作者们在7年中观察了插管后引起的喉肉芽肿9例。男2,女7;均为成人。肉芽肿发生在声带后1/3者8例,中1/3者仅1例;双侧性6例。8例采用喉显微手术摘除,1例保守治疗。插管后喉肉芽肿是少见的并发症。作者们所在医院在7年内插管手术超过7000例,仅发生3例。文献报道的发生率约0.1%。插管引起喉肉芽肿的原因可从以下三方面考虑:(1)插管的性状:管径太粗,形状、硬度和材料不合适以及气囊等对喉粘膜的过度压迫和刺激均能造成局部供血不足与缺氧。插管时用的润滑剂和防腐剂亦可损伤喉粘膜。(2)病员的条件:喉的解剖是基本因素之一。呼吸道在喉平面处弯曲向后,致插管易压迫杓状和环状软骨。女性的喉比男性者 In 7 years, the authors observed 9 cases of laryngeal granuloma caused by intubation. Male 2, female 7; are adults. Granuloma occurred in the vocal cords 1/3 in 8 cases, 1/3 in only 1 case; bilateral in 6 cases. Eight cases were treated with laryngeal microsurgery and one case received conservative treatment. Post-intubation laryngeal granuloma is a rare complication. The author’s hospital had more than 7,000 intubated surgeries in 7 years, with only 3 occurring. The reported incidence of about 0.1%. Causes of intubation caused by laryngeal granuloma can be considered from the following three aspects: (1) intubation traits: diameter is too thick, shape, hardness and material inappropriate and excessive pressure and irritation of the laryngeal mucosa such as airbags can cause local Insufficient blood supply and hypoxia. Intubation with lubricants and preservatives can also damage the laryngeal mucosa. (2) the condition of the patient: the laryngeal anatomy is one of the basic factors. The respiratory tract is curved backwards at the plane of the larynx, which tends to pressure the arytenoid and cricoid cartilage. Female throat than male
