This continuing medical education article reviews the features, management, and prognosis of cutaneous squamous cell carcinoma with an emphasis on high-risk squamous cell carcinoma and data from the past 3 years. This review will discuss the primary tumor management, high-risk features of a squamous cell carcinoma, changes to the American Joint Committee on Cancer staging system, and the utility of sentinel lymph node biopsy, and critically review the evidence regarding adjuvant therapy.

After studying this article, the participant should be able to 1. Describe the pathogenesis of hidradenitis suppurativa. 2. Discuss perioperative multimodal therapy of hidradenitis suppurativa, including medical optimization. 3. Determine an appropriate surgical plan with excision and reconstruction based on hidradenitis suppurativa severity, size, and anatomical location.

Successful treatment of hidradenitis suppurativa requires a multidisciplinary team approach and multimodal therapy.

Pure skin perforator and superthin flaps have been reported and are becoming popular, as they allow one-stage thin skin reconstruction even from a thick donor site. However, currently reported elevation procedures use proximal-to-distal dissection requiring free-style perforator selection and primary thinning procedures. With distal-to-proximal dissection using the dermis as a landmark for dissection plane, it is expected that elevation of pure skin perforator or superthin flaps can be simplified.

Patients who underwent pure skin perforator or superthin flap transfers with the subdermal dissection technique were included. Flaps were designed based on location of pure skin perforators visualized on color Doppler ultrasound, and elevated just below the dermis under an operating microscope. Medical charts were reviewed to obtain clinical and intraoperative findings. Characteristics of the patients, flaps, and postoperative courses were evaluated.

Thirty-six flaps were transferred in 34 patients, all of which were elevated as true perforator flaps (superficial circumflex iliac artery perforator flap in 29 cases, other perforator flaps in seven cases). Mean ± SD flap thickness was 2.24 ± 0.77 mm (range, 1.0 to 4.0 mm). Skin flap size ranged from 3.5 × 2 cm to 27 × 8 cm. Time for flap elevation was 27.4 ± 11.6 minutes. All flaps survived without flap atrophy/contracture 6 months after surgery, except for two cases of partial necrosis.

The subdermal elevation technique allows straightforward and direct elevation of a pure skin perforator or superthin flap within 30 minutes on average without the necessity of primary thinning.

The updated knowledge of perforasome anatomy and the evolution of microsurgical techniques have enabled surgeons to safely harvest a thin flap. Recently, the anterolateral thigh perforator flap, the current workhorse in soft-tissue reconstruction, has started to be designed and harvested on the superficial fascia, which divides the deep from the superficial fat. ABT-199 mouse This allows elevation of a very thin flap tailored to the defect. Faithful to the ultrathin concept, in an attempt to make flap dissection simpler and safer, the authors describe a revisited harvesting technique of superthin anterolateral thigh perforator flap. This study presents the outlined technique performed in 16 patients with complex soft-tissue defects after trauma or tumor ablation. All of them underwent primary reconstruction using superthin anterolateral thigh perforator free flaps by superficial fascia elevation harvested according to the described surgical procedure. Complications and functional outcomes were assessed. The authors' series of anterolateral thigh perforator superthin flaps demonstrated an overall 100 percent survival rate. Of 16 anterolateral thigh perforators, 12 (75 percent) had no complications and four (25 percent) had minor complications. No major complications such as total flap loss requiring additional salvage surgery were reported. In no case was secondary debulking performed. The superthin anterolateral thigh perforator flap harvested with the described approach was used successfully in microsurgical reconstruction, providing an excellent outer skin cover tailored to the defect. The dissection procedure was safe, quick, simple, and free of major complications. With minimal donor- and recipient-site morbidity, it provided great aesthetic results, avoiding secondary operations.

Skin is one of the target tissues of rejection in face transplants and, because of its easy accessibility, has become the gold standard in the diagnosis of rejection. The allograft contains deeper tissues where rejection can occur, but samples cannot be obtained because of difficult access. Deep tissue changes were monitored on computed tomographic scans of the midface in six face transplant recipients with the help of image segmentation. The maxillary sinus was identified as a dynamic anatomical compartment. Observed changes in volume of the aeration relative to the opacification (aeration coefficient) of the maxillary sinus were quantified with the help of image segmentation. Changes in the aeration coefficient as a surrogate of mucosal swelling were quantified and related to time, treatment, and skin rejection grade. Lower aeration coefficients were found only in patients with transplanted maxillary sinus mucosa. Pathologic changes were not observed in face transplant recipients with a native maxillary spatients who receive parts of the sinonasal tract. The authors identify a potential radiologic biomarker of deep tissue allograft rejection. In the future, the proposed methodology might prove useful in monitoring deeper dynamic tissue changes in vascularized composite allografts and might help in designing patient-specific, individualized treatment strategies.

Functional and aesthetic nasal operations are some of the most common plastic surgery procedures performed in the United States. The purpose of the study was to evaluate the effects of septoplasty, septorhinoplasty, and rhinoplasty procedures on postoperative olfactory function and their relationship to nasal airflow and quality of life.

A systematic review and meta-analysis was performed evaluating olfactory function following nasal surgery. Preoperative and postoperative values for olfaction, nasal airflow, and quality of life/nasal symptoms were analyzed. The effect size was calculated from each study and used for meta-analysis. As studies evaluated patients at different points in the postoperative period, the latest time point reported by each study was used in the meta-analysis. The 95 percent confidence interval of the effect size was calculated for each study. Study quality was assessed using the Jadad and Methodological Index for Nonrandomized Studies instruments. All included studies were Level of Evidence II.
