Summary
The longus capitis muscle (LCM) flap offers a viable solution for soft palate (SP) reconstruction after cancer surgery. This local flap provides functional recovery with minimal donor site issues.
Area of Science:
- Head and Neck Surgery
- Surgical Oncology
- Reconstructive Surgery
Background:
- Soft palate reconstruction presents significant challenges in head and neck surgery.
- The longus capitis muscle (LCM) is a deep neck flexor with suitable characteristics for local flap reconstruction.
Purpose of the Study:
- To evaluate the efficacy of the superiorly based longus capitis muscle (LCM) flap for soft palate (SP) reconstruction in patients with tonsil squamous cell carcinoma.
Main Methods:
- A retrospective review of 3 patients with T2-T4 tonsil squamous cell carcinoma undergoing SP resection and LCM flap reconstruction.
- Patients underwent transoral resection, followed by reconstruction with a superiorly based LCM flap.
- Adjuvant therapy was administered as indicated.
Main Results:
- All 3 patients had full-thickness SP defects of at least 50% after resection.
- Within 3 to 8 months post-reconstruction, all patients achieved a full oral diet.
- No cases of dysphagia, nasal regurgitation, or velopharyngeal insufficiency were reported.
Conclusions:
- The superiorly based LCM flap is a functionally acceptable option for reconstructing significant soft palate defects.
- This reconstructive technique offers minimal donor site morbidity for select patients.

01:10Reconstruction of Signal using Interpolation
707
Signal processing techniques are essential for accurately converting continuous signals to digital formats and vice versa. When a continuous signal is sampled with a period T, the resulting sampled signal exhibits replicas of the original spectrum in the frequency domain, spaced at intervals equal to the sampling frequency. To handle this sampled signal, a zero-order hold method can be applied, which creates a piecewise constant signal by retaining each sample's value until the next...

01:07Electron Microscope Tomography and Single-particle Reconstruction
2.8K
Transmission electron microscopy (TEM) can be used to determine the 3D structure of biological samples with the help of techniques such as electron microscope tomography and single-particle reconstruction. While single-particle reconstruction can examine macromolecules and macromolecular complexes in vitro conditions only, tomography permits the study of cell components or small cells in vivo.

02:35What is Evolutionary History?
43.0K
Scientists record evolutionary history by analyzing fossil, morphological, and genetic data. The fossil record documents the history of life on Earth and provides evidence for evolution. However, both fossil and living organisms offer evidence that outlines Earth’s evolutionary history.

02:18Network Covalent Solids
16.1K
Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

02:56The Fossil Record
27.2K
The fossil record documents only a small fraction of all organisms that have ever inhabited Earth. Fossilization is a rare process, and most organisms never become fossils. Moreover, the fossil record only exhibits fossils that have been discovered. Nevertheless, sedimentary rock fossils of long-lived, abundant, hard-bodied organisms dominate the fossil record. These fossils offer valuable information, such as an organism's physical form, behavior, and age. Studying the fossil record helps...

02:54Molecular and Ionic Solids
20.0K
Crystalline solids are divided into four types: molecular, ionic, metallic, and covalent network based on the type of constituent units and their interparticle interactions.
Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...
