Objective: To evaluate endoscopy for detection of epithelial remnants within the feline tympanic bulla following ventral bulla osteotomy (VBO) and to report the most likely locations within the bulla for epithelial remnants to occur.
Methods: This was a single-center experimental cadaveric study. 10 VBO procedures were performed by 5 board-certified surgeons in 5 feline cadavers.
Why Does an "Avatar Nose" Appear After Dermal Filler Injection? Insights From a Cadaveric Study on the Nasofrontal Ligament.
Dermatol Surg
January 2025
Division in Anatomy and Developmental Biology, Department of Oral Biology, Human Identification Research Institute, BK21 FOUR Project, Yonsei University College of Dentistry, Seodaemun-gu, Seoul, Korea.
Background: Nonsurgical rhinoplasty (NSR) with dermal fillers has gained popularity because of its immediate and visible results, minimal downtime, and long-lasting effects. However, complications such as filler migration can lead to the development of the "Avatar nose," a condition where the nose appears unnaturally wide and bulbous in the nasion area, disrupting facial harmony. This phenomenon is often exacerbated by the presence of a taut nasofrontal ligament, which tethers the periosteum to the dermal layer and influences nasal contour.

The facial and transverse facial arteries supply blood to the superficial structures of the face. Understanding these arterial variations is essential for optimizing surgical planning and outcomes, especially in invasive facial procedures. A 78-year-old male cadaveric dissection documented variations in facial and transverse facial arteries.

Department of Anesthesiology, Ibra Hospital, Ibra, Oman.
Background: It is very well known that the supraclavicular nerve (SCN) which occupies the inferior part of the superficial cervical plexus basically originates from the ventral rami of C2-C4, then travels caudally into the investing layer of the deep cervical fascia (IL-DCF) alternatively termed the "prevertebral fascia."
Methods: This cadaveric study (a total of 6 soft-embalmed cadavers and bilateral dissections, i.e.
Characterization of Tip Fold-Over Using Fluoroscopy and Intracochlear Pressure in Cadaver Specimens.
Laryngoscope
December 2024
Department of Otolaryngology, University of Colorado School of Medicine, Aurora, Colorado, U.S.A.
Article Synopsis
- The study examined cochlear implant array malpositioning, particularly focusing on a specific issue called tip fold-over, which can impair speech perception and cause other complications.
- Researchers conducted experiments using cadaveric human heads to measure intracochlear pressure and observe the mechanics of tip fold-over events during the insertion of electrodes.
- Three distinct types of tip fold-overs were identified, with significant pressure changes linked to electrode twisting; this recognition could improve surgical techniques and monitoring during cochlear implant procedures.
