Recurrent adult acute epiglottitis: the role of lingual tonsillectomy

Use of the transoral robotic surgery to treat patients with recurrent lingual tonsillitis

BACKGROUND

This study evaluates the efficacy of lingual tonsil resection by transoral robotic surgery (TORS) in a large group of patients with recurrent lingual tonsillitis (RLT).

METHODS

Eighty-four patients with RLT treated with a lingual tonsil surgical resection using TORS were analyzed in terms of their postoperative results, disease recurrence, postoperative dysphagia, and quality of life.

RESULTS

A reduction of the mean number/year of acute lingual tonsillitis (LT) episodes emerged after surgery (5.17 vs 0.54 events), comparing the mean number of preoperative and postoperative LT episodes, a statistical significance emerged (P = .0001). The postoperative endoscopic evaluation showed 94.1% of patients with absent or poor lymphatic tissue on the tongue base. Evaluation of postoperative dysphagia showed good results with an average score of 85.9 ± 7.5.

CONCLUSION

This article explains how in patients with chronic LT with medical therapy failure and impaired quality of life, TORS could represent a valid therapeutic option.

Chronic non-granulomatous supraglottitis: a rare and difficult disease

OBJECTIVES

To examine chronic non-granulomatous supraglottitis, a rare disorder of uncertain aetiology with few reported cases in the literature.

CASE REPORTS

We describe two cases of chronic non-granulomatous supraglottitis that led to persistent respiratory compromise. Patients underwent extensive investigation that failed to reveal a definitive diagnosis.

CONCLUSION

In patients suffering from chronic inflammation of the supraglottic larynx without evidence of infection, neoplasm or granulomatous disease, many disorders must be ruled out in order to diagnose chronic non-granulomatous supraglottitis, which is a diagnosis of exclusion. We review the literature on this rare entity, discuss current management strategies, and suggest an algorithm for diagnostic investigation.

Therapy Insight: gastroesophageal reflux disease and laryngopharyngeal reflux

Gastroesophageal reflux disease has been increasingly associated with ear, nose and throat signs and symptoms; however, the cause and effect relationship between these two clinical entities is far from established. Many patients initially diagnosed with gastroesophageal reflux disease as the cause of laryngeal signs do not respond either symptomatically or laryngoscopically to aggressive acid suppression, and do not have abnormal esophageal acid exposure as measured by pH monitoring. This has resulted in frustration on the part of both gastroenterologists and ear, nose and throat physicians, and confusion on the part of patients. This review discusses the reasons for this controversy and highlights data that attempt to clarify this complex area.

Supra-oesophageal manifestations of gastro-oesophageal reflux disease

Since the early 1960s, many studies have been published that consider the possible relationship between gastro-oesophageal (acid) reflux (GORD) and various other complaints, including dental erosions, ear, nose and throat problems, chronic cough and asthma. Although a high coincidence of GORD and these supra-oesophageal complaints have been noted, there is no consensus on the pathophysiology and management of such complications. In this article we review the literature published between 1966 and 2000 on this subject. We also analyse the available information on the incidence, pathophysiological mechanisms, diagnostic approach and therapeutic options in the various subgroups of disorders.

Intrapharyngeal distribution of gastric acid refluxate

OBJECTIVES/HYPOTHESIS

Determination of intrapharyngeal distribution of gastric acid refluxate is needed to better understand the pathogenesis of reflux-attributed aerodigestive tract disorders. The aims of the study were to determine intrapharyngeal distribution of gastric acid refluxate and to determine whether this distribution can better differentiate patients from control subjects compared with data obtained from a single hypopharyngeal site.

METHODS

We prospectively studied 10 healthy volunteers, 12 patients with reflux laryngitis, and 15 patients with vasomotor rhinitis using a concurrent dual pharyngeal/dual esophageal pH recording technique. We determined the hypopharyngeal and oropharyngeal pH profile, including number, duration, and distribution of reflux events irrespective of and in correlation with intraesophageal pH profile using four different pH thresholds.

RESULTS

Few drops in pharyngeal pH were found to be true reflux events based on their correlation with esophageal pH events. For the pharyngeal pH threshold criterion of a drop to 4.0 or less, 6 of 12 patients with reflux laryngitis, 5 of 15 patients with vasomotor rhinitis, and 2 of 10 normal control subjects exhibited a total of 25 (range, 1-5) distal pharyngeal acid reflux events. Overall, 34% of these events reached the oropharyngeal pH recording site. Between-group comparison for all levels of pH threshold criteria did not show any significant difference of reflux parameters in the hypopharyngeal or in the oropharyngeal sites among the studied groups.

CONCLUSIONS

Reflux of gastric acid into the pharynx may extend to the region of the oropharynx in both patients and control subjects. Overall distribution of acid refluxate to the oropharynx is low but as groups is similar between healthy individuals and patients with reflux laryngitis and those with vasomotor rhinitis. Parameters of oropharyngeal acid reflux such as number and duration do not differentiate patients from control subjects.

Empiric esomeprazole in the treatment of laryngopharyngeal reflux

OBJECTIVE

Objectives were to determine the efficacy of empiric treatment with esomeprazole for patients diagnosed with laryngopharyngeal reflux and to determine a treatment paradigm for this patient population.

STUDY DESIGN

Prospective study.

METHODS

Patients were treated with a once-daily dose of 40 mg esomeprazole for 8 weeks. All patients completed a subjective symptom scale (rating laryngeal symptoms and esophageal symptoms) and scoring of flexible fiberoptic examination before treatment and at 4 and 8 weeks of treatment. Nonresponders (<50% reduction in symptom score) were recommended to undergo 24-hour dual-probe pH study while on a regimen of 40 mg esomeprazole once a day, to evaluate for the adequacy of acid suppression.

RESULTS

Thirty patients completed the course of therapy. After 4 weeks of treatment, only 8 of 30 patients had significant improvement of their overall symptoms (8 of 30 improved on laryngeal score, and 11 of 18 improved on esophageal score). At 8 weeks of treatment, 19 of 30 patients had significant improvement on their overall symptoms (18 of 30 on laryngeal score, and 13 of 18 on their esophageal score). Five of seven nonresponders who agreed to be tested had positive findings on pH studies (on medication regimen) at 1 cm above the upper esophageal sphincter. Four of 10 nonresponders improved further after increasing their dosage to 40 mg twice a day. Laryngeal examination scores were statistically improved in responders after 8 weeks of treatment.

CONCLUSIONS

Laryngopharyngeal reflux symptoms require at least 8 weeks of treatment for significant improvement in the majority of patients. Esophageal symptoms improve sooner. Nonresponders at a daily dose of 40 mg should be treated with a dosage of 40 mg twice daily, and pH study on medication reserved for nonresponders at this higher dose. Laryngeal examination scores showed mild but statistically significant improvement at 8 weeks of therapy in responders.

Gastroesophageal reflux disease and the larynx

Gastroesophageal reflux disease (GERD) is associated with ear, nose, and throat (ENT) signs and symptoms. Previously, experiments in animal larynx suggested that acid in combination with pepsin resulted in more laryngeal injury than acid alone. Recently, similar experiments expanded on the above observation, finding no laryngeal inflammation with bile acid, trypsin, or combination of bile constituents in alkaline pH values. Combined, experimental evidence highlights the importance of acidic refluxates that contain pepsin and/or bile acids; however, many patients with laryngeal signs suggestive of GERD do not respond to aggressive acid suppression. This has resulted in controversy about the exact nature of relationship between GERD and ENT signs and symptoms. Because the diagnosis is initially suspected after a laryngoscopic examination by the ENT physicians, the suboptimal clinical response may be caused by the poor specificity of this exam in identifying GERD as the cause of patients' laryngeal symptoms. Hence, a multidisciplinary approach is often required in the optimum treatment of these patients.

Association of laryngopharyngeal symptoms with gastroesophageal reflux disease

OBJECTIVES

The prevalence of gastroesophageal reflux disease (GERD) in patients with laryngopharyngeal disorders is probably greater than realized.

STUDY DESIGN

Prospective study.

METHODS

To investigate the incidence of gastroenterological diseases including GERD in patients complaining of nonspecific laryngopharyngeal symptoms, laryngological examinations and gastroenterological evaluation with esophagogastroduodenoscopy were performed in 30 patients who refused to undergo 24-hour pH monitoring. Therapeutic intervention by behavioural and dietary modifications, antireflux medication, and eradication of Helicobacter pylori were assessed for changes in laryngeal findings and relief of symptoms.

RESULTS

Posterior laryngitis was present in 26 patients and in 19 of them was accompanied by erythema and edema of the interarytenoid region. Gastroenterological diseases such as GERD (43%), hiatal hernia (43%), and Helicobacter pylori-positive antrum gastritis (23%) were confirmed in 22 (73%) cases by esophagogastroduodenoscopy and histological examination of biopsy specimens. Medical antireflux treatment and eradication of Helicobacter pylori resulted in a remarkably therapeutic success rate of 90% because there was resolution of laryngopharyngeal symptoms and laryngeal findings in 20 of 22 patients with gastroenterological diseases for the mean follow-up period of 8 months.

CONCLUSIONS

Laryngopharyngeal symptoms can be predictors of gastroesophageal diseases and GERD because the most frequent underlying cause is supposed to be associated with posterior laryngitis. Medical antireflux treatment is effective for relief of symptoms and mucosal healing of posterior laryngitis.

Recurrent acute epiglottitis in adults: defective antibody response

BACKGROUND

Recurrent acute epiglottitis is uncommon in adults. In the medical literature, very little is known about the immune status of this population.

OBJECTIVE

To evaluate the immune system of a group of four adult patients with recurrent acute epiglottitis, in what represents the largest series ever reported.

METHODS

The clinical course of these episodes was carefully evaluated and a basic immune deficiency work-up was carried out for each patient.

RESULTS

All four patients displayed clinical and laboratory evidence of impaired humoral immunity. One patient was splenectomized. Another patient had a below normal immunoglobulin G level. At the time of their first evaluation, none of our patients had specific antibodies against Haemophilus influenzae and one had a subnormal Streptococcus pneumoniae immunoglobulin G level for a majority of serotypes. After specific vaccination, two patients had persistent abnormalities in their response to one or more polysaccharides or conjugate-polysaccharide antigens. In the other two, the transient abnormalities were corrected by immunization.

CONCLUSIONS

When recurrent acute epiglottitis occurs in adults, it is important to investigate the immune system because a quantitative or a specific antibody deficiency could be found. It also follows that these patients will be successfully treated either by immunization or antibody replacement.

Incidence of reflux in young children undergoing adenoidectomy

OBJECTIVE

To compare the incidence of gastroesophageal reflux disease (GERD) in children under 2 years of age who have symptomatic adenoid hypertrophy requiring surgical removal or who have otitis media with effusion requiring ventilation tube insertion without adenoidectomy.

STUDY DESIGN

Retrospective chart review.

SETTING

An academic pediatric otolaryngology unit.

PATIENTS

All children under age 2 undergoing adenoidectomy (Ad group) between January 1998 and May 2000 were compared with children in the same age range having ventilation tube insertion without adenoidectomy (VT group).

MAIN OUTCOME MEASURES

Whether a diagnosis of GERD was made, how it was made, GERD treatment, and resolution of symptoms were compared.

RESULTS

There were 95 children in the Ad group and 99 in the VT group. GERD incidence was significantly higher in the Ad group where it was 42% versus 7% in the VT group (P < .001). In the Ad group, 88% of children age 1 or less had GERD, and 32% of those older than 1 had GERD diagnosed. In the VT group, 14% of patients age 1 or less and 2% of those older than 1 had a diagnosis of GERD.

CONCLUSIONS

Children under age 2 with symptomatic adenoid enlargement requiring adenoidectomy have a significantly higher incidence of GERD than children in the same age group presenting with otitis media requiring ventilation tube insertion.

Acute epiglottitis in adults: the Royal Melbourne Hospital experience

BACKGROUND

To examine the common presentations and management of acute epiglottitis in adults.

METHOD

Retrospective clinical study of 17 consecutive adult patients who presented to the Royal Melbourne Hospital between January 1988 and December 2000 was undertaken.

RESULTS

The mean patient age was 47 years (range 20-87 years) and the male-to-female ratio was 1.8 : 1.0. Peak incidence occurred in September during early spring. All patients presented with sore throat and dysphagia; however, respiratory distress was only noted in 65%. The most common signs were temperature and tachycardia. Four patients (23%) required endotracheal intubation, which was performed electively in three and as an emergency in one. Three of 14 blood cultures were positive, two yielded Haemophilus influenzae type b and one yielded Streptococcus mitis. One of the four throat cultures was positive for Haemophilus influenzae type b. Twelve patients underwent awake flexible laryngoscopy under topical anaesthetic as part of their initial assessment, and there were no complications associated with this procedure. There was no mortality.

CONCLUSIONS

The diagnosis of acute epiglottitis in the adult population is difficult as respiratory distress may be absent. Patients who have a significant sore throat with no obvious aetiology should have direct visualization of their larynx by flexible laryngoscopy. Lateral X-ray of neck is of limited value. Once diagnosed, these patients should be hospitalized and monitored as airway obstruction may develop rapidly.

Asymptomatic lingual tonsillar hypertrophy and difficult airway management: a report of three cases

PURPOSE

To report on the airway management of three cases of asymptomatic lingual tonsillar hypertrophy (LTH).

MATERIAL

On three separate occasions, patients presenting for elective surgery were subsequently found to have asymptomatic LTH. In all cases preoperative airway examination was essentially unremarkable and no unusual difficulties were anticipated. In the first case, despite an inability to visualize the glottic opening, the patient was intubated successfully on the initial attempt and had no further problems in the perioperative period. In the second case, neither direct laryngoscopy, utilizing the MacIntosh and McCoy blades, nor fibreoptic visualization enabled successful intubation. Ventilation was maintained with a laryngeal mask airway (LMA) until the anesthetic was reversible. Upon awakening and removal of the LMA, the patient totally obstructed and could not be ventilated, necessitating emergency cricothyroidotomy. The third patient was an elderly gentleman in whom successful intubation was eventually achieved, with considerable difficulty, by the otorhinolaryngologist (ENT surgeon) utilizing a straight blade. On a second occasion, he was again intubated by the same ENT surgeon, this time utilizing the anterior commissure blade. All three patients were subsequently discharged without further sequelae.

CONCLUSION

Asymptomatic LTH can cause varying degrees of unexpected difficulty in securing the airway and, at present, no single method will necessarily improve the chances of successful intubation. Therefore, strategies to manage unanticipated difficult intubation secondary to supraglottic airway pathology need to be performed and practiced, including the establishment of a transtracheal airway.

Effect of aggressive therapy on laryngeal symptoms and voice characteristics in patients with gastroesophageal reflux

Gastroesophageal reflux (GER) is associated with a variety of laryngopharyngeal signs and symptoms. Injury of the laryngopharynx as a result of GER can be refractory to conventional antireflux therapy. This prospective study was undertaken to evaluate the prevalence of laryngopharyngeal signs and symptoms in patients with documented GER and to assess the response to a high-dose combination antireflux therapy consisting of cisapride and pantoprazole. Twenty-two patients with symptoms of GER were enrolled. After baseline evaluation using a history questionnaire for symptoms, laryngeal endoscopy and vocal acoustic analysis, patients were started on treatment consisting of pantoprazole 40 mg b.d. and cisapride 20 mg twice daily. Repeat history and otolaryngologic evaluation was performed at 4 weeks. Laryngopharyngeal symptoms were frequent in most patients, with throat clearing and globus being the most prevalent symptoms followed by vocal fatigue and excess mucus production. Almost 90% of the patients had abnormal endoscopic laryngeal findings but the acoustic parameters did not show any abnormal results except for mild elevation in the shimmer. After treatment, all symptoms and endoscopic abnormalities improved significantly except for intermittent dysphonia and laryngeal mucosal redness. Acoustic abnormalities did not change significantly following therapy. Laryngeal symptoms and voice abnormalities are highly prevalent in patients with GER. Combination antireflux therapy with a proton pump inhibitor and a prokinetic agent results in rapid symptomatic and endoscopic response in the majority of patients.

Symptoms, laryngeal findings, and 24-hour pH monitoring in patients with suspected gastroesophago-pharyngeal reflux

OBJECTIVES

To investigate the laryngeal signs and symptoms associated with gastroesophago-pharyngeal reflux (GEPR).

STUDY DESIGN

A prospective controlled study.

METHODS

Nineteen healthy control subjects and 43 patients, 26 with posterior laryngitis (PL) and 17 with a normal larynx and suspected GEPR, were examined using videolaryngoscopy and 24-hour ambulatory dual-probe pH monitoring.

RESULTS

Pharyngeal acid reflux occurred in 18 (69%) patients with PL, in 9 (53%) patients with a normal larynx, and in 5 (26%) healthy control subjects. Multiple-comparison procedure showed that pharyngeal reflux was significantly more prevalent in patients with PL than in the healthy control subjects (P < .05). The laryngoscopic findings in patients with pharyngeal reflux varied from normal mucosa to thickening or edema of the posterior wall of the glottis, which was the most frequent finding in the PL group. Erythema was uncommon; it was found only in patients with verified pharyngeal reflux. There was no difference in symptom profile between the patients with PL and patients with a normal larynx or patients with or without pharyngeal reflux.

CONCLUSIONS

Pharyngeal reflux is significantly more prevalent in patients with posterior laryngitis than in healthy control subjects. Moreover, a certain degree of pharyngeal reflux appears to be a normal phenomenon. The most common laryngeal finding in patients with posterior laryngitis is thickening or edema of the posterior wall of the glottis. GEPR does not yield specific laryngeal symptoms. Thus, it is unreliable to base the reflux diagnosis on symptoms alone.

Lansoprazole treatment of patients with chronic idiopathic laryngitis: a placebo-controlled trial

OBJECTIVE

Previous uncontrolled studies suggested a therapeutic benefit for treating gastroesophageal reflux disease (GERD) among patients with laryngitis. The present study is the first randomized, placebo-controlled, double-blind study of gastric acid suppression among patients with laryngitis in the United States.

METHODS

Patients diagnosed with idiopathic chronic laryngitis were randomized to receive either lansoprazole 30 mg p.o. b.i.d. or a matching placebo for 3 months. Before randomization, all patients underwent upper endoscopy, dual probe ambulatory 24-h esophageal pH-metry, and laryngoscopy, as well as completing a symptom questionnaire for GERD and laryngitis. The primary outcome of treatment was the complete resolution of laryngeal symptoms.

RESULTS

A total of 22 patients with symptoms and signs of chronic laryngitis were enrolled, 20 of whom completed the study. At baseline, there were no significant differences between the two groups with regards to GERD symptoms, erosive esophagitis, proximal and distal esophageal pH-metry, or laryngeal signs and symptoms. In an intention-to-treat analysis, six patients in the lansoprazole group (50%) and only one patient (10%) in the placebo group achieved a complete symptomatic response, p = 0.04. Apart from receiving lansoprazole, there were no significant differences between responders and nonresponders in any of baseline esophageal or laryngeal signs and symptoms.

CONCLUSIONS

Empirical treatment with lansoprazole is efficacious in relieving symptoms of laryngitis compared to placebo. Such treatment can be considered as a first-line option in managing patients with idiopathic chronic laryngitis.

Correlation of findings on direct laryngoscopy and bronchoscopy with presence of extraesophageal reflux disease

OBJECTIVE

To determine the correlation between findings at direct laryngoscopy and bronchoscopy and presence of extraesophageal reflux disease (EERD).

STUDY DESIGN

Retrospective chart review

METHODS

Operative notes of 155 children undergoing direct laryngoscopy and bronchoscopy between 1996 and 1999 for airway symptoms for whom there was a suspicion of EERD were examined. Gastroesophageal reflux disease (GERD) was considered present if at least one test was positive (including upper GI series, pH probe, gastric scintiscan, or esophageal biopsy).

RESULTS

A total of 130 (84%) patients had GERD diagnosed. Ninety percent had at least one laryngotracheal abnormality: 83% had an abnormal larynx and 66% had an abnormal trachea. Laryngeal abnormalities in GERD included postglottic edema, 69%; arytenoid edema, 30%; large lingual tonsil, 16%; vocal fold edema, 12%; vocal fold nodule, 12%; ventricular obliteration, 5%; and hypopharyngeal cobblestoning, 3%. Tracheobronchial abnormalities in GERD included tracheal cobblestoning, 33%; blunting of carina, 12.5%; subglottic stenosis, 11%; increased secretions, 11%; and generalized edema or erythema, 5%. The best sensitivity or specificity was obtained by combining postglottic edema, arytenoid edema, and vocal fold edema, resulting in a sensitivity of 75% and a specificity of 67%. Positive predictive value was 100% for the combination of postglottic edema and any vocal fold or ventricular abnormality.

CONCLUSION

Laryngoscopy and bronchoscopy can reveal findings with a high positive predictive value for the presence of GERD. Endoscopy of the upper airway in children with clinical signs and symptoms of EERD is a promising tool for diagnosis.

Lingual tonsillectomy for refractory paroxysmal cough

Historically, the lingual tonsils are the most neglected members of Waldeyer's ring. They are often overlooked even in a thorough head and neck exam because of their anatomic location and the ambiguous constellation of symptoms which they produce when they are diseased or enlarged. The lingual tonsils have been reported to be associated with a variety of upper aerodigestive tract symptoms including odynophagia, dysphagia, otalgia, globus, halitosis, chronic cough, and dyspnea. Many patients with lingual tonsillar pathology may undergo extensive work-up for some of these non-specific upper airway complaints by their primary physician before referral to an otolaryngologist. Consequently, the diagnosis of lingual tonsillar disease requires a high index of suspicion and a thorough physical exam including evaluation of the tongue base and hypophaynx with indirect mirror or fiberoptic exam. In order to draw attention to this frequently unrecognized entity, we present a case report of a child with chronic cough resulting from lingual tonsillar hypertrophy.

High incidence of laryngopharyngeal reflux in patients with head and neck cancer

OBJECTIVES

Laryngopharyngeal reflux may play a role in the etiology of squamous cell cancer of the head and neck and contribute to complications in head and neck cancer patients after surgery or during radiotherapy.

STUDY DESIGN

Prospective study.

METHODS

To investigate the incidence of laryngopharyngeal and gastroesophageal reflux in patients with head and neck cancer, ambulatory 24-hour double-probe pH monitoring was performed in 24 untreated patients with laryngeal or pharyngeal squamous cell carcinoma. In addition, 10 patients who had been irradiated in the head and neck area were analyzed for reflux to study the effect of radiotherapy on reflux.

RESULTS

Only 4 of the 24 head and neck cancer patients (17%) had neither pathological laryngopharyngeal nor gastroesophageal reflux. Esophageal acid exposure was abnormal in five patients and acid exposure at the level of the upper esophageal sphincter was abnormal in four patients. Eleven patients had pathological reflux in both areas. Irradiated patients did not differ from the untreated patients considering the incidence of pathological laryngopharyngeal or gastroesophageal reflux.

CONCLUSIONS

The data obtained in this study indicate that reflux is a common event in head and neck cancer patients.

Epiglottitis in adults

Acute epiglottitis has become a disease of adults, probably as a result of immunization of children against Haemophilus influenzae. This article is a review of the literature on epiglottitis, including signs and symptoms, investigation, differential diagnosis, and treatment in the emergency department. The microbiology is discussed and the importance of prophylaxis in exposed persons is stressed.
