Postoperative rhinoplasty infection can lead to serious cosmetic deformity, loss of structural integrity to the nose, and functional deficiencies. Understanding the factors contributing to postoperative infection is important. Microbial biofilms and persister cells play an important role in health care-associated infections. The objective of this study is to identify microbial biofilm and persister cells in the nasal soft tissue of patients undergoing revision rhinoplasty. Fourteen patients undergoing rhinoplasty were recruited for this study. Nasal soft tissue was removed during rhinoplasty and preserved in 2% paraformaldehyde/2.5% glutaraldehyde. High-resolution images were then obtained from these nasal soft tissue samples. Three samples were positive for the presence of microbial persister cells or biofilms. All samples came from patients undergoing revision rhinoplasty. These patients had between one to six previous rhinoplasty procedures and one patient had previous injectable nasal filler. Biofilms and persister cells are able to form in nasal soft tissue of revision rhinoplasty patients in the absence of an implant and may contribute to increased postoperative infection risk.

THE SOFT TRIANGLE TENSION GRAFT.
Plast Reconstr Surg
January 2025
Private Practice, Ghavami Plastic Surgery, Beverly Hills, California.
Introduction: Rhinoplasty surgeons often rely on tip grafting in order to add volume in the infratip, mid-tip or supratip areas. The author has developed a novel tip graft, from the repurposed, pliable cephalic margins of the lower lateral cartilage lateral crura. The main purpose of the soft triangle tension graft (STTG) is to control tip tension of the medial crura, buttress the soft triangles and add a small degree of volume to the tip.

Optimizing Closed Approach Preservation Rhinoplasty by Ultrasonic-Assisted Techniques for Enhanced Precision.
Aesthet Surg J
January 2025
Careggi University Hospital, Florence, Italy.
Background: Preservation rhinoplasty, particularly dorsal preservation, has gained prominence with the advent of piezoelectric instruments, which minimize trauma and enhance precision in bone reshaping. This approach presents unique challenges, especially in closed techniques, where spatial limitations complicate the use of piezotomes.
Objectives: To evaluate outcomes of piezo-assisted preservation rhinoplasty using specialized instrumentation to enhance visibility, precision, and postoperative recovery in closed rhinoplasty procedures.
Cervical Subcutaneous Emphysema and Pneumomediastinum Following Revision Septorhinoplasty With Autologous Costal Cartilage Graft: A Case Report.
Cureus

Otolaryngology - Head and Neck Surgery, Ondokuz Mayıs University Faculty of Medicine, Samsun, TUR.
Cervical subcutaneous emphysema and pneumomediastinum without pneumothorax are exceedingly rare complications following rhinoplasty, with limited cases reported in the literature. This report presents a case of revision septorhinoplasty using autologous costal cartilage, where the patient complained of a sore throat 36 hours postoperatively. On physical examination, cervical subcutaneous emphysema was palpated, and radiologic evaluation confirmed both cervical subcutaneous emphysema and pneumomediastinum.

Nasal airway obstruction is a frequent complaint in an otolaryngology clinic and is often multifactorial. Anatomic contributors may include a nasal septal deviation, inferior turbinate hypertrophy, and nasal valve compromise. Septoplasty and inferior turbinate reduction are one of the most common procedures performed by an otolaryngologist.
