Correlations between Morphology, the Functional Properties of Upper Airways, and the Severity of Sleep Apnea

Endoscopic Powered Intracapsular Tonsillectomy and Adenoidectomy in Pediatric Obstructive Sleep Apnea With High-Risk Comorbid Disease Conditions: A Case Series

OBJECTIVE

Pediatric obstructive sleep apnea (OSA) caused by adenoids or an enlarged palatine tonsil has a negative impact on physical and mental growth. Surgical removal of the tissue is effective but entails a life-threatening risk of postoperative bleeding, which is up to 30 times higher in chronic pediatric disease cases. However, endoscopes and resection devices provide safe, reliable surgical methods. Here, we report the efficacy and safety of endoscopic powered intracapsular tonsillectomy and adenoidectomy (PITA) for pediatric OSA in patients with high-risk comorbidities.

METHODS

This retrospective case series included pediatric patients with OSA who underwent PITA at a single tertiary medical center between April 2017 and May 2023. Ten patients (three males and seven females; mean age 6.4 years, range 2-12 years) were included; all met the Japanese criteria for complex chronic pediatric conditions.

RESULTS

The average operative time was 61 min; a microdebrider was used in eight cases and a coblator in two cases. Although there was no postoperative bleeding, one case experienced regrowth.

CONCLUSIONS

Our data show that an endoscopic PITA approach could reduce the risk of severe bleeding and relieve the sleeping conditions of pediatric patients with complex chronic OSA.

Use of Ultrasound to Verify the Impact of Telemedicine Myofunctional Therapy on Sleep Apnea Syndrome: Study Protocol Proposal

The anatomy of the upper airways influences the risk of obstructive sleep apnea (OSA). The size of soft tissue structures, such as the tongue, soft palate, and lateral walls of the pharynx, contributes to the pathogenesis of OSA. New lines of treatment for sleep apnea, such as myofunctional therapy (MT), aim to strengthen the oropharyngeal musculature to improve the defining parameters of apnea. The present protocol uses ultrasound imaging to measure the size of the lingual musculature non-invasively and cost-effectively and evaluates the changes in its morphology. Eligible patients include those with OSA who have undergone submental cervical ultrasound and drug-induced sleep endoscopy before starting MT with the AirwayGym app. Follow-up evaluations are conducted at 3 months after beginning treatment. Patients diagnosed with OSA via questionnaires and polysomnography or respiratory polygraphy are evaluated anatomically and functionally using the Iowa Oral Performance Instrument, a tongue digital spoon, somnoscopy, and submental cervical ultrasound to assess their responses to the AirwayGym app. The lingual thickness (mm) and volume (cm3) and the distance between both lingual arteries (mm) are measured. The AirwayGym app helps users and therapists monitor the patient performance of MT. Incorporating submental ultrasound can be a useful non-invasive tool to evaluate OSA and MT.

Obstructive Sleep Apnea and Its Influence on Intracranial Aneurysm

Obstructive sleep apnea syndrome (OSAS) is associated with cerebrovascular disease, which can lead to life-threatening outcomes. The purpose of the study was to investigate the relationship between OSAS and comorbid intracranial aneurysms. We retrospectively reviewed 564 patients who underwent a polysomnography and brain magnetic resonance angiography as part of their health checkup. We calculated the prevalence of an intracranial aneurysm and OSAS in patients and measured the size of the intracranial aneurysm if present. The mean patient age was 55.6 ± 8.5 years, and 82.3% of them were men. The prevalence of an intracranial aneurysm in patients with OSAS was 12.1%, which is significantly higher than patients with non-OSAS (5.9%, p = 0.031). Patients with OSAS had a much higher prevalence of intracranial aneurysms, after adjusting all possible confounding factors such as age, sex, smoking status, alcohol drinking, and body mass index (odds ratio: 2.32; 95% confidence interval: 1.07-5.04). Additionally, the OSAS group had noticeably larger aneurysms compared with those of the non-OSAS group (3.2 ± 2.0 mm vs. 2.0 ± 0.4 mm, p = 0.013). We found a significant association between OSAS and intracranial aneurysms. OSAS could be another risk factor for the development of intracranial aneurysms.

The Role of Transoral Robotic Surgery in the Era of Hypoglossal Nerve Stimulation

Obstructive sleep apnea (OSA) is a sleep-related breathing disorder characterized by repeated collapses of the upper airway walls, leading to a complete or partial reduction of airflow [...].

Effects of Adenotonsillectomy on Vocal Function

INTRODUCTION

Correct breathing is a fundamental condition for adequate vocal production. Respiratory dynamics are able to modify the growth of facial mass and lingual posture, i.e., of the skull, the mandibular one. For this reason, infant mouth breathing can cause hoarseness.

MATERIALS AND METHODS

We evaluated the actual changes in the characteristics of the voice and articulation of language in a group of subjects affected by adenotonsillar hypertrophy (grade 3-4), with frequent episodes of pharyngo-tonsillitis who underwent adenotonsillectomy. Our study included 20 children-10 boys and 10 girls-aged 4 to 11 years who had adenotonsillar hypertrophy and pharyngotonsillitis episodes exceeding 5-6 per year in the previous 2 years. The control group (Group B) included 20 children-10 boys and 10 girls-aged 4 to 11 years (average age of 6.4 years) who had not undergone surgery and shared the same degree of adenotonsillar hypertrophy as those in Group A but who did not experience recurrent pharyngotonsillitis episodes.

DISCUSSION

The hypertrophy of adenoids and tonsils significantly impacted breathing, vocal function, and speech articulation. All this is responsible for a state of tension in the neck muscles, which at the level of the vocal tract causes hoarseness. The changes objectively observed in our study in the pre- and post-operative phase demonstrate how adenotonsillar hypertrophy is responsible for an increase in resistance to the passage of air at the glottic level.

CONCLUSIONS

For this reason, adenotonsillectomy has an impact on recurrent infections and can also lead to an improvement in speech, breathing, and posture.

Sport in the Laryngectomized Patient: A Literature Review and Single Case Presentation

BACKGROUND

Total laryngectomy is an operation that involves numerous problems for the patient, especially in daily life: loss of the fact, loss of voice, evident scars and persistence of the tracheostoma. Much is known about rehabilitation programs involving the voice, swallowing, shoulder girdle rehabilitation; less explored is the field of sport and sports rehabilitation in the laryngectomized patient.

METHODS

We conduced systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement in order to evaluate the possibilities of practicing sports for the patient after total laryngectomy.

RESULTS

From an initial search of 4191 papers, we have come to include six papers for this literature review. We have also reported one of our clinical cases referring to a laryngectomized patient who swims competitively at an amateur level even after surgery with a particular device. The purpose of this work is to understand the role and importance of sport in rehabilitation and the possibilities that a frail patient like the laryngectomized patient has in practicing sport. Surely the best results are obtained in subjects who practiced sports before surgery.

CONCLUSION

It is evident that sport is important in the psychological and motor recovery of the laryngectomized patient. There is still a lack of clear rehabilitation protocols, especially for water sports, which allow all laryngectomized patients to return to sports. We believe that early resumption of physical activity makes the experience of the disease less dramatic.
