UNLABELLED Impact in vocal quality in partial myectomy and neurectomy endoscopic of thyroarytenoid muscle in patients with adductor spasmodic dysphonia the adductor spasmodic dysphonia is a severe vocal disorder characterized by muscle laryngeal spasms during speech, producing phonatory breaks, forced, strained and strangled voice. Its symptoms come from involuntary and intermittent contraction...

Although significant pressure gradients can be recorded across the left ventricular outflow tract in patients with hypertrophic cardiomyopathy, controversy exists regarding the presence or absence of true obstruction. Ten patients with hypertrophic cardiomyopathy were studied at the time of septal myectomy. A sterile continuous wave Doppler transducer was placed on the ascending aorta and direc...

BACKGROUND Internal anal sphincter hypertonicity with nonrelaxation can cause persistent constipation and obstructive symptoms in children after surgery for Hirschsprung's disease. Intractable symptoms traditionally have been treated with anal myectomy, which may be ineffective or complicated by long-term incontinence. The authors evaluated prospectively the use of intrasphincteric botulinum to...

OBJECTIVES Biventricular obstruction in hypertrophic cardiomyopathy (HCM) is uncommon, and some clinicians believe that, when symptoms are refractory to medical treatment, this severe form of HCM is best treated by transplantation. We describe our conventional surgical approach and outcomes to treat biventricular obstruction in HCM. METHODS From 1993 to 2013, we treated 11 symptomatic patient...

Background—The clinical efficacy of alcohol septal ablation for obstructive hypertrophic cardiomyopathy (HCM) has been demonstrated, but the long-term effects of the procedure remain uncertain. This study examined the survival of patients after septal ablation performed in a tertiary HCM referral center. Methods and Results—We examined 177 patients (mean age, 64 years; 68% women) who underwent ...

BACKGROUND There is controversy about preferred methods to relieve obstruction in hypertrophic cardiomyopathy patients still symptomatic after β-blockade or verapamil. METHODS AND RESULTS Of 737 patients prospectively registered at our institution, 299 (41%) required further therapy for obstruction for limiting symptoms, rest gradient 61 ± 45, provoked gradient 115 ± 49 mm Hg, and followed up...

OBJECTIVE To report the effect of weakening the superior rectus and inferior oblique (IO) muscles on ocular rotations. DESIGN Observational case series. We reviewed a 10-year period of medical records of consecutive patients who underwent bilateral 5- to 11-mm (mean, 8.0 mm; SD, 1.1 mm) superior rectus muscle recessions combined with an IO muscle recession, myectomy, or anterior transposition...

We sought to validate measurement of intraventricular pressure gradients (IVPG) and analyze their change in patients with hypertrophic obstructive cardiomyopathy (HOCM) after ethanol septal reduction (ESR). Quantitative analysis of color M-mode Doppler (CMM) images may be used to estimate diastolic IVPG noninvasively. Noninvasive IVPG measurement was validated in 10 patients undergoing surgical...

Because the left ventricular outflow tract is bounded anatomically by the ventricular septum and the anterior mitral leaflet, the dynamic obstruction of hypertrophic obstructive cardiomyopathy (HOCM) can be relieved by resecting either component. During recent years, most surgeons have practiced a traditional transaortic septal myectomy, as popularized by Morrow and associates (1,2). However, C...

PURPOSE To assess the incidence and investigate the functional impact of postoperative overcorrection following primary unilateral inferior oblique muscle recession and myectomy for inferior oblique overaction. METHODS A retrospective study of 79 consecutive patients undergoing inferior oblique myectomy (43) or recession (36) with a minimum 6 months of postoperative follow-up. All underwent o...
