“…Использовали также методики, при которых к заднему отделу черпаловидного хряща подшивали лопаточно-подъязычную мышцу [46] или грудинощитовидную мышцу соединяли с сухожилием задней перстнечерпаловидной мышцы [54]. Однако дальнейшее наблюдение за пациентами показало, что, помимо высокой травматичности, в послеоперационном периоде часто происходили замещение пересаженной мышцы рубцовой тканью или рубцовая фиксация её с окружающими тканями [48,56].…”

“…При лечении срединных стенозов гортани предлагали также методы нейромышечной пластики, когда реиннервацию производили с помощью нервно-мышечного лоскута. Данный лоскут формировали из нисходящей ветви подъязычного нерва с кусочком одной из мышц: щитоподъязычной (Николаев Н.А., 1926), грудиноподъязычной [30,50], грудинощитовидной [56], лопаточноподъязычной [30,59,60]. Далее нервно-мышечный трансплантат пересаживали в заднюю перстнечерпаловидную [59], боковую перстнечерпаловидную мышцы [50], а лоскут из грудинощитовидной мышцы даже проводили в гортань через окно, сформированное в щитовидном хряще [60].…”

Median stenosis of the larynx, occurring due to paresis or paralysis of the vocal cords, is the most severe pathology in terms of disablement, the treatment complexity and further rehabilitation. Amid the high surgical activity on the organs surrounding larynx, an increase in patients with this pathology is observed. The main surgical approaches in the treatment of bilateral paralytic laryngeal stenosis are described. Two main variants of surgical interventions are emphasized: static - aimed at mechanical expansion of airway lumen, dynamic (functional) - aimed at vocal cord mobility restoration. In considering options aimed at the mechanical expansion of the laryngeal lumen, surgical technique is conventionally used. Most of the authors used removal of the anatomical structures of the larynx to expand its lumen - the vocal cords, arytenoid cartilage, or both at the same time. However, when using these methods, there are possibility of cicatricial changes in violation of the mucosal integrity with recurrent stenosis, eruption of ligatures with the return of the vocal cords in the original position in lateral fixation. In a number of surgical approaches the high invasiveness, technical complexity of execution, as well as the violation of the protective function of the larynx were registered. Among the dynamic methods neuroplasty with an attempt to restore the laryngeal muscles innervation by suturing intersected part of the nerve «end-to-end» and «end-to-side»; myoplasty, when to restore the vocal cords mobility surrounding muscles of the neck were used; neuromuscular plastic, when reinnervation was performed using nerve-muscle flap, were described. The methods are functional, but they have their own disadvantages. The necessity of further search for effective methods of treatment was shown.

The purpose of this investigation was to exclude abductor disturbance and to maintain phonation during recurrent laryngeal nerve paralysis through a new surgical design. This new method consists of implantation of the ansa hypoglossi and sternothyroid muscle pedicle which has been shown to provide sufficient abductor function in a recent publication, and the selective severance ?f t~e abductor branch af~e! neurorrhaphy of the recurrent laryngeal which is shown to be a sufficient adductor function in another study.The recovery of sufficient abductor function during inspiration and dyspnea was 67 % and 89 % of adductor function with phonation. However, after cutting an ~d.ductor nerye branch of the recurrent laryngeal nerve in cases of ins1:1ff1cien~ ab~ucti.on, .the vocal cord on the operated-on side regained abduction durmg msp1rat10n.The effect of the ansa hypoglossi and sternothyroid muscle pedicle is also discussed. 0 INTRODUCTION.

Phonatory function can be reliably tested after vocal paralysis. After a review of 116 cases, 55 patients underwent objective testing. The clinical history of vocal ability and aspiration were found to be significantly correlated with measurements of phonatory mean flow rate (MFR), maximum phonation time (MPT), and maximum decibel output (SPL). A four-stage classification system, based on clinical and objective measurements, has been formulated. In stage I, measures of vocal parameters approached those of normals with MFR = 155 cc/sec, MPT = 12 sec, and SPL = 92 dB. Patients with stage IV disability have high MFR (480 cc/sec), but low MPTs (less than 3 sec) and low SPL values (76 dB). Factors such as sex, age, weight loss, and the presence of malignancy affect the degree of vocal function deficit. Post-therapy recordings indicated an improvement in vocal function by an increase in MPT and SPL, with a decrease in MFR. Measurements of MFR, PT, and SPL are good objective indicators available to the clinician. Functional staging can be applied to assessment and treatment of vocal cord paralysis.
