Post-operative vestibular function outcomes evaluated by video Head Impulse Test in patients with non-vestibular schwannoma cerebellopontine angle tumors
Objectives
To evaluate post-operative semicircular canal function in patients with non-vestibular schwannoma (VS) cerebellopontine angle (CPA) tumors by video Head Impulse Test (vHIT).
Methods
Fourteen patients with non-VS CPA tumors who underwent surgery. The gain in vestibulo-ocular reflex (VOR) was examined pre- and post-operatively for the semicircular canals in patients with non-VS CPA tumors.
Results
Ten of 14 patients showed semicircular canal dysfunction in one or more of the semicircular canals pre-operatively and VOR gain was significantly correlated with hearing function. Two patients showed improvement in one or more semicircular canals at 1 month after surgery compared to the pre-operative results. Significant improvements in VOR gain were observed when comparing VOR gain at 1 month and 6 months after surgery.
Conclusions
Detailed evaluation of semicircular canal function was achieved by using vHIT in patients with non-VS CPA tumors. The good prognosis for vestibular function as evaluated by vHIT post-operatively was confirmed in patients with non-VS CPA tumors when compared to those in patients with VS. As improvement may occur post-operatively, surgical approaches that preserve the vestibular nerves and semicircular canals should be chosen for patients with non-VS CPA tumors, regardless of preoperative vestibular function. Even if vestibular function deteriorates immediately after surgery, it may improve over time if the nerve is preserved.
期刊介绍：
The international journal Auris Nasus Larynx provides the opportunity for rapid, carefully reviewed publications concerning the fundamental and clinical aspects of otorhinolaryngology and related fields. This includes otology, neurotology, bronchoesophagology, laryngology, rhinology, allergology, head and neck medicine and oncologic surgery, maxillofacial and plastic surgery, audiology, speech science.
Original papers, short communications and original case reports can be submitted. Reviews on recent developments are invited regularly and Letters to the Editor commenting on papers or any aspect of Auris Nasus Larynx are welcomed.
Founded in 1973 and previously published by the Society for Promotion of International Otorhinolaryngology, the journal is now the official English-language journal of the Oto-Rhino-Laryngological Society of Japan, Inc. The aim of its new international Editorial Board is to make Auris Nasus Larynx an international forum for high quality research and clinical sciences.
