Subglottic haemangioma in the infant: contribution by CO2 laser.

The availability of the low intensity CO2 laser beam, and the possibility of defocalization that is associated with control of subglottic high frequency jet ventilation, requires a more interventionist attitude regarding dyspnoea caused by a subglottic haemangioma in the infant. It is indeed possible reliably to reduce the size of the subglottic haemangioma, and thus to avoid a lengthy period of intensive care, as well as the problems of prolonged intubation or tracheostomy for drainage, while also avoiding long term steroid therapy. This approach in no way affects the spontaneous evolution of subglottic haemangioma in the infant; there is a tendency for the haemangioma to regress after the age of one year.

Initial long-term results of collagen injection for vocal and laryngeal rehabilitation.

The records of 14 patients who have benefited from intralaryngeal injections of ZCI collagen for at least 3-4 years were reviewed. All patients still living were evaluated. Qualitative phonatory measurements included laryngostroboscopy and frequency voice analysis, while quantitative studies included maximum phonation times and phonatory quotients.

[CO2 laser treatment of the glottic sulcus and of epidermoid cyst. Technic and results].

The CO2-lasers of the new generation are equipped with milliwatts, super-pulse, small spot size (700 U or less). These technical improvements safe permit in resection of vocal fold benign lesions like polyps, nodules, or even sulcus glottidis. Our resection technique for sulcus glottidis and epidermoïd cysts is presented in 18 cases.

A clinical correlation between hypozincemia and tinnitus.

We examined a group of 115 patients suffering from tinnitus and have attempted to find a statistically significant correlation between the tinnitus experienced and low blood zinc levels (hypozincemia). No particular correlation could be made between the nature of the tinnitus experienced and hypozincemia except for the continuation of head noises, these being more frequently associated with hypozincemia when they are intermittent. Two hypotheses of pathogenesis are proposed to explain this phenomenon and are based on the importance of zinc to the syntheses of enzymes and proteins.

[The zinc sulfate overload test in patients suffering from tinnitus associated with low serum zinc. Preliminary report].

This work studies the efficiency of the zinc overloading in the treatment of patients suffering from tinnitus with hypozincemia. The authors have positive results about 52% of cases: in 15% there was a good amelioration and in 37% there was a little but significant amelioration of their symptoms. The authors have also found on that this type treatment with zinc of overloading is more efficient in males than in females.
