Ocular manifestations after upper dorsal sympathectomy.

Fifty patients underwent ophthalmologic examination before and after bilateral upper dorsal sympathectomy performed for palmar hyperhidrosis. Postoperative examination was done during the first week, at 3 to 4 weeks and at 6 to 12 months after the operation. Immediately after surgery there were 18 patients with ptosis (6 severe) and 23 with miosis (12 severe). There were 19 patients with excessive lacrimation and some degree of congestion of conjunctival blood vessels was present in almost all patients. Uniocular decrease in tears was present in 2 patients. Most of these manifestations decreased with passage of time. At one year there remained only 3 patients with severe ptosis and 4 with severe miosis. The results suggest that the classical anatomic explanation of Horner's syndrome may require some modification.

Gustatory phenomena after upper dorsal sympathectomy.

In a series of 100 bilateral upper dorsal sympathectomies performed for palmar hyperhidrosis, gustatory sweating and other gustatory phenomena were reported by 68 of 93 patients (73%), followed up for an average of 1 1/2 years. These gustatory phenomena were quite different from physiologic gustatory sweating: a wide range of gustatory stimuli caused a variety of phenomena in varied locations. There was a negative correlation between the incidence of these phenomena and the occurrence of Horner's syndrome after sympathectomy. Analysis of our observations, and of clinical and experimental work of others, leads to the conclusion that gustatory phenomena after upper dorsal sympathectomy are the result of preganglionic sympathetic regeneration or collateral sprouting with aberrant synapses in the superior cervical ganglion.

Palmar hyperhidrosis and its surgical treatment: a report of 100 cases.

One hundred patients with primary palmar hyperhidrosis (HH) underwent bilateral upper dorsal sympathectomy (UDS) by the supraclavicular approach. Pre-operative epidemiological and clinical data are described. The immediate and late results, as well as the complications and side-effects are detailed. Follow-up was completed on 93 patients between four and 50 months after the operation (average 18 months). Of 93 patients, 91 had drying of the hands. In 58% some moisture returned to the hands but in no case did the hyperhidrotic state recur. Subjective patient evaluation was excellent or good in 83 patients (89%) and only one patient (a technical failure) was completely dissatisfied. Reasons for some degree of dissatisfaction with operation were mainly compensatory HH in non denervated areas, and Horner's syndrome. Compensatory HH usually decreased with passage of time and, permanent Horner's syndrome occurred in 8% of patients (4% of procedures). Technical failure can be avoided by use of frozen section examination intraoperatively. For severe cases of palmar HH that cause social, professional and emotional embarassment, bilateral simultaneous UDS by the supraclavicular approach is the procedure of choice: Morbidity is small, and almost all patients enjoy improved quality of life after the operation.

Pulmonary functional abnormalities after upper dorsal sympathectomy.

Pulmonary function tests were performed in a group of 15 patients before and 1 to 3 months after upper dorsal sympathectomy. Significant decreases in all compartments of lung volume and maximal expiratory flows were found. Serial studies in 3 patients showed improvement after 6 to 8 months.

Phantom sweating.

Phantom sweating is a sensation in which the patient feels that sweat is about to burst out of skin pores, but in which sweating never actually occurs. In a series of 100 patients undergoing bilateral upper dorsal sympathectomy for palmar hyperihidrosis, 82 patients were specifically questioned and 48 (59%) reported phantom sweating. Phantom sweating started soon after the operation, was triggered by the same stimuli that caused hyperhidrosis preoperatively, lasted for a few seconds, and tended to diminish with time. In an average follow-up of 18 months, the phenomenon disappeared in 11 patients (23%). Phantom sweating is probably a symptom of residual sympathetic activity.
