Outcomes of acid suppressive therapy in patients with posterior laryngitis.

OBJECTIVE: To evaluate the results of acid suppressive therapy (AST) in posterior laryngitis (PL) patients with and without documented pharyngeal acid reflux (PAR). METHODS: The charts of all patients with PL who received AST and who had undergone pharyngeal pH monitoring were reviewed. Results of AST in patients with PL with and without documented PAR were evaluated by laryngeal examination, symptom scores, and self-reported overall benefit. RESULTS: Thirty-nine patients with PL had received AST and undergone pharyngeal pH monitoring. Follow-up ranged from 2 to 27 months. Laryngeal findings were improved in patients with and without PAR. Pretreatment total symptom scores were significantly greater than that of posttreatment in patients with and without documented PAR. Overall benefit from AST was reported by the majority of PL patients with and without documented PAR. CONCLUSION: These findings support the use of AST to reduce or eliminate signs and symptoms in PL regardless of documentation of PAR.

Single-stage adult laryngotracheal reconstruction without stenting.

OBJECTIVES/HYPOTHESIS: To present the indications, surgical technique, and results of single-stage laryngotracheal reconstruction (SSLTR) without stenting for laryngotracheal stenosis (LTS) in adults. Various open surgical techniques have been previously described for LTS in adults; however, these techniques usually involve placement of intraluminal stents. The practice of early extubation without stenting is common for pediatric SSLTR. The success of this technique in the pediatric population has led to a trial of the same technique in selected cases of adult LTS. STUDY DESIGN: Retrospective review. METHODS: A retrospective review was conducted on 15 patients with glottic, subglottic, or tracheal stenosis or a combination of these, who underwent SSLTR with composite nasal septal grafts or costal cartilage grafts without stenting. RESULTS: All patients were extubated or decannulated 1 to 7 days after surgery. Three of the 15 patients had no further procedures. Three patients had a second SSLTR to repair stenosis at a different level with no further difficulties. Eight patients had additional endoscopic airway procedures after extubation or decannulation, and one patient died in the immediate postoperative period. All 14 surviving patients are decannulated and well at the time of writing. CONCLUSION: For LTS in selected adult cases, SSLTR without stenting is a viable option. Indications, surgical technique, and complications are presented.

The silent sinus syndrome: a case series and literature review.

PURPOSE: The purpose of this study is to describe the clinical and pathologic features of a form of chronic maxillary atelectasis referred to as the silent sinus syndrome, which is characterized by progressive enophthalmos secondary to maxillary collapse resulting from maxillary sinus hypoventilation. METHODS: A retrospective medical record analysis was carried out to identify patients with enophthalmos secondary to maxillary collapse. Clinical records, including ophthalmology and otolaryngology evaluations as well as computed tomography scans and operative reports, were carefully examined. A complete literature review for relevant studies was performed to examine possible pathophysiology and similar cases. RESULTS: Four patients with enophthalmos and asymptomatic maxillary sinus disease were identified. On computed tomography, all four of the patients had opacified, partially collapsed maxillary sinuses with osteopenia of the sinus walls and orbital floor displacement resulting in enophthalmos. All four underwent successful functional endoscopic sinus surgery and transconjunctival orbital floor repair. CONCLUSION: In some instances, chronic maxillary atelectasis can present with enophthalmos secondary to collapse of the maxillary sinus. For reasons that are unclear, the sinus component of the disease remains asymptomatic and is discovered only after thorough evaluation of the enophthalmos.

An evolution in the management of sinonasal inverting papilloma.

OBJECTIVE: We reviewed the 15-year experience of our institution (Medical College of Wisconsin, Milwaukee, WI) in managing sinonasal inverting papilloma, examining trends in diagnosis and treatment. STUDY DESIGN: Retrospective. METHODS: Thirty-seven patients with inverting papilloma were treated from 1986 to 1999. Demographic data, clinical presentations, pathological findings, surgical approaches and procedures, and recurrence rates were collected retrospectively. Each lesion was categorized into one of four groups based on computed tomography scans and endoscopic findings. This categorization was developed to compare various surgical approaches for tumors in each group. RESULTS: Thirty-one patients had complete information for inclusion in our study. Nineteen patients were treated endoscopically with an average follow-up of 50 months. Eight patients were in group I, five were in group II, six were in group III, and no patients were in group IV. The recurrence rate for the endoscopic group was 10%. Twelve patients underwent lateral rhinotomy or sublabial degloving approach with an average follow-up of 58 months. Five patients were in group I, three patients were in group II, 1 patient was in group III, and three patients were in group IV. The recurrence rate for the external group was 8%. Difference in recurrence rates (P =.85) was not observed between the endoscopic and external approach groups. Regardless of approach, patients who had primary resection had a recurrence of 0%, whereas those with secondary resection had a recurrence of 17% (P =.10). CONCLUSIONS: Technological advancements have led to a trend of detecting sinonasal inverting papilloma before extension beyond the sinonasal region. Difference in recurrence rates was not observed between the endoscopic and the external approach groups. Recurrence rates are lower for primary resection versus secondary resection, regardless of surgical approach.

Loss of secondary esophageal peristalsis is not a contributory pathogenetic factor in posterior laryngitis.

Secondary esophageal peristalsis helps prevent the entry of gastric acid into the pharynx by clearing the refluxed gastric contents back into the stomach. Because the loss of this mechanism may contribute to the pathogenesis of reflux-induced laryngeal disorders, our aim was to study the frequency of stimulation and parameters of secondary esophageal peristalsis in patients with posterior laryngitis (PL). We studied 14 patients (45 +/- 5 years) with PL documented by videolaryngoscopy and 11 healthy controls (46 +/- 6 years). The upper esophageal sphincter (UES) pressure was monitored by a sleeve assembly incorporating an injection port 5 cm distal to the sleeve. The esophageal body and lower esophageal sphincter (LES) pressures were measured by an LES sleeve assembly. Primary esophageal peristalsis was induced by 5-mL water swallows. Secondary esophageal peristalsis was induced by abrupt injection of volumes of air, incrementally increased by 5 mL, into the esophagus. Secondary esophageal peristalsis could not be elicited by injection of any volume (up to 60 mL) in 3 PL patients and 2 controls. These 5 subjects had normal primary peristalsis. The threshold volume of air required to stimulate secondary esophageal peristalsis in PL patients (median, 15 mL) was similar to that of controls (median, 10 mL). The parameters of the secondary esophageal peristaltic pressure wave were similar in both groups, and in both groups, they were similar to those of primary peristalsis. The UES response to the injection of the threshold volume that induced secondary esophageal peristalsis in PL patients was contraction in 58% of the trials, partial relaxation in 3%, and no response in 39%. The findings were similar to those in the controls. The LES response to injection of the threshold volume was complete relaxation in both the PL patients and the controls. We conclude that the integrity of secondary esophageal peristalsis is preserved in PL patients.

Laryngopharyngeal reflux: state of the art diagnosis and treatment.

Gastroesophageal reflux has been implicated in the pathogenesis of a wide variety of otolaryngologic disorders. Patients with otolaryngologic disorders associated with gastroesophageal reflux infrequently have the classic symptoms of gastroesophageal reflux, such as heartburn. Clinical presentation of laryngopharyngeal reflux is commonly characterized by chronic intermittent symptoms. A meticulous synthesis of the information obtained from a complete otolaryngologic examination, diagnostic tests, and response to treatment is essential for the efficient management of patients with otolaryngologic disorders associated with laryngopharyngeal reflux.

Autonomic nervous system evaluation of patients with vasomotor rhinitis.

OBJECTIVE: To demonstrate the utility of quantitative neurological laboratory testing of autonomic nervous system dysfunction and to apply this methodology to further study the relation of chronic vasomotor (nonallergic) rhinitis to the autonomic nervous system. METHODS: It has been suspected that vasomotor rhinitis is due either to a hyperactive parasympathetic nervous system or an imbalance between it and the sympathetic nervous system. The exact relation has not been determined. Recently neurological laboratories have been developed in which a battery of tests can be performed to determine reactivity of the autonomic nervous system. RESULTS: Autonomic nervous system testing was performed on 19 patients with symptoms fulfilling the diagnostic criteria for vasomotor rhinitis and the results were compared with 75 sex- and age-matched control subjects. Patients with vasomotor rhinitis had significant abnormalities of their sudomotor, cardiovagal, and adrenergic subscores. Their composite autonomic scale score was significantly impaired at 2.43, as compared with 0.11 for controls (P < .005). CONCLUSION: Autonomic nervous system dysfunction is significant in patients with vasomotor rhinitis. Possible factors that trigger this dysfunction including nasal trauma and extraesophageal manifestations of gastroesophageal reflux are discussed.

Use of computer-aided surgery for frontal sinus ventilation.

OBJECTIVES: To review our experience and evaluate the utility of computer-aided surgery for frontal sinus and frontal recess disease. STUDY DESIGN: A retrospective review of 31 consecutive patients undergoing computer-aided surgery for frontal sinus ventilation. METHODS: The hospital charts of 31 patients were reviewed. Previous sinonasal procedures, etiology of sinonasal disease, preoperative computed tomography (CT) scan findings, preoperative symptoms, endoscopic and intraoperative findings, type of frontal sinus ventilation procedure, complications, imaging system registration method or accuracy, and postoperative course were noted. RESULTS: In all 31 patients the surgery was successfully completed, and no intracranial or orbital complications were encountered during or after surgery. Six patients required additional surgery including revision transnasal endoscopic frontal sinus ventilation or osteoplastic flaps with fat obliteration. In the six cases requiring additional surgery, disease severity, most commonly, aspirin triad disease, predisposed to failure of frontal sinus ventilation. CONCLUSIONS: Computer-aided surgery is a useful adjunctive device for safe, efficient identification and surgery of the frontal sinus. However, it is not a replacement for sound surgical technique, anatomical knowledge, and experience. In particular, patients with aspirin triad disease with frontal recess and frontal sinus involvement are highly suited for computer-aided surgery and thorough removal of disease, although failures occur despite this technique. The long-term benefit of computer-aided surgery of the frontal sinus has not yet been demonstrated by this or other studies.

Pharyngeal pH monitoring in patients with posterior laryngitis.

OBJECTIVE: To evaluate the diagnostic value of 3-site 24-hour ambulatory pH monitoring in patients with posterior laryngitis (PL) and the prevalence of esophageal abnormalities in this patient group. METHODS: Twenty patients with PL and 17 healthy volunteers were studied as controls. Control subjects had transnasal esophagogastroduodenoscopy (T-EGD) and ambulatory pH monitoring. Patients underwent T-EGD, ambulatory pH monitoring, and barium esophagram. RESULTS: T-EGD documented no abnormality in controls. Esophagitis was present in 2 PL patients, and hiatal hernia in 3. Ambulatory pH monitoring showed that 15 PL patients and 2 controls exhibited pharyngeal acid reflux. Barium esophagram documented gastroesophageal reflux in 5 PL patients. However, none of these barium reflux events reached the pharynx. All PL patients with barium esophagram evidence of gastroesophageal reflux also showed pharyngeal acid reflux by pH monitoring. CONCLUSION: Pharyngeal acid reflux is more prevalent in patients with PL than in healthy controls. Patients with PL infrequently have esophageal sequelae of reflux disease. Ambulatory 24-hour simultaneous 3-site pharyngoesophageal pH monitoring detects gastroesophagopharyngeal acid reflux events in most patients with PL.

Pharyngeal acid reflux in patients with single and multiple otolaryngologic disorders.

OBJECTIVE: This study was designed to determine the prevalence and characteristics of pharyngeal acid reflux (PAR) events in single and multiple otolaryngologic disorders. METHODS: Sixty-seven patients with otolaryngologic symptoms and objective findings and 34 healthy control subjects were studied with an ambulatory 24-hour, 3-site pharyngoesophageal pH monitoring technique. Otolaryngologic diagnosis included isolated posterior laryngitis (PL) in 28 patients, isolated chronic rhinosinusitis (SIN) in 12, combined PL and SIN (PL+SIN) in 6, PL plus laryngotracheal stenosis (PL+LTS) in 12, and PL plus vocal cord nodules (PL+VCN) in 9. RESULTS: PAR events were documented in 68% of patients with PL, 34% of patients with SIN, 67% of patients with PL+SIN, 67% of patients with PL+LTS, 78% of patients with PL+VCN, and 21% of controls. The prevalence of PAR events in patients with isolated PL as well as those with PL combined with other disorders was significantly higher than that in patients without PL and that in controls. As a group, patients with PL had a greater number of PAR events and acid exposure time than other patients and controls. Distal and proximal esophageal reflux parameters were not significantly different among groups. CONCLUSIONS: The prevalence of PAR is significantly higher in patients with isolated PL compared to patients with other isolated otolaryngologic disorders and in controls. The prevalence of PAR in isolated otolaryngologic disorders other than PL is similar to that in healthy controls. The prevalence of PAR is significantly higher in patients with both PL and other otolaryngologic disorders than in controls and in patients with isolated otolaryngologic disorders.

Course of proptosis in patients with Graves' disease after endoscopic orbital decompression.

AIM: To evaluate the results of follow-up and postoperative course of proptosis in patients with Graves' disease who underwent combined transconjunctival and transnasal endoscopic orbital decompression. METHODS: Charts of patients with Graves' disease who underwent orbital decompression using combined transconjunctival and transnasal endoscopic technique were reviewed. The surgical technique involved preservation of the strut of bone between the lamina papyracea of the ethmoid and floor of the orbit of the maxilla. Data pertaining to patient demographics, previous treatments for orbital manifestations of Graves' disease, and preoperative and postoperative otolaryngologic and ophthalmologic examination findings were obtained. Postoperative course of reduction in proptosis was evaluated based on Hertel exophthalmometry measurements obtained in four intervals: 1) 0 to 1 month, 2) 1 month to 3 months, 3) 3 to 6 months, 4) 6 to 12 months. RESULTS: Twenty-eight orbital decompressions were performed on 15 patients. All patients were unresponsive to corticosteroids and orbital irradiation. Ten orbits exhibited preoperative and postoperative visual acuity of 20/20. Vision improved in nine orbits and did not change in six orbits. Proptosis was reduced in 25 orbits. Postoperative course of reduction in proptosis varied within year 1, with the smallest proptosis measurements documented between 6 and 12 months. CONCLUSIONS: Combined transconjunctival and transnasal endoscopic orbital decompression with preservation of the strut resulted in regression of proptosis, marked reduction in postoperative diplopia development, and improvement of visual acuity in patients with Graves' disease. Course of reduction in proptosis varied within postoperative 1 year, with the biggest reduction occurring between 6 and 12 months.

Antileukotriene therapy for the relief of sinus symptoms in aspirin triad disease.

We studied the effect of antileukotriene therapy for the relief of sinus symptoms in patients with aspirin triad disease (ATD). We reviewed the charts of 18 ATD patients who had received antileukotriene therapy. All patients had undergone previous sinus surgery. We then designed a questionnaire to determine the level of each patient's symptoms of chronic rhinosinusitis before and after antileukotriene therapy. Responses were converted to symptom scores. For each patient, the role of therapy in the relief of sinus symptoms was evaluated in three ways: by total symptom scores, by self-reports of overall benefit, and by findings on endoscopic nasal examination. Fifteen of the 18 patients completed the questionnaire. Symptom scores for both major and minor symptoms indicated that nine patients had improved following antileukotriene therapy; three other patients reported some overall benefit from therapy, despite no improvement in their symptom scores. Endoscopic nasal examination findings were consistent with the reports of overall benefit. We conclude that antileukotriene therapy is an effective treatment for most patients whose symptoms of chronic rhinosinusitis persist following sinus surgery.

Pharyngeal acid reflux events in patients with vocal cord nodules.

OBJECTIVE: Gastroesophageal reflux has been implicated in the pathogenesis of vocal cord nodules. However, a cause-and-effect relationship has not been established. Because documentation of pharyngeal acid reflux events makes this correlation more plausible, the aim of the present study was to determine the frequency of pharyngeal acid reflux events in patients with vocal cord nodules. METHODS: Eleven patients with vocal cord nodules (mean age, 42 +/- 6 years) and eleven healthy volunteers (mean age, 45 +/- 6 years) were studied. Patients underwent barium esophagram and ambulatory 24-hour simultaneous three-site pharyngoesophageal pH monitoring. Controls only had ambulatory 24-hour simultaneous three-site pH monitoring. In the ambulatory pH monitoring studies, pH was recorded from the manometrically determined sites of pharynx (2 cm above upper esophageal sphincter), proximal esophagus (10 cm distal to pharyngeal site), and distal esophagus (5 cm above the lower esophageal sphincter). Pharyngeal acid reflux event was deemed acceptable if all three sites recorded a decrease in pH below 4 which was not related to meal or drinking. RESULTS: Pharyngeal acid reflux events occurred in seven of 11 patients with vocal cord nodules (1-4 episodes) and two of 11 controls (1-2 episodes) (P < .05). In both groups all pharyngeal acid reflux events occurred in upright position and were not associated with belching or coughing. Barium studies documented hiatal hernia in two patients and gastroesophageal reflux in five of 11 patients. However, none of the esophageal reflux events reached the pharynx on barium esophagram. CONCLUSIONS: Prevalence of pharyngeal acid reflux events is significantly higher in patients with vocal cord nodules compared with normal controls and suggests a contributory role for gastroesophagopharyngeal acid reflux in the pathogenesis of some vocal cord nodules.

Pharyngo-UES contractile reflex in patients with posterior laryngitis.

BACKGROUND: Earlier studies have shown that stimulation of the human pharynx by injection of minute amounts of water stimulates the pharyngo-UES contractile reflex. It has been suggested that this reflex may be activated during pharyngeal reflux of gastric and/or esophageal content, thus increasing the UES pressure and possibly preventing further entry of the refluxate into the pharynx. However, the integrity of this reflex in patients with posterior laryngitis has not been studied. AIM: Evaluate the pharyngo-UES contractile reflex in a group of patients with objective findings of posterior laryngitis. METHODS: Fourteen consecutive patients with posterior laryngitis (mean age, 48+/-6 y) and 13 healthy volunteers (mean age, 53+/-6 y) were studied by concurrent pharyngeal water stimulation and UES manometry. RESULTS: The threshold volume required to evoke the pharyngo-UES contractile reflex in the laryngitis group (0.4+/-0.05 mL) was significantly higher than that of the control (0.2+/-0.04 mL) (P < .05). Following stimulation of the pharyngo-UES contractile reflex, the maximum postinjection pressure in patients (75+/-6 mm Hg) was similar to that of the controls (78+/-6 mm Hg). The percent increase in UES pressure following stimulation of the reflex in the laryngitis group (99%+/-15%) was significantly higher than that of controls (55%+/-11%) (P < .05). CONCLUSIONS: Compared with normal controls, a significantly larger volume of liquid is required to trigger this reflex in patients with posterior laryngitis. When triggered, the maximum UES pressure induced by the pharyngo-UES contractile reflex is similar between the two groups. These findings suggest an altered afferent sensory limb of this reflex in patients with posterior laryngitis.

Evaluation of gastroesophageal reflux in patients with laryngotracheal stenosis.

To report the incidence of pharyngeal acid reflux events in patients with laryngotracheal stenosis (LTS), we studied 12 patients with LTS and 34 healthy volunteers. All patients and controls underwent ambulatory 24-hour 3-site pH monitoring. In ambulatory pH monitoring, pH was recorded at manometrically determined sites of the pharynx, proximal esophagus, and distal esophagus. For all 3 sites, a pH value below 4 that was not related to the time of oral intake or belching was considered an acid reflux event. Eight of the 12 LTS patients exhibited pharyngeal acid reflux events. In the control group, pharyngeal acid reflux events were documented in 7 subjects. In between-group comparison, the number of reflux episodes and the percent acid exposure time in the pharynx were greater in LTS patients than in controls. Reflux parameters of the proximal and distal esophagus in LTS patients were similar to those of controls. The incidence of pharyngeal acid reflux events in LTS patients was higher than that in controls. It is suggested that identification and treatment of gastroesophageal reflux in patients will significantly simplify and improve the results of treatment for LTS.

The risk and complications of aspiration following cricopharyngeal myotomy.

This article reviews a series of patients undergoing cricopharyngeal myotomy and determines whether clinically dangerous aspiration is seen postoperatively. A total of 23 patients underwent myotomy. Indications included Zenker's diverticulum (14), anticipated or real dysphagia from skull base lesions (5), dysphagia from stroke (2), and dysphagia from glossectomy and radiation therapy (2). Surgical procedures, complications, and effectiveness were reviewed. Of patients with Zenker's diverticula, 13 of 14 had clinically useful improvement in dysphagia. Of patients with skull base lesions, all 5 had improvement (4 of these also had thyroplasites and cervical plexus-to-superior laryngeal nerve anastomoses). Of the patients with strokes, neither had significant improvement. Of the patients with glossectomy and radiation, 1 had useful improvement. Complications were seen in 5 patients: 2 had self-limiting pharyngeal leaks, and 3 had pneumonia 1-4 months postoperatively. One patient also had a postoperative ipsilateral recurrent laryngeal nerve injury. There were no postoperative deaths. In conclusion, cricopharyngeal myotomy has definite utility in the management of cervical dysphagia, even though the etiology of the dysphagia can be multifactorial. Risks directly attributable to the procedure are usually self-limiting; serious complications are usually associated with the underlying disease. The addition of adjunctive procedures, such as thyroplasty and superior laryngeal nerve reinnervation, may be of additional benefit to patients with high extracranial vagal injuries.

Role of refluxed acid in pathogenesis of laryngeal disorders.

The neuroanatomic proximity of the larynx to the hypopharynx and proximal esophagus make it particularly vulnerable to diseases that occur in those 2 areas. This is particularly true of gastroesophageal reflux disease (GERD). There is increasing awareness of this relationship, and dysphonias from gastroesophageal reflux (GER) are far more common than previously realized. The symptoms and findings of reflux laryngitis, vocal nodules, Reinke's edema, contact ulcer and granuloma, laryngeal stenosis, and paroxysmal laryngospasm are presented, and diagnostic protocols for each disorder are suggested. The treatment varies with the severity of each problem. Conservative lifestyles and dietary control are helpful, but long-term medical therapy with H2, H1, and prokinetic drugs are usually needed. Surgical therapy may be indicated for such life-threatening problems as laryngeal stenosis and paroxysmal laryngospasm. The need for physician and patient awareness, research, and improved and less expensive therapy are discussed.
