Endoscopic spinal surgery using a new tubular retractor with 15 mm outer diameter.

Purpose: To assess whether the instrument handling and image quality of endoscopic spinal decompression procedures is adequate and effects the treatment of degenerative spinal disorders. Material and Methods: Forty-six patients underwent endoscopic procedures for radicular pain or sensorimotor deficit due to a degenerative disorder using a 15mm tubular retractor. Endoscopic video recordings were reviewed with focus on instrument handling and intraoperative complication. At final follow-up the clinical outcome was assessed via a standardized questionnaire including the Oswestry Disability Index (ODI) Neck Disability Index (NDI), Odoms criteria and a personal examination focusing on pain, and sensorimotor deficits. Results: Forty out of 46 patients attended a final follow-up (86.9%). The mean follow-up time was 51.8 month (range 15-84 month). At final follow-up, of patients who were operate at the lumbar spine 93.9% and at the cervical spine 85.7% were free of radicular pain, no weakness was documented in 84.9% of cases after lumbar and 85.7% after cervical spine procedure, and according to Odoms criteria clinical success was noted in 84.5% and 100%, respectively. The mean ODI was 9.0% and mean NDI was 11.7%. The dural tear rate was 4.3%, all dural tear were closed endoscopically. The recurrent disc herniation rate was 6.1%. Conclusions: Endoscopic decompression using a 15m tubular retractor offers a good view onto the surgical field and a high clinical success rate. The decompression of degenerative pathologies in bimanual technique is not limited by a 15mm tubular retractor.

Smith-Robinson procedure with and without Caspar plating as a treatment for cervical spondylotic myelopathy: A 26-year follow-up of 23 patients.

PURPOSE: The purpose of this study was to assess long-term follow-up data after anterior cervical decompression and fusion (ACDF) with and without Caspar plating (ACDF + PS) for the treatment of cervical spondylotic myelopathy (CSM) with special focus on functional outcome, pain, and repeat surgery for adjacent segment disease (ASD). METHOD: Hospital records of 45 patients who were affected by CSM and underwent ACDF or ACDF + PS at least 17 years ago were reviewed. Information about diagnosis, surgical report, pre- and postoperative clinical process, and complications was analyzed. Clinical outcome was assessed using a standardized questionnaire including the Neck Disability Index (NDI), modified JOA-score, Odom's criteria, limitations in quality of life, and questions about the current neurological status and pain. RESULTS: Twenty-three patients with a mean follow-up of 26 years were evaluated. ACDF was performed in nine and ACDF + PS in 14 patients, respectively. At follow-up 78.3% of patients were free of pain, 91.3% had no motor deficit, 73.9% had no sensory deficit, and 60.7% had no gait disturbance. The current mean NDI is 14% (range 2-44%), the mean modified JOA-score was 17.2 (range 15-18). According to Odom's criteria 78.3% of patients had clinical success. In four patients repeat surgery was indicated due to pseudarthrosis or symptomatic ASD (17.4%). CONCLUSIONS: ACDF and ACDF + PS yield significant decrease in neck pain, a significant increase in sensorimotor function and a high rate of clinical success. Patients with preoperative gait disturbance completely recovered in about 60% of cases. Overall prevalence for ASD was 17.4% after 25 years.

Improvement of sensory function after sequestrectomy for lumbar disc herniation: a prospective clinical study using quantitative sensory testing.

BACKGROUND: Previous studies have investigated sensory recovery in patients with lumbar disc herniation using rather subjective methods. There have been no reports on changes of sensory function in patients suffering from a preoperative sensory deficit using quantitative sensory testing (QST). The aims of this prospective study were (1) to assess the recovery of preoperative sensory dysfunction after lumbar sequestrectomy and (2) to quantify the strength of relationship between a sensory deficit and the patient's quality of life. METHODS: We applied the QST protocol of the German Research Network on Neuropathic Pain (DFNS) in fifty-two patients with a single lumbar disc herniation confirmed on MRI treated by lumbar sequestrectomy. Further evaluation included a detailed medical history, a physical examination, numeric rating scale for leg, EQ-5D questionnaire, and thermometer. RESULTS: Disc surgery resulted in a significant reduction of leg pain and a significant gain of quality of life. Thermal, mechanical, and vibration perception thresholds showed an obvious side-to-side difference preoperatively (p < 0.005). An early recovery of mechanical and vibration perception thresholds was detected, whereas cold perception needed more than 6 months to recover (p < 0.05). Quality of life was independent from perception thresholds, but correlated significantly with pain reduction. CONCLUSION: Our data clearly show that there is a subjective and quantifiable improvement in sensory dysfunction postoperatively. The current data suggest that a sensory dysfunction does not influence a patient's quality of life.

Recovery of Impaired Somatosensory Evoked Fields After Improvement of Tongue Sensory Deficits With Neurosurgical Reconstruction.

Somatosensory evoked fields (SEFs) induced by tongue stimulation can be useful as an objective parameter to assess sensory disturbances in the tongue. However, whether tongue SEFs can be useful as a clinical, objective follow-up assessment method of tongue sensation after oral surgery is unknown. We describe 2 cases in which tongue SEFs were successfully used in clinical assessment. Two patients with unilateral tongue sensory deficits caused by lingual nerve injury during lower third molar extraction were recruited. Both patients underwent surgery to repair the damaged nerve, and all tongue sensory evaluations were performed once before and once after surgery. SEFs were recorded by stimulating the affected and unaffected sides of the tongue separately, and cortical activity was evaluated over the contralateral hemisphere. The unilaterality of the deficit also was assessed. In both patients, stimulation of the unaffected side evoked reproducible cortical responses before and after surgery. Both patients also recovered some sensation after surgery, given that presurgery stimulation of the affected side failed to evoke cortical activity whereas postsurgery stimulation evoked cortical activity on both sides. Sensation was initially highly lateralized in both patients but was restored to approximately normal in the postsurgery evaluation. Finally, both patients rated their subjective tongue sensations on the affected side over 50% better after the surgical intervention. These cases indicate that tongue SEFs may have a clinical use as an objective parameter for assessing the course of tongue sensory recovery.

Outcome analysis of cubital tunnel decompression.

BACKGROUND: Cubital tunnel decompression is a commonly undertaken upper limb procedure. Most studies compare the different techniques of decompression; however, only a few have specifically investigated the outcome of ulnar nerve decompression. AIM: The aim of this study was to investigate the outcome of ulnar nerve decompression following cubital tunnel syndrome. METHODS AND RESULTS: A total of 174 ulnar nerve decompression cases were identified from the upper limb surgery database with complete data available for 136 cases. Simple decompression was performed in 110 (80.88%) cases, and in 26 (19.12%), anterior subcutaneous transposition was also supplemented. These operations were performed at three different hospitals by surgeons of different levels of experience. The most common cause of cubital tunnel syndrome was idiopathic. The outcome was satisfactory in 86% of cases. No obvious association was demonstrated between the outcome of surgery and duration of symptoms, presence of co-morbidities or the type of surgery performed. CONCLUSION: This is the largest outcome analysis of the results of ulnar nerve decompression at the elbow. Good results following nerve decompression were attained in 86% of cases without any significant effect of duration of symptoms or co-morbidities on the outcome of surgery. It is hoped that the findings of the current study will help general practitioners, junior doctors and surgeons in their management and pre-operative consultation with patients having cubital tunnel syndrome.

[Destruction of the Humeral Head in Sensory Deficit due to the Spinal Hemorhagia. Case Report]. / Destrukce hlavice humeru pri senzitivním deficitu po mísní hemoragii - kazuistika.

Degenerative changes of the shoulder are a common complication in patients after spinal cord injury. The main cause is chronic overload to the shoulder joint due to manual wheelchair propulsion and transfers. Reduced shoulder function has a significant impact on all aspects of daily life. Shoulder arthroplasty in this group of patients is a challenging procedure because of the unique demand on the shoulder. This report presents the case of a wheelchair user who additionally experienced a complete loss of sensation around her shoulder. As a result of a repetitive strain during transfers from the wheelchair to the ground, the humeral head was destroyed.

Drug-resistant temporal lobe epilepsy is associated with postural control abnormalities.

Epilepsy is responsible for falls that are not systematically associated with seizures and that therefore suggest postural impairment. There are very few studies of postural control in patients with epilepsy and none of them focus on temporal lobe epilepsy (TLE), although part of the vestibular cortex is located in the temporal cortex. The aim of this study was to evaluate the characteristics of postural control in a homogeneous population of patients with complex partial TLE. Twenty-six patients with epilepsy and 26 age-matched healthy controls underwent a sensory organization test combining six conditions, with and without sensory conflicting situations. Patients with epilepsy displayed poorer postural control, especially in situations where vestibular information is necessary to control balance. In addition to potential antiepileptic drug side effects, vestibular dysfunction could be related to the temporal pathology. Our study allows for a better understanding of the mechanism underlying falls in this population of patients.

[The management of a single Miller-I type gingival recession at the maxillar incisor with single tunnel technique combined with enamel matrix derivative and connective tissue graft. A case report]. / Felso metszofogat erinto Miller-I típusú inyrecessio korrekciója zománcmátrix-proteinnel kombinált subepithelialis kötoszöveti Graft-tal es Single Tooth Tunnel technikával. Esetismertetés.

Gingival recession defect in the dentition are routinely encountered in periodontal practice and presents a challenge for a periodontist. Mucogingival surgical procedures aim to restore both gingival function and aesthetics. Recently as the population is getting to be more concerned about aesthetics the aesthetical indications are more relevant. In the presented case a coronally advanced flap prepared by single tunnel technique and combined with subepithelial connective tissue graft and enamel matrix derivatives (EMD) has been employed for root coverage in a Miller's class I recession. The combined technique used resulted in approximately 100% root coverage in the treated site after 6 months. Treatment outcomes met the patient's aesthetic demands and also eliminated her root sensitivity.

Restless genital syndrome before and after clitoridectomy for spontaneous orgasms: a case report.

INTRODUCTION: Females despairing of restless genital syndrome (ReGS) may request clitoridectomy for treatment of unwanted genital sensations. Aim. The aim of this study was to report persistence of ReGS despite clitoridectomy. METHODS: Following a clitoridectomy for spontaneous orgasms, a 77-year-old woman was referred to our clinic for persistent unwanted genital sensations and feelings of imminent orgasm. An in-depth interview, routine and hormonal investigations, electroencephalography (EEG) and magnetic resonance imaging (MRI) of the brain and pelvis were performed. The localizations of genital sensations were investigated by manual examination of the ramus inferior of the pubic bone (RIPB) and by sensory testing of the skin of the genital area with a cotton swab. MAIN OUTCOME MEASURES: The main outcome measures included sensitivity of dorsal nerve of the clitoris in RIPB and MRI-pelvis. RESULTS: Genital dysesthesias, paresthesias, intolerance (allodynia) for tight clothes, aggravation of symptoms during sitting, restless legs, and overactive bladder were diagnosed. Laboratory assessments, and EEG and MRI of the brain were in agreement with aging, but all results were within the normal range. MRI of the pelvis disclosed varices of the uterus and of the left ovarian vein, and a visible scar in the region of the clitoris. Sensory testing of the genital area showed various points of static mechanical hyperesthesia at the left dermatome of the pudendal nerve. Manual examination of the RIPB also elicited the genital sensations at the left side of the vagina at about the 3 o'clock position. CONCLUSIONS: This patient fulfilled all clinical criteria of ReGS that is believed to be caused by neuropathy of the left pudendal nerve. Clitoridectomy abolished spontaneous orgasms for a great part but not completely, and it did not diminish the typical dysesthesias, paresthesias, and feelings of imminent orgasms that typically belong to ReGS. Clitoridectomy is no optional treatment of ReGS. There is a need for publications of ReGS in general medical journals.

Efficacy of Laminoplasty in Improving Sensory Disturbances in Patients with Cervical Spondylotic Myelopathy: A Prospective Study.

OBJECTIVE: Upper extremity sensory disturbances are primary symptoms that affect the quality of life (QOL) of patients with cervical spondylotic myelopathy. Although laminoplasty is 1 of the surgical options, its effects on sensory disturbances have remained unclear. We aimed to determine whether surgical intervention would improve the sensory disturbances of patients with cervical spondylotic myelopathy. METHODS: We conducted a prospective clinical trial of 101 patients who had undergone open door laminoplasty. For an objective sensory assessment, we measured the current perception thresholds (CPTs) in the patients' forearms and palms using PainVision PS-2100. For a subjective sensory assessment, numbness in the upper extremities was rated using a visual analog scale (VAS). Using the VAS scores, the patients were divided into those with improvement and without improvement. Their self-reported 36-item short-form health survey and Japanese Orthopaedic Association cervical myelopathy evaluation questionnaire scores were compared. RESULTS: The postoperative CPTs in relationship to the preoperative CPTs at 3, 6, and 12 months was 99.3%, 98.1%, and 93.8% in the forearm and 93.6%, 90.6%, and 87.8% in the palm, respectively. The corresponding postoperative numbness VAS scores were 63.8%, 50.5%, and 48.0%. At 12 months postoperatively, the 36-item short-form health survey physical and role component summary scores, cervical spine function effectiveness rates, upper and lower extremity function, and QOL items in the Japanese Orthopaedic Association cervical myelopathy evaluation questionnaire were significantly higher in the improvement group. CONCLUSIONS: Our findings have indicated that improvement in postoperative subjective sensory disturbances will occur relatively earlier and will be significantly greater than the improvement in objective sensory disturbances. Furthermore, improvement in the subjective sensory disturbances contributes to functional spinal cord recovery and patients' health-related QOL.

Posterior instrumented fusion without neural decompression for incomplete neurological deficits following vertebral collapse in the osteoporotic thoracolumbar spine.

Previous reports have emphasized the importance of neural decompression through either an anterior or posterior approach when reconstruction surgery is performed for neurological deficits following vertebral collapse in the osteoporotic thoracolumbar spine. However, the contribution of these decompression procedures to neurological recovery has not been fully established. In the present study, we investigated 14 consecutive patients who had incomplete neurological deficits following vertebral collapse in the osteoporotic thoracolumbar spine and underwent posterior instrumented fusion without neural decompression. They were radiographically and neurologically assessed during an average follow-up period of 25 months. The mean local kyphosis angle was 14.6 degrees at flexion and 4.1 degrees at extension preoperatively, indicating marked instability at the collapsed vertebrae. The mean spinal canal occupation by bone fragments was 21%. After surgery, solid bony fusion was obtained in all patients. The mean local kyphosis angle became 5.8 degrees immediately after surgery and 9.9 degrees at the final follow-up. There was no implant dislodgement, and no additional surgery was required. In all patients, back pain was relieved, and neurological improvement was obtained by at least one modified Frankel grade. The present series demonstrate that the posterior instrumented fusion without neural decompression for incomplete neurological deficits following vertebral collapse in the osteoporotic thoracolumbar spine can provide neurological improvement and relief of back pain without major complications. We suggest that neural decompression is not essential for the treatment of neurological impairment due to osteoporotic vertebral collapse with dynamic mobility.

Autologous olfactory [corrected] mucosal transplant in chronic spinal cord injury: an Indian Pilot Study.

STUDY DESIGN: Prospective Pilot Study. OBJECTIVES: To determine the safety and feasibility of autologous olfactory mucosal transplantation into the spinal cord in chronic spinal cord injured using the technique developed by Carlos Lima et al. SETTING: Spinal Injury Center, New Delhi. METHODS: Five chronic, motor complete, traumatic spinal cord injury (SCI) patients with neurological level C5-T12 underwent the procedure. Participants were assessed at baseline and at 6 monthly intervals. Safety and tolerability were evaluated through monitoring for any adverse events and tests including magnetic resonance imaging (MRI) evaluation. Efficacy assessment was done through neurological, functional and psychological evaluation, electrophysiological studies and urodynamics. RESULTS: Surgery was tolerated well by all American Spinal Injury Association (ASIA) Impairment Scale (AIS) A participants. The only AIS B participant lost sensory scores significantly after surgery but is gradually regaining it. MRI evaluation revealed a syrinx in one participant and increase in length of myelomalacia in four participants. There were no other adverse findings on MRI evaluation. There was no significant improvement in any of the neurological, electrophysiological or urodynamic efficacy variables. Statistically significant improvement was seen in functional scores as evaluated by Spinal Cord Independence Measure, Beck Depression Inventory scores and life impact scores on International Spinal Cord Injury Scale. CONCLUSIONS: The procedure is relatively safe and feasible in AIS A participants with thoracic level injuries at 18 month follow-up. No efficacy could be demonstrated which could be attributed to the procedure.

The surgical burden of disease and perioperative mortality in patients admitted to hospitals in Victoria, Australia: a population-level observational study.

OBJECTIVES: Comprehensive reporting of surgical disease burden and outcomes are vital components of resilient health systems but remain under-reported. The primary objective was to identify the Victorian surgical burden of disease necessitating treatment in a hospital or day centre, including a thorough epidemiology of surgical procedures and their respective perioperative mortality rates (POMR). DESIGN: Retrospective population-level observational study. SETTING: The study was conducted in Victoria, Australia. Access to data from the Victorian Admitted Episodes Dataset was obtained using the Dr Foster Quality Investigator tool. The study included public and private facilities, including day-case facilities. PARTICIPANTS: From January 2014 to December 2016, all admissions with an International Statistical Classification of Diseases-10 code matched to the Global Health Estimates (GHE) disease categories were included. PRIMARY AND SECONDARY OUTCOME MEASURES: Admissions were assigned a primary disease category according to the 23 GHE disease categories. Surgical procedures during hospitalisations were identified using the Australian Refined Diagnosis Related Groups (AR-DRG). POMR were calculated for GHE disease categories and AR-DRG procedures. RESULTS: A total of 4 865 226 admitted episodes were identified over the 3-year period. 1 715 862 (35.3%) of these required a surgical procedure. The mortality rate for those undergoing a procedure was 0.42%, and 1.47% for those without. The top five procedures performed per GHE category were lens procedures (162 835 cases, POMR 0.001%), caesarean delivery (76 032 cases, POMR 0.01%), abortion with operating room procedure (65 451 cases, POMR 0%), hernia procedures (52 499 cases, POMR 0.05%) and other knee procedures (47 181 cases, POMR 0.004%). CONCLUSIONS: Conditions requiring surgery were responsible for 35.3% of the hospital admitted disease burden in Victoria, a rate higher than previously published from Sweden, New Zealand and the USA. POMR is comparable to other studies reporting individual procedures and conditions, but has been reported comprehensively across all GHE disease categories for the first time.

Dorsal root ganglionectomy for the diagnosis of sensory neuropathies. Surgical technique and results.

BACKGROUND: Inflammatory diseases stand out among sensory neuronopathies because, in their active phase, they can be treated with immunosuppressive agents. Immunosuppressive therapy may present severe adverse effects and requires previous inflammatory activity confirmation. Sensory neuronopathies are diagnosed based on clinical and EMG findings. Diagnostic confirmation and identification of inflammatory activity are based on sensory ganglion histopathological examination. We describe the surgical technique used for dorsal root ganglionectomy in patients with clinical/EMG diagnosis of sensory neuronopathies. METHODS: The sensory ganglion was obtained from 15 patients through a small T7-T8 hemilaminectomy and foraminotomy to expose the C7 root from its origin to the spinal nerve bifurcation. In 6 patients, the dural cuff supposed to contain the ganglion was resected en bloc; and in 9 patients, the ganglion was obtained through a longitudinal incision of the dural cuff and microsurgical dissection from the ventral and dorsal roots and radicular arteries. All ganglia were histopathologically examined. RESULTS: No ganglion was found in the dural cuff in 2 patients submitted to en bloc removal, and the ganglion was removed in all patients who underwent microsurgical dissection. All but 2 patients that had ganglion examination presented a neuronopathy of nerve cell loss, 3 with mononuclear inflammatory infiltrate. These patients underwent immunosuppressive therapy, and 2 of them presented clinical improvement. No surgical complications were observed. CONCLUSIONS: Microsurgical dorsal root ganglionectomy for diagnosing inflammatory sensory ganglionopathies was effective and safe. Although safe, en bloc resection of the proximal dural cuff was not effective for this purpose.

Transverse sacral fractures with anterior displacement.

Transverse fractures of the sacrum with anterior displacement are the rarest type of transverse sacral fractures. They usually occur at the S1-S2 region in suicide jumpers. A clinical study was performed to evaluate the diagnosis, treatment and outcome of transverse sacral fractures with anterior displacement. We present six patients with a transverse fracture of the sacrum with anterior displacement. All patients presented with bowel and bladder dysfunction, perineal anesthesia, sensory and motor deficits at the lower extremities. Prompt diagnosis of the sacral fracture was obtained in five of the six patients. Operative treatment including lumbosacral laminectomies, spine instrumentation and fusion was done in all patients. Neurological recovery was almost complete in one patient, incomplete in four patients, and none in one patient. Although reduction of the fracture was not ideal in many of these patients, long-term clinical and radiographic follow-up, and neurological improvement were rewarding.

Relationship between sensory recovery and advancement distance of oblique triangular flap for fingertip reconstruction.

PURPOSE: Oblique triangular flaps often need extensive advancement for fingertip coverage. The purpose of this report is to retrospectively investigate the relationship between sensory recovery and advancement distance of oblique triangular flaps. METHODS: Fourteen consecutive fingertip amputations in 11 patients were treated with oblique triangular flaps between 2005 and 2006. These cases had been regularly followed up (range, 14-21 months) until sensory recovery of the fingertip covered with the flap reached a plateau, and then final sensory condition was evaluated with the Semmes-Weinstein monofilament test and a moving 2-point discrimination test, in addition to evaluation of existence of dysesthesia. RESULTS: Dysesthesia existed in 7 fingers, and there was an associated a significant difference between a flap advancement distance of more than 12 mm and a flap advancement distance of less than 12 mm. In an objective evaluation of whether the 2.83 monofilament (0.086 g) could be recognized in the Semmes-Weinstein test, there was also an associated significant difference between a flap advancement distance of more than 12 mm and a flap advancement distance of less than 12 mm. CONCLUSIONS: Good sensory recovery occurred in cases with less than 12 mm flap advancement. In cases where the flap was advanced more than 12 mm, sensory disturbance of the fingertip occurred and did not subside. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.

Investigation of infraorbital nerve injury following zygomaticomaxillary complex fractures.

The aim of this study was to investigate the severity of infraorbital nerve injury following zygomaticomaxillary complex fractures and to estimate the treatment methods facilitating its functional recovery. A total of 478 patients with unilateral zygomaticomaxillary complex fractures were treated. Infraorbital nerve sensory disturbances were diagnosed in 64.4% of the patients. Injury of the infraorbital nerve was expressed as asymmetry index, which was calculated as a ratio between the affected side and the intact side electric pain detection thresholds at the innervation zone skin before treatment and 14 days, 1, 3, 6 and 12 months postoperatively. A mean asymmetry index of 0.6 +/- 0.03 and 1.9 +/- 0.5 was registered for 57 (11.9%) patients with hyperalgesia and for 251 (52.5%) patients with hypoalgesia, respectively. As a result of retrospective analysis of infraorbital nerve sensory disturbances and its functional recovery, infraorbital nerve injury severity was classified as mild, moderate and severe. It was found that the dynamics and outcome of the functional infraorbital nerve recovery depend on the severity of the injury and the presence of infraorbital canal damage. Function was completely recovered within 3 months after treatment in cases with mild nerve injury. In moderate cases, complete recovery was seen within 6 months and in 34.6% of the severe cases, within a 12-month period after treatment when infraorbital nerve decompression was performed according to the stated indication. Treatment based on infraorbital nerve injury classification offers a better prognosis for complete recovery of the infraorbital nerve function.

Sifting through the Evidence: A Comprehensive Review and Analysis of Neurotization in Breast Reconstruction.

BACKGROUND: An untoward outcome following breast reconstruction is diminished or complete loss of sensation. As the reconstructive paradigm continues to evolve, sensory restoration following reconstruction remains a research focus. Despite the multitude of published outcomes, there is marked heterogeneity across studies, thus confounding published outcomes. This study critically appraises the literature to summarize outcomes and establish a framework to guide clinical practice and future research. METHODS: A literature review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines in an effort to perform a meta-analysis. The Ovid MEDLINE, PubMed, Embase, Scopus, Cochrane, and ClinicalTrials.gov online databases were queried to capture all publications between 1990 and 2017 that investigated postreconstruction breast sensation. The primary outcome of interest was breast sensation following both implant-based and autologous reconstruction with or without neurotization. Secondary outcomes of interest included time to sensory testing and patient-reported outcomes. RESULTS: Overall, 503 titles were screened, from which 37 articles were ultimately included for analysis, accounting for 1299 patients. There was major methodologic variability and inconsistent measurable outcomes across studies. It can be deduced that postoperative sensation returns spontaneously and unpredictably, neurotization enhances the magnitude and rapidity of sensory restoration when compared to nonneurotized reconstruction, and a sensate reconstruction improves patient-reported outcomes. CONCLUSIONS: Significant study design discrepancies exist, making it difficult to combine data and assess results. To effectively study breast sensation and the impact of neurotization, future investigation will depend on standardizing the way in which breast sensation is measured.
