Telescopic laryngoscopy.

Examination of the larynx is neglected as a regular part of the physical examination by many physicians, largely because of difficulties inherent in the angled-mirror technique of visualizing this area. Simple, relatively inexpensive right-angle telescopes especially designed for laryngoscopy are now available to facilitate this examination. In one study, abnormalities were found in 17 percent of consecutive asymptomatic patients receiving laryngoscopy. This procedure has an important role as a screening procedure and as a diagnostic aid in the workup of patients with laryngeal symptoms. The technique can be readily learned and used in everyday medical practice.

Endonasal findings using a fiberoptic telescope in postoperative cases of chronic sinusitis.

It is the purpose of this study to investigate the healing process in chronic sinusitis by means of a fiberoptic telescope. The patients were divided into 3 groups, in which various combinations of operative techniques were used. Group 1:53 patients with moderate chronic sinusitis. In this group endonasal ethmoidectomy and endonasal exposure of the sphenoidal sinus were performed. Group 2:73 patients with moderate or severe sinusitis. In this group a Caldwell-Luc operation was added to the operations which were used in group I. Group 3:8 patients, in which only endonasal ethmoidectomy was performed. In most cases, the maxillary sinus was cured, but in some of the cases the drainage opening was closed at an early stage. The epithelization of the ethmoidal sinus is mostly completed in about one month after the surgical operation. Adhesions between middle turbinate and lateral wall were seen regularly. Hypertrophic scars were observed in the posterior ethmoid, the ethmoidal roof and the lamina papyracea. We classified the healing process into 4 types. All postoperative infections were treated by antibiotics. Adhesions and scar tissue formations were treated endoscopically.

Telescopic extracranial approach to frontal mucoceles with intracranial extension.

Traditionally, frontal mucoceles were treated with open obliterative procedures such as collapse of the forehead soft tissues into the sinus or the more cosmetically appealing osteoplastic flap technique. When a frontal mucocele expands intracranially, these surgical procedures become difficult and with higher risk of cerebrospinal fluid leak and/or meningitis. In cases of a mucocele that extends both intracranially and anteriorly into the soft tissues, osteoplastic flap procedure may not be possible. We present our experience with telescopic intranasal surgery for the treatment of frontal mucocele with intracranial extension. The technique, which is based on intranasal marsupialization and stenting, was used in four patients with large mucoceles eroding into the cranium and the anterior soft tissues. The results were excellent and the patients are free of disease 1 to 4 1/2 years after surgery.

[Microbiological study via occluded telescopic catheter in patients under mechanical ventilation and suspected of pneumonia. Clinico-bacteriological follow up of the cases].

Pneumonias related to mechanical ventilation pose a serious diagnostic challenge and are responsible for elevated mortality. Conventional diagnostic methods are of little help. The introduction of invasive techniques such as bronchial catling via an occluded telescopic catheter (OTC) has proven to be an important advance in diagnosis and therapy. We have compared the bacteriological results obtained using OTC with those using conventional diagnostic methods such as tracheobronchial pumps (TBP) and hemocultures, and we have undertaken a bacteriological, clinical follow-up of the cases. Seventy-four patients under mechanical ventilation and suspected of pneumonia were under study. The study consisted to two consecutive phases of collecting bacteriological samples throughout the patient's evolution. A total of 121 fibrobronchoscopies were performed. The sensitivity obtained with OTC was 76%, and the specificity was 100%. The two techniques, OTC and TBP, coincided in 38% of the cases. According to the bacteriological results obtained with OTC, the antibiotic treatment was modified in 44.5% of the patients. The sensitivity of the OTC was significantly less in those patients were the last doses of antibiotic was administered within two hours of performing the procedure. The procedure of gathering secretions from the inferior respiratory tract with OTC possesses greater sensitivity and diagnostic specificity in patients with mechanical ventilation and pulmonary infiltrates and improves the diagnosis performed by other conventional and routine techniques such as TBA and hemocultures.

[Comparative study of protected alveolar lavage versus occluded telescopic catheter in patients with suspected pneumonia and under mechanic ventilation].

BACKGROUND: The pneumonias associated to mechanical ventilation present great difficulty in diagnosis and have a high mortality. The invasive diagnostic technique of choice in these patients is bronchial curettage by a double telescopic catheter with distal occlusion (OTC) based on its good sensitivity/specificity relation. Recently, the use of a variant of the classical bronchoalveolar lavage (BRL), bronchoalveolar lavage or protected alveolar lavage (PAL) has appeared in the diagnosis of conventional bacterial pneumonia. This new technique provides good specificity of OTC by its use with "protected" catheters and a high sensitivity due to exploration of a greater area of the lung. METHODS: Twenty patients receiving mechanical ventilation (MV) suspected of pneumonia in whom 21 fibrobronchoscopies (FB) were performed with OTC and PAL were studied with quantification of the cultures obtained being carried out. The OTC was performed according to the usual technique and PAL by the instillation of 40 ml of saline serum administered through a Combicath type catheter. RESULTS: OTC and PAL provided diagnostic results which coincided in 8 cases: the same germs were isolated at significant concentrations in six patients and in the two remaining cases direct immunofluorescence for Legionella was positive. PAL was diagnosed in 4 more cases with the diagnosis of viral inclusion bodies being possible in one upon cytologic examination. The count of cells with intracellular bacteria (ICB) was greater than 7% and was always related with positivity in the PAL. CONCLUSIONS: A greater sensitivity was observed with the protected alveolar lavage technique. Moreover, this technique makes virologic investigation and the counting of cells with intracellular bacteria, which may be a marker of rapid diagnosis of bacterial pneumonia, possible.

The DIA anatomic abutment system and telescopic prostheses: a clinical report.

Implant-supported prostheses may benefit from the versatility of design and favorable appearance offered by telescopic restorations. This project investigated the effectiveness of 208 abutments designed and produced by Dental Imaging Associates and the 73 prostheses supported by them over a 2-year period. No complications were found in the single-tooth group, although the sample was small (n = 7). Only 8.17% of the 208 abutment screws became loose during the initial postloading period. Once retightened, 2.4% of the total loosened for the second time. Higher screw-loosening rates were found in maxillary restorations, while the inclusion of a distal cantilevered pontic produced a significant increase in maintenance requirements.

Use of inverted telescopic corrections incorporating soft contact lenses in the (partial) correction of aniseikonia in cases of unilateral aphakia.

Soft contact lenses have been successfully adapted to inverted telescope units used to restore effective binocularity to selected unilateral aphakic patients. Techniques for adapting such units to the patient have been outlined and results have been reviewed. Differences between hard and soft contact lens techniques have been contrasted. The practitioner is encouraged to utilize these methods when binocularity would be a clear advantage to the patient with unilateral aphakia. The author hopes to adapt these techniques to the treatment of infants and young children in the future.

Telescopic prostheses for implants.

This retrospective study investigated the outcome of 73 telescopic implant-supported fixed prostheses. Fifty-four prostheses were entirely cement-retained, and 19 incorporated a screw-clamping unit. The rate of complications was low and in most cases minor in nature. Cement-retained prostheses involving a distal cantilevered extension required the greatest postoperative maintenance. Despite the small number of combined screw- and cement-retained prostheses, the lack of complications and ease of retrievability make this approach worthy of further study.

Radiographic/surgical template incorporating metal telescopic tubes for accurate implant placement.

The dental literature is replete with information on various implant surgical template designs and imaging techniques for presurgical assessment of dental implant sites. Seldom are these two aspects combined in a practical and effective manner to fabricate a guide for precise implant placement. Unless detailed, three-dimensional images of the underlying bone are obtained, the use of a template is ineffective. This article describes a radiographic/surgical template that utilizes a series of telescoping metal tubes as radiographic markers and as implant drill guides.
