A 67-year-old Caucasian male presented with severe contraction of socket lining 8 years after enucleation, dermis fat graft and successful ocular prosthesis fitting. Following two failed attempts at using amniotic membrane grafts to reform the socket lining, a total socket reconstruction was attempted using a novel nasal turbinate mucosal graft technique. This was performed in a staged fashion with lower fornix reconstruction followed by upper fornix reconstruction 3 months later. The patient was stable at 12 months review, with a satisfactory cosmetic outcome. Nasal turbinate mucosa was used as it was surgically accessible, provided natural socket lubrication due to its mucosal surface, and avoided oral mucosa and its associated morbidity. This case report suggests that nasal turbinate mucosa is a suitable autologous grafting material for total socket reconstruction in contracted anophthalmic sockets.

The transmission bottleneck, defined as the number of viruses shed from one host to infect another, is an important determinant of the rate of virus evolution and the level of immunity required to protect against virus transmission. Despite its importance, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission bottleneck remains poorly characterized. We adapted a SARS-CoV-2 reverse genetics system to generate a pool of >200 isogenic SARS-CoV-2 viruses harboring specific 6-nucleotide barcodes, infected donor hamsters with this pool, and exposed contact hamsters to paired infected donors, varying the duration and route of exposure.

Nasal adhesions, or synechiae, commonly occur following surgical procedures, resulting in nasal airway obstruction and patient discomfort. While various packing materials are available to prevent adhesion formation post-surgery, there is limited guidance on effectively dividing existing adhesions and determining the optimal packing materials to maintain separation afterward. We treated a 59-year-old man with severe adhesions in the anterior nasal cavity.

Background: The septal swell body (SSB), a distinct anatomical structure located in the anterior nasal septum, has been recognized as a significant contributor to nasal obstruction, impacting airflow dynamics and nasal resistance. This meta-analysis evaluated the impact of septal swell body volume reduction (SSBVR).
Methods: A systematic review of studies from PubMed, SCOPUS, Embase, Web of Science, and Cochrane databases was conducted through October 2024.

Introduction: This study aimed to evaluate the outcome of radiofrequency ablation of the inferior turbinates (RFIT) combined with posterior nasal nerve neurolysis (RPN3) in comparison with RFIT alone in the treatment of patients with chronic rhinitis unresponsive to pharmacological therapy.
Methods: A retrospective cohort study was conducted on adult and adolescent patients with chronic rhinitis who demonstrated a poor response to medication. Patients with a total 24-hour reflective total nasal symptom score (rTNSS) of ≧5, rhinorrhea score of ≧2, and congestion score of ≧2 were included.

Dry powders offer the potential to increase stability and reduce cold-chain requirements associated with the distribution of vaccines and other thermally sensitive products. The Alberta Idealized Nasal Inlet (AINI) is a representative geometry for characterization of nasal products that may prove useful in examining intranasal delivery of powders. Spray-dried trehalose powders were loaded at 10, 20, and 40 mg doses into active single-dose devices.
