Objective: The aim of this experimental study was to evaluate the use of a clinically available perichondrium graft as an adjunct to surgical tendon repair.
Methods: Eight male New Zealand white rabbits of similar height and weight were used in this study. The left and right Achilles tendons were used as the experimental and control group, respectively. Perichondrium grafts were harvested from the right ears of the rabbits. Both Achilles tendons were clearly cut and repaired. After the repair, the perichondrium graft was wrapped around the tendon repair sites of the left Achilles tendons. Rabbits were sacrificed after six weeks and the tendons were examined macroscopically and histopathologically.
Results: Macroscopically and histopathologically, less adhesion occurred when the perichondrium graft was wrapped around the tendon repair site compared to the control group.
Conclusion: Perichondrium graft may isolate the repaired tendon and may reduce scar formation and adhesions during the healing period.

Cervical subcutaneous emphysema and pneumomediastinum without pneumothorax are exceedingly rare complications following rhinoplasty, with limited cases reported in the literature. This report presents a case of revision septorhinoplasty using autologous costal cartilage, where the patient complained of a sore throat 36 hours postoperatively. On physical examination, cervical subcutaneous emphysema was palpated, and radiologic evaluation confirmed both cervical subcutaneous emphysema and pneumomediastinum.

Objective: This study aimed to assess the functional and clinical outcomes of endoscopic Type 1 tympanoplasty in patients with chronic otitis media and tympanic membrane perforations, focusing on hearing improvement and graft success rates.
Methods: This retrospective study included 46 patients with dry tympanic membrane perforations who underwent endoscopic Type 1 tympanoplasty. Audiometric data, including pure tone averages (PTA) and air-bone gap (ABG) measurements at four frequencies (500, 1000, 2000, and 4000 Hz), were collected preoperatively and postoperatively.

Objective: This study aimed to assess the efficacy of a novel modified asymmetric chondro-perichondrial island graft in tympanoplasty. The design features a longer anterior segment compared to the posterior segment, addressing limitations of symmetrical grafts. We investigated the impact of this modified graft on hearing improvement and graft success rates in patients undergoing tympanoplasty surgery.

Objectives: Our objective is to evaluate the prevalence of tympanic membrane (TM) retractions and management of signs of Eustachian tube dysfunction (ETD) in both children and adults following type 1 tympanoplasty or myringoplasty. Furthermore, to identify potential risk factors for developing ETD and TM retractions.
Methods: Retrospective cohort study of 423 patients (5-86 years of age) undergoing 452 procedures.
