ORAL Stensen’s Duct:
Key to Parotidectomy.
A. M. A. Arch.

75: 138, July,
SURGERY S. W. Ulin, E. W. Erhrlich,
and J. W. Smith.
1957.
The purpose of this paper is to relate the author’s anatomic and clinical experience with the use of Stensen’s duct to gain access to the facial nerve branches and gland and to present a compendium of surgical techniques for parotidectomy. The duct averages 3 mm. in diameter and can be probed intraorally with a lacrimal duct probe. The orifice is well marked, and the duct follows a short, straight course. Traction on Stensen’s duct helps to direct the dissection along the cleavage plane between the parotid gland, the facial nerve, and the underlying masseter muscle. An approach to parotidectomy which utilizes Stensen’s duct is described. T. J.

1957. Bone banks have been established in many institutions to preserve bone. ‘This study was undertaken to determine the most favorable temperature, the most satisfactory media, and the optimum length of time bone may be kept in storage to obtain the most successful clinical result. The author’s conclusions are that bone preserved in titrated blood possesses the longest survival period of osteogenic cells and exhibits the greatest power of proliferation of these cells. A temperature of about 5” C. was the optimum temperature for preservation of osteoblastic activity. Autogenous bone, when used at once, offers the greatest chance for a successful result whenever it is necessary to use a graft of bone. T. J. C.
The Use of Tongue Flaps in Head and Neck Surgery. and Max 11. Pierce. Surgery 41: 745, May, 1957.
John J. Conley, Felix de Amesti,
This article deals with the use of the tongue in closing various surgical wounds of the head and neck, which usually are the result of radical removal of malignant lesions. In resection of a large lesion of the floor of the mouth, mandible, and tongue, the residual portion of the tongue is sutured to the mucous membrane of the ipsilateral cheek. When an immediate graft is done, the tongue can be used to cover as well as nourish the graft. When the lesion is limited to the floor of the mouth and tongue with involvement of the mandible, the primary lesion as well as the contents of the ipsilateral neck are removed by the “pull through” technique.
