[The posterior pharyngeal wall in pharyngo-laryngeal cancer. Spontaneous healing after excision]. / La paroi pharyngée postérieure dans les cancers pharyngo-laryngés. Cicatrisation spontanée après exérèse.

Malignant lesions arising from the posterior pharyngeal wall, or spreading to involve it, present a therapeutic problem in cancer surgery as witnessed by the number of techniques proposed and used. In general, they require longer operating time, sometimes need a double team of surgeons and sometimes specialised training. There is an increased risk of complications. The experience with pharyngoplasty using mucosal or musculo-mucosal flaps, which leave the donor site bare, raised the possibility of partial repair in circular pharyngo-laryngectomy. A myocutaneous flap is sutured in "gutter" fashion anteriorly opposite the posterior pharyngeal wall which in fact consists of the prevertebral aponeurosis laid bare. Repair was not performed in certain partial posterior pharyngectomies. Seven patients underwent surgery using this technique. Four circular pharyngo-laryngectomies, including 2 as second stage procedures were performed. Healing occurred in all cases. No breakdown of sutures occurred. Oral feeding was possible from D12 on average and patients were discharged on D18. Three posterior pharyngectomies, including 1 as a second stage procedure, were performed. Feeding was possible in 2 patients on D15 and discharge on D18. These encouraging results suggest that this reliable, rapid single stage procedure technique should be adopted.

[Primary meningioma of the maxillary sinus. Apropos of a case]. / Méningiome primitif du sinus maxillaire. A propos d'une observation.

A case report concerning a left primary maxillary meningioma is presented. Clinical, conventional radiographic and CT signs are presented. The diagnosis was made after histologic examination of the specimen. The pathogenesis is discussed.

[Ethmoidofrontal osteoma. Therapeutic approaches]. / Ostéomes ethmoïdo-frontaux. Modalités thérapeutiques.

Two patients with ethmoidofrontal osteoma revealed by neurologic complications were treated by radical removal of osteoma by an endocranial approach with cranialization of frontal sinuses. Therapy varies with the localization of these osteomas.

[Lymphatic invasion of cancers of the oral cavity. A diagnostic strategy]. / Envahissement ganglionnaire des cancers de la cavité buccale. Stratégie diagnostique.

The diagnostic of ganglionnary invasion in oral cancer is established throughout the histological investigation practiced during the operation. This histological inquiry has to be rigorous and logical, in conformity with the anatomical particularities of the drainage tubes of the oral mucous. The accurate execution of this diagnostical strategy applied to the ganglionnary invasion improves the prognostic but requires a good logistic support.
