Insights
Topical phenol is safe and well-tolerated for awake tympanostomy tube placement in children. This study found no tympanic membrane complications in over 200 children, supporting its use in pediatric otologic procedures.
Area of Science:
- Otolaryngology
- Pediatric Anesthesia
- Otic Procedures
Background:
- Phenol kits are FDA-approved topical anesthetics for adult tympanic membrane procedures.
- Limited data exists on the safety and efficacy of phenol for tympanic membrane procedures in awake children.
Purpose of the Study:
- To evaluate the safety and complication risks of using topical phenol as a local anesthetic in awake children undergoing office-based otologic procedures.
- To determine if phenol is an effective anesthetic for facilitating procedures like tympanostomy tube placement in pediatric patients.
Main Methods:
- A prospective study involving children under 21 years undergoing tympanostomy tube placement in an awake office setting.
- Phenol was applied to the tympanic membrane prior to tube insertion.
- Outcomes assessed included tympanic membrane perforation, other TM complications, and procedural tolerability, with follow-up of at least 6 months.
Main Results:
- 228 children (6 months to 15.9 years) underwent tympanostomy tube placement with awake topical phenol anesthesia.
- No tympanic membrane complications were reported in 204 children at 3-10 week follow-up.
- None of the 93 children followed for at least 6 months experienced tympanic membrane complications.
Conclusions:
- This study is the first to report on the use of phenol for office-based otologic procedures in children.
- Topical phenol appears to be a safe and tolerable anesthetic option for pediatric patients undergoing procedures like tympanostomy tube placement.
- Phenol represents a potential safe topical anesthetic choice for surgeons performing myringotomies or tympanostomy tube insertions in awake children.
Abstract:
Importance: Phenol kits cleared by the Food and Drug Administration (FDA) are indicated as a topical anesthetic for the tympanic membrane (TM) in adults. However, there is no existing literature that reports outcomes to support the safety and use of phenol on the TM of awake children. Objective: Determine if topical phenol is safe and at low risk for complications and therefore be used effectively in awake children to facilitate office otologic procedures as in adults. Design, Setting, and Participants: Children under 21 years of age whose parents agreed to participate in an awake office setting for tympanostomy tube (TT) placement. All children had TT placement after phenol placement on the TM prior to insertion. Main Outcomes and Measures: TM perforation or other signs of TM complications through a minimum of 6-month clinical follow-up, along with assessment of the tolerability of the procedure by the child. Results: A total of 228 children with an age range of 6 months to 15.9 years and 435 TMs completed TT placement using phenol as a local anesthetic while awake in the office. There were no complications reported in the 204 children at the first follow-up visit post TM placement within 3 to 10 weeks. Of the 93 children followed up at least 6 months, there were no TM complications reported. Conclusions: This is the first study to report the outcomes on the use of phenol in an office setting in children. In this large experience, phenol appears to be tolerable and safe for use in young children in the office and is a potential safe choice of topical anesthesia for surgeons if they choose to perform office procedures such as myringotomies or TT placement on children.
