Surgical Pearls for Safe and Precise Decision-Making during Modified Selective Neurectomy Surgery.

In this short communication: (1) A transcutaneous electrical nerve stimulaton stimulator is a cost-effective solution for the predictable stimulation of mimicry and for precise decision-making. (2) Positioning a simple shatterproof mirror in front of an operated facial half enables the primary surgeon to simultaneously see and stimulate at the operative site and to scrutinize the mimicry for decision-making. (3) A misconception in the literature regarding colors used for tagging "branches for transection" and "branches for preservation" is clarified, and a third tag-color is suggested for times of ambiguity. (4) The principle of distal execution of the surgery and technical considerations are underlined for maximal transection and maximal preservation. The modified selective neurectomy surgery is the current golden standard of post facial paralysis synkinesis treatment, and developing a learning curve in this type of surgery is like walking a tightrope, where the surgeon must keep pushing the limits with precise decision-making and a small margin of error. It is important to be reminded that the first aim is primum non nocere, and the second aim is to improve the condition of patients as much as possible. The above-mentioned principles and solutions increase precision and safety, assisting surgeons to achieve better outcomes.

Contralateral Depressor Labii Inferioris Chemodenervation for Congenital Unilateral Lower Lip Palsy.

INTRODUCTION: Congenital unilateral lower lip palsy - also known as asymmetric crying facies - is isolated asymmetry of the lower lip unilaterally. It is characterized by isolated lower lip asymmetry during smiling and speech. Although etiology is unknown, depressor labii inferioris (DLI) weakness is hold responsible. AIM: Purpose of this study was to evaluate the effectiveness of contralateral depressor labii inferioris botulinum toxin injection on patients' concern levels and patient satisfaction. Ten units of botulinum toxin A injection was carried out to the healthy contralateral side. METHODOLOGY: Eleven patients were treated. Patients' pretreatment and posttreatment concern regarding asymmetry during speech and smiling was evaluated with a questionnaire. Patients' perception of treatment satisfaction was also evaluated with a questionnaire. RESULTS: Mean score related to concern about asymmetric appearance during smiling decreased from 1.6 ±â€Š0.8 to 0.5 ±â€Š0.5. Mean score related to concern about asymmetric appearance during speech decreased from 1.6 ±â€Š0.5 to 0.4 ±â€Š0.5. Eleven out of 11 patients reported improvement with speech whereas 10 out of 11 patients reported improvement with smiling. No weakness about oral competence was reported. CONCLUSION: Most congenital unilateral lower lip palsy patients are concerned regarding their asymmetric appearance while smiling or speaking. Chemodenervation of the contralateral DLI muscle reduces concern levels and has high patient satisfaction. Chemodenervation of the contralateral healthy DLI muscle is a valid, practical treatment option.

The Effectiveness of Asymmetric Dorsal Preservation for Correction of I-Shaped Crooked Nose Deformity in Comparison to Conventional Technique.

Importance: Using asymmetric dorsal preservation (ADP) (pushdown technique for deviated side and letdown technique to the contralateral nondeviated side) is an alternative surgical method to correct osseocartilaginous deviation in crooked nose deformity. Objective: Aim of this study was to evaluate whether ADP rhinoplasty is a good method to address I-shaped crookedness in comparison with conventional midvault deconstructing/reconstructing rhinoplasty. Design, Setting, and Participants: This study was conducted between June 2017 and August 2019. Twenty-two consecutive patients' I-shaped crookedness was addressed with either ADP (n = 10) or conventional midvault techniques (n = 12). Patients were followed up at least for 6 months. Main Outcomes and Measures: Pre- and postoperative frontal photographs and digital screen protractor was utilized for measurement of crookedness in a single-blinded manner. Surgical success were calculated and compared. Results: In ADP group, mean angle of deviation was 10.2 ± 3.7° and 0.5 ± 1.0° pre- and postoperatively, respectively. In control group, mean angle of deviation was 9.5 ± 1.8° and 0.3 ± 0.9° pre- and postoperatively, respectively. Change in angle was statistically significant for both groups. Postoperative calculated mean success rate was 96.3 ± 7.9% and 97.5 ± 8.5% for dorsal preservation and control group, respectively. Eight out of 10 patients in dorsal preservation group and 11 out of 12 patients in the control group achieved the ideal angle of 0°, hence had 100% postoperative surgical success. Conclusions and Relevance: Utilization of dorsal preservation principles for correction of I-shaped crookedness presents as a promising and practical surgical alternative approach that should be in every rhinoplasty surgeon's armamentarium.

Effect of Distal Masseter to Facial Nerve Transfer in Paralytic Patients with Preserved Facial Nerve Continuity on Improving Scaled Measurement of Improvement in Lip Excursion (SMILE): A Vectoral Analysis.

OBJECTIVE: Distal masseter-to-facial neurorrhaphy is an option to improve smile excursion in facial paralysis patients in the early period without truncating the facial nerve truncus and by ensuring the continuity of the facial nerve. This study aimed to study the effect of distal masseter-to-facial neurorrhaphy on smile excursion. METHODS: Charts of eight patients were retrospectively examined. Screenshots showing the best possible smiles were taken from preoperative videos. Screenshots were taken from postoperative videos showing the best combination of a natural smile on the healthy side and a smile with clenched teeth on the paralytic side. Emotrics and Photoshop software were used for computing vertical, horizontal, and overall excursion from facial landmarks. Scaled measurements of improvement in lip excursion and lip angle was evaluated. Symmetry was evaluated by accepting the healthy side as 100 percent, and the paralytic side was calculated as a percentage of the healthy side. RESULTS: Five patients had total facial paralysis and three had facial paresis. Mean postoperative follow-up period was 15.0±10.2 months. The average interval between facial denervation and nerve repair was 14.0±4.1 months (range, 11-23). All neurorrhaphies were coapted end-to-end to either the zygomatic or the buccal branch without an interposition graft. Mean postoperative initial movement occurred at 95.5±20.5 days (range, 72-138). Paralytic side to healthy side horizontal excursion changed from preoperative 72.5±17.4% to postoperative 93.4±6.9%. Vertical excursion changed from preoperative 38.4±24.6% to postoperative 89.3±11.8%. Overall excursion changed from preoperative 68.4±19.6% to postoperative 92.9±10.4%. Paralytic side to healthy side mean lip angle changed from 64.7% preoperative to 95.2% postoperatively. All changes were statistically significant (p<0.05). CONCLUSION: Facial paralysis patients with an asymmetric smile benefit from distal masseter-to-facial nerve transfer and it improves smile excursion dramatically. This effect was especially prominent in the vertical component of the smiling vector.

Modified Composite-Flap Facelift Combined With Finger-Assisted Malar Elevation (FAME): A Cadaver Study.

BACKGROUND: Inadequate release of retaining ligaments during facelift surgery may lead to an unnatural appearance. However, most facelift surgeons are hesitant in transecting these ligaments to avoid possible injury to facial subbranches. OBJECTIVES: In the authors' surgical practice for modified composite flap rhytidectomy, the authors employed the finger-assisted malar elevation (FAME) technique in order to enable safe release of the zygomatic cutaneous ligaments through the prezygomatic space under direct vision. The aim was to evaluate the anatomical basis and safety measures of this technique through a cadaveric dissection study. METHODS: Modified composite-flap facelift with the FAME technique was carried out in 22 fresh cadaver hemi-faces. All facial nerve subbranches were dissected thoroughly to assess for any evidence of injury during facelift, and to evaluate the safety of the operation. The relations among the facial nerve, zygomatic cutaneous and masseteric ligaments, orbicularis oculi muscle, and malar fat pad were investigated. RESULTS: Finger dissection of the prezygomatic space allows safe release of the zygomatic cutaneous ligaments as well as adequate entry to a proper surgical plane above the zygomatici muscles under direct vision, while leaving the malar fat pad and overlying structures attached to the skin without the need of a transblepharoplasty approach. CONCLUSIONS: This study by the authors shows that a modified composite-flap facelift with FAME technique is a safe procedure that allows adequate and effective repositioning of an en-bloc composite flap that produces balanced and harmonious rejuvenation of the midface and lower face without the need of a separate midface lift.

Surgical Approach to the Thick Nasolabial Folds, Jowls and Heavy Neck-How to Approach and Suspend the Facial Ligaments.

Patients with thick skin typically present with a redundant, baggy, lax skin envelope together with prominent nasolabial folds, jowls, and a heavy neck. Durable and natural-appearing rejuvenation is not possible unless the deformities are addressed adequately and harmoniously in these patients. Traditional superficial musculoaponeurotic system techniques do not include surgical release of the zygomatic cutaneous ligaments and repositioning of descendent malar fat pad, and may lead to an unbalanced, unnatural appearance and the lateral sweep phenomenon. Additional attempts to improve unopposed nasolabial folds such as fat grafting to malar region are more likely to result with a "stuffed" look, far from a natural and rejuvenated appearance, and must therefore be avoided. The facelift techniques including true release of the anchoring ligaments of the midface and allowing adequate repositioning of saggy tissues are ideal for these patients to obtain harmonious, natural result. Despite the extensive dissections, maximal release, and maximal lateral pull, additional maneuvers, e.g., platysmaplasty, subplatysmal fat removal, or partial resection of submandibular glands may be required for satisfying result in patients with heavy neck. In this article, the authors outline the relevant anatomy of the facial retaining ligaments and their implications to surgical management of patients with heavy skin are discussed.

Association of Autologous Costal Cartilage Harvesting Technique With Donor-Site Pain in Patients Undergoing Rhinoplasty.

IMPORTANCE: Postoperative pain at the donor site is a common morbidity following autologous costal cartilage grafting. OBJECTIVE: To evaluate postoperative pain at the donor site after the use of a muscle-sparing costal cartilage harvesting technique compared with a muscle-cutting technique using electrocautery. DESIGN, SETTING, AND PARTICIPANTS: Designed as a controlled trial without randomization, this prospective, comparative cohort study was conducted between January 1, 2016, and March 31, 2017. Participants included 20 patients who underwent rhinoplasty for various cosmetic and functional complaints from January 1, 2016, to February 28, 2017. Of the 20 patients, 1 was excluded owing to an infection that developed on postoperative day (POD) 7. Patients were grouped by the rib harvesting technique used that was either a muscle-sparing technique (n = 11) or a muscle-cutting technique (n = 8). Skin incisions for both groups were carried out with a blade. Transection of muscle fascia and muscle fibers was performed with monopolar electrocautery in the muscle-cutting technique group. Blunt dissection with a hemostat was performed in the muscle-sparing technique group. All other surgical techniques were identical. MAIN OUTCOMES AND MEASURES: Postoperative pain was assessed with visual analog scale scores for resting pain and movement pain. Eight pain measurements were noted at the sixth postoperative hour and on PODs 1, 2, 3, 7, 15, 30, and 45. During the hospital stay, the postoperative need for analgesics was recorded daily as the number of analgesic infusion vials used. RESULTS: The 19 patients in the study included 11 women and 8 men whose mean age (SD) was 33.2 (10.3) years The mean (SD) visual pain analog scale scores for resting pain and movement pain were consistently higher in the muscle-cutting technique group than in the muscle-sparing technique group. This difference was statistically significant on PODs 2, 3, and 15 for resting pain and on PODs 2, 3, 7, 15, 30, and 45 for movement pain. The mean postoperative need for analgesic infusion vials during hospital stay was higher in the muscle-cutting technique group, and the difference was statistically significant on POD 2 (1.9 [0.6] vials vs 1.0 [0.9] vials; P = .02). CONCLUSIONS AND RELEVANCE: Both resting and movement pain at the donor site was significantly reduced in the muscle-sparing technique group during the postoperative period, findings that align with anecdotal reports in the literature. Routine use of the muscle-sparing technique in autologous costal cartilage harvesting is recommended to reduce postoperative pain. LEVEL OF EVIDENCE: 2.

Olfactory Dysfunction Associated With Neuro-Behçet Disease.

INTRODUCTION: Neurologic involvement associated with Behçet disease (BD) is defined as a different entity: Neuro-Behçet disease (NBD). Behçet disease presents with olfactory dysfunction. It is not known whether this is the consequence of mucosal involvement or neurologic involvement. OBJECTIVE: The aim of this study was to investigate whether olfactory dysfunction was further aggravated as the result of neurologic involvement. METHODS: Sixteen patients diagnosed with NBD and 16 healthy control patients with similar demographic characteristics were recruited as the healthy control group. Expanded Disability Status Scale (EDSS) scoring was used for quantification of neurological disability. All diagnoses were confirmed and categorized with magnetic resonance imaging studies in all patients individually: parenchymal or nonparenchymal. A well-established test of orthonasal olfaction developed at the CCCRC was used. Correlation analysis was carried out. RESULTS: The mean CCCRC score of NBD patients was 4.60 out of 7, and this group was diagnosed to be moderately hyposmic, whereas the average score of the control group was 6.5; the difference was significant (P < 0.0001). CCCRC scores of NBD patients were significantly lower compared both healthy control patients and those of BD patients reported in the literature. Mean EDSS score of NBD patients was 1.75 ±â€Š1.0 out of 10 (0-no neurologic disability and 10-worst neurologic disability). Magnetic resonance imaging of NBD patients revealed 4 nonparenchymal and 12 parenchymal patients. Neuro-Behçet disease patients with parenchymal involvement presented with (worse) EDSS scores. Mean olfactory CCCRC score of this group was 4.38 whereas the average olfactory score of the vascular group was 5.25 out 7. Average EDSS score of vascular group was 0.75, much better compared to higher average neurologic disability score of 2.08 for the parenchymal group. Significant correlation existed between the duration of NBD and both olfactory and neurologic dysfunction scores. CONCLUSION: Neuro-Behçet disease present with aggravated olfactory dysfunction compared to BD. Neurologic involvement-especially parenchymal involvement-seems to deteriorate the olfactory dysfunction. Duration of disease is correlated with this severity of dysfunction.

Current updates in nasal bone reshaping.

PURPOSE OF REVIEW: To review recent studies on nasal osseocartilaginous anatomy, osteotomy techniques and contemporary methods of nasal bone reshaping carried out under direct vision. RECENT FINDINGS: Current cadaver studies on osseocartilaginous vault anatomy, osteotomy techniques provide valuable information that can reduce outcome variability and increase reliability of osteotomies. Nevertheless, osteotomes have limitations and contemporary approaches - namely, piezoelectric instrumentations, osteoectomy, and osteotomy carried out under direct vision - can provide valuable solutions to certain shortcomings. Contrary to widespread understanding, extended wide periosteal dissection is the common thread in newly introduced methods which claim enhanced control, reduced soft tissue trauma, and reproducible results. Comparative and cadaver studies show promising results regarding protection of underlying mucosa, reduced comminuted fractures, reduced postoperative ecchymosis, and edema. SUMMARY: Improvements in nasal bone reshaping are promising for better esthetic and functional outcomes. Nevertheless, these approaches need to be validated by randomized controlled trials and test of time before being incorporated in routine surgical practice.

A clinically unsuspected nasopharyngeal sarcoidosis.

Sarcoidosis is a multi-system disease which rarely involves the upper respiratory tract, leading to hoarseness, dysphagia, laryngeal paralysis, and upper airway obstruction. The Waldeyer's ring involvement in sarcoidosis is also very rare. In this article, we report a 32-year-old male case in whom a nasopharyngeal mass was detected based on the Waldeyer's ring involvement due to sarcoidosis.

Effect of Postrhinoplasty Taping on Postoperative Edema and Nasal Draping: A Randomized Clinical Trial.

BACKGROUND: Edema persists for months after rhinoplasty. Numerous modalities have been described to counteract postoperative edema. OBJECTIVE: To evaluate the effect of postrhinoplasty taping (PRT) on nasal edema and nasal draping. DESIGN, SETTING, AND PARTICIPANTS: In this randomized clinical trial, 57 patients undergoing rhinoplasty at a tertiary reference center from August 1, 2014, to January 31, 2015, were assigned to a control group or to 2- or 4-week PRT groups. Baseline nasal thickness was measured with ultrasonography at the nasion, rhinion, supratip, and tip, and mean nasal skin thickness (MNST) was calculated. Participants in each group were categorized by the baseline MNST measurement from the lowest to greatest MNST; those in the upper half were categorized as having thick skin; those in the lower half, thin skin. The control group underwent no PRT after the removal of external packing. Patients in the 2- and 4-week PRT groups received additional taping during the allocated time. Data were collected from August 1, 2014, to June 31, 2015. Follow-up was completed on June 31, 2015, and data were analyzed from July 1 to August 1, 2015. MAIN OUTCOMES AND MEASURES: Postoperative measurements of MNST were performed at the end of weeks 1, 3, and 5 and month 6. RESULTS: Of the 57 total patients (33 male and 24 female patients; mean [SD] age, 30.0 [11.7] years), 17 were in the 2-week PRT group; 20, the 4-week PRT group; and 20, the control group. Compared with the control group, 4-week PRT had a significant effect on the supratip (P = .001). Comparisons of MNST with the control group revealed significant effects of 2-week (P = .02) and 4-week (P = .007) PRT. The effect on the tip was not significant (P = .052). Postrhinoplasty taping had no effect in thin-skinned patients. Comparison among thick-skinned patients revealed a significant effect on the MNST (P = .01) and the rhinion (P = .02) but not the tip (P = .06) and supratip (P = .07). CONCLUSIONS AND RELEVANCE: Postrhinoplasty taping helps the skin envelope to compress to the underlying framework and decrease postoperative edema. The procedure can be used particularly in thick-skinned patients, in whom skin draping and nasal refinement is crucial to the surgical outcome. LEVEL OF EVIDENCE: 1.

Dynamometric Analysis of Normative Auricular Stiffness and Comparison With Operated Prominent Ears.

AIM: Stiffness of the auricular cartilage is the main determining factor for the choice of operative technique of the prominent ear deformity. The aim of this study is to evaluate the stiffness of normal appearing ears objectively and quantitatively, compare the results with the operated prominent ear patients, and present prospective short-term dynamometric evaluation of the operated prominent ear patients. PATIENTS AND METHODS: A total of 190 volunteers without ear deformities were recruited and 9 age groups were formed: group (5-9), group (10-14), group (15-19), group (20-24), group (25-29), group (30-34), group (35-39), group (40-49), and group (50+). Total 28 ears (14 patients) with otoplasty were included in the study as group (operated 5-9) and group (operated 10-14). In addition, 3 patients with prominent ear deformity were prospectively followed for dynamometric changes that occur with otoplasty operation. The auriculocephalic angle (ACA) was measured once and auricle to scalp distance was measured at 4 different standardized levels. Ear stiffness was measured on each ear individually at 4 different points over the antihelix using digital computer-aided dynamometry. Each ear was compared in terms of ACA, distance, and dynamometric values. FINDINGS: Dynamometric values tend to increase with age, which increase and peak around 35 years of age and declines after 40 years of age. Measurements of the first 2 age groups were statistically different compared with the other groups. Postoperative dynamometric measurements (DNM) of group (operated 5-9) were similar with normative values of group (5-9) and postoperative satisfaction visual analogue scale (VAS) score was 92.8%. Postoperative DNM of group (operated 10-14) were higher compared with normative values of group (10-14) for each different measuring level and the postoperative satisfaction VAS score was 75.3. A total of 3 patients with prominent ears had lower dynamometric values preoperatively; these values approached closer to normative values of their age group postoperatively. CONCLUSIONS: Results show that auricular cartilage stiffens and malleability decreases with increased age. This stiffness peaks in the 35-39 age group and declines after 40 years of age. Dynamometric values increase, at all levels, suggesting increased cartilage stiffness is related to age. In the scope of these results, cartilage sparing techniques are more suitable for 5 to 14 years of age and cartilage-cutting techniques are more suitable for older patients.

Electromyographic Evaluation of Temporalis Muscle Following Temporalis Tendon Transfer (Facial Reanimation) Surgery.

UNLABELLED: Facial paralysis is a significant functional and aesthetic handicap. Many techniques have been defined for facial reanimation. The aim of the study was to evaluate postoperative electromyographical (EMG) activity of temporalis muscle to assess the potential neural impairments related to the surgical procedure. METHODOLOGY: Four patients with facial paralysis were operated with the temporalis muscle tendon transfer technique. Simultaneous surface electromyographic (sEMG) activity at first postoperative year from the bilateral temporalis and masseter muscles was obtained at mandibular rest position and then during maximal clenching. RESULTS: Patients were followed for a minimum period of 18 months. Surface electromyographic evaluations during passive state revealed similar values for the operated and contralateral side. Measurements during active "clench-smiling" of the jaw revealed similar amplitudes for both muscles of the operated side in all cases except case #2. Case #2 revealed lower values for both measurements of temporalis and masseter muscles of the operated side compared with the contralateral side. Dissonant results of case #2 can be the consequence of impaired temporalis muscle activity because of the tension on the muscle as a consequence of overcorrection. CONCLUSION: Temporalis muscle transfer to the perioral region does not hinder contractility of the muscle as long as the facial deformity is not overcorrected.

Wide-Open Dorsal Approach Rhinoplasty for Droopy Noses.

BACKGROUND: Because rhinoplastic surgery predominantly deals with the osseocartilaginous skeleton, droopy noses with thick skin remain a problem to be solved. In these noses, neglecting excess skin can impair long-lasting and complete correction of the nasal deformity. As these noses already require redundant dorsal skin resection, surgical manipulations can be executed entirely through the dorsal skin excision window instead of the transcolumellar approach. OBJECTIVE: The wide-open dorsal approach rhinoplasty (WoDAR) was developed to allow removal of excess dorsal skin and reconstruction of the nasal osseocartilaginous framework through the excised dorsal skin avoiding a transcolumellar incision. MATERIALS AND METHODS: Nine male patients with thick skin and significantly ptotic noses were operated with WoDAR. The cosmetic appearance of the noses was evaluated by the patients before and after the operation using a visual analog scale (VAS). The nasal obstruction symptom evaluation (NOSE) scale was evaluated individually preoperatively and postoperatively. The nasolabial angle (NLA) was measured preoperatively, at the third, twelfth, and twenty-fourth months postoperatively. Dorsal scars were evaluated by means of the Stony Brook's scar evaluation scale (SBSES). RESULTS: Patients (mean age: 51.4 ± 4.8 years) were followed for an average duration of 20.6 ± 8.4 months. Cosmetic evaluation revealed that the mean patient preoperative VAS score was 23.3 ± 25.6, whereas the postoperative VAS score was 92.6 ± 14.8. Preoperative and postoperative NOSE scores were 79.5 ± 16.5 and 11.5 ± 11.5, respectively. The mean preoperative NLA was 72.9 ± 2.9° and at the third and twelfth month postoperatively was 92 ± 6.5 and 91 ± 5.4. The NLA measurements of all four patients followed for 24 months revealed less than 2° derotation compared to third postoperative month. The mean SBSES score was 4.1 ± 0.8 out of 5. CONCLUSION: WoDAR allowed esthetically and functionally pleasing outcomes. This advantageous technique can be regarded as a surgical alternative for carefully selected aged patients with severely ptotic, thick-skinned noses who might otherwise end up with unsatisfying results both for surgeon and patients.
