Abstract
Pleural effusion is a common problem in our country, and most of these patients need invasive tests as they can't be evaluated by blood tests alone. The simplest of them is diagnostic pleural aspiration, and diagnostic techniques such as medical thoracoscopy are being performed more frequently than ever before. However, most physicians in India treat pleural effusion empirically, leading to delays in diagnosis, misdiagnosis and complications from wrong treatments. This situation must change, and the adoption of evidence-based protocols is urgently needed. Furthermore, the spectrum of pleural disease in India is different from that in the West, and yet Western guidelines and algorithms are used by Indian physicians. Therefore, India-specific consensus guidelines are needed. To fulfil this need, the Indian Chest Society and the National College of Chest Physicians; the premier societies for pulmonary physicians came together to create this National guideline. This document aims to provide evidence based recommendations on basic principles, initial assessment, diagnostic modalities and management of pleural effusions.

NCCP-ICS joint consensus-based clinical practice guidelines on medical thoracoscopy. Lung India 2024; 41:151-167. [PMID: 38700413 PMCID: PMC10959315 DOI: 10.4103/lungindia.lungindia_5_24] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2024] [Revised: 01/10/2024] [Accepted: 01/10/2024] [Indexed: 05/05/2024] Open
Abstract
ABSTRACT Medical Thoracoscopy (MT) is commonly performed by respiratory physicians for diagnostic as well as therapeutic purposes. The aim of the study was to provide evidence-based information regarding all aspects of MT, both as a diagnostic tool and therapeutic aid for pulmonologists across India. The consensus-based guidelines were formulated based on a multistep process using a set of 31 questions. A systematic search of published randomized controlled clinical trials, open labelled studies, case reports and guidelines from electronic databases, like PubMed, EmBase and Cochrane, was performed. The modified grade system was used (1, 2, 3 or usual practice point) to classify the quality of available evidence. Then, a multitude of factors were taken into account, such as volume of evidence, applicability and practicality for implementation to the target population and then strength of recommendation was finalized. MT helps to improve diagnosis and patient management, with reduced risk of post procedure complications. Trainees should perform at least 20 medical thoracoscopy procedures. The diagnostic yield of both rigid and semirigid techniques is comparable. Sterile-graded talc is the ideal agent for chemical pleurodesis. The consensus statement will help pulmonologists to adopt best evidence-based practices during MT for diagnostic and therapeutic purposes.

Indian Guidelines on Nebulization Therapy. Indian J Tuberc 2022; 69 Suppl 1:S1-S191. [PMID: 36372542 DOI: 10.1016/j.ijtb.2022.06.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2022] [Revised: 06/03/2022] [Accepted: 06/09/2022] [Indexed: 06/16/2023]
Abstract
Inhalational therapy, today, happens to be the mainstay of treatment in obstructive airway diseases (OADs), such as asthma, chronic obstructive pulmonary disease (COPD), and is also in the present, used in a variety of other pulmonary and even non-pulmonary disorders. Hand-held inhalation devices may often be difficult to use, particularly for children, elderly, debilitated or distressed patients. Nebulization therapy emerges as a good option in these cases besides being useful in the home care, emergency room and critical care settings. With so many advancements taking place in nebulizer technology; availability of a plethora of drug formulations for its use, and the widening scope of this therapy; medical practitioners, respiratory therapists, and other health care personnel face the challenge of choosing appropriate inhalation devices and drug formulations, besides their rational application and use in different clinical situations. Adequate maintenance of nebulizer equipment including their disinfection and storage are the other relevant issues requiring guidance. Injudicious and improper use of nebulizers and their poor maintenance can sometimes lead to serious health hazards, nosocomial infections, transmission of infection, and other adverse outcomes. Thus, it is imperative to have a proper national guideline on nebulization practices to bridge the knowledge gaps amongst various health care personnel involved in this practice. It will also serve as an educational and scientific resource for healthcare professionals, as well as promote future research by identifying neglected and ignored areas in this field. Such comprehensive guidelines on this subject have not been available in the country and the only available proper international guidelines were released in 1997 which have not been updated for a noticeably long period of over two decades, though many changes and advancements have taken place in this technology in the recent past. Much of nebulization practices in the present may not be evidence-based and even some of these, the way they are currently used, may be ineffective or even harmful. Recognizing the knowledge deficit and paucity of guidelines on the usage of nebulizers in various settings such as inpatient, out-patient, emergency room, critical care, and domiciliary use in India in a wide variety of indications to standardize nebulization practices and to address many other related issues; National College of Chest Physicians (India), commissioned a National task force consisting of eminent experts in the field of Pulmonary Medicine from different backgrounds and different parts of the country to review the available evidence from the medical literature on the scientific principles and clinical practices of nebulization therapy and to formulate evidence-based guidelines on it. The guideline is based on all possible literature that could be explored with the best available evidence and incorporating expert opinions. To support the guideline with high-quality evidence, a systematic search of the electronic databases was performed to identify the relevant studies, position papers, consensus reports, and recommendations published. Rating of the level of the quality of evidence and the strength of recommendation was done using the GRADE system. Six topics were identified, each given to one group of experts comprising of advisors, chairpersons, convenor and members, and such six groups (A-F) were formed and the consensus recommendations of each group was included as a section in the guidelines (Sections I to VI). The topics included were: A. Introduction, basic principles and technical aspects of nebulization, types of equipment, their choice, use, and maintenance B. Nebulization therapy in obstructive airway diseases C. Nebulization therapy in the intensive care unit D. Use of various drugs (other than bronchodilators and inhaled corticosteroids) by nebulized route and miscellaneous uses of nebulization therapy E. Domiciliary/Home/Maintenance nebulization therapy; public & health care workers education, and F. Nebulization therapy in COVID-19 pandemic and in patients of other contagious viral respiratory infections (included later considering the crisis created due to COVID-19 pandemic). Various issues in different sections have been discussed in the form of questions, followed by point-wise evidence statements based on the existing knowledge, and recommendations have been formulated.

Abstract
Flexible bronchoscopy (FB) is commonly performed by respiratory physicians for diagnostic as well as therapeutic purposes. However, bronchoscopy practices vary widely across India and worldwide. The three major respiratory organizations of the country supported a national-level expert group that formulated a comprehensive guideline document for FB based on a detailed appraisal of available evidence. These guidelines are an attempt to provide the bronchoscopist with the most scientifically sound as well as practical approach of bronchoscopy. It involved framing appropriate questions, review and critical appraisal of the relevant literature and reaching a recommendation by the expert groups. The guidelines cover major areas in basic bronchoscopy including (but not limited to), indications for procedure, patient preparation, various sampling procedures, bronchoscopy in the ICU setting, equipment care, and training issues. The target audience is respiratory physicians working in India and well as other parts of the world. It is hoped that this document would serve as a complete reference guide for all pulmonary physicians performing or desiring to learn the technique of flexible bronchoscopy.

Abstract
Bronchial asthma is an important public health problem in India with significant morbidity. Several international guidelines for diagnosis and management of asthma are available, however there is a need for country-specific guidelines due to vast differences in availability and affordability of health-care facilities across the globe. The Indian Chest Society (ICS) and the National College of Chest Physicians (NCCP) of India have collaborated to develop evidence-based guidelines with an aim to assist physicians at all levels of health-care in diagnosis and management of asthma in a scientific manner. Besides a systematic review of the literature, Indian studies were specifically analysed to arrive at simple and practical recommendations. The evidence is presented under these five headings: (1) definitions, epidemiology and impact, (2) diagnosis, (3) pharmacologic management of stable disease, (4) management of acute exacerbations, and (5) non-pharmacologic management and special situations. The modified grade system was used for classifying the quality of evidence as 1, 2, 3, or usual practice point (UPP). The strength of recommendation was graded as A or B depending upon the level of evidence.

Abstract
SETTING Eight operational locations for the Revised National Tuberculosis Control Programme in six Indian states. OBJECTIVE To assess the 6-month efficacy of an intermittent thrice-weekly directly observed treatment (DOT) regimen for tuberculous peripheral adenopathy and the need for prolongation of treatment to 9 months for non-resolution of lymphadenopathy. DESIGN Patients aged >5 years with tuberculous lymphadenopathy were included in the study. Patients were evaluated for resolution at repeat visits following treatment. Those with poor resolution at 6 months were randomised to extended treatment up to 9 months or observation without additional treatment. RESULTS Resolution of lymphadenopathy was observed at the end of 6 months in 517/551 (93.8%) patients. There was a significant difference in response among patients with and those without the presence of systemic symptoms. There was no association between treatment response and number, size, site, consistency and matting of lymphadenopathy. No differences in response were seen in the remaining 34 patients with or without extended treatment. CONCLUSION The operational efficacy of 6-month thrice-weekly DOT for peripheral tubercular lymphadenopathy was satisfactory. There was no evidence of additional benefits of prolonging treatment to 9 months.

Abstract
Isoniazid is a safe and very effective antituberculosis drug. Antimitotic agents routinely cause alopecia. Drug-induced alopecia is usually reversible upon withdrawal of the drug. Isoniazid, thiacetazone and ethionamide are the antituberculosis drugs which have been associated with alopecia. Isoniazid-induced alopecia was observed in one case and confirmed by the finding that hair growth resumed when drug removed from the regimen.

Abstract
Hydropneumothorax complicating to oesophagopleural and broncho-oesophageal fistula is an unusual presentation and is reported in literature as separate clinical entities. Here we present a case of hydropneumothorax with both oesophagopleural and broncho-oesophageal fistula of tuberculous aetiology occurring simultaneously in the same patient. Oesophagopleural fistula was suspected clinically by colour of pleural fluid. Subsequent barium swallow demonstrated leak of contrast material from oesophagus into pleural cavity. Later on, computed tomography of chest with oral contrast confirmed communication of oesophagus with both right pleural cavity and right main bronchus. The fistulous connection between these structures appeared to be due to tuberculous mediastinal lymphadenopathy as evident on CT thorax.

Abstract
INTRODUCTION In recent years, there has been increasing interest in diagnosing various components of chronic obstructive pulmonary disease (COPD) using high-resolution computed tomography (HRCT). The present study was undertaken to evaluate HRCT features in patients with COPD. METHODS 40 male patients with COPD (age 40 years or older) and with a significant smoking history (20 pack-years or more) were included in the study. They were evaluated for HRCT features including vascular attenuation and distortion, mosaic attenuation pattern, directly visible small airways, low attenuation areas of emphysema and measures of hyperinflation of the lungs: tracheal index, sterno-aortic distance, thoracic cage ratio and thoracic cross-sectional area. RESULTS The tracheal index ranged from 0.46 to 0.94; Saber-sheath trachea was found in 14 patients. The mean thoracic cage ratio at two levels, carina and 5 cm below carina, were 0.69 (range 0.61-0.78) and 0.73 (range 0.62-0.83), respectively. Sterno-aortic distance at carinal level ranged from 1.43 to 4.55 cm, with a mean of 3.00 cm. Directly visible small airways was the commonest finding (36 patients), followed by vascular attenuation (25 patients), mosaic attenuation pattern (16 patients) and vascular distortion (8 patients). Among various subtypes of emphysema, centriacinar emphysema was commonest (16 patients), followed by paraseptal (13) and panacinar emphysema (11). CONCLUSION There are certain specific HRCT features of emphysema and it is possible on HRCT to identify the subtypes of emphysema, such as centriacinar, panacinar and paraseptal emphysema. Various features of hyperinflation can also be well identified and quantified on HRCT.

Abstract
We report a case of 60-year old male who had difficulty in breathing as well as in swallowing. On examination, he was found to be having proliferative growth of epiglottis and right aryepiglottic fold mimicking neoplasm. So emergency tracheostomy was performed and biopsy taken. He was found to be having asymptomatic miliary mottling on routine x-ray chest PA view. Further on HRCT, it turned out to be lesion suggesting tubercular etiology. Histopathology (epiglottic biopsy) report confirmed the whole process as tubercular. The patient recovered promptly in due course with anti-tubercular treatment. Point remains to be seen that if we can avoid tracheostomy and its complications in such cases.

Abstract
AIM To evaluate complicated cases of tuberculous cervical lymphadenitis by ultrasonography and computed tomography in order to detect more lymph nodes, and to study their lesions. MATERIAL AND METHODS Total 27 patients of tuberculous cervical lymphadenitis previously proved bacteriologically or histopathologically on anti-tuberculosis treatment (ATT) presenting with complications were taken for study. Each case was subjected to ultrasound (USG) and computed tomography (CT) of involved area. Based on USG and CT findings, patients were subjected to repeat fine needle aspiration cytology (FNAC) of involved lymph node or drainage of pus. RESULTS On USG, all lesions were hypoechoic and showed necrosis. Other findings were: sharp margins in 70.4 %, hilum in 22.2 %, abnormal surrounding tissue in 85.2 %, matting in 37 %, calcification in 29.6 % and posterior enhancement in 22.2 % patients. On CT, majority of lesions were with central low density (CLD) in 16 (59.3 %), followed by large confluent low density (LCLD) in 7 (25.9 %), multilocular central low density (MCLD) in 4 (14.8 %) and homogeneous soft tissue density (HSTD) in 2 (7.4 %) patients. Necrotising granulomatous lymphadenitis was the most common diagnosis in 17 (63%), followed by necrotising in 6 (22.2 %) and granulomatous in 4 (14.8 %) patients. Fifteen (55.5 %) patients were positive for AFB on ZN smear examination. In 17 patients, culture and sensitivity test for Mycobacterium Tuberculosis from lymph node aspirate was done and 12 (70.6 %) patients were found culture positive. Out of these, 2 (16.7 %) were found to be multi-drug resistant (MDR) cases. CONCLUSION USG and CT modalities are complementary in diagnosis and management of tuberculous lymphadenitis presenting with complications. USG helps in better localization of site for biopsy/FNAC procedure and drainage of pus with high diagnostic yield. While CT helps in better anatomical localization of lymph nodes not usually detected on clinical examination.

Abstract
AIMS AND OBJECTIVES The present study was undertaken to evaluate the usefulness of pleural fluid cholinesterase (PChE) level in pleural fluid and its ratio to serum cholinesterase (P/SChE) in order to differentiate transudates and exudates and to compare their diagnostic efficacy with the Light's criteria. MATERIAL AND METHODS A total of 110 patients of pleural effusion of diverse etiology were studied. Eighty patients were of exudative pleural effusion of tubercular, malignant or parapneumonic origin and 30 patients were of transudative effusion. Cholinesterase was estimated in the pleural fluid and serum in all the patients. RESULTS The mean PChE and P/S ChE were significantly higher in exudates as compared to transudates (p < 0.001). P/S ChE was 0.79 +/- 0.45 and 0.14 +/- 0.11 in exudates and transudates, respectively. When a cut-off value of 469 IU/L for PChE was taken for the diagnosis, it was found that 10% of exudates and 2.5% of transudates were misclassified. However percentage of misclassification decreased to 1.25% in exudates and 3.3% in transudates when the cut-off value of 0.24 for P/S ChE ratio was used. Using Light's criteria, a sensitivity of 91.25% and specificity of 90% with positive predictive value (PPV) of 96.05% and negative predictive value (NPV) of 79.42% was observed. However using P/S ChE, the PPV was 98.75% and NPV was 96.67%. CONCLUSIONS The estimation of PChE and P/SChE ratio had better discriminatory capacity than Light's criteria. It is cost effective and more specific, therefore its routine estimation is recommended.

Abstract
Fatal pyothorax following a massive acute retropharyngeal abscess in an adult is reported. Acute non-tuberculous retropharyngeal abscess usually develops following a penetrating injury due to a foreign body or endoscopy. Microbial isolates are mixed and consists of aerobic and anaerobic organisms. It may lead on to mediastinitis since there is a potential communication between the two spaces. Immediate cervical, pleural and mediastinal surgical drainage along with appropriate antibiotics can be life saving.

Abstract
BACKGROUND Spontaneous pneumothorax occurs subsequent to a disruption in the continuity of visceral pleura and escape of air into pleural space. It is usually difficult, sometimes impossible to detect evidence of pulmonary pathology by clinical or conventional radiographic methods. Computed tomography provides additional informations not obtainable with conventional diagnostic modalities. METHODS To determine the role of CT scan in the aetiological diagnosis and subsequent management of patients with primary spontaneous pneumothorax, a perspective study was undertaken. RESULTS A total of 40 patients with spontaneous pneumothorax with normal skiagram chest after management of pneumothorax, were included in the study. In 75% of these cases, CT revealed underlying lung pathology as a cause for primary spontaneous pneumothorax. CONCLUSION Our study shows that CT scan is a useful imaging modality in determining the aetiology of primary spontaneous pneumothorax.

Abstract
Recurrent laryngeal nerve in its course, follows a path that brings it in proximity to numerous structures. These structures can interfere with its function by pressure or by disruption of the nerve caused by disease invading the nerve. We report aortic aneurysm and atherosclerotic plaque as a rare cause of left vocal cord paralysis.

Abstract
Methods for detecting early lung cancers, carcinoma in situ, and dysplastic lesions of the tracheobronchial tree ultimately aim to eradicate them before they become invasive. This approach is being developed to detect early stage lung cancer, when treatment is more likely to be curative. This review describes the recent developments in lung cancer screening and the possible impact on management of lung cancer.

Abstract
Morbidity and mortality due to asthma continue to increase worldwide. One of the reasons is an inadequate patient awareness regarding the disease and its treatment. One thousand four hundred patients with reversible airflow obstruction due to bronchial asthma were included in this study and assigned to one of the four groups depending on whom they had consulted before. The patients were asked to complete a questionnaire which included questions regarding the disease, its course, understanding of treatment schedules, correct use of inhaler devices, use of peak flow meter and when to take emergency actions. The awareness regarding the disease, avoidance of trigger factors, treatment adherence, and correct use of inhaler devices was found to be greater in patients who had received initial treatment from a qualified physician and was best among those treated at the Institute level. The use of peak flow meter by the patients for objective assessment of asthma and the awareness regarding use of emergency care services was found to be poor among all the groups. To improve patient awareness and quality of asthma care delivery, private practitioners as well as Institute doctors must be included in continuing medical education programmes and various methods of communications with patients should be used along with separate clinics for asthma at the Institute level.

Abstract
Ventilation-perfusion (V/Q) imaging has been used as the screening test for pulmonary embolism (PE) for many years with diagnostic algorithms developed as a result of the Prospective Investigation of Pulmonary Embolism Diagnosis study. The primary conclusions were that high probability V/Q scans were reliable indicators for PE and normal or near-normal scans were reliable in the exclusion of PE. With the increasing availability of spiral (helical) computed tomography (CT) and many studies showing a high degree of accuracy for PE, there is much support for the replacement of V/Q by spiral CT. This article reviews the literature concerning V/Q scanning, spiral (helical) CT, and the future potential for magnetic resonance in the diagnosis of PE.

Abstract
Thirty patients of hemoptysis with a normal skiagram chest were evaluated by computed tomography. Majority of the patients were between 21 to 50 years of age. Seventy percent had mild hemoptysis while 30 percent had moderate hemoptysis. Computed tomography provided diagnostic information in 16 patients (53%). The various aetiologies were bronchiectasis (20%), tuberculosis (20%), pneumonia (6.7%), bronchial carcinoid in one case and allergic bronchopulmonary aspergillosis in one case. Computed tomography may play a role in screening patients who present with hemoptysis with normal chest radiographs.

Abstract
State-dependent changes in upper airway caliber were studied with magnetic resonance imaging (MRI) techniques. We hypothesized that changes in airway caliber during sleep in normal subjects would result from positional and dimensional changes in upper airway soft-tissue structures, including the lateral pharyngeal walls, tongue, and soft palate. We used MRI to study 15 normal subjects during wakefulness and sleep. Sleep was facilitated by one night of sleep deprivation prior to MRI. During sleep, the volume of the retropalatal (RP) airway was reduced by 19% (p = 0.03). The volume of the retroglossal (RG) airway was not significantly reduced during sleep, suggesting that the RP region may be more likely to collapse. The mean minimal cross-sectional airway area was reduced by 228% (p = 0.004) in the RP and by 22% (p = 0.02) in the RG region during sleep as compared with values in anatomically matched axial images during wakefulness. Airway anteroposterior (AP) and lateral dimensions were also significantly reduced in the RP region. Airway narrowing in the RP region was associated with a 7% increase in thickness of the lateral pharyngeal walls (p = 0.04). In nine subjects, sagittal data showed significant posterior displacement of the soft palate during sleep as compared with wakefulness. Multiple linear regression analyses indicated that reduction in the RP airway area during sleep resulted from posterior movement of the soft palate, thickening of the lateral pharyngeal walls, and an increase in tongue oblique distance. We conclude that the lateral pharyngeal walls play an important role in upper airway narrowing during sleep in normal subjects.

Abstract
BACKGROUND Left ventricular (LV) effects on right ventricular (RV) function are well known. Less is understood about the effect of the RV on systemic LV mechanics. To determine this interaction, we compared systemic LVs with and without an RV mechanically coupled to them. METHODS AND RESULTS MR myocardial tagging was used to examine 18 subjects with systemic LVs: 10 with functional single LVs (SLV) and 8 normal subjects (NL). Tracking the systolic motion of the intersecting stripes were used to determine regional twist and radial motion. Finite strain analysis was applied to derive principal strains at the atrioventricular valve (AVV) and apical short-axis levels and in 4 anatomic wall regions. Similar E1 (circumferential shortening) strain and heterogeneity of strain were noted between SLV and NL except in the septal wall. At the septal wall, NL displayed greater absolute strain (AVV=-0.16+/-0.02, apex=-0.17+/-0.02) and less heterogeneity of strain than SLV (AVV= -0.12+/-0.02, apex=-0.13+/-0.02). Similar E2 (wall thickening) strain and heterogeneity of strain were also noted between SLV and NL except again at the septal wall. At the septal wall, SLV displayed greater absolute E2 strain (AVV=0.17+/-0.08, apex=0.19+/-0.09) and less heterogeneity of strain than NL (AVV=0.07+/-0.07, apex=0.05+/-0.05). SLV twisted significantly less counterclockwise than NL in 6 of 8 wall regions and actually twisted clockwise at the AVV lateral wall. Although there was no significant difference between groups in radial wall motion, the septal and inferior walls of SLV demonstrated significantly less radial motion compared with other SLV walls. CONCLUSIONS A major influence of the RV on systemic LV strain and radial motion occurs in the septal wall, whereas absence of the RV causes marked differences in LV twist. These findings may yield clues to the long-term functioning of the SLV and be useful in determining strategies for RV augmentation of LV function.

Abstract
In a retrospective study the obstetric behaviour and outcome in 80 teenage pregnancies (< or = 19 years of age) were compared to a control group (n = 80) of women (20-30 years) of same parity. There were 32 booked cases (40%) in study group and 45 (56.2%) in control group (p < 0.05). The overall teenage pregnancy was 3.2%. Majority of patients were 18 years (27.5%) and 19 years (65.0%) in study group and most of them (87.5%) were primiparas. Of all cases 27.5% were grouped under Kuppuswamy classification III in assessing socio-economic status. Anaemia (27.5%), intra-uterine growth retardation (27.5%) and hypertension (15%) were mostly found as complications in study group as compared to controls (11.2%, 8.7% and 8.7% respectively). The incidence of forceps delivery was higher (17.4%) in the study group as compared to controls (6.2%). Stillbirth rate was 1.25% and there was no maternal mortality.

Abstract
Nasal continuous positive airway pressure (CPAP) is the treatment of choice for adults with obstructive sleep apnea. CPAP is known to increase upper airway size; however, the direct effects of CPAP on soft tissue structures surrounding the upper airway are less well understood. Magnetic resonance imaging was used to study the effect of incremental levels (0, 5, 10, and 15 cm H2O) of CPAP on the upper airway and surrounding soft tissue structures in 10 normal subjects. Progressive increases in CPAP resulted in the following major findings: (1) airway volume and airway area (measured at several different locations [midregion, minimal, maximal]) within the retropalatal and retroglossal regions increased; (2) lateral airway dimensional changes were greater than anterior-posterior changes; (3) lateral upper airway soft tissue structural changes were significantly greater than anterior-posterior changes; (4) lateral pharyngeal wall thickness decreased and the distance between the lateral parapharyngeal fat pads increased. An inverse relationship was demonstrated between CPAP level and pharyngeal wall thickness; (5) minimal changes were noted in the soft palate and tongue. These data suggest that the lateral pharyngeal walls are more "compliant" than the soft palate and tongue. This investigation provides further evidence that the lateral pharyngeal walls play an important role in mediating upper airway caliber.
