Rintala Flap and Posterior Perichondrial Cutaneous Graft: A Combined Approach for Nasal Tip Reconstruction.

Plast Reconstr Surg Glob Open 2022 May 6;10(5):e4316. Epub 2022 May 6.

Department of Plastic, Reconstructive and Aesthetic Surgery, Geneva University Hospitals, University of Geneva, Geneva, Switzerland.

Nasal tip reconstruction requires a meticulous approach due to the complexity of the nasal anatomy and its aesthetic importance. Many procedures have been described to restore this aesthetic unit, including the paramedian forehead flap, which is one of the workhorse flaps. However, despite excellent final outcomes, this procedure may be refused by patients, due to its temporary conspicuous appearance possibly associated with serious psychological implications, and the need of multiple interventions.

Electrophysiologic Frontalis Muscle Response Following Neuromodulator Injections.

Facial Plast Surg Clin North Am 2022 May;30(2):225-231

Department of Clinical Anatomy, Mayo Clinic College of Medicine and Science, Mayo Clinic, Stabile Building 9-38, 200 First Street, Rochester, MN 55905, USA. Electronic address:

Neuromodulator treatments limit the contractility of the frontalis muscle, resulting in reduced dynamic and static horizontal forehead line formation of the overlying skin. This interventional study investigated the electrophysiologic response (via signal-to-noise [SNR] ratio) and the overlying skin displacement of the frontalis muscle following neuromodulator injections in a total of 11 healthy neuromodulator-naïve volunteers. Relating SNR to the respective skin movement revealed that the higher the SNR, the more vertical the skin displacement is; this remained statistically relevant after gender stratification. Read More

Two Japanese patients with Noonan syndrome-like disorder with loose anagen hair 2.

Am J Med Genet A 2022 Jul 25;188(7):2246-2250. Epub 2022 Mar 25.

Division of Molecular Genetics, Institute for Comprehensive Medical Science, Fujita Health University, Toyoake, Japan.

Noonan syndrome-like disorder with loose anagen hair (NSLH) is a rare disease characterized by typical features of Noonan syndrome with additional findings of relative or absolute macrocephaly, loose anagen hair, and a higher incidence of intellectual disability. NSLH1 is caused by a heterozygous mutation in the SHOC2 gene on chromosome 10q25, and NLSH2 is caused by a heterozygous mutation in the Protein phosphatase one catalytic subunit beta (PPP1CB) gene on chromosome 2p23. Protein phosphatase1 (PP1), encoded by PPP1CB, forms a complex with SHOC2 and dephosphorylates RAFs, which results in activation of the signaling cascade and contribution to Noonan syndrome pathogenesis.

The Anatomy behind Eyebrow Positioning: A Clinical Guide Based on Current Anatomic Concepts.

Plast Reconstr Surg 2022 Apr;149(4):869-879

From the Department of Clinical Anatomy, Mayo Clinic College of Medicine and Science; Division of Dermatology, Women's College Hospital; Revance; Department of Dermatology and Skin Science, University of British Columbia; CH Dermatologia; and Division of Dermatology, University of Toronto.

Background: The position of the eyebrow is known to reflect emotional status and to provide a plethora of nonverbal information. Although the eyebrow has no direct attachment to underlying bone, it is subject to the interplay between the various periorbital muscles, which when acting together, permit important nonverbal cues to be conveyed. Understanding the balance and interplay between these muscles is of crucial importance when targeting the periorbital area with neuromodulators. Read More
