Based on the experimental results of thyroplasty, thyroplasty type I which aims at medical shifting the vocal cord was performed on 8 patients with dysphonia, 6 with vocal cord paralysis and 2 with vocal cord atrophy. The surgery was conducted on either in- or out-patient basis and local anesthesia was used. Usually, a rectangular incision was made on the thyroid cartilage at the level of the vocal cord, and the fragmemt was depressed inward. A cartilage piece taken from the opposite side was used as a wedge, if necessary, to enhance the effect of lateral compression of the vocal cord. The voice after surgery was generally satisfactory, except in one case of traumatic vocal cord paralysis. Complications such as stridor or dyspnea were nil. As surgical intervention inside the thyroid cartilage is minimal, fine and reliable adjustment of depression is possible during the surgery.

We have obtained physiologic and psychiatric evaluations on five subjects with episodic laryngeal dyskinesia (LD) and compared them with three patients with expiratory laryngeal stridor and asthma (ELS), and five with chronic asthma (CA). Laryngoscopy confirmed adduction of the vocal cords. Diminished inspiratory flow rates with an expiratory/inspiratory ratio of 1.5 to 3.3 was demonstrated by flow volume studies. Flows improved strikingly while breathing an 80 percent helium/20 percent oxygen mixture. Patients with LD showed varying degrees of depression and sought some form of secondary gain. A histrionic personality, conversion or factitious disorders are not an essential part of this syndrome. Tracheostomy may seldom be necessary in the managing of the acute crisis of LD. Reassurance, oxygen, intermittent positive pressure, and sedation may be sufficient. Mildly depressed patients decreased the frequency and severity of wheezing episodes after receiving reassurance and a clear explanation of ventilatory mechanics.

Two groups of 100 children each who underwent adenoidectomy and/or tonsillectomy were anaesthetised by halothane 1% or by a neuroleptic technique (NLA) using fentanyl 0.0025 mg/kg and droperidol 0.125 mg/kg as a fixed combination (Thalamonal). Both techniques were supplemented with nitrous oxide/oxygen 4/2 l. All children were premedicated with atropine 0.015 mg/kg, fentanyl 0.0025 mg/kg and droperidol 0.125 mg/kg i.m. Quality of premedication and postoperative behaviour and analgesia were assessed by standardised criteria. 93% of the patients arrived at the theatre sleeping or detached, 75% showed almost no reactions to venipuncture. Heart rate during surgery in both groups increased by 13%, mean arterial blood pressure in the NLA group increased by 9% and in the halothane group dropped by 5%. Postoperatively blood pressure in NLA patients returned to normal, while in the halothane group there was a transient rise by 10%. Protective reflexes and consciousness were restored in the NLA group earlier. After halothane, stridor occurred in eight cases upon extubation. Postoperative analgesia scores in NLA patients were double those in the halothane group. Moderate metabolic acidosis and slight hypercapnia were postoperatively present in both groups twice. Modified neuroleptanaesthesia proved equal to halothane anaesthesia for ENT surgery. No respiratory depression was seen. Advantages like uncomplicated quick recovery and protracted postoperative analgesia are opposed by disadvantages like inferior vegetative blockade and inferior pharmacokinetics. Close postoperative supervision in a recovery room is a prerequisite to using this NLA technique.

Clonidine hydrochloride (CH) is an antihypertensive drug with complex pharmacologic activity including central and peripheral alpha-adrenergic stimulation and CNS depression. We reviewed the records of 5 children admitted to our Pediatric Intensive Care Unit following accidental ingestion of CH. All patients presented with lethargy or stupor, beginning 20-60 minutes after ingestion. Respiratory depression or apnea occurred in 4, requiring endotracheal intubation in 2 and mechanical ventilation in 1. All 5 developed mild to moderate hypertension, and 3 developed asymptomatic bradycardia. The dose of CH ingested was estimated to be 0.2-0.4 mg in 4 out of 5 patients. Treatment consisted of efforts to prevent absorption of CH from the GI tract and supportive care. All signs of CH toxicity resolved within 6-14 hours. Four patients were transferred from ICU within 24 hours and discharged home the following day. One patient developed post-extubation stridor and atelectasis. Significant toxicity occurred even though the amount of CH ingested was relatively small in at least 4 or 5 patients. Transient hypertension occurred early in the hospital course of all patients and resolved without treatment. Hypotension and symptomatic bradycardia were not observed. Apnea was the most serious abnormality observed. All patients recovered without significant morbidity.

Two cases of non-fatal airway obstruction by nasal secretions are described. The diagnosis was made after laryngoscopy and the features which suggested this previously undescribed aetiology were: depression of conscious level; poor oral hygiene; and irregular friable mass with mucoid areas obstructing the airway. The diagnosis was confirmed by histological examination of the obstructing material which was composed of laminated fragments of squamous epithelium, keratin debris and mucus. It is suggested that these masses form in the post-nasal space and then become dislodged descending into the larynx, where they cause partial laryngeal obstruction and stridor. In patients whose conscious level is depressed and who have poor oral hygiene, nasal secretions should be considered as a cause of sudden unexplained airway obstruction and stridor.

A five year retrospective review of all exposures to a high concentration phenol disinfectant (Creolin Disinfectant 26% phenol) reported to a regional poison center located 96 cases, with 16 cases lost to follow up. There were 60 oral-only exposures, 7 dermal-only exposures and 12 oral/dermal exposure. One patient was an inhalation exposure. Fifty-two cases (65%) were evaluated in a hospital. Eleven patients with oral exposures (14%) experienced rapid CNS depression, but no seizures occurred. Vomiting, coughing, and stridor was noted in 14, 7 and 4 patients respectively. Burns were noted in 17 of 72 (24%) patients with oral exposure and 5 of 19 (26%) with dermal exposure. Seventeen patients underwent endoscopy. Tissue sloughing was noted in one case. All other burns were first degree. No cardiovascular complications occurred. Twenty-eight patients (35%) were followed at home via telephone with one episode of vomiting and one episode of dermal irritation occurring. CNS toxicity from exposure to a high concentration phenol containing cleaning product appears to be rapid in onset. The absence of serious toxicity and major chemical burns in this series does not eliminate concern with the corrosive and systemic risks of phenol poisoning.

Gastroesophageal reflux and pulmonary disease have become causally associated owing to reports of improved pulmonary function in patients with asthma or stridor following antireflux pharmacotherapy or surgery. Mechanisms by which reflux causes pulmonary disease include direct aspiration and neural reflex arcs. A novel additional mechanism for acute life-threatening episodes implicates increased beta-endorphin levels resulting from acid-mediated esophageal pain in the depression of respiratory drive. Diagnostic modalities used in the evaluation of reflux have often been inadequate to demonstrate a cause-and-effect relationship between reflux and pulmonary disease. Recent studies using multiple site pH-metry have attempted to provide evidence for cause and effect but have achieved mixed results. Aggressive antireflux pharmacotherapy and, sometimes, surgery help those patients with chronic pulmonary disease mediated by gastroesophageal reflux.

The most important complications from tonsillectomy and adenoidectomy are bleeding, stridor, and laryngospasm. This controlled, double-blind study was designed to investigate the effects of topical and intravenous lidocaine on stridor and laryngospasm. A total of 134 patients scheduled for elective tonsillectomy and/or adenoidectomy were randomly separated into four groups. In the topical lidocaine group 4 mg/kg of 2% lidocaine was applied to subglottic, glottic, and supraglottic areas before endotracheal intubation. Normal saline solution was used topically for the first control group. In the intravenous lidocaine group, patients were given 1 mg/kg of 2% lidocaine before extubation, and the same amount of 0.9% NaCl was given to the second control group. Postoperative stridor, laryngospasm, cyanosis, bleeding, sedation degree, and respiratory depression were observed, and plasma lidocaine levels were measured. Both topical and intravenous lidocaine groups revealed less stridor and laryngospasm than the control groups, and no difference was found between the topical and intravenous lidocaine groups except the higher sedation scores in the early postoperative period for the intravenous lidocaine group.

Relapsing polychondritis is a rare disorder, that can present initially to Otolaryngologists and can easily be overlooked due to its relative rarity and atypical initial symptoms and signs. Here we report on a 12-year-old schoolboy who presented initially with ear, nose and throat manifestations, including stridor, cough, hoarseness, sore throat and fever. The other clinical signs such as nasal tip, depression and softening of right auricle, developed subsequently. The clinical features, laboratory investigations, diagnostic criteria and treatment options were discussed with a brief review of literature.

Laryngeal dyspnea is a life-threatening emergency situation. The diagnosis is clinical and made from the association of: inspiratory bradypnea, intercostal and sus-sternal inspiratory depression, with or without stridor. The aetiologies are most often laryngeal tumours or inflammatory oedema; incidence of epiglottitis has decreased due to vaccine against Haemophilus influenzae. Airway obstruction due to foreign body includes acute laryngeal dyspnea and reflex paroxysmal coughing without fever. Management of a laryngeal dyspnea depends on the aetiology and the severity of clinical symptoms. Medical treatment associates racemic epinephrine aerosol, steroids, and oxygenation. In the presence of severe dyspnea, intubation after anaesthetising the patient and positive pressure ventilation is required.
