Inverted Papilloma of the Maxillary Sinus: A Recurrence Analysis According to Surgical Approaches.

(1) Background: Various surgical approaches have been introduced to resect inverted papillomas (IP) stemming from the maxillary sinus (MS). This study aimed to compare the recurrence rates of IPs originating from the MS according to various surgical modalities. (2) Methods: A total of 155 surgical cases of sinonasal IPs originating from the MS were categorized into three groups according to the surgical approach adopted: endoscopic resection via middle or inferior meatus antrostomy (ESS), ESS with Caldwell−Luc approach or canine fossa trephination (ESS with CL), and expanded endoscopic approaches (ExEA) including endoscopic medial maxillectomy or a prelacrimal recess approach. A Kaplan−Meier curve was generated to examine the recurrence rates. (3) Results: The overall recurrence rate was 5.8% (9/155) with a mean follow-up period of 24.2 months. The recurrence rates for the ESS, ESS with CL, and ExEA groups were 10.0% (7/70), 3.5% (2/57), and 0% (0/28), respectively. The ExEA group had a significantly lower recurrence rate than the ESS group (p = 0.024) and there was a tendency for lower recurrence compared to the ESS within the CL group (p = 0.145). The ExEA required a shorter postoperative hospitalization period than in ESS with CL (p < 0.001). (4) Conclusions: ExEAs to the maxillary sinus such as the PLR and EMM approaches are excellent surgical options for IPs originating from the MS.

A Patient Presentation of Large Septal Perforation Repair Using Inferior Based Contra-Lateral Nasal Floor Flap, a New Surgical Technique for Large Septal Perforation.

ABSTRACT: A nasal septal perforation is a defect of cartilage, bone, or mucosa of nasal septum, which is caused by previous septal surgery, trauma, chemicals, inflammatory disease, or drugs. If conservative managements, such as nasal saline irrigation or ointments, are not effective, surgical treatment can be considered. Various methods for the reconstruction of nasal septal perforation were reported, such as local flaps, free flaps, autografts, allografts, or xenografts. However, there is no standardized method due to low success rate and high recurrence rate, especially in large perforations. The authors report a successful repair case of large anteroinferior nasal septal perforation, using inferior based contralateral nasal floor flap. The authors believe that our method is an effective way to repair large nasal septal perforation and to minimalize donor site morbidity, without using other allografts.

Clinical Factors Influencing the Trial and Purchase of Bilateral Microphones with Contralateral Routing of Signal in Patients with Asymmetric Sensorineural Hearing Loss.

BACKGROUND AND OBJECTIVES: Bilateral microphones with contralateral routing of signal (BiCROS) hearing aid is an option for hearing rehabilitation in individuals with asymmetric sensorineural hearing loss (ASNHL). The clinical factors influencing the trial and purchase of BiCROS were investigated. SUBJECTS AND METHODS: We reviewed the medical records of 78 patients with ASNHL who were recommended to use BiCROS and analyzed the demographic and audiological factors influencing the trial and purchase of BiCROS. RESULTS: Among the 78 patients, 52 (66.7%) availed of the free BiCROS trial and 21 (26.9%) purchased BiCROS. The mean pure tone audiometry (PTA) air conduction (AC) threshold of the better- and worse-hearing ears were 44.2±12.8 dB and 90.7±22.5 dB HL, respectively. The decision for trial or purchase of BiCROS was not influenced by age, sex, duration of hearing loss of the worse-hearing ear, or PTA AC threshold or speech discrimination score of both ears. The first and third quartiles of the PTA AC thresholds for the better-hearing ear of BiCROS buyers were 38.75 dB and 53.75 dB HL, respectively. The counterpart values for the worse-hearing ear were 72.50 dB and 118.75 dB HL, respectively. CONCLUSIONS: The clinical factors analyzed in this study were found to be irrelevant to the trial and purchase of BiCROS in patients with ASNHL. Nevertheless, the distribution range of the auditory thresholds of the subjects using BiCROS can be a useful basis for the counseling of patients with ASNHL and selection of candidates for BiCROS use.
