[Adult multilocular rhabdomyoma as etiology of a space-occupying lesion in the area of the neck].

Real rhabdomyomas belong to the rarest tumors in the human body. The origin of these benign neoplasms is in the cardiac or skeletal muscle, in the beginning, there are no significant symptoms and the tumor grows very slowly. Extracardiac rhabdomyomas seldom occur and are mostly located in the head and neck region. A multilocular occurrence represents a rarity. We describe a 77-year-old female patient with a multilocular adult rhabdomyoma in the parapharyngeal and paratracheal space. The tumor was accidentally found; the patient had not complained of any specific symptoms. After histological examination, complete resection was carried out. On discharge the patient showed no functional deficits. Long-term follow-up is necessary because local recurrences have been described.

[Sonographic imaging of upper eyelid tarsal radii when changing the direction of vision].

AIM: Aesthetic and reconstructive surgery of the upper eyelid attempts to restore aesthetic or functional deficits. Knowing of the anatomic relationships in these structures is very important. The aim of our study was to assess by ultrasound the upper eye lid tarsal curvature changes depending on movement of the bulbus. METHODS: In 50 people with healthy eyes we measured the diameter of the upper eyelid tarsal plate, the cornea, the bulbus and additionally the intraocular pressure. In measuring the upper eyelid tarsal plate we used transpalpebral ultrasound in a non contact mode with a 7.5 MHz linear array scanner, with the bulbus in median and in abduction position. RESULTS: In healthy eyes the diameter of the upper eye lid tarsal plate changes depend on movement of the bulbus. The mean diameter of the upper eye lid tarsal plate over the bulbus in medium position was 19.3 +/- 3.8 mm versus 30.1 +/- 6.3 mm in abduction position. This difference is statistically significant (p < 0.05). CONCLUSIONS: The results of the study indicate, that using ultrasound with a 7.5 MHz linear array scanner is appropriate for objective evaluation of relative changings of the upper eye lid tarsal plate diameter. The obtained data showed significant differences and must be taken into account when considering cosmetic and functional surgery of the upper eye lid, f. e. lidloading in facial palsy with gold or platinum implants.

[Lid retraction in endocrine orbitopathy. A new indication for "lid loading"].

Lid retraction in thyroid ophthalmopathy may lead to cosmetic and functional problems. Many surgical procedures are available to correct upper lid retraction. Only those procedures should be used that lead either to a limited lid lengthening or can be reversed in cases with complications. Upper lid gold weight implantation was first used to treat lagophthalmos in patients with facial palsy. Since 1995 only a few reports have appeared which discuss platinum as an implantation material. We report our experiences with a female patient who developed an upper lid retraction due to thyroid ophthalmopathy. Through implantation of a platinum weight which was adjusted exactly preoperatively, a symmetric palpebral fissure was achieved. Unilateral upper lid retraction with resultant eyelid asymmetry is a new indication for lid loading.

[Risks of upper eyelid gold implantation in peripheral facial paralysis].

Peripheral facial paresis is often accompanied by incomplete closure of the eyelids and may lead to varying degrees of keratopathy. Conservative therapeutic measures are often not sufficient. To achieve better lid closure tarsorraphy has been the primary method of treatment but has certain functional and cosmetic drawbacks for the patient. Alternatively gold weight implants have been used to close the upper lid by the force of gravity and if needed can be combined with further reconstructive facial surgery. From May 1994 to January 1997 29 patients with peripheral facial paralysis were treated with gold weight upper lid implants. Postoperative closure of the lids was sufficient in all cases, and there was a statistically significant decrease in lagophthalmos and improvement in keratopathy. Complications observed included ptosis (n = 5), cosmetically unacceptable bulging of the gold implant (n = 5), extrusion of the implant (n = 1) and the development of a low-grade corneal astigmatism (n = 7). In all cases of astigmatism correction was achieved by the fitting of cylinder glasses. In all, functional results achieved showed that the gold implant was superior to the cosmetically bothersome tarsorraphy.

[Corneal astigmatism as a special complication after lid-loading in patients with lagophthalmos].

UNLABELLED: Lid-loading with precious metals, described by Illig in 1958, has become increasingly important. because of its good functional and cosmetic results this method is superior to tarsorrhaphy. Furthermore, lid-loading can be combined with additional surgical techniques to achieve more dynamic lid-closure. In a prospective study we examined the results after lid-loading and discuss postoperative changes of the cornea. PATIENTS AND METHODS: Between May 1994 and June 1998, 36 patients with peripheral facial paresis and lagophthalmos were treated with a pretarsally fixed upper-lid implant. We used 99.99% gold for the implants with a weight of 1.5 g on average. RESULTS: In all cases we obtained sufficient postoperative lid closure which resulted in a statistically significant reduction in lagophthalmos and improved keratopathy. Postoperative complications were: pseudoptosis, remaining lagophthalmos, bulge, extrusion, migration and corneal astigmatism. Depending on the implant pressure, an astigmatism of 1-2 D developed in the vertical meridian. In all cases the initial visual acuity was reached by an ordination of cylindrical glasses. CONCLUSIONS: So far, corneal astigmatism as a complication after lid-loading has not received much attention in the literature. In our opinion, the development of astigmatism is caused by implants that are too heavy, an incorrect implant radius and individual cofactors (consistency of lid and cornea). There has been no need for an explantation in any case.
