Does reduction mammaplasty improve lung function test in women with macromastia? Results of a randomized controlled trial.

BACKGROUND: To determine the effects of reduction mammaplasty on lung function in women with mammary hypertrophy (macromastia), a prospective, randomized, controlled trial was conducted at the Academic Surgery and Plastic Surgery Units, Castle Hill Hospital, Cottingham, United Kingdom. METHODS: Seventy-three women who were referred for consideration of bilateral breast reduction surgery were randomized into either an early intervention group (surgery within 6 weeks) or a control group (surgery 6 months after recruitment). Each group had two sets of lung function tests: the intervention group had one before and one 3 months after surgery and the control arm had one test initially and a second test 4 months after randomization and before surgery. The main outcome measure was the lung function test. RESULTS: Sixty-five patients completed the study. The mean age was 39 years (SD, 12 years); both groups were equally matched for age, smoking status, social class, and educational status. By independent t test, there was no significant difference in lung function in the two groups. Subgroup analysis of the intervention group demonstrated a positive correlation between specimen weight and forced expiratory volume/vital capacity, forced expiratory volume/forced vital capacity, peak expiratory flow rate, and forced vital capacity. A paired sample t test revealed a significant improvement in the percentage of forced vital capacity performed/forced vital capacity predicted. CONCLUSION: The improvement in pulmonary function following reduction mammaplasty correlates with specimen weight resected.

Effects of reduction mammoplasty on upper-limb nerve conduction across the thoracic outlet in women with macromastia: a prospective randomized study.

UNLABELLED: Macromastia is a common problem. The physical complaints include upper body pain and aches. There have been anecdotal reports of neurologic deficits in the nerves emanating from the lower trunk of the brachial plexus. This is thought to be due to pressure on the lower trunk from both the first rib and tilting forward of the coracoid process. Other anecdotal reports have centered on the correction of neuropraxia of the ulnar nerve following bilateral breast reduction (BBR). We investigate the effect of BBR on the electrophysiological function of the nerve supply to the upper limbs in women with macromastia. METHODOLOGY: Consecutive patients undergoing BBR were randomized into 2 groups, depending on time of surgery. None had any prior neurologic disorder. Each patient had a comprehensive neurologic assessment and 2 electrodiagnostic neurophysiologic tests. Group 1 had 2 tests, one before surgery and a second 3 months postsurgery, while Group 2 had 2 sets of tests, one initially and a second test 4 months later (control). The outcome measures include somatosensory evoked potential (SSEP) (median and ulnar), F-wave median and ulnar latencies. The F waves measure the integrity of neural conduction time from the anterior horn cells to the hypothenar and thenar muscles reflecting lower trunk function. The SSEP of the median nerve measure the integrity of the nerve fibers traversing the upper trunk of the brachial plexus and the ulnar nerve SSEP that of the lower trunk. There was no statistical difference in the conduction times. BBR does not have any effect on the upper limb nerve conduction times.

Ultrasound guided minimally invasive breast surgery (UMIBS): a superior technique for gynecomastia.

The last 30 years has seen a shift in surgical treatment of breast diseases to less invasive, more conservative treatment options. The mammotome equipment was originally introduced as a diagnostic tool, but advances in technology have extended its role to therapeutic procedures. The mammotome device (8-gauge) is inserted through a cosmetically placed 4-mm scar and breast tissue is resected sequentially using a suction facility without the need to remove the biopsy device. This is done under ultrasound guidance. Operative morbidity and postoperative score for cosmesis and patient satisfaction were recorded prospectively. Patients were reviewed in the clinic after 6 to 8 weeks. Five patients (4 unilateral, 1 bilateral) with idiopathic gynecomastia were treated. Mean age was 41.8 years (range, 16-88 years) with a median procedural time of 32 minutes. No postoperative morbidity was noted and mean cosmetic score was 9/10. The mammotome is an emerging minimal invasive tool that is safe and ensures excellent cosmesis and very high patient satisfaction rates.
