Controversy is a state of prolonged [[dispute]] or [[debate]], usually concerning a matter of conflicting [[opinion]] or point of view.

===== Examples =====
Controversy related to the choice of surgical [[approach]] for [[vestibular schwannoma]] (VS) [[resection]] remains. Whether the [[retrosigmoid]] (RS) or [[translabyrinthine]] (TL) approach should be performed is a matter of [[debate]]. In the context of a lack of clear [[evidence]] favoring one [[approach]], Obaid et al. conducted a [[retrospective]] [[study]] to compare the [[morbidity]] [[rate]] of both surgical approaches
((Obaid S, Nikolaidis I, Alzahrani M, Moumdjian R, Saliba I. Morbidity Rate of
the Retrosigmoid versus Translabyrinthine Approach for Vestibular Schwannoma
Resection. J Audiol Otol. 2018 Aug 22. doi: 10.7874/jao.2018.00164. [Epub ahead

The [[Simpson grading system]]
((SIMPSON D. The recurrence of intracranial meningiomas after surgical treatment. J Neurol Neurosurg Psychiatry. 1957 Feb;20(1):22-39. doi: 10.1136/jnnp.20.1.22. PMID: 13406590; PMCID: PMC497230.)), 
developed in [[1957]] by [[Donald Simpson]], has been considered the gold standard for defining the surgical extent of resection [[World Health Organization grade 1 meningioma]]s. Since its introduction, the [[scale]] and its modifications have generated enormous [[controversy]].
