A Lifeboat for Failed Nasal Reconstructions: The Supraclavicular-Submental Sandwich Flap.

Many failures in total or subtotal nasal reconstruction result from an underestimation of the amount of skin required for an adequate result, especially for sufficient lining. Such planning errors usually lead to poor results, with exposure of structural grafts, infection, scar retraction, airway obstruction, and finally loss of projection and shape of the reconstructed nose. Reconstruction options for cases in which previous attempts have failed are always limited, as well as in cases of trauma or burns affecting the soft tissues of the forehead and face. In such complex situations, one may employ free flaps or tissue expansion, but such resources may not be always available. We describe a technique indicated for salvage surgeries in patients whose previous nasal reconstructions have failed, allowing a generous amount of tissue transfer for the nasal region. The technique combines the use of supraclavicular and submental flaps, with simple execution, not requiring microsurgical skills or devices such as tissue expanders. Done in three stages, the described technique provides enough skin for a total nasal reconstruction. The final result is obtained after subsequent refinements, and the total number of procedures is equivalent to when more sophisticated techniques are employed, such as tissue expansion or microsurgery.

A 10-year experience in microsurgical reconstruction of the nose with a lower extremity flap

BackgroundTraditionally, radial forearm free flaps are utilized for nasal lining reconstruction when local flaps cannot provide adequate coverage. However, according to our clinical observation, the skin of the forearm flap is relatively thin and prone to collapse. We present a series of nasal reconstructions using free flaps harvested from the lower extremities to determine if the thick flap could provide more support and decrease the tendency of airway collapse. MethodsFrom March 2011 to July 2021, we identified 15 patients who underwent total or subtotal nasal reconstruction with free flap from the lower extremities (10 anterolateral thigh flap, 4 medial sural artery perforator flap, and 1 profunda artery perforator flap). We included 15 patients who underwent free forearm flap reconstruction as controls. The Nasal Obstruction Symptoms Evaluation (NOSE) score was utilized to subjectively evaluate the degree of nasal obstruction symptoms. ResultsThe lower extremity group had a lower NOSE score than the forearm group (25.4 vs. 40). It took more time (6.5 vs. 4.2 months) and more surgeries (4.6 vs. 2.6) from the first free flap reconstruction till forehead flap reconstruction in the lower extremity group than in the forearm group, although the total number of surgeries was comparable between the 2 groups (7.2 vs. 8.1). ConclusionsUtilizing free flaps from the lower extremities in total or subtotal reconstruction of the nasal lining may decrease the tendency of flap collapse and alleviate airway obstruction symptoms and may also allow reconstruction of surrounding defects simultaneously compared with using forearm flaps.

A Novel Computer-Aided Design/Computer-Aided Manufacturing (CAD/CAM) 3D Printing Method for Nasal Framework Reconstruction Using Microvascular Free Flaps.

The need for a total or subtotal nose resection represents a dramatic situation for any patient and a challenge for the reconstructive surgeon. Because even in the most skillful hands, an optimal result may be difficult to achieve. In this way, sometimes a free flap reconstruction is needed. A subtotal nasal reconstruction is presented using a fasciocutaneous free flap supported by computer-aided design (CAD), computer-aided manufacturing (CAM), and novel 3D printed guide to recreate the nasal cartilage framework. A successfully free flap reconstruction of the nasal framework was achieved supported by the CAD/CAM 3D printed template. We present a novel approach for nasal total or subtotal reconstruction using a CAD/CAM 3D printed model to create the nasal framework, based on the anatomical and radiological evaluation of the patient.

Microsurgical Techniques and Postoperative Outcomes After Total and Subtotal Nasal Reconstruction: A Systematic Review.

Multiple microsurgical techniques for nasal reconstruction have been described in the literature. Given the gaps in the literature regarding evidence-based reviews for total and subtotal nasal reconstruction using microsurgical techniques, the purpose of this study was to provide a thorough presentation of the most popular microvascular techniques and their outcomes (functional and aesthetic) for total or subtotal nasal defects. A systematic search was performed using PubMed, Google Scholar, and Cochrane Library on free flap techniques for restoration of nasectomy defects. The keywords were "nasal reconstruction," "nose," "nasectomy," "rhinectomy," and "microvascular." Inclusion criteria for analysis in the study were the largest clinical case series published in English within the past 15 years with more than 8 patients.Studies were analyzed for patient demographics, etiology of nasal loss, surgical approaches to reconstruction, outcomes, and complications. The current study was registered at the International Prospective Register of Systematic Reviews and conducted based on the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. The initial search yielded 302 results. Eleven articles with a total of 232 patients met the inclusion criteria. The radial (n = 85) and ulnar forearm flaps (n = 20), auricular helical rim (n = 87), and anterolateral thigh flap (n = 30) were the most commonly reported free flaps in nasal reconstruction. The main etiologic factors were malignancy and trauma. The most common complication was partial flap necrosis. The auricular helical and radial forearm flaps represent the most used free flaps for total and/or subtotal nasal defects with satisfactory patient outcomes.

Total nasal reconstruction with a forehead flap: Focusing on the facial aesthetic subunit principle

The nasal aesthetic subunit principle has been widely accepted as the standard for nasal reconstruction with forehead flaps. However, in our experience, one's impression of a reconstructed face can easily be represented by the nose's entire appearance rather than a single nasal component. Accordingly, we hypothesized that total nasal reconstruction focusing more on the facial aesthetic subunit principle would be superior to focal nasal subunit partial reconstruction. Here, we investigated the indication range of total nasal reconstruction and analyzed its effectiveness. Between July 2006 and December 2017, 32 patients who underwent total or subtotal nasal reconstruction were recruited. The total nasal reconstruction group (n = 20) was treated according to our modified facial aesthetic unit concept, while the subtotal reconstruction group (n = 16) was treated according to the nasal aesthetic subunit principle. Using retrospective reviews, we compared surgical details and aesthetic, and functional outcomes with visual analog scale scores. In aesthetic evaluation, nose contour (p = 0.009), nasal symmetry (p = 0.001), and nostril shape (p = 0.041) were superior in the total nasal reconstruction group. Satisfaction regarding the nose (p = 0.036) was significantly higher than that regarding the forehead and labial folds in the total group. Regarding function, there were no significant intergroup differences in nasal airflow, snoring, or olfaction. We suggest that total nasal reconstruction is not a strategy to avoid because of its aggressive nature. For selected suitable patients, the use of the total nose reconstruction focusing on our one nose concept can be a successful surgical option, and the reconstructed nose can be visualized as a real part of the face.

The First Dorsal Metacarpal Artery Free Flap for Salvage of Nasal Reconstructions.

The first dorsal metacarpal artery free flap is widely known for its use as a pedicled flap in thumb and hand reconstruction; however, its potential for use as a free flap is less well known. We previously described successful use of the first dorsal metacarpal artery free flap for salvage of a subtotal nasal reconstruction. In this retrospective study, we have expanded our experience to 7 consecutive cases in which a FDMFF was utilized to salvage a nasal reconstruction. Single island flaps were used in 6 of 7 cases, in one case a double island configuration was utilized. Sites restored included the columella (5 patients), membranous septum (1 patient), and nasal sidewall (1 patient). Vascular repairs were to the angular artery and vein (2 patients) or the vascular pedicle of a prior free flap (5 patients). There were no flap failures or major complications. The dorsal hand donor sites were uniformly closed using full-thickness skin grafts. All of the salvage nasal reconstructions were brought to a successful completion. Donor site morbidity was minimal with no compromise in hand function noted. Owing to its thinness, consistent anatomy, ease of harvest, and minimal donor site morbidity, the FDMFF has proved to be a very useful flap for restoration of small, but critical, nasal defects arising during the course of nasal reconstruction.

Nasal Reconstruction With Two Stages Versus Three Stages Forehead Fap: What is Better for Patients With High Vascular Risk?

In nasal reconstruction, it is necessary to replace all anatomic layers in order to reinstate correct aesthetics. The most apt donor site to use in order to cover the nose has been recognized as forehead skin. Traditionally 2 phases are required to reconstruct the forehead flap; however, an intermediate third phase was described by Millard which is between transfer of the flap and division of the pedicle. These methods will be compared in this study with regard to both complication rates and aesthetic results in high vascular risk patients.46 patients were enrolled in the study, all of whom were undergoing either total or subtotal nasal reconstruction from January 2001 to March 2018. The 2-step technique (2S Group) was performed on 30 patients and the 3-step technique (3S Group) was performed on 16. Evaluation questionnaires were completed by patients and a plastic surgeon who was extraneous to the study to evaluate aesthetic satisfaction. Complications other than flap necrosis such as infection, wound dehiscence and hematoma were recorded. VAS and Likert mean values, used to evaluate aesthetic satisfaction, were examined with a Student t test and were discovered to be relevant. Complication rates studied with Fisher exact test showed no statistically significant difference between the 2 groups. The 3-phase method for nose reconstruction using a forehead flap represents a better functional and aesthetic option for patients at high vascular risk.

Pericranial Flap for Inner Lining in Nasal Reconstruction.

The general principle in nasal reconstruction is to reconstruct the 3 layers of skin, cartilage, and mucosa. Reconstructing the inner lining remains a challenge especially when adjacent tissues are not available after tumor resection. The galea and pericranial flaps (PFs) are widely used in anterior skull base reconstructive surgery.We evaluated the use of the PF for the inner nasal lining in an anatomical cadaver study and present its clinical application in patients with benign and malignant tumors of the nose and anterior skull base. Four fresh cadavers were injected with red-colored silicone for determining the pattern of vascularization of supraorbital (SOA) and supratrochlear (STA) arteries of each PF. Four surgical cases (2 nasocranial meningiomas, 1 nasal melanoma, and 1 nasal squamous cell carcinoma) received PF for reconstruction of inner lining. The median distances between the superior orbital rim and the division of the deep and superficial branches of STA and SOA were 8 ± 3.3 mm and 8 ± 3.7 mm, respectively. The maximum measured distance was 11 mm. The SOA provided the longest axial vascularization (70.7 ± 13. 9 mm) compared with STA (35 ± 10.4 mm). Median length of PF for subtotal nasal reconstruction including tip and columella were 70 ± 5 mm and 22.5 ± 3.5 mm, respectively.Three cases were successfully reconstructed with PF up to the distal border of the upper lateral cartilage. In 1 patient, distal necrosis of tip and columella occurred. The blood supply of the PF is mainly based on the SOA arteries. Thus, superficial dissection must end 15 mm above the orbital rim to ensure the survival of the flap. Pericranial flap can be applied for inner lining in combined nasocranial, septal, and nasal defects with extension down to the distal border of the upper lateral cartilage. Vascularization is reliable in flaps up to a length of 70 mm.

Free Anterolateral Thigh Fascia Lata Flap for Complex Nasal Lining Defects

To introduce a novel technique for the reconstruction of complex nasal lining defects using the free vascularized anterolateral thigh fascia lata flap. Free anterolateral thigh fascia lata flaps were used to replace nasal lining in 5 patients with total or subtotal rhinectomy defects. We performed a retrospective medical record review. No flap failure or lining loss was observed, and harvest site morbidity was negligible. Patients achieved satisfactory nasal form and patent nasal airways without a need for repeated revisions. In 2 patients, the anterolateral thigh flap was used simultaneously to restore the midface contour or to repair anterior skull base defects. In this case series, we demonstrate the novel use of vascularized fascia lata to provide viable nasal lining in total and subtotal nasal defect reconstruction. Potential advantages offered by this technique compared with more established methods include (1) single-stage replacement of nasal lining, structure, and skin coverage; (2) fewer additional stages of reconstruction to achieve functional and aesthetic results; (3) thin lining to allow for optimal airway contour; (4) less harvest site morbidity; and (5) development of composite soft tissue, cutaneous, and/or muscle flaps to repair adjacent defects.

Assessment of subtotal nasal reconstruction in a child after 6 years of follow-up

Nasal amputation in the child is infrequent, and the procedure is not clearly defined. Early reconstruction certainly improves the child's life and social integration. The major risk is unsatisfactory growth of the reconstructed nose, which may persuade some surgeons to postpone the operation. The evaluation of this nasal reconstruction in a 5-year-old boy who had undergone subtotal amputation of the nose after 6 years of follow-up tends to confirm the therapeutic choice of early nasal reconstruction in the child. The results were considered quite satisfactory esthetically and psychologically beneficial and are concordant with those of other studies. Early management allowed us to obtain an esthetically acceptable reconstruction with respect to growth, thereby enabling the child to resume his studies rapidly and to achieve good social integration.

Reconstruction esthétique totale du nez et des unités faciales adjacentes par combinaison optimisée lambeaux libres, greffes cartilagineuses et lambeau pédiculé frontal paramédian

Facial reconstruction with only free microvascular flaps has rarely produced an aesthetic result. Menick : "Distant skin always appears as a mismatched patch within residual normal facial skin." In addition, earlier techniques using a single large nasal lining flap or bilateral nasal lining vaults incurred a high incidence of airway obstruction. The authors describe 10 consecutive patients requiring reconstruction of the nasal vestibule and columella lining from October of 1997 through May of 2005. Most of them also required reconstruction of the floor of the nose, the platform on which the alar bases and columella rest, and of the facial units adjacent to the nose. Aesthetic nasal reconstruction used two separate skin paddles to reconstruct the lining for the nasal vestibule and columella, an artistically constructed nasal framework made of cartilage, a forehead flap for cover, and other flaps and grafts to reconstruct adjacent facial unit defects. The average patient age was 41.8 years (range, 10.4 to 65.3 years). Follow-up (from the time of the first operative stage) averaged 26.4 months (range, 4 to 49 months). Nine patients had functional airways and one required nasal airway support with internal silicone tubes. At the time of publication, eight patients had normal-appearing noses and two were awaiting secondary surgery to correct persistent deformity. Microvascular free flaps have proved to be highly reliable and efficacious for restoration of missing elements of the nasal lining and adjacent facial soft-tissue defects in total and subtotal nasal reconstruction. Combined with a forehead flap, this aesthetic approach allows for reconstruction of the center of the face layer-by-layer and facial unit by facial unit. Specific attention is paid to the artistic creation of normal nasal dimensions, proportion, and form using carved and assembled cartilage grafts and by secondary subcutaneous contouring. In addition, this technique produces a patent airway.

Refinements in Nasal Reconstruction: The Cross-Paramedian Forehead Flap

Nasal reconstruction can be a challenge for the plastic surgeon. The forehead flap is the workhorse in nasal reconstruction, providing similar skin color, texture, structure, and reliability. There are disadvantages of the forehead flap, including a difficult arc of rotation, which risks displacement of medial eyebrow hair. The vertical design can encroach on the scalp, incorporating hair into the nasal reconstruction. Forehead flap inset results in an inverted V-shaped scar visible in the glabella region. This article describes the authors' modification of the established oblique paramedian forehead flap. This retrospective study included a consecutive series of patients over an 11-year period (December of 1996 to December of 2007) that underwent nasal reconstruction performed by the primary surgeon (J.A.). Information obtained from chart reviews included age, sex, cause of nasal defect, complications, and revisions. This study population consisted of 94 adults: 54 men (57 percent) and 40 women (43 percent) who underwent nasal reconstruction using the cross-paramedian forehead flap. All flaps were performed for skin cancer reconstruction. Partial flap loss was the most common complication. Tobacco use was associated with half of the complications. Further refinements following forehead flap inset were performed in 50 percent of patients. The cross-paramedian forehead flap is a useful design when planning subtotal nasal reconstruction. It provides a smooth arc of rotation and increased length, avoids an inverted V-shaped glabella scar, and minimizes eyebrow distortion. These modifications of the forehead flap maintain the reliability and versatility of the flap and provide an aesthetically pleasing result.

Subtotal Nasal Reconstruction for Ethmoid Sinus Cancer Defect Using a Fibula Osteocutaneous Free Flap

Use of the auricular composite graft in nasal reconstruction.

We present our experience using conchal composite grafts in major and minor nasal reconstruction. We believe that composite grafts have an important and under-utilized role as an adjunct to the paramedian forehead flap on total and subtotal nasal reconstruction, as well as in providing an internal lining and support in stenosis of the nasal vestibule. The use of a composite conchal graft as an inner lining and support is often preferential to a septal composite or hinge flap that often results in a septal perforation with its associated morbidity. We recognize that a composite conchal graft used for reconstruction of the alar margin provides a suboptimal result after several months. This is because it is not always possible to replace a whole aesthetic subunit and whilst the site the graft is harvested from often allows the correct contour to be chosen, the quality of skin is often different and this can be seen after several weeks when any post-operative oedema has settled.

Forehead Expansion and Total Nasal Reconstruction

Forehead flaps are the method of choice for total nasal reconstruction. However, if adequate skin is unavailable, tissue expansion of this donor site for subtotal nasal reconstruction seems logical, as has been described elsewhere. The literature, however, appears devoid of reports of using this technique when all the nasal structures are absent. We report on 3 patients for whom expanded forehead flaps provided poor long-term results because of late shrinkage.
