Objective: Many lateral approaches to the brain require the temporary and partial dissection of the temporal muscle. Atrophy of the muscle is frequently observed after several months or years, which can be both cosmetically disturbing and functionally impairing. Some patients complain of limited mouth opening and pain during mastication. Although the respective craniotomies – pterional, frontolateral and temporal – are among the most frequently used approaches in neurosurgery, a systematic assessment of the postoperative complaints has never been performed so far. In a pilot study “Mastication After Craniotomy” (SmallMAC) we evaluate the subjective impairment of patients after pterional, frontolateral or temporal craniotomy using the standardized international Oral-Health-Impact-Profile (OHIP) 14 score sheet.

Methods: The OHIP-G14 is the German version of the internationally standardized questionnaire for oral health and asks the patients to assess their situation over the past 7 days. All answers are given a score from 0 (never) to 4 (very often). In total, 60 patients will be included who undergo brain surgery through a pterional, frontolateral or temporal approach for a benign intracranial process (e.g. aneurysm or meningioma). The questionnaire is answered right before surgery (baseline), 3 months and 15 months after surgery.

Results: We will present the results of the postoperative assessment of 40 patients 3 months after surgery. The postoperative OHIP-14 score is significantly higher than preoperatively. The results of this ongoing study reveal that patients suffer from pain and functional impairment after partially dissecting the temporal muscle during a standard lateral neurosurgical approach.

Conclusion: The OHIP-G14 score sheet seems to be a suitable questionnaire to assess the functional oral health related impairment after neurosurgical approach through the temporal muscle. The final results of the SmallMAC-study will reveal whether further efforts are necessary to improve the postoperative masticatory functional impairment in neurosurgical patients.
