The anatomical distribution of non-melanoma skin cancer: A retrospective cohort study of 22 303 Australian cases.

ANZ J Surg 2021 Jun 21. Epub 2021 Jun 21.

College of Medicine and Public Health, Flinders University, Adelaide, South Australia, Australia.

Background: Non-melanoma skin cancers (NMSC) are the most common skin cancers worldwide with research establishing that ultraviolet (UV) radiation influences occurrence. However, recent studies about NMSC tumour frequencies suggested high NMSC predilections in low UV-exposed skin regions.

Methods: The 'Human Surface Anatomy Labeling System' was used to define 100 skin regions to map NMSC locations excised at Flinders Medical Centre (FMC) between 1 January 2012 and 31 December 2017. Read More

Current Trends in Facial Feminization Surgery: An Assessment of Safety and Style.

J Craniofac Surg 2021 May 28. Epub 2021 May 28.

Hansjörg Wyss Department of Plastic Surgery, New York University Langone Health, New York, NY.

Background: Facial feminization surgery (FFS) plays an instrumental role in the process of gender affirmation. These procedures are becoming increasingly appreciated for their ability to improve patient satisfaction and gender identity in a way that alleviates gender dysphoria and improves the quality of life. Despite the recent surge in popularity across the US, the current literature lacks evidence on the safety profile of combined facial feminization procedures. Read More

Three-Stage Paramedian Forehead Flap Reconstruction of the Nose Using the Combination of Composite Septal Pivot Flap with The Turbinate Flap and L-Septal Cartilaginous Graft - a Case Report.

Acta Chir Plast 2021 ;63(1):6-13

Nasal basal cell carcinomas are the most common malignant tumors of the facial skin, which predilectively affect areas exposed to sunlight, including the nasal area. After their radical removal, there is a variable complex defect of the affected area (defect of all 3 layers of the nose) or even a composite defect (it also occupies the adjacent soft tissues around the nose), which are usually used to reconstruct this area. A 73-year-old female patient with recurrent infiltrative basal cell carcinoma of the left nasal ala underwent four re-excisions before histologically verified free margins without the presence of the tumor.

Clinical integration of fast Raman spectroscopy for Mohs micrographic surgery of basal cell carcinoma.

Biomed Opt Express 2021 Apr 11;12(4):2015-2026. Epub 2021 Mar 11.

School of Physics and Astronomy, University of Nottingham, University Park, Nottingham, NG7 2RD, United Kingdom.

We present the first clinical integration of a prototype device based on integrated auto-fluorescence imaging and Raman spectroscopy (Fast Raman device) for intra-operative assessment of surgical margins during Mohs micrographic surgery of basal cell carcinoma (BCC). Fresh skin specimens from 112 patients were used to optimise the tissue pre-processing and the Fast Raman algorithms to enable an analysis of complete Mohs layers within 30 minutes. The optimisation allowed >95% of the resection surface area to be investigated (including the deep and epidermal margins). Read More

A modified method for upper eyelid reconstruction with innervated orbicularis oculi myocutaneous flaps and lower lip mucosal grafts.

JPRAS Open 2021 Jun 24;28:131-139. Epub 2021 Mar 24.

Department of Plastic Surgery, National Hospital Organization Osaka National Hospital, Osaka, Japan.

Background: Numerous reports have described methods for repairing full-thickness upper eyelid defects using lower eyelid tissue. To avoid sacrificing the lower eyelid and thereby prevent lower eyelid sagging or dysfunction, we used innervated orbicularis oculi myocutaneous flaps harvested from the upper eyelid for upper eyelid reconstruction.

Methods: We modified a method reported by Moschella and Cordova for repairing full-thickness upper eyelid defects using innervated bipedicled orbicularis oculi myocutaneous flaps mobilized from the upper eyelid and labial mucosal grafts. Read More

Department of Plastic and Reconstructive Surgery, Shanghai Ninth People's Hospital, Shanghai Jiao Tong University, School of Medicine, Shanghai, China.

Midface reconstruction is challenging because the structures and deformities involved are complicated. In this study, we present a strategy for integrally reconstructing nasal and midface defects, including hair-bearing defects, using extended forehead-expanded flaps. From 2015 to 2018, a total of 22 patients with midface defects underwent reconstruction with extended forehead-expanded flaps. Read More

The Rhino-Lip-Lifting: A Novel Proposal for Midface Profileplasty Performed as a Single Surgical Procedure.

Facial Plast Surg 2021 Jun 8;37(3):340-347. Epub 2021 Apr 8.

Department of Facial Plastic Surgery, Rigeneralab Center for Regenerative Medicine, Torino, Italy.

As facial aging occurs, aesthetic changes of the nasal tip and the senile upper lip include tip ptosis, increase in skin length, loss of vermillion height and Cupid's bow, and vertical wrinkles.Regardless of the rejuvenation procedure, the lips are not to be considered as a single anatomical entity, instead they should be placed in a strong correlation with the nose. The aim of this study is therefore to demonstrate the effectiveness of the association of primary closed rhinoplasty together with indirect subnasal lip-lifting technique. Read More

Nasal and Oral Subunits Reconstruction of Localized Scleroderma Deformities.

J Craniofac Surg 2021 Feb 18. Epub 2021 Feb 18.

Department of Plastic and Burn Surgery, West China Hospital, Sichuan University, Chengdu, Sichuan, China.

Abstract: Localized scleroderma is a rare soft tissue disorder characterized by a thickening of the skin from excessive collagen deposits. For patients with face involved, soft tissue depression and atrophy could cause serious facial contour deformity and adversely affect the patients' quality of social life. However, localized scleroderma cases with delicate facial aesthetic subunits defects were rarely reported to be surgically reconstructed. Read More

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

J Plast Reconstr Aesthet Surg 2020 Dec 14. Epub 2020 Dec 14.

Department of Plastic and Reconstructive Surgery, Ulsan university, College of medicine, Asan medical center, Seoul, Korea. Electronic address:

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. Read More

Gene-specific facial dysmorphism in Axenfeld-Rieger syndrome caused by FOXC1 and PITX2 variants.

Am J Med Genet A 2021 02 24;185(2):434-439. Epub 2020 Nov 24.

Department of Ophthalmology, Flinders University, Flinders Medical Centre, Adelaide, South Australia, Australia.

Axenfeld-Rieger syndrome is a genetic condition characterized by ocular and systemic features and is most commonly caused by variants in the FOXC1 or PITX2 genes. Facial dysmorphism is part of the syndrome but the differences between both genes have never been systematically assessed. Here, 11 facial traits commonly reported in Axenfeld-Rieger syndrome were assessed by five clinical geneticists blinded to the molecular diagnosis. Read More

Subunit Approach to Facelifting and Facial Rejuvenation.

Facial Plast Surg Clin North Am 2020 Aug 6;28(3):253-272. Epub 2020 May 6.

Department of Facial Plastic and Reconstructive Surgery, Center for Advanced Facial Plastic Surgery, 9401 Wilshire Boulevard, Suite 650, Beverly Hills, CA 90212, USA.

Facial analysis techniques traditionally separate the upper, middle, and lower facial thirds as distinct entities without guidance in achieving aesthetic youthfulness. There is now an opportunity to develop better analytical tools and specific algorithms to help create an overall harmony to the face and restore a youthful appearance. Facial anatomic subunits have similar three-dimensional qualities based on underlying anatomic structures, craniofacial skeletal modeling, superficial and deep facial fat compartments, skin thickness, facial muscle activity, and curvature (flat, convex, concave).
