Fulltext Partial Cricotracheal Resection (PCTR), a Rewarding Outcome for Paediatric Subglottic Stenosis: An Early Experience

Goh BS, Roopesh S, Marina MB, Abdullah SM

Med J Malaysia, 2014 Feb;69(1):13-5.
PMID: 24814622

This is a retrospective study examining the outcome of paediatric patients with subglottic stenosis who underwent partial cricotracheal resection (PCTR) as a primary open procedure from 2004 to 2012. There were 5 patients identified aged from 3 to 18 years old. All the subglottic stenosis were acquired type. All of them were secondary to prolonged intubation. Three patients were classified as Myer-Cotton grade III and the other two were Myer-Cotton grade IV. Two of the patients had concomitant bilateral vocal cord immobility. All patients underwent two staged PCTR . All patients underwent two staged PCTR, and one patient underwent posterior cordectomy apart from partial CTR at different setting. All patients were successfully decannulated at various durations postoperatively. Although this is an early experience in our institution, PCTR has shown to be effective and safe procedure in patients with subglottic stenosis especially those with Myer-Cotton grade III and IV.

Fulltext Unilateral adductor vocal cord palsy treated with the titanium vocal fold medializing implant (TVFMI)

Irfan M, Shahid H, Baharudin A, Friedrich G

Med J Malaysia, 2009 Mar;64(1):89-90.
PMID: 19852333 MyJurnal

Vocal cord palsy secondary to recurrent laryngeal nerve injury may be attributable to trauma, infiltrating neoplasm, congenital cardiac anomaly and others. Regardless the causes, majority of unilateral adductor palsy cases are usually managed by speech rehabilitation in order to allow compensation. In selected cases, medialization procedure may be required to achieve a complete glottal closure during phonation. Multiple techniques have been developed to achieve this goal. This case report illustrates the recent advancement in vocal fold medialization procedure, which has not been widely practiced in Malaysia.

Fulltext Vocal cord hemangioma

Prasad SC, Prasad KC, Bhat J

Med J Malaysia, 2008 Dec;63(5):419-20.
PMID: 19803307

Laryngeal hemangiomas are relatively rare. Laryngeal hemangiomas occur in two main forms--infantile and adult laryngeal hemangiomas. While infantile hemangiomas are usually found to occur in the subglottis, adult hemangiomas occur commonly in the supraglottic regions of the larynx. Laryngeal hemangioma with cavernous features isolated to the free edge of the vocal fold is a very rare clinical finding. We present a case of hemangioma of the right vocal cord in an adult, which was managed successfully in our center.

Fulltext Congenital bilateral vocal cord paralysis

Hasniah AL, Asiah K, Mariana D, Anida AR, Norzila MZ, Sahrir S

Med J Malaysia, 2006 Dec;61(5):626-9.
PMID: 17623966 MyJurnal

Congenital upper airway obstruction is a relatively rare but important cause of major respiratory problems in the neonatal period. Vocal cord paralysis is the second most common cause of congenital airway obstruction presenting with neonatal stridor. It is often the reason for the failure of neonates to wean from the respiratory support. A retrospective analysis of medical record review was conducted. There were seven paediatric patients diagnosed with bilateral vocal fold paralysis in the past three years, of which five were recently diagnosed. All patients underwent flexible with/without rigid bronchoscopes to confirm the diagnosis. This case series highlight our experience in managing the problem of bilateral vocal cord paralysis in the paediatric population, with particular emphasis on their clinical presentations, associated complications and both upper and lower airway abnormalities. The management options and outcome of these patients will also be discussed.

Fulltext Penetrating laryngotracheal trauma resulting in vocal cord avulsion

Lim IR, Aw CY

Med J Malaysia, 2003 Oct;58(4):613-6.
PMID: 15190641

Penetrating neck trauma present difficult management issues by virtue of their rarity. Undiagnosed laryngotracheal injuries have serious implications, especially in the context of multiple trauma, where other injuries overshadow that of the laryngotracheal complex. This is a case of a schizophrenic patient with multiple self-inflicted cuts on his throat and abdomen. Injuries include open, comminuted laryngeal complex lacerations with vocal cord avulsion, as well as evisceration of small bowel. Adequate assessment using both direct laryngoscopy and rigid endoscopy, coupled with open exploration, allowed optimal exposure and fixation of the larynx in the anatomical configuration. The post-operative outcome of the airway and voice remained satisfactory at follow-up. A high index of suspicion coupled with adequate surgical approach allowed establishment of a functional larynx.

Actinomycosis of the vocal cord: a case report

Fernandez SH

Malays J Pathol, 1999 Dec;21(2):111-5.
PMID: 11068416

A 30-year-old Chinese lady was admitted for hoarseness of voice of one month's duration. Clinical examination revealed a granuloma of the left vocal cord while chest X-ray showed an opacity in the lower lobe of the right lung. The provisional clinical diagnosis was tuberculous laryngitis. A biopsy of the vocal cord lesion revealed inflamed tissue with actinomycotic colonies. Cultures and sputum smears did not reveal any tuberculous bacilli. The patient responded to a 6-week course of intravenous C-penicillin, regaining her voice on day 5 of commencement of antibiotics. A subsequent CT scan of the neck and thorax revealed multiple non-cavitating nodular lesions in both lung fields, felt to be indicative of resolving actinomycosis. She was discharged well after completion of treatment. It was felt that this is a case of primary actinomycosis of the vocal cord with probably secondary pulmonary actinomycosis.

Fulltext Hoarseness of Voice in a Patient with Mitral Stenosis and Ortner's Syndrome

Mohamed AL, Zain MM

Malays J Med Sci, 2004 Jul;11(2):65-8.
PMID: 22973129 MyJurnal

Rheumatic mitral stenosis is prevalent in this part of the world and it gives rise to wide array of manifestations. However, hoarseness of voice secondary to recurrent laryngeal nerve paralysis (Ortner's syndrome) is an uncommon manifestation. This case illustrates an uncommon presentation in a common disease. A 29-year-old lady presented with a 2-year history of hoarseness of voice. Physical examination revealed a mid-diastolic murmur and left vocal cord paralysis. Echocardiography confirmed mitral stenosis with pulmonary hypertension. She underwent percutaneous mitral balloon valvotomy in 1991 with return of normal speech after a few months. The recurrent laryngeal nerve paralysis is mainly due to the compression by an enlarged pulmonary artery as initially thought. This complication is rarely seen nowadays due to greater awareness of the disease and earlier intervention. With the advent of percutaneous transvenous mitral valvotomy in the nineties, effective non-surgical intervention is plausible.

Fulltext A Ten-Year Kuala Lumpur Review on Laser Posterior Cordectomy for Bilateral Vocal Fold Immobility

Mawaddah A, Marina MB, Halimuddin S, Mohd Razif MY, Abdullah S

Malays J Med Sci, 2016 Jul;23(4):65-70.
PMID: 27660547 MyJurnal DOI: 10.21315/mjms2016.23.4.9

Bilateral vocal fold immobility (BVFI) is commonly caused by injury to the recurrent laryngeal nerve (RLN) and leads to stridor and dyspnea of varying onsets. A retrospective study was done at the Department of Otorhinolaryngology of Universiti Kebangsaan Malaysia Medical Centre on laser microsurgical posterior cordectomy for BVFI. The objectives were to identify the average duration of onset of stridor from the time of insult and to evaluate the outcome of laser posterior cordectomy as a surgical option. From 1997 to 2007, a total of 31 patients with BVFI were referred for surgery. Twelve patients had tracheostomy done prior to the procedure, whereas 19 patients were without tracheostomy. Ten patients were successfully decannulated, and only 4 patients had complications related to the procedure. The minimum onset of stridor was 7 months, maximum onset of stridor was 28 years, and the mean onset of stridor was 8.7 years. The commonest complication observed was posterior glottic adhesion following bilateral posterior cordectomy. Laser endolaryngeal posterior cordectomy is an excellent surgical option as it enables successful decannulation or avoidance of tracheostomy in patients with BVFI. The onset of stridor took years after the insult to the recurrent laryngeal nerves.

Fulltext Laser posterior cordectomy for bilateral abductor vocal cord palsy : a case report

Mohamad I, Jihan WS, Mohamad H, Abdullah B

Malays J Med Sci, 2008 Jan;15(1):42-3.
PMID: 22589614

Bilateral abductor vocal cord palsy is comparatively a rare vocal cord lesion, especially in a patient with no history of neck mass, previous surgery or trauma. Many patients are not stridulous. A patient presenting with stridor may need emergency airway management before the other treatment is commenced. We report a case of bilateral abductor palsy which required an emergency tracheostomy and subsequently a laser posterior cordectomy.

Vocal fold sulcus

Lee ST, Niimi S

J Laryngol Otol, 1990 Nov;104(11):876-8.
PMID: 2266311

Vocal fold sulcus is a cause of dysphonia which has not been recognized until recently. Awareness of its existence combined with use of laryngostroboscopy would enhance the management of this group of patients. Five such cases were treated initially by voice therapy and subsequently combined with microlaryngeal Teflon injections of the vocal cord. Representative photomicrographs and the end results of treatment are presented. A good voice, subjectively and objectively, was obtained in three patients, with satisfactory improvement in the other two.

Immediate selective laryngeal reinnervation in vagal paraganglioma patients

Mat Baki M, Clarke P, Birchall MA

J Laryngol Otol, 2018 Sep;132(9):846-851.
PMID: 30180919 DOI: 10.1017/S0022215118000476

OBJECTIVE: This prospective case series aimed to present the outcomes of immediate selective laryngeal reinnervation.
METHODS: Two middle-aged women with vagal paraganglioma undergoing an excision operation underwent immediate selective laryngeal reinnervation using the phrenic nerve and ansa cervicalis as the donor nerve. Multidimensional outcome measures were employed pre-operatively, and at 1, 6 and 12 months post-operatively.
RESULTS: The voice handicap index-10 score improved from 23 (patient 1) and 18 (patient 2) at 1 month post-operation, to 5 (patient 1) and 1 (patient 2) at 12 months. The Eating Assessment Tool 10 score improved from 20 (patient 1) and 24 (patient 2) at 1 month post-operation, to 3 (patient 1) and 1 (patient 2) at 12 months. There was slight vocal fold abduction observed in patient one and no obvious abduction in patient two.
CONCLUSION: Selective reinnervation is safe to perform following vagal paraganglioma excision conducted on the same side. Voice and swallowing improvements were demonstrated, but no significant vocal fold abduction was achieved.

A proposal for needle projections in transcutaneous injection laryngoplasty using three-dimensionally reconstructed CT scans

Nasir ZM, Azman M, Baki MM, Mohamed AS, Kew TY, Zaki FM

Surg Radiol Anat, 2021 Aug;43(8):1225-1233.
PMID: 33388863 DOI: 10.1007/s00276-020-02639-9

PURPOSE: This study aims to determine laryngeal dimension in relation to all three transcutaneous injection laryngoplasty (TIL) approaches (thyrohyoid, transthyroid and cricothyroid) using three-dimensionally reconstructed Computed Tomography (CT) scan and compare the measurements between sex, age group and ethnicity.
METHODS: CT scans of the neck of two hundred patients were analysed by two groups of raters. For thyrohyoid approach, mean distance from the superior border of the thyroid cartilage to the laryngeal cavity (THd) and mean angle from the superior border of the thyroid cartilage to mid-true cords (THa) were measured. For transthyroid approach, mean distance from mid-thyroid cartilage to mid-true cords (TTd) and Hounsfield unit (HU) at mid-thyroid cartilage (TTc) were measured. For cricothyroid approach, mean distance from the inferior border of the thyroid cartilage to the laryngeal cavity (CTd) and mean angle from the inferior border of the thyroid cartilage to mid-true cords (CTa) were measured.
RESULTS: There were statistically significant differences between males and females for all measurements except for CTa (p 0.05). There was a significant fair positive correlation between age and TTc (p = 0.0002). For all measurements obtained, there were moderate to excellent inter-group consistency and intra-rater reliability.
CONCLUSION: This study demonstrated a significant sex dimorphism that may influence the three TIL approaches except for needle angulation in the cricothyroid approach. The knowledge of laryngeal dimension is important to increase success in TIL procedure.

Fulltext Should clinical normality be examined in medical course?

Tiong TS

Singapore Med J, 2008 Apr;49(4):328-32.
PMID: 18418526

INTRODUCTION: In medical practice, some patients consult doctors for reassurance of normality, e.g. patients with throat discomfort. Therefore, medical graduates should be competent in diagnosing clinical normality. One way to assess clinical competence is by the objective structured clinical examination (OSCE).
METHODS: In 2002-2006, five batches of medical students who completed their otorhinolaryngology posting in Universiti Malaysia Sarawak were examined with the same OSCE question on clinically normal vocal cords. There were five subquestions concerning structures, clinical features, diagnosis and management. All students had prior slide show sessions regarding normal and abnormal laryngeal conditions.
RESULTS: The total number of students in 2002, 2003, 2004, 2005 and 2006 was 25, 41, 20, 30 and 16, respectively, and 100 percent responded. The average percentage of students with correct answers was 19.4, 2.4, 2.2, 21.2, and 2.4, in the subquestions 0.1 to 0.5, respectively, leaving the remaining relatively larger percentages with incorrect answers of various clinical abnormalities. A reason for these findings is examination fever by the students, who also assumed that all the stations had clinical abnormalities and required differentiating abnormalities from abnormalities, and not from normality. Without clinical normality OSCE questions, the assessment of the undergraduates' clinical competence in real life would seem incomplete.
CONCLUSION: This study showed that a significantly large percentage of students answered incorrectly in the clinical normality OSCE. This may mean that more clinical normality OSCE questions should be included in the undergraduate medical examination to help undergraduates practise the need to look for, and become competent in, clinical normality in real life.

Fulltext In vitro evaluation of genipin-crosslinked gelatin hydrogels for vocal fold injection

Ng WC, Lokanathan Y, Fauzi MB, Baki MM, Zainuddin AA, Phang SJ, et al.

Sci Rep, 2023 Mar 29;13(1):5128.
PMID: 36991038 DOI: 10.1038/s41598-023-32080-y

Glottic insufficiency is one of the voice disorders affecting all demographics. Due to the incomplete closure of the vocal fold, there is a risk of aspiration and ineffective phonation. Current treatments for glottic insufficiency include nerve repair, reinnervation, implantation and injection laryngoplasty. Injection laryngoplasty is favored among these techniques due to its cost-effectiveness and efficiency. However, research into developing an effective injectable for the treatment of glottic insufficiency is currently lacking. Therefore, this study aims to develop an injectable gelatin (G) hydrogel crosslinked with either 1-ethyl-3-(3-dimethylaminpropyl)carbodiimide hydrochloride) (EDC) or genipin (gn). The gelation time, biodegradability and swelling ratio of hydrogels with varying concentrations of gelatin (6-10% G) and genipin (0.1-0.5% gn) were investigated. Some selected formulations were proceeded with rheology, pore size, chemical analysis and in vitro cellular activity of Wharton's Jelly Mesenchymal Stem Cells (WJMSCs), to determine the safety application of the selected hydrogels, for future cell delivery prospect. 6G 0.4gn and 8G 0.4gn were the only hydrogel groups capable of achieving complete gelation within 20 min, exhibiting an elastic modulus between 2 and 10 kPa and a pore size between 100 and 400 μm. Moreover, these hydrogels were biodegradable and biocompatible with WJMSCs, as > 70% viability were observed after 7 days of in vitro culture. Our results suggested 6G 0.4gn and 8G 0.4gn hydrogels as potential cell encapsulation injectates. In light of these findings, future research should focus on characterizing their encapsulation efficiency and exploring the possibility of using these hydrogels as a drug delivery system for vocal fold treatment.

Vocal apparatus structure of the Sarawak frogs (Amphibia: Anura: Ranidae)

Ramlah Zainudin, Elvy Quatrin Deka, Lela Su’ut, Hasnizam Abdul Wahid

Sains Malaysiana, 2015;44:1289-1299.

Studies have shown that some characters, such as morphological, biochemical and behavioural characteristics were shared among con-specifics of closely related frog species. It is hypothesized that closely related frogs would have similar vocal apparatus structure to produce similar call characteristics, in order to be recognized by con-specifics. The vocal apparatus structures of the frogs from Ranidae were, thus, investigated and calls were recorded from various locations in Sarawak, Borneo. The vocal apparatus was sliced and stained using haematoxylin and eosin staining method. The prepared slides were scanned using Dotslide System Olympus BX51. Captured images were further measured using Microscope Olympus BX51. The results showed that the vocal apparatus structure of ranids in Sarawak differed in length between pulvinar vocale and posterior margin (pvpm) or known as vocal cord stricter. This character was deemed to be the most significant character to discriminate the Sarawak ranids. It is suggested that histological analysis is also a good method for study of phenotypic variation of frog species, as shown by the vocal apparatus structure of the anurans. This study provides an alternative method to differentiate taxonomic identity among frog species.

Fulltext Significance of a clean-tip catheter closed suctioning system in a high-setting ventilated, super morbidly obese patient with profuse respiratory secretions

Mazlan MZ, Mohd Zaini RH, Hassan SK, Ali S, Che Omar S, Wan Hassan WMN

Respir Med Case Rep, 2017;21:129-131.
PMID: 28487824 DOI: 10.1016/j.rmcr.2017.04.014

INTRODUCTION: Closed suctioning is commonly used in the context of high-setting mechanical ventilation (MV), given its ability to prevent lung volume loss that otherwise accompanies open suctioning. However, closed suctioning systems (CSS) are not equivalent regarding components and capabilities, and thus this technique may be differentially effective to adequately clear patient secretions from an endotracheal tube (ETT), which is of paramount importance when the tube size makes the ETT particularly vulnerable to block by patient secretions.
CASE PRESENTATION: A 25-year-old super morbidly obese female (body mass index = 55 kg/meter2) presented with worsening shortness of breath. For MV, pairing of a 6 mm (mm) diameter ETT to accommodate the patient's vocal cord edema, with a CSS not designed to maintain a clean catheter tip, precipitated ETT blockage and respiratory acidosis. Replacement of these devices with a 6.5 mm ETT and a CSS designed to keep the catheter tip clean resolved the complications. After use of the different ETT and CSS for approximately one week, the patient was discharged to home.
DISCUSSION: The clean-tip catheter CSS enabled a more patent airway than its counterpart device that did not have this feature. Use of a clean-tip catheter CSS was an important care development for this patient, because this individual's super morbidly obese condition minimized tolerance for MV complications that would exacerbate her pre-existing tenuous respiratory health status.
CONCLUSION: Special attention should be given to the choices of ETT size and CSS to manage super morbidly obese patients who have a history of difficult airway access.
