The intraoperative anatomy, the technical essentials for vascular pedicle protection and submandibular lymph nodes treatment, and the rational design of flap incisions were analyzed and described.ResultsMost patients (21/23, 91.3%), comprising 19 males and 4 females with a mean age of 59 years, recovered completely from the application of SIFs in the repair and reconstruction of head and neck tumors; Only 2 patients experienced partial flap necrosis, which resolved following a local dressing change. The predominant donor site complication was transitory paralysis of the mandibular marginal branch of the facial nerve (MMBFN) (3/23, 13.0%), and the donor site was closed in one stage without skin grafting. The hair growth on skin flaps was not an issue for male patients requiring postoperative radiotherapy.ConclusionsSIF is a viable choice for correcting abnormalities of the head and neck tumor with the convenience of flap cutting and the effectiveness of the repair.

All patients had undergone surgical resection, intralesional injection of triamcinolone acetonide (TAC), and the application of an individual pressure splint.

The excitation of LSPR confines incident light near the surface of plasmonic nanocrystals and amplifies the local electric field. Moreover, the frequency of LSPR is highly tunable in the visible and near-IR regions, allowing plasmonic nanocrystals to efficiently absorb and scatter light across the solar spectrum. Such a property makes plasmonic nanocrystals promising candidates for utilizing solar irradiation to drive chemical reactions, a process known as plasmonic photocatalysis. Upon the resonant excitation of LSPR, energetic hot electrons and holes are generated via the nonradiative decay of LSPR in plasmonic nanocrystals. Those hot carriers can be transferred into the molecular orbitals of adsorbed reactants, enabling chemical transformations at the surface of nanocrystals. However, during the charge transport within plasmonic nanocrystals, hot carriers rapidly relax into lower-energy states. As a result, their energy is often dissipated to the lattice as heat, increasing the local temperature rather than directly contributing to chemical reactions─posing a fundamental challenge to achieving efficient solar-to-chemical energy conversion using plasmonic nanocrystals.&lt;/p&gt;&lt;p &gt;To address this challenge, our group has developed multiple strategies to control the lifetime, energy level, and spatial distribution of plasmon-generated hot carriers to enhance the photocatalytic activity of Au nanocrystals. To extend the lifetime of hot carriers to match the slow kinetics of chemical reactions, Au nanocrystals were attached to an n-type semiconductor to form a heterojunction. This structure was found to prolong the lifetime of hot electrons through efficient spatial separation of hot electrons and holes, facilitated by the Schottky barrier at the metal/semiconductor interface. In parallel, decorating Au nanocrystals with redox-active molecules was shown to extend the lifetime of hot holes. Those hot holes were chemically stabilized and trapped within the bonds of the redox-active species, allowing them to participate in subsequent chemical reactions. Furthermore, a direct correlation between the activity of hot-electron-driven reduction reactions and the size of plasmonic nanocrystals, as well as between hot-hole-driven oxidation reactions and the wavelength of incident light, was established. Those observations demonstrated that energy levels of hot carriers involved in chemical reactions can be manipulated by tuning the size of nanocrystals and the wavelength of light. Moreover, positively charged molecules with facet-selective adsorption on Au nanocrystals were found to stabilize the plasmon-generated hot electrons, enabling control over the spatial distribution of hot carriers.

We analyzed the pure tone audiometry (PTA) and air-bone gap (ABG) data as continuous variables, and the success rate was analyzed as a dichotomous variable.ResultsForty-four studies, including 4582 patients, were eligible. The cartilage graft overall morphologic success rate was higher than that of the TF grafts (<i>P</i> < .001). In the palisade (<i>P</i> < .004) and island grafts (<i>P</i> < .001) subgroups, the analysis was significantly different. However, there was no significant difference in the inlay butterfly grafts subgroup. For hearing outcomes, the analysis revealed that TF grafts had a smaller mean post-operative ABG (<i>P</i> = .009). However, the subgroup analysis showed no significant difference in the mean post-operative ABG. For PTA, there was no significant difference in hearing improvement. However, the palisade cartilage graft subgroup resulted in a better hearing outcome than the TF graft subgroup in terms of the mean post-operative PTA (<i>P</i> = .007).

Both cartilage and TF tympanoplasty provided similar improvements in hearing outcome, while TF grafts generated a better outcome in post-operative ABG and palisade cartilage grafts in post-operative PTA.
