video assisted endoscopic laryngosurgery using a direct laryngoscope and a long rigid endoscope
Diagnostic and Therapeutic Endoscopy, 2000Co-Authors: Masahiro Kawaida, Hiroyuki Fukuda, Naoyuki KohnoAbstract:EndoLaryngeal microscopic laryngosurgery (microlaryngosurgery) using a direct laryngoscope is the preferred surgical method for treating Laryngeal lesions under general anesthesia. However, this method does not provide a wide-angle view of the larynx and does not allow detailed observations of the ventricle and subglottis of the Laryngeal Cavity, resulting in blind areas. Video-assisted endoscopic laryngosurgery using a direct laryngoscope and a long transurethral rigid endoscope was therefore utilized to allow clear observations and complete resection of Laryngeal lesions in these blind areas. This endoscopic surgical technique is introduced, and clinical cases are presented.

endoscopic observations of the Laryngeal Cavity from multidirections using
The Japan Journal of Logopedics and Phoniatrics, 1997Co-Authors: Masahiro Kawaida, Hiroyuki Fukuda, Naoyuki KohnoAbstract:直達喉頭鏡を用いた喉頭顕微鏡下の観察は優れたものであるが, 喉頭腔のうち, 仮声帯下面や喉頭室, 声帯下面などは死角となる.腫瘍性病変では, これらの部位に浸潤することもあり, 死角部位の詳細な観察法が望まれる.そこで, 泌尿器科で用いられる膀胱・尿道用の側視型硬性内視鏡にカラービデオカメラを接続し, 直達喉頭鏡を通して喉頭腔の多方向内視鏡観察を試みた.カラーテレビモニターに拡大された鮮明な映像を映し出すことができた.通常光源に加え, 喉頭ストロボスコープを使用し, バイブレーター法での観察も行われた.声門部上皮内癌と声門型喉頭癌の2症例に施行したが, いずれも鮮明な映像が得られた.本法を紹介するとともに, 手技や利点について考察した.

Scheme survey frontal section of larynx (human)
2006Co-Authors: Poels, Lambert G.Abstract:Stain: Azan. A pseudostratified epithelium covers the mucosa of the Laryngeal Cavity and vestibulum. At the vocal fold edge (3) the epithelium appears to be nonkeratinizing squamous. The connective tissue is rigidly attached to this edge and merges into the vocal ligament (dense elastic) and vocal muscle. (3) transition of pseudostratified epithelium into squamous epithelium; (5) seromucous glands; (6) ventriculus laryngis; (7) plica ventricularis, with mixed Laryngeal glands; (8) ligamentum vocale as part of the plica vocalis, covered with squamous epithelium; (9) vocal muscle; (10) thyreoarytenoid muscle (pars lateralis); (11) ventricular recess (sacculus laryngis); (12) pseudostratified epithelium

Removal of Laryngeal cancer with thyroid cartilage membrane excision and repair of Laryngeal Cavity with outside thyroid cartilage membrane flap of healthy side: oncologic and functional outcomes
Zhonghua er bi yan hou tou jing wai ke za zhi = Chinese journal of otorhinolaryngology head and neck surgery, 2016Co-Authors: Zhaotang Zhong, Minzhi Liang, Ze ChenAbstract:Objective To study the efficacy and feasibility of removal of Laryngeal cancer with thyroid cartilage membrane excision and repair of Laryngeal Cavity by the outside thyroid cartilage membrane flap of healthy side. Methods A total of 28 patients were reviewed who underwent the removal of Laryngeal cancer with thyroid cartilage membrane excision combined with the repair of Laryngeal Cavity by the outside thyroid cartilage membrane flap in our hospital between 2005 and 2011. Respiratory function, swallowing function, and voice quality of patients after surgery were evaluated. Survival and recurrence were observed with the follow up of five years. Results The decannulation rate was 96.4%. Aspiration rate was 10.7%, but aspiration was completely revolved by swallowing training in the patients. All patients had the voice quality required for communication although they complained of hoarseness after surgery. Tumor recurrence was found in one patient and cervical lymph node metastasis in 2 patients. The three-year and five-year survival rates were 89.3% and 85.7% respectively. Conclusion This surgical procedure was applicable in some of patients with T2 Laryngeal cancer, with good Laryngeal functions after surgery.
