Adult laryngeal haemangioma is normally seen in the supraglottic or glottic region. Transglottic haemangioma is unusual, and treatment with primary endolaryngeal surgical excision may lead to undesirable bleeding and poor voice outcomes. A 25-year-old female presented with hoarseness and progressive upper airway obstruction symptoms. Videoendoscopy showed haemangioma involving all unilateral subunits of the larynx obstructing half of the subglottis. The transglottic haemangioma was treated with endolaryngeal ethanol injection with prior tracheostomy under local anaesthesia. Endolaryngeal laser surgery was performed later on to remove small residual haemangioma and granuloma. The haemangioma resolved; however, the ethanol injection to the paraglottic space results in vocal fold immobility but with favourable position and good muscle tone and bulk. The patient was successfully decannulated. Post-intervention subjective and objective voice assessments showed normal parameters except slight impairment of voice handicap index-10 with a total score of 12. Adult transglottic haemangioma can cause upper airway obstruction and requires intervention. Excision of the lesion endoscopically without sacrificing voice is achievable.

Acute laryngeal injury is a rare, potentially lethal injury. It often poses difficulty in airway management. Commonly described are external laryngeal or blunt injuries. We report a case of penetrating neck injury resulting in complete transection of cricoid cartilage. A lady presented with a large, deep slash wound in her neck from a knife injury. There was complete laryngotracheal separation. The airway was secured before she was taken to the operating theatre. A tracheostomy was performed. Exploration revealed the cricoid ring was cut horizontally into two. Anastomosis of the cartilaginous framework was undertaken. Fibreoptic laryngoscopy showed bilateral vocal cords paralysis. After two months the patient recovered without airway compromise, she regains her voice. Repeat laryngoscopy showed good mobility of the vocal cords. In conclusion surgical reconstruction should be meticulously done to ensure good respiratory and phonatory abilities.

PMID: 35140081 DOI: 10.1136/bcr-2021-245678

A 79-year-old smoker with a background history of a treated glottic carcinoma and chronic obstructive pulmonary disease presented with progressive hoarseness, symptoms of aspiration and shortness of breath for 6 months. Examination revealed an ulcero-fungating mass over the posterior commissure of the larynx. A tracheostomy, direct laryngoscopy and biopsy of the mass was performed to secure his airway and to exclude recurrent glottic carcinoma. Reassuringly, a histopathological examination of the mass revealed numerous fungal yeast bodies. He was then treated with itraconazole for 4 weeks and was followed up as and outpatient with complete resolution and no recurrence of the disease.

Facilitative playback-based subjective measures offer a more reliable evaluation of the vocal fold vibration than those derived from direct inspection of video playback. One of the measures is a Nyquist plot, which presents the analyzed cycle-to-cycle vibratory information in a graphical form. While the potential is evident, the information of the features of the Nyquist plot, which the evaluation is based on, is still incomplete. The current identified features and their vibratory behaviors may be inadequate to guarantee accurate interpretation of the findings. The present study aims to address this issue by examining the features of the Nyquist plot and their vibratory behaviors. A total of 56 young normophonic speakers, that is, 20 males and 36 females were recruited as the participants. Each of them underwent laryngeal high-speed videoendoscopy to record the images of the vocal fold vibration, which were then analyzed to generate the Nyquist plots. The features were identified by inspecting the properties of the plot points forming the Nyquist plots. For each identified feature, its vibratory behaviors were examined. The results revealed four features: rim contour depicting the longitudinal phase difference; left edge shape signifying the glottal configuration, phase closure, and closed phase duration; rim width and rim pattern visualizing the regularity of glottal areas and the regularity of the intracycle variations, respectively. The findings present a more complete reference of the features and their vibratory behaviors that is pertinent for the Nyquist plot interpretation.

MyJurnal

The ultimate goal of treatment of glottic malignancy is eradication of the cancer and preservation of maximum function. Ideally this would mean return of normal speech, respiration and deglutition. The foundation of vertical partial laryngectomy (VPL) is based on the knowledge of laryngeal anatomy and an understanding of how cancers invade the larynx. The VPL surgery of the glottic cancer is based on oncological sound principles, which will be further disscussed in this article. For the purpose of description we briefly presented 3 of our cases that underwent vertical partial laryngectomy for glottic cancer.

The occurrence of pharyngocutaneous fistula (PCF) after total salvage laryngectomy following radiotherapy
as primary treatment is quite common. In most cases, pharyngocutaneous fistula can heal spontaneously
with conservative measures. Here, we are reporting a 69-year-old male with a residual carcinoma of the
larynx following failed radiotherapy as primary treatment whose later underwent a salvage total
laryngectomy. Post-operatively, it was complicated by the formation of pharyngocutaneous fistula which
was failed to heal with conservative measures and few attempts of surgical repair. The fistula later healed
with the application of Montgomery Salivarybypass tube after 3 weeks. The application of the salivary
bypass tube should be considered and used to promote healing in persistent pharyngocutaneous fistula
especially in a post radiotherapy patient.

Fulltext [A comparison of ramping position and sniffing position during endotracheal intubation: a systematic review and meta-analysis]

Tsan SEH, Ng KT, Lau J, Viknaswaran NL, Wang CY

Braz J Anesthesiol, 2020 11 09;70(6):667-677.

PMID: 33288219 DOI: 10.1016/j.bjan.2020.08.009

OBJECTIVES: Positioning during endotracheal intubation (ETI) is critical to ensure its success. We aimed to determine if the ramping position improved laryngeal exposure and first attempt success at intubation when compared to the sniffing position.

METHODS: PubMed, EMBASE, and Cochrane CENTRAL databases were searched systematically from inception until January 2020. Our primary outcomes included laryngeal exposure as measured by Cormack-Lehane Grade 1 or 2 (CLG 1/2), CLG 3 or 4 (CLG 3/4), and first attempt success at intubation. Secondary outcomes were intubation time, use of airway adjuncts, ancillary maneuvers and complications during ETI.

RESULTS: Seven studies met our inclusion criteria, of which 4 were RCTs and 3 were cohort studies. The meta-analysis was conducted by pooling the effect estimates for all 4 included RCTs (n=632). There were no differences found between ramping and sniffing positions for odds of CLG 1/2, CLG 3/4, first attempt success at intubation, intubation time, use of ancillary airway maneuvers and use of airway adjuncts, with evidence of high heterogeneity across studies. However, the ramping position in surgical patients is associated with increased likelihood of CLG 1/2 (OR=2.05, 95% CI 1.26 to 3.32, p=0.004) and lower likelihood of CLG 3/4 (OR=0.49, 95% CI 0.30 to 0.79, p=0.004), moderate quality of evidence.

CONCLUSION: Our meta-analysis demonstrated that the ramping position may benefit surgical patients undergoing ETI by improving laryngeal exposure. Large-scale well-designed multicentre RCTs should be carried out to further elucidate the benefits of the ramping position in the surgical and intensive care unit patients.

A case of a 21 year old gentleman is described, with no history of preceding trauma, presenting with intermittent dysphagia to solids and fluids for 4 years. Neck examination at rest was normal. However on deep inspiration, the right thyroid lamina protrudes or becomes more prominent. The patient is able to return the larynx to its normal position with manual manipulation. Laryngeal examination with fibreoptic scope during rest and deep breath shows gross rotation of the laryngeal structures for more than 60 degrees on deep breath, with the vocal cords axis rotated to the left side. Management was conservative.

PMID: 16379201

Primary histoplasmosis of the larynx is not a common disease. Most cases of laryngeal histoplasmosis results from hematogenous spread of disseminated histoplasmosis usually originating from pulmonary infection by Histoplasma capsulatum. We report a 52-year-old male chronic smoker who had prolonged hoarseness and was initially diagnosed with laryngeal carcinoma. However, biopsy of the laryngeal mucosa confirmed the diagnosis of histoplasmosis. There were no signs of pulmonary or systemic involvement. Treatment with intravenous amphotericin B was given for a week and oral ketaconazole was given for a month with complete resolution of symptoms.

PMID: 10968058

We report a case of endotracheal tube fire occurring during CO2 laser surgery of the larynx. The ignition of an endotracheal tube was thought to be caused by laser penetration of an unprotected portion of the tube during resection of vocal cord tumour. Fire hazard is inevitable when a laser is used in the path of combustible gases and in the presence of flammable objects. We discuss the methods of prevention that were used.

Fishbones are of particular interest to otolaryngologists. Most fishbones can be removed transorally or via endoscopic guidance. Transcervical neck exploration is occasionally necessary, especially in cases of an embedded foreign body. Computed tomography is the most sensitive and specific imaging modality for identifying embedded fishbones. To our knowledge, this is the first reported case of a laryngeal foreign body embedded in the paraglottic space that was removed using an open approach via a lateral thyroid cartilage window.

Choanal atresia is an uncommon malformation of the upper airway. Bilateral choanal atresia usually detected earlier as it is often associated with severe asphyxia immediately after birth. The diagnosis is often delayed in unilateral type, and mostly presented with unilateral chronic nasal discharge. This condition is rarely encountered but should be considered as a possible differential diagnosis of persistent nasal discharge. We present a case of unilateral congenital choanal atresia in a 4-month-old baby girl presented with persistent unilateral nasal discharge. Diagnostic investigation and possible surgical treatment techniques were discussed.
