[The transfacial flap in surgery of tumors of the middle and posterior 3d of the face and base of the skull. Its use as a means of approach and reconstruction].
A transfacial approach and the use of a bone flap allows exeresis of large tumors of middle and posterior third of face and of base of skull. The procedure can be used alone or associated with a neurosurgical approach to the lesions. This wide surgical approach increases the possibility of a complete excision under conditions of strict hemostasis. Replacement of the bone flap at the end of surgery restores skeletal reliefs ad integrum with excellent esthetic results. The technique is described in detail and several examples of its use outtined.
[Approach to the pterygomaxillary region by the Lefort I osteotomy].
Approach to the pterygomaxillary fossa under the base of skull, a difficult operation, has been facilitated by the use of a technique derived from the Lefort I osteotomy. Satisfactory access to the fossa and to the posterior-base region is obtained and esthetic or functional sequelae avoided.
[Mucoceles of the maxillary sinus. Diagnostic and therapeutic problems. Apropos of 5 cases].
Five cases of the rarely observed maxillary sinus mucocele are reported, one patient with bilateral lesions presenting primary dilatation of the bronchi. A previous history of surgery or injury to sinuses was obtained in all cases, the diagnosis being confirmed by computed tomography imaging. Recovery is usually complete after the Caldwell-Luc operation. One case with exclusion of the sinus is described and the literature reviewed.
[Diagnostic problems of tuberculoid cervical adenitis. Apropos of 70 cases].
Pathologic criteria in tuberculoid adenitis enable differentiation between follicular adenitis with or without caseous necrosis and that involving suppurative necrosis. The absence of specific etiology is emphasized. Seventy cases of tuberculoid adenitis are analyzed. Of the 62 cases of adenitis labelled tuberculous, bacterial confirmation was obtained in only 22 (35%), suggesting probable diagnosis by excess for the remaining 40 cases. Related bacteriologic problems concern isolation of B.K. of the 3 cases classified as sarcoidosis, it was important to obtain data from broncho-alveolar lavage and serum conversion enzyme assay. Four patients with adenitis were diagnosed as having cat-scratch disease from positive specific intradermal reactions, the probable discovery of the responsible agent thus providing a bacteriologic diagnosis.
[Tumors and vascular malformations of the larynx. Angiographic aspects and therapeutic indications].
Satisfactory results were obtained in a case of laryngeal paraganglioma following surgery preceded by angiography and embolization. Clinical, arteriographic and histologic features of vascular malformations of the larynx are discussed, localized and isolated laryngeal angiomas being distinguished from those classified among cervicofacial angiodysplasias. Laryngeal vascular malformations are all capillarovenous angiomas. Treatment has been facilitated by the availability of arteriography and embolization methods, and consists of injections of a sclerosing agent (such as "ethybloc") together with surgery in some cases.

[Mandibular reconstruction by composite musculocutaneous flap in glossopelvimandibular excisions].
Results of 14 mandibular reconstruction by a composite muscular flap of the pectoralis major and trapezium muscles during widespread glossopelvimandibular excisions are described. The technique employed is outlined, emphasis being placed on the need to observe strict precautions during removal and application of the bone component, to avoid accidental avulsion during reconstruction which could compromise the musculoperiosteal vascularization of the graft. Results are sufficiently encouraging for this type of reconstructive surgery to be proposed in all cases where mandibular repair is necessary after interruption of continuity.
[2 modalities in the embryogenic process of frontonasal cysts and fistulae].
The two principal embryogenic theories, persistence of residual structures remaining after closure of the anterior neuropore and inclusion of epiblastic derivatives in the prenasal space, may be combined, with resulting two embryonic varieties of these malformations. Glabellar cysts, with or without fistulae extending them downwards, and which remaining at superficial level may perforate the true nasal bones. Other fistulae can develop which extend deeply and present variable dilatations with a more or less oblique path upwards depending on the level of their opening into the nose.
