Tympanic neurectomy and chorda tympanectomy for the control of drooling

Insights

Surgical intervention for persistent drooling, including tympanic neurectomy, showed limited long-term success in head and neck cancer patients and those with neurological disorders. While some initial improvement was observed, drooling often recurred, indicating disappointing outcomes.

Area of Science:

  • Otolaryngology
  • Neurology
  • Surgical Oncology

Background:

  • Persistent drooling, a challenging condition, significantly impacts quality of life.
  • Causes include sequelae of head and neck cancer resections and neurological disorders like cerebral palsy and cerebrovascular accidents.
  • Current management strategies often fall short, necessitating exploration of surgical interventions.

Observation:

  • Seventeen patients with severe drooling underwent tympanic neurectomy and/or chorda tympanectomy.
  • The cohort included patients with head and neck cancer and those with neurological conditions.
  • Surgical procedures aimed to reduce salivary secretions and alleviate drooling.

Findings:

  • A 41% improvement rate was noted in 12 head and neck cancer patients post-surgery.
  • Two of four children with cerebral palsy experienced initial positive results.
  • Long-term follow-up revealed recurrence of drooling in most patients, indicating limited sustained efficacy.

Implications:

  • Tympanic neurectomy and chorda tympanectomy offer only temporary relief for drooling.
  • Recurrence suggests underlying mechanisms not fully addressed by these surgical approaches.
  • Further research is needed to explore alternative or adjunctive treatments for intractable drooling.
