A patient with white sponge nevus involving the buccal mucosa, labial mucosa, and soft palate is reported. The salient clinical and histological features of the disease were discussed. This diagnosis should be considered when bilateral white lesions of buccal mucosa are encountered.

Anatomy of the Corrugator Muscle
Journal of Craniofacial Surgery, 2017The aim of this article is to systematically review the anatomy and action of the corrugator muscle. PubMed and Scopus were searched using the terms "corrugator" AND "anatomy." Among the 60 full texts from the 145 relevant abstracts, 34 articles without sufficient content were excluded and 4 articles drawn from the reference lists were added. Among the

Quarter-Wave Corrugated Transformer for Broadband Matching of a Corrugated Feed
AT&T Bell Laboratories Technical Journal, 1984This paper describes a broadband technique for obtaining the transformation TE 11 → HE 11 at the input of a corrugated feed. Usually, this transformation is obtained by operating the feed in the vicinity of a frequency, coi, corresponding to one of the zeroes of the input surface reactance since the feed input reflection, ρ t vanishes at ω 1 .

Anatomy of the Corrugator Supercilii Muscle: Part I. Corrugator Topography
Plastic and Reconstructive Surgery, 2007Complete corrugator supercilii muscle resection is important for the surgical treatment of migraine headaches and may help prevent postoperative abnormalities in surgical forehead rejuvenation. Specific topographic analysis of corrugator supercilii muscle dimensions and its detailed association with the supraorbital nerve branching patterns has not ...

Corrugated conical horns with arbitrary corrugation depth
Radio and Electronic Engineer, 1973The form of fields in a conical horn with uniform circumferential corrugations, when the corrugation depth assumes arbitrary values in the interval 0.25 ≦ (h/γo0) ≦ 0.5 is investigated in this paper. Assuming the corrugations to be infinitely thin and sufficiently close-packed, an impedance boundary condition is imposed on the fields in the axial ...

Analysis of propagation in corrugated waveguides of arbitrary corrugation profile
IEEE Antennas and Propagation Society International Symposium. 1999 Digest. Held in conjunction with: USNC/URSI National Radio Science Meeting (Cat. No.99CH37010), 2003The propagation constants of Floquet modes in corrugated circular waveguides with continuous corrugation profiles were determined from a formulation leading to a canonical matrix eigenvalue equation. The approach is validated by comparison to available data for the dispersion relation of TM/sub 0(n)/ modes in a sinusoidally corrugated waveguide ...

Properties of cutoff corrugated surfaces for corrugated horn design
IEEE Transactions on Antennas and Propagation, 1974Corrugated horns involve a junction between the corrugated surface and a conducting groundplane. Proper horn design requires an understanding of the electromagnetic properties of the corrugated surface and this junction. An integral equation solution has been used to study the influence of corrugation density and tooth thickness on the power loss ...

A corrugated horn antenna using V-shape corrugations
IEEE Transactions on Antennas and Propagation, 1975Corrugated horns use corrugations on the E -plane walls that are operating in the cutoff condition. In this paper, attention is focussed on replacing the rectangular shaped corrugation with a V-shaped corrugation. The properties of the V corrugations are obtained using an integral equation solution; the results of the computational studies indicate ...
