ABSTRACT
Frontobasal injuries and some other diseases of frontal sinuses sometimes require radical surgery with the obliteration of the sinus. A cosmetic correction of the forehead and supraorbital arches has to be performed after such a procedure. Nowadays, there is a wide choice of alloplastic materials on the market. We tried polymethyl methacrylate implants in correction of the exterior appearance of the forehead and supraorbital arches and followed the behaviour of the implants up to 25 years after surgery. The result was 18 (94.7%) successful implantations and one failure (5.3%) with a mild sagging of the borders of the implant. Polymethyl-methacrylate proved pliable for work and modelling, not invasive for the organism and stable. In conclusion, the cure of some frontobasal injuries and diseases with the first surgical step followed by cosmetic correction of the forehead and supraorbital arches (2nd surgical step) using this alloplastic material provides a safe, durable and aesthetically satisfactory solution for the patient.

The subject of this study is the electromyographic investigation of the velopharyngeal sphincter structures. Seventy-five patients underwent examination, both patients with symptoms of velopharyngeal insufficiency and patients who were thought to have latent pathological sphincter changes based on local findings. A control group of 10 healthy examinees was also investigated. On the basis of electromyographic findings we divided patients into 2 groups: 57 patients without neuromuscular disorders and 18 patients with neuromuscular disorders of the velopharyngeal sphincter. Twelve patients from the latter group had acute, and 6 had chronic lesions of the velopharyngeal sphincter. Particular cases of illness within these 2 groups were investigated further. This study shows the usefulness of electromyography for diagnosing the exact causes of velopharyngeal insufficiency and for choosing the best approach to treatment.

It is well known that secondary or revised rhinoplasty is big problem in plastic surgery. During the five year period (1987-1991) 273 rhinoplastic surgeries were done at the ORL-clinic in Rijeka, out of which 42 have been submitted to revision (15.2%). We divided the postsurgical deformations, according to the anatomical criterion, into 3 groups; the upper, the lower and the middle part of the nose. The most frequent deformations of the lower, middle and upper third of the nose are acute septolabial angle, i.e. a dependent tip (19%), pollybeak (33%) and excessive dorsal removal (21%), respectively. The cases have been systematically studied out.
