Rare Manifestation

Abstract Retropharyngeal tuberculous abscess (RPTBA) is a rare manifestation of tuberculosis (TB) even in high TB burden areas. It rarely manifests as a cause of upper airway obstruction and obstructive sleep apnea (OSA) in children with few case reports in the literature. We report a 22 months old toddler who presented with upper airway obstruction and OSA and was diagnosed with RPTBA. The child recovered completely and growing normally after intra-oral aspiration and 6 months of anti-tuberculosis treatment.

AbstractObstructive sleep apnea is characterized by prolonged partial upper airway obstruction or intermittent complete obstruction that disrupts normal ventilation during sleep and alters normal sleep patterns. Patients with obstructive sleep apnea tend to develop neurocognitive, cardiovascular, behavioral, attention issues, and poor academic performance. Therefore, it is essential to diagnose and treat obstructive sleep apnea early and avoid significant and long-lasting adverse outcomes. Most commonly, upper airway obstruction is caused by enlarged lymphoid tissues within the upper airway, and therefore adenotonsillectomy is considered as the first-line treatment of obstructive sleep apnea in children. Fifty to 70% of patients who have obstructive sleep apnea and treated by surgery are not entirely cured on follow-up polysomnography. In light of this, it is recommended that patients with suspected obstructive sleep apnea undergo a thorough evaluation, and all potential risk factors are identified and treated. The purpose of this review is to familiarize pediatricians with developmental, anatomical, and physiological risk factors involved in the development of obstructive sleep apnea. Additionally, we will present an array of evaluation techniques that can offer adequate assessment of the patient's upper airway anatomy and physiology.

Obstructive Sleep

Objectives. During anesthesia emergence, patients are extubated and the upper airway can become vulnerable to obstruction. Nasal trumpets can help prevent obstruction. However, we have found no manuscript describing how to place nasal trumpets after nasal surgery (septoplasties or septorhinoplasties), likely because (1) the lack of space with nasal splints in place and (2) surgeons may fear that removing the trumpets could displace the splints. The objective of this manuscript is to describe how to place nasal trumpets even with nasal splints in place. Materials and Methods. The authors describe techniques (Double Barrel Technique and Modified Double Barrel Technique) that were developed over three years ago and have been used in patients with obstructive sleep apnea (OSA) and other patients who had collapsible or narrow upper airways (i.e., morbidly obese patients). Results. The technique described in the manuscript provides a method for placing one long and one short nasal trumpet in a manner that helps prevent postoperative upper airway obstruction. The modified version describes a method for placing nasal trumpets even when there are nasal splints in place. Over one-hundred patients have had nasal trumpets placed without postoperative oxygen desaturations. Conclusions. The Double Barrel Technique allows for a safe emergence from anesthesia in patients predisposed to upper airway obstruction (such as in obstructive sleep apnea and morbidly obese patients). To our knowledge, the Modified Double Barrel Technique is the first description for the use of nasal trumpets in patients who had nasal surgery and who have nasal splints in place.

Obstructive Sleep

Obstructive sleep apnea is caused by pharyngeal occlusion due to alterations in upper airway mechanical properties and/or disturbances in neuromuscular control. The objective of the study was to determine the relative contribution of mechanical loads and dynamic neuromuscular responses to pharyngeal collapse during sleep. Sixteen obstructive sleep apnea patients and sixteen normal subjects were matched on age, sex, and body mass index. Pharyngeal collapsibility, defined by the critical pressure, was measured during sleep. The critical pressure was partitioned between its passive mechanical properties (passive critical pressure) and active dynamic responses to upper airway obstruction (active critical pressure). Compared with normal subjects, sleep apnea patients demonstrated elevated mechanical loads as demonstrated by higher passive critical pressures [−0.05 (SD 2.4) vs. −4.5 cmH2O (SD 3.0), P = 0.0003]. Dynamic responses were depressed in sleep apnea patients, as suggested by failure to lower their active critical pressures [−1.6 (SD 3.5) vs. −11.1 cmH2O (SD 5.3), P < 0.0001] in response to upper airway obstruction. Moreover, elevated mechanical loads placed some normal individuals at risk for sleep apnea. In this subset, dynamic responses to upper airway obstruction compensated for mechanical loads and maintained airway patency by lowering the active critical pressure. The present study suggests that increased mechanical loads and blunted neuromuscular responses are both required for the development of obstructive sleep apnea.
