We report a case of GID (gender identity disorder) of the female-to-male type, where her vocal pitch was lowered to her satisfaction by Thyroplasty type 3. The distress of GID patients derives from the contradiction between their sexual physical features and gender self-consciousness. As to the levels of distress and the means patients select to resolve the problems they face, individual variations are great. The present patient did not want either transsexual surgery or hormonal treatment, but merely her vocal pitch lowered. Thyroplasty type 3 successfully lowered her vocal pitch as desired without any complication. Surgical details and key points were described.

Thyroplasty was performed under local anesthesia on male-to-female transsexuals (MTF/GID) as well as patients with adductor spasmodic dysphonia (AdSD).<BR>There were 31 patients with MTF/GID who underwent type 4 thyroplasty during the period from 1999 to 2006. Voice fundamental frequency (F<SUB>0</SUB>) rose in all patients. Mean preoperative F<SUB>0</SUB> was 135Hz, and postoperatively the mean value was 236Hz. Type 4 thyroplasty requires specialized skill, and was found to be effective for pitch elevation surgery in MTF/GID. <BR>Forty-one patients with AdSD underwent type 2 thyroplasty with Titanium Bridge between December 2002 and December 2005. These patients were followed up 1 year postoperatively with a questionnaire. 70% of the patients judged their voice as "excellent, " and the remaining patients as improved to "good" or "fair". Type 2 thyroplasty is a highly effective therapy for AdSD.

In order to study the development of speech in infants with cleft palate, we investigated the development of consonant articulation in two cases (A, B) with cleft soft palate and in two cases (C, D) with cleft lip and palate before and after palatoplasty. We taperecorded their consonants in meaningful speech sounds and transcribed them.We made the following observations: (1) The frequency of consonants in meaningful speech sounds did not vary with the type of cleft or the timing of palatoplasty, and increased radically in the latter half of the second year and the first half of the third year. (2) Glottal stops occurred in the pre-palatoplasty periods but had almost disappeared three to ten months after palatoplasty in cases A, B, and C, whose velopharyngeal function was competent. (3) The speech sounds of these three cases were judged to be intelligible when the numbers of glottal stops decreased, the numbers of voiceless stops accounted for over 50% of all stops, and bilabial voiceless stops [p] appeared.

When Type II thyroplasty is performed, surgical management of the dihedral angle of the midline of the thyroid cartilage is very important. Clinical histoanatomy around the anterior commissure was investigated using whole organ serial sections of the human larynx to make Type II thyroplasty successful. An inner perichondrium did not exist at the dihedral angle in the upper three-forths of the midline of the thyroid cartilage. On the other hand, the inner perichondrium was present at the lower one-forth of the midline of the posterior surface of the thyroid cartilage. The attachment of the collagenous fiber (anterior commissure tendon, Broyles, 1943) extends from the upper portion of the thyroid notch caudalward for approximately upper three-forths of the midline of posterior surface of the thyroid cartilage. The midline of the posterior surface of the thyroid cartilage is only covered with thin mucosa at the laryngeal ventricle level. It is important not to perforate the mucosa when the laryngofissure is performed. In order to make the anterior commissure the proper width, it is important to split the anterior commissure tendon at the mid-line and to spread the glottis while making sure the tendons remain attached to the bilateral thyroid cartilage.

Gender Identity Disorder (GID)は性同一性障害といわれ,生物学的性別と心理社会的性別が解離している病態である。<br>今回われわれはmale to femaleのGID (MTF/GID)症例に対し,話声位(SFF)の基本周波数を上昇させる目的でPitch Elevation Surgeryを施行した。その成績について報告する。<br>症例は1999~2006年に当院を受診し手術を施行したMTF/GIDの32例である。32例に対し甲状軟骨形成術4型(4型)を施行した。そのうち24例には喉頭隆起切除術を併せて施行した。<br>32例全例のSFFは上昇した。術前の平均SFFの基本周波数は133.8 Hz,術後は平均237.8 Hzであった。局所麻酔にて手術を施行しているため,全例ともに術中に患者の納得のいく基本周波数に調節することができ満足が得られた。<br>4型はMTF/GID症例におけるPitch Elevation Surgeryとして有用であると思われた。

痙攣性発声障害は、まれな疾患で病態も全く不明といってよく、有効な治療もないと考えられてきた。現在、神経筋接合部に作用するボツリヌストキシンが痙攣性発声障害に応用され、外来で治療でき恒久的な障害も残さない利点があることから、世界的に普及している。しかし有効期間が3-6カ月であり再注射が必要という問題点もある。われわれは、内転型痙攣性発声障害患者に対して声門過閉鎖の防止を目的に喉頭枠組みを開大し、持続的で再発の可能性が少ない甲状軟骨形成術2型を1997年6月から行い、極めて良好な結果を得ている。そこで2004年10月までに得られた手術実績 (64症例、66件) をもとにそれらの症例をまとめ、その手術適応と手術のコツを中心に述べた。本手術の術式は決して難しくはないが、甲状軟骨の切開、剥離さらに開大幅の調節を慎重に正確に行うことが、手術成功に必要な条件であると考えられた。

Thyroplasty was performed under local anesthesia on male-to-female transsexuals (MTF/GID) as well as patients with adductor spasmodic dysphonia (AdSD).There were 31 patients with MTF/GID who underwent type 4 thyroplasty during the period from 1999 to 2006. Voice fundamental frequency (F0) rose in all patients. Mean preoperative F0 was 135Hz, and postoperatively the mean value was 236Hz. Type 4 thyroplasty requires specialized skill, and was found to be effective for pitch elevation surgery in MTF/GID. Forty-one patients with AdSD underwent type 2 thyroplasty with Titanium Bridge between December 2002 and December 2005. These patients were followed up 1 year postoperatively with a questionnaire. 70% of the patients judged their voice as “excellent, ” and the remaining patients as improved to “good” or “fair”. Type 2 thyroplasty is a highly effective therapy for AdSD.
