SNARE (soluble N-ethylmaleimide-sensitive factor
attachment protein receptor) protein complex is
cleaved to inhibit exocytosis of the neurotransmitters
such as acethylcholine (Goldsmith, Katz, and
Gilchrest, 2012) at the neuromuscular junction
(Shafik and El-Sibaik, 2000). The end result is a
chemodenervation of the cholinergic neurons, either
motor nerves or autonomic nerves, leading to
localized absence of muscle activity (Goldsmith,
Katz, and Gilchrest, 2012).
Botox produces its effect
by causing muscle paralysis, thus will inhibit
muscles spams in vaginimus. Improvement in
vaginismus is presumably due to paralysis of the
bulbospongiosus muscle. The latter appears to be
responsible for closure of the vaginal introitus on
trial of vaginal penetration. The other pelvic floor
muscles, levator ani and puborectalis muscles are
apparently not involved during vaginalpenetration as
the levator ani is inserted into the vaginal fornices
while the puborectalis is related to the lower part of
the vagina (Shafik and El-Sibaik, 2000).
Ghazizadeh and Nikzad reported the used of
Botox in the treatment of refractory vaginismus in
24 patients. In this study, Dysport (150 to 400 mIU)
was used. Twenty three patients were able to have
vaginal examinations 1 week after the procedure,
showing little or no vaginismus. One patient refused
vaginal examination and did not attempt coitus. Of
the 23 patients, 18 (78%) achieved satisfactory
intercourse, four (17%) had mild pain, and one was
unable to have intercourse because of her husband’s
impotence.
Botox procedure in this study consist of botox
injection in bulbospongiosus muscle, dilation with
the biggest dilator under anesthesia. The results were
100% patients have successful painfree penetration
without muscle spasm through self dilation using 4
inch silicone dilator at the same day of the
procedure, and 82,3% achieved sexual intercourse in
average of 4,5 weeks after the procedure.
Dilation, in the treatment of vaginismus is a
simple method buy may require long-term therapy
and fail in persistent cases (Shafik and El-Sibaik,
2000). Most women have tried dilation at home and
were either unsuccesful progressing to the larger
sized dilators or were too fearful to even begin
treatment (Pacik and Gelatta, 2017). Likewise,
behavioural therapy and psychotherapy, besides
being lengthy and expensive, may not succeed in
cureing the condition, especially in persistent and
severe degree of vaginismus. Meanwhile, botox
procedure is a simple, easy, rapid, and effective
treatment for vaginismus.
Side effects of botox including minor discomfort,
bruising (Goldsmith, Katz, and Gilchrest, 2012), dry
mouth, dysphagia, paresis extremities, or urine
incontinence (Shafik and El-Sibaik, 2000). Two
patients in this study report temporary mild urine
incontinence, this expected gone by the time botox
loses its effectiveness.
Botox is a safe drug when used according to the
manufacturer’s recommendations. During the past
20 years, Pacik has treated thousands of patients
using botos for dynamic facial wrinkles, excessive
sweating, migraine headhaches, and vaginismus,
with only rare minor untowards effects mostly the
result of migration of botox to nearby tissues.
Around 391 vaginismus patient were treated with
this botox procedure, there only few minor untoward
events such as temporary mild stress incontinence
(Pacik and Gelatta, 2017), same as this study. No
permanent sequele were noted.
Botox has a long duration of action up to 6
months,
loses its effectiveness within 4 to 6 months
(Goldsmith, Katz, and Gilchrest, 2012), but another
repeated botox procedure is usually not needed. At
this time period, patient has made the transition from
post-operative dilation to intercourse. In this study,
no patient was in need of re-procedure and there was
no reccurence during the follow-up period. Botox
procedure effected cure in all of the vaginismus
patients with no complications or recurrence.
5 CONCLUSIONS
Botox procedure appears to be safe and effective as
vaginismus treatment. This procedure has helped
many women to immediately start effective dilation
and also end their unconsummated marriage. It is
important for health care providers to know more
about vaginismus. Medical school, residency
program, and medical meetings are needed to spread
the knowledge about vaginismus and its treatment.
