    In this paper, the authors provide a new proof of the following result, originally proved by \textit{V. V. Nikulin} [Math. USSR, Izv. 16, 573--601 (1981; Zbl 0465.22007)]. Theorem. For every \(n\geq 2\), there exists only finitely many maximal arithmetic reflection groups \(\Gamma \leq \mathrm{Isom }(\mathbb{H}^{n}).\)
