“…15 Odagiri et al examined 298 tonsillectomy procedures conducted at their institution and reported that while 2.6% of patients in the nonendoscopic group had early-stage hemorrhage, none in the endoscopic group experienced it. 6 In this study, no patient developed early-stage hemorrhage. This indicates that bringing the endoscope close to the lesion and observing the surgical site thoroughly without blind spots may have resulted in adequately performed hemostasis, thereby preventing early-stage hemorrhage.…”

“…Following tonsillectomy, the status of food intake in pediatric patients by type was as follows: in type A (n ¼ 5), 40% of the patients (n ¼ 2) ate "almost all," 40% (n ¼ 2) ate "more than half and less than all," and 20% (n ¼ 1) ate "less than half"; in type B (n ¼ 9), 11% of the patients (n ¼ 1) ate "almost all," 56% (n ¼ 5) ate "more than half and less than all," and 33% (n ¼ 4) ate "less than half"; and in type C (n ¼ 4), 25% of the patients (n ¼ 1) ate "almost all" and 75% (n ¼ 3) ate "more than half and less than all" (►Fig. 6).…”

“…To address this problem, the surgical field was directly screened on a monitor using a paranasal sinus endoscope, and this method was reportedly effective in guiding surgery and confirming hemostasis. 5,6 In addition to endoscopy, other methods of sharing a view of the surgical field include monitoring with headlight-mounted cameras and surgical microscopes. One report indicated that a method of using a surgical microscope during tonsillectomy was effective for separation along the tonsillar capsule.…”

Palatine tonsillectomy is a surgical procedure that novice otolaryngologists should master early and is taught at many medical institutions. Unfortunately, however, the transoral procedure cannot provide a large enough field of view to doctors other than the one performing the operation. Therefore, it is difficult to share the surgical field and provide real-time teaching. Dissection of the wrong layer can cause postoperative bleeding and pain. Our department uses a 70-degree, 4-mm rigid endoscope for palatine tonsillectomy, which makes it possible for preceptors to teach tonsillectomy in real time and to evaluate the condition of the postoperative wound in detail. We classified the postoperative state after tonsillectomy into three stages, based on the degree of residual subcapsular connective tissue. We assessed the association between the amount of residual subcapsular connective tissue and the underlying disease that required indication for tonsillectomy, the postoperative course, and the operation time in 33 patients who had undergone palatine tonsillectomy at our institution between May 2017 and November 2020. We found that the more the subcapsular connective tissue that remained, the less the postoperative pain and bleeding. This association suggests that conserving the subcapsular connective tissue is important. Bringing the endoscope closer to the surgical field to observe the field without blind areas enables adequate hemostasis and easy sharing of the surgical field; therefore, this method is also effective for teaching tonsillectomy to surgical trainees.
