Clinical assessment of a new computerised objective method of measuring facial palsy.

OBJECTIVE: To compare the results using a new computerised objective method of assessing the degree of facial palsy with the results obtained using traditional clinical methods. DESIGN: Prospective computerised pixel change analysis and clinical evaluation of videos. SETTING: Tertiary referral centre. PARTICIPANTS: Subjects with varying degrees of unilateral facial palsy. METHODS: Comparison of the results obtained from an objective computerised method, the Glasgow Facial Palsy Scale, with the standard subjective clinical methods of the House-Brackmann Scale, Yanagihara, Sunnybrook Grading Scales and the objective clinical Stennert-Limberg-Frentrup Scale. RESULTS: Statistical analysis of the results from the objective computerised system indicated that there is an averagely strong correlation with the results from the House-Brackmann (Spearman's coefficient of 0.64), Sunnybrook (Pearson coefficient of 0.7) and Stennert-Limberg-Frentrup Scale (Pearson coefficient of 0.65), and it therefore has the ability to produce consistent results that agree with traditional clinical methods. It has a strong correlation with the Yanagihara Grading Scale (Pearson coefficient of 0.72) indicating that it may also have the ability to detect and record variations in the different regions of the face. CONCLUSION: This new computerised objective method of assessing the degree of facial palsy shows promise as a standardised objective method of assessing the degree of facial palsy.

Early experience on a modern, thin cochlear implant family. A retrospective, international multicenter study.

RATIONALE: Cochlear implantation is the most effective method of rehabilitation for patients with severe to profound sensorineural hearing loss. Binaural hearing forms the basis of the development of hearing-associated cortical networks in infants and toddlers, but simultaneous bilateral implantation is often postponed due to the demands of classical surgical methods, which are associated with large incisions and a deep bony well. OBJECTIVE: The authors report on the use of a modern, thin implant type and the possibilities it provided to simplify the surgical technique. METHODS AND RESULTS: Recent models of the Cochlear™ Nucleus® implant family were studied in an international retrospective multi-center study: 6 otolaryngologists in 5 centers shared their experiences on 73 consecutively implanted, thin implants. The surgical incision could be made shorter than before and only shallow bony wells or none at all were created in 4 out of 5 centers. No complications occurred. DISCUSSION: This study underlines that implants with thin electronics capsules enable a simplified, fast and safe implantation procedure that allows simultaneous bilateral cochlear implantation.

A retrospective comparison between non-conveyed and conveyed patients in ambulance care.

BACKGROUND: Not all patients where an ambulance is dispatched are conveyed to an emergency department. Although non-conveyance is a substantial part of ambulance care, there is limited insight in the non-conveyance patient population. Therefore, the study aim was to compare demographics, initial on-scene reasons for care, and vital signs between conveyed and non-conveyed patients attended by an ambulance. METHODS: A retrospective study of ambulance runs from 2 EMS regions in the Netherlands in 2016 was performed. For each ambulance run demographics (age, gender and geographical location), initial reasons for care categorised into the ICD-10 classification system, and vital functions or observational scales (according to the national ambulance care protocol) were collected and analyzed. RESULTS: 54.797 ambulance runs met the inclusion criteria, of which 14.383/54.797 (26.2%) resulted in non-conveyance. There was no significant difference in gender, but the non-conveyance group was significantly younger (48.5 (±26.4) years) compared to the conveyance group (60.7 (±22.2) years) (p = .000). The most common initial reasons for care for the conveyance group could be classified into chapter-9 diseases of the circulatory system, chapter-19 injury, poisoning and certain other consequences of external causes, and chapter-10 diseases of the respiratory system. The most common reasons for care in the non-conveyance group could be classified into the chapter-9 diseases of the circulatory system, chapter-19 injury, poisoning and certain other consequences of external causes, and -chapter-5 mental, behavioral and neurodevelopmental disorders. The total percentage abnormal vital functions/observation scales between the conveyance (69.5%) and non-conveyance group (58.6%) was significantly different (p = .000). 15 out of 17 vital functions/observation scales are significantly different between the conveyance and non-conveyance group. CONCLUSIONS: This study shows that non-conveyed patients are younger, are more likely to be in (highly) rural areas, and more often have initial reasons for care related to mental, behavioral and neurodevelopmental disorders (ICD-10 chapter 5). Although abnormal vital functions/observation scale were more prevalent in the conveyance group, 58.6% of the non-conveyed patients had at least one abnormal vital function/observation scale.

Airway complication after thyroid surgery: minimally invasive management of bilateral recurrent nerve injury.

OBJECTIVES: After bilateral vocal cord paralysis, the consequent paramedian position usually necessitates tracheostomy for at least 6 months, when the paralysis is potentially reversible. In the present study a reversible endoscopic vocal cord laterofixation procedure was used instead of tracheotomy. STUDY DESIGN: Prospective study of 15 consecutive patients aged 33 to 73 years who suffered bilateral recurrent laryngeal nerve paralysis after thyroid surgery. METHODS: The operation was performed endoscopically with a special endo-extralaryngeal needle carrier instrument. Two ends of a monofilament nonresorbable thread were passed above and under the posterior third of the vocal cord and knotted on the prelaryngeal muscles, permitting the creation of an abducted vocal cord position. If movement of one or both vocal cords recovered, the suture was removed. Regular spirometric measurements and radiological aspiration tests were conducted on the patients. RESULTS: During the follow-up period of 3 to 40 months, airway stability was demonstrated in all but one patient. After the repeated lateralization procedure, this patient's breathing improved. Partial or complete vocal cord recovery was observed in eight patients. In six patients further voice improvement was achieved when the threads were removed after vocal cord medialization or recovery. Mild postoperative aspirations ceased in the first postoperative days. CONCLUSIONS: This management approach offers an alternative to tracheostomy in the early period of paralysis, avoids terminal loss of voice quality, and provides a "one-stage" solution for permanent bilateral recurrent nerve injuries.

Minimally invasive surgery for posterior glottic stenosis.

Posterior glottic stenosis most commonly results from prolonged endotracheal intubation. The tube causes decubitus and perichondritis with a consequent scar tissue formation in the posterior commissure that often limits the abduction of the vocal cords. Many different surgical methods are known for the treatment, but in most cases temporary tracheostomy is required. We recommend a minimally invasive method to avoid tracheostomy, which is a very inconvenient state for the patient. The scar of the posterior commissure is excised endoscopically with the CO2 laser, and a modification of the endoextralaryngeal vocal cord laterofixation described by Lichtenberger is used to lateralize 1 or both vocal cords until the posterior commissure is completely reepithelialized. In this article we report on the first 5 cases. All patients had satisfactory airways immediately after the laterofixation procedure, which proved to be stable later on as well. In the cases of moderate stenosis, further scarring was prevented, and after the healing of the mucosa in the posterior glottic area, the laterofixation sutures were removed. The vocal cord mobility was recovered in the cases in which the cricoarytenoid joint was not fixed. In 1 case of severe stenosis (bilateral cricoarytenoid joint fixation), the procedure yielded only partial improvement.

Leiomyosarcoma of the larynx. Review of the literature and report of two cases.

Leiomyosarcoma of the larynx is an extremely rare malignancy. Until now, only 35 cases have been reported, and only 19 were reported in English. We present 2 new cases observed in the last 3 years at our department. Correct histologic diagnosis can only be made on immunohistochemical and electron microscopic grounds. A 65-year-old man previously treated for a premalignant vocal cord lesion and a 31-year-old woman who previously underwent operation on a benign vocal cord lesion are presented. Only surgical treatment (total laryngectomy and endolaryngeal laser resection) was performed. Thirty-six and 22 months after the initial surgical intervention, both patients are alive and well, with no evidence of local recurrence or distant metastasis.

Clinical and experimental studies on the incorporation of materials applied as covering for the labyrinth window.

From among the materials used for covering the labyrinth window, of the foreign materials gelfoam proved ideal from clinical and experimental points of view, while of the materials of interstitial origin, fascia, perichondrium, and periosteum seem to be suitable for covering the labyrinth window, resp. for transplantations in the tympanic cavity.

Cochlear implantation of a Hungarian deaf and blind patient with discharging ears suffering from Behçet's disease.

A case is reported in which a Nucleus 22 channel intracochlear device was implanted a deaf/blind Hungarian adult with discharging ears suffering from Behçet's disease. Preconditioning surgery was employed three months prior to the implantation procedure to ensure a sterile, dry protected environment for the electrodes. One month after implantation, the patient exhibited excellent auditory discrimination capability at the time of the first switch on. We suggest that some deaf/blind individuals may serve as very good candidates for intracochlear implantation.

Cochlear implantation in a patient with grand mal epilepsy.

A case is reported in which a Nucleus 22 channel intracochlear implant was used to treat a deaf Hungarian woman (aged 37 years) with a 34-year history of grand mal (GM) epilepsy maintained on carbamazepine-diazepam combination therapy who had not benefited from conventional hearing aids. Pre-operative electrical stimulation of the acoustic nerve, however, exhibited a good nerve function with no evidence of abnormal waveforms in the electroencephalogram (EEG). Successful intracochlear insertion of the 22 electrode resulted in a 40 dB hearing improvement at frequencies 250-2000 Hz in the implanted ear with no signs of pathologic wave activity at either the previously recognized epileptic focus (fronto-precentral region) or indeed, in other regions of the brain at use of the implant. We conclude that intracochlear implantation per se is not a hazardous intervention in patients with fronto-precentral epileptic foci.

Surgical treatment of Bell's palsy.

In 17 patients with Bell's palsy not treated or not responding to conservative therapy, vertical and horizontal decompressions were performed between days 7 and 10, relying primarily on the findings of neuromyography. Four patients (23.5%) recovered fully. Further 35 patients were operated after the regeneration period for absence of reinnervation signs between the 3rd to 6th months. An unusually marked and rapid improvement was noted in a 20-year-old female patient. In a 49-year-old male patient a neurinoma was found on the tympanal section of the facial nerve. Residual symptoms were significantly milder after early and late decompressions compared to spontaneous recovery of paralysis associated with total degeneration. There was no difference between the two operated groups.

Pharyngeal localizations of branchial cysts.

Two cases with unusual pharyngeal localizations of branchial cysts medial to the great neck vessels and pharyngeal constrictor muscle are presented. The authors reviewed the theories of origin of the branchial cysts and the surgical treatment options. In their first case the transoral approach was chosen. Because of previous unsuccessful attempts at surgical treatment, the pharyngeal cyst was extremely adherent to adjacent tissue with much scar tissue, and it was very difficult to remove. As a result of this disappointing operation, an external neck exploration was indicated in the second patient. Histological examinations confirmed that the excised cysts were branchial in both cases.

Vocal cord laterofixation as early treatment for acute bilateral abductor paralysis after thyroid surgery.

Bilateral vocal cord palsy due to a lesion of the recurrent laryngeal nerves is a serious complication of thyroid operations, with the airway obstruction usually necessitating tracheostomy. In the cases presented, a stable airway was ensured with endolaryngeal cord laterofixation instead of tracheostomy. The operation was performed with the endo-extralaryngeal needle carrier instrument devised by Lichtenberger. During the operation, only minor surgical trauma occurred in the larynx. The fixing thread was then removed following recovery of contralateral vocal cord function, resulting in an improvement in the voice. Four patients are described who suffered bilateral recurrent laryngeal nerve palsy after thyroid gland operations. During the follow-up period of 3-12 months, airway stability was demonstrated by regular spirometric measurements. The simple method recommended spares patients the possible complications of tracheostomy.

Laser lingual tonsillotomy.

The classic surgical procedures for treatment of complaints caused by hyperplasia and chronic inflammation of the lingual tonsil are difficult, and may involve serious complications. Eleven patients with hyperplasia of the lingual tonsil were treated with a Tungsram TLS 61 CO2 laser coupled to an operating microscope. The average duration of hospitalization was 3-4 days. The advantages of the use of a CO2 laser are haemostasis, sealing of the nerve endings, decrease of postoperative pain, and no postoperative oedema, which is important because of the closeness of the larynx. There were no serious complications either during surgery or in the postoperative period, and the complaints of all 11 patients were eliminated or reduced.

Reconstruction of spinal accessory nerve after radical neck dissection.

Resection of the spinal accessory nerve in cases of radical neck dissection often causes considerable damage to the function of the shoulder girdle; it leads to limitation of the motion of the upper limb and pain in the shoulder girdle. It seems a sensible compromise to reconstruct the spinal accessory nerve in one-stage operation with radical neck dissection, which can often prevent extensive atrophy of the trapezius muscle, with a resultant improvement in the chance of successful rehabilitation. The technique of the operation is described: after completion of radical neck dissection, in one-stage operation an autogenous nerve transplant from the n. auricularis magnus is sewn onto the central and peripheral stumps of the spinal accessory nerve, which are protected by a "vein-muff" and the fascia of the muscle. After such spinal accessory nerve reconstruction, subjective complaints and objective symptoms were much milder in 6 patients than in the control group, which consisted of 10 patients who underwent a similar operation but without spinal accessory nerve reconstruction.

Combined use of endoscopic CO2 laser excision of a marginal laryngeal tumor, radical neck dissection, and perioperative laterofixation of the opposite vocal cord.

We report the use of endoscopic laser excision of a marginal laryngeal tumor, radical neck dissection, and laterofixation of a paralyzed vocal cord in a 66-year-old man who had an early-stage right supraglottic endolaryngeal tumor and ipsilateral neck metastasis. He had a left vocal cord paralysis after a left pneumonectomy that was performed 5 years previously. The primary laryngeal tumor was excised by endoscopic CO2 laser resection, and a simultaneous radical neck dissection was carried out. Postoperatively, severe inspiratory dyspnea developed because of the surgical intervention on the right side causing moderate laryngeal edema and limited movement of the right vocal cord in addition to the paralyzed left side. An endolaryngeal laterofixation of the paralyzed left vocal cord was performed to provide the patient with an adequate airway instead of tracheostomy. This patient had a 2 years' follow-up without recurrence of tumor. In the meantime movement of the right vocal cord has returned, so that the patient's voice was socially acceptable and he has a functioning larynx.

The prognostic value of facial nerve conduction velocity in patients with Bell's palsy.

The facial nerve conduction velocity was measured in 30 healthy subjects (60 sides) and in 51 patients with a unilateral Bell's palsy. The normal value was 47.8 +/- 5.1 m/s. Incomplete recovery was common in Bell's palsy when the velocity was below 30 m/s. Mild synkinesis was observed in only one patient when the nerve conduction velocity was above 30 m/s. When the degree of degeneration revealed by electroneuroneography did not exceed 60%, the conduction velocity was in the normal range. For degrees of degeneration in excess of this, the conduction velocity decreased in parallel with the increase in the degree of degeneration.

Peroral endoscopic removal of a regurgitated giant polisegmented fibrovascular polyp of the esophagus.

BACKGROUND: Giant fibrovascular polyps (FVP) are relatively rare benign neoplasm of the upper esophagus and hypopharynx. Without previous history, their diagnosis might be difficult as the endoscopic findings are sometimes misinterpretedMaterials and methods: The present report describes a case, in which the patient regurgitated his giant polypoid mass into his mouth and captured it between his teeth and buccal surface until the emergency endoscopic removalResults: After one-year of follow-up, the patient is going well, without recurrence of his polypConclusion: Although the adequate therapy for these lesions is mainly the open surgical resection, most often via cervical esophagotomy, in our case the polyp was removed successfully by peroral endoscopic operation.

Neuromyography in the diagnostics of Bell's palsy.

After summing up the principles and technique of neuromyography, the authors illustrate their clinical application with several cases from their practice. The method is suited for monitoring the degeneration processes in Bell's palsy or other acute peripheral facial nerve pareses. The measurements permit estimating the duration of recovery and the probability of residual signs. The method helps the indication and timing of decompression surgery. In spite of certain difficulties involved in the procedure, its introduction into the diagnostics of facial nerve diseases is recommended.

Treatment of travellers' diarrhoea with fleroxacin: a case study.

A double-blind, randomized, placebo-controlled trial was conducted to evaluate the efficacy and safety of fleroxacin for one or two days as treatment for patients with travellers' diarrhoea. A total of 195 patients who were suffering with acute diarrhoea of less than six days' duration were enrolled. One hundred and fifty-one patients, of whom 49 received placebo, 54 received fleroxacin 400 mg for one day and 48 received fleroxacin 400 mg for two days, were included in the analysis of efficacy. The results showed that fleroxacin was significantly superior to placebo, but that there was no significant difference in terms of efficacy between the one- and two-day regimens. Adverse events, particularly minor neuropsychiatric disturbances such as headache and insomnia, were significantly more common amongst patients receiving active treatment. In conclusion, a single dose of fleroxacin 400 mg could be recommended as self-treatment for visitors to high-risk countries who develop travellers' diarrhoea.
