Abstract

Transitioning of rhinologic procedures from the operating room to the office setting in selected patients is a rising trend. An effective pain-control, patient-preparation protocol is essential, especially with advanced in-office rhinologic procedures such as hybrid balloon sinus dilation (BSD), in which other procedures such as ethmoidectomy, turbinate reduction, and other procedures are concomitantly performed. A regimen using oral sedation, topical tetracaine gel, topical tetracaine/epinephrine-soaked cottonoid packs, and intranasal local infiltrative anesthesia can vary significantly in effectiveness and be suboptimal at times (as determined by using treated patients as historical controls). A modification of this regimen was subsequently used, incorporating the maxillary nerve block, and qualitative differences were then assessed retrospectively between the two regimens. Twenty-five consecutive patients were retrospectively studied who underwent hybrid BSD procedures in the office setting using the maxillary nerve-block regimen modification. All patients underwent BSD of the sphenoid, frontal, and maxillary sinuses with anterior and partial posterior ethmoidectomies. Five patients also underwent septoplasty, and 18 patients underwent inferior turbinate reduction procedures. Twenty-four patients received oral sedation, and all patients received topical tetracaine/epinephrine-soaked cottonoid packs. The topical tetracaine gel was dropped after 5 patients because it was not felt to be needed anymore. No intranasal local infiltrative anesthesia was used. Several qualitative differences were observed after modifying the patient-preparation regimen incorporating the maxillary nerve block. The most important observation seen with this modification was a consistently reproducible, dense anesthesia coverage over the entire nasal cavity with good paranasal sinus coverage. This modification eliminated intranasal bleeding and swelling associated with intranasal local anesthetic injections. No complications were encountered. This preliminary study provides support for use and further evaluation of the maxillary nerve block for in-office rhinologic procedures. If the trend continues to rise in performing advanced in-office rhinologic procedures in selected patients, the maxillary nerve block may find a place in the patient-preparation protocol.
