resections and/or delicate reconstruction procedures, such as tissue grafting and rotational free flaps, which may be hindered by use of an oral endotracheal tube (ETT). Furthermore, such invasive surgical procedures often have significant postoperative edema negatively impacting patency of the airway, which increases the risks of morbidity and mortality. Elective tracheotomy, as a measure to provide a secure surgical airway, is often warranted to address these potential complications. While an elective tracheotomy may be performed under local anesthesia, there are still

Iatrogenic injury secondary to tracheotomy or tracheal intubation is the most common cause of acquired tracheal stenosis in adults, 1 but each has a different etiology. 2 The frequency of tracheal stenosis after tracheotomy or tracheal intubation is 2% to 2.6% 3 , 4 and 10% to 22%, 5 – 9 respectively. Although symptoms are typically not observed in mild tracheal stenosis, 1% to 2% of patients with tracheal stenosis after tracheotomy or tracheal intubation are symptomatic or have severe tracheal stenosis. 10 – 13 Wheezing or stridor

the fifth vertebral level. Figure 2. Axial computed tomography images obtained 1 week after the emergent tracheostomy. Subcutaneous emphysema and pneumomediastinum have almost disappeared. DISCUSSION The incidence of complications after tracheostomy was reported to be 5.2% in the Japanese literature. 1 In general, complications associated with tracheotomy include bleeding, pneumomediastinum, subcutaneous emphysema, infection, and

Figure 1. ; Preparation for experiment 1. General anesthesia in both groups was induced and maintained with sevoflurane in oxygen for a tracheotomy and placement of femoral artery and vein catheters. Then, a laser Doppler flowmeter probe (ALF21RTM; Advance, Tokyo, Japan) was fixed onto the palatal mucosal surface using a piece of sponge to monitor the palatal mucosal blood flow (PMBF) continuously. After the preparation (tracheotomy and placement of catheters), at least 5 minutes elapsed until the cardiovascular parameters had stabilized when control (time 0) measurements were made.

Figure 1. ; Method of general anesthesia. General anesthesia was induced by oxygen 5 L/min and 5% sevoflurane, and then a tracheotomy was performed, after which general anesthesia was maintained at oxygen 3 L/min and 3% sevoflurane. A cannula was inserted into the femoral artery, and arterial pressure was continuously recorded throughout the experiment using a polygraph and a pressure transducer.
