title: Elective dental extractions and osseointegrated implant replacement to facilitate transoral endoscopic ENT surgical procedures.
abstract: BACKGROUND
  Transoral endoscopic ENT surgical procedures are a mainstay of treatment for a variety of conditions and are often preferable to open surgery where possible. Cases of micrognathia, prominent incisor teeth or trismus may create difficulties in gaining sufficient access to undertake such procedures. Extraction of the anterior maxillary teeth can help overcome these problems in appropriate cases, with subsequent prosthetic tooth replacement supported by dental implants. To date, this approach has not been reported in the literature.
  
  
  METHODS
  This paper reports on two cases which illustrate this approach; the first case involved pharyngeal pouch management where previous open surgery had failed, and the second case involved glottic carcinoma management where oral access was compromising resection.
  
  
  CONCLUSIONS
  This technique is recommended to facilitate effective transoral surgical procedures as a low-morbidity alternative to either open surgery or non-surgical therapies.
