Simultaneous operations on the thyroid gland and hyoid suspension in patients with combined thyroid pathology and moderate to severe OSA.
The ineffectiveness of conservative treatment of obstructive sleep apnea syndrome (OSAS) (CPAP-therapy) or its rejection leads to a surgical solution of the issue, the purpose of which is to eliminate obvious anatomical obstacles, to increase the lumen of the upper respiratory tract. Modern methods of multilevel surgical treatment of OSAS make it possible to achieve more than 80% success. Most often, at the first stage of OSAS treatment, otorhinolaryngologists use rhinosurgical techniques such as septoplasty, lower submucosal vasotomy, partial conchotomy, removal of nasal polyps, including using endoscopic techniques. At the subsequent stages of multilevel treatment, depending on the level of obstruction and the severity of OSAS, uvulopalatoplasty or uvulopalatopharyngoplasty, partial resection of the tongue or lingual tonsil, suspension of the tongue root and sublingual system, various types of genioplasty and maxillary reduction are performed. This approach allows expanding the airways in the oropharyngeal region and laryngopharynx, improving functional outcomes and quality of life in patients with OSAS. At the same time, first of all, it is necessary to carefully assess the benefits and potential risks of surgical treatment, especially in patients with an unfavorable morbid background and from older age groups. • The investigators will offer patients with concomitant thyroid pathology and moderate or severe OSAS to perform simultaneous operations from one access, where the hyoid bone to the thyroid cartilage will be sutured in the second stage. The stabilization of the hyoid bone and the muscular frame, as an integral complex of the laryngopharynx, increases the airway space and neutralizes obstruction. (1-3) Under endotracheal anesthesia, a horizontal skin incision up to 5 cm long is made at the level of the upper edge of the thyroid cartilage, the skin and subcutaneous fat are dissected. The sternohyoid and sternothyroid muscles are retracted. An audit of the thyroid gland is performed. Step by step, using the ultrasonic dissector, the sections of the gland necessary for resection are separated, ligated, and transected. The vessels of the upper and lower poles are separated with the preservation of blood supply to the right and left upper and lower parathyroid glands. Using a microsurgical technique, neurolysis of the recurrent laryngeal nerves is performed. The control of the integrity of the recurrent laryngeal nerves was performed using the neuromonitoring apparatus. The hyoid bone is mobilized in the anterocaudal direction and is fixed to the thyroid cartilage with four permanent non-absorbable sutures. If sufficient mobilization does not occur during the operation, the tendon of the stylohyoid muscle is dissected. Surgical drainage is installed 24 hours after surgery. Advantages: * access from one incision with combined pathology of the thyroid gland and OSAS which reduces the need for delayed operations; * decrease in apnea hypopnea index (AHI) to 50.7% and subjective daytime sleepiness according to foreign literature.
Under endotracheal anesthesia, a horizontal skin incision up to 50 mm long is made at the level of the upper thyroid cartilage, the skin and subcutaneous fat are dissected. The sternohyoid and sternothyroid muscles are retracted. An audit of the thyroid gland is performed. Step by step, using the ultrasonic dissector, the sections of the gland necessary for resection are separated, ligated and transected. Using microsurgical techniques, neurolysis of the recurrent laryngeal nerves is performed. The quality control of the return of the laryngeal nerves is ensured to the required extent using the neuromonitoring apparatus.

The STOP-BANG questionnaire
The STOP-BANG questionnaire provides 8 possible signs of the presence of apnea: loud snoring; stopping breathing during sleep; daytime tiredness; increased blood pressure; BMI\> 35; neck circumference ≥ 43 cm (41 cm for women), male and over 50 years of age. If there are 3 or more signs, the risk of sleep apnea is considered to be increased.
Time frame: Screening, Day 30 and Day 60
Three-level European quality of life five-dimensional questionnaire
There are five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 3 levels: no problems, some problems, and extreme problems. Patients choice results into a 1-digit number that expresses the level selected for that dimension. The digits for the five dimensions can be combined into a 5-digit number that describe the health status.
Time frame: Screening, Day 30 and Day 60
Apnea-Hypopnea Index (AHI)
Apnea-hypopnea index (AHI) is the total number of episodes of complete or partial cessation of breathing during one hour of sleep (with polysomnography or cardiorespiratory monitoring). AHI is used to assess the severity of OSAS. Calculated using the formula: (number of apnea episodes + number of hypopnea episodes) / sleep or study time. AHI \<5 is considered the norm. Average degree of OSAS 15≤IAG \<30. Severe AHI ≥30. A decrease in the indicator shows an improvement in OSAS during treatment.
Time frame: Screening, Day 30 and Day 60
The Epworth Sleepiness Scale (ESS)
The Epworth Sleepiness Scale (ESS) is a scale for measuring daytime sleepiness using a questionnaire. Helpful in diagnosing sleep disorders. Subjects are asked to rate the likelihood of falling asleep on a scale of increasing probability from 0 to 3 for various situations they encounter in everyday life. The scores for the eight questions are added to form a single number. A number in the range of 0-9 is considered normal, while a number in the range of 10-24 indicates that you should seek professional advice.

Pittsburgh Sleep Quality Index (PSQI) Questionnaire
The Pittsburgh Sleep Quality Index (PSQI) is a questionnaire that assesses sleep quality over a 1 month time frame. It consists of 19 individual elements, making up 7 components that give one overall rating. Each item is weighted on a scale from 0 to 3. The overall PSQI score is then calculated by adding the scores of the seven components to give an overall score of 0 to 21, where lower scores mean healthier sleep quality.
Time frame: Screening, Day 30 and Day 60
Cardiorespiratory monitoring
Cardiorespiratory monitoring - is one of the main methods for diagnosing snoring and breathing disorders during sleep. It allows you to identify episodes of snoring and respiratory arrest (apnea) during sleep, to determine the level of oxygen during episodes of disturbed breathing, to reveal the relationship between apnea and disturbances in the rhythm and conduction of the heart, persistent arterial hypertension, and also to establish the degree of OSA
Time frame: Screening, Day 60
Native endoscopy of the upper respiratory tract with Müller's test
Upper airway endoscopy with Müller's test is performed with flexible optics in a sitting or supine position of the patient. After a forced exhalation, he inhales with his hand closed to his nose and mouth. Levels, shapes and severity of nasal, pharyngeal and laryngeal obstruction are assessed
Time frame: Screening, Day 30 and Day 60
Sleep endoscopy
Sleep endoscopy (drug-induced slip endoscopy (DISE)) is a research method in which the patient is immersed in a drug-induced sleep, at a certain depth of which the sound phenomenon of snoring occurs using a flexible endoscope. All parts of the nose, pharynx and larynx are examined. The degree, shape, and levels of obstruction are determined.
Time frame: Screening, Day 60
The intensity of pain assesment
The intensity of pain is quantified using Verbal Rating Scale. The following scale of verbal assessments is applied: 0 - no pain, 1 point - mild, 2 - moderate, 3 - strong, 4 points - very strong and 5 points - unbearable pain.
Time frame: On the day of surgery, 2 days after the surgery
Pulse oximetry
Pulse oximetry is an indirect method for assessing ventilation. Estimation of the average values of saturation is important for the detection of chronic nocturnal hypoxemia and respiratory failure during sleep. A decrease in average saturation values below 90% indicates severe respiratory failure during sleep.
