[Uncommon tumors of the petrous bone. 4 cases (author's transl)].

Four cases of uncommon tumours of the petrous bone treated by surgery alone or combined with radiotherapy are reported. There was one case embryonic sarcoma in a 3-year-old female child and one case each of chondroid chordoma, isolated plasmocytoma and malignant fibroid chondrosarcoma or histiocytoma with giant cells. The signal symptoms (pseudo-petrositis, isolated paralysis of a vocal cord, sudden deafness) may be misleading. The most helpful diagnostic methods are frontal tomography and CT scanning.

[Esthesioneuroblastoma: general review about three new cases (author's transl)].

The authors report three new cases of olfactory esthesioneuromas. They emphasise, both the surgical and radiotherapeutic methods used, and staging according to Kadish. Very localized forms may be treated either by surgery or radiotherapy. Less localized forms require association of surgery and radiotherapy, with a craniofacial combined approach when extension goes beyong the lamina cribosa.

[Laryngotracheal stenosis treated by the Rethi operation : anatomical and functional (respiratory and vocal) results (author's transl].

On the basis of 25 cases of laryngotracheal stenosis of mescellaneous etiology, the authors report their experience of Rethi's operation carried out in 14 cases, 8 patients having received medical and instrumental treatment, 1 undergoing surgery for resection and anastomosis according to Pearson's technique and 3 receiving symptomatic treatment by tracheotomy because of inoperable stenosis. The frequency of postop-operative complications of Rethi's operation was analysed (essentially infectious, but also as a result of obstruction of the calibration prosthesis which represents a definite vial risk). Functional results were also assessed, being relatively satisfactory from a respiratory functional standpoint, but less good from a phonetic standpoint. The authors then define their present therapeutic attidude which leans, in the case of pure sub-glottal and sub-glotto-tracheal stenosis, towards a direct approach with resection anatomosis according to Pearson's technique rather than calibration procedures which remain the treatment ofa choice for glotto-sub-glottal stenosis.

[Facial nerve tumors: three cases (author's transl)].

The first one is a neurofibroma associated with a Charcot-Marie Tooth's disease involving all the tympanic segment of the facial nerve: extirpation and graft. Improvement of facial motricity to 42%. The second one is a small Schwannoma lateral to tympanic segment: extirpation without paralysis. The third is a large Schawannoma of the tympanic mastoïd segments involving the facial nerve to its division in the parotid gland, and with a limited extension in the cerebello-pontine angle. Extirpation and graft. Discussion and recent bibliography.

The place of cryosurgery in the treatment of subglottic angiomas of the infant.

The treatment of subglottic angiomas of the infant is not clear since radiotherapy was rejected. Tracheotomy is very often indicated. Spontaneous recovery of angioma may be hoped for, but it is slow. Cryotherapy with liquid nitrogen using a 2.5 mm cryoprobe has cured, in a few stages, 3 cases. It has to be employed carefully.

[The role of anastomosis resection in the treatment of stenosis of cervical trachea after resuscitation].

The authors describe a group of 9 resection anastomoses with end-to-end sutures of the cervical portion of the trachea after resuscitation. The operative results are analyzed first: in 8 cases the trachea recovered almost normal function in a very short time; one failure occurred : this was with a patient with considerable neuro-psychic sequelae following serious cranial traumatism. These results are then compared with 7 laryngo-tracheal plasties carried out according to the principles of Rethi's operation; it emerges from this study that circumferential resection followed by end-to-end anastomosis is still the ideal form of treatment for tracheal stenoses in view of the quality and consistency of the results. Operative technique is then described and, in giving their operative indication, the authors stress the need for medical and endoscopic treatment during the asphyxial crisis; this treatment is then suggested for removing the tube in open tracheal stenoses and in order to allow resection anastomosis with the trachea closed several weeks later.
