Abstract Objectives This paper describes a simple method of securing tissue coverage of the great vessels at the initial surgery by rotating the divided sternal heads of the sternocleidomastoid muscle, a routine step during laryngectomy, and approximating them to the prevertebral fascia. The paper presents an illustrated case example where this technique in a salvage laryngectomy repair resulted in a protected vascular axis following a salivary leak. Results Since utilising this technique, there has been a marked reduction in the requirement of subsequent flap procedures to protect vessels, and no episodes of threatened or actual carotid blowout.

The Eagle's syndrome is a disease is caused by irritation of the nervous, vascular and muscular structures the surround the subcutaneous process of the temporal bone. A syndrome manifested by chronic pain at the deep part of the lateral region of the face, which irradiates in to the root of the tongue, pharynx and ear, dysphagia, symptoms of disorders of the circulation of the brain. Symptoms of Eagle’s syndrome are founding various otolaryngological, dental, neurological diseases. Aim: due to the lack of information on the development and course of the stylohyoid syndrome, conservative treatment and the complexity of diagnosis, the anatomical features of the hypertrophied styloid process, their length and angles of deviation and the need for local impact on the process, the stylohyoid ligament and the neurovascular bundle, to varying degrees presenting to the styloid process, it becomes necessary to develop the most effective and simple method for diagnosis a hypertrophied styloid process and to optimize the need for CT examination with contrasting of the great vessels of the neck and performing functional tests. Materials and methods: Over the past 9 years, we examined and treated 184 patients. The appeals were random, with no specific focus. Of these, there were 133 women (72.3%), men – 51 (27.7%); age – from 25 to 70 years old: 25-30 years old – 15 people (8.1%), 30-45 years old – 116 (63%), 45-60 years old – 38 (20.6%), 60-70 years old – 15 (8.1%); the duration of the disease is from 1 to 10-15 years. Our work was aimed at improving and simplifying the diagnosis of the hypertrophied styloid process during the initial treatment of the patient in an outpatient and polyclinic conditions using functional tests, determining the need to refer patients to CT examination to visualize the relationship of the elongated styloid process with the main vessels of the neck, the possibility of pressure of the append age on the vessels and nerves of the neck, both at rest and in the movement of the head and neck, the development of impaired blood circulation in the brain due to impaired blood flow through the arteries and impaired out flow through the veins, and the development of corresponding symptoms in addition to those described in the literature. Due to the difficulty of diagnosing hypertrophy of the styloid process of the temporal bone in an outpatient and polyclinic conditions and the lack of awareness of practical otolaryngologists about this problem, we proposed a scheme for examining patients with suspicion of this problem.

Aposteriori deblurring of high resolution electron micrographs of weak phase objects can be performed by holographic filters [1,2] which are arranged in the Fourier domain of a light-optical reconstruction set-up. According to the diffraction efficiency and the lateral position of the grating structure, the filters permit adjustment of the amplitudes and phases of the spatial frequencies in the image which is obtained in the first diffraction order.In the case of bright field imaging with axial illumination, the Contrast Transfer Functions (CTF) are oscillating, but real. For different imageforming conditions and several signal-to-noise ratios an extensive set of Wiener-filters should be available. A simple method of producing such filters by only photographic and mechanical means will be described here.A transparent master grating with 6.25 lines/mm and 160 mm diameter was produced by a high precision computer plotter. It is photographed through a rotating mask, plotted by a standard plotter.

In situ preparation of cell cultures for ultrastructural investigations is a convenient method by which fixation, dehydration and embedment are carried out in the culture petri dish. The in situ method offers the advantage of preserving the native orientation of cell-cell interactions, junctional regions and overlapping configurations. In order to section after embedment, the petri dish is usually separated from the polymerized resin by either differential cryo-contraction or solvation in organic fluids. The remaining resin block must be re-embedded before sectioning. Although removal of the petri dish may not disrupt the native cellular geometry, it does sacrifice what is now recognized as an important characteristic of cell growth: cell-substratum molecular interactions. To preserve the topographic cell-substratum relationship, we developed a simple method of tapered rotary beveling to reduce the petri dish thickness to a dimension suitable for direct thin sectioning.
