[Reconstructive anterior frontal laryngectomy (author's transl)].

Sliding epiglottoplasty was employed for reconstruction of the glottis after subtotal laryngectomy. Technical aspects are described, and the indications and limitations of this reconstructive partial laryngectomy procedure are discussed from the anatomic and carcinologic points of view. Its advantages include lack of postoperative complications, the very good functional results obtained, and the fact that it can be conducted following radiotherapy and in debilitated patients. It has a limited but definite place among partial laryngectomy procedures.

[The parathyroid risk in thyroidectomy].

The authors report their experience of parathyroid risk in thyroid surgery on the basis of 1 188 thyroidectomies performed between 1973 and 1980. The benign thyroid pathology, the risk is negligeable, approximately 1%, though with the exception of operations for recurrence. In malignant tumour pathology, amongst 98 carcinomas treated by total thyroidectomy and mediastino-recurrent laryngeal lymph node dissection, the authors report an overall percentage of definitive major hypocalcaemia of 22.5%. Routine identification of the parathyroids at the start of the operation, at least on the healthy side, and care not to damage their vascular supply has made it possible to reduce the rate of hypoparathyroidism to 10% in the past two years. A study of anatomical dissection of 200 parathyroid glands with vascular injection is reported in the preamble. Finally, the authors analyse in the literature the results of parathyroid transplant and report their own experience.

[Diagnosis of glomus jugulare tumours (author's transl)].

The present study is based on 16 personal cases and on an analysis of the principal series published since 1968. Clinical investigations aim at detecting lesions of the sensory-motor and XIIth cranial nerves, deafness which indicates invasion of the labyrinth, lesions of central auditory and vestibular pathways and possible associated conditions. Radio-otology is fundamental in revealing alterations of the jugular foramen and above all perhaps, changes in the tympanic bone and in the 3rd segment of the fallopian canal. The most significant sign of invasion is infra-labyrinthic hollowing out on tomographic sections in lateral projection and Guillen's incidence. Angiography and jugulography supply information on the size of the tumour and on its feeding vessels which usually arise from the external carotid artery but also, in advanced forms, from the internal carotid and vertebral arteries. Computerized tomography for the time being has one single major applications : detection of lesions extending to the posterior and middle fossae. Taken together, these investigations should help to classify tumours of the glomus jugulare into : exclusively tympanic, tympano-mastoidal, tumours extending posteriorly and to the petrous bone, and tumours extending intracranially. Such a classification is of paramount importance in deciding on the best surgical approach.

[Prevention and pretherapeutic evaluation of laryngo-tracheal stenosis in adult (author's transl)].

The prevention of laryngo-tracheal stenosis and their etiological factors are the subject of this study. The used material (tube, balloon,...) and the patient could be the principal reason of these etiology, either for intubation or tracheotomy. The pressure in the balloon and the tracheal mucosal puls are developed. The knowledgement of the principal etiologic factors in the constitution of laryngo-tracheal stenosis, make us able to prevent them with efficacity. Finaly, a preoperative evaluation by tomography and endoscopy is establiched.

Management and aesthetic results of support grafts in saddle nose surgery.

To define the surgical management and long-term aesthetic results of patients undergoing rhinoplasty with support graft for saddle nose, 147 patients have been included in this retrospective study. One hundred forty-four autogenous grafts (bone or cartilage) and three processed irradiated bovine cartilage grafts have been used during the period 1980-1997. Two approaches have been employed: open rhinoplasty and endonasal approach. Most of cases have been treated with bony grafts (116 bone graft versus 26 cartilage grafts). Global follow-up after surgery for long-term aesthetic study was 8.5 years. Among the different autogenous that have been used in our series, the calvarial bone had the most interesting results in terms of resorption. In patients with important saddle nose deformity, we recommend calvarial bone as a material of choice for dorsonasal reconstruction. It provides excellent and natural long-term feel to the nasal complex.
