Summary
Reconstructing total maxillary defects (Brown class 2b) is complex. A modified technique using a vascularised fibular flap and coronoid temporalis pedicle flap offers improved aesthetic and functional outcomes for orbital reconstruction.
Area of Science:
- Oral and Maxillofacial Surgery
- Plastic Surgery
- Reconstructive Surgery
Background:
- Total maxillary defects with orbital retention (Brown class 2b) present significant reconstructive challenges.
- Traditional methods using solely vascularised fibular flaps for orbital floor, zygoma, and maxilla reconstruction are technically demanding.
- Titanium mesh for orbital floor reconstruction carries risks of discomfort and infection.
Purpose of the Study:
- To present a modified surgical technique for reconstructing total maxillary defects with orbital retention.
- To evaluate the aesthetic and functional outcomes of this novel approach.
Main Methods:
- A combined technique utilizing a vascularised fibular flap and a coronoid temporalis pedicle flap was employed.
- The procedure was performed on two patients with total maxillary defects (Brown class 2b).
Main Results:
- The modified technique provided satisfactory aesthetic and functional results in both patients.
- The approach ensured adequate tissue for infraorbital skin defects and sufficient pedicle length.
- The technique required only a single fibular osteotomy, simplifying the procedure.
Conclusions:
- This modified technique offers a viable and effective solution for complex maxillary reconstructions.
- The combination of vascularised fibular flap and coronoid temporalis pedicle flap addresses limitations of traditional methods.
- This represents a novel approach to managing total maxillary defects with orbital retention.

01:23Lumber Defects

Lumber defects, which can affect both the appearance and structural integrity of wood, include a variety of growth and manufacturing flaws. Growth defects such as knots and knotholes occur where branches were once attached to the tree trunk, with knotholes forming when these knots fall out. Other natural defects include decay and insect damage, which compromise the wood's strength and durability.

01:10Reconstruction of Signal using Interpolation

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...

Total voids in concrete encompass gel water volume, capillary pores, and entrapped air. Gel water (retained within the cement hydration products) and physically entrapped or adsorbed water are significant for the hydration process. For complete hydration, it's estimated that the space needed for the products of a cubic centimeter of cement doubles. Capillary pores constitute the unoccupied space within the hydrated cement paste, with their size largely influenced by the water-to-cement...

A standard box and whisker plot informs us about the spread of the data in a given sample. One can identify the minimum value, maximum value, first quartile value, second quartile or median value, and third quartile.
However, the box plot does not tell the reader about outliers - values that lie far from the center of the data. We can modify the standard box and whisker plot to identify the outliers and visualize the actual spread of the data in a sample.
Initially, we calculate the adjusted...

01:05Total Internal Reflection Fluorescence Microscopy
13.5K
Total internal reflection fluorescence microscopy or TIRF is an advanced microscopic technique used to visualize fluorophores in samples close to a solid surface with a higher refractive index, such as a glass coverslip. TIRF only allows fluorophores in proximity to the solid surface to be excited. When light from a medium with a lower refractive index (such as air) hits the glass coverslip at a critical angle, the light undergoes total internal reflection stead of passing through the glass.
