- چکیده:
- چکیده انگلیسی: As a generalization of semi-invariant Riemannian submersions, we introduce conformal semi-invariant submersions from almost contact metric manifolds onto Riemannian manifolds and study such submersions from Cosymplectic manifolds onto Riemannian manifolds. Examples of conformal semi-invariant submersions in which structure vector field is vertical are given. We study geometry of foliations determined by distributions involved in definition of conformal anti-invariant submersions. We also study the harmonicity of such submersions and find necessary and sufficient conditions for the distributions to be totally geodesic.

- چکیده:
- چکیده انگلیسی: Objective: To evaluate the four commonly used incisions for Radical Neck Dissection on the basis of certain defined
parameters. Patients and Methods: The investigators designed and implemented a prospective comparative study
composed of patients with oral squamous cell carcinoma. The predictor variable was time taken to raise and close the
flaps, accessibility to the neck lymph nodes, injury to vital structures and scar cosmesis followed up to a period of three
months. Descriptive statistics were computed. Results: The sample was composed of 40 patients grouped as follows:
Macfee Incision (=10 patients), Modified Macfee Incision (=10 patients), Modified Schobinger Incision (=10 patients)
and Reverse Hockey Stick Incision (=10 patients). Group A, consisiting of the patients with Macfee Incision, took the
least time to close among all the groups ( Mean= 32.60 minutes) while Group C (patients with Modified Schobinger
Incision) required the most time for closure ( Mean= 51.90 minutes). The Modified Schobinger Incision provided best
exposure to neck node levels. The Macfee Incision was found to have the best scar cosmesis among the four incisions.
Conclusion: The results of this study suggest that Modified Schobinger Incision is the preferred incision for adequate
access to neck lymphatics while Macfee Incision was found to provide the best scar cosmesis.- انتشار مقاله: 04-05-1397
