Practical Application of Culture-Directed Treatment for Chronic Bacterial Laryngitis.

BACKGROUND/OBJECTIVES: Situated at the center of the upper aerodigestive tract, the larynx often is susceptible to a variety of insults including infection. Manifestations of laryngitis include hoarseness, cough, and sore throat, among others. The purpose of this research is to better understand the clinical presentation and patient characteristics of chronic infectious laryngitis. We aim to better understand when culture-directed therapy should be initiated in patients presenting to the otolaryngologist with suspected chronic infectious laryngitis and how this may influence treatment outcomes. METHODS: A single center, retrospective chart review was performed for patients with laryngitis of >3 weeks duration and who had positive laryngeal cultures obtained at a tertiary referral laryngology office from January 2016 through January 2023. RESULTS: Twenty-four patients (ages 36-84 years) with 29 positive cultures of the larynx met inclusion criteria. Ninety percent of patients were already on acid suppression therapy prior to culture acquisition. Fifty-five percent were immunocompromised. The most common species of bacterial growth included Klebsiella sp. (27.5%), Staphylococcus sp. (27.5%), and methicillin-resistant staphylococcus sp. (13.7%). Twelve cultures (41.4%) revealed multiple bacterial species, and 10 cultures (34.5%) had concomitant fungal isolates. The average treatment duration was 10 days. Twenty-one patients (72%) experienced improvement or resolution in symptoms after completion of culture-directed therapy. CONCLUSIONS: The use of culture-directed therapy for chronic bacterial laryngitis was helpful in the determination of appropriate treatment in these cases. More studies are needed to determine the optimal timing of cultures, duration of treatment, and implications of concomitant fungal laryngitis. LEVEL OF EVIDENCE: 4 Laryngoscope, 134:335-339, 2024.

Ablation of cervical inlet patch for the treatment of globus sensation: A case report.

We present a case of a medically resistant cervical inlet patch causing persistent globus and symptoms of laryngo-pharyngeal reflux, successfully treated with CO2 laser ablation.

Extruded Screw From Cervical Spine Hardware Causing Vocal Fold Paralysis.

Dysphonia and dysphagia are often observed among patients presenting to the otolaryngology clinic. One of the more common etiologies includes iatrogenic injury to the recurrent laryngeal nerve (RLN) as a known complication of head and neck surgeries such as thyroidectomy or anterior approaches to the cervical spine. Most often, RLN injury occurs in this context due to traction or transection of the nerve. No reports on delayed presentation of RLN injury from the extrusion of cervical spine hardware (screw) could be found in the peer-reviewed literature. We present a case of a 63-year-old woman who presented to the otolaryngology office with a 3-month history of hoarseness and difficulty swallowing. The patient's past medical history was significant for a motor vehicle accident (MVA) 6 years prior resulting in right arm radiculopathy and subsequent anterior cervical discectomy with spinal decompression and fusion (ACDF) at C5-C6 and C6-C7 approximately 3 months after the MVA. Strobovideolaryngoscopy revealed right vocal fold immobility. Computed tomography scan revealed that a screw from the right side of the ACDF hardware migrated approximately 2 cm with compression of the RLN. The patient underwent neck exploration with removal of the extruded hardware and microdirect laryngoscopy with right vocal fold injection laryngoplasty. Intraoperatively, the extruded screw was found embedded within the RLN fibers. This case represents the first report to our knowledge of extrusion of cervical spine hardware screw resulting in delayed RLN injury and vocal fold paralysis.

Anaphylactic Food Allergy After Roux-en-Y Gastric Bypass.

The prevalence of obesity in the United States is projected to increase as high as 85% by 2030. Weight loss is associated with improved morbidity and mortality outcomes. Roux-en-Y gastric bypass (RYGB) is an effective procedure recommended for individuals with morbid obesity for weight loss. We report the case of a patient who developed worsening food allergic reactions after RYGB surgery that progressed to an anaphylactic reaction. A 36-year-old female developed an anaphylactic reaction to an ingredient in guacamole eight years after RYGB surgery. Prior to the surgery, she had symptoms consistent with oral allergy syndrome. After the gastric bypass, however, she experienced worsening symptoms. On this occasion, she developed throat tightness prompting a visit to the emergency department where she required emergent intubation for airway protection. Blood testing to assess for an immunoglobin E-mediated allergy to common foods was negative. Despite the negative test, the allergist maintained a high suspicion for the progression of food-pollen syndrome following gastric bypass. Disruption of protein digestion from stomach bypass surgery may result in dietary proteins large enough to elicit immune responses being presented to the immune-rich intestinal mucosa. Additional consideration should be given to patients with a preexisting history of food allergic reactions undergoing RGYB surgery.

Acute infectious laryngitis: A case series.

Although acute laryngitis is common, it is often managed by primary physicians. Therefore, video images documenting its signs are scarce. This series includes 7 professional voice users who previously had undergone baseline strobovideolaryngscopy (SVL) during routine examinations or during evaluations for other complaints and who returned with acute laryngitis. Sequential SVL showed not only the expected erythema, edema, cough, and dysphonia, but also new masses in 5 of the 7 subjects. All the signs returned to baseline. This series is reported to highlight the reversible structural changes that can be expected in patients with acute laryngitis and the value of conservative management.

Histoplasmosis of the head and neck in the immunocompetent patient: Report of 2 cases.

Histoplasmosis of the head and neck is rarely seen in immunocompetent patients. We report 2 new cases of histoplasmosis of the head and neck in immunocompetent patients, one an 80-year-old man and the other a 57-year-old man. The older man presented with oral cavity histoplasmosis; his symptoms included pain, dysphagia, and ulcerative lesions. The younger man had laryngeal histoplasmosis, which resulted in hoarseness and dyspnea. We discuss the methods of diagnosis and the classic findings in histoplasmosis, including the microscopic appearance of caseating granulomas, the results of periodic acid-Schiff staining and Gomori staining, and antibody detection of histoplasmosis. We also review the treatment options with antifungals, including amphotericin B and the oral conazole drugs. With an accurate diagnosis and proper treatment, both of our patients recovered well and their symptoms resolved. Because their symptoms overlapped with those of other, more common disease processes, an accurate diagnosis of these patients was essential to treating their infection.

Hemilaryngeal Microsomia: An Anatomic Variant.

OBJECTIVES: This study aims to describe a congenital laryngeal structural variant, hemilaryngeal microsomia (HLM), and to correlate identification on physical examination with computerized tomography scan (CT) and laryngoscopy findings. METHODS: The study was conducted at a tertiary care center. Six patients presenting with hoarseness were admitted to a tertiary care otolaryngology office. These patients had asymmetrical thyroid cartilage prominence on palpation during physical examination. A diagnosis of HLM was made. All patients underwent laryngostroboscopy and CT scan. Four control patients with normal thyroid cartilage anatomy on physical examination, CT, and stroboscopy results were included for comparison. RESULTS: Disparities in thyroid cartilage angles correlated with documented physical examination findings for six out of six HLM patients. On CT scan, the average difference in left and right thyroid laminar angles was 30.2° ± 18.3° in HLM patients vs 4.00° ± 1.63° in control patients (P = 0.023). Strobosocopic findings also correlated with HLM. The arytenoid cartilage was anteriorly or medially displaced on the microsomic side in all six HLM patients. Three patients had anterior placement of the vocal process resulting in shortening of the vocal fold on the microsomic side of the larynx. CONCLUSIONS: HLM is a congenital structural anomaly of the larynx that may be palpated on physical examination. HLM found on physical examination can be correlated with asymmetries found on CT scan and endoscopy. There is no evidence that the structural features of HLM were causally related to voice symptoms, but the findings on HLM may lead to misdiagnosis. A larger study is indicated to confirm laryngeal structural differences between patients with HLM on physical examination and the general population. Whether or not HLM affects clinical or surgical outcomes remains to be studied.

Laboratory Evaluation of Vocal Fold Paralysis and Paresis.

OBJECTIVES: This study aimed to assess the value of comprehensive laboratory evaluation in patients with vocal fold paralysis or paresis. STUDY DESIGN: This is a retrospective chart review. METHODS: Records of 231 patients with vocal fold paralysis or paresis were reviewed to determine whether there is a significant increase in the number of abnormal test results compared with rates of abnormal results for these tests in the general population and whether testing resulted in clinically important diagnosis. Laboratory data were collected from charts from initial visits from 2010 to 2014 and compared with national data. RESULTS: When controlled for age and sex, white blood cell count was found to have a significantly higher rate of abnormal test results (P < 0.001) in patients with vocal fold paralysis or paresis than the general population. Although hemoglobin, thyroid-stimulating hormone, and thyroid antibody tests were more likely to be abnormal in our patient population, the trend was not statistically significant. Further, the prevalence of syphilis and myasthenia gravis was found to be higher in these subjects than their respective national prevalences, and the incidence of Lyme disease was found to be higher than the national prevalence of Lyme disease. Several patients were diagnosed with medically important conditions such as diabetes, thyroid dysfunction, syphilis, myasthenia gravis, and Lyme disease based on these tests. CONCLUSION: This study suggests that comprehensive testing of patients with vocal fold movement disorders results in diagnoses that would be missed without a comprehensive evaluation, some of which are important medically, although their causal relationship to vocal fold paralysis or paresis was not investigated or established.

A Comparison of Initial and Subsequent Follow-Up Strobovideolaryngoscopic Examinations in Singers.

OBJECTIVES: Previous studies have identified abnormal findings in up to 86.1% of singers on initial screening strobovideolaryngoscopy (SVL) examinations. No studies have compared the prevalence of abnormalities in singers on their subsequent follow-up SVL. Our study evaluates the frequency of these findings in both the initial and subsequent examinations. METHODS: Retrospective charts and SVL reports were reviewed on students from an opera conservatory from 1993 to 2014. All students had initial screening SVL, but only students who later returned with acute voice complaints were included in the study (n = 51, 137 follow-up visits). Normal SVL was defined as an examination without structural or functional abnormalities and reflux finding score ≤7. Data were analyzed using the chi-square test. RESULTS: For initial examinations, 90.2% (including reflux) and 88.2% (excluding reflux) were abnormal. In follow-up examinations, 94.9% (including reflux) and 94.2% (excluding reflux) had abnormal findings, which included muscle tension dysphonia (40.1%), vocal fold (VF) masses (unilateral 48.9%, bilateral 30.7%), vascular abnormalities (unilateral 27.0%, bilateral 5.8%), sulcus (unilateral 17.5%, bilateral 5.1%), VF hypomobility (unilateral 36.3%, bilateral 5.9%), phase (30.6%) and amplitude (44.8%) asymmetries, and glottic insufficiency (49.3%). Follow-up examinations revealed a significant increase in laryngopharyngeal reflux (χ(2) = 7.043; P < 0.05). CONCLUSIONS: We found a higher prevalence of abnormal findings compared with previous studies, which we attributed to a more inclusive definition of abnormal pathologies, improvements in SVL technology, and possibly increased experience with SVL interpretation. This high prevalence of abnormal findings in asymptomatic singers further supports the importance of baseline examinations.

Laryngeal actinomycosis in an immunocompromised patient.

Actinomycosis of the larynx represents an unusual presentation for a common bacterium comprising the oral and oropharyngeal florae. There are few cases reported in the literature of laryngeal actinomycosis occurring primarily in the immunocompromised population. Here, we present a case in a 74-year-old man that occurred in the setting of neutropenia as a result of chemotherapy. Once the diagnosis was made with biopsy of the larynx, the infection was resolved after a prolonged course of penicillin-based therapy.
