RESUMO

Peritonsillar abscess, a complication of tonsillitis, is not uncommon. The usual treatment consists of needle aspiration or surgical drainage and antibiotic treatment. Tonsillectomy may be used in the management of this condition, either at the time of diagnosis or after an interval period. Severe complications of peritonsillar abscess are rare. Synergistic necrotizing cellulitis is a fulminant infection associated with spread along fascial plains, necrosis of connective tissue and muscle, and high mortality. It is usually otondogenic in origin in the cervicofacial area and occurs in debilitated or immune compromised patients. We discuss cervicofacial-necrotizing soft tissue disease and report an unusual case of extensive synergistic necrotizing cellulitis of the neck, chest, and shoulder as a result of a peritonsillar abscess.

RESUMO

PURPOSE: This study was designed to examine the association between iron-deficiency anemia and the frequency of recurrent acute otitis media in children, and to evaluate the effect of restoring normal hemoglobin levels on the frequency of acute otitis media attacks. MATERIALS AND METHODS: A total of 680 children with frequent episodes of acute otitis media were enrolled in the study. The levels of the hemoglobin were measured in both these children and in 200 healthy children with no history of infections. The correlation between hemoglobin level and the frequency of middle ear infections was studied and analyzed. All children with hemoglobin levels lower than 9.5 g/dL received iron supplementation until they reached a level of at least 11 g/dL, and the subsequent frequency of middle ear infections was recorded. RESULTS: The 680 children had an average of 8.3 +/- 2.7 episodes of acute otitis media per year per child, and an average hemoglobin level of 11.4 +/- 2.7 g/dL, whereas the controls had an average hemoglobin level of 13.1 +/- 2.5 g/dL. Twenty percent had hemoglobin levels below 9.5 g/dL. These children had more episodes of acute otitis media when compared with children with average levels. By increasing the hemoglobin level in these children, the frequency of the episodes of acute otitis media decreased significantly. CONCLUSIONS: This study confirms that anemic children have higher prevalence of episodes of acute otitis media in comparison to healthy, nonanemic children, and shows that there is a direct relationship between the degree of the anemia and the number of the episodes.

RESUMO

PURPOSE: Subjects with noise-induced hearing loss sometimes also complain about balance disorders, but reports of clinical series that give contradictory results are highly controversial. This study was designed to evaluate the effects of intense noise on the vestibular labyrinth, both in subjects with symmetrical hearing loss and in subjects with asymmetrical loss, and to examine the correlation between the subjects' complaints and the results of the vestibular function tests. METHODS: A total of 258 male military personnel, heavily exposed to various intense noises, were included in the study. They were divided into 2 groups according to their hearing; 134 had a symmetrical high-tone hearing loss, and 124 had asymmetrical losses. Each group was divided into 2 subgroups according to the presence or absence of vestibular complaints. All of the subjects underwent a complete audiological and electronystagmographic evaluation. RESULTS: We found that vestibular damage caused by intense noise exposure might be expressed clinically in subjects with asymmetrical hearing loss. There was a strong correlation between the subjects' complaints and the results of the vestibular function tests. There was no correlation between the severity of the hearing loss and the vestibular symptomatology and pathology. CONCLUSIONS: Subjects exposed to intense noise may have evidence of vestibular pathology only when there is an asymmetrical hearing loss. Whenever hearing loss is symmetrical, an equal damage to the vestibular system of both ears is most probably responsible for the absence of abnormal findings on the vestibular function tests. The results of this study have important medicolegal implications for individuals exposed to intense noises.

RESUMO

Denis Burkitt pioneered the association of viruses and cancer in humans with his observations of lymphomatous tumors in children in equatorial Africa. The Epstein-Barr virus (EBV), a human B lymphotrophic herpes virus, is strongly associated with undifferentiated carcinoma of the nasopharynx and African-type Burkitt's lymphoma. More recently, an association of this virus with other epithelial neoplasms, lymphomas, and immunodeficiency-related malignant and nonmalignant conditions has been reported. Since many of these tumors are rare, much of the information is based on sporadic reports and relatively small series of patients. The purpose of this report is to review the literature and examine the growing association of EBV with various head and neck malignancies.

RESUMO

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.

RESUMO

Obstructive sleep apnea (OSA) and laryngomalacia are two different entities. Occasionally, they may have a common etiology: an elongated, flaccid, and lax epiglottis that is displaced posteriorly during inspiration causing airway obstruction. Twenty-seven adults with a diagnosis of airway obstruction or OSA of various degrees, and 12 infants with severe stridor associated with frequent apneas due to laryngomalacia, who on fiberoptic examination were found to have a posteriorly displaced epiglottis, underwent partial epiglottidectomy with a CO2 laser. Their postoperative recovery was uneventful. Polysomnographic studies performed after operation in the adult patients demonstrated statistically significant improvement in 85% of the patients. In all the cases of laryngomalacia, stridor ceased permanently after surgery, together with complete cessation of the apneic episodes. This study demonstrates that similar pathophysiological mechanisms may be involved in both laryngomalacia and in OSA. Effective and relatively safe treatment can be achieved by partial resection of the epiglottis with a microlaryngoscopic CO2 laser.

RESUMO

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.

RESUMO

OBJECTIVE: We present a possible negative side effect of a sudden onset of secretory otitis media in a 12-year-old boy with unilateral cleft lip and palate who underwent maxillary expansion. The secretory otitis media caused a temporary hearing loss developed during the activation of the expander appliance. The possible causes for this complication are discussed. CONCLUSIONS: Clinicians should be aware of the possible association between maxillary expansion and secretory otitis media.

RESUMO

BACKGROUND: Atrophic rhinitis is a distressing and socially crippling disease. Surgical treatment has been used for patients with severe disease that is unresponsive to medical therapy. METHODS: Eight patients with primary atrophic rhinitis were treated surgically by narrowing of the nasal fossae with implantation of 2 Plastipore plates per affected side into submucosal pockets into the floor of the nose and septum, thus reducing the volume of the nasal fossae. RESULTS: Excellent results were obtained in 6 patients, with complete resolution of symptoms and good results and only minor crusting in 2 patients. One implant was extruded spontaneously 18 months after implantation and was reimplanted. Results in this patient before and after reimplantation were excellent. There were no cases of infection and no other complications. CONCLUSION: We implanted Plastipore, a high-density polyethylene sponge with micropores, which enables tissue ingrowth, anchoring the implants to the surrounding tissue. The surgical technique is performed with the patient under local anesthesia and is relatively easy and avoids complicated flap procedures, allogeneic bone harvesting, and the discomfort of nostril closure for prolonged periods.

RESUMO

OBJECTIVE: Arytenoidectomy is indicated in cases of bilateral median vocal cord paralysis (most commonly due to recurrent laryngeal nerve paralysis), ankylosis of the cricoarytenoid joint due to arthritis, and tumours of the arytenoid cartilage. We propose the use of the submucosal approach, to excise the arytenoid cartilage in cases of vocal cord paralysis. We present the surgical technique and review the history and relevant literature, as well as the pros and cons of various surgical techniques for arytenoidectomy. SETTING: Department of Otolaryngology-Head and Neck Surgery, Rambam Medical Center, Haifa, Israel. METHOD: We present six cases: five cases of bilateral vocal cord paralysis and one case of a chondroma of the arytenoid with mechanical fixation of the cord. All patients suffered from dyspnea on mild exertion. An arytenoidectomy using the submucosal approach was performed on all six patients. RESULTS: Airway results were evaluated via fibre-optic videotape laryngoscopy and direct microlaryngoscopy. Voice was evaluated subjectively by the patients and by a speech therapist before and after surgery. Following the surgery, all six patients showed clinical improvement, they no longer suffered from dyspnea at rest or upon mild exertion, and they retained reasonable voice quality. CONCLUSION: The submucosal approach is not difficult to perform and preserves an intact laryngeal mucosa, which prevents the formation of granulation tissue and scarring, which may further obstruct the lumen. The resulting airway is good, with minimal compromise of phonation. We feel that the submucosal approach to arytenoidectomy is an important addition to the arsenal of many surgical techniques for the treatment of bilateral vocal cord paralysis.

RESUMO

BACKGROUND: Squamous cell carcinoma (SCC) of the anterior two thirds of the tongue is the second most common oral cancer, with the lateral border being the most common location. Squamous cell carcinoma of the dorsum of the tongue is exceedingly rare and has been described in the past as a myth or misdiagnosis. The clinical diagnosis of SCC on the dorsum of the tongue is difficult because it may be mimicked by a wide variety of benign and premalignant lesions, including granular cell myoblastoma, erosive lichen planus, medial rhomboid glossitis, and amyloidosis. In this study we re-evaluate the entity of SCC of the dorsum of the tongue. METHODS: We reviewed 5 large series of carcinoma of the tongue, which include accurate documentation of the topographic location of the carcinoma. We also describe 5 cases of SCC of the dorsum of the tongue from our own series of 99 patients with carcinoma of the tongue. RESULTS: In all 6 series, carcinoma of the dorsum of the tongue was present in 3 to 5% of the carcinomas of the tongue. CONCLUSION: Although rare, SCC of the dorsum of the tongue exists and may be mimicked by benign conditions, thus SCC should be suspected when diagnosing lesions of this area of the tongue.

RESUMO

Agenesis of the parotid is a rare entity. It is usually unilateral but bilateral cases have been described as a rare cause of xerostomia. Accessory parotid tissue is also uncommon and is not normally associated with aplasia of the parotid gland. The embryological, histological, clinical and radiological findings of these two entities will be discussed in addition to the report of an obscure case of bilateral parotid agenesis together with bilateral accessory parotid tissue.
