Comprehensive Diagnosis and Planning for the Difficult Rhinoplasty Patient: Applications in Ultrasonography and Treatment of the Soft-Tissue Envelope

AbstractRhinoplasty is one of the most complicated operations that a plastic surgeon will encounter. In the early history of rhinoplasty, operations were done with a closed approach, and the structures were shrouded in mystery while surgeons relied on surface aesthetics for diagnosis and treatment. Finally, with the advent of the extended open approach, power tools, and piezosurgery, the whole bony pyramid can be directly visualized, shaped, and sculpted. Osteotomies can be done under direct vision with high precision. Using this approach, every part of the osseocartilaginous vault and nasal tip can now be directly observed, diagnosed, and surgically treated. However, this only occurs once the patient is in the operating room. This article will detail the diagnosis and treatment of the difficult soft-tissue envelope of the nose. It will also describe the use of ultrasonography for preoperative planning as well as postoperatively for diagnosis and treatment during the healing period and for planning possible revision and secondary surgery.

Preservation Technique

AbstractPreservation rhinoplasty is a new way to reshape the nose by preserving the dorsum, nasal ligaments, soft tissue envelope, and muscles. This new concept provides the opportunity to achieve a more natural aesthetic and functional result. To achieve a good aesthetic and functional outcome while maintaining surgical safety, knowledge of the relevant anatomy is key. This is especially true for the preservation rhinoplasty technique, where a firm grasp of the anatomy of the nasal soft tissue and bony–cartilaginous framework is critical. The preservation technique is made more accessible by the open approach, which provides an opportunity for the deformity to be clearly visualized from the tip of the nose and the dorsum. Furthermore, tip plasty is easier to perform under direct vision, which is an advantage of the open approach. The goal of this article is therefore to make clear all the important anatomical structures and their relevance to the surgical steps taken when performing the open preservation rhinoplasty technique.

Bone Anchorage

Monolateral external fixation is a system for the stabilization, reduction, and manipulation of bone segments by means of bone anchorage consisting of pins fastened to an external frame. Monolateral external fixators in their various forms have the advantage that they allow the use of half-pins (bicortical pins that do not penetrate both sides of the soft tissue envelope), thereby avoiding major damage to the neurovascular structures contralateral to the insertion point. The simple structure of monolateral systems permits rapid application and simplified preoperative planning, both of which are features particularly appreciated in traumatology.

ABSTRACT Cephalometric analysis for diagnosis and treatment planning of orthodontic patients is essentially a measurement system designed to describe relationships between various parts of the skeletal, dental and soft tissue elements of craniofacial complex. As the linear and angular measurements vary between males and females and with the age, one of our objectives was to compare the statistical difference between males and females. The study was performed using sample size of 60 cephalometric radiographs of 30 males and 30 females. The samples were selected on the basis of class I dental relationship with clinically acceptable profile, no history of orthodontic treatment and of Jaipur (Rajasthan) population.

Electron Microscopes

By 1940, a half dozen or so commercial or home-built transmission electron microscopes were in use for studies of the ultrastructure of matter. These operated at 30-60 kV and most pioneering microscopists were preoccupied with their search for electron transparent substrates to support dispersions of particulates or bacteria for TEM examination and did not contemplate studies of bulk materials. Metallurgist H. Mahl and other physical scientists, accustomed to examining etched, deformed or machined specimens by reflected light in the optical microscope, were also highly motivated to capitalize on the superior resolution of the electron microscope. Mahl originated several methods of preparing thin oxide or lacquer impressions of surfaces that were transparent in his 50 kV TEM. The utility of replication was recognized immediately and many variations on the theme, including two-step negative-positive replicas, soon appeared. Intense development of replica techniques slowed after 1955 but important advances still occur. The availability of 100 kV instruments, advent of thin film methods for metals and ceramics and microtoming of thin sections for biological specimens largely eliminated any need to resort to replicas.
