Lingual Tonsil Hypertrophy Grading and Its Relation to Sociodemographic Factors and Clinical Symptoms

The aim of this research was to evaluate the lingual tonsil hypertrophy (LTH) grading of patients with dysphagia using videolaryngoscopy and determine the relation of LTH grades to sociodemographic factors and clinical symptoms.

Study Overview

• Status: Completed
• Conditions: Dysphagia; Lingual Tonsil Hypertrophy
• Intervention / Treatment: Device: Videolaryngoscopy; Other: Reflux Symptom Index Questionnaire; Other: Dysphagia Screening Questionnaire

Detailed Description

Two groups of people were interviewed during this research - the LTH group and the control group - a total of 100 subjects. The first group was comprised of 50 individuals, who visited the otorhinolaryngologist at Lithuanian University of Health Sciences hospital, regarding dysphagia, and were diagnosed with LTH during endoscopy. The second group consisted of 50 healthy individuals without dysphagia, who did not have enlarged lingual tonsils during assessment using videolaryngoscopy. All subjects filled out the questionnaires, composed of RSI (Reflux Symptom Index) and DSQ (Dysphagia Screening Questionnaire) questionnaires, validated and verified for use in Lithuania, together with a questionnaire created specifically for this research for gathering sociodemographic data.

The LTH grade of all subjects was determined using DelGaudio and Friedman grading systems.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Lingual Tonsil Hypertrophy participants; The research group consisted of 50 consecutive adult outpatients suffering from swallowing disorders, examined by otorhinolaryngologist at the Hospital of Lithuanian University of Health Sciences. Lingual Tonsil Hypertrophy was diagnosed using videolaryngoscopy.	Device: Videolaryngoscopy; A rigid 70 degree laryngoscope is inserted into the subject's oropharynx, which allows to visualize the lingual tonsils. The size of the lingual tonsils is evaluated using DelGaudio and Friedman grading systems.; Other: Reflux Symptom Index Questionnaire; A validated clinical tool for suspecting laryngopharyngeal reflux (LPR). The questionnaire was proposed by Belafsky et al. (2002) and consists of 9 most common gastroesophageal reflux disease (GERD) and LPR symptoms: hoarseness or a problem with your voice; clearing your throat; excess throat mucus or postnasal drip; difficulty swallowing food, liquids, or pills; coughing after you ate or after lying down; breathing difficulties or choking episodes; troublesome or annoying cough; sensation of something sticking in your throat or a lump in your throat; heartburn, chest pain, indigestion, or stomach acid coming up. Each symptom is evaluated on a scale from 0 to 5 (0 - no complaint, 5 - severe symptom). The sum of all symptom evaluations ranges from 0 to 45.; Other: Dysphagia Screening Questionnaire; A validated questionnaire, proposed by Ohkuma et al. (2002). Lithuanian version of the questionnaire consists of 16 questions: choking during swallowing meals / liquids; difficulty eating solid foods; difficult swallowing; feeling of food getting stuck in the throat; longer than before eating time; feeling of food remaining in the mouth; feeling that food or liquid is going up into the throat from the stomach; feeling of food being stuck in the esophagus; weight loss; food getting stuck in the throat; food falling from the mouth; difficulty coughing during or after meals; occurrence of pneumonia; hoarseness; coughing during the night. Interpretation of dysphagia screening questionnaire: Advanced symptom - 2 points; Moderate intensity symptom - 1 point; No symptom - 0 point. At least one advanced symptom means - dysphagia. Higher score represents stronger dysphagia intensity. The maximum score is 32 points.
Other: Control participants; The control group consisted of 50 healthy adult participants, who were examined using videolaryngoscopy and no pharyngeal pathologies were diagnosed, including lingual tonsil hypertrophy.	Device: Videolaryngoscopy; A rigid 70 degree laryngoscope is inserted into the subject's oropharynx, which allows to visualize the lingual tonsils. The size of the lingual tonsils is evaluated using DelGaudio and Friedman grading systems.; Other: Reflux Symptom Index Questionnaire; A validated clinical tool for suspecting laryngopharyngeal reflux (LPR).

Higher score represents stronger dysphagia intensity. The maximum score is 32 points.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Lingual tonsil enlargement grade on videolaryngoscopy	Lingual tonsil enlargement grade was assessed using DelGaudio (2008) and Friedman (2015) grading systems during videolaryngoscopy. According DelGaudio severity of LTH was assessed as: grade 0- lingual tonsils are not enlarged; 1- the lingual tonsils are prominent but not in full contact with the epiglottis or obscuring the valleculae; 2- the lingual tonsils obscure the view of the valleculae and are fully in contact with the epiglottis; 3- the lingual tonsils fill the valleculae and partially or fully obscure the view of the epiglottis. Friedman grading system consists of 0 to 4 scale: 0- complete absence of lymphoid tissue; 1- lymphoid tissue scattered over tongue base; 2- lymphoid tissue covering entirety of tongue base with limited vertical thickness; 3- significantly raised lymphoid tissue covering entirety of the tongue base, approximately 5 to 10 mm in thickness; 4- lymphoid tissue rising above the tip of the epiglottis, 10 or more mm in thickness.	At baseline

Dysphagia Screening Questionnaire	Lithuanian version of the questionnaire consists of 16 questions: choking during swallowing meals / liquids; difficulty eating solid foods; difficult swallowing; feeling of food getting stuck in the throat; longer than before eating time; feeling of food remaining in the mouth; feeling that food or liquid is going up into the throat from the stomach; feeling of food being stuck in the esophagus; weight loss; food getting stuck in the throat; food falling from the mouth; difficulty coughing during or after meals; occurrence of pneumonia; hoarseness; coughing during the night. Interpretation of dysphagia screening questionnaire: Advanced symptom - 2 points; Moderate intensity symptom - 1 point; No symptom - 0 point. At least one advanced symptom means - dysphagia. Higher score represents stronger dysphagia intensity. The maximum score is 32 points.	At baseline
Symptom severity	Participants were asked to evaluate 8 most common LTH symptoms using visual analogue scale (10 cm line, where 0 cm- no symptom, 10 cm- extremely severe symptom). Symptoms: hoarseness; difficult swallowing; painful swallowing; sensation of something sticking in your throat or a lump in your throat; difficult breathing, shortness of breath; snoring; cough; pain in the neck, pharynx.
