Vocal fold paresis (VFP) is a relatively common and often overlooked condition that can be difficult to diagnose based on the laryngeal examination alone. A retrospective review of the records of 50 consecutive adult patients with VFP was performed. In each case, the diagnosis of VFP was confirmed by laryngeal electromyography. The presenting symptoms were dysphonia (100%), vocal fatigue (76%), diplophonia (40%), and odynophonia (12%), and the findings were unilateral vocal fold hypomobility (50%), unilateral bowing (36%), and bilateral bowing (22%). Laryngoplasty and/or lipoinjection was performed in 54% of the subjects, and significant vocal improvement was achieved in 85%. VFP appears to be underdiagnosed because many VFP patients have compensatory hyperkinetic disorders at presentation. Although the diagnosis of VFP may be suspected based on the patient's symptoms and findings, the diagnostic sine qua non is laryngeal electromyography. In addition, surgical treatment for VFP appears to be safe and effective.

Dysphonia is a common presenting symptom in cases referred for otolaryngologic evaluation. Similarly, primary care physicians frequently see adolescents or young adults with symptomatic Epstein-Barr virus infection. Some of the patients with active Epstein-Barr virus infection who have severe clinical manifestations of infectious mononucleosis will be referred for otolaryngologic evaluation. Voice abnormalities in these patients, though, are usually limited to altered resonance due to pharyngeal crowding by hyperplastic lymphoid tissue. We describe a patient with infectious mononucleosis who was referred for evaluation of dysphonia and was diagnosed with unilateral tongue and vocal fold paresis. We also discuss the patient's clinical course and review the related literature. Although uncommon, cranial nerve palsies must be considered in the patient with Epstein-Barr virus infection who presents with voice or speech disturbance.

Fourteen patients with severe neuroparalytic snake envenomation, resulting in acute type II respiratory failure, admitted to respiratory critical care unit for mechanical ventilation during one year period, were studied. Ventilatory requirements, amount of anti snake venom (ASV) infused, period of neurological recovery and hospital survival were evaluated. All patients had severe manifestations such as ptosis, extraocular muscle paresis and limb weakness along with dyspnoea. Seven patients (50%) had additional complaints of dysphagia and dysphonia. ASV was administered to all, with a median requirement of 900 ml. Mechanical ventilation was required for a median duration of 17 hours and all except one patient, who had suffered irreversible hypoxic cerebral injury prior to resuscitation, survived with complete neurological recovery. We conclude, that the timely institution of ventilatory support and anti-venom therapy in such patients, is associated with an excellent outcome.

Congenital cervical teratomas are associated with a high rate of perinatal mortality due to airway obstruction. We describe a multidisciplinary management of a neonate with prenatal diagnosis of giant cervical teratoma. An 'operation on placenta support' (OOPS) technique was carried out during delivery, and intubation was successfully performed with no perinatal anoxic damage. Postnatal computed tomography and angiography showed a huge teratoma covering both sides of the neck with agenesis of the big blood vessels on the left side. A rapidly developing third space phenomenon and deterioration in the general status of the neonate, required early surgical intervention. During surgical excision, the left carotid artery and internal jugular vein, the left lobe of the thyroid gland and the left recurrent laryngeal nerve were not detected. The left vagus, accessory and hypoglossal nerves were positioned between the skin and the tumor, at a distance from their normal anatomical location. Pathologic examination confirmed the diagnosis indicating immature teratoma with no signs of malignancy. The postoperative period was complicated by neurological deterioration, pharyngo-cutaneous fistula and paresis of the left hypoglossal nerve. However, all the symptoms resolved spontaneously. Tracheotomy was performed when the baby was 6 weeks old due to paralysis of the left vocal cord and to severe laryngo-tracheomalacia. She was decannulated when she was 3 years old. Today, she is suffering only from dysphonia. This report confirms the efficacy of a multidisciplinary team-approach and the usefulness of the OOPS technique in prenatally diagnosed cervical masses. It emphasizes the extraordinary characteristics of this case, mainly the development of a third space phenomenon and the unusual surgical findings.

Swallowing difficulties and dysphonia may occur in patients undergoing anterior cervical discectomy and fusion. The etiology and incidence of these abnormalities, however, are not well defined. In view of this, we performed a prospective, objective analysis of swallowing function and vocal cord approximation in patients undergoing anterior cervical discectomy and fusion. Twenty-three consecutive patients (22 male and one female, mean age 59 years) undergoing anterior cervical discectomy and fusion had standardized modified barium swallow study and videolaryngoendoscopy performed preoperatively and again at 1 week and 1 month postoperatively. Eleven patients (48%) had radiographic evidence of preoperative swallowing abnormalities. The majority of these patients had myelopathic rather than radicular findings (p = 0.03). None, however, had symptoms of swallowing dysfunction. Among these patients, one had worse function postoperatively, three had improvement, and function remained unchanged in seven. The preoperative swallowing assessment was normal in 12 patients (52%). Postoperative radiographic swallowing abnormalities were demonstrated in eight of these patients (67%). Preoperative vocal cord movement was normal in all patients. Postoperatively, vocal cord paresis was detected in two patients. The paresis was transient in one and permanent in the other. Age, previous medical history, operation duration, and spinal level decompressed were not significantly associated with the incidence of swallowing dysfunction. There was, however, a tendency for patients undergoing multilevel surgery to demonstrate an increased incidence of swallowing abnormalities on postoperative radiographic studies. In addition, soft tissue swelling was more frequent in patients whose swallowing function was worse postoperatively (p = 0.007). Postoperative voice and swallowing dysfunction are common complications of anterior cervical discectomy and fusion, although in the majority of patients these abnormalities are not symptomatic. Patients undergoing multilevel procedures are at an increased risk for these complications, in part because of soft tissue swelling in the neck.

The Phonosurgery Committee of the European Laryngological Society (ELS) has examined the definition and technical description of phonosurgical procedures. Based on this review, the committee has proposed a working classification. The current presentation is restricted to vocal fold surgery (VFS) with phonosurgical intent. Both the pathology and the therapeutic aim define VFS: (1). vocal fold lesions that impair vibratory movements require excision (e.g., vocal fold nodule), incision and suction (e.g., Reinke's edema), dissection and/or augmentation (e.g., sulcus-vergeture), coagulation or vaporization (e.g., varicosity) and incision and stenting (e.g., glottal web); (2.vocal fold movement disorders require position and/or tension correction by augmentation (e.g., vocal fold paresis), injection (e.g., botulinum toxin for spasmodic dysphonia) and excision (e.g., dysphonia plicae ventricularis). This presentation excludes surgical instrumentation, implants or injectable materials. Being essentially surgeon-dependent, usage may vary over time and with experience.

Gore-Tex has been used as an effective implant for medialization laryngoplasty in the management of paralytic dysphonia; however, reporting of large patient cohorts has been limited. Furthermore, the use of Gore-Tex in the treatment of glottal incompetence secondary to soft tissue defects has not yet been described. Finally, a number of the procedural nuances of using Gore-Tex have not been elucidated. A prospective investigation was done on 142 patients who underwent 152 Gore-Tex medialization laryngoplasties in 183 vocal folds from December 1997 to March 2002. The primary diagnoses prompting the 152 procedures were paralysis in 94, paresis in 18, cancer reconstruction in 14, sulcus vocalis in 6, atrophy in 3, trauma defect in 5, arytenoid dislocation in 3, bilateral paralysis in 3, bilateral paresis in 1, parkinsonism in 4, and neurologic aerodynamic dissociation in 1. One patient who underwent reconstruction of a complex cancer defect required endoscopic removal of the Gore-Tex because of persistent granulation. Clinical observations reveal that Gore-Tex is a versatile implant that is ideally suited for phonosurgical reconstruction of aerodynamic glottal incompetence secondary to a variety of causes. Gore-Tex was especially useful for medialization of complex anatomic soft tissue defects such as those resulting from cancer resection, trauma, atrophy, and sulcus vocalis. There was superior ease in handling, placement, and in vivo adjustability.

The botulinum A toxin inhibits the release of acethylcoline from the vesicles of presynaptic neuronal end plates. Its effect is a transient pharmacological neurectomy. The toxin is used more and more widespreadingly. It selectively inhibits certain muscles or groups of muscles. Its use is of outstanding importance in the treatment of blepharospasm, a disease possibly causing transient functional blindness. This blindness develops randomly, with undetermined duration, therefore it may even threaten the life of the patient. There is no alternative treatment. In ophthalmology, the toxin is used in the therapy of strabismus and nystagmus, as well as replacing entropion operations. Most often its use is suggested in the treatment of focal dystonies, dysphonia, tremor palatinus, dysphagia, spasm of the oesophagus sphincter muscle, nasal hypersecretion, hemifacial spasm, headaches, focal hyperhydrosis, proctalgia fugax, diabetic gastroparesis and difficulties in urination. In the past few years, the toxin has been used for esthetic reasons as well. By relaxing the muscles causing wrinkles, non-permanent result may be reached with its use. The botulinum A toxin does not have general side effects. As local side effects, haematomas and unwanted, transient paresis of the neighboring muscles can be mentioned.

The observation of the glottis and the vocal fold mobility during phonation enables the diagnosis of larynx pathology. Videolaryngostroboscopy (VLSS) facilitates acquiring a precise endoscopic picture and an evaluation of the vocal fold vibratory movements. This method is recognised as an objective, repetitive and non-invasive approach to accelerate early diagnosis in laryngeal carcinoma, vocal nodules, vocal fold paresis, larynx oedema, functional dysphonia and presbyphonia. The mucosal wave is a particularly important parameter in the stroboscopic examination. The absence of mucosal wave indicates microinfiltrations in the T1 stage of glottic carcinoma and vocal hard nodules, the complete form of paretic dysphonia and the severe form of atrophic presbyphonia. The recurrent mucosal wave suggests re-innervation in the paretic dysphonia. Aberrations in the vocal fold vibrations indicate a supraepithelial oedema of the laryngeal mucosa and a functional type of dysphonia, requiring differential therapy. The larynx image recorded on a video tape is a valuable diagnostic evidence that allows monitoring of therapeutic effects and phoniatric rehabilitation.

Psychogenic dysphonia refers to loss of voice where there is insufficient structural or neurological pathology to account for the nature and severity of the dysphonia, and where loss of volitional control over phonation seems to be related to psychological processes such as anxiety, depression, conversion reaction, or personality disorder. Such dysphonias may often develop post-viral infection with laryngitis, and generally in close proximity to emotionally or psychologically taxing experiences, where "conflict over speaking out" is an issue. In more rare instances, severe and persistent psychogenic dysphonia may develop under innocuous or unrelated circumstances, but over time, it may be traced back to traumatic stress experiences that occurred many months or years prior to the onset of the voice disorder. In such cases, the qualitative nature of the traumatic experience may be reflected in the way the psychogenic voice disorder presents. The possible relationship between psychogenic dysphonia and earlier traumatic stress experience is discussed, and the reportedly low prevalence of conversion reaction (4% to 5%) as the basis for psychogenic dysphonia is challenged. Two cases are presented to illustrate the issues raised: the first, a young woman who was sexually assaulted and chose to "keep her secret," and the second, a 52-year-old woman who developed a psychogenic dysphonia following a second, modified thyroplasty for a unilateral vocal fold paresis.
