“…Our previous biomechanics study [ 43 ] analyzed the contact behavior of a nasal stent that was deployed to the ES cavity and showed that there was a significant rise of contact stress on the inside of the ES and a part of the stent material has caused permanent plastic deformation possibly due to mismatch between the stent and nasal cavity. If the shape of the implant deviates too much from the shape of the ES, excessive stress can occur and the ES can become loose [ 43 ]. The design of a commercial stent should ensure optimal stent-ES contact in the ES cavity.…”

Background The ethmoid sinus (ES) is a three-dimensional (3D) complex structure, a clear understanding of the ES anatomy is helpful to plan intranasal surgery. However, most prior studies use 2D measurements, which may not accurately depict the 3D structure. The current study measured the gender differences in ES morphology based on 3D reconstruction of computed tomography (CT) images. Methods The 3D models were reconstructed using CT images. Twenty-one males and 15 females were enrolled in the study. The ES dimensions, including width, height and aspect ratio (AR) of each cutting-plane section, were measured at 10% increments along with the anteroposterior axis of the ES. The gender differences in the above parameters were further evaluated by an independent t-test. Results The width of the ES for males is 12.0 ± 2.1 mm, which was significantly greater than that in females (10.0 ± 2.1 mm). The average height for males is 18.4 ± 3.5 mm, and 18.2 ± 3.4 mm for females. The AR of female (male) is around 0.56 (0.63) for the anterior ES and 0.66 (0.75) for the posterior. There are significant differences between genders in the parameters of width and AR (p < 0.05). Conclusion This study found that the aspect ratio greatly varies along the length of ES, indicating that the cross-section of the ES in the anterior is closer to an elliptical shape and turns closer to a circular shape near its posterior. There is a significant difference between genders in width and aspect ratio. The results would be helpful to know the complex anatomic details of the ethmoid sinus.

“…One of the most important devices are drug delivering nasal sinus stents, which not only reinforces and supports sinuses after endoscopic sinus surgery, but also delivers drugs significantly lowering the recovery time and increase patients’ well-being. 48 Other emerging naturally-derived appliances are based on alginates (Algoderm ® ), 49 gelatin (Cutanplast ® ) 50 or carboxymethylcellulose (CMC) (Prolaryn ® ) 51 and used for variety of applications, including wound healing or vocal fold medialization. Other interesting field of sustainable polymers usage is tissue engineering, but despite numerous literature examples reporting successes in ENT field, the full potential of 3D bioprinting method essential to personalize the engineered tissues has yet to be realized.…”

Polymers from Renewable Resources

The ongoing climate changes, high air and noise pollution have significant impact on humans’ health. This influence is especially visible in otolaryngology, which focuses on respiratory and hearing systems disfunctions. However, even though surgeries are done in response to diseases related to climate changes, they also have a negative impact on the environment, mostly connected with the inherence of single-use fossil fuel derived polymers. This leads to a self-perpetuating emission of greenhouse gases, as human beings developed a lot of synthetic materials to combat climate change derived dysfunctions, which itself endangers human health in a chaotic circular chain. Mitigating issues arising from using synthetic plastics would be possible by imparting biodegradable polymers from renewable resources. Nowadays, sustainable polymers are adopted mostly in emerging fields of medicine, such as 3D printing, tissue engineering of drug delivery systems. Sustainable polymers are particularly useful in otolaryngology, e.g., in the form of nasal drug eluting stents or bone substitutions. Nevertheless, some limitations in wider usage of renewable polymers in surgery should also be underlined, mainly related to lack of legislation, clinical considerations, and also inadequate materials’ circularity. Herein we briefly overviewed commonly used polymers in general surgery and otolaryngology, defined the trends in sustainable polymer usage in these fields, and highlighted the limitations in renewable polymers applications together with possible solutions. What this short review emphasizes, is that the significant increase in interest and demand for sustainable solutions will revolutionize the future of clinical treatments, where contribution to climate change and waste management will be centered in decision making protocols.

“…They have demonstrated potential efficacy in nasal packing, improving wound healing, and patient-reported outcomes [9]. The biomaterials can even be fabricated into self-expanding sinus stents used in functional endoscopic sinus surgery [10]. Materials can also be utilized in the application of 3D bioprinting technologies in reconstruction and tissue engineering for head and neck surgery [11].…”

This retrospective study compared the effectiveness of different materials used in Uvulopalatopharyngoplasty (UPPP) for snoring or obstructive sleep apnea treatment, focusing on the impact on bleeding control, pain control, and healing ability. The study population comprised 213 patients who underwent UPPP at Wan-Fang Hospital between July 2018 and October 2022 divided into four groups based on the postoperative material used: No Material Use Group, Tissue Glue Group, Platelet-Rich Plasma (PRP) Group, and Polyglycolic Acid (PGA) Sheet Group. Results showed significant differences in operation time and intraoperative bleeding amount among the groups, with the Tissue Glue Group demonstrating the shortest operation time. While no significant differences in postoperative pain at 24 h were observed, PRP and PGA Sheet groups exhibited lower average pain scores in cases with higher pain levels. Postoperative complications and emergency room visits due to pain or bleeding varied among the groups, with the No Material Use Group having the highest incidence, although no statistical significance was achieved. This study provides insights into the potential benefits of using advanced materials in UPPP, guiding future research and clinical practice to improve patient care and outcomes.
