Endoscopic Laryngeal Cleft Instrument Set As Recommended by Reza Rahbar DMD, MD Endoscopic Laryngeal Cleft Instrument Set As Recommended by Reza Rahbar DMD, MD ENT 1 1.0 05/2018/EW-US Endoscopic Laryngeal Cleft Instrument Set As Recommended by Reza Rahbar DMD, MD Endoscopic Laryngeal Cleft Instrument Set As Recommended by Reza Rahbar DMD, MD Laryngeal cleft is a rare congenital anomaly in which the posterior aspect of the larynx fails to fuse, resulting in an aberrant connection between the airway and the esophagus. The incidence of laryngeal cleft is reported to be 1 in 10,000 to 20,000 live births; however, recently it is being diagnosed with increased frequency, with a greater number of patients with type 1 and type 2 clefts being diagnosed. Microlaryngobronchoscopy under general anesthesia, with specific palpation of the interarytenoid region, remains the gold standard in diagnosis. The primary goal of treatment is to resolve feeding difficulties and minimize respiratory complications related to aspiration. Endoscopic repair is possible for type 1, 2, and selective type 3 clefts. Complications of repair include inadequate endoscopic access, making endoscopic repair difficult, and dehiscence of the repair site requiring revision procedure. Because having the appropriate microlaryngeal instrumentation is especially important for facilitating endoscopic repair, our microlaryngeal set contains 13 instruments.

Examination of the entire upper airway is first performed using a PARSONS laryngoscope and a 0º HOPKINS rod lens 4 mm telescope to confirm the diagnosis and identify any coexisting airway pathology. The cleft is identified by palpation of the posterior glottis using the probe. Care must be taken not to apply excessive force and inferior pressure to the posterior glottis with the probe, as this may lead to an incorrect diagnosis. Suspension laryngoscopy is performed with an appropriate size LINDHOLM laryngoscope, ensuring the interarytenoid region is visualized in the center of the microscopic field. Adequate endoscopic exposure of the cleft is vital for success. A universal laryngoscope suspension is used to maintain the exposure. 97052002 ENT 1 1.0 05/2018/EW-US KARL STORZ © 3 The mucosal margin of the cleft is denuded using the CO2 laser under microscopic vision. Where it is not possible to use the standard CO2 laser in the apex of the cleft due to poor visualization, we recommend using the flexible CO2 laser fiber to allow more precise application of the laser beam using either the microscope or 4 mm, 0º HOPKINS telescope for visualization. The LINDHOLM vocal cord retractor is used to splay the cleft open if excessive mucosa is present. The mucosal layers are then apposed with absorbable interrupted sutures, 5-0 Vicryl for an infant or 4-0 Vicryl for an older child (polyglactin; Ethicon, Somerville, NJ), on a reverse cutting needle using the KLEINSASSER needle holder and tied using the knot pusher. The first suture is the most important and must be placed at the most inferior extent of the cleft to prevent persistence of a fistula. Simple interrupted sutures are used passing the needle from posterior to anterior, and then anterior to posterior. Occasionally a figure-of-eight- type suture is used if there is difficulty with exposure; this involves passing the needle from posterior to anterior on both sides of the cleft. Sutures are tied on the posterior surface of the cleft to prevent the formation of granulation tissue in the airway. Generally, two to three sutures are required to close a type 1 or 2 cleft. Once the repair is complete, a 0º HOPKINS telescope is passed into the trachea, and blood or secretions that may have pooled are suctioned. 97052002 ENT 1 1.0 05/2018/EW-US KARL STORZ © 4 Case 1: Pre-Repair Repair End Result 97052002 ENT 1 1.0 05/2018/EW-US KARL STORZ © 5 Ordering Information 8660 P KLEINSASSER Needle Holder, straight, small model, for phonosurgery and endolaryngeal microsurgery, 1.8 x 3.5 mm jaws with cross serration, without ratchet, sheath reinforced from distal to proximal, with cleaning connector, working length 20 cm 8659 C FEHLAND Needle Holder, small model, for phonosurgery and endolaryngeal microsurgery, with ratchet, sheath diameter 3 mm, jaws size 2 x 4 mm, angled 90° to the right, with cleaning connector, working length 20 cm 8659 D FEHLAND Needle Holder, small model, for phonosurgery and endolaryngeal microsurgery, with ratchet, sheath diameter 3 mm, jaws size 2 x 4 mm, angled 90° to the left, with cleaning connector, working length 20 cm 8593 A KLEINSASSER Grasping Forceps, without ratchet, serrated, straight, with cleaning connector, straight, working length 23 cm 8593 AM KLEINSASSER Miniature Grasping Forceps, straight, 97052002 ENT 1 1.0 05/2018/EW-US serrated, sheath conically reinforced from distal to proximal end, with cleaning connector, working length 23 cm KARL STORZ © 6 8683 A Micro Grasping Forceps, straight, serrated, with cleaning connector, working length 20 cm 8684 B Micro Scissors, curved upwards, with cleaning connector, working length 20 cm 8594 A KLEINSASSER Scissors, straight, with cleaning connector, working length 23 cm 8594 B KLEINSASSER Scissors, angled 45°, with cleaning connector, working length 23 cm 8654 B LINDHOLM Forceps, for atraumatic retraction of true vocal cords and false vocal cords, distal end with blunt curved blades, self-retaining, with ratchet and cleaning connector, working length 24 cm 97052002 ENT 1 1.0 05/2018/EW-US 8693 A Probe, straight, diameter 1 mm, working length 20 cm KARL STORZ © 7 Ordering Information 8596 C Hook, blunt, angled 90˚, with probe end, length 5 mm 8596 T KLEINSASSER Knot Tier, working length 23 cm 8657 H Universal Handle, forceps shape, with 2 handle rings, length 9 cm, for use with 3 mm instruments for phonosurgery and endolaryngeal microsurgery 8595 A – 8596 T, 8655 A – K and 8656 A – S 7230 AA HOPKINS® Straight Forward Telescope 0°, enlarged view, diameter 4 mm, length 18 cm, autoclavable, fiber optic light transmission incorporated, color code: green 8575 K Laryngoscope Holder and Chest Support, GÖTTINGEN model, consisting of: 8575 KA Laryngoscope Holder, GÖTTINGEN model, with adjustment wheel 8575 KB Support Rod, movable, with metal ring, diameter 9 cm, length 34 cm 8575 L Support Table, GÖTTINGEN model, for Laryngoscope Holders 8575 K/KC, 8574 KT/KW, autoclavable, consisting of: 8575 LC Swivel Arm, with movable plate 8575 LB Holding Rod, for height adjustment 8575 LA Attachment Blocks, can be mounted on operation 97052002 ENT 1 1.0 05/2018/EW-US table equipped with standard sliding rail 25 x 10 mm KARL STORZ © 8 8587 KK LINDHOLM Operating Laryngoscope, for children, inner proximal end 30 x 20 mm, distal end width 16 mm, length 11 cm 8576 C PARSONS Laryngoscope, size 3, for toddlers, flat distal end for anterior commisure, wide proximal opening enable binocular viewing, right-hand side slotted for introduction of broncho-oesophagoscopes and operating instruments, left-hand side with insufflation channel for oxygen supply, anesthetic gas or jet ventilation, for use with Prismatic Light Deflector 10101 FA/JA/JUA and Laryngoscope Holder 8574 KT/ KW, length 11 cm 8576 B PARSONS Operating Laryngoscope, size 4, for children up to age 12, medium, for anterior commissure, wide proximal opening suitable for binocular viewing, right-hand side slotted for introduction of bronchooesophagoscopes and operating instruments, left-hand side with insufflation channel for oxygen supply, anesthetic gas or for jet ventilation, length 14.5 cm, for use with Clip 497 AC for proximal illumination 97052002 ENT 1 1.0 05/2018/EW-US KARL STORZ © 9 10 Notes 97052002 ENT 1 1.0 05/2018/EW-US KARL STORZ © It is recommended to check the suitability of the product for the intended procedure priortouse. for theintendedprocedure to check thesuitabilityofproduct It isrecommended 97052002 ENT 1 1.0 05/2018/EW-US KARL STORZ © 11 KARL STORZ Endoscopy-America, Inc. 2151 East Grand Avenue El Segundo, CA 90245-5017, USA Phone: +1 424 218-8100 Phone toll free: 800 421-0837 (US only) Fax: +1 424 218-8525 Fax toll free: 800 321-1304 (US only) E-Mail: [email protected] KARL STORZ SE & Co.

    Difficulty Swallowing (Dysphagia) This handout talks about problems your child has in the throat (pharynx) when they swallow, how we diagnose it and how we treat it. What is dysphagia? Dysphagia means difficulty swallowing. Food and drink can get stuck (dis-FAY-je-ya) in the esophagus or “go down the wrong pipe” to the lungs (called aspiration) instead of the stomach. It can also go into the voice box but not all the way into the lungs (called penetration).

  • Injection Augmentation and Endoscopic Repair of Type 1
    Isaac et al. Journal of Otolaryngology - Head and Neck Surgery (2020) 49:49 https://doi.org/10.1186/s40463-020-00447-0 ORIGINAL RESEARCH ARTICLE Open Access Injection augmentation and endoscopic repair of type 1 laryngeal clefts: development of a management algorithm Andre Isaac1* , Orysya Svystun2, Wendy Johannsen1,3 and Hamdy El-Hakim1,3 Abstract Objectives: To describe indications for injection augmentation (IA), endoscopic repair (ER) and conservative methods for the management of type 1 laryngeal cleft (LC1) and propose a management algorithm. We also aimed to compare success of IA and ER and determine independent predictors of treatment failure. Methods: Retrospective study of patients diagnosed with LC1 at a Pediatric Otolaryngology referral centre between 2004 and 2016. All had pre-operative instrumental swallowing evaluation (VFSS/FEES), and were managed with a combination of conservative measures, IA and/or ER. We collected demographics, symptoms, comorbidities, VFSS/ FEES results, and operative details. The primary outcome was symptom resolution by parental report. The secondary outcome was predictors of treatment failure. Results: 88 patients were included in the analysis, with mean age 26 ± 25 months. Most presented with choking events (68%) or recurrent pneumonias (48%). In total, there were 55 IA performed and 45 ER. Of the patients who received IA, 19 required subsequent ER. 95% had symptom improvement, 67% had complete resolution. IA had a 56% long-term success rate, whereas that for ER was 85%. Tube feeding at initial evaluation was an independent predictor of treatment failure (HR 11.33 [1.51–84.97], p = 0.018). Conclusions: LC1 can be effectively managed with a combination of IA and ER with favorable results.

  • Laryngeal Clefts- Associated Syndromes and Management
    [NM-295] Laryngeal clefts- Associated syndromes and Management Tran L, Flotildes K Children's Hospital Los Angeles , Los Angeles , CA, USA Laryngeal clefts are congenital anomalies of the posterior larynx forming a communication between the trachea and esophagus. The incidence of laryngeal clefts is rare, occurring 1 in 10,000 to 20,000 births. We present two patients with laryngeal clefts, one with a mild and the other with a severe form. Patient A was a 4 week old 3.8 kg baby girl born full term with cleft lip, cleft palate, atrial septal defect and ventricular septal defect who presented with coughing during feeds. Imaging showed contrast traveling from the esophagus into the anterior trachea. Direct laryngoscopy and bronchoscopy with spontaneous ventilation revealed an H-type tracheoesophageal fistula and a grade 1 laryngeal cleft. The patient underwent a tracheoesophageal fistula ligation and conservative management was recommended for the laryngeal cleft. Opitz G was considered as a possible diagnosis for the patient’s syndrome. Patient B was a 19 day old 1.1kg born at 29 weeks who presented with respiratory distress. The patient was intubated at birth and had recurrent desaturations and bradycardia when extubated. Direct laryngoscopy and bronchoscopy were performed at bedside instead of the operating room due to desaturation with movement of the endotracheal tube. The patient was found to have a grade 3 laryngeal cleft which required surgical repair with ECMO or cardiopulmonary bypass. Due to the patient's size, prematurity, and guarded prognosis, the family decided to withdraw care. Laryngeal clefts account for 0.2 to 1.5% of congenital airway anomalies and can be associated with syndromes such as Opitz G and Pallister Hall.

Mundada, Department of Anaesthesia and Critical Care, Sir J. J. Group of Hospitals, Mumbai, India. Email: [email protected] Key points Laryngotracheal esophageal cleft (LTEC) is a rare developmental disorder of upper airway which accounts for 0.3% to 0.5% of all congenital anomalies of the larynx. It demands high clinical judgment to diagnose the case as most of the times patient is erroneously diagnosed as tracheoesophageal fistula and recurrent esophageal intubation or slipping of endotacheal tube in the esophagus should arise suspicion of LTEC. It has ben divided into four types by Benjamin and Inglis and severity depends upon type. Type III and IV present with severe symptoms in the neonatal period. Know- ledge of different approaches to secure and maintain airway and preparedness for the same in such a case is most im- portant to prevent catastrophic events. Abstract The trachea and esophagus originate from one common Laryngotracheal esophageal cleft (LTEC) is an abnor- tube and are separated by the rostral development of the mal communication of larynx and trachea with esopha- tracheoesophageal septum, which is complete at appro- gus via a midline defect. This anomaly occurs in less ximately 35 days of gestation. Complete or partial failu- than 1% of population, and has slight male prelidection.

Ashland, PhD, CCC-SLP; Cheryl Hersh, MA, CCC-SLP; Jyoti Ramakrishna, MD; Rie Maurer, MA; Christopher J. Hartnick, MD CME Quiz at jamanetworkcme.com and IMPORTANCE Early diagnosis and assessment in children with type 1 laryngeal cleft are CME Questions page 84 essential in preventing aspiration and associated comorbidity. Appropriate use of conservative and surgical interventions in an evidence-based management strategy can improve overall outcome. OBJECTIVE To evaluate the management of care for children with type 1 laryngeal cleft in our practice and develop an updated management algorithm. DESIGN, SETTING, AND PARTICIPANTS We performed a review of medical records at a tertiary pediatric aerodigestive center. During a period of 7 years (July 18, 2005, to July 18, 2012), 1014 children younger than 18 years were evaluated for aspiration, choking, cough, or recurrent pneumonia. Of these, 44 children (4.3%) had a type 1 laryngeal cleft. Two were lost to follow-up; thus, 42 children were included in our final sample (28 males, 14 females). INTERVENTIONS The care of 15 patients (36%) was managed conservatively, and 27 patients (64%) underwent endoscopic surgical repair of their laryngeal cleft. MAIN OUTCOME AND MEASURE Assessment of our current management strategy. RESULTS Success was defined as improving when a child was able to tolerate a feeding without aspirating or resolved when the child had transitioned to tolerating thin liquids. All patients received a trial of conservative therapy. Fifteen of the 42 patients (36%) had an anatomic cleft and were able to maintain the feeding regimen; thus, conservative treatment was successful in this group.

  • Laryngo-Tracheo-Oesophageal Clefts Nicolas Leboulanger* and Eréa-Noël Garabédian
    Leboulanger and Garabédian Orphanet Journal of Rare Diseases 2011, 6:81 http://www.ojrd.com/content/6/1/81 REVIEW Open Access Laryngo-tracheo-oesophageal clefts Nicolas Leboulanger* and Eréa-Noël Garabédian Abstract A laryngo-tracheo-esophageal cleft (LC) is a congenital malformation characterized by an abnormal, posterior, sagittal communication between the larynx and the pharynx, possibly extending downward between the trachea and the esophagus. The estimated annual incidence of LC is 1/10,000 to 1/20,000 live births, accounting for 0.2% to 1.5% of congenital malformations of the larynx. These incidence rates may however be underestimated due to difficulty in diagnosing minor forms and a high mortality rate in severe forms. A slightly higher incidence has been reported in boys than in girls. No specific geographic distribution has been found. Depending on the severity of the malformation, patients may present with stridor, hoarse cry, swallowing difficulties, aspirations, cough, dyspnea and cyanosis through to early respiratory distress. Five types of laryngo-tracheo-esophageal cleft have been described based on the downward extension of the cleft, which typically correlates with the severity of symptoms: Type 0 laryngo-tracheo- esophageal cleft to Type 4 laryngo-tracheo-esophageal cleft. LC is often associated with other congenital abnormalities/ anomalies (16% to 68%), mainly involving the gastro-intestinal tract, which include laryngomalacia, tracheo-bronchial dyskinesia, tracheo-bronchomalacia (mostly in types 3 and 4), and gastro-esophageal reflux disease (GERD). The syndromes most frequently associated with an LC are Opitz/BBB syndrome, Pallister Hall syndrome, VACTERL/VATER association, and CHARGE syndrome. Laryngeal clefts result from failure of fusion of the posterior cricoid lamina and abnormal development of the tracheo-esophageal septum.
