Reconstruction of Nasal Defects With Dermal Skin Substitutes-A Retrospective Study of 36 Defects

[Analysis of the postoperative outcome of 81 cases of nasal reconstruction with direct closure]

BACKGROUND

Direct wound closure (side-to-side closure) for closing nasal defects, is controversially discussed. Yet, data supporting one or the other are lacking.

MATERIAL AND METHOD

An explorative, partly retrospective, partly prospective observational study including 81 patients was carried out for assessment of the operative results of after direct wound closure stretching rhinoplasty. The occurrence of complications, the esthetic result and influencing factors were examined. To assess the esthetic result the patient and observer scar assessment scale (POSAS) scores of patients and observers were determined. In both scores seven values were determined (1 point normal skin, 10 points worst imaginable scar). The individual values were added to give a total value (minimum 7-maximum 70).

RESULTS

After direct wound closure stretching rhinoplasty, 12 out of 81 patients (15 %) developed complications, in 5 cases suture dehiscence, in 5 cases cyst formation, in 4 cases a wound infection and 2 patients developed cyst formation and a wound infection. All suture dehiscences occurred on the lower third of the nose. Most of the patients were satisfied and assessed the scar with an average total value of 13.4 ± 7.07 (minimum 7, maximum 70, n = 42). In the individual assessments pain (1.14 ± 0.57; minimum 1, maximum 10) was rated best and scar color (2.50 ± 1.76; minimum 1, maximum 10) was rated worst. The total assessment in the observer-POSAS was also good with 12.9 ± 4.8 (minimum 7, maximum 70; n = 32). Elasticity was rated best (1.47 ± 0.88; minimum 1, maximum 7) and scar pigmentation (2.34 ± 1.54; minimum 1, maximum 7) worst. No correlations with a complication were found.

CONCLUSION

Direct wound closure stretching rhinoplasty is a safe method, especially for defect coverage in the upper two thirds of the soft tissue covering the nose, which in most cases achieved a good cosmetic result.

Technical Refinements with the Use of Biologic Healing Agents

Soft tissue defects resulting from trauma, vascular disease, burns, and postoncologic resections require reconstructive surgery for appropriate wound coverage and support. Dermal substitutes have been applied to a vast array of reconstructive settings across nearly all anatomical areas with demonstrable success. However, they require meticulous handling and operative technical expertise to optimize management of these soft tissue defects. In this review, we will address three dermal substitutes, their operative techniques, and their surgical applications.

Complete division of the pedicle of the forehead flap is possible after 1 week of engraftment in selected patients

Background

Recent studies have demonstrated that early division of the forehead flap (FHF) is possible if angiography is performed or a remnant of the pedicle is left behind. Whether or not careful selection of patients allows for complete division of the pedicle has not been studied.

Objective

To assess if careful selection of patients allows for early complete division of the FHF.

Methods

The exclusion criteria were trauma in the donor region, full-thickness defects, or a larger cartilage grafting. In the selected patients, complete division of the FHF pedicle was performed at early time points, when the pedicle was clinically engrafted (n = 12).

Results

The median age of the patients was 80 years ± 8. The average size of the wounds was 6.6 cm² ± 4.0. The complete division of the pedicle was performed in 10 patients after 7 days, 1 patient after 8 days, and 1 patient after 11 days (median 7.4 days ± 1.1). One patient developed a wound infection, and 1 suffered from postoperative bleeding. The latter patient was the only 1 who required debulking in a third surgical procedure. No necrosis or flap failures were observed.

Limitations

Retrospective, single-center study.

Conclusion

Careful selection allows for complete early division of the pedicle of FHF.
