Parathyroid microautotransplantation and the viscerovertebral angle.

Conservation of physiologic values of circulating parathormone is a surgical objective in those instances in which a hyperfunctional parathyroid state exists as well as in those instances in which cervical evisceration employed as an ablative measure for the management of neoplastic disease threatens to impose postoperative tetany. Because the parathyroid glands may vary in number and in anatomic sites, a predictable and reproducible surgical approach that permits the operator an avenue of access to these structures is used. The viscerovertebral angle provides a surgical modality which facilitates the operative effort. The method has been applied in more than 70 patients.

Surgical palatomaxilloschisis: an avenue to the pterygomaxillary space.

The pterygomaxillary space (PMS) is a potential reservoir for expansion of the neoplasms originating in the epipharynx. Palatotomic and mandibulotomic approaches to this secluded site have been reported. The advantages of surgical palatomaxilloschisis are twofold. First, the exposure of the operative field is panoramic. Second, the carotid arterial system is identifiable prior to surgical intervention. The triangular pterygomaxillary recess is bounded superiorly by the greater wing of the sphenoid, posteriorly by the pterygoid process and anteriorly by the dorsal convexity of the posterior wall of the maxilla. Ascending laterally to the PMS in its route to penetrate the temporal bone is the internal carotid artery. In particular, juvenile angiofibromas which originate in the epipharynx may in their growth encroach upon the bounds of the PMS. The surgical objective is not only to extirpate the neoplasm but also to safeguard the carotid arterial system which may be displaced by the new growth and thereby become a surgical hazard. A clinical experience illustrates the applicability of this approach.

Total extrathoracic neoesophageal construction by combined cutaneous and myoepithelial flaps.

A previously unreported low-morbidity staged procedure for the extrathoracic construction of neoesophagus employing a combination of skin-lined cutaneous an myoepithelial flaps is proposed as an adjunct to, or as a primary method for, the surgeon confronted with the problem of restoring the continuity of the food passage, which follows thoracic esophageal resection. The case report does not mean to imply or convey the impression that this procedure is a first-line method. Rather, it is offered as an alternative or adjunct in those instances in which customary and accepted techniques cannot be executed, as in this presentation.
