Acute mastoiditis — the antibiotic era: a multicenter study☆

OBJECTIVES To evaluate the clinical course and identify the causative organisms of acute mastoiditis in a community where most of the patients who develop acute otitis media are treated with antibiotics. METHODS A multicenter retrospective review of a series of 223 consecutive cases of acute mastoiditis. SETTING Nine secondary or tertiary academic or non-academic referral centers. RESULTS Prior to the diagnosis of acute mastoiditis, 121 of the patients (54.3%) had been receiving oral antibiotic treatment for acute otitis media for periods ranging from 1 to 21 days (mean 5.3 days). Samples for bacterial culture were obtained from 152 patients. Cultures were negative in 60 patients. The organisms isolated in the 92 positive cultures were: Streptococcus pneumoniae (15 patients), Streptococcus pyogenes (14 patients), Staphylococcus aureus (13 patients), Staphylococcus coagulase negative (three patients), Pseudomonas aeruginosa (eight patients), Haemophilus influenzae (four patients), Proteus mirabilis (two patients), Escherichia coli (two patients), Klebsiella pneumoniae (one patient), Enterobacter (one patient), Acinetobacter (one patient), anaerobic gram-negative bacilli (one patient), and fungi (two patients). Ten patients had mixed flora. Sixteen patients presented with complications (cerebellar abscess, perisinus empyema, subdural abscess or empyema, extradural abscess, cavernous sinus thrombosis, lateral sinus thrombosis, bacterial meningitis, labyrinthitis, petrositis, or facial nerve palsy). CONCLUSIONS Antibiotic treatment cannot be considered an absolute safeguard against the development of acute mastoiditis. Early myringotomy for acute otitis media seems to decrease the incidence of complications. The distribution of causative organisms in acute mastoiditis differs from that in acute otitis media. Intracranial complications in acute mastoiditis are not rare. Because of the diversity of causative organisms in acute mastoiditis and the growing resistance of bacteria to the various antibiotics, all means to obtain a sample for culture prior to antibiotic treatment, including general anesthesia.

Tracheotomy Complications: A Retrospective Study of 1130 Cases

BACKGROUND: Tracheotomy is one of the most frequently performed surgical procedures in the critically ill patient. It is frequently performed as an elective therapeutic procedure and only rarely as an emergency procedure. Complications occur in 5% to 40% of tracheotomies depending on study design, patient follow-up, and the definition of the different complications. The mortality rate of tracheotomy is less than 2%. Numerous studies demonstrate a greater complication and mortality rate in emergency situations, in severely ill patients, and in small children. METHODS: A retrospective study of 1130 consecutive tracheotomies performed during 1 decade (January 1987 through December 1996) is presented. We studied the indications for surgery, the major complications of tracheotomy, and their treatment and outcome. We also noted the overall mortality rate and the specific complications that led to these deaths. RESULTS: In total, 1130 tracheotomies were performed. Major complications occurred in 49 of the cases, and 8 deaths were directly attributed to the tracheotomy. The most common complication was tracheal stenosis, which occurred in 21 cases. Hemorrhage was the second most common complication, which occurred in 9 cases. CONCLUSION: This is one of the largest series of consecutive tracheotomies compiled. We found a relatively low overall complication and mortality rate compared with other large series. Tracheal stenosis was the most common complication in contrast to other series. Our opinion is that this may reflect tracheal damage originally caused by prolonged intubation before the tracheotomy. We believe that all other complications of tracheotomy may be prevented or minimized by careful surgical technique and postoperative tracheotomy care. (Otolaryngol Head Neck Surg 2000;123:495-500.)

The beverage maté: a risk factor for cancer of the head and neck.

Maté is a tealike beverage consumed habitually in South America and among South Americans throughout the world. It is brewed from the dried leaves and stemlets of the perennial tree Ilex paraguariensis (yerba maté), a species that belongs to the Aquifoliaceae family. Maté consumption has been associated with an increased rate of oral, oropharyngeal, esophageal, and laryngeal cancers. The purpose of this study is to review the literature and discuss the role of Maté consumption as a risk factor for head and neck cancers.

Tracheotomy: Changing indications and a review of 1130 cases

BACKGROUND Tracheotomy is one of the oldest known operations, dating back to ancient Egypt and India some 3000 years ago. The indications for tracheotomy have changed and expanded during the twentieth century. Today, owing to advancements in intensive care and the widespread use of mechanical ventilation, tracheotomy is one of the most commonly performed surgical procedures and is encountered on a regular basis by hospital physicians in all fields. We present one of the largest series of consecutive tracheotomies spanning one decade. We review and discuss the modern indications for tracheotomy and emphasize the changes in these indications over the past century. METHODS A retrospective study of 1,130 consecutive tracheotomies performed over one decade is presented. We studied the indications for surgery, the complications and mortality rate, and the various hospital departments requiring tracheotomies. RESULTS A total of 1,130 tracheotomies were performed: 859 to assist in mechanical ventilation, 124 as an adjunct to head and neck or chest surgery, and 68 to relieve upper airway obstruction. Major complications occurred in 49 of the cases, and there were 8 deaths directly attributed to the tracheotomies. The most common complication was tracheal stenosis, occurring in 21 cases. Hemorrhage was the second most common complication, occurring in 9 cases. CONCLUSION Tracheotomy, once used almost exclusively to bypass upper airway obstruction, is now a very common elective therapeutic procedure used mostly to facilitate prolonged intubation and ventilation of the critically ill. Today tracheotomy is not and should not be an emergency procedure owing to the huge complication and mortality rate of emergency tracheotomy and the existence of alternative routes to obtain immediate airway control in the acutely obstructed upper airway.

Paper patching for chronic tympanic membrane perforations.

OBJECTIVE This study was designed to evaluate the results of paper-patch myringoplasty in patients with chronic perforations of the tympanic membrane of different sizes. STUDY DESIGN AND SETTING A retrospective survey of paper-patch myringoplasties performed in a tertiary referral academic medical center on 77 patients with chronic perforations of the eardrum was carried out. Data consisted of the causes of the perforations, time the perforations had been present, their size, number of patch applications, duration of application, and number of successfully closed perforations. RESULTS Closure rate was 63.2%, 43.5%, and 12.5% for small, medium, and large perforations, respectively. Small perforations needed the least number of repeated applications and the least time for closure. CONCLUSIONS AND SIGNIFICANCE Paper patching is technically simple, time saving, safe to perform, cost effective, and suitable as an outpatient procedure and has a good success rate, It should be tried in perforations smaller than 5 mm before a patient is referred for surgery.

EFFECTS OF MIDDLE EAR EFFUSION ON THE VESTIBULAR SYSTEM IN CHILDREN

Vertigo and dizziness are not common in childhood, but are probably present more often than was formerly thought. These symptoms caused mainly by otitis media and middle ear effusion, two of the most common diseases in children, have been neglected for a long time, both in the literature and in practice, until recently. The purpose of this study was to determine objectively the incidence of balance-related symptoms in children with long-lasting middle ear effusion and to discover whether these symptoms resolve after the insertion of ventilation tubes. One hundred thirty-six children, ages 4 to 9 years, were given electronystagmographic tests and the Bruininks-Oseretsky tests for motor proficiency before and after tube ventilation of the middle ear. The results were compared with those in 74 healthy children with no history of middle ear diseases. Pathologic findings were found in 58% of the children with chronic middle ear effusion, as compared with only 4% of the control group. The symptoms and signs of balance disturbances resolved in 96% of the children after ventilation tube insertion. The results of this study indicate that balance-related symptoms often encountered in young children may result from chronic middle ear effusion and that these symptoms will resolve after evacuation of the effusion and ventilation of the middle ear.

The epiglottis and obstructive sleep apnoea syndrome

Obstructive sleep apnoea syndrome (OSAS) is caused by obstruction or narrowing of the airway at various levels. The repair of one site only will not alleviate the syndrome if there are obstructions in other sites. Epiglottis prolapse during inspiration is an unusual cause of airway obstruction and a rare cause of OSA. Twelve cases of OSAS due to an abnormal epiglottis are presented. We present our approach to the diagnosis using fibre-optic examination of the hypopharynx, and our treatment using endoscopic carbon dioxide laser partial epiglottidectomy. We found in our series that in 11.5 per cent of patients who failed the uvulopalatopharyngoplasty procedure, the reason was a narrow airway at the hypopharyngeal level caused by an abnormal epiglottis. It is our suggestion that in these cases a laser partial epiglottidectomy should be performed. The results of this study show that partial epiglottidectomy can increase the cure rate of patients with obstructive sleep apnoea syndrome by 10-15 per cent.

VENTILATION TUBES AND PERSISTING TYMPANIC MEMBRANE PERFORATIONS

Surgical management of otitis media with effusion and recurrent acute otitis media includes myringotomy and the use of ventilation tubes. Since this procedure was reintroduced by Armstrong in 1954, it has become one of the most commonly performed operations in otolaryngology. In most series perforation of the tympanic membrane in some patients has been reported after spontaneous extrusion or removal of the tympanostomy tubes. We present a retrospective review designed to examine the incidence of persisting perforations of the tympanic membrane in our series of 2604 operated ears. The study also identifies and analyzes the variables and the contributing risk factors. Perforations occurred in 3.06% of the ears: with a greater incidence in children younger than 5 years, when the indication was recurrent purulent otitis media, with the use of long-term Goode T tubes, in cases with repeated insertions of ventilation tubes, and in cases in which postoperative otorrhea was frequent.

Magnesium: a new therapy for idiopathic sudden sensorineural hearing loss.

Objective To determine whether treatment with Mg2+ improves the outcome of idiopathic sudden hearing loss and to investigate which variables influence its prognosis. Study Design Prospective randomized study. Setting Department of Otolaryngology–Head and Neck Surgery, Rambam Medical Center, Haifa, Israel. Patients The study group included 133 patients. Sixty patients were treated with carbogen inhalation, and 73 were treated with a combination of carbogen inhalation and intravenous MgSO4. Results The mean improvement rate was 66.4% in the Mg2+ group and 49.9% in the carbogen group (p < 0.01). Recovery was achieved in 35 patients (48%) in the Mg2+ group and only in 19 patients (31.6%) in the carbogen group (p < 0.01). Significant improvement was seen in 20 patients (27.4%) in the Mg2+ group and in 14 patients (23.3%) in the carbogen group. Partial improvement was seen in eight patients (10.9%) in the Mg2+ group and in 12 patients (20%) in the carbogen group. No improvement was achieved in 10 patients (13.6%) in the Mg2+ group and in 15 patients (25%) in the carbogen group. Patients with vestibular symptoms had a poorer hearing outcome compared to those without vertigo (p < 0.04). Patients who commenced the treatment 8 days or more after onset had poorer recovery as compared with those who started treatment earlier (p < 0.03), regardless of the treatment regimen. Age, sex, and tinnitus had no significant impact on hearing recovery. Conclusion We found that Mg2+ improved hearing recovery in cases of idiopathic sudden hearing loss. Vertigo and treatment delay beyond 8 days were poor prognostic factors for recovery.

Effect of middle ear effusion on the vestibular labyrinth

Although middle ear effusion was once described as the most common cause of vestibular disturbance in children, the association between glue ear and symptoms of dysequilibrium has never been quantified objectively. In this study the effect of middle ear effusion on the vestibular system of the inner ear was studied in a select group of children suffering from long lasting effusion in the middle ear with no evidence of infection at least one year prior to the study. The results were compared with results obtained from otitis free children, as well as from examinations of children after the insertion of ventilating tubes. The results of this study confirm the assumption that middle ear effusion has an adverse effect on the vestibular system, which can be resolved following the insertion of ventilation tubes. This effect may also contribute to the adverse effect that otitis media has on a childs development.
