Waleed H Ezzat, Sara W Liu
Importance: Nasal reconstruction after Mohs surgery is a unique challenge in that it must satisfy both functional and aesthetic goals. Despite some advocacy in the literature for using structural reinforcement to achieve both functional and aesthetic outcomes in soft-tissue reconstruction, no study has validated this claim by comparing reconstruction with and without structural support. Objective: To evaluate the effectiveness of and need for structural reinforcement when reconstructing the nasal alar and sidewall subunits...

<p>Surgical defects located within 5 mm of the nasal alar margin are at risk for alar elevation or collapse of the external nasal valve during wound healing. To reduce the chance of such complications, free cartilage grafts may be used as part of the reconstruction. However, if the defect is large enough so that the free cartilage graft does not fill most of the defect, wound contraction can still lead to alar displacement. In these situations, skin may need to be recruited from either the forehead or cheek in the form of an interpolation flap to cover both the free cartilage graft and the residual cutaneous defect...

The paramedian forehead flap is a great option for restoration of complex nasal defects. For full-thickness defects, it may be used alone or in combination with other methods. We present a patient with a basal cell carcinoma on the distal nose treated by Mohs micrographic surgery, and a resulting full-thickness defect repaired with paramedian forehead flap combined with a hinge flap. For optimal results with the paramedian forehead flap, adequate surgical planning, patient orientation and meticulous surgical technique are imperative...

Full-thickness defects of the entire nasal ala, including the rim, can be challenging to reconstruct. A forehead flap may provide a more imperceptible and natural-appearing reconstructed nasal ala. Previously, many authors have insisted adding cartilaginous infrastructural support for an entire, full-thickness defect to keep the postoperative alar structure symmetrical. They finally use a forehead flap after thinning of the distal covering portion subcutaneously, possibly for a Caucasian-type nasal ala. However, Asian skin has a thicker and more compact dermis than that of Caucasian skin, and the Asian ala is rounder and thicker...

Palatal defects following congenital anomalies, traumatic injuries, benign and malignant pathologies frequently require resection and reconstruction. Reconstruction of these defects is challenging and complex due to the amount of tissue left for primary closure after excision, compromised vasculature as on repaired cleft palate and limited pedicled flaps around the lesion. Tongue flap though doesn't fulfil all the ideal requirements of a flap, however because of its flexibility, good blood supply and position it can be considered as the best among other flaps for reconstruction of oral and palatal defects...

The objective of this study was to describe outcomes for patients who underwent titanium mesh reconstruction of full-thickness nasal defects without internal lining repair. This is a retrospective cohort study. Patients with through-and-through nasal defects were identified at a single academic institution between 2008 and 2016. Nasal reconstruction was performed with either titanium mesh and external skin reconstruction without repair of the intranasal lining or traditional three-layer closure. Five patients underwent titanium mesh reconstruction and 11 underwent traditional three-layer repair...

The final cosmetic appearance of nasal reconstruction scars is of paramount importance to both the patient and surgeon. Ideal postreconstruction nasal scars are flat and indistinguishable from surrounding skin. Unfortunately, even with meticulous surgical execution, nasal scars can occasionally be suboptimal. Abnormal fibroblast response can lead to hypertrophic nasal scars, and excessive angiogenesis may lead to telangiectasias or an erythematous scar. Imperfect surgical closure or poor postoperative management can lead to surgical outcomes with step-offs, depressions, suture marks, or dyspigmentation...

Nasal reconstruction for subtotal and total rhinectomy defects is a challenging endeavor, which requires technical finesse, a keen artistic eye, and the ability to anticipate long-term changes that accompany postoperative healing. While local and regional flaps have traditionally been utilized to reconstitute missing nasal elements, certain situations may not provide sufficient or acceptable tissue for optimal reconstruction. In these situations, the three major components of the nose-lining, structural support, and external skin-may require reconstruction with tissues harvested from distant sites through microvascular free tissue transfer...

Reconstruction of full-thickness nasal defects has been the subject of surgical inquiry and innovation for over 2,000 years. The replacement of the internal nasal lining is a critical feature of complex nasal reconstruction. Successful reconstruction can prevent cicatricial contraction, external distortion, and internal stenosis. An array of reconstructive possibilities has been described, including cutaneous, mucosal, and fascial options. The challenge to the reconstructive surgeon is to select the repair that maximizes internal stability, while maintaining a patent nasal airway, minimizing morbidity, and meeting patient expectations...

Artemus Cox, Matthew Fort
The challenges of nasal reconstruction are readily apparent to any surgeon who has undertaken this task. Defects involving multiple subunits of the nose usually require adjacent tissue transferred to the wound typically in the form of a forehead flap or other local flaps. Herein, we describe current thought on the subunit principle and the application of local flaps and grafts in reconstructing larger superficial defects of the nose. Primary attention is paid to analysis and patient counseling.

The nose is a complex, three-dimensional structure that is supported by a framework of osseous and cartilaginous structures. Disruption of this framework can result in nasal deformity and functional deficits. Nasal reconstruction requires restoration of the osseous and cartilaginous framework. This requires careful preoperative assessment of the nasal defect and understanding the nasal and facial aesthetics that are supported by the osseous and cartilaginous support structures. Structural grafts can be classified as restorative, supportive, or contouring...
