The lingual tonsillar hyperplasia in relation to unanticipated difficult intubation: is there any relationship between lingual tonsillar hyperplasia and tonsillectomy?

The lingual tonsillar hyperplasia (LTH) is a rare and dangerous condition of the upper airway because it is one of several risks during intubation which can cause serious complications like cardiac arrest, cerebral anoxia, and death. The LTH is rarely detectable during a routine oropharyngeal examination. The lingual tonsil is of particular interest to forensic medicine to assess cases with malpractice in connection with intubation difficulties. Our study looked at how often autopsy specimens had enlarged lingual tonsils and whether any relationship existed between LTH and tonsillectomies. In total, 497 corpses were examined. Only in 16 cases (3.2%), an enlarged lingual tonsil was detected. Of the 16 cases, 10 (62.5%) had normal palatine tonsils; the other 6 cases (37.5%) had no palatine tonsils or were scarred, atrophied, or only remnants remained. Statistically, it was not possible to prove any relationship between enlarged lingual tonsils and tonsillectomies. From the forensic point of view, a description of the lingual tonsil should appear in special cases in autopsy reports. When reviewing malpractice cases, special anatomic features should be described.
