This case report aimed to verify the effect of lingual frenectomy on the functional anatomical aspects of the tongue, the phonetic-acoustic characteristics, and the magnitude of tongue movement in the phonemes [ɾ] and [l] after the lingual frenectomy. The anatomical characteristics of the lingual frenum and the functional aspects of the tongue were evaluated using the Protocol for Evaluation of the Lingual Frenum. The phonetic-acoustic particularities of speech were assessed through formant analysis using PRAAT software, and the evaluation of the magnitude of tongue movements was conducted via ultrasonographic analysis with Articulate Assistant Advanced (AAA) software. After the assessments, the patient was referred for the lingual frenectomy and was reevaluated after 7 and 14 days of healing. It was observed through the functional anatomical evaluation that the patient showed modifications in the shape of the tongue tip, greater elevation of the tongue in the oral cavity, and improvement in the contact of the tongue tip with the labial commissures. The acoustic evaluation of speech and the ultrasonographic assessment of tongue movements indicated a longer emission time for the words, increased verticalization and anteriorization of the tongue during speech production, which were more evident for the phoneme [ɾ]. Thus, the instrumental evaluations contributed to the clinical assessment, facilitating the observation of the patient's progress after the lingual frenectomy, identified in the analysis of the formants and highlighted through the ultrasonographic analysis of the tongue.
本病例报告旨在验证舌系带切除术对舌的功能解剖学方面、语音声学特征以及舌系带切除术后音素[ɾ]和[l]中舌运动幅度的影响。使用舌系带评估方案评估舌系带的解剖特征和舌的功能方面。通过使用PRAAT软件进行共振峰分析来评估语音的语音声学特性，并通过使用高级发音助手（AAA）软件进行超声分析来评估舌运动的幅度。评估后，患者接受舌系带切除术，并在愈合7天和14天后进行重新评估。通过功能解剖学评估观察到，患者舌尖形状出现改变，口腔内舌的抬高增加，舌尖与唇角的接触改善。语音声学评估和舌运动的超声评估表明，单词的发音时间延长，语音产生过程中舌的垂直化和前移增加，这在音素[ɾ]中更为明显。因此，仪器评估有助于临床评估，便于观察舌系带切除术后患者的进展，这在共振峰分析中得到确认，并通过舌的超声分析得以突出显示。
