Lingual Split Technique
A historical method for removing impacted mandibular third molars by splitting and temporarily removing the lingual cortical plate to gain access to the tooth.
Full Definition
The lingual split technique, associated primarily with Sir William Kelsey Fry, involves intentionally fracturing the lingual cortical plate with a chisel to facilitate removal of deeply impacted lower wisdom teeth. Because the lingual nerve lies in close proximity to this bone, the technique carries a significantly elevated risk of permanent lingual nerve damage compared with buccal approach methods. Consequently, it has largely been abandoned in contemporary practice and is now discussed primarily in a historical, medico-legal, or comparative context. Editors working on surgical history texts or medicolegal reports will encounter this term and should capitalise 'lingual split technique' in a style-consistent manner. It must not be confused with sagittal split osteotomy, which is an orthognathic procedure.
Usage
Usage note: Primarily a historical term; if encountered in a contemporary clinical context, query the author. Do not confuse with sagittal split osteotomy.
