In modern rhinoplasty, two foundational approaches for modifying the nasal dorsum developed in the beginning of the 20th century: -preservation and structural techniques. Preservation involves -maintaining the nasal structure by displacing the hump into the nose without directly resecting it. This method preserves structural integrity and avoids nasal valve collapse but can lead to mid-vault widening and hump recurrence. In contrast, structural rhinoplasty entails -directly removing bone and cartilage, offering precise hump reduction but risks over-resection, dorsal irregularities, and mid-vault collapse. The patient's individual anatomical factors guide the practitioner in choosing the most suitable -approach for correcting the nasal dorsum.

To observe the effects of different repair methods in the defects after Mohs surgical excision of malignant nasal tumors. Twenty-two cases of external nasal malignant tumor surgery from January 2021 to May 2024 were selected as the research. The tumors were resected using Mohs surgical technique, and the defects were repaired using forehead axial flap, bipedicle flap, nasolabial flap, free full-thickness skin graft from the groin, forehead axial flap, facial kite flap, and composite flap of earlobe cartilage and perichond.

Background In acne-prone skin, the loss of homeostasis leads to aberrant epithelial differentiation, promoting the formation of microcomedones. The maintenance of sebaceous stem cell homeostasis has emerged as a new therapeutic target in acne management. Objective: The aim of this study is to evaluate the efficacy, tolerability, and safety of a topical formulation combining retinaldehyde, glycolic acid, and Silybum marianum fruit extract for the treatment of acne vulgaris.

In our previous study, we generated a membrane-type progesterone receptor γ (paqr5b) knockout zebrafish line. Knocking out paqr5b by genome editing resulted in the loss of neurons in the olfactory rosette (OR). These findings indicated that Paqr5b plays an essential role in the formation of olfactory neurons.

Background: Intramedullary spinal cord melanocytic neoplasm (IMSCMN) with hemorrhagic features is rare, and it is even rarer in children. The authors present a pediatric case of an IMSCMN involving the thoracic segment of the spinal cord.
Observations: An 11-year-old previously healthy girl experienced intermittent low back pain for 5 months, followed by left foot drop, limb weakness, and abnormal gait.
