Main Component

Phonation is beyond doubt one of the highest functions of the human larynx. The vocal cords, also known as vocal cords, as the name suggests are infolding of mucosa aligned horizontally. The phonatory process, or voicing, occurs when air is expelled from the lungs through the glottis, creating a pressure drop across the larynx. When this drop becomes sufciently large, the vocal cords start to oscillate. The motion of the vocal cords during oscillation is mostly lateral, though there is also some superior component as well. However, there is almost no motion along the length of the vocal cords. The oscillation of the vocal cords serves to modulate the pressure and ow of the air through the larynx, and this modulated airow is the main component of the sound. The sound that the larynx produces is a harmonic series. In other words, it consists of a fundamental tone (called the fundamental frequency, the main acoustic cue for the percept pitch) accompanied by harmonic overtones, which are multiples of the (1) fundamental frequency .

<p class="abstract"><strong>Background:</strong> Vocal cord disorders are very commonly encountered in ENT Outpatient. Electroglottogram is a non-invasive method for the examination of the vocal fold vibrations.  It exerts no influence at all on articulation and production of sound and is cost effective. The aim of the present study was to validate the clinical correlation of electroglottogram in patients presenting with hoarseness of voice<span lang="EN-IN">. </span></p><p class="abstract"><strong>Methods:</strong> 30 patients with history of hoarseness of voice and 30 normals were selected from ENT outpatient and inpatient department over a period of 2 years. All subjects underwent detailed ENT history taking, clinical examination, rigid laryngoscopy and electroglottography and results were documented<span lang="EN-IN">.  </span></p><p class="abstract"><strong>Results:</strong> Electroglottography waveforms of various voice disorders like vocal cord nodule, polyp, papilloma and haemangioma showed specific changes like double peak or notch in closing phase of waveform in case of mass lesion over the vocal cords and fuzzy waveform with prolonged closing time in case of vocal cord palsy. Significant difference was noted in certain electroglottographic parameters for phonated vowels /a/, /i/ and /u/ for certain vocal cord disorders<span lang="EN-IN">. </span></p><p class="abstract"><strong>Conclusions:</strong> Electroglottograph helps in diagnosing the pathology related to vocal cords, whether it is mass lesion over the vocal cords or vocal cord palsy but to differentiate in between mass lesions, clinical examination has to be done to confirm the diagnosis<span lang="EN-IN">.</span></p>

Vocal Cords

Lack of function or malfunction of the vocal cords are not as common manifestations of neuromuscular disorders as dysarthria. It is typically seen in central diseases such as Parkinson disease. Certain muscle and nerve disorders affect the vocal cords, but in these cases, other features of these diseases make the diagnosis easy. Myasthenia gravis (MG) may present with intermittent hoarseness only early in the course of the disease. Consultation with an ear, nose, throat (ENT) specialist is recommended to characterize the type of cord pathology. Hysterical hoarseness and weakness are not unusual presentations to neuromuscular clinics. Unilateral vocal cord palsy is usually due to recurrent laryngeal nerve pathology.

We report a rare case of bilateral vocal cord palsy following total thyroidectomy with successful extubation within 12 hours. The patient is a 33-year-old lady who underwent uneventful total thyroidectomy for compressive symptoms. Thirty minutes after extubation, she developed stridor and the flexible laryngoscopy showed bilaterally adducted vocal cords. The patient, thus, was reintubated and after 12 hours she met the extubation parameters and so she was extubated successfully. The repeated flexible laryngoscopy showed normal vocal cords. A review of the literature revealed limited information on this transient condition.

Ligoniai ir metodai Išnagrinėtos ligos istorijos 5555 pacientų, operuotų Kauno medicinos universiteto klinikų Chirurgijos klinikoje 1998–2004 metais. Skydliaukės operacijos atliktos subfascine ir atvirąja metodika, neidentifikuojant arba identifikuojant grįžtamuosius gerklų nervus. Rezultatai Pooperacinis balso klosčių paralyžius ištiko 127 (2,29%) pacientus: vienos balso klostės klostės – 104 (1,87%), abipusis – 23 (0,41%) pacientus. Po 350 operacijų nuo strumos recidyvo balso klosčių paralyžius pasireiškė 25 (7,14%) pacientams: 16 (4,57%) – vienpusis, 9 (2,57%) – abipusis. Nustatyta, kad chirurginis gydymas pritaikytas įvairioms strumos klinikinėms formoms, skyrėsi tik laikotarpiu, kai į gydymą įsitraukė chirurgai. Išvados Dažniausia skydliaukės operacija yra tiroidektomija (42,11%), dažniausia komplikacija – pooperacinis balso klosčių paralyžius (2,29%). Grįžtamojo gerklų nervo sužalojimus lemia įvairūs veiksniai – strumos patologinė morfologija, ligos recidyvas, ilgalaikis medikamentinis gydymas, nepalankūs skydliaukės ir gretimų struktūrų anatomijos variantai, operacijos apimtis, operacijos metodas. Dėl abipusio balso klosčių paralyžiaus ankstyvuoju pooperaciniu laikotarpiu 4 pacientams kilus kvėpavimo nepakankamumui, tracheostomijos buvo išvengta atlikus vienos balso klostės šoninę fiksaciją. .

We also analyzed the risk factors of postoperative vocal cord paralysis, evaluated and compared the frequency of this complication depending on the indications, extent and methods of surgery. Patients and methods Three thousand eight hundred ninety seven operations on the thyroid were performed at the Clinic of Surgery of Kaunas University of Medicine Hospital during the period 1998–2002. The operations on the thyroid gland have been performed by subfascial and open methods, identifying the recurrent laryngeal nerves. Results Postoperative vocal cord paralysis developed in 97 (2.49%) cases. One-sided vocal cord palsy developed in 81 (2.08%) patients and bilateral in 16 (0.41%) patients. There were 19 (7.49%) cases of vocal cord palsy after 256 operations performed due to recurrent goiter, 13 being one-sided and 6 bilateral. It has been found that surgical treatment is suitable for all clinical forms of goiter, the only difference being the time the surgeons enter the process of treatment. Conclusions The most frequent thyroid gland operation is thyroidectomy (35.69%) and the most frequent complication is postoperative vocal cord paralysis (2.49%). The injuries to the recurrent laryngeal nerve are determined by both objective (thyroid gland pathology, thyroid cancer, recurrence of goiter, long-lasting medical treatment, unfavorable variants of thyroid gland and adjacent anatomic structures and the extent of operation) and subjective factors (methods of operation, surgeon’s experience, operative technique). Individual selection of open or subfascial methods of thyroid operation gives hope to reduce the complications of the surgical treatment. The respiratory insufficiency developing in the early postoperative period due to bilateral vocal cord paralysis can be cured by performing vocal cord laterofixation instead of tracheostomy. Key words: goiter, surgical treatment, recurrent laryngeal nerve palsy, paralysis of vocal cords

ABSTRACT Verrucous lesions of vocal cord are irregular whitish lesion with papillomatous surface. In head and neck region, it commonly affects oral cavity and larynx. Laryngeal lesions cause hoarseness and breathing difficulty. Biopsy of the lesion is essential to look for malignancy. Early lesions are amenable for endoscopic resection. Endoscopic resection can be done with microlaryngeal instruments or using CO2 laser/coblator for precise resection. Here we discuss the role of coblator in endoscopic resection of verrucous lesion of vocal cords. KEYWORDS Coblation, Verrucous lesion of vocal cords, verrucous carcinoma

<p class="abstract"><strong>Background:</strong> Laryngeal disorders are the main culprit for change of voice. Patient presenting with change of voice needs to be assessed for laryngeal disorder. Larynx being part of hypopharynx in the deeper part of cavity has been difficult organ to examine since long, but with technological evolution from artificial light to flexible scopes to stroboscope has made life easier for a laryngologist to evaluate laryngeal disorder thoroughly.</p><p class="abstract"><strong>Methods:</strong> In this study we have included all cases of change of voice coming to department of ENT and head and neck surgery at GMERS Medical College and Hospital, Gotri in last one year with change of voice for more than one month including vocal cord malignancy. A detailed history and thorough examination of ENT and in particular larynx done. Further work up and management was done according to case base need.  </p><p class="abstract"><strong>Results:</strong> Out of 50 patients enrolled in the study we found 48% males and 42% females. Most of the patients were adults. Only 4% were in geriatric age group. Most common diagnosis was vocal cord nodules 26% followed by hypertrophy of vocal cords16%. Malignancy of the vocal cords was found to be 14% followed by10% of vocal cord polyp and vocal cord palsy 10%. Other conditions were found to be 6%.</p><p class="abstract"><strong>Conclusions:</strong> Stroboscopy is a great tool for evaluation of vocal cord pathology in particular subtle diseases of vocal cords. Along with diagnosis we can have proper documentation of dynamic movement of vocal folds with help of stroboscopy.</p>

Abductor Paralysis

AbstractDifferent techniques were compared in management of 36 patients with bilateral abductor paralysis of the vocal cords. Ten patients were treated by microsurgical arytenoidectomy through a mid-line thyrotomy, with successful decannulation in only three. Fifteen patients were treated by endolaryngeal microsurgical arytenoidectomy, with failure to decannulate four cases.The procedure of endoscopic laterofixation of the vocal cord was used to treat 11 patients. Ten patients had an adequate long-lasting airway with a socially acceptable voice function. One patient had a revision surgery and was successfully decannulated. The technique was found to be a reliable option in the management of bilateral abductor paralysis. It is a modifiable procedure with a feasibility to adjust the position of the vocal cord under endoscopic control. It can be combined with endolaryngeal arytenoidectomy if the gain in the airway size produced by laterofixation is found insufficient.
