The sensory recovery of noninnervated free flaps used in oral and oropharyngeal reconstruction is analysed retrospectively to evaluate the degree of sensory recovery in different free flaps; and to assess the influence of various clinical and surgical factors on the recovery. A total of 40 patients who underwent oral and oropharyngeal reconstruction with noninnervated radial forearm (24), jejunal (10) or gastro-omental (6) free flaps were studied for at least 12 months postoperatively. The modalities examined were light touch, sharp prick, hot and cold temperature and static two-point discrimination. All the modalities showed statistically significant recovery in all flaps (p<0.05). The degree of sensory recovery for each modality is highest in the radial forearm followed by gastro-omental and lastly jejunal flaps. The differences between radial forearm and gastro-omental/jejunal flaps are statistically significant (p<0.05) except for light touch. The differences between the later two groups of flaps did not show statistical significance (p>0.05). Sensory recovery for all modalities in all flaps was not dependent on sex, age, smoking, flap size, postoperative radiotherapy or follow-up period (p>0.05).

Functional Outcome and Balance Compensation in Patients with Unilateral Vestibular Schwannoma After Surgical Treatment-Short- and Medium-Term Observation.
J Clin Med
January 2025
Department of Otorhinolaryngology Head and Neck Surgery, Medical University of Warsaw, Banacha 1a Str., 02-097 Warsaw, Poland.
: The aim was to evaluate vestibular function in patients with unilateral vestibular schwannoma before and in the short and medium term after surgical treatment to analyze vestibular compensation. The identification of the prognostic factors determining incomplete and slower balance recovery was assessed. Forty-five patients with unilateral vestibular schwannoma treated surgically through the middle cranial fossa and translabyrinthine approach were enrolled in this study.

: Surgery for adolescent idiopathic deformities is often aimed at improving aesthetic appearance, striving for the best possible correction. However, severe and rigid scoliotic curves not only present aesthetic issues but can also compromise cardiopulmonary health and cause early neurological impairment due to spinal cord compression, posing significant risks of morbidity and mortality if untreated. Conservative treatments are ineffective for severe curves, defined by scoliotic angles over 70° and flexibility below 30% on lateral bending X-rays.

: This study aimed to compare two surgical techniques-the free flap of the superficial palmar branch of the radial artery (SPBRA) and the free venous flap (FVF)-to evaluate their efficacy and aesthetic outcomes in repairing finger tissue defects. The goal was to determine which procedure offers faster healing curves and better overall patient outcomes, ultimately improving the quality of life for individuals undergoing these surgeries. : A retrospective study was conducted using the clinical database of Sanliurfa Mehmet Akif Inan Education and Research Hospital, University of Health Sciences, from 1 January 2019 to 1 January 2022.

Department of Dental Surgery, Wroclaw Medical University, 50-425 Wroclaw, Poland.
Background: Sensory disturbances and acquired paresthesia constitute a significant proportion of complications following orthognathic surgery. This systematic review examines the application of photobiomodulation (PBM) in managing these complications and its efficacy in promoting sensory recovery.
Methods: In November 2024, a comprehensive digital search was performed across reputable databases, including PubMed, Web of Science, and Scopus, using carefully selected search terms: "orthognathic surgery" AND (physiotherapy OR physical therapy OR laser OR LLLT OR PBM OR light OR LED OR acupuncture) AND (nerve OR neurosensory OR paresthesia).
Assessing Donor Site Morbidity and Impact on Quality of Life in Free Flap Microsurgery: An Overview.

Department 11, Discipline Plastic and Reconstructive Surgery, Bucharest Clinical Emergency Hospital, University of Medicine and Pharmacy Carol Davila, 050474 Bucharest, Romania.
Donor site morbidity remains a significant concern in free flap microsurgery, with implications that extend beyond immediate postoperative outcomes to affect patients' long-term quality of life. This review explores the multi-faceted impact of donor site morbidity on physical, psychological, social, and occupational well-being, synthesizing findings from the existing literature. Particular attention is given to the functional limitations, sensory deficits, aesthetic outcomes, and chronic pain associated with commonly utilized free flaps.
