Premetamorphic Rana pipiens tadpoles at Stages V to VIII on a 12L/12D cycle with photoperiod from 0800 to 2000 hr were treated with 30 micrograms/liter thyroxine (T4) by immersion for various daily 8-hr spans, or by daily intraperitoneal injection at different times with 0.1 to 10 micrograms T4 or 10 micrograms prolactin (PRL), in order to see if the rate(More)
Pectoralis major musculocutaneous flaps were used for reconstruction after transmaxillary buccopharyngectomy to treat 22 patients with large oropharyngeal tumors. Short and medium term results are discussed. Large excisions such as these raise many functional problems, even though the use of a musculocutaneous flap for reconstruction is a valid procedure(More)
Attitudes adopted when confronted with a solid cold thyroid nodule are analyzed in the light of recent developments in paraclinical data represented essentially by results of immunological, ultrasound and fine needle cytopuncture examinations. The use of these new surveillance technics frequently allows surgery to be deferred, while if on the contrary(More)
Results of radiologic, radiotomographic and CT scan imaging of patients with major aplasias of ear are presented. In the absence of an indication for functional surgery these explorations allow evaluation of the risk of an epithelial inclusion within an undetected anlage of external auditory canal. When functional surgery is indicated results of these(More)
Results of 219 ossiculoplasties performed during closed technic tympanoplasties over a 7-year period are reviewed. Ossiculoplasty involved the implantation of ossiculo-tympanic plate homografts, ossicular auto- or homo-grafts or Klein type prostheses. Results are analyzed as a function of disease causing the ossicular lysis, types of mounting and number of(More)
A retrospective study of 106 retraction pockets has been achieved: Part of them was treated with ventilation tubes (23 cases) and an other part was treated by tympanoplasty (83 cases). Our purpose was to verify if our indications were wright. We concluded that it is correct to operate the fixed retraction pockets and it is not dangerous. Concerned the(More)
Long-term anatomic results of 170 tympanic homografts performed in the Necker-Enfants-Malades hospital, France between 1977 and 1983 showed high frequency of complications: early perforation (17.7%); late perforation (14%); myringitis (8.5%); recurrence of retraction (7.31%); lateralization (9.4%). These complications are of much higher frequency than after(More)
