其實黐脷根(tongue Tie, ankyloglossia) 會否影響兒童語言發展遲緩, 現時在醫學界仍有爭論. 而小兒有輕微黐脷根, 在看過了耳鼻喉科醫生和言語治療師後, 我再上過超過30 websites, 看過超過100篇中英文章, 我不相信耳鼻喉科醫生和言語治療師的意見, 因為我發覺在這專題上, 他們並沒有足夠資料,書本上的知識可能已是過時了.
我傾向是有影響小兒遲說話,說話吃力和發音不正(Difficulty making (articulating) the t, d, z, s, th, n, and l sounds as your young child learns to speak.) (The most common is Ws as Ls; for example the word "lemonade" would come out as "wemonade.")
在上網找Tongue Tie資料的同時, 竟意外發現老爺和先生都有輕微黐脷根, 而我先生竟告訴我他說中, 英文都感"吃力"(他是跨國企業的中層), 他說講說話令他舌頭很倦, 他竟同意了他自己都做手術.
有文章話:
倘若舌繫帶較短,那舌頭的活動就會受到影響了,這就好像小狗脖子上的狗鏈若很短,那狗狗一定是不能到處亂跑的。這種情形,醫學上稱之為「舌繫帶縮短症」。
現在我先生要放狗鏈, 小兒又如何呢?可惜anesthesia 有機會令小朋友(小兒未滿4歲)腦細胞死亡(

), 真是仍需考慮....我會再找醫生傾.
以下是其中一些資料:
根據史丹福大學在2千年所做的一項調查,美國有4.8%的新生兒舌繫帶是過短的,且男生與女生比起來,男生是2.6%,女生是1%。
臨床上,有些學者醫師依據小朋友將舌頭往前伸的動作,評估出舌繫帶的輕重程度:
A. 輕微舌繫韌帶過短:指寶寶舌頭所能伸出來的長度在12~16mm。
B. 中等舌繫韌帶過短:指寶寶舌頭伸出的長度在8~11㎜。
C. 重度舌繫韌帶過短:指寶寶只能伸出3~7㎜。
D. 完全舌繫帶沾黏:寶寶舌頭所能向前伸的長度在3㎜以下。
寶寶需要剪舌繫帶嗎?
寶寶如果舌繫帶有問題到底需不需要動手術呢?林孝禺醫師說,家長在考慮手術前,最好先評估一下再做決定。
1.哺乳問題:媽媽因哺乳時困難,在Baby出生後,為了哺乳方便,可考慮進行評估。18世紀古羅馬時代的時候,有產婦會用他們的長指甲,直接將寶寶的舌繫帶切開,結果常導致出血或感染的後遺症,這樣的手術到現在一直被持續討論當中。
2.語言發展:擔心舌繫帶對寶寶說話造成影響?特別是在學中文和英文時所需要的捲舌音和齒間音,容易使孩子發音不準或說不出來。其實需要語言治療的小朋友,不一定就有舌繫帶的問題;因為牙齒的發育、舌頭本身的大小、舌頭的感覺及運動功能,都能補償舌頭較短限制,也可以說出標準的構音。一般認為可以到三歲時,語言確實有構音障礙時再說,沒有必要提早手術來預防語言問題的發生。
手術可以由簡單的外科組織切除、縫合,到利用電刀或是雷射的方式均可。但是手術的適切性都值得家長與小兒牙科,或口腔外科、小兒外科等專業醫師進行評估、討論後再決定。儘量減少孩子痛苦與恐懼的考慮下,做最安全與適合的手術建議,或是簡單的定期追蹤,不一定需要立刻做臨床處理。

Speech
Under-developed oral kinaesthesia is the result of individuals with a tongue tie having a very poor sense of the geography of the mouth, because they have such a limited range of lingual movements. Speech problems occur which are difficult to correct by conventional means because they cannot memorize the correct movements of speech, or be sure of always achieving them. Adults develop methods of speech which mask their difficulties with sounds.
Both adults and children often try to speak with a small oral aperture, so that they can make the lingual contacts required for pronouncing consonants; others speak slowly, softly or loudly. Nearly all patients past toddler stage are aware of the movements their tongue cannot make. Clarity in rapid speech is almost always impossible for a tongue-tied person to achieve.
The movements that tongue tie renders difficult may vary from patient to patient but some movements - such as lingual elevation to the upper teeth and horizontal lingual protrusion - are consistently difficult or impossible to achieve because of the pull of the tight lingual frenum on the floor of the mouth and on the tongue. Other movements (whether articulatory or unrelated to speech) can only be achieved under optimal conditions: during careful speech, after prolonged speech therapy, when concentrating, and when talking slowly.
Thus it is seen that many with tongue tie learn to compensate for their limited tongue mobility by adopting alterations of movements. These are rarely successful since they are often conspicuous or inefficient.
