Nasal-tracheal intubation is commonly used for most head and neck procedures including dental and oral surgical operations. Various complications are reported in the literature, many of these deal with the mechanical diffculty of the nasal route.' 2'3 This report concerns a complication which is related to intra-operative trauma with subsequent postoperative necrosis of the skin over the ala of the nose. (Figure 1) We

In all cases, it is preventable with proper armamentarium. The two factors contributing to the necrosis was the position of the nasal tracheal tube and the length of the procedure. This complication has been eliminated in subsequent procedures of comparable length by ( 1) cutting the tube length as it exits the nose, (after successful intubation and confirming bilateral lung expansion and equal breath sounds), (2) A 1350 angle adapter' is placed in the tube insuring a low proffle, (3) A flexible connector is then used between the tube and the hoses from the anesthesia machine.

prevents undue pressure to the nose during the operation in addition to avoiding inadvertent extubation by the surgeon or assistant, (4) The tube is then stabilized with a tube tree,5 (5) Other methods of stabilizing endotracheal tubes have also been described.6-7-8 Using these modifications, adapting the length of the tube, stabilizing, and visualizing it eliminates this unusual complication of transient nasal skin necrosis.
