S. Caruso et al., Laryngeal cytological aspects in women with surgically induced menopause who were treated with transdermal estrogen replacement therapy, FERT STERIL, 74(6), 2000, pp. 1073-1079
Objective: To investigate the effects of estrogen replacement therapy (ERT)
on laryngeal cytology in postmenopausal women.
Design: Prospective open clinical trial.
Setting: Outpatient menopausal clinic in the Department of Gynecology, Univ
ersity of Catania, Catania, Italy.
Patient(s): Eighty-four healthy, surgically postmenopausal women, of whom 4
8 were treated with ERT and 36 were considered as a control group.
Intervention(s): Transdermal E-2 treatment by patches or gel, evaluation of
laryngeal cytology with cytobrush by indirect laryngoscopy, and questionna
ire for the voice history.
Main Outcome Measure(s): Changes in cytologic aspects of laryngeal cells wi
th respect to vaginal cytology by hematoxylin and eosin staining; subjectiv
e voice changes.
Result(s): Sixty-seven women completed the study. Ten women from the ERT gr
oup and five from the control group dropped out because of the invasive lar
yngoscope method; two subjects in the control group were excluded because o
f pathologies of the vocal cord. Hematoxylin and eosin staining confirmed s
imilar superficial-intermediate aspects of the cells between the laryngeal
and the vaginal smears in ERT-treated women. In the control group, both sme
ars showed aspects of atrophy-dystrophy. The ERT group had a subjectively b
etter quality of voice than the control group.
Conclusion(s): Our study confirms that the larynx is an estrogen target, as
are vaginal cells. ERT may provide prevention and treatment of dystrophic
pathologies of the vocal cords in postmenopausal women. (Fertil Steril(R) 2
