Does Unilateral Temporomandibular Total Joint Reconstruction Result in Contralateral Joint Pain and Dysfunction?

Purpose: The purpose of this study was to evaluate patients requiring unilateral total temporomandibular joint (TMJ) reconstruction and the risk for development of postsurgical contralateral TMJ pain and dysfunction over time requiring subsequent contralateral total joint reconstruction. Long-term subjective and objective outcomes of unilateral TMJ reconstruction also were evaluated.

Materials And Methods: Seventy patients underwent unilateral total joint reconstruction using a patient-fitted total joint prosthesis from a single private practice from 1990 through 2012.

Successful reconstruction of nongrowing hemifacial microsomia patients with unilateral temporomandibular joint total joint prosthesis and orthognathic surgery.

Purpose: Traditionally, patients with hemifacial microsomia (HFM) and significant ipsilateral hypoplasia or absence of the condyle and ramus undergo reconstruction on the ipsilateral side with autogenous tissues such as rib grafts, often with compromised results. This study analyzed the surgical treatment outcomes of nongrowing patients with HFM and reconstruction of the ipsilateral temporomandibular joint (TMJ) and advancement of the mandible with a patient-fitted TMJ total joint prosthesis (TMJ Concepts, Inc, Ventura, CA), a contralateral mandibular ramus sagittal split osteotomy, and maxillary osteotomies performed in 1 operation.

Patients And Methods: All nongrowing patients with HFM treated with this surgical protocol from 1997 to 2010 in a single private practice were included in this study and subjectively evaluated before surgery and at the longest postsurgical follow-up for pain, diet, jaw function, and disability using a visual numerical scale (0 to 10).

Inhibition of oral carcinogenesis by citrus flavonoids.

Six citrus flavonoids were tested for antineoplastic activity. The hamster cheek pouch model was utilized, and the solutions of the flavonoids (2.0-2.

Vanadium-catalyzed selenide oxidation with in situ[2,3] sigmatropic rearrangement (SOS reaction): scope and asymmetric applications.

A vanadium-catalyzed method for the oxidation of prochiral aryl, allylic selenides with tandem [2,3] sigmatropic rearrangement has been developed. This protocol has been screened on a series of substrates to test for its generality and effectiveness. The applicability of this methodology to the synthesis of enantiomerically enriched allylic alcohols has been studied on a series of chiral oxazole-containing systems with a diastereomeric ratio (d.

Synthesis of the ABC ring system of azaspiracid. 1. Effect of D ring truncation on bis-spirocyclization.

[reaction: see text] Synthesis of a spirocyclization precursor with a truncated D ring has been accomplished. Subsequent bis-spirocyclization induced the formation of equal amounts of the natural transoidal 10R,13R bis-spirocycle and its cisoidal 10R,13S epimer under an apparent thermodynamically controlled process.
