Perioperative interdisciplinary approach for reduction of opioid use in pediatric tonsillectomy: Protocol using dexmedetomidine and bupivicaine as adjunct agents.

IMPORTANCE: Pediatric tonsillectomy is a common procedure now being performed most often for patients with obstructive sleep apnea, which has been associated with increased sensitivity to the respiratory side effects of opioid medications. This study investigates a strategy to decrease the use of opiate medications in a particularly vulnerable population. OBJECTIVE: Describe an interdisciplinary approach between Otolaryngologists and Anesthesiologists to decrease opiate use in tonsillectomy patients. Demonstrate safety of this protocol. Evaluate the effect of the protocol on intraoperative need for opiate medications and inhaled anesthetic use. Perform cost analysis of the protocol. DESIGN: Retrospective case-control study with cost analysis. SETTING: Tertiary Care Hospital. PARTICIPANTS: Pediatric patients undergoing tonsillectomy at a tertiary care hospital. INTERVENTIONS: Preoperative and intraoperative dexmedetomidine with local bupivacaine injection into the tonsillar fossa. MEASURES: Intraoperative need for sevoflurane, opiate, and propofol. Post-operative pain scores, and utilization of post-operative opiate, acetaminophen, and ibuprofen pain medications. Post-operative adverse events. Cost analysis of protocol. RESULTS: This protocol led to a decrease in intraoperative opiate use by 49.6%, a decrease in intraoperative sevofluorane use by 18%, and a lower reported maximum post-operative pain score without any increase in adverse events. The protocol added a small increase in medication cost of $4.07 to each procedure. CONCLUSION: The use of dexmedetomidine and local anesthetic in pediatric tonsillectomy is a safe and effective protocol that allows for the reduction of opiate use and improved post-operative pain control. KEY POINTS: Question: Can the combination of dexmedetomidine and infiltration of local anesthetic reduce overall opioid use for peediatric patients undergoing tonsillectomy? FINDINGS: In this case-control study, use of dexmedetomidine and local anesthetic injected into the tonsillar fossa led to a decrease in intraoperative opiate use by 49.6%, a decrease in intraoperative sevofluorane use by 18%, and a lower reported maximum pain score without an increase in adverse events. Meaning: Use of dexmedetomidine and local anesthetic as anesthetic adjuncts may help reduce need for intraoperative opiates and decrease the use of volatile anesthetic agents in pediatric tonsillectomy patients, which are undesirable medications in the pediatric population for their respective respiratory depression and potentially neurotoxic side effects.

Intraosseous resection of mandibular arteriovenous malformations: A mandible sparing multi-disciplinary case series.

Mandibular arteriovenous malformations (AVMs) are high flow vascular malformations that can cause pain, hypertrophy, deformity, malocclusion, jaw asymmetry, bone destruction, tooth loss, and severe bleeding [1]. Although general principles apply, the rarity of mandibular AVMs limits definitive agreement on the best course of treatment. Current treatment options include embolization, sclerotherapy, surgical resection, or some combination of techniques [2]. [3]. An alternative multidisciplinary technique of embolization with mandibular-sparing resection is presented. This technique aims to mitigate bleeding with effective removal of the AVM, while preserving mandibular form, function, dentition, and occlusion.

Laser Treatment of Vascular Anomalies.

Lasers are a safe and effective tool for the treatment of vascular anomalies. There are many laser options available. Matching laser parameters with the characteristics of the vasculature in these lesions can selectively deliver energy to the abnormal tissue. This can lead to reduction in size and symptoms of vascular malformations and hemangiomas.

Pediatric Unilateral Vocal Fold Immobility.

Vocal fold immobility in children can affect breathing, swallowing, and speech function. Although sometimes idiopathic, it is often caused by injury to the recurrent laryngeal nerve during cardiac surgery. A detailed history and physical examination can identify risk factors, which affect the rate of resolution and overall prognosis. Fiberoptic laryngoscopy can be used to confirm the diagnosis and evaluate laryngeal anatomy. Many treatment options exist to improve function and quality of life, including vocal fold injection and laryngeal innervation. [Pediatr Ann. 2021;50(7):e286-e291.].

Posterior glottic stenosis: management and outcomes.

PURPOSE OF REVIEW: Pediatric posterior glottic stenosis (PGS) is a challenging clinical entity with multiple treatment options. This review describes the evaluation of patients with PGS and discusses existing surgical techniques. RECENT FINDINGS: PGS secondary to a distinct scar band between the vocal folds can often be effectively managed with endoscopic division and surveillance. More advanced glottic scarring that also involves the interarytenoid mucosa, cricoarytenoid joints, or subglottis merits a more thorough investigation and repair. A postcricoid mucosal advancement flap can be employed in select adolescent or adult PGS, but long-term cricoarytenoid joint mobility is difficult to restore once it has been fixed. Younger pediatric patients have smaller airways and frequent concurrent subglottic stenosis which is better addressed with cartilage grafting. SUMMARY: Surgical success in pediatric PGS depends on careful preoperative airway assessment and the accurate characterization of airway stenosis. A surgical technique should be chosen based on the severity and extent of stenosis.

Transoral approach to type 1 laryngeal cleft repair: A novel, non-endoscopic technique.

Endoscopic type 1 laryngeal cleft repair under spontaneous ventilation can be difficult in patients with poor pulmonary reserve. Intubation makes visualization of the interarytenoid area challenging during an endoscopic repair. As an alternative technique, we utilized a transoral, non-endoscopic approach with a McIvor mouth gag in two such patients. This provided adequate visualization and a larger working field with readily available instrumentation. The ability to intubate the patient obviated the need to intermittently place an endotracheal tube and allowed for uninterrupted working time. This technique does require favorable patient anatomy for adequate exposure, but is worth considering in certain patients.

Hydroxyapatite cement resurfacing the dehiscent jugular bulb: Novel treatment for pulsatile tinnitus.

OBJECTIVES/HYPOTHESIS: The objectives were to discuss the presentation and symptomatology of patients with jugular bulb abnormalities, summarize the literature describing jugular bulb abnormalities, compare methods of treating symptomatic dehiscent jugular bulb, describe a novel surgical technique and pitfalls to repair dehiscent bulbs with hydroxyapatite cement, and present a case series to demonstrate outcomes with this technique STUDY DESIGN: Case series presentation, PubMed literature review, and description of operative technique. METHODS: A series of patients presenting with pulsatile tinnitus due to dehiscent jugular bulbs who underwent operative repair with hydroxyapatite cement resurfacing is described. Literature review was conducted via a PubMed database search. Abstracts and references were reviewed to identify relevant sources. Surgical technique of repair and outcomes are reported. RESULTS: Three patients who presented with unilateral, bothersome, pulsatile tinnitus with history and imaging consistent with a diagnosis of high riding, dehiscent jugular bulbs underwent jugular bulb resurfacing with hydroxyapatite cement. Two patients associated the onset of their symptoms with trauma. All patients reported complete resolution of their tinnitus at an average follow-up of 15 months. No hearing, vestibular, or intracranial complications were encountered. CONCLUSIONS: Compressive, obliterative, and endovascular interventions have been attempted to treat pulsatile tinnitus due to high-riding dehiscent jugular bulbs. Reconstruction of the middle ear floor with autologous tissue grafts has also been described. These techniques have been associated with variable results and with the risk of increased intracranial pressure. Hydroxyapatite cement resurfacing may be considered as an alternative for the treatment of this pathology. LEVEL OF EVIDENCE: 4. Laryngoscope, 128:1186-1190, 2018.

Translabyrinthine vestibular schwannoma resection with simultaneous cochlear implantation.

OBJECTIVES: (1) Report a rare case of translabyrinthine resection of a sporadic vestibular schwannoma (VS) and concurrent cochlear implantation (CI). (2) Discuss pre-, intra-, and post-operative considerations in this unique patient population. (3) Describe surgical and audiologic outcomes reported in this population. METHODS: Case report and review of the literature. PubMed search 'Cochlear Implantation'[Mesh] AND ('Neuroma, Acoustic'[Mesh] OR 'VESTIBULAR SCHWANNOMA'[All Fields] OR 'SCHWANNOMA'[All Fields]) limited to humans and English language. Returned 64 search results, abstracts and references of relevant papers reviewed. RESULTS: A 75-year-old male with longstanding history of slowly progressive severe hearing loss and tinnitus presented for evaluation of worsening imbalance, vertigo, and nausea. Workup revealed a 7 mm right intracanalicular mass on MRI concerning for vestibular schwannoma. Audiogram showed bilateral, symmetric, severe-to-profound sensorineural hearing loss, with poor open-set speech comprehension while bilaterally aided. He underwent successful concurrent right translabyrinthine resection of his VS with complete preservation of the cochlear nerve and uncomplicated cochlear implantation. DISCUSSION: Literature review revealed few previous reports of simultaneous VS and CI. The vast majority of these were in patients with neurofibromatosis Type 2 in whom auditory outcomes were poor. This patient represents one of the few cases of concurrent translabyrinthine tumor removal and CI for a spontaneous VS. CONCLUSION: Single-stage cochlear implantation and translabyrinthine tumor resection is a feasible and safe option to consider for auditory rehabilitation in rare situations.
