Aesthetic Improvements of Skin Grafts in Nasal Tip Reconstruction.
Summary of "Aesthetic Improvements of Skin Grafts in Nasal Tip Reconstruction."
Defect closure on the nasal tip subunit still remains challenging. Full-thickness skin transplantation still is used despite its poor outcome in terms of the nasal tip contour caused by lack of dermal tissue. To avoid subsidence deformities associated with nasal tip reconstruction with skin transplants, this study analyzed methods using combined epidermal and dermal replacement. For 30 consecutive patients with a nasal tip defect, a retrospective comparison was made between conventional full-thickness skin transplantation, retroauricular perichondrodermal composite grafts, and skin transplantation supplemented with the collagen-elastin matrix, Matriderm, used as a dermal substitute (n = 10 per study group).The postoperative results were evaluated in a randomized and blind manner by external facial surgeons using the Manchester Scar Scale. The findings showed a marked improvement in nasal tip contour with combined epidermal/dermal replacement without any deterioration in other graft qualities, justifying the additional effort involved in this procedure. Two patients developed fistulae after Matriderm-aided skin transplantation. Therefore, the authors do not consider this a suitable method for nasal tip reconstruction.

Medical and Biotech [MESH] Definitions
Nasal Lavage Fluid
Fluid obtained by irrigation or washout of the nasal cavity and NASAL MUCOSA. The resulting fluid is used in cytologic and immunologic assays of the nasal mucosa such as with the NASAL PROVOCATION TEST in the diagnosis of nasal hypersensitivity.
The proximal portion of the respiratory passages on either side of the NASAL SEPTUM. Nasal cavities, extending from the nares to the NASOPHARYNX, are lined with ciliated NASAL MUCOSA.
Nasal Provocation Tests
Application of allergens to the nasal mucosa. Interpretation includes observation of nasal symptoms, rhinoscopy, and rhinomanometry. Nasal provocation tests are used in the diagnosis of nasal hypersensitivity, including RHINITIS, ALLERGIC, SEASONAL.
Diagnostic measurement of the nose and its cavity through acoustic reflections. Used to measure nasal anatomical landmarks, nasal septal deviation, and nasal airway changes in response to allergen provocation tests (NASAL PROVOCATION TESTS).
The partition separating the two NASAL CAVITIES in the midplane. It is formed by the SEPTAL NASAL CARTILAGE, parts of skull bones (ETHMOID BONE; VOMER), and membranous parts.
BACKGROUND: Thick nasal skin presents a challenge in rhinoplasty. Conventional spreader grafts in patients with thick nasal skin may result in an undesirable widening of the lower half of the nose whe...

BACKGROUND: Diced-cartilage grafts have been used for dorsal nasal augmentation for several years with good results. However, compounds such as Surgicel and temporalis fascia used as a wrap have inher...
Abstract A 77-year-old man was referred for treatment of a biopsy-proven multi recurrence basal cell carcinoma (BCC) on the dorsum of the nose. The lesion was removed and the resulting surgical defect...
BACKGROUND: Currently, acellular dermal substitutes used for skin reconstruction are usually covered with split-thickness skin grafts. The goal of this study was to develop an animal model in which su...
The purpose of this study is to determine if using a DERMAL LAYER under skin grafts: 1. will reduce scar formation of skin grafts 2. will reduce burn wound contractures 3. w...
This is a non-drug, biomarker study to assess the utility of the model of repeated nasal allergen challenges in subjects with atopic rhinitis as a method of inducing an increased response...
