 months and in all cases by 5 years. Therefore a large number of patients with prominent ears could be treated effectively, non surgically, early in life, without anaesthetic and with minimal cost.

Ruby laser irradiation (694 nm) of human skin biopsies: assessment by electron spin resonance spectroscopy of free radical production and oxidative stress during laser depilation.

Abstract Human skin biopsies (hair‐bearing scalp skin and non‐hair‐bearing breast skin) were treated with t‐butylhydro‐peroxide, irradiated with UV light (UVR) or irradiated with 694 nm ruby laser red light. Free‐radical production and oxidative stress were assessed with electron spin resonance spectroscopy (ESR) using the ascorbate radical as a marker. In comparison with both UVR and t‐butyl‐hydroperoxide (which readily induce the ascorbate radical in hair‐bearing and hairless skin), 694 nm red light does not result in the formation of the ascorbate radical in detectable concentrations. Spin‐trapping experiments with the spin trap 5,5‐dimethyl‐l‐pyrroline N‐oxide (DMPO) showed that while free radicals could be detected after treatment of skin with t‐butylhydroperoxide, radicals could not be trapped after laser treatment. Treatment of lasered skin (containing DMPO) with t‐bu‐tylhydroperoxide produced radical adducts as well as the ascorbate radical, demonstrating that the laser neither depletes endogenous ascorbate nor the preadministered spin trap. It is concluded that 694 nm red light does not induce oxidative stress in human skin in levels comparable either to t‐butyl hydroperoxide or UV light.

The effect of ruby laser light on ex vivo hair follicles: clinical implications.

Several clinical studies on the efficacy of ruby laser-assisted hair removal have reported that regrowth of hair after treatment is common. One of the reasons for the regrowth of hair is the incomplete destruction of germinative hair cells due to the insufficient penetration of the ruby laser in the skin. It was the aim of this study to estimate the extent of damage to the hair follicles after one ruby laser treatment and to determine whether the ruby laser destroyed the bulbs and the bulge regions of hair follicles. The extent of laser damage in hair shafts was determined by serial examination of six specimens of ex vivo scalp skin lasered with the Chromos 694 Depilation Ruby Laser at 14 J per square centimeter and 20 J per square centimeter. Another nine specimens of ex vivo scalp skin were similarly lasered, and monoclonal antibody LP2K was used to identify the bulge regions of the hair follicles using the immunoperoxidase technique. Damage to the bulge region was assessed from consecutive specimens, which were stained with hematoxylin-eosin stain. The mean depth of laser damage sustained by hair follicles was 1.34 mm (14 J per square centimeter) and 1.49 mm (20 J per square centimeter) underneath the skin surface. Most of the laser damage involved the bulge regions but fell short of the hair bulbs. The laser damage did not seem to extend far enough down the hair shafts to result in permanent hair destruction. The clinical implications of this finding are discussed.

Tissue expansion as an adjunct to reconstruction of congenital and acquired auricular deformities

The role of tissue expansion in ear reconstruction has not been clearly defined. Tissue expansion was used to reconstruct 16 ears for posttraumatic, burn and congenital defects. Previous surgery or scarring in the region of the reconstruction was not regarded as an absolute contraindication. The overall complication rate was 31.2%. According to the senior authors grading system, the contours were excellent in 4 ears, good in 9 ears and fair in 3 ears.

Post traumatic ear reconstruction

This is a review of 249 patients who have suffered ear trauma and who have presented for reconstruction over the last eighteen years. All were born with normal ears and had lost one or both ears or a major segment of the ear. Congenital ear problems including microtia are not included.
