Four new species within the genus , , , , and , are proposed based on a combination of morphological traits, physiological features, and molecular evidences. is characterized by globose sporangiospores, a 1.0- to 3.5-μm-long papillary projection on columellae, and sympodial sporangiophores. is characterized by cylindrical to oval sporangiospores, a 1.0- to 4.5-μm-long bacilliform projection on columellae, and spine-like rhizoids. is characterized by variable sporangiospores, up to 9.5-μm-long clavate projections on columellae, and swollen top of the projection and inflated hyphae. is characterized by cylindrical to oval sporangiospores, a 2.0- to 3.5-μm-long spinous projection on columellae, and as many as eight whorled sporangiophores. Phylogenetic analyses based on sequences of internal transcribed spacer rDNA and D1-D2 domains of LSU rDNA support the novelty of these four species within the . All new species are illustrated, and an identification key to all the known species of in China is included.

Use of a Space Graft in Rhinoplasty.

J Craniofac Surg

October 2024

Department of Medical Cosmetology, People's Hospital of Liangjiang New Area, Chongqing, China.

Background: Construction of the nasal tip strut is an important part of rhinoplasty; the incidence of postoperative complications is closely related to the type of graft and the approach to cartilaginous framework construction.

Objectives: To introduce a supplementary graft to support the cartilaginous framework.

Methods: Forty patients (37 female and 3 male), aged from 18 to 40 years (average 29), received a rhinoplasty using a spacer graft.

Long-Term Nose Evaluation After Treatment of Bilateral Cleft Lip Using the Spina Technique.

J Craniofac Surg

October 2024

Federal University of Paraná (UFPR), Federal University of Paraná (UFPR), Assistance Center for Cleft Lip and Palate (CAIF), Hospital do Trabalhador, SESA PR, Curitiba, Brazil.

Introduction: Bilateral cleft lip (BCL) repair is a challenge due to anatomic and functional distortions, worse than unilateral cleft. With regard to the nose, BCL can result in certain characteristics, such as a short columella, a flattened and widened tip, and horizontally oriented nostrils. Lip and nose treatment is advocated by some surgeons to achieve a better outcome.

An Innovation Technique in East Asia Rhinoplasty.

Aesthetic Plast Surg

August 2024

Department of Plastic and Aesthetic (Burn) Surgery, The Second Xiangya Hospital, Central South University, Changsha, 410011, China.

Article Synopsis
  • This study looks into a new approach to rhinoplasty using an external septa framework, specifically tailored for East Asian patients.
  • The technique involves harvesting costal cartilage to create various grafts that provide support and reshape the nasal structure, while also using different materials for augmentation.
  • Results measured through photos and satisfaction surveys show significant improvements in nasal angles, lengths, and projections after surgery, indicating the efficacy of the external septa framework in enhancing rhinoplasty outcomes.

Intermediate rhinoplasty, the correction of cleft lip nose deformities, is performed between the time of primary and secondary rhinoplasties, which is at ~6 years of age. Although intermediate rhinoplasty reduces psychological stress in school-aged children through improvements in appearance, studies on intermediate rhinoplasty are scarce. Hence, in this study, we aimed to evaluate the long-term outcomes of intermediate rhinoplasty in patients with unilateral cleft lip.
