Nasal Reconstruction after Mohs Cancer Resection: Lessons Learned from 2553 Consecutive Cases

Aesthetic Outcomes of Nasal Reconstruction Following Mohs Excision

PURPOSE

Nasal reconstruction following Mohs excision can be performed with several techniques. The authors sought to evaluate which procedures provided the most aesthetic results.

METHODS

A retrospective review was conducted on patients who underwent primary nasal reconstruction by the senior author following Mohs excision over an 8-year period. Data collected included patient demographics, smoking status, defect size, reconstruction method, and photo documentation. Patients were categorized into the following 4 groups: full thickness skin grafts (FTSG), local skin flaps, cheek flaps, and paramedian forehead flaps. Postoperative photos were assessed by a blinded plastic surgeon using a Likert scale for aesthetic outcomes. Ordinal logistic regression models were used to assess the adjusted effects of reconstructive technique, age, sex, defect size, and smoking status on outcome ratings.

RESULTS

One hundred forty-four (144) cases met inclusion criteria. The average patient age was 65.3 years. Distribution included 42 FTSGs, 60 local flaps, 13 cheeks flaps, and 29 forehead flaps. Reconstructions using local skin flaps and forehead flaps were statistically more likely to be rated favorably compared to those using FTSGs [local flaps: odds ratio (OR) = 2.79 (1.29-6.17), P = 0.011; FTSGs: OR = 2.84 (1.05-7.86), P = 0.043]. Larger defects negatively affected outcomes [OR = 0.90, confidence interval = (0.23-0.81), P = 0.019] in addition to any smoking history [OR = 0.43, confidence interval = (0.82-0.98), P = 0.019].

CONCLUSIONS

Local skin flaps and forehead flaps provide favorable aesthetic results in comparison to FTSGs for nasal reconstruction.

Reconstruction after Nasal Skin Cancer Resection: Nasal Obstruction and Associated Factors

Background: Equal attention must be given to nasal aesthetics and function when reconstructing nasal defects after skin cancer resection. Little data exist on functional nasal outcomes following nasal reconstruction. Learning/Study Objective: Describe and analyze factors contributing to functional outcomes following nasal skin cancer defect reconstruction. Design Type: Retrospective review. Methods: Patients who underwent reconstruction of Mohs nasal defects were included. Reconstruction methods included primary closure, skin grafts, and local and interpolated flaps. Both subjective reports and physician-noted exam findings suggestive of nasal obstruction were noted. The obstructive domain of the Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS-O) was administered preoperatively and at follow-up intervals. Results: In total, 193 patients met the inclusion criteria. Female sex, medial or lateral ala primary defect subunit, and auricular cartilage use were associated with increased risk of postoperative nasal obstruction within the first year on multivariate analysis, while reconstruction with a skin/composite graft was associated with lower risk of obstruction. Average time from reconstructive surgery to first report of obstruction was 116 days, and time to reported resolution was 235 days. Conclusion: The incidence of nasal obstruction following nasal defect reconstruction is low. Female sex, ala involvement, and auricular cartilage may increase the risk of nasal obstruction postoperatively.

Expanded Uses of the Dorsal Nasal Flap: Redefining the Nasal Reconstruction Algorithm

Background

Defects of the nose present complex reconstructive challenges to the plastic surgeon. We present our experience with using the dorsal nasal flap (DNF) to provide a durable reconstruction even in sizable defects that would otherwise be considered necessitating a paramedian forehead flap.

Methods

We conducted a retrospective chart review of patients who underwent reconstruction by DNF following resection of skin cancers on the nose. Six flap-type modifications are described: limited, standard, double, combined, extended, and readvanced.

Results

From 2015 to 2021, a total of 51 patients underwent DNF reconstruction. The most frequently used flap types were the limited or standard configurations. There is a general trend of utilizing increasingly complex flap types to reconstruct larger defect sizes, as depicted in our reconstructive algorithm. There were no flap losses.

Conclusions

Our study expands the indications of the DNF and redefines the nasal reconstruction algorithm. However, our proposition is not absolute in that one must consider tissue pliability and the location of the defect.

Cost-Effectiveness Analysis of Operating Room and In-Office Reconstruction of Skin Cancer Defects

OBJECTIVE

Reconstruction of skin cancer and Mohs micrographic surgery (MMS) defects of the head and neck is performed in both in-office and operating room (OR). This study intends to understand cost differences between reconstructive surgery for skin cancer defects in the OR and clinic to perform a cost-effectiveness analysis with single-institution patient satisfaction data.

STUDY DESIGN

Population-based retrospective analysis of cost data and an institutional, prospective survey of patient satisfaction.

SETTING

National insurance database and institutional survey.

METHODS

The Merative® MarketScan database was queried to identify claims involving the reconstruction of skin cancer defects of the head/neck between 2013 and 2020 for cost-analysis by setting (OR vs clinic). Patients undergoing operative and clinic-based reconstruction of MMS defects by 3 different surgeons at a single institution in 2023 were surveyed for satisfaction using a 5-point Likert scale. Data was coupled for cost-benefit analysis. Analysis was performed using propensity-matched samples.

RESULTS

Using Marketscan, 1206 patients were analyzed for cost data. OR cases had a higher median baseline cost of $2308 (interquartile range [IQR]: 1484-3889) compared to procedures in the office (median $987, IQR: 784-1454, P < .001). Survey data from 116 patients revealed no significant difference in scores between OR and clinic cases (clinic: 4.57 vs OR: 4.60, P = .8752). Using propensity-matched subsets, providers incur an additional $4744 for a reduction in satisfaction of 0.083 when performing cases in the OR.

CONCLUSION

Lower cost is associated with reconstructive procedures performed in the office. This study is the first cost analysis of head and neck skin cancer reconstruction based on procedural settings and will be valuable to surgeons in considering practice patterns and resource utilization.

Reconstruction of Small Nasal Defects

The nose maintains a central importance in both functional and aesthetic human anatomy. With such importance comes numerous possible defects with equally plentiful techniques available for repair. One of the most common causes for nasal reconstruction is Mohs micrographic surgery to excise basal and squamous cell carcinomas. Generally, these procedures create small defects which can be repaired via skin graft or flaps with possible assistance from biologic agents.

Postoperative Cosmetic Scores and Revision Rates After Nasal Mohs Reconstructive Surgery

OBJECTIVE

Few studies have examined the impact of preoperative and surgical factors on the change in cosmetic survey scores after nasal Mohs reconstruction using a subset of the 10-item Standardized Cosmesis and Health Nasal Outcomes Survey-Cosmesis (SCHNOS-C). We aim to determine preoperative and surgical factors that impact cosmetic outcomes following Mohs nasal reconstruction.

STUDY DESIGN

Retrospective analysis.

SETTING

Nasal Mohs reconstruction patients at a tertiary medical center.

METHODS

All patients receiving Mohs reconstruction of any nasal subunit at a tertiary medical center were analyzed. Variables collected included demographic and Mohs defect/reconstruction characteristics. Primary outcomes were changes in cosmetic (SCHNOS-C) scores and revision rates. Multivariable analysis was used to identify independent predictors of cosmetic scores/revision.

RESULTS

We included 296 patients for analysis. On multivariable logistic regression, factors contributing to better final cosmetic scores were receiving a skin/composite graft (odds ratio [OR]: 0.22, 95% confidence interval: 0.06-0.68, P = .014) compared to a local flaps. Women were more likely to have worsening cosmetic scores (OR: 2.27, 1.06-4.99, P = .037). Only initial cosmetic scores independently predicted receiving any revision (OR: 1.11, 1.03-1.20, P = .006).

CONCLUSION

Average SCHNOS-C scores after nasal reconstruction of Mohs defects are low. Only worse patient reported SCHNOS-C scores predicted revision. It is important to understand preoperative and surgical factors that affect cosmetic outcomes to optimize patient counseling and reconstructive planning. Patient perception is a key factor in predicting revisions.

A Surgical Conundrum: Addressing a Large Nasal Defect Following Mohs Micrographic Surgery

Managing large nasal defects following Mohs surgery presents complex reconstructive challenges due to the nose's prominent and visible nature. These cases require a careful balance of preserving structural integrity, optimizing cosmetic outcomes, and maintaining vascular health. In situations where primary closure is impractical due to defect size and location, innovative techniques like the double rhomboid transposition flap offer versatile solutions, addressing both aesthetic concerns and functional requirements. The double rhomboid flap allows surgeons to achieve continuity of surrounding tissue, ensuring aesthetically pleasing texture, color, and thickness while minimizing complications like skin tension and potential airway issues. This case highlights the reconstructive challenges faced in managing large nasal defects following Mohs micrographic surgery for basal cell carcinoma. An 84-year-old male presented with a significant nasal defect following Mohs surgery that involved the dorsum, sidewall, tip, and ala, complicating primary closure due to skin tension and cosmetic concerns. Utilizing a double rhomboid transposition flap technique allowed for effective aesthetic and structural reconstruction, addressing skin tension and preserving nasal symmetry. This case emphasizes the importance of tailored reconstructive strategies to achieve optimal cosmetic and functional outcomes in complex nasal Mohs defects.

Forehead Flap Practices: A Cross-Sectional Survey of Facial Plastic and Reconstructive Surgeons

Background: The paramedian forehead flap (PMFF) is a well-established technique utilized for reconstruction of complex nasal defects. Objective: To identify the different techniques and management of patients undergoing PMFF reconstruction and compare these with current literature. Methods: Members of the American Academy of Facial Plastic and Reconstructive Surgery were sent a practice survey highlighting various nuances in PMFF reconstruction. The survey included questions about flap design, operative techniques, and perioperative care. Results: In total, 172 responses were received (14% response rate). Mean years of practice after fellowship was 15.8 years with most respondents performing either 1-5 (33.1%) or 6-10 (27.3%) PMFFs per year. Common practices included the use of general anesthesia, elevation of PMFF in the subgaleal plane (59.6%), and pedicle division at 3 weeks (80%) (p < 0.001). Complication rates ranged between 1% and 5%. The nose was the most common site for revision (p < 0.001) and the average number of secondary procedures after forehead flap division was 1.1 (standard deviation 0.81). The most variability in responses was seen for methods of internal lining reconstruction. Conclusion: Reconstructive surgeons frequently divide the PMFF pedicle at 3 weeks or later and have variable approaches to reconstruction of the internal lining with low complication rates overall.

State of the Evidence for Facial Skin Cancer Reconstruction

This review provides a comprehensive presentation of the evidence available in facial reconstruction post-Mohs micrographic surgery. Given the large diversity in post-Mohs reconstruction, there are limited guidelines in the management of defects. The aim of the present work is to provide a review of the best evidence as it pertains to several considerations in facial reconstruction. Data suggests that Mohs micrographic surgery and many reconstructive procedures can be performed as outpatient procedures under local anesthesia, with narcotic pain medication only given in certain patient populations following a minority of reconstructive procedures. Perioperative and topical antibiotics are generally not indicated. Aspirin and warfarin can generally be continued for most reconstructive procedures, but clopidogrel and novel anticoagulants may predispose to increased bleeding complications. Delayed reconstruction appears to be safe, although data are discordant on this topic. No specific wound closure technique or suture choice appears to be consistently superior. Given the lack of robust comparative studies, consistent methodology, and variable defect sizes/locations, no robust evidence-based guidelines can be generated for reconstruction techniques of facial subsites.

[Translated article] Anatomy and Design of Musculocutaneous Flaps in Nasal Reconstruction

The nose is a common site for skin tumors. The main arteries that supply the nose extend through the subcutaneous tissue. Submuscular dissection facilitates the design of safe, reliable musculocutaneous flaps that adapt well to the morphology of nasal defects. The diversity of these flaps makes them the first choice for reconstructing defects in more complex regions, such as the inner canthus of the eye and the nasal ala. We describe the surgical design of the procerus, V-Y nasalis, and lateral wall nasalis musculocutaneous flaps used to repair defects following tumor excision. The descriptions are illustrated by photographs taken by the authors during procedures and in cadaveric dissections.

Development of a Risk Prediction Model for Complications Following Forehead Flaps for Nasal and Periorbital Reconstruction

BACKGROUND

Forehead flaps are a workhorse for nasal reconstruction, but complications occur in up to 30% of patients and risk factors are not well characterized. This study aimed to identify risk factors for complications, and provide clinicians a method to stratify patient risk to facilitate shared decision-making.

MATERIALS AND METHODS

This retrospective study included patients who underwent forehead flaps between 2007 and 2020. Demographic and treatment characteristics were abstracted, in addition to clinical outcomes data. Multivariable regression was conducted, with step-wise variable elimination to determine inclusion in the final model. From the final regression, a risk-stratification scheme was developed.

RESULTS

One hundred ninety-seven patients underwent forehead flap reconstruction, with a mean age of 68.5 years. Mean follow-up time was 42 months. There were 50 (25.4%) patients who developed a complication, including impaired nasal function (18.8%), flap congestion (5.1%), infection (2.5%), poor donor site healing (2.5%) wound dehiscence (2.0%), and flap congestion (1.5%). On univariate analysis, female sex, immunosuppression, prior radiotherapy, and larger resection area were associated with complications ( P <0.05). On multivariable analysis, female sex [odds ratio (OR): 3.89, P <0.001], hypoalbuminemia (OR: 3.70, P =0.01), and prior wide local excision (OR: 3.62, P =0.04) were predictors of complications. A clinical calculator was developed incorporating these risk factors, with a C-statistic of 0.85, indicating strong predictive value.

CONCLUSIONS

We conducted the most comprehensive review of risk factors for the development of complications after forehead flap reconstruction. From this analysis, a novel, implementable, risk-stratification scheme was developed to equip surgeons with the ability to provide individualized risk assessment to patients and address preoperative comorbidities to optimize outcomes.

An Innovative and Economical Device for Ischemic Preconditioning of the Forehead Flap Prior to Pedicle Division: A Comparative Study

BACKGROUND

 Ischemic preconditioning of the forehead flap prior to pedicle division helps to improve angiogenesis. Clamping the pedicle by a clamped rubber band with vessel forceps is often clinically applied. However, the severe pain and unstable blocking effect influenced the preconditioning process. In this study, we described an innovative device designed for ischemic preconditioning and compared its efficacy with the clamped rubber band.

METHODS

 The device consists of a self-locking nylon cable tie with a buckle and a rubber tube. The rubber tube is fed over the cable tie to act as a soft outer lining and the cable tie is tightened across the pedicle to block the perfusion for ischemic preconditioning. This device and the standard clamped rubber band were applied respectively before division surgery. The constriction effect, reliability, reproducibility, and the patients' pain tolerance were compared.

RESULTS

 A total of 20 forehead flaps were included. The cable tie had less incidence of loosening (7.7% vs. 16.6%, p < 0.05) and maintained the pressure more effectively. The pain score for the nylon cable tie was significantly lower than the clamped rubber band (4.25 ± 1.02 vs. 6.75 ± 1.12, p < 0.05), especially for 10 pediatric patients (4.50 ± 0.85 vs. 8.10 ± 1.20, p < 0.01). All 20 pedicles were successfully divided at 19 to 22 days with no surgical complications.

CONCLUSION

 Compared with the clamped rubber band, the cable tie produces a more reliable and reproducible ischemic preconditioning effect. It is also better tolerated by the patients. Therefore, we recommend using the nylon cable tie as the preferred device for ischemic preconditioning of the forehead flap.

Use of Biologic Agents for Lip and Cheek Reconstruction

The unique requirements of reconstructing cheek defects, often with its proximity to the mobile elements of the face including the lip and the eyelid, have been met very handily with the directed and thoughtful use of biologic wound healing agents. One of the key advantages of these agents is their ability to provide coverage for the mobile elements of the cheek and the lip in patients with multiple co-morbidities. These agents are successfully used where the standard cheek closure techniques including cervicofacial advancement flap are contraindicated due to its anesthetic requirement. Additionally, lip reconstruction involves examining the lip's three anatomic layers: mucosa, muscle, and skin. The defects must be planned for reconstruction based on the involvement of these layers. This paper serves to introduce the use of biologic wound healing agents depending on the involvement of these layers. The authors provide specific illustrations of these agents based on defect location, tissue involvement, and severity of the defect to help with procedural planning to reconstruct a very aesthetically involved part of the face.

Use of Biologic Agents in Nasal and Scalp Reconstruction

Oncologic reconstruction of the nose and scalp following Mohs micrographic surgery poses a significant challenge for plastic surgeons. While these defects are traditionally reconstructed using primary closure techniques, skin grafts, local flaps, pedicled flaps, and free tissue transfer, the incorporation of biologic healing wound agents such as Integra and Cytal provides patients and surgeons with alterative reconstructive options without additional donor site morbidity. Herein, we review the use of biologic agents used in soft tissue reconstruction of the nose and scalp following Mohs surgery.
